Investment Volatility as a Driver of Business Cycles

Explaining the Relative Smoothness of Consumption and Volatility of Investment

An economist is analyzing data for a country that has just gone through a recession. They observe that during the deepest part of the recession, household spending on goods and services decreased by 3%, while firms' spending on new factories and equipment decreased by 20%. Which economic principle do these observations best illustrate?

Spending Patterns During an Economic Downturn

In a typical economy experiencing a business cycle, the absolute percentage change in spending on new housing and machinery is generally smaller than the absolute percentage change in spending on food and services.

An economy experiences a sudden, one-time increase of $50 billion in autonomous investment spending on new factories. Assuming no other changes, what is the most likely ultimate effect on the economy's total output as described by the multiplier model?

Comparing Economic Responses to a Spending Shock

A wave of pessimism about the future of the economy causes firms to significantly reduce their spending on new machinery and buildings. According to the logic of the multiplier model, arrange the following events in the chronological sequence that would follow this initial shock.

Analysis of the Economic Amplification Effect

Explaining the Amplification of Spending

According to the multiplier model, if a government reduces its spending by $100 million to balance its budget, the total output of the economy will also decrease by exactly $100 million, as the reduction in demand is directly offset by the decrease in government expenditure.

Match each stage of the economic process described below with its correct description, illustrating how an initial change in spending is amplified.

In a simplified economy, a firm spends an initial $1,000 on new machinery. This $1,000 becomes income for the machinery's producers. If these producers, in turn, spend 80% of this new income on other goods and services, this second round of spending will add an additional $____ to the economy's total demand.

Evaluating Economic Stimulus Policies

An economy experiences a $10 billion increase in autonomous investment. In which of the following scenarios would this initial change in spending lead to the largest total increase in national output?
