List four factors that could shift the consumption schedule?

Four factors that could shift the consumption schedule include changes in consumer income, alterations in consumer expectations about future economic conditions, variations in the price level, and changes in taxes or transfer payments. An increase in income typically leads to higher consumption, while negative economic expectations may cause consumers to save more. Fluctuations in the price level can affect purchasing power, and changes in taxes can directly influence disposable income, thereby impacting consumption patterns.
