National Culture and Stock Price Crash Risk

Abstract

We examine the relation between individualism and stock price crash risk. Using a sample of 36

countries over the period 2000–2009, we find that firms in individualistic cultures are associated

with higher stock price crash risk. We further explore possible explanations for this positive

effect of individualism on stock price crash. We find that individualism instills confidence in

both traders and managers, whose aggressive trading and bad-news hoarding lead to stock price

crash risk. Overall, our findings suggest that national culture is an important determinant of

stock price crash risk.

1 Introduction

Stock price crash risk refers to the likelihood of a sudden, drastic decline in stock price, which

captures asymmetry in risk attributes and thus is important for investment decisions and risk

management. One stream of literature attributes stock price crashes to excessive trading behav-

ior of overconfident investors, causing excess volatility and possible crashes (e.g., Chen et al.,

2001; Hong and Stein, 2003). Another stream of literature (e.g., Hutton et al., 2009; Jin and

Myers, 2006; Kothari et al., 2009) shows that stock price crashes result from managers’ hoarding

of bad news, a behavior that leads to stock price crashes if bad news is accumulated beyond

a threshold level. Given that the effect of culture on the behavior of individuals is well docu-

mented in the literature (North, 1990; Williamson, 2000), the question whether culture affects

the trading behavior of investors and bad-news hoarding behavior of managers remains largely

unanswered. We fill this gap by examining the relation between culture and stock price crash

risk.

We follow existing literature (e.g., Liang Shao, 2010) and use Hofstede (2001)’s individualism

index as a proxy for national culture because of its dominant position in cross-cultural studies.

According to Hofstede (2001), individualism reflects the degree to which people focus on their

internal attributes, such as their own abilities, to differentiate themselves from others. Using a

sample of 19,080 firms from 36 countries over a period from 2000 to 2009, we find that individ-

ualism has a positive effect on stock price crash risk. This effect remains valid under various

robustness checks including an instrumental variable (IV) approach and a hierarchical linear

estimation model. Our findings suggest that firms headquartered in individualistic countries

are associated with higher stock price crash risk.

After establishing a positive effect of individualism and stock price crash risk, we turn to ex-

ploring possible mechanisms under which individualism leads to stock price crash risk. Previous

research (e.g., Chui et al., 2010; Ferris et al., 2013; Kagitcibasi, 1997; Markus and Kitayama,

1991) shows that individualistic cultures engender overconfidence, the tendency of individuals

to think that they are better than they actually are in terms of several individual characteris-

tics such as ability, judgment, or prospects for successful life outcomes. We consider two ways

in which individualism has a positive effect on stock price crash risk through overconfidence:

overconfidence of traders and overconfidence of managers.

First, we examine whether the positive effect of individualism on stock price crash risk

1

stems from trading activities by overconfident investors. It can be argued that traders from

individualistic cultures are more overconfident because research has shown that people from

individualistic cultures tend to be more overconfident (e.g., Kagitcibasi, 1997; Markus and Ki-

tayama, 1991). In addition, trading activities of overconfident traders can lead to higher stock

price risk. Overconfident traders often overestimate the accuracy of their own evaluations re-

sulting in an underestimation of risk and increasing the differences of opinions among them,

leading to excessive trading and excess volatility (Grinblatt and Keloharju, 2009; Markus and

Kitayama, 1991; Odean, 1998; Statman et al., 2006). Therefore, excessive trading of overconfi-

dent traders and excess volatility can increase stock price crash risk. Indeed, Hong and Stein

(2003) theoretically show that a stock price crash is caused by differences in opinions of in-

vestors, which is a form of overconfidence whereby each investor irrationally thinks that his

private signal is more precise than the others’.

We therefore argue that if individualism instills overconfidence in traders whose excessive

trading leads to stock price crashes, then the positive effect of individualism on stock price crash

risk should be stronger where the presence of overconfident traders are most likely in evidence.

Given that behavioral finance models predict higher trading volume in the markets where there

are more overconfident traders (e.g., Odean, 1998), we use trading volume as a proxy for the

presence of overconfident traders and find that the positive relation between individualism

and stock price crash risk becomes more pronounced in stocks with higher trading volume,

which supports our conjecture that one way individualism has a positive effect on stock price

crash risk is through trading activities by investors whose individualistic cultures engender their

overconfidence.

Second, the positive effect of individualism on stock price crash risk can also arise from bad-

news hoarding behavior of overconfident managers. Since people from individualistic cultures

tend to be more overconfident (e.g., Kagitcibasi, 1997; Markus and Kitayama, 1991), it can be

argued that managers from individualistic cultures are more likely to be overconfident. There-

fore, if these managers engage in bad-news hoarding activities, it can lead to higher stock price

crash risk. Overconfident managers often overestimate the returns to and their own ability to

control the outcomes of the investment projects that they undertake, as well as ignoring or

explaining away privately observed negative feedback on such projects and engaging in corpo-

rate risk-taking (e.g., Heaton, 2002; Malmendier and Tate, 2005, 2008; Malmendier et al., 2011).

Therefore, if overconfident managers misperceive ongoing negative NPV projects as value creat-

2

ing and continue these projects for extended period of time, poor performance of these projects

will accumulate, and, beyond a tipping point, will lead to stock price crashes.

Existing literature has provided support for bad-news stockpiling by overconfident managers

from different perspectives. Ahmed and Duellman (2013) find that overconfident managers tend

to delay loss recognition, a form of bad-news hoarding behavior. Schrand and Zechman (2012)

find that earnings misstatements, another form of bad-news hoarding, are largely a result of

managerial overconfidence because managers are overoptimistic that future performance will

be sufficient to cover the reversal or that the misstatements will go undetected. As a result, a

firm’s “bad news” could be withheld for too long and its bad performance accumulates, making

its future stock price crashes more likely. Using the U.S. sample, Kim et al. (2016) document

that compared with firms with non-overconfident managers, firms with overconfident managers

are associated with higher stock price crash risk.

Along this line, we argue that if individualism encourages overconfidence in managers whose

bad-news hoarding causes stock price crash risk, then the positive effect of individualism on stock

price crash risk should be stronger in firms run by overconfident managers. Due to the unavail-

ability of international data on managerial overconfidence, we follow Schrand and Zechman

(2012), Hirshleifer et al. (2012), and Ahmed and Duellman (2013) to use several investment-

based proxies for managerial overconfidence, such as overinvestment and risky investment. We

find that the positive effect of individualism on stock price crash risk is more pronounced in

firms with more overconfident managers. This finding supports our hypothesis that individ-

ualism leads to stock price crashes through the bad-news hoarding behavior of overconfident

managers.

Our study makes two contributions to the literature. First, it adds to a strand of the

literature that links culture to financial markets and corporate decisions. Existing research doc-

uments that national culture plays an important role in corporate capital structure (Chui et al.,

2002), country-level financial systems (Kwok and Solomon, 2006), life insurance consumption

(Chui and Kwok, 2007), momentum profits (Chui et al., 2010), home bias in international asset

allocation (Beugelsdijk and Frijns, 2010), cash holdings Chen et al. (2015), and stock price

synchronocity (Eun et al., 2015). We provide evidence in support of the link between culture

and stock price crash risk.

Second, we contribute to a growing body of the literature that examines the factors con-

tributing stock price crash risk. Extant research shows that earnings management (Hutton

3

et al., 2009), equity incentives to CEOs (Kim et al., 2011a), complex tax shelters (Kim et al.,

2011b), institutional ownership (An and Zhang, 2013), the adoption of international financial

reporting system (DeFond et al., 2015), audit quality (Robin and Hao, 2015), accounting con-

servatism (Kim and Zhang, 2016), overconfident managers (Kim et al., 2016), and corporate

governance (Andreou et al., 2016) all affect stock price crash risk. Our study documents a

dimension of culture as a factor that can contribute to stock price crash risk.

Our study is closely related to Callen and Fang (2015), who examine the relationship be-

tween religiosity at the county level and stock price crash risk in the U.S. They find that firms

headquartered in counties with higher levels of religiosity exhibit lower levels of future stock

price crash risk, consistent with the view that religion, as a set of social norms, is associated with

managerial bad-news hoarding. We focus on national culture in a cross-country analysis rather

than in the U.S. only. Our findings are consistent with the view that individualism encour-

ages bad-news hoarding behavior of overconfident managers and aggressive trading behavior of

overconfident traders.

The remainder of this study is organized as follows. Section 2 describes sample data and

variable constructions. Section 3 presents emprical findings and robustness checks. Section 4

discusses possible mechanisms. Section 5 concludes.

2 Data, Variable Construction, and Descriptive Statistics

2.1 Data

We collect data on stock prices, stock returns, and exchange rates from Datastream, and firm-

level accounting data from Worldscope for all publicly traded firms from 36 countries over the

period from 2000 to 2009. Following the literature (e.g., Hutton et al., 2009; Jin and Myers, 2006;

Kim et al., 2011a), we exclude firms with less than 26 weeks in a given year of stock trading

data, financial and utility firms, and American Depository Receipts and Global Depository

Receipts. We also drop observations with negative sales and year-end stock prices less than

$1. We obtain culture data from Hofstede (2001) and macroeconomic data the World Bank

World Development Indicators (WDI) database. We exclude observations with missing values

for culture and control variables and observations with insufficient information for constructing

the crash risk measures. We winsorize all variables (except the crash dummy) at the top and

bottom 1% to mitigate the effect of outliers. The final sample has 100,751 firm-year observations

4

for 19,080 firms from 36 countries.

2.2 Stock Price Crash Risk

As in Jin and Myers (2006), we first estimate firm-specific weekly returns for firm i in week t

using the following expanded market model:

rijt = αi + β1rmjt + β2(rUSt + EXjt) + β3rmjt−1 + β4(rUSt−1 + EXjt−1) (1)

+ β5rmjt−2 + β6(rUSt−2 + EXjt−2) + β7rmjt+1 + β8(rUSt+1 + EXjt+1)

+ β9rmjt+2 + β10(rUSt+2 + EXjt+2) + εijt,

where rijt is the return on stock i in country j in week t, rmjt is the market return for country

j in week t, calculated as the equally weighted average of all weekly individual stock returns in

country j in week t (excluding stock i), and rUSt is the U.S. market return in week t. EXjt

is the change in country j’s U.S. dollar exchange rate and εijt represents unspecified factors.

The expression rUSt + EXjt translates U.S. market returns into local currency units. To allow

for nonsynchronous trading, we also include lead and lag terms for the market index returns

(Dimson, 1979).

To minimize potential data errors, we set to missing all those weekly stock returns that

exceed 200%. We require that each country’s weekly market portfolio consist of at least 10

stocks. In computing the weekly market returns, we also exclude the returns within the 0.1%

extremes at the top and bottom of each country’s stock return distribution. Finally, each

country and each stock must have at least 24 weekly observations during a particular year.

The firm-specific weekly return for firm i in week t, denoted by Wit, is defined as the natural

logarithm of one plus the residual return (εit) from the above regression equation.

Following prior work (e.g., Kim et al., 2011a), we use three measures of firm-specific crash

risk. The first measure is the negative conditional skewness of firm-specific weekly returns over

the fiscal year (NCSKEW ), computed by taking the negative of the third central moment of

firm-specific weekly returns for each year and normalizing it by the sample variance of firm-

specific weekly returns raised to 3/2. The negative transformation creates a variable that

increases in value as the return distribution becomes increasingly negatively skewed. Therefore,

the higher the NCSKEW is, the higher is the likelihood of extreme firm-specific negative

5

outliers. Specifically, we compute NCSKEW for each firm i in fiscal year t as:

NCSKEWit = −n (n− 1)

32∑n

j=1

(Wijt −W it

)3(n− 1)(n− 2)

(∑nj=1

(Wijt −W it

)2) 32

(2)

where Wit is the firm-specific weekly return, W it is the average firm-specific return, and n is

the number of observations in fiscal year t.

Our second measure of crash risk is the down-to-up volatility measure (DUV OL) of the crash

likelihood. For each firm i over a fiscal year t, firm-specific weekly returns are separated into

two groups: “down” weeks when the returns are below the annual mean, and “up” weeks when

the returns are above the annual mean. The standard deviation for each of these subsamples is

calculated separately. For each firm i in fiscal year t, DUV OL is computed as the natural log

of the ratio of the standard deviation on down weeks to the standard deviation on up weeks:

DUV OLit = ln

[(nu − 1)

∑DOWN

(Wit −W it

)2(nd − 1)

∑UP

(Wit −W it

)2], (3)

where nd and nu are the number of down and up weeks, respectively. A larger value of DUV OL

suggests that the stock is more “crash-prone”.

Our third measure of stock price crash risk, CRASH, is based on the number of crash

weeks. A week is a crash week if the firm experiences a firm-specific weekly return that are 3.2

standard deviations below its mean. We define CRASH as a dummy variable equal to 1 if the

firm experiences at least one crash week during a fiscal year, and 0 otherwise.

2.3 Culture

As in Shao et al. (2013), we use the individualism index of Hofstede (2001) as the proxy for

national culture (IDV ) because this measure holds a dominant position in cross-cultural studies.

Individualism reflects the degree to which people in a country tend to have an independent,

rather than interdependent, self-construal. Individualistic values emphasize independence and

encourage the pursuit of individual achievements. A higher individualism score indicates a more

individualistic culture.

2.4 Control Variables

As in prior work, such as Chen et al. (2001), Hutton et al. (2009), and Kim et al. (2011b), we

construct the following firm-level variables, all measured in year t− 1 except ROA:

• DTURN : detrended turnover, defined as the difference between the average monthly

share turnover over the current fiscal-year period and the average monthly share turnover

over the previous fiscal-year period, where monthly share turnover is calculated as the

monthly trading volume divided by the total number of shares outstanding during the

month. DTURN is used as a proxy for investor belief heterogeneity (Chen et al., 2001).

• SIGMA: the standard deviation of firm-specific weekly returns over the fiscal-year period.

Chen et al. (2001) find that more volatile stocks are more likely to crash in the future.

• RET : the mean of firm-specific weekly returns over the fiscal-year period, times 100.

Chen et al. (2001) find that firms with high past returns are more likely to crash.

• MCAP : firm size, defined as the natural log of the market value of equity measured at

the end of fiscal year. Hutton et al. (2009) find that larger firms are more likely to crash.

• MTB: the ratio of the market value of equity to the book value of equity at the end of

fiscal year. Hutton et al. (2009) find that growth stocks are more crash-prone.

• LEV : financial leverage, calculated as the long-term debt divided by total assets at the

end of fiscal year. Hutton et al. (2009), for example, find that more leveraged firms are

more risky and crash-prone.

• ROA: return on assets, computed as the contemporaneous operating income divided by

lagged total assets. Hutton et al. (2009) and Kim et al. (2011b) find that firms with good

operating performance is less likely to crash.

• DISACC: the three-year moving sum of the absolute value of annual discretionary accru-

als, where discretionary accruals are estimated from the modified Jones model (Dechow

and Sloan, 1995). DISACC is used as a measure of the firm’s earnings management.

Hutton et al. (2009) find that opaque firms are more likely to crash.

• BIG4: A dummy variable equal to 1 if the firm is audited by a Top 4 auditor and 0

otherwise. We follow the literature on audit quality (e.g., Mark and Zhang, 2014) to use

BIG4 as a proxy for the transparency of the firm’s accounting statements. Dechow and

Sloan (1995) find that an increase in the transparency broadly reduces crash risk among

nonfinancial firms.

7

• NCSKEW : the negative skewness of past firm-specific returns, included to capture the

potential persistence of the third central moment (Kim et al., 2011b).

For the country-level variables, we follow Hu et al. (2015) and Shao et al. (2013) and use

the following control variables:

• Disclosure: a measure of the level of financial disclosure and availability of information

to investors, from Jin and Myers (2006), used to control for the country-level opacity.

• Anti−Self Dealing Index: anti-self-dealing index, a measure of country-level governance

from La Porta (1998).

• Rule of Law: the rule of law indicator of Kaufmann et al. (2011), included to capture

perceptions of the extent to which agents have confidence in and abide by the rules of

society, and in particular, the quality of contract enforcement, property rights, the police,

and the courts, as well as the likelihood of crime and violence.

• Creditor Rights: the creditor protection index of Djankov et al. (2007).

• GDP : the natural log of GDP per capita in U.S. dollars, which controls for a country’s

macroeconomic environments.

• GDPGrowth: the growth in a country’s GDP, which captures a country’s macroeconomic

conditions.

• Stock Market: the market capitalization of a country’s stock market scaled by its GDP,

used to control for a country’s stock market size.

2.5 Descriptive Statistics

We compute, for each year, mean cross-sectional crash risk measures and firm and country char-

acteristics for the period from 2000 to 2009. Table 1 shows the time-series summary statistics

on these cross-sectional averages. For crash risk, the average NCSKEW is −0.196 over our

sample period, the average DUV OL is −0.120, and the average CRASH is 0.115. The average

individualism score (IDV ) is 0.651 with a standard deviation of 0.239. On average, a firm in our

sample has a log market value of equity of 18.161, a market-to-book ratio of 2.069, a leverage

ratio of 24.3%, and an ROA of −13.0%.

3 Results and Discussion

3.1 Univariate Analysis

Figure 1 shows plots of country averages of crash risk measures against country individualism

scores. All three plots show a broadly positive association between crash risk and individualism.

[Insert Figure 1 about here]

Next, we split our sample into firms from high- versus low-individualism countries. We

classify a firm into the high- (low-) subsample if it is headquartered in a country whose individ-

ualism score is above (below) the cross-sectional median of the entire sample. Table 2 reports

the mean and median statistics on crash risk for these sub-samples, along with the tests for the

difference in means of crash risk between these groups. The difference in means of crash risk

between the high-IDV and low-IDV subsamples is positive and statistically significant across

all three crash risk measures, suggesting that crash risk is greater in the high-IDV subsample

than in the low-IDV one. This univariate result supports our hypothesis that individualism is

positively associated with stock price crash risk.

[Insert Table 2 about here]

Overall, the univariate analyses in this section provide support for a positive relation between

individualism and stock price crash risk.

3.2 Baseline Regressions

To examine the effect of individualism on stock price crash risk, we estimate the following model:

CrashRiskijt = α+ β1IDVj + γ′Controlijt−1 + ωk + φt + εijt, (4)

where i, j, k, and t denote firm, country, industry, and year, respectively. The dependent

variable, CrashRisk, refers to NCSKEW , DUV OL, or CRASH. Control is a vector of firm-

and country-level characteristics as discussed in Section 2.4, all measured in year t− 1, except

ROA. The regression is estimated by pooled OLS with industry and year fixed effects and

robust standard errors clustered at the firm level. Our independent variable of interest is the

9

country individualism score (IDV ). If β1 is positive and statistically significant, then we find

support for a positive effect of individualism on stock price crash risk.

[Insert Table 3 about here]

Table 3 reports the regression results for equation (4). In the regression of NCSKEW

on IDV and other control variables as shown in column 1, the coefficient on IDV is positive

and statistically significant at the 1% level, suggesting a positive effect of individualism on

stock price crash risk. A coefficient estimate of 0.128 on IDV indicates that stock price crash

risk increases by 12.8% for every 1 percentage point increase in the individualism index. This

result is economically significant. Columns 2 and 3 show the regression results for DUV OL

and CRASH, respectively. Similar results obtain as the coefficients on IDV are all positively

and strongly significant at the 1% level. As in the NCSKEW regression, the results are also

of economic significance.

Turning to the firm-level control variables, we see that the coefficient estimate of BIG4

is negative and significant as shown in columns 1 and 2, suggesting that firms with greater

transparency, captured by the use of Big 4 auditing firms for their accounting statements, are

associated with lower future stock price crash risk. DeFond et al. (2015) find that the increased

transparency broadly reduces crash risk among nonfinancial firms. Consistent with Hutton

et al. (2009), the coefficient on DISACC is significantly positive in all regressions, suggesting

that firms more likely to manage reported earnings are more likely to crash. For the remaining

control variables, the results are all consistent with prior work in the crash risk literature in

terms of sign and significance.

As for the country-level control variables, we find that firms domiciled in countries with more

transparent information environments, better creditor protection rights, more well-developed

stock markets, and higher GDP growth rates are less crash-prone.

3.3 Instrumental Variable Regressions

While the baseline results support our hypothesis that culture has a positive effect on crash

risk, we cannot rule out the possibility that our culture variable is endogenous, because time-

varying country and firm unobservables omitted from the regressions can be correlated with

both individualism and crash risk. To address this important concern, we use an instrumental

variable (IV) approach. Based on prior work, we use two sets of instruments as follows.

10

First, we follow Shao et al. (2013) and use three instruments, namely, (1) genetic distance

from the United States (Genetic Distance), (2) the license to drop pronouns (Pronoun Drop),

and (3) British Rule (British Rule). Genetic Distance, from Spolaore and Wacziarg (2009),

is the FST distance1 that measures a genetic distance from the United States. This measure

aggregates differences in the distribution of gene variants across populations, and thus captures

the degree of genealogical relatedness of different populations, which has been shown to be

highly correlated with individualism. Pronoun Drop, from Kashima and Kashima (1998), is a

dummy variable related to the requirement to use pronouns in a language (the license to drop

pronouns), which equals 1 if a country’s grammatical rules license person-indexing pronoun

drop and 0 otherwise. According to Kashima and Kashima (1998) and Shao et al. (2013),

Pronoun Drop is associated with the degree of psychological differentiation between the speaker

and the social context of speech and inversely correlated with individualism. British Rule is a

dummy variable equal to 1 if a country has historically been under the British rule (Treisman,

2000) and 0 otherwise. A colony of Britain should share some similarities in cultural values.

Shao et al. (2013) find that Pronoun Drop is highly correlated with individualism when British

Rule is incorporated.

To check the relevance of the instruments, in Panel A of Table 4 we present the first-stage

regressions, where we regress IDV on the instruments and the same set of independent variables

as in the baseline regressions. Column 1 shows that all the instruments have strongly significant

coefficients. The p-value of the F -test for the joint significance of instruments, shown at the

bottom of the panel, is close to 0, thus rejecting the null hypothesis of weak instruments. The

overidentification tests with p-value for both Sargan and Basmann statistics are all larger than

0.1 for all the crash risk measures (not reported for brevity), suggesting that the instruments

for individualism are valid. In addition, it is reasonable to assume that these instruments are

uncorrelated with stock price crash risk because there is no economic mechanism under which

the instruments affect stock price crash risk other than through culture.

Columns 2–4 show that the coefficient estimates on the fitted individualism (IDVFitted) are

all positive and significant at the 1% level (except for the NCSKEW regression), suggesting

1FST distance, also known as “coancestor coefficients”, is based on indices of heterozygosity, which refers tothe probability that two alleles at a given locus selected at random from two populations will be different (see,for example, Spolaore and Wacziarg, 2009):

FST is

{= 0 if the allele distributions are equal across the two population,

> 0 if otherwise.

11

that the positive effect of individualism on stock price crash risk is unlikely to be driven by

omitted unobservables.

[Insert Table 4 about here]

The second set of instruments that we use are based on Kwok and Solomon (2006) and

Li et al. (2013): religion (Religion), demography (Ethnic Fractionalization), and geography

(Geography). Religion, from La Porta (1998), is the percentage of people in the Protestant,

Roman Catholic, and Muslim religious faiths in 1980. Ethnic Fractionalization, from Alesina

et al. (2003), is measured as the degree of ethnic heterogeneity in a given country. We use the

continent of a country as a proxy for geography. According to Li et al. (2013), these variables

are selected as potential determinants of culture based on theory and data availability. Panel B

of Table 4 reports the two-stage least squares (2SLS) regression results. The regressions control

for firm- and country-level characteristics, as well as industry and year fixed effects.

Panel B of Table 4 reports the 2SLS regression results with this set of instruments. The

first-stage results show that the instruments are highly correlated with individualism. The null

hypothesis of weak instruments is strongly rejected at the 1% level, with p-value of the F -test

for the joint significance of the instruments close to 0. As before, the coefficient estimates of the

fitted IDV as shown in columns 2–4 are all positive and strongly significant at the 1% level,

which again suggests that our results on the positive effect of individualism on stock price crash

risk still hold.

3.4 Hierarchical Linear Regressions

A further issue is that our data can be viewed as multilevel data. At the country level, we have

firms from 36 countries. At the firm level, we have 19,080 firms. We therefore follow Li et al.

(2013) and Shao et al. (2013) to employ a hierarchical linear model (HLM) regression where

the set of firms within countries form the base-level observations while the countries serve as

the higher-level observations. The power of HLMs comes from their ability to correctly pool

firm-level effects across countries while also examining country-level relations.

We closely follow Li et al. (2013) in preparing the data for the HLM regression. First, we

center each country-level independent variable by its grand mean (averaged across countries)

so that every transformed variable has a mean of zero, and we add the suffix “−ctry” to each

of these variables. Second, we center each firm-level independent variable by its grand mean

(averaged across firms and countries for a given fiscal year), so that every transformed variable

has a mean of zero. Third, we create country-level mean values (averaged within a country)

on those grand-mean-centered variables in step 2 and add the suffix “−ctrymean” to each of

these variables. Finally, we create within-country residuals by taking the grand-mean adjusted

variables in step 2 and subtracting the corresponding within-country means in step 3. We name

these firm-level deviations separately from their corresponding country-level means by adding

the suffix “−firmdev”.

Table 5 presents the HLM regressions, all of which include industry and year fixed effects.

The coefficient estimates of IDV are all positive and strongly significant at the 1% level, sug-

gesting a positive effect of individualism on stock price crash risk. These results provide support

for the baseline results on the relationship between individualism and crash risk.

3.5 Additional Robustness Tests

To provide further robustness, we conduct several tests. First, we use alternative measures for

individualism because these proxies for culture can allay the concern that our baseline results

are only valid to the choice of a particular proxy. Following Chen et al. (2015), we use the

World Value Survey (WVS) on individualism as an alternative measure of individualism. An

advantage of using these data is that the measure is time-varying and thus mitigates a common

problem with time-invariability in country-level proxies for culture. The World Value Survey

covers 97 countries and is carried out in 7 waves, namely, 1981–1984, 1985–1988, 1989–1993,

1994–1998, 1999–2004, 2005–2009, and 2010–2014. We run the same regressions as in equation

(4) using the WVS individualism data for the periods 1999–2004, 2005–2009, and 2010–2014.

Since the WVS individualism index is time-varying, we are able to include country fixed effects

to control for any time-invariant country characteristics. Columns 1–3 in Panel A of Table 6

show the regressions with the alternative proxy for individualism, where we include country

fixed effects. As we can see, the coefficient estimate of the WVS individualism measure remains

positive and strongly significant at the 1% level, corroborating earlier results on the relation

between culture and crash risk.

[Insert Table 6 about here]

13

We also use an updated version of the individualism index as in Tang and Koveos (2008). To

allow for the updated components of cultural dimensions of Hofstede (2001), Tang and Koveos

(2008) establish a framework in which changes in economic conditions are the source of cultural

dynamics, while the endurance of institutional characteristics is the foundation for cultural

stability. A major advantage of Tang and Koveos (2008) is that they develop an integrated

empirical model to update Hofstede (2001)’s dimensions of culture, so that it provides a more

up-to-date and reliable reflection of each country’s true cultural predisposition. In columns

4–6 in Panel A of Table 6, we report the baseline regressions using Tang and Koveos (2008)’s

measure of individualism. Again, we find support for the positive effect of individualism on

stock price crash risk.

In the second test, we add more controls for country-level variables, such as additional

dimensions of cultures of Hofstede (2001) and country religion. Specifically, we include the power

distance scores (PDI), uncertainty avoidance (UAI), and masculinity scores (MAS). We use

the percentage of people in the Protestant (Protestantism), Roman Catholic (Catholicism), and

Muslim (Muslism) religious faiths in 1980 from La Porta (1998) as proxies for religion. Panel B

of Table 6 shows the same regressions as in equation 4 but with these additional controls. We

continue to find support for a positive effect of individualism on crash risk after controlling for

these variables.

To sum up, we show that the baseline regression results still hold under these robustness

tests.

4 Possible Mechanisms

After establishing a positive relation between culture and stock price crash risk, we now attempt

to identify possible mechanisms under which individualism positively affects crash risk. We

acknowledge that these underlying mechanisms are not necessarily mutually exclusive, and if

anything, may jointly contribute to this positive relation.

4.1 Trading by Overconfident Investors

First, traders from individualistic cultures are more overconfident because literature (e.g., Kag-

itcibasi, 1997; Markus and Kitayama, 1991) has shown that people from individualistic culture

tend to be more overconfident. For example, Chui et al. (2010) document the specific evidence

14

that individualism is directly linked to overconfident traders as it is highly correlated with

trading volume and volatility.

Second, overconfident investors’ trading activities can cause stock price crashes. The theo-

retical models of Odean (1998) and Daniel et al. (1998) show that overconfidence induces traders

to trade more aggressively even in the face of transaction costs and adverse expected payoffs.

In their models, overconfident traders place too much weight on their own views and too little

weight on other investors’ views when forming judgments about the value of a security. These

traders expect high profits from trading on their opinions, and their aggressive trading generates

excess volatility, which can lead to stock price crashes. Hong and Stein (2003) document that

investor belief heterogeneity, which is a form of trader overconfidence whereby each investor

irrationally thinks that his private signal is more precise than the others’, causes stock price

crashes.

These two streams of the literature suggest that overconfident investors’ trading activities

can be a channel through which individualism leads to stock price crashes. We thus argue that

if individualism induces overconfidence in investors whose trading activities causes stock price

crashes, then the positive effect of individualism on stock price crash risk should be stronger

when there are more overconfident traders in the market. To test this conjecture, we use

trading volume as a proxy for the presence of overconfident traders because behavioral finance

models predict higher trading volume in the presence of overconfident traders (e.g., Daniel and

Hirshleifer, 2015; Odean, 1998). We estimate the following regression model:

CrashRiskijt = α+ β1IDVj + β2IDVj ×OTit−1 + β3OTit−1 (5)

+ γ′Controlijt−1 + ωk + φt + εijt,

where i, j, k, and t denote firm, country, industry, and year, respectively. OT proxies for the

presence of overconfident traders in the markets and is measured by trading volume. All the

other variables are the same as in equation (4). The regression is estimated by pooled OLS

with industry and year fixed effects and robust standard errors clustered at the firm level. Our

interest is in the coefficient estimates of IDV (β1) and the interaction term IDV ×DTURN

(β2). If these coefficients are positive and statistically significant, then we find support for the

hypothesis that the positive relation between individualism and stock price crash risk is stronger

in the presence of overconfident traders.

15

[Insert Table 7 about here]

Table 7 reports the results for the regression equation (5). Columns 1–3 show that the

coefficient estimates of both IDV and IDV ×DTURN are positive and statistically significant

regardless of which measure of crash risk is used, suggesting that the positive effect of individ-

ualism on stock price crash risk is more pronounced for higher trading volume stocks. These

results lend support to our hypothesis that the positive effect of individualism on stock price

crash risk arises from trading activities of investors whose overconfidence is fostered by their

individualistic cultures.

4.2 Bad-news Hoarding by Overconfident Managers

The positive effect of individualism on stock price crash risk may also stem from bad news

hoarding behavior of overconfident managers.

Literature shows that managers from individualistic cultures are more overconfident be-

cause people in more individualistic cultures are generally more overconfident (e.g., Kagitcibasi,

1997; Markus and Kitayama, 1991). Ferris et al. (2013) observe that although an interna-

tional phenomenon, overconfidence is most commonly observed in individuals who head firms

headquartered in Christian countries that encourage individualism, because managers in these

individualistic cultures are more likely to undertake complex acquisitions.

Overconfident managers often engage in bad-news hoarding behavior, which can cause crash

risk. Overconfident managers’ bad-news hoarding may occur in different ways. Ahmed and

Duellman (2013) find that overconfident managers tend to delay loss recognition, a form of bad-

news hoarding. Overconfident managers tend to overestimate the returns to their investment

projects (e.g., Heaton, 2002; Malmendier and Tate, 2005, 2008; Malmendier et al., 2011), and,

thus, misperceive poorly performing negative net present value (NPV) projects as positive NPV

projects, leading to delayed loss recognition. Schrand and Zechman (2012) find that earnings

misstatements, another form of bad-news hoarding, are largely a result of managerial overcon-

fidence because managers are overoptimistic about their firms’ future performance. Hribar and

Yang (2016) find that overconfident managers are more likely to issue overly optimistic earnings

forecasts and are more likely to have earnings that miss such forecasts. Taken together, these

studies suggest that bad news hoarded by overconfident managers can be accumulated, which

makes their firms’ stock prices more likely to crash. Indeed, Kim et al. (2016) find that U.S.

16

firms with overconfident managers are associated with higher stock price crash risk compared

with firms run by nonoverconfident ones.

In the spirit of this discussion, we argue that if individualism instills overconfidence in

managers, who often engage in bad-news hoarding activities that could eventually lead to stock

price crashes, then the positive effect of individualism on stock price crash risk should be

stronger in firms run by overconfident managers. To test this hypothesis, we follow Schrand

and Zechman (2012) and Ahmed and Duellman (2013) and use several investment-based proxies

for overconfident managers, namely, overinvestment and risky investments. These proxies are

based on the findings that firms with overconfident CEOs have larger capital expenditures and

tend to overinvest in capital projects (e.g., Malmendier and Tate, 2005). The first proxy of

managerial overconfidence is the amount of excess investment in assets from the residual of

a regression of total asset growth on sales growth run by industry-year (OV ERINV EST ).

OV ERINV EST equals 1 if the residual from the excess investment regression is greater than

0, and 0 otherwise. Intuitively, if assets are growing at a faster rate than sales, then it suggests

that managers are overinvesting in their company relative to their peers. The second measure

(CAPEX) is a dichotomous variable, equal to 1 if the firm’s capital expenditures deflated by

lagged total assets in a given year is greater than the median capital expenditures scaled by

lagged total assets in the same year for the industry where the firm belongs, and 0 otherwise.

Since Hirshleifer et al. (2012) find that overconfident managers prefer corporate risk-taking, we

use research and development expenses as a percentage of total assets (R&D) as another proxy

for overconfident mangers.

To examine whether managerial bad-news hoarding is a plausible channel through which

individualism has a positive effect on stock price crash risk, we estimate the following model:

CrashRiskijt = α+ β1IDVj + β2IDVj ×OMit−1 + β3OMit−1 (6)

+ γ′Controlijt−1 + ωk + φt + εijt,

where i, j, k, and t denote firm, country, industry, and year, respectively. OM indicates

the presence of overconfident managers and is proxied by overinvestment (OV ERINV EST ),

capital expenditure (CAPEX), or research and development to total assets (R&D). All the

other variables are the same as in equation (4). We estimate the regressions with the pooled

OLS, where we include industry and year fixed effects and use robust standard errors clustered

17

at the firm level. Our interest is in the coefficient estimates of IDV (β1) and the interaction

term, IDV ×DTURN (β2).

[Insert Table 8 about here]

Table 8 reports the results for the regression equation (6). Columns 1–9 show that the

positive effect of individualism on stock price crash risk is more pronounced in firms with

overinvestment and risky investment because the coefficient estimates of both IDV and IDV ×

OM are positive and strongly significant at the 1% level in all model specifications, regardless

of which measure is used for OM . These results support our hypothesis that bad-news hoarding

activities by managers, whose overconfidence is fostered by their individualistic cultures, cause

stock price crashes.

5 Conclusion

We examine the effect of national culture on stock price crash risk, a currently unexplored

question in the literature. We find that individualism has a positive effect on stock price

crash risk, which suggests that firms headquartered in individualistic countries are associated

with higher stock price crash risk. We also find that this positive effect becomes stronger for

firms with high trading volume, overinvestment, and risky investments. Our results suggest

that individualistic cultures encourage overconfident managers’ bad-news hoarding activities,

and overconfident investors’ aggressive trading behavior, which eventually can lead stock price

crashes. This is the first study to document national culture as a potential factor contributing

to stock price crash risk.

Table 2: Univariate Results

This table reports the univariate results on the tests of differences in means and medians for the stockprice crash risk measures between two groups of firms formed on country-level individualism indexduring the sample period from 2000 to 2009. For each year, sample firms are assigned into either“low-individualism” or “high-individualism” groups based on the individualism index of their countries.The High-Individualism group consists of firms domiciled in countries whose individualism scores areabove the cross-sectional median score; the Low-Individualism group contains firms from countries whoseindividualism scores are below the cross-sectional median score. Variables are defined in Appendix 1.

Table 3: Baseline Regression Results

This table reports the pooled OLS regressions of stock price crash risk on individualism and othercontrol variables. The dependent variable is one of NCSKEW , DUV OL, and CRASH. The variableof interest is the individualism index (IDV ). Variables are defined in Appendix 1. Robust t-statisticsin parentheses are computed using standard errors clustered at the firm level. *, **, and *** denotestatistical significance at the 10%, 5%, and 1% levels, respectively.
