THREE-SECTOR AGGREGATE EXPENDITURES LINE: A graphical depiction of the relation between aggregate expenditures by the three domestic macroeconomic sectors (household, business, and government) and the level of aggregate income or production. The three-sector aggregate expenditures line combines consumption expenditures, investment expenditures, and government purchases. The slope of this aggregate expenditures line is based on the marginal propensity to consume, adjusted for marginal propensities of the other expenditures that are assumed to be induced when constructing the line. This is one of three aggregate expenditures lines based on the number of sectors included. The others are the two-sector aggregate expenditures line and the four-sector aggregate expenditures line.

                           MARGINAL COST OF SEARCH: The incremental cost incurred by additional search effort is the marginal cost of search. Marginal cost of search, also termed marginal search cost, is comparable to marginal cost of short-run production analysis. Marginal cost of search increases with an increase in search effort and is represented by the marginal cost of search curve. This is one half of the efficient information search decision. The other is marginal benefit of search. Marginal cost of search is the additional cost generated through extra effort directed toward the production of, or search for, information. The cost of information search includes the opportunity cost of using the four factors of production -- labor, capital, land, and entrepreneurship. The extra cost generated by search effort increases with the amount of search.The marginal cost of search is combined with the marginal benefit of search to identify the efficient amount of information search. Acquiring information is beneficial, but doing so incurs a cost. Information is produced. Information is consumed. Efficiency is achieved by equating the incremental opportunity cost incurred in the production or acquisition of information (marginal cost of search) with the increment benefit generated from the information (marginal benefit of search).

| One half of the efficient search decision is based on the cost incurred in the search. This is embodied in the marginal cost of search. Information search incurs the same types of cost as the production of most goods:- Labor: An important component of search cost is human search effort. The time a person spends making phone calls, reading through a newspaper, and driving around town is an important search cost. And of course, comparable to other goods, the production of information goods such as newspapers, television programs, and advertising all require labor effort.
- Capital: The cost of using assorted capital -- buildings, vehicles, tools, and equipment -- is incurred for search effort as it is for the production of other goods. A car is used to drive from store to store. A telephone is used to call about prices. Printing presses are used to produce newspapers and magazines. Computers are used to access information over the Internet.
- Land: The cost of land, especially the cost of raw materials, is the third search effort cost. The cost of gasoline to fuel vehicles, of the paper used in printed materials, of the coal used to generate electricity used to operated computers, are all information search cost components.
- Entrepreneurship: Lastly, the normal profit incurred in the use of entrepreneurial services is as important for information search and production is for any other goods.
Marginal cost of search increases with an increase in search effort, comparable to increasing marginal cost for any type of production. Additional search effort requires additional scarce resources with alternative uses and increasing opportunity cost. For example, the first hour of searching for the lowest price of Wacky Willy Stuffed Amigos might entail an inexpensive walk to a nearby drug store. The next hour might then require a more distant and expensive drive to a discount super center. Further searching requires additional increasingly cost resources.Marginal Cost of Search CurveThe marginal cost of search is represented by the positively-sloped marginal cost curve.
