PARETO IMPROVEMENT: Based on the Pareto efficiency criterion, the notion that an action improves efficiency if it is possible for one person to benefit without anyone else being harmed. A Pareto improvement is possible if the economy has idle resources or market failures. With idle resources, more production is possible to help some without hurting others. With market failures, corrective actions can eliminate deadweight loss that can then be use for benefits economy-wide. A contrasting condition for attaining efficiency is the Kaldor-Hicks improvement.

    Aggregate Demand

    This lesson introduces aggregate demand, the demand-side of the aggregate market. The aggregate market is the key model used to explain and analyze the workings of the macroeconomy and aggregate demand is a critical half of this model (the other is aggregate supply). Taking a clue from market demand, this lesson examines the nature of aggregate demand, including the relation between the price level and aggregate expenditures, the reason the aggregate demand curve is negatively sloped, and the assorted aggregate demand determinants that cause the aggregate demand curve to shift.

    • The first unit of this lesson introduces the concept of aggregate demand and how it fits into the study of macroeconomics in terms of the aggregate market and circular flow.
    • In the second unit, we example the four aggregate expenditures -- consumption, investment, government purchases, and net exports -- the make up aggregate demand.
    • The third unit then examines the aggregate demand curve that captures the aggregate demand relation between the price level and aggregate expenditures, especially the importance of the real-balance, interest-rate, and net-export effects.
    • A look at the assorted aggregate demand determinants that shift the aggregate demand curves is the topic of the fourth lesson.
    • We end this lesson in the fifth unit with a look how demand-management policies work to stabilize business cycles through aggregate demand.

    An economic model relating the price level and real production that is used to analyze business cycles, gross production, unemployment, inflation, stabilization policies, and related macroeconomic phenomena. The aggregate market, inspired by the standard market model, but adapted to the macroeconomy, captures the interaction between aggregate demand (the buyers) and short-run and long-run aggregate supply (the sellers). Also known by the names AS-AD model or income-price model, the aggregate market is THE cornerstone model of macroeconomic analysis.
