Explain how an increase in the rate of income tax might affect actual and potential economic growth.
Income tax is a direct tax, levied on individuals' income (personal income tax) or on firms' profits (corporate income tax). Changes in income tax rates can affect both actual economic growth, the increase in real national income over time, and potential economic growth, the increase in productive capacity determined by long run aggregate supply.
Effects of higher personal income tax. An increase in personal income tax reduces after tax disposable income. With less purchasing power, households reduce consumption, and since consumption is a major component of aggregate demand, AD falls, shifting leftward from AD0 to AD1. Real national income falls from Y0 to Y1, slowing actual economic growth, and the initial fall in consumption is magnified through the multiplier effect as lower spending reduces firms' revenues and incomes further. Higher personal income tax may also harm potential growth: higher rates reduce the financial incentive to work, especially for higher income earners, which can lower labour supply and effort. This may shift long run aggregate supply leftward, reducing full employment output from YF0 to YF1.
Effects of higher corporate income tax. An increase in corporate income tax reduces firms' after tax profits, which may discourage investment. Investment is a component of aggregate demand, so AD falls from AD0 to AD1, reducing real national income from Y0 to Y1 and slowing actual growth, again potentially by a multiplied extent. A sustained fall in investment also reduces potential growth: fewer additions to the capital stock such as machinery, infrastructure and technology limit productivity improvements, shifting long run aggregate supply leftward and lowering full employment output from YF0 to YF1.
In summary, higher income tax can reduce actual growth by lowering aggregate demand through reduced consumption and investment, and may hinder potential growth by weakening labour incentives and capital accumulation. The overall impact depends on the size of the tax rise and the responsiveness of households and firms, but higher income taxes generally pose downward risks to both short run and long run growth.
Separate personal and corporate income tax, trace each through AD (consumption or investment) for actual growth and through LRAS (incentives or capital) for potential growth.
Discuss whether giving more generous transfer payments is the most appropriate policy measure to achieve inclusive growth in Singapore.
- Define inclusive growth and its measurement, and frame transfer payments as one candidate policy.
- Develop how transfer payments can reduce inequality and support growth, distinguishing targeted from universal schemes.
- Set out the limitations of transfers, including the symptom versus root cause point and fiscal sustainability.
- Introduce an alternative supply side approach and the channel through which it raises incomes sustainably.
- Weigh the immediate reach of transfers against the durability of the alternative.
- Conclude on the most appropriate measure, framed as a complementary policy mix.
