A Macroeconomic Model with Financial Panics Mark Gertler, Nobuhiro Kiyotaki and Andrea Prestipino NYU, Princeton and Federal Reserve Board December, 2017 Abstract This paper incorporates banks and banking panics within a conven- tional macroeconomic framework to analyze the dynamics of a financial crisis of the kind recently experienced. We are particularly interested in characterizing the sudden and discrete nature of the banking panics as well as the circumstances that makes an economy vulnerable to such panics in some instances but not in others. Having a conventional macroeconomic model allows us to study the channels by which the crisis a¤ects real activity and the e¤ects of policies in containing crises. -

The Devil is in the Details – Implications of Samuel Bowles’ The Moral Economy for economics and policy research October 13 2017 Rachel Kranton Duke University The Moral Economy by Samuel Bowles should be required reading by all graduate students in economics. Indeed, all economists should buy a copy and read it. The book is a stunning, critical discussion of the interplay between economic incentives and preferences. It challenges basic premises of economic theory and questions policy recommendations based on these theories. The book proposes the path forward: designing policy that combines incentives and moral appeals. And, therefore, like such as book should, The Moral Economy leaves us with much work to do. The Moral Economy concerns individual choices and economic policy, particularly microeconomic policies with goals to enhance the collective good. The book takes aim at laws, policies, and business practices that are based on the classic Homo economicus model of individual choice. The book first argues in great detail that policies that follow from the Homo economicus paradigm can backfire. While most economists would now recognize that people are not purely selfish and self-interested, The Moral Economy goes one step further. Incentives can amplify the selfishness of individuals. People might act in more self-interested ways in a system based on incentives and rewards than they would in the absence of such inducements. The Moral Economy warns economists to be especially wary of incentives because social norms, like norms of trust and honesty, are critical to economic activity. The danger is not only of incentives backfiring in a single instance; monetary incentives can generally erode ethical and moral codes and social motivations people can have towards each other. -

Monetary Policy Rules and Macroeconomic Stability: Evidence and Some Theory*
MONETARY POLICY RULES AND MACROECONOMIC STABILITY: EVIDENCE AND SOME THEORY* RICHARD CLARIDA JORDI GALI´ MARK GERTLER We estimate a forward-looking monetary policy reaction function for the postwar United States economy, before and after Volcker’s appointment as Fed Chairman in 1979. Our results point to substantial differences in the estimated rule across periods. In particular, interest rate policy in the Volcker-Greenspan period appears to have been much more sensitive to changes in expected ination than in the pre-Volcker period. We then compare some of the implications of the estimated rules for the equilibrium properties of ination and output, using a simple macroeconomic model, and show that the Volcker-Greenspan rule is stabilizing. I. INTRODUCTION From the late 1960s through the early 1980s, the United States economy experienced high and volatile ination along with several severe recessions. Since the early 1980s, however, ina- tion has remained steadily low, while output growth has been relatively stable. Many economists cite supply shocks—and oil price shocks, in particular—as the main force underlying the instability of the earlier period. It is unlikely, however, that supply shocks alone could account for the observed differences between the two eras. For example, while jumps in the price of oil might help explain transitory periods of sharp increases in the general price level, it is not clear how they alone could explain persistent high ination in the absence of an accommodating monetary policy.1 Furthermore, as De Long {1997} argues, the onset of sustained high ination occurred prior to the oil crisis episodes. * We thank seminar participants at Universitat Pompeu Fabra, New York University, the Board of Governors of the Federal Reserve System, University of Maryland, NBER Summer Institute, Universite´ de Toulouse, Bank of Spain, Harvard University, Bank of Mexico, Universitat de Girona, and the Federal Reserve Banks of Atlanta, New York, Richmond, Dallas, and Philadelphia, as well as two anonymous referees and two editors for useful comments. -
Analyzing Just-In-Time Purchasing Strategy in Supply Chains Using an Evolutionary Game Approach
Bulletin of the JSME Vol.14, No.5, 2020 Journal of Advanced Mechanical Design, Systems, and Manufacturing Analyzing just-in-time purchasing strategy in supply chains using an evolutionary game approach Ziang LIU* and Tatsushi NISHI** *Graduate School of Engineering Science, Osaka University 1-3 Machikaneyama-Cho, Toyonaka City, Osaka 560-8531, Japan E-mail: [email protected] **Graduate School of Natural Science and Technology, Okayama University 3-1-1 Tsushima-naka, Kita-ku, Okayama City, Okayama 700-8530, Japan Received: 18 December 2019; Revised: 30 March 2020; Accepted: 9 April 2020 Abstract Many researchers have focused on the comparison between the JIT model and the EOQ model. However, few of them studied this problem from an evolutionary perspective. In this paper, a JIT purchasing with the single- setup-multi-delivery model is introduced to compare the total costs of the JIT model and the EOQ model. Also, we extend the classical JIT-EOQ models to a two-echelon supply chain which consists of one manufacturer and one supplier. Considering the bounded rationality of players and the quickly changing market, an evolutionary game model is proposed to discuss how these factors impact the strategy selection of the companies. And the evolutionarily stable strategy of the proposed model is analyzed. Based on the analysis, we derive the conditions when the supply chain system will choose the JIT strategy and propose a contract method to ensure that the system converges to the JIT strategy. Several numerical experiments are provided to observe the JIT and EOQ purchasing strategy selection of the manufacturer and the supplier. -
Kahneman's Thinking, Fast and Slow from the Standpoint of Old
Kahneman’s Thinking, Fast and Slow from the Standpoint of Old Behavioural Economics (For the 2012 HETSA Conference) Peter E. Earl School of Economics, University of Queensland, St Lucia, Brisbane, QLD 4072, Australia, email: [email protected] Abstract Daniel Kahneman’s bestseller Thinking, Fast and Slow presents an account of his life’s work on judgment and decision-making (much of it conducted with Amos Tversky) that has been instrumental in the rise of what Sent (2004) calls ‘new behavioural economics’. This paper examines the relationship between Kahneman’s work and some key contributions within the ‘old behavioural’ literature that Kahneman fails to discuss. It show how closely aligned he is to economic orthodoxy, examining his selective use of Herbert Simon’s work in relation to his ‘two systems’ view of decision making and showing how Shackle’s model of choice under uncertainty provided an alternative way of dealing with some of the issues that Kahneman and Tversky sought to address, three decades after Shackle worked out his model, via their Prospect Theory. Aside from not including ‘loss aversion’, it was Shackle’s model that was the more original and philosophically well-founded. Keywords: Prospect Theory, satisficing, bounded rationality, choice under uncertainty JEL Classification Codes: B31, D03, D81 1. Introduction In his highly successful 2011 book Thinking, Fast and Slow Daniel Kahneman offers an excellent account of his career-long research on judgment and decision- making, much of it conducted with the late Amos Tversky. Kahneman was awarded the 2002 Bank of Sweden PriZe in Economic Sciences in Memory of Alfred Nobel for this work. -
Dynamic Games Under Bounded Rationality
Munich Personal RePEc Archive Dynamic Games under Bounded Rationality Zhao, Guo Southwest University for Nationalities 8 March 2015 Online at https://mpra.ub.uni-muenchen.de/62688/ MPRA Paper No. 62688, posted 09 Mar 2015 08:52 UTC Dynamic Games under Bounded Rationality By ZHAO GUO I propose a dynamic game model that is consistent with the paradigm of bounded rationality. Its main advantages over the traditional approach based on perfect rationality are that: (1) the strategy space is a chain-complete partially ordered set; (2) the response function is certain order-preserving map on strategy space; (3) the evolution of economic system can be described by the Dynamical System defined by the response function under iteration; (4) the existence of pure-strategy Nash equilibria can be guaranteed by fixed point theorems for ordered structures, rather than topological structures. This preference-response framework liberates economics from the utility concept, and constitutes a marriage of normal-form and extensive-form games. Among the common assumptions of classical existence theorems for competitive equilibrium, one is central. That is, individuals are assumed to have perfect rationality, so as to maximize their utilities (payoffs in game theoretic usage). With perfect rationality and perfect competition, the competitive equilibrium is completely determined, and the equilibrium depends only on their goals and their environments. With perfect rationality and perfect competition, the classical economic theory turns out to be deductive theory that requires almost no contact with empirical data once its assumptions are accepted as axioms (see Simon 1959).

This paper offers a consolidated pre- sentation of a theory of bounded rationality based on information-theoretic ideas. We provide a conceptual justification for using the free energy functional as the objective func- tion for characterizing bounded-rational decisions. This functional possesses three crucial properties: it controls the size of the solution space; it has Monte Carlo planners that are exact, yet bypass the need for exhaustive search; and it captures model uncertainty arising from lack of evidence or from interacting with other agents having unknown intentions. We discuss the single-step decision-making case, and show how to extend it to sequential decisions using equivalence transformations. This extension yields a very general class of decision problems that encompass classical decision rules (e.g. Expectimax and Minimax) as limit cases, as well as trust- and risk-sensitive planning. arXiv:1512.06789v1 [stat.ML] 21 Dec 2015 c December 2015 by the authors. -
Imbalanced Collusive Security Games
Imbalanced Collusive Security Games Han-Ching Ou, Milind Tambe, Bistra Dilkina, and Phebe Vayanos Computer Science Department, University of Southern California {hanchino,tambe,dilkina,phebe.vayanos }@usc.edu Abstract. Colluding adversaries is a crucial challenge for defenders in many real-world applications. Previous literature has provided Collusive Security Games (COSG) to model colluding adversaries, and provided models and algorithms to generate defender strategies to counter colluding adversaries, often by devising strategies that inhibit collusion [6]. Unfortunately, this previous work focused exclusively on situations with perfectly matched adversaries, i.e., where their rewards were symmetrically distributed. In the real world, however, defenders often face adversaries where their rewards are asymmetrically distributed. Such inherent asymmetry raises a question as to whether human adversaries would at- tempt to collude in such situations, and whether defender strategies to counter such collusion should focus on inhibiting collusion. To address these open ques- tions, this paper: (i) explores and theoretically analyzes Imbalanced Collusive Security Games (ICOSG) where defenders face adversaries with asymmetrically distributed rewards; (ii) conducts extensive experiments of three different adver- sary models involving 1800 real human subjects and (iii) derives novel analysis of the reason behind why bounded rational attackers models outperform perfectly rational attackers models. The key principle discovered as the result of our -

Holt University of Virginia, Charlottesville, VA 22903-3328, USA [email protected] PROOF Abstract We specify a dynamic model in which agents adjust their decisions toward higher payoffs, subject to normal error. This process generates a probability distribution of players’ decisions that evolves over time according to the Fokker–Planck equation. The dynamic process is stable for all potential games, a class of payoff structures that includes several widely studied games. In equilibrium, the distributions that determine expected payoffs correspond to the distributions that arise from the logit function applied to those expected payoffs. This ‘‘logit equilibrium’’ forms a stochastic generalization of the Nash equilibrium and provides a possible explanation of anomalous laboratory data.

Relation Exchange As the Model of Bounded Rationality
Relation exchange as the model of bounded rationality June 16, 2017 Sung Sup Rhee Emeritus professor at Soongsil University [email protected] This paper is a preliminary version which is prepared for the presentation at 2017 KEA- APEA conference, July 7-8, 2017. Title: Relation exchange as the model of bounded rationality Author: Sung Sup Rhee/Emeritus professor at Soongsil University/[email protected] Abstracts: Kahneman (2003) presented the scheme of human cognitive system, which presents the steps of sensory order. Human cognition begins with perceptions, from which intuition comes off as fast, parallel, automatic, effortless and emotional system. Reasoning is slow, serial, controlled, effortful and rule-governed system of cognition. The architecture of rational agent model is built on the unrealistic assumption of single cognitive system which has the logical ability of a flawless system of reasoning. However, upon encountering the need to make decision, individuals are likely to act intuitively because intuition is more accessible than reason, which is at odds with the premise of rational agent model and prompts the launching of empiricism approach (Hume 1739). The process of sympathy and consent may be considered as the conduit between different cognitive systems of different individuals. Then, the relational interactions among individuals, i.e. relation exchange should be conceived as the outcome of sympathy-consent process (Rhee 2012b, 2016b). The fundamentality of relation exchange in comparison with value exchange vindicates the legitimacy of relation exchange as the model of bounded rationality.
