A recession is defined as the economy shrinking for two consecutive quarters, indicated by a decrease in GDP, which results from factors like overproduction and low consumer confidence. Economic indicators such as unemployment rates, personal income, and consumption rates help assess the health of an economy, with government interventions through fiscal and monetary policies proposed to mitigate recession impacts. Understanding the dynamics of supply and demand is crucial, as a decline in consumer confidence can trigger a downward spiral leading to reduced spending and increased saving.
