To address a recessionary gap in Zeta's economy, the first step is to identify the current unemployment rate. This helps to understand how many people are out of work and gives a clear picture of the economic situation. Next, we assess the potential output using the production possibilities curve, which shows how much the economy can produce if all resources are used efficiently. After understanding these factors, we can implement fiscal policies to stimulate demand, such as increasing government spending or cutting taxes to encourage spending. Finally, it is important to monitor the effectiveness of these policies over time to see if they are helping to reduce unemployment and boost the economy.
