Abstract

The best-selling, best known text in Mathematical Economics course, Chiang teaches the basic mathematical methods indispensable for understanding current economic literature. the book's patient explanations are written in an informal, non-intimidating style. To underscore the relevance of mathematics to economics, the author allows the economist's analytical needs to motivate the study of related mathematical techniques; he then illustrates these techniques with appropriate economics models. Graphic illustrations often visually reinforce algebraic results. Many exercise problems serve as drills and help bolster student confidence. These major types of economic analysis are covered: statics, comparative statics, optimization problems, dynamics, and mathematical programming. These mathematical methods are introduced: matrix algebra, differential and integral calculus, differential equations, difference equations, and convex sets.

Abstract

The years following World War II have witnessed an increasing interest in the effects of growth on trade, the patterns of international specialization, and the terms of trade. On the one hand, some English economists have maintained the Ricardian tradition of diminishing returns, rising food prices and, therefore, declining British terms of trade, while,on the other hand Prebisch, Singer, and other critics have attempted to document and explain a long-run decline in the terms of trade of the underdeveloped countries. Finally, in a reaction to this concentration on a single factor as the determinant of international price movements, a group of economists, began a systematic investigation of the role of growth in trade and the terms of trade using neoclassical assumption. This study,particularly in its assumptions regarding demand, falls into the tradition of the last group. However, it extends the tradition by treating growth as a continuous process, dependent on saving out of produced income and the growth rate of population in two trading economies. Therefore, in addition to answering the comparative statics questions regarding the trends in the terms of trade, it develops the conditions which guarantee that the two economies will approach a state of unique long-run balanced growth, in which all per capita variables, as well as the terms of trade, stabilize. Moreover, these methods permit some discussion of changes in the patterns of specialization.

Abstract

There is by now a large literature on the economic aspects of flood control and flood relief policies. The contribution of this paper lies in its careful scrutiny of one single critical aspect of the economics of floods, the choice of land use by a single land­ owner. We analyze that choice using the methods of dynamic programming, and in particular, we show how that choice is dependent on the probability of floods for his piece of land. The theory we have developed here has been developed in the context of floods. In fact, this work grew out of an empirical study of flood plain damages, when we found that the underlying theory was not yet developed.! In fact, we feel that the theory is of much more general interest. It is a theory of optimal investment choice under uncertainty when that uncertainty is a result of destruction or failure of the investment at a random date. This is the case in flood plains, but it is also the appropriate basic theory for understanding investment decisions in the face of earthquakes, fires, war damage, avalanches, and other kinds of disasters. These are only the more dramatic examples of situations where replacement is required at an uncertain date.

Abstract

At this point in time, there is no generally accepted methodology for explaining and predicting human behavior given a product choice situation. This is true despite the critical importance of such meth­ odology to marketing, transportation and urban planning. While the social sciences provide numerous theories to be tested and the mathe­ matical and statistical procedures exist in general to do so, at this point, no single unified theory has emerged. It is generally accepted that to explain product choice behav­ ior,products must be described in terms of attributes. Using anyone of a number of procedures, it is possible to obtain measurements on the attributes of the products under consideration. However, there is no generally accepted methodology. Given the attribute profiles of two products, in order to explain and predict preference, it is necessary to determine the relative importance of each of the product attributes. Once again, there is no generally accepted methodology. There are two basic approaches: The first, called the attitudinal approach, obtains importance measure­ ments directly from respondents using one of many scaling techniques; the second, termed the inferential method endeavors to infer impor­ tances from product preference and attribute data. Since it is gen­ erally felt that respondents are unwilling and/or unable to provide meaningful importance measurements, the inferential method is most widely accepted.
