EFFICIENT SEARCH, DETERMINANTS: Two factors that affect information search are (1) the amount of purchase and (2) frequency of purchase. Goods that are relatively expensive increase the potential benefit of search. For example, saving 10 percent on the purchase price of a house is significantly more than saving 10 percent on the price of bar of soap. Buyers are thus likely to undertake extensive search when buying a house, but not for soap. Goods that are purchased more frequently also don't require extensive search activities. Since buyers already know the "best places" to buy the "highest quality" products at the "lowest prices" for frequently purchased goods, little can be gained from search.

SAVING-INVESTMENT MODEL A variation of the Keynesian injections-leakages model that includes the two private sectors, the household sector and the business sector. This variation, more formally termed the two-sector injections-leakages model, captures the interaction between induced saving (and indirectly induced consumption expenditures) and autonomous investment expenditures. This model provides an alternative to the two-sector aggregate expenditures (Keynesian cross) analysis of the macroeconomy, including equilibrium, disequilibrium, and the multiplier. Equilibrium is identified as the intersection between the saving line and the investment line. Two related variations are the three-sector injections-leakages model and the four-sector injections-leakages model.
