Revaluation

Originally, HKMA fixed the rate at US$1:HK$7.8

If HKMA set the rate at US$1:HK$6

(meaning that less HK dollar can be bought by US$1)

(value of HK dollar increases)

the rate of HKD against USD rises

The government re-pegs exchange rate at a higher level

Devaluation

Originally, HKMA fixed the rate at US$1:HK$7.8

If HKMA set the rate at US$1:HK$9

(meaning that more HK dollar can be bought by US$1)

(value of HK dollar decreases)

the rate of HKD against USD falls

Balance of payment (BOP) account

Definition The record of an economy’s receipts and payments arising from

external transactions

BOP account of HK For a specific time period Economic transactions between HK residents and non-residents

Balance of payment (BOP) account

Components of the BOP account: Current account (經常帳 ) Capital and finance account (資本及金融帳 )

International purchases or sales of

assetsCapital transfers

All external transactions not

included in capital & financial account

Balance of payment (BOP) account

Current account:1. Goods (visible trade) Net receipt brought by merchandise trade (商品貿易 ) Receipt: Exports of goods, e.g. garments, jewellery… Payment: Imports of goods, e.g. rice, cars…

Types of BOT:

Balance of visible trade = Total exports of goods – Total imports of goods

Trade deficit (貿易赤字 ) Exports < Imports BOT < 0

Balance BOT (貿易平衡 ) Exports = Imports BOT = 0

Trade surplus (貿易盈餘 ) Exports > Imports BOT > 0

Current account:

2. Services (invisible trade)

Net receipt brought by services

Receipt: Exports of services, e.g. local airline…

Payment: Imports of services, e.g. World Cup broadcasting…

Balance of invisible trade = Total exports of services – Total imports of services

Balance of payment (BOP) account

Current account:3. Factor income Net income from abraod All forms of investment income

Dividends Interest from deposit

4. Current transfers Unilateral (單向 ) transfer of goods and capital No economic value being received in return For example: donations, remittances 匯款

Net income from abroad = Factor income from abroad – Factor income paid abroad

Balance of payment (BOP) account

Current account balance:Total balance of the 4 components: Visible trade Invisible trade Factor income Current transfer

Current account balance

= Balance of (Goods + Services + Factor income + Current

transfer)

Balance of payment (BOP) account

Given the following table, calculate the current account balance of HK:

Current account balance= ( $500 - $200 + $350 - $100 + $50 - $80 - $120 ) million= $400 million

Imports of goods 200

Exports of services 350

Imports of services 100

Dividends from USA company 50

Taxation Adam Smith’s principles of taxation

Equity Taxation should be fair. Taxes are directly proportion to people’s income,

i.e. those who earn more income need to pay higher tax

Certainty Clearly define the responsibilities to taxpayers Clear tax calculation method Clear tax payment deadline Clear modes of payment

(in person / online / PPS / credit card…)

Taxation Adam Smith’s principles of taxation

Convenience Deadline & payment method: convenient to taxpayers Allow enough time for payment E.g. Salary tax in Hong Kong:

May: Submission of Tax Return – Individual October: Notification of tax payment January: First installment April: Secondary installment

Economy Cost of tax collection should be kept minimum. Online / PPS tax payment Cost of tax collection

Tax base (稅基 ) The tax base of an economic territory means

activities (e.g. buying car, taking flight overseas) revenue (e.g. salaries, profits) assets (e.g. properties, cars)

on which taxes are charged.

The government’s scope of taxation.

Broader the tax base more people need to pay tax more source of taxation more stable tax revenue

Classification of tax

By tax burden Direct tax Indirect tax

By tax rate Progressive tax Proportional tax Regressive tax

Classification by tax burden

Direct tax The tax burden cannot be shifted to others by taxpayers. Examples:

Salaries tax Charges directly on the salary

Profits tax Charges directly on profit-making firms

Property tax Charges directly on rental income earned from land or properties.

Classification by tax burden

Indirect tax The tax burden can be shifted to others by taxpayers Examples:

Duties (應課稅品 ) Liquors (酒類 ) Tobacco (煙草 ) Hydrocarbon (燃油 ) Methyl alcohol (甲醇 )

Rates (差餉 ) Betting duty (博彩稅 ) Stamp duty (印花稅 ) First registration tax (汽車首次登記稅 )

Classification by tax burden

Indirect tax How is the tax burden shifted? Examples:

Duties: Tobacco Gov’t charges tax on tobacco traders

Tobacco traders raise the price of cigarettes Consumers need to pay more for the cigarettes

i.e. The tax burden is shifted to consumers through increase in price

all kinds of sales taxes are indirect tax

Tax base: Direct tax vs. Indirect tax

Direct tax Levied on companies and salaried workers Only tax on profit or income earning Number of taxpayers is limited Even worse if no profit or salary Tax base is narrow

Indirect tax Imposed on taxable goods and services Tax on anyone who made consumption Number of taxpayers is large Tax base is broader

Tax base (稅基 )

Which of the following can broaden (擴闊 ) the tax base of Hong Kong?

(1) Greatly decrease the basic tax allowance of the salaries tax.

(2) Impose a general sales tax.(3) Increase the current indirect tax rate.

A. (2) onlyB. (1) and (2) onlyC. (2) and (3) onlyD. (1), (2) and (3)

Answer: B

Stable tax revenue: Direct tax vs. Indirect tax

Gov’t revenue fluctuates with economic cycles (經濟週期 ) Direct tax

During economic recession (經濟衰退 ) Companies: Low profit Workers: Low salaries Therefore, gov’t has less profit and salaries taxes

During the time of economic boom (經濟繁榮 ) Greatly increase in tax revenue

Tax revenue is not stable

Indirect tax No matter what the time is, people need to consume Tax revenue is relatively more stable

Tax rate and tax revenue:Why is there smuggling (走私 )?

Suppose the gov’t wants to raise tax revenue Way to achieve: tax rate (e.g. duty on tobacco) Traders shift the tax burden to consumer People needs to pay more To avoid higher price, consumers buy smuggled cigarettes incentive of smuggling market Finally, lower tax revenue gained

Conclusion Higher tax rate

illegal activities: smuggling and tax evasion (逃稅 ) tax revenue cost to fight crime

Tax rate and tax revenue Laffer Curve (textbook p.189)

Two extremes (e.g. salaries tax): 0% tax rate No tax revenue 100% tax rate All income paid for tax (i.e. no personal income)

No one will work No tax revenue

Optimum level (t*) If current tax rate < t*,

tax rate tax revenue If current tax rate > t*, tax rate tax revenue

The effects of tax on income redistribution

1. Narrow the gap between the rich and the poor The government’s revenue and expenditure

Tax revenue from the taxpayers who earn taxable salaries the companies which gain profit

Expenditure provide inexpensive or free services for the poor or low income earners subsidies for the unemployed or low income groups

Progress income tax Higher income earners pay higher a tax rate. Lower income earners pay lower a tax rate.

The effects of tax on income redistribution

2. Salaries tax be adjusted A more equal income distribution

A. Increase the basic tax allowance

Personal allowance

Dependent children

Dependent parents/grandparents maintained by you

More low income earners can be excluded from paying tax

The effects of tax on income redistribution

2. Salaries tax be adjusted A more equal income distribution

b. Decrease the tax rates of all tax bands

That is, tax rate of the first three bands of $40,000 taxable

income

Lower tax burden of the middle class

More low and middle classes pay less tax burden.

The effects of tax on income redistribution

2. Salaries tax be adjusted A more equal income distribution

c. Increase the standard tax rate

Very higher income earners pay a standard tax rate

Increase in standard tax rate will affect high income groups only

More tax revenue can be collected from the high income groups

The effects of tax on income redistribution

3. Goods and Services Tax (GST)

Suppose 20% GST is charged on buying a book ($100).

Therefore, $20 is the tax payment.

To a low income (income = $200) buyer,

tax rate = = 10%

To a high income (income = $40,000) buyer

tax rate = = 0.05%

GST is a regressive tax, more uneven income distribution.

Argument of imposing GST in HK

For Broaden the tax base Many examples from foreign countries, e.g. Japan, U.S.A. Reasonable to “buy more goods, pay more tax” Fair tax system. All people need to pay GST.

Against Increase tax burden Worry of increase in tax rate High cost of tax calculation High cost of tax collection P Qd , lower consumption lower GDP Destroy the simple tax system of HK Income disparity
