Players take costly actions to affect the evolution of state variables that are commonly observable and perturbed by Brownian noise. The values of these state variables influence players' terminal payoffs at the deadline, as well as their flow payoffs. In contrast to the static case, the equilibrium is unique under a general class of terminal payoff functions. Our characterization of the equilibrium builds on recent developments in the theory of backward stochastic differential equations (BSDEs). We use this tool to analyze applications, including team production, hold-up problems, and dynamic contests. In a team production model, the unique equilibrium selects an efficient outcome when frictions vanish. “Comparative Measures of Naiveté” (with David S.

Hysteresis in Dynamic General Equilibrium Models with Cash-in-Advance Constraints¤ Kazuya Kamiyayand Takashi Shimizuz October 2010 Abstract In this paper, we investigate equilibrium cycles in dynamic general equilibrium models with cash-in-advance constraints. Our findings are two-fold. First, in such models, if an equilibrium cycle exists, then there also exists a continuum of equilibrium cycles in its neighborhood. Second, the limit cycle, to which a dynamic path converges, varies continuously according to the initial distribution of the money holdings. Thus, temporary shocks that affect the initial distribution have permanent effects in such models; that is, such models exhibit hysteresis. Furthermore, we also explore the logic behind the results. Keywords: Dynamic General Equilibrium Models, Cash-in-Advance, Cycles, Hysteresis. JEL Classification Number: D51, E40, E50, E60. 1 Introduction In this paper, we investigate equilibrium cycles in dynamic general equilibrium models with cash- in-advance constraints, wherein each agent’s money holding varies over time. We first show that a continuum of equilibrium cycles exists in a specific model with cash-in-advance constraints, and that the limit cycle, to which a dynamic path converges, varies continuously according to the initial distribution of money holdings.

  • Liquidity: a New Monetarist Perspective∗
    Liquidity: A New Monetarist Perspective∗ Ricardo Lagos Guillaume Rocheteau NYU UC-Irvine Randall Wright UW-Madison, FRB Minneapolis, FRB Chicago, and NBER August 19, 2015 Abstract This essay surveys the New Monetarist approach to liquidity. Work in this literature strives for empirical and policy relevance, plus rigorous foundations. Questions include: What is liquidity? Is money essential in achieving desir- able outcomes? Which objects can or should serve in this capacity? When can asset prices differ from fundamentals? What are the functions of com- mitment and collateral in credit markets? How does money interact with credit and intermediation? How can and should monetary policy do? The re- search summarized emphasizes the micro structure of frictional transactions, and studies how institutions like monetary exchange, credit arrangements or intermediation facilitate the process. ∗A previous version of this essay circulated as “The Art of Monetary Theory: A New Mon- etarist Perspective” (to pay homage to Clarida et al. 1999).

On the Role of Tax-Subsidy Scheme in Money Search Models∗ Kazuya Kamiya†and Takashi Shimizu‡ March 2005 Abstract This paper investigates the role of policy in money search models with divisible money. Recently, real indeterminacy of stationary equilibria has been found in both specific and general search models with divisible money. Thus if we assume the divisibility of money, it would be quite difficult to make accurate predictions of the effects of simple monetary policies. Instead, we show that some tax-subsidy schemes select a determinate efficient equilibrium. In other words, for a given efficient equilibrium and for any real number δ>0, a certain tax-subsidy scheme induces a locally determinate equilibrium within the δ-neighborhood of the given equilibrium.

This is a natural random decentralized dynamic compet- itive process. We show that this process converges globally and almost surely to a competitive equilibrium. This result is surprisingly general by assuming only the existence of an equilibrium. Our findings have also meaningful policy implications.
