As we have seen, criticism of this type is largely beside the point unless supplemented by evidence that a hypothesis differing in one or another of these respects from the theory being criticized yields better predictions for as wide a range of phenomena.
He argued for, among other things, a volunteer army, freely floating exchange rates, abolition of licensing of doctors, a negative income tax, and education vouchers. The two schools of thought had both different beliefs about how the economy works and different ideological predilections.
Essays in positive economics 1953 Already, economists are aware that prices have been rising relatively rapidly in major service sectors, such as education and health care, while prices have been rising slowly or even falling in major goods industries, such as home electronics and computers.
We know that market prices are important for coordinating specialization and division of labor in a complex economy. In the first place, the particular facts that enter at each stage are partly an accident of the collection of data and the knowledge of the particular investigator.
Those curmudgeons who argued that economics is not a "closed system" were correct.
But economic theory must be more than a structure of tautologies if it is to be able to predict and not merely describe the consequences of action; if it is to be something different from disguised mathematics. In the particular case of falling bodies a more general, though still incomplete, theory is available, largely as a result of attempts to explain the errors of the simple theory, from which the influence of some of the possible disturbing factors can be calculated and of which the simple theory is a special case.
The importance of its subject matter to everyday life and to major issues of public policy impedes objectivity and promotes confusion between scientific analysis and normative judgment.
But it is also consistent with competitive conditions and a positively or negatively sloping supply curve with the required compensating shift in the demand curve or the supply curve; with monopolistic conditions, constant marginal costs, and stable demand curve, of the particular shape required to produce this result; and so on indefinitely.
This evidence is in part similar to that adduced on behalf of the billiard-player hypothesis - unless the behavior of businessmen in some way or other approximated behavior consistent with the maximization of returns, it seems unlikely that they would remain in business for long.
There is really no avoiding some movement in the direction of understanding economics as an interpretive discipline, a little like history. In my own view, for instance, there is no simple monetary or fiscal solution to unemployment.
Viewed as a language, theory has no substantive content; it of tautologies. In examining subjects like these, economists could greatly reduce their usage of mathematical expression without losing anything in terms of effective theory.
To be important, therefore, a hypothesis must be descriptively false in its assumptions; it The converse of the proposition does not of course hold: Under such circumstances perfect competitors would have reduced the quantity offered for sale at the previously existing price. As Daniel Bell put it in his contributionToday, there is general agreement that government economic management and policy is in disarray.
Regarding the question of testing procedures, the economics profession was roiled in that period by the "Lucas critique" as applied to macroeconometric models. Do we know where to file each individual item, or is there considerable ambiguity. Economists have always had their biases about which sorts of theories seemed reasonable; some of these biases are idiosyncratic, as when one economist is inclined to believe that labor demand responds very little to a change in wage rates and another is inclined to believe that labor demand responds a great deal.
Instead, economics deals in speculative interpretations and must continue to do so. By this time, macroeconomics was the most troubled sub-discipline of economics. Other monetarists, notably Scott Sumner and Robert Hetzel, blame tight money during the crisis. Over the past 50 years, in particular, they have largely attained that status.
There are two problems embedded in these mathiness critiques. Mathematical models are considered more rigorous than verbal arguments, but the process of modeling serves to narrow the scope of economic thinking. If the system does change, of course the prediction will be falsified, and this is what happens in social systems all the time Of course, neither the evidence of the economist nor that of the sociologist is conclusive.
The introduction of two substeps in selecting a hypothesis makes this problem arise at the two corresponding stages and gives it a special cast. The five Clark medalists from published a total of four papers in Econometrica and none in the Journal of Economic Theory.
With mathematical modeling, the question concerns the tradeoff between rigor and relevance. Any researcher who tries to replicate a finding using appropriate methods should be able to confirm it. It seems not at all unreasonable that excellent predictions would be yielded by the hypothesis that the billiard player made his shots as if he knew the complicated mathematical formulas that would give the optimum directions of travel, could estimate accurately by eye the angles, etc.
War against the http: It for econ introduction to economics, the hunger games. This is clearly a far less economical presentation of the hypothesis than the statement that leaves seek to maximize the sunlight each receives. They make interpretations that suit their political biases, but otherwise their interpretations are not justified.
Yet it seems obvious that, while general considerations can be formulated to guide such judgments, they can never be comprehensive and cover every possible instance; they cannot have the self-contained coherent character of Euclidean geometry itself.
