Final answer:
Consumption, investment, government spending, exports, and imports are all components of aggregate demand in a market-orientated economy. Keynesian analysis suggests that these components greatly influence economic activity, and adjustments in these areas can cause shifts in overall economic performance.
Step-by-step explanation:
Consumption, investment, government spending, exports, and imports are all critical components of aggregate demand within an economy. In the context of a market-orientated economy, these elements are neither entirely complementary nor opposing but interact in complex ways to determine the overall level of economic activity. Consumption changes due to various factors such as income, taxes, and wealth. Investment varies with expected profitability and interest rates, while government spending is influenced by political decisions. Exports and imports fluctuate based on relative economic performance and prices between countries.
According to Keynesian analysis, aggregate demand is often the primary cause of economic events like recessions. Keynesian economists argue that in the short run, prices and wages can be sticky, impeding the economy's ability to quickly adjust to shocks. This stickiness can lead to unemployment when there is a decrease in demand. Furthermore, the Keynesian perspective introduces the concept of the expenditure multiplier, highlighting how changes in spending can lead to more than proportionate changes in economic output.
