The purpose of this article is to offer an overview of contract theory, a highly successful and active research area in microeconomics, with particular emphasis on its history and influence on modern economics. According to Bolton and Dewatripont (2005), currently a standard textbook in this field, the theory of incentives, information, and economic institutions is generally referred to in short as contract theory. Contract theory is thus a theory of imperfect markets, mainly because of asymmetric information such as moral hazard and adverse selection. Contract theory is also a theory of economic institutions and as such applies far beyond markets. The basic model of moral hazard and that of adverse selection both use agency (or principal-agent) relationships as the main analytical framework, in response to various attempts to lay open the black-box nature of the firm in the standard neoclassical model. Furthermore, theories of boundaries of the firm, originating out of Coase's classical work, are today analyzed in the framework of incomplete contracts that leads to the third basic model of contract theory, along with those of moral hazard and adverse selection. Although these basic models are games with specific extensive forms, they are formulated as optimization problems subject to incentive compatibility and participation conditions, and are solved without explicit reference to equilibrium concepts. Contract theory is thus related to both price theory and game theory, but it has developed its own analytical frameworks and tools to solve problems under conditions of asymmetric information or incomplete contracts. Contract theory is also a theory of incentive design. Incentive design is not important under perfect competition but is crucial when there is asymmetric information or contractual incompleteness. Myerson claims that today, "economists can define their field more broadly, as being about the analysis of incentives in all social institutions." (Myerson 1999) I argue that it is contract theory that enables us to define today's field more broadly.

Over the past decade, a number of economists at the Institute of Social and Economic Research, Osaka University, including myself, have been conducting experiments to test theories regarding the provision of public goods. One of our more interesting findings to date is evidence among Japanese of a trait that can be described as "spite" in the way it impacts the provision of public goods. This paper describes the purposes, method, and some results of those experiments. We have been forced to ponder economic methodology in every phase of this project. We considered the methods of neo-classical economists such as Walras and Pareto, for example, who tended primarily to analyze data without concern for the motives behind strategic choices, and we examined the approach of those experimentalists who put forth questions only after finishing their tests. To develop our own methodology, therefore, it seemed reasonable and legitimate to pose questions midway through our experiments in order to elicit the factors behind strategic choices. That reasoning led to questions concerning the validity of behavioral assumptions made by neo-classical economists, moving us well away from Milton Friedman, who pays little attention to whether those assumptions are valid or not. In this way, experimentalists in this area, including ourselves, have begun to study behavior in terms of whether it is altruistic, spiteful, or fair in the provision of public goods. In our experiments, we found that the first priority for several subjects was not the total payoff amount they could expect to receive but the ranking among them. Comparing American subjects with Japanese, we found that the American subjects tended to behave as game theory would predict, while some Japanese subjects adopted 'spiteful' strategies initially and demonstrated cooperative behavior later. Today, we believe that understanding human behavior is the central issue in social science. Adam Smith, David Hume, and other eighteenth-century thinkers were interested in the sentiment and emotion behind economic decisions, but for a long time neoclassical economists of the last century effectively avoided the factor of motivation behind human behavior. By describing the experimental method, I hope that this paper will help to open a new and challenging path to understand human economic behavior and may contribute to the development of a new economics for this century.

One of the most distinguished features of Frank Knightʼs liberal thought seems to be his eco-nomic, political, and ethical criticisms both of the case for and against the free-enterprise com-petitive system. Through this multi-level, poly-angular analysis and on a resignation that the system appears as the best or “least worst” as possible human beings build on earth, Knight continued to identify many defects in the sys-tem, and disclose many absurdities in the way of thinking on which we rest unwittingly. For “menʼs errors,” he believed, “mostly lie in their premises, not in bad logic.” In this paper, I select the following five top-ics through which Knight repeatedly discussed our premises: (1) uneconomic aspect of compe-tition, (2) normative and conservative character of positive economics, (3) imaginary nature othe idea of natural rights, (4) self-deconstructive tendency of business and the power game, and (5) plural meanings of love in liberal society.This paper proposes that Knightʼs radical yet constructive criticisms aimed to refine, rather than advocate, the free-enterprise competitive system and warn against the fallacy of “absolut-ism: holding that a statement must be either true or false and that, if false, antithesis must be true.” So this essay not only destructs the image of Knight as a neo-classical economist, but also clarifies the differences and similarities between him and later Chicagoans. That is, it illuminates the contrary directions of their perspectives and the identical iconoclastic propensity for disclos-ing implicit postulates. JEL classification numbers: B 19, B 31, B 41.

The purpose of this paper is to show that Karl William Kappʼs theory of social costs is a part of the broader research field of social value theory and to clarify how he drew policy implications from the social value theory. Kapp argued that theories in mainstream economics related to ex-ternal diseconomies cannot be applied to phe-nomena like the occurrence of photochemical smog. This is because these phenomena are dis-continuous and nonlinear and cannot be fit into the framework of arithmetic, economic calcula-tions by firms. His theory of social value ex-plains such phenomena by using a model with dynamic interactions among multiple systems (physical, biological, and economic systems)and their subsystems. According to the theory, individual organisms and the economy exist in a holistic system, repeating metabolic processes and maintaining dynamic states of balance (or a disequilibrium steady state). Dynamic states of balance can be sustained as long as the scale of pollution or natural resource depletion is small; however, if the scale exceeds the threshold, dy-namic states of balance no longer hold. For this reason, Kapp advocated the setting of minimum tolerance limits (Mindesttoleranzgrenzen) that would be necessary for the continued existence of individual organisms and the economy.

The year 2012 marks the centennial anniversary of Milton Friedmanʼs birthday and the 50th an-niversary of the publication of Capitalism and Freedom (1962). This paper examines the his-torical significance of his contributions, by mainly reviewing the growing recent research on his economics. Friedman has been popularly described as the Chicago school, monetarist, market fundamentalist, and neo-liberal; I argue that it is necessary to examine these convention-al labels from a historical perspective. Friedman witnessed several and sometimes overlapping historical eras, and the paper focuses on the his-torical contexts of the following: economic sci-ence in the latter half of the twentieth century, the National Bureau of Economic Research tra-dition, the Chicago school research tradition, money and business cycle theories, the role and responsibility of public intellectuals, and the neo-liberalism movement. This paper arrives on the following conclusion. Friedmanʼs ideas drew upon the economics of mathematical and empir-ical nature, seen in the latter twentieth century, yet his approach deviated from the more domi-nant Cowles or MIT approaches, as he regarded economics as an applied and empirical policy science. His works shared common characteris-tics with the NBER tradition, and he changed the nature of the post-War Chicago school by importing the NBER tradition. His monetary and business cycle analysis is a mixture of old Chi-cago monetary tradition and the NBER tradition. His active role as a public intellectual was met with success and controversies, as did his in-volvement with the neo-liberal movement. Al-though Friedman should be primarily studied from a historical perspective, one cannot avoid reviewing his contributions only because he ex-erted a great influence on the history of econom-ics. This becomes more acute especially in the wake of the current economic and financial cri-sis. The paper primarily examines three ques-tions: whether Friedmanʼs ideas contributed to the current crisis, what Friedman would have done if he were alive, and what could be done to improve on Friedmanʼs contributions. The paper concludes that historians of economics would and should continue arguing about and with Friedman. JEL classification numbers: B20, B22, B31.

Abstract: This article aims to demonstrate Yuichi Shionoya’s theory of economic ethics by classifying his study into early, middle, and later stages and focusing on his conception of perfectionism. His theory is composed of ethics and economics. In early and later stages, Shionoya proposes his notion of ethics as one category of liberal perfectionism by demonstrating the relationship between the concepts of justice, goodness, and virtue. Part of its originality is that it is defined as being compatible with the pursuit of common good, which is the main purpose of welfare economics. Moreover, he proposes three kinds of economics: economic sociology, economic statics, and economic dynamics in the middle and later stages. He argues that a society in which liberal perfectionism prevails can be realized by the elitist method that he demonstrates in economic sociology. Thus, Shionoya attempts to construct his economic ethics as “universal social science” by integrating the ideas of political philosophy and welfare economics and showing consistency in his entire study. This article questions the consistency of Shionoya’s theory of economic ethics. The rest of this article is organized as follows. First, we classify Shionoya’s study and show that his main purpose is to construct an alternative theory by criticizing neoclassical economics. Second, we clarify his view of perfectionism by showing his ethical system. We then outline his theory of economic ethics by analyzing his economics and clarifying his method of institutional reform. Finally, we express doubt as to whether reform can lead to his concept of an ideal society. JEL classification numbers: B31, O31.

Abstract: Although the relationship between liberalism and his political thought has been emphasized, the classical aspect of his economic theories has been underestimated. This has, in my view, several reasons: To be sure, Ishibashi was one of those who had introduced Keynesian economics and his idea of positive fiscal policy. At the same tine, Ishibashi also admitted the rigidity of the market system. But this aspect of his economics did not prevent him to be committed to the classical economic theories, based on free market. It is characteristic of Ishibashi that these aspects existed together in theory and in practice. Based on this understanding, this paper attempts to reveal his optimism about price adjustment. This, in my understanding, led to his basic optimism about inflation. Thus, the study contributes to the better understanding of Ishibashi’s economic thought in particular and also to the better understanding of the many-layered disputes in his age in general. JEL classification number: B31.

This paper aims to review the scholarship on Adam Smithʼs The Wealth of Nations (WN) in the past decade. The publication of The Glasgow Edition of the Works and Correspondence of Adam Smith (1976―1987) led to the so-called “Adam Smith Renaissance” that has encouraged many scholars from different disciplines to con-duct interdisciplinary or multidisciplinary stud-ies on Smith. In addition to the studies on Scot-tish Enlightenment, the establishment of the In-ternational Adam Smith Society (IASS) in 1995 and the publication of the Adam Smith Review (ASR) in association with the IASS since 2004 further promoted interdisciplinary studies on Smith. Thus, the interdisciplinary wave of interest in Smithʼs moral philosophy is an outstanding feature of the latest scholarship on Smith. How-ever, as the interdisciplinary studies on Smith have advanced increasingly, there has been a definite waning of interest in his economics con-cerning WN. This phenomenon is indicated straightforwardly in Den Uyl (2008, 4) who mentions that “We can no longer say that WN is somehow the ʻessentialʼ Smith” and in Forman-Barzilai (2008, 219) who affirms that “Smithʼs political economy itself was not the centre on his thought, but rather its place in a lager project of moral philosophy.” Part I of this paper is a prologue to the man-ner in which the WN was studied in the past dec-ade. Part II discusses two excellent foreign works, Fleischackerʼs On Adam Smithʼs Wealth of Nations (2004) and Aspromourgosʼ The Sci-ence of Wealth (2009). These two books sharply contrast with each other, because the former has a philosophical approach to WN, while the latter adopts an orthodox style used by economic his-torians. Part III considers the scholarship on the WN in Japan. Inamuraʼs Reconsideration of the system of The Wealth of Nations (2003), Ta-jimaʼs Adam Smithʼs Institutional Economics (2003), and Takemotoʼs Across The Wealth of Nations (2005) will be mainly reviewed in this paper. In part III, I aim to ascertain the ortho-doxy of our scholarship on WN and its transfigu-ration in comparison with the scholarship abroad. Part IV, the epilogue, briefly surveys the origin of WN (Smithʼs political economy) in or-der to understand the nature of modern econom-ics. JEL classification number: B12, B31, A12.
