Investment is the tradeoff between consumption goods used for current satisfaction and capital goods that expand future productive capabilities.- Investment is not just putting money into the stock market. Investment is giving up current satisfaction to obtain greater future production, usually seen as giving up consumption goods to produce capital goods.
- Education and human capital that increase the productive skills and ability of labor.
- Exploration for mineral or fossil fuel deposits that add to land resources.
- Scientific research that expands technology and resource quality.
- The downside of investment is risk. There is no guarantee that you'll get something tomorrow.
Let's consider this basic tradeoff between capital and consumption.- Capital and consumption are the two basic types of goods needed for investment. If we produce more calibrators (capital), then we give up some jogging shoes (consumption).
- This tradeoff IS the fundamental act of investment. In the graph to the right, if we move from bundle A to E to I, we are giving up jogging shoes and getting calibrators.
We are investing!

LONG-RUN AGGREGATE MARKET A macroeconomic model relating the price level and real production under the assumption that ALL prices are flexible. This is one of two aggregate market submodels used to analyze business cycles, gross production, unemployment, inflation, stabilization policies, and related macroeconomic phenomena. The other is the short-run aggregate market. The long-run aggregate market isolates the interaction between aggregate demand and long-run aggregate supply. The key assumption of this model is that ALL prices, especially resource prices, are flexible. The primary result of this model is that the economy achieves long-run equilibrium at full-employment real production.
