Question

Will tax cuts that the public perceives to be temporary affect the SRAS and \(L R A S\) curves differently than tax cuts that are perceived to be permanent? Explain your answer.

Short answer

Tax cuts, whether perceived as temporary or permanent, affect SRAS because they can stimulate changes in consumer spending and business investment, leading to increased demand for goods and services. Temporary tax cuts would influence the SRAS more than the LRAS, because the LRAS is driven by structural factors such as potential output of the economy. Permanent tax cuts, however, could affect both SRAS and LRAS by causing both to shift outwards assuming there's no mismanagement leading to inflation.

Step-by-step solution

Definition of SRAS and LRAS

Short Run Aggregate Supply (SRAS) refers to the total quantity of goods and services produced by an economy at a particular price level within a set period of time. Meanwhile, the Long Run Aggregate Supply (LRAS) is the total quantity of all goods produced by an economy at full employment over a period of time.

Impact of Temporary Tax Cuts

A tax cut that is perceived as temporary may stimulate consumer spending in the short term, since consumers would have more disposable income. This can lead to an increase in the demand for goods and services, resulting in an outward shift in the SRAS curve as firms increase production to meet the higher demand. However, since consumers understand the tax cut to be temporary, they may save instead of spend, causing no significant shift in the SRAS. As for the LRAS, temporary tax cuts do not impact it, as it is dependent on structural aspects of the economy such as potential output.

Impact of Permanent Tax Cuts

On the other hand, tax cuts that are perceived to be permanent might have a larger impact on SRAS and LRAS. A permanence in tax cuts ensures a continuous increase in consumer spending and investment, which in turn stimulates increased production, causing the SRAS to shift outwards. A permanent tax cut can also affect the LRAS curve because it could lead to higher investment in capital goods, which could increase an economy’s potential output, causing the LRAS to shift outwards. But, permanent tax cuts could lead to inflation if the government doesn't manage deficit correctly.

Key concepts

Short Run Aggregate Supply (SRAS)

Understanding Short Run Aggregate Supply (SRAS) is critical for grasping the dynamism of an economy over a shorter period. SRAS embodies the quantity of goods and services that producers are willing and able to supply at different price levels within a designated time frame, typically a year or less.

Generally, the SRAS curve can shift due to various factors like changes in input costs or shifts in consumer demand. For instance, a temporary tax cut might lead to an immediate but not sustained increase in household disposable income, potentially resulting in an increase in consumer spending. This can prompt businesses to ramp up production to meet the heightened demand, therefore expanding the SRAS.

However, such a stimulus might not always be effective. If the public perceives a tax cut as fleeting, they may anticipate future tax hikes and choose to save instead, curtailing any possible shift in the SRAS. Therefore, the perception of the tax cut's lifespan plays a crucial role in influencing SRAS.

Long Run Aggregate Supply (LRAS)

While SRAS focuses on short-term economic fluctuations, Long Run Aggregate Supply (LRAS) represents the fundamental, structural capabilities of an economy. LRAS is depicted as the total output of goods and services that an economy can produce when it fully employs all available resources, without worrying about price level fluctuations.

The positioning of the LRAS curve is especially stable as it is shaped by factors like technology, capital, labor forces, and institutional reforms. Unlike SRAS, LRAS isn't easily swayed by temporary conditions like short-lived tax changes. Rather, alterations in LRAS occur due to changes in long-term productive capacity, perhaps influenced by permanent tax cuts that encourage increased investment in capital and boost economic productivity, thereby potentially shifting LRAS outward.

Temporary vs Permanent Tax Cuts

The contrast between temporary and permanent tax cuts provides insight into behavioral economics and the disparate impacts these measures can have on aggregate supply. A temporary tax cut might spark an immediate surge in disposable income, however, its fleeting nature may not significantly shift consumer spending habits or businesses' investment strategies.

Psychology of Tax Cuts

Consumers and businesses are more likely to alter their long-term financial planning based on the permanence of tax reliefs. Permanent tax cuts, on the other hand, can shape expectations differently, fostering a milieu where long-term investments become more appealing.

Thus, while temporary tax cuts might affect SRAS by offering a temporary boost, it's the permanent tax cuts that are necessary to reshape the economy and influence the LRAS curve by promoting sustainable growth and investments.

Consumer Spending and Investment

Consumer spending and business investment are two primary engines that drive an economy's growth. They are also key determinants of shifts in both SRAS and LRAS.

When consumers spend more, businesses experience increased demand for their products and services, which bolsters production and shifts SRAS to the right. Investment by businesses in capital goods like machinery and technology enhances efficiency and productive capacity, leading to a shift in LRAS as the economy grows.

Impact of Tax Policies

Tax policies can critically influence these engines. Temporary tax cuts typically result in short-lived spikes in consumer spending, lacking the ability to encourage significant business investment. In parallel, permanent tax cuts are more likely to result in sustained increases in both consumer spending and business investment, contributing to long-term economic growth and shifts in both the SRAS and LRAS curves.
