The production possibilities frontier (PPF) for guns versus butter. Points like X that are outside the PPF are impossible to achieve. Points such as B, C, and D illustrate the trade-off between guns and butter: at these levels of production, producing more of one requires producing less of the other.
Keynesian economics advocates the use of automatic and discretionary countercyclical policies to lessen the impact of the business cycle. One example of an automatically countercyclical fiscal policy is progressive taxation. By taxing a larger proportion of income when the economy expands, a progressive tax tends to decrease demand when the ...
Real business-cycle theory (RBC theory) is a class of new classical macroeconomics models in which business-cycle fluctuations are accounted for by real, in contrast to nominal, shocks. [1] RBC theory sees business cycle fluctuations as the efficient response to exogenous changes in the real economic environment.
With FIFO, the cost of inventory reported on the balance sheet represents the cost of the inventory purchased earliest. FIFO most closely mimics the flow of inventory, as businesses are far more likely to sell the oldest inventory first. Consider this example: Foo Co. had the following inventory at hand, in order of acquisition in November:
A macroeconomic model is an analytical tool designed to describe the operation of the problems of economy of a country or a region. These models are usually designed to examine the comparative statics and dynamics of aggregate quantities such as the total amount of goods and services produced, total income earned, the level of employment of productive resources, and the level of prices.
Economic graphs are presented only in the first quadrant of the Cartesian plane when the variables conceptually can only take on non-negative values (such as the quantity of a product that is produced). Even though the axes refer to numerical variables, specific values are often not introduced if a conceptual point is being made that would ...
Lucas's model dominated new classical economic business cycle theory until 1982 when real business cycle theory, starting with Finn E. Kydland and Edward C. Prescott, [8] replaced Lucas's theory of a money driven business cycle with a strictly supply based model that used technology and other real shocks to explain fluctuations in output. [9]
New classical economics contributed the methodology behind real business cycle theory [6] and new Keynesian economics contributed nominal rigidities (slow moving and periodic, rather than continuous, price changes also called sticky prices). [7] The new synthesis provides the theoretical foundation for much of contemporary mainstream economics.
