Best if printed in landscape. Production Theory -- Introduction
Management has been described as decision making. Among the many decisions that managers make are questions about producing a good or service, such as "what product should I produce," "how should I produce this product," and "how much should I produce." This series of web pages focuses on economic concepts that pertain to the third question -- how much should I produce. The discussion assumes that manager has a good sense of what to produce and how it will be produced; that is, the other two questions. The purpose of this series of web pages is to present a general overview of several economic concepts relating to the broad topic of production theory. The topics include
Embedded in these topics are secondary discussions about 1) short-run versus long-run, 2) fixed inputs and variable inputs, and 3) fixed costs and variable costs. Introduction Several assumptions form the foundation for this discussion. The first assumption is that the manager wants to produce the quantity of output that will maximize profit. A second assumption is that the business can increase production or output by using more input, and that increased output means increased profit.
This web page introduces why the answer to the simple question "how much should I produce" is complex. The page also introduces how a manager can decide how much input to use to maximize profit.
A third assumption is that there is more than one way or one "receipe" for producing a product. Take the example of a chocolate cake but think about it from a slightly different perspective. Instead of asking "how much input should I use to maximize profit," a baker may ask " how much chocolate should I use in making the cake?" That is, the baker could bake several cakes using the same amount of flour, sugar and milk and the same number of eggs, but vary the amount of chocolate in each cake. The cake made with a small quantity of chocolate may not have much flavor and thus not achieve the goal of baking a good chocolate cake. At the other extreme if the baker used a large quantity of chocolate in one cake, the flavor may be bitter. Neither of these decisions achieve the goal of baking a good chocolate cake. Some quantity of chocolate in between these two extremes will likely result in an acceptable cake. A similar situation can arise for a wheat farmer who uses a small quantity of fertilizer per acre; the farmer may not reach the yield potential for the acre of land. However, using a large quantity of fertilizer may also lead to diminished production; that is, too much fertilizer can stunt the growth of the crop. Somewhere between these two extremes is the quantity of fertilizer that achieves the farmer's goal of maximizing profit from raising wheat on the acre of land. There is more than one way to produce a product and the "receipe" that one business uses will be different than the receipe used by another business. Each manager must determine the receipe the works best for his or her business. What one manager does may not make sense for another manager. Each manager needs the skills to decide which "receipe" is most appropriate for his or her business. In summary, the purpose of these materials is to introduce principles, including economic principles that help describe a decision making process for the baker, the farmer and many other decision makers. Restated, this series of web pages demonstrates that these economic concepts are relevant in making many production decisions.
The next section introduces the concept of diminishing marginal productivity -- a natural phenomenon that impacts decision making.
