Presenter
Presentation Notes
At last year's CEA's, when Jean-Yes Duclos asks to deliver a state of the art address on the gender gap gap, little did he know at the time that he would become part of the first gender neutral cabinet, as Minister of Families, Children and Social Development

Earnings Inequality in Top Incomes

Presenter
Presentation Notes
Now the other important theme of this talk "earnings inequality in top incomes" has also become a hot political issue. Thanks to Bernie Sanders for picking up and graphically enhancing numbers for the work of Emmanual Saez and co-authors.

Earnings Inequality in Top Incomes

6Source: Veall (2012)

Presenter
Presentation Notes
(Slide 6 ) Indeed his Canadian co-author, Mike Veall made the topic of increasing inequality in top incomes the topic of is very successful presidential address in 2012. Although increases in the income share of the top 1% in Canada are lower than in the United States, they are nevertheless quite dramatic: the income share going to the top 1% was greater than 12% in 2010.

Increasing Earnings Inequality in Top Incomes and the Gender Pay Gap

• Apply the approach used in the analysis of earnings inequality in top incomes (developed by Thomas Piketty, Emmanuel Saez, and co-authors), as well as reweighing techniques à la DiNardo, Fortin and Lemieux (1996) [DFL] to the analysis of the gender pay gap

• Use all earnings data from the Canadian Longitudinal Worker Files (LWF, 1983-2010) supplemented by hourly wage data from the Labour Force Survey (LFS, 1997-2015)– Because couples file their income taxes separately, all earnings for T4

returns are available separately by gender in Canada

7

Presenter
Presentation Notes
So in the lecture today I'm gonna apply the approach use for the analysis of earnings inequality in top incomes, as well as reweighting techniques developped in DFL, to the analysis of the gender gap. To consider the earnings in top incomes we will appeal to Canadian longitudinal worker files, the LWF, but we will supplement with an analysis of the hourly wage data from more commonly used labour force survey

Increasing Earnings Inequality in Top Incomes and the Gender Pay Gap

• Questions of interest:1) What are the consequences of the under-representation of women in top

jobs for the overall gender pay gap?2) How is it contributing to the slowdown in the convergence of

female/male pay?3) What public policies and firm practices are effective to improve this

under-representation?

Presenter
Presentation Notes
I will focus on a few questions of interest: first what are the consequences of the under-representation of women in top jobs to the overall gender pay gap, second is this a factor in the slowdown of the convergence of male and female pay and third what kind of policies and firm practices would be effective to improve this under representation

Canadian DataLongitudinal Worker File (LWF)• LWF is a 10% random sample of all

Canadian workers• Years: 1983-2010• integrates data from the T1 and T4

files of Canada (CRA) and the LEAP (Statistics Canada)

• Annual earnings from all jobs, include bonuses, honorariums, etc.

• Selected if > half of minimum wage earnings equivalent

• Select workers age 25 to 64

Labour Force Survey (LFS) Public Use

• Monthly survey on approximately 100,000 individuals rotating 6-months panel sample design

• Years: 1997-2015• Hourly wage of employees from

main job• Selected if > half the minimum

Presenter
Presentation Notes
Let me begin by giving you some details about the data that we will be using The longitudinal worker file that we are using is 10% random sample of all Canadian workers. We have access to the years 1983 to 2010 and the earnings data come from T1 and T4 slips therefore we have annual earnings from all jobs including bonuses. This contrasts with more traditional data sources used to study the gender gap which focuses on hourly wages on the main job, so there will be a bit of thinking outside the box. We select workers age 25 to 64 to avoid issues with students.

Labour Force Survey (LFS) Public Use

Presenter
Presentation Notes
The important disadvantage of the LWF is the absence of labour supply information, that being said even in the labor force survey the number of weeks work is unavailable. But an important limitation of the LFS survey is the fact that earnings or wage data is top coded percentile 99.9 but it has a wider set of the covariates that we take advantage off. Whereas in the LWF, we are only using industry at this point. All data are inflation adjusted using the CPI and in 2010 Canadian dollars.

Presenter
Presentation Notes
To be sure that we are on the same page, I will begin by showing recent trends in different dimensions of gender gap issues First, we will look at the evolution of labour force participation, next at the evolution of wages differentials, and then I will focus on differences in the top percentiles and for the analysis, I will consider different sets of counterfactuals.

Presentation Notes
The steep growth of women's labour force participation in the mid 20th century has been replaced in the 2000s by a substantial leveling-off, but nevertheless in Canada there has substantial convergence in labour force participation with male and female differences standing in the single digit.

Presenter
Presentation Notes
This contrasts with the experience of thea U.S. where there has been actually a declining in participation for both genders following the great recession. The longer perspective in the U.S. graph (it starts in 1947) reminds us that this process of growth in female labor force participation has been longstanding with a long list of causes, including the introduction of washing machines.

The Women’s Liberation Movement of the 1960s and The “Pill”

• Goldin and Katz (2002) and Bailey (2006) point out to important changes in women’s LFP occurring in the 1960’s

• Women born after the mid-1950s had access to reliable contraception• More likely to pursue higher education and enter life-long careers• Accompanied by a decline in traditional gender roles attitudes which

stabilized in the mid-1990s in the U.S. (Fortin, 2015)• Before married women were more likely `secondary workers’ who entered

the labour market when kids were in school • Mulligan and Rubinstein (2013) argue that the closing of the gender pay

gap is largely due to changing selection of women into the labour market

14

Presenter
Presentation Notes
Nevertheless many think that the women's liberation movement of the sixties presented a shift in woman's attachment to the labor market, with many women switching from being secondary workers to career women.

This implies that there are clear generational effects in the growth of female labour participation. The figure shows pre-Pill cohorts in the warmer colors, but later baby boomers in reens, and the generation Y in blue. As the pre-Pill cohorts reach retirement age, much of the growth in FLP coming from generational effects has been exhausted.

Presentation Notes
This is perhaps more clearly seen when we contrast the life-cycle pattern of LFP of women born in the early forties with those born in early sixties. For the early forties women, there is a clear hump shape of participation reaching its around 45 years old. Whereas for those born in the early sixties, their pattern of LFP is much more constant over the life-cycle with perhaps a small drop of the peak of childbearing years.

Continued Gender Convergence?

• According to the Mincer-Polachek hypothesis (1974), gender differences in experience and labour force attachment are the key determinants of the gender wage gap.

• Blau and Kahn (2016) found that declining gender differences in experience in the United States accounted for 18-31 % of wage convergence between men and women over the 1980-2000 period.

• Going forward, Goldin (2014) suggested that the impact of work force interruptions for family responsibilities should be understood in the context of temporal flexibility (or the lack thereof) in impacting the gender wage gap.

17

Presenter
Presentation Notes
This shift in labour force attachment was that the origin of the Mincer-Polachek hypothesis where it was believed that as gender differences in labour market experience would decrease with more women adopting male life-cycle patterns of LFP, but so would the gender pay gap. Indeed Blaud and Kahn in a recent paper and found that these declines in gender differences labor market experience do account for a sizable part of the convergence between men and women's wages. More recently, Claudia Goldin has suggested that gender differences in labour force attachment have to be understood in the context of temporal flexibility.

Presentation Notes
This implies that more atttention has to be paid to gender differences in hours of work. As this graph shows focusing only on those with positive hours, even for younger cohorts there is substantially less convergence between men and women in LFP at the intensive marging. The gender ratio in hours of work stands around 85%.

Gender Gap in Hours andIncreasing Earnings Inequality in Top Incomes

• Kuhn and Lozano (2008) had shown increases in long hours of work (>48 hours a week) among highly educated highly-paid older men was greatest in detailed occupations and industries with larger increases in residual wage inequality.

• Pointing to some high penalty for flexibility in some high wage occupations, Goldin (2014) further conjectures that rewards to working long hours are an obstacle for the gender gap in pay to vanish

• Cortes and Pan (2015) find that highly competitive jobs (O*NET characteristics) also have long hours

• Cortes and Pan (2016) find that across countries long hours lowers the share of married women in corresponding occupations

19

Presenter
Presentation Notes
Now the link between long hours of work and increasing inequality was first noted by Kuhn and Lozano for men. More recently Claudia Goldin has argued that rewards to working long hours presented another obstacle for further progress in the gender pay gap. Further, Cortes and Pan has found a link between highly competitive jobs, long hours, and the share of married women in such occupations.

Trends

1) Evolution of female/male labour force participationa) Extensive margin (LFP) : substantial convergenceb) Intensive margin (hours of work): less convergence

2) Evolution of female/male “raw” wage and earnings ratios: Continuing progress?

3) Evolution of female shares across top percentiles of the overall distribution of wage and earnings

4) Counterfactuals with alternative simulations

20

Presenter
Presentation Notes
To recap what we have seen so far. We have seen substantial convergence in male and female labour participation at the extensive margin, less so at the intensive margin. The next question is to what extent this has lead to converging in male and female pay. Do we have continuing progress?

What is the ratio of women’s to men’s earnings on average in Canada?

Source: Drolet (2011) 25 to 54 year olds, various data sources.21

Presenter
Presentation Notes
Before talking about the gender pay gap, it is important to see how the basis of computation has a large impact on the actual numbers. When computed on hourly wages for all workers, the gender ratio hovers around 85%; when we include the annual earnings of full-time workers we are more around 70%, and then when we use the annual earnings of all workers we are down to 65%.
Page 22: Gender Pay Gap - Faculty and Staff | Faculty of Artsfaculty.arts.ubc.ca/nfortin/Fortin... · 2016-06-07 · Earnings Inequality and the Gender Pay Gap Nicole Fortin Vancouver School

What is the ratio of women’s to men’s earnings on average in Canada?

• “Hourly Wage” ratio ≈ 85% is the preferred measure to consider whether employers treat women fairly and should be used in statements such as

“women earn 85 cents out of every $1 men earn”• “Annual Earnings” ratio ≈ 65% mixes the number of hours worked with

how much is earned by hour provides a better measure of the welfare of women

• More women work part-time, many women working full-time full-year work less hours a week than men (clerical vs. industrial workers)

• But the “All Annual Earnings” measure is the only one available for the very top income groups

22

Presenter
Presentation Notes
When we are considering issues of fairness, do employers treat men and women the same, the hourly wage ratio is the preferred measure. This is because the annual earnings ratio mixes the number of hours worked with which how much is earned by the hours. On the other hand, it does provide a better measure of the welfare of women and importantly for our exercise today, this annual earnings measure is the only one available for the very top income groups.
Page 23: Gender Pay Gap - Faculty and Staff | Faculty of Artsfaculty.arts.ubc.ca/nfortin/Fortin... · 2016-06-07 · Earnings Inequality and the Gender Pay Gap Nicole Fortin Vancouver School

What is the ratio of women’s to men’s earnings on average in Canada?

• The focus of all annual earnings can also be justified by the less favorable gender earnings ratios found by Frenette (2014) over the life-cycle

• In terms of the present value of total cumulative earnings (1991-2000) from the LWF (combined with the 1991 Census), they are even lower

PV Cumulative Earnings ratio ≈ 57% for university graduates and college graduates, ≈ 53% for high school graduates

23

Presenter
Presentation Notes
More recently, Frenette showed that in terms of the cumulative earnings ratio is where getting dangerously close to 50% range.

Presentation Notes
Considering generational effects again, we see that for all cohorts (the black line) there as indeed been progress the gender ratio in hourly wages moving from about 80 in 1997 to about 85 in 2010. However when we look the path for generation Y, we see more of a flat line if not a declining line. Therefore part of the overall progress is due to their retirement of those pre-Baby Boom cohorts, whose larger gender pay gap can be partly explained by lower level of experience. We see much less progress for the younger cohorts.

Standard Decomposition of the Gender Pay Gap

• The Oaxaca-Blinder decomposition starts with gender-specific OLS regressions of individual characteristics on (log) wages:

𝑌𝑌𝑔𝑔 = 𝑋𝑋𝑔𝑔′𝛽𝛽𝑔𝑔 + 𝜀𝜀𝑔𝑔, g = m, f• Constructs a counterfactual wage such as “what would be the average

wage of women if they had the same characteristics as men” 𝑌𝑌𝑓𝑓𝑚𝑚 = 𝑋𝑋𝑚𝑚′ 𝛽𝛽𝑓𝑓 = 𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑞𝑚𝑚 × 𝑝𝑝𝑝𝑝𝑞𝑞𝑝𝑝𝑞𝑞𝑓𝑓

• Divides the average gender pay gap into “explained” and “unexplained” part �𝑌𝑌𝑚𝑚 − �𝑌𝑌𝑓𝑓 = (𝑌𝑌𝑓𝑓𝑚𝑚 − �𝑌𝑌𝑓𝑓) + (�𝑌𝑌𝑚𝑚−𝑌𝑌𝑓𝑓𝑚𝑚) = ( 𝑋𝑋𝑚𝑚′ − 𝑋𝑋𝑓𝑓′)𝛽𝛽𝑓𝑓+ 𝑋𝑋𝑚𝑚′ (𝛽𝛽𝑚𝑚 − 𝛽𝛽𝑓𝑓)

explained unexplained

Presenter
Presentation Notes
So far we have considered in the "raw" gender gap, but what about the adjusted gap, that is the gap adjusted for differences gender differences in characteristics. The traditional Oaxaca-Blinder decomposition starts by constructing a counterfactual wage. The one that we emphasize here is "what would be the average wage of women be if they have the same characteristics as men" it corresponds to a situation where women would have been improving their characteristics such as educational attainment. It is computed as male quantities evaluated at the female prices. Using this counterfactual wage, the standard decomposition divides the difference in male and female wages into the differences in average male and female characteristics evaluated valued at female prices: this corresponds to the explained component of the gender gap while the differences in male and female returns evaluated at the male average characteristics correspond to the unexplained part.
Page 28: Gender Pay Gap - Faculty and Staff | Faculty of Artsfaculty.arts.ubc.ca/nfortin/Fortin... · 2016-06-07 · Earnings Inequality and the Gender Pay Gap Nicole Fortin Vancouver School

Gender Pay Gap Largely “Unexplained” by Human Capital Variables

• For the United States, Blau and Kahn (2016) using human capital variables, including actual experience from the PSID, find a notable decline in the unexplained gap—from 0.341 log points in 1980 to 0.197 log points in 2010.

• But as a share of the gender gap in both years, the unexplained portion is actually a larger share of gap in 2010 (85%) than in 1980 (71%).

• For Canada, Baker and Drolet (2010) also report some progress in the unexplained gap from 0.163 log points in 1981 to 0.141 log points in 2008.

• But this represents an increase, from 1981 (61%) to 2008 (85%), in the share of gap that is unexplained by education, occupation and industry.

Presentation Notes
What is a source of concern in this decomposition is the unexplained part, that is, the part that arises from differences in the wage structure that men and women face. Blau and Kahn in a recent paper haveI found using human capital variables, that include actual experience, that there has been a declining in the unexplained gap. However as a share of the gender gap, they find that the unexplained portion is actually increasing over time, 85% in 2010. For Canada, Baker and Drolet report results along the same line; they also find that the share of the gap that remains unexplained by education, occupation, and industry is also around 85% in 2008.

They argue that this is because over time education in particular has become a countervailing explanatory variable, that is women should be paid more give in the higher level of education.

Gender Pay Gap Largely “Unexplained” by Human Capital Variables

• Baker and Drolet (2010) explain that in many dimensions, such as education, women increasingly have an advantage over men.

• But because women’s wages have not seen commensurate increases, these are countervailing factors to explain the gap.

• They argue that most significant exception to this is the industrialdistribution of employment in which men maintain a significant advantage.

30

Presenter
Presentation Notes
They also argue that the industrial distribution of employment, remains all one of the characteristic in which men maintain a significant advantage.

Industry Composition Largest Single Explanatory Factor* in the Private Sector

• Yet, Schirle(2015) finds that in most provinces more than half of the gap is unexplained

Indeed, Schirle who considered the gender gap at the provincial level, found that in 2014 industrial composition was the largest single explanatory factor. However most provinces a very substantial share the gap remained unexplained.

Trends

1) Evolution of female/male labour force participationa) Extensive margin (LFP)b) Intensive margin (hours of work)

2) Evolution of female/male average wage and earnings ratios: Slower progress in recent years, share of the gap unexplained has increased, industry may remain a potent explanatory variable

3) Evolution of female shares across top percentiles of the overall distribution of wage and earnings

4) Counterfactuals with alternative simulations

Presenter
Presentation Notes
To summarize what we've seen in terms of the gender gap: we found a slowdown in the decline of the gender gap, an increase in the share of the gender gap there remains unexplained, although industrial composition may still have the explanatory power.

Increasing Earnings Inequality and the Gender Pay Gap

• When residual inequality experienced stupendous increases in the 1980s, Blau and Kahn (1997) coined the term “swimming upstream” to characterize women’s pursuit of pay equality in the face of countervailing currents.

• Have recent increases in top incomes lead to similar effects, therefore accounting for the slower progress in the gender pay and growing unexplained (by traditional factors) share?

• To the extent that some of the increases in top incomes are associated with excesses in rent seeking, curtailing those excesses would slow the countervailing currents

33

Presenter
Presentation Notes
We now turn to increasing top income inequality as the potential explanatory factor for this slower progress and growing unexplained share. It is important to mention that when residual inequality were increasing stupendously in the 1980s, Blau and Kahn coined the term "swimming upstream" to characterize women's pursuit of pay equality in the face of this countervailing current. So what we're asking is whether the recent increases in top income inequality could be leading to similar countervailing effects. Naturally we could also question the sources of the stunning increases in top incomes and ask whether all these countervailing currents can be slowdown.

Gender Gap in Top Incomes

• Follow Guvenen, Kaplan, and Song (2014) in using the thresholds of the wage and earnings distribution for men and women combined

• Depart from the traditional literature on the glass ceiling which compares the pay gap at percentiles of the gender-specific distributions

• Depart from most of the literature which uses the logarithm of wages or earnings in order to emphasize the top end

• Allow for the construction of counterfactuals to study the under-representation of women in top income groups

• Study the role of industrial segregation within income groups

36

Presenter
Presentation Notes
We will follow a similar methodology to the one of Guvenen, Kaplan and Song who use thresholds of the wage and earnings distribution of men and women combined. So in that way, we're doing now departed significantly from the traditional literature looking at the glass ceiling effect which usually compares the pay gap at percentiles of the gender-specific distribution. We will depart from the traditional literature use the logarithm of wages and use levels instead. This is needed in order to emphasize the top-end rather then using the logarithm which compress the top end. We construct counterfactual that will simulate alternative representation of women in top income groups and we will also study the impact of industrial segregation.

Presentation Notes
We use the following 3 thresholds for top income earners: the top 10%, the top 1%, and the top 0.1%. Now because of a lower top coding in the LFS, because of bonuses, because of all longer hours in top jobs, the annualized LFS thresholds do not correspond the LWF thresholds. So you should think of the thresholds for the different data source at quite different.

This is best illustrated by showing the evolution of shares of women in our four income groups. In the LFS, among the bottom 90% women comprise more than 50% of workers. whereas let's say in the top are in the next 9%, they make up less than 40% of workers. Even though there's been substantial increases over the period, in 2015 women represent less than 20% of the top 0.1% (in the LFS, these are workers making more than $130,000 in 2010).

Presenter
Presentation Notes
In these large samples, we will construct these counterfactuals using reweighting. It is important to note that Pat Kline has explicited shown the that our counterfactual of choice, the average earnings of women if they had the male characteristics, can be computed either from a regression framework as in Oaxaca-Blinder or using DFL reweighting, where the idea is to replace the female weights by the male weights in the computation of the average. This correspondence is a valid under the common support and the conditional independence assumption. I raise the commons support assumption, because it can indeed became an issue in some of our top income groups.

• So that reweighing observations requires only the ratio of shares in each j-category: 𝑤𝑤(𝑋𝑋𝑖𝑖𝑗𝑗)=𝑁𝑁0

𝑁𝑁1∗ 𝑁𝑁1𝑗𝑗𝑁𝑁0𝑗𝑗

where 𝑆𝑆1𝑗𝑗 is the share of group 1 in category j • With conditional means, the overall mean is �𝑌𝑌0=∑𝑖𝑖 𝑆𝑆0𝑗𝑗𝑌𝑌0𝑗𝑗, so that

Presentation Notes
Translating of these population means formulas in sample analogs, we get the weights will correspond to the ratio of male share over female shares in the case of category-j of a categorical variable. In our case, the categorical of the variable of interest will be our 4 percentile groupings, as well as industry. Once we have computed the categorical means, for example the male categorical means, all we have to do to obtain our counterfactual is to multiply by the female shares .

If the proportion of women across professorial ranks was identical to men, the overall counterfactual average female salary would be:

51.8/100×146048 + 30.7/100×114595 + 17.6/100×99709 =128259.3, and the overall ratio would be 128382/134955(*100)=95% The salary gap explained by rank is 128259.3-120623.1 =7636.2 More that 53% of the gap is accounted for by the gender differences in the proportion of

Presentation Notes
Let me give you an example that will be on familiar, that is one that uses of the salaries of professors, and even close to home the case of professors at UBC are in 2010. The overall female-male ratio was of a less than 90%, whereas the gender ratio in each professioriall rank, that is among Full, Associate, and Assistant Professors was closer to 95%. The proportion of male and female across the ranks was very different with 52% of men in the Full category vs. 31% of women, and correspondingly higher proportion of women at the Assistant level. So if we simply multiply the average female salary by the male shares, we obtain the average counterfactual salary that women would have earned if they weren't distributed across ranks as men are. Now this leads to an overall ratio of 95% and an explained gap of more than $7000 or 53 percent of the gap.

The more complete specification accounts for 80% of the gap, 46% of which from vertical segregation and 22% from horizontal segregation.

This leaves an unexplained gender gap of 2.2% of average professorial salary

Presenter
Presentation Notes
Now how does this measure of vertical segregation compares with other measures for example of horizontal segregation are captured by departmental dummies. We can turn to the familiar OB decomposition and we find that professorial rank still explain 46% of the gap while departmental dummies accoutn for 22% of gap. So it is a quite successful decomposition, with only 20% of the gap remaining unexplained.

(Slide 52) When we apply the same reweighting techniques to the average of all the annual earnings from the LWF, we find that the gender ratio would be almost 20 points lower if women had the same distribution across for all four percentiles groupings as men. Interestingly, this correspond to a growing portion of the gap. For example in 2010, 58% of the 33 percentage points gap would be explained by this measure of vertical segregation.

Now for the LFS, we can conduct a full O-B decomposition and compare the impact of the under-representation of women in top centiles to standard explanatory variables. Here we find that even after controlling for education, union coverage, industry and occupation that the percentile groupings explaining a growing share of the gap, that is 37% in 2015 vs. 19% in 1997. Industry has become the second leading explanatory factor. Also notice the negative a coefficients on education and tenure showing that these human capital variables have become true countervailing factors.

Impact of Under-Representation in Top Jobs

• Over time, the under-representation of women in top jobs accounts for a growing share of the gender gap from 19% in 1997 to 37% in 2015, after accounting for the usual list of

factors (education, occupation, industry, etc.)• Even against industry and occupation, it is the most significantly

explanatory factor • It substantially reduces the unexplained portion of the gender gap which

had been growing over time in a puzzling way.

Let me now turn to our second counterfactual as exercise where we ask how women would fare if they had the same industrial distribution as men. One way to understand how men and women are distributed differently across industry is to think of women are being well-represented in Service Industries, with Health Care being the one where they really dominate, followed by the Education Sector, while men really dominate in the primary and secondary sectors, as well as in the manufacturing and distribution sectors.

Among the top earners, the distribution of men and women is quite similar as for the overall. With a substantial concentration of men in the top 0.1% in the Manufacturing sector and women in the top 0.1% in the Education and other Services sectors and a quasi- absence in topin the and primaries and resources extraction Sectors. However they have been substantial important changes from our early 1997 to 2002 period to the last five years.

In more recent years, they have been a clear shift of men in the top jobs from the manufacturing sectors to the extractive resource sector. There have also been important shifts of women in top jobs away from education and into a more diverse set of industrial sectors, in particular the distribution sector.

So when we ask within each percentile grouping "what if women worked in the same industrial sectors such as men" we find well that for women in the bottom 90%, and thus the overall, this would have implied a less favorable gender ratio.

Again removing the top centiles all for which we have common support issues, we find are less favorable gender gap for the bottom and for the top which are is almost reaching parity.
Page 63: Gender Pay Gap - Faculty and Staff | Faculty of Artsfaculty.arts.ubc.ca/nfortin/Fortin... · 2016-06-07 · Earnings Inequality and the Gender Pay Gap Nicole Fortin Vancouver School

Impact of Industrial Composition

• Although issues of common support limit the analysis for the top 1% and 0.1%, overall women’s own choice of industrial sectors seem appropriate

• Among the top 9%-1%, women would almost reach parity if they works in the same industrial sectors as men, but in the bottom 90% would do worse

• Largely due to the health care sector, which is a well-paying sector in the bottom 90%, but less so in the next 9% (among the salaried workers we observe)

• It could be arguably different if we included self-employment income

63

Presenter
Presentation Notes
We looked a little more closely at which industrial sectors were the source of the effect. Unlike education, the countervailing effects comes from differences in returns across percentiles groupings. Essentially when you're in the bottom 90% for women, the healthcare sectors is relatively well-paying sector. However for those in the next 9%, it is not relatively less well-paying, especially given that we observed only salaried workers. For example, we are missing the business earnings of doctors.

Bottom-Line

• Looking back at the transformation of women’s work in Canada over the 20th century, Fortin and Huberman (2002) had argued that the decline in vertical segregation had contributed more to the improvement of women’s labour market outcomes than changes in horizontal segregation.

• With increasing earnings inequality in top incomes, further improvements in vertical segregation, “more women in top jobs” will be likely be even more important for further decline in the gender pay gap in the 21st

century• But unlike in the 20th century, further educational attainment alone will

not yield those changes!

64

Presenter
Presentation Notes
So the bottom line: Does increasing inequality in top income contribute to the slowdown of progress in the gender gap and the answer is Yes, it does. Indeed, it contributed to a growing share of the gap falling into the unexplained category, that is unexplained by the usual factors. We conjecture that further decline in the gender gap in the 21st century will have to come from "more women in top jobs". So the next question is what are the best policies and firm practices that can facilitate an increased representation of women in top jobs.
Page 65: Gender Pay Gap - Faculty and Staff | Faculty of Artsfaculty.arts.ubc.ca/nfortin/Fortin... · 2016-06-07 · Earnings Inequality and the Gender Pay Gap Nicole Fortin Vancouver School

Public Policy and Gender Pay Differentials

• Gender pay differentials “within” occupation “Equal Pay for Equal Work” • Gender pay differentials across “comparable” occupations, resulting from

horizontal segregation, are the focus of “Pay Equity” policies, implemented in the private sector of Canada’s two

most populous provinces: Ontario (1996) and Quebec (2001)• Gender pay differentials arising from the potential obstacles that women

face climbing (or not) the job ladder (vertical segregation) “Employment Equity”, enacted in the Federal jurisdiction in principle could

address disparities across the job ladder.

65

Presenter
Presentation Notes
The existing policies to foster gender equality in the workplace are unlikely to be very helpful. "Equal Pay for Equal Work" is within-occupation policy, "Pay Equity" work across comparable occupations in an horizontal fashion. Only "Employment Equity" is directed at vertical segregation, but its coverage is relatively narrow, and has focused in recent years on issues of ethnic and racial diversity, and disability.

More Women in Tops Jobs! What to Do?

• In recent years, many countries have pushed for more general gender equality in decision-making with bolder moves. Both in the political sphere and on corporate boards.

• Many European countries implemented female quotas on the board of directors of firms on public stock exchanges.

• Some emerging countries are doing the same.

More Women in Tops Jobs! What to Do?

• Short of calling for gender quotas, the Canadian Securities Administrators of seven provinces and territories (CSA, 2015) implemented “comply-or-explain” female representation rules on January 1, 2015 (Shecter, 2014; McFarland, 2015).

• These rules require companies listed on their stock exchanges to disclose how many women they have on their boards and in their executive ranks.

• But many companies have shown bare `technical compliance’ with the reporting rules introduced last year and it is "simply not good enough," says Howard Wetston, the Ontario Securities Commission chair.

68

Presenter
Presentation Notes
Despite the hopeful note on the earlier slide, the administrators of Canadian securities exchanges instead of calling for quotas have implemented some disclosure rules. One year after these disclosure rules were put in place their implementation of was thought to be quite lackluster.

However many of these countries have implemented quotas or regulation and both seem quite effective in a country fixed effect model at increasing the share of women on board by 3 to 5%.

More Women in Tops Jobs! Does it Help?

• Female CEOs/Directors have mixed results on firm performance (returns on asset, on equity, profits, Tobin Q, etc.) in firm-fixed effects models– Positive or no effect in Denmark [Smith et al. (2006), Parotta and

Smith (2013)] and in Italy [Amore et al. (2013)]– Negative or no effect in the US [Wolfers (2006), Adams and Ferreira

(2009)], in Norway [Ahern and Dittmar (2012)]• Bertrand, Black, Jensen, and Lleras-Muney (2014) show mixed results on

relative female wages: the Norwegian quotas increased representation of women among top 5 highest earners, but had no effect at other points in the distribution or on the gender pay gap.

Presenter
Presentation Notes
However the impact of these quotas either on firm of performance or on relative female wages had been shown to be quite mixed.

Presentation Notes
Even the simple relationship between female employment share and share of women in senior management home across all quotas and non-quotas countries, pre and post quota years does not show as clear a relationship as for women on corporate boards.

Presentation Notes
Now when we look at yearly transitions from the bottom 90% to the next 9% are using our LWF Data. The dotted line show the transitions for everybody but what is more interesting the focus on a recent cohorts which show that by age 30 men are beginning to make transitions are into the next 9% at much higher rates than women.

Public Policy and Gender Pay Differentials

• Likely the better policies are those that “level the playing field”, but without lowering women’s attachment to the labour marketo Maternity-leave benefits, parental leave provisions But gender neutrality is an issue! (Antecol, Bedard, and Stearns, 2016)o Affordable high-quality child care

• Firm practices are likely also important: o On-site child care and o Flexible hours of work o Paying attention to gender biases at work

74

Presenter
Presentation Notes
So when asked which are the best policies to foster gender equality in the workplace, this leads me to believe that policies and firm practices that help women with the work-life balance will likely home be the more hepful. This is not to say that to women all may be facing on gender bias and other obstacles as the are trying to climb on the organizational ladder wrong but nevertheless on it's a beginning.

Why so Few Women in Top Jobs? Paths for Future Research

Hypotheses from Labour/Behavioral Economics

— Women shy away from competition (Gneezy, Niederle and Rustichini, 2003; Niederle and Vesterlund, 2007)

— Women cannot say “no” to non-promotable tasks (Vesterlund, 2015)— Negotiating divide (Babcock and Laschever, 2003, 2009) — The importance of money vs. people (Fortin, 2008), vs. work flexibility

(Blau and Kahn, 2016; Goldin, 2014)— Differential treatment by customers (i.e. discrimination) (80 cents eBay,

Kricheli-Katz and Regev, 2016)

Presenter
Presentation Notes
Now they are a number of interesting hypotheses to explore in future research: women's lack of competitiveness, the negotiating divide, the importance of money vs. people, the importance of long work flexibility.

Why so Few Women in Top Jobs? Paths for Future Research

Hypotheses from Identity Theory/Social Psychology— Glass cliff phenomenon (Ryan and Haslam, 2007), — Failure of romance of leadership to take hold (Kulich, Ryan,and Haslam,

2007) — Recognition deficit emanating from role incongruity (Eagly and Karau,

2002) — Weak work networks within the firm or the industry (Lalanne and

Seabright, 2011) — Preferences for deontological over utilitarian judgments, weaker team

spirit (Kennedy and Kray, 2013; Friesdorf, Conway, and Gawronski, 2015)
