Q.Discuss briefly, how the government can control the situation of deflation using the following :

Controlling Deflation through Fiscal Policy

Deflation — a sustained fall in the general price level — signals deficient aggregate demand. The government can counter it by adopting an expansionary fiscal policy that raises aggregate demand and pushes the economy back toward full employment.

(a) Taxation Policy

During deflation, the government should reduce taxes (both direct taxes like income tax and indirect taxes like GST). Lower taxes increase disposable income in the hands of households, which raises consumption demand ($C$). Similarly, reduced corporate taxes boost retained earnings and encourage private investment ($I$). Both channels lift aggregate demand ($AD = C + I + G + (X - M)$), helping reverse the deflationary spiral.

(b) Government Expenditure Policy …

Deflation is a persistent fall in the general price level, typically caused by insufficient aggregate demand in the economy. When consumers and firms postpone spending in anticipation of even lower prices tomorrow, demand contracts further, output falls, unemployment rises, and the economy spirals downward. The government's fiscal toolkit offers two powerful levers to reverse this: taxation policy and expenditure policy. Both work by raising aggregate demand, but through different channels.

(a) Taxation Policy

The government can reduce taxes to combat deflation. When personal income tax rates are cut, households retain more disposable income — the income available after taxes. Higher disposable income translates directly into higher consumption demand, because people spend a fraction (the marginal propensity to consume, $MPC$) of every additional rupee they receive.

Similarly, cutting corporate taxes leaves firms with higher post-tax profits. This encourages investment spending on new machinery, factories, and technology, especially when businesses see rising consumer demand on the horizon. Lower indirect taxes (like GST) reduce the final price of goods, making consumption more attractive and breaking the deflationary expectation that "prices will fall further."

The impact is amplified through the multiplier effect. An initial tax cut raises disposable income by, say, ₹100 crore. Households spend $MPC \times 100$ crore, which becomes income for others, who in turn spend $MPC^2 \times 100$ crore, and so on. The total increase in national income is:

(The negative sign reflects that a reduction in taxes $\Delta T < 0$ raises income.) The tax multiplier is smaller in absolute value than the expenditure multiplier because the first round of a tax cut is partly saved, not entirely spent.

(b) Government Expenditure Policy

The government can increase public spending — on infrastructure (roads, ports, schools), social programs (MGNREGA, health schemes), or direct purchases of goods and services. This injects demand into the economy immediately and directly, without waiting for households to respond.

Every rupee of government expenditure becomes income for construction workers, suppliers, contractors, and so on. They spend a portion (again, $MPC$) of that income, creating a second round of demand, which generates a third round, and the process continues. The expenditure multiplier is:

So an increase in government spending $\Delta G$ raises equilibrium national income by $\Delta Y = k \times \Delta G$. If $MPC = 0.8$, the multiplier is $5$, meaning ₹100 crore of public spending ultimately raises income by ₹500 crore. …
