In the theory of welfare economics, external economies are defined as those unpaid benefits which go to third parties. A set of premises can be incomplete in two senses: first, in not listing all relevant causes (thus violating the whole truth); second, in not explicitly listing all the implicitly required idealizations (thus hiding its violation of nothing but truths). It’s about access (like politics or philosophy) - and there never will be the only one true and correct economic theory. National governments also have an interest in theories of economics.

We consume health services as either an investment in our future health, to cope with chronic illness, or recover from acute illnesses or accidents. In Chapter 2 we focused on experiments in which the subjects have to choose between pairs of simple bets, where each bet is usually composed of only two outcomes. In this field, causal-realist price theory provides a bridge between the theory of the firm and the study of comparative economic systems. Rostow's theory can be classified as "top-down," or one that emphasizes a trickle-down modernization effect from urban industry and western influence to develop a country as a whole. In these premises, agents were described as selfish and seeking nothing but maximum wealth, and returns in agriculture were described as diminishing.

John Maynard Keynes' economic theories are still used today by the Federal Reserve to manage monetary policy. But this is not the issue we discuss in this chapter, because we are focusing on possible deviations from the classical models due to irrational choices or inefficient selection of choices by the investors, and not on the effects of market frictions. Suppose that indeed the preceding assumptions are intact. Education, poverty and health are some of the social issues that often affect economics and, in social theories of economic development, these are the key issues. Keynesian believes that the employment and production level is decided by the aggregate demand level. By 1935 he outlined his theory of employment, demolished the then-orthodox remedy for a depression-that is, wage cutting-and pinpointed the importance of investment for economic dynamics. 1  Keynesians believe consumer demand is the primary driving force in an economy. Because price and income are covered well in separate articles, focus will be on the primary demographic, social, and above all, health characteristics that determine health care demand from the consumer point of view. Statistical principles also play a role. Unlike the previous cases, the answer here is negative.
