This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

We characterize the equilibrium exchange rate in a general equilibrium economy without imposing strong restrictions on the output processes, preferences, or commodity market imperfections. The nominal exchange rate is determined by differences in initial wealths the currencies of richer...

Few sovereign debtors have repudiated their obligations entirely. But despite the significant sanctions at the disposal of lenders, many borrowers have been able to consistently negotiate for reduced repayments. This paper presents a model of the on-going bargaining process that determines...

A decision maker (DM) determines a set of reactions that receivers can choose before senders and receivers move in a generalized competitive signaling model with two-sided matching. The DM’s optimal design of the unique stronger monotone signaling equilibrium (unique D1 equilibrium) is...

A two-period model of temporary equilibrium with rationing is presented, paying particular attention to agents' expectations of future constraints. it is shown that with arbitrary constraint expectations many different types of current equilibria may be consistent with the same set of (current...

In this paper, we investigate the descriptive and normative properties of competitive equilibrium with moral hazard when firms offer "price contracts" which allow clients to purchase as much insurance as they wish at the quoted prices. We show that a price equilibrium always exists and is one of...

The paper reviews theoretical developments in the field of exchange rate theory and assesses the empirical evidence. Since the empirical evidence does not lend support to the models that have been formulated, a number of reasons for that failure are suggested. These include the argument that the...

This paper investigates the existence of unique equilibrium in two-good economies where agents have preferences with the same relative risk aversion and different utility weights. Aggregate demand behavior is characterized in terms of both macrolevel and micro-level information inherent in the...

This paper exposits the modern theory of equalizing differences,viewed as optimal assignments of workers to jobs. The basic ideas are first illustrated in a simple model with binary choices of work attributes.Multinominal choices are briefly considered after that. Empirical implications are...

This paper provides a choice theoretic, general equilibriumaccount of the balance of payments adjustment process and the determinationof national price levels in a world comprised of countries populated byrational households. Balance of payments adjustment dynaniics arise in theequilibrium of...

This study demonstrates how constrained efficient allocations can arise endogenously as equilibria in an economy with a limited ability to enforce contracts and with private agents behaving competitively, taking a set of taxes as given. The taxes in this economy limit risk-sharing and arise in...

We study a pure-exchange incomplete-market economy with heterogeneous agents. In each period, the agents choose how much to save (i.e., invest in a risk-free bond), how much to consume, and which bundle of goods to consume while their endowments are fluctuating. We focus on a competitive...

Equilibrium notions for games with unawareness in the literature cannot be interpreted as steady-states of a learning process because players may discover novel actions during play. In this sense, many games with unawareness are "self-destroying" as a player's representation of the game may...

We study the assignment of discrete resources in a general model encompassing a wide range of applied environments, such as school choice, course allocation, and refugee resettlement. We allow single-unit and general multi-unit demands and any linear constraints. We prove the Second Welfare...

Harris, Reny, and Robson (1995) added a public randomization device to dynamic games with almost perfect information to ensure existence of subgame perfect equilibria (SPE). We show that when Nature's moves are atomless in the original game, public randomization does not enlarge the set of SPE...

This paper mainly studies two topics: linear complementarity problems for modeling electricity market equilibria and optimization under uncertainty. We consider both perfectly competitive and Nash-Cournot models of electricity markets and study their robustifications using strict robustness and...

This paper proposes an equilibrium theory of nominal exchange rates, which offers a new perspective on various issues in open economy macroeconomics. The nominal exchange rate and portfolio choices are jointly determined in equilibrium, thus providing a new approach to overcoming the...

Previous equilibrium "business cycle" models are extended by the incorporation of an economy-wide capital market. One aspect of this ex-tension is that the relative price that appears in commodity supply and demand functions becomes an anticipated real rate of return on earning assets, rather...

We study the assignment of discrete resources in a general model encompassing a wide range of applied environments, such as school choice, course allocation, and refugee resettlement. We allow single-unit and general multi-unit demands and any linear constraints. We prove the Second Welfare...

This paper compares the financing of new ventures in start-ups (entrepreneurship) and in established firms (intrapreneurship). Intrapreneurship allows established firms to use information on failed intrapreneurs to redeploy them into other jobs. By contrast, failed entrepreneurs must seek other...

A nonstandard counterpart to the results of Allen and Hellwig (1986) on the convergence of a Bertrand-Edgeworth equilibrium arising out of price setting by firms operating under capacity constraint into a Walrasian (or competitive) equilibrium is presented and analyzed

We study the conditions under which input-output networks can dynamically attain competitive equilibrium, where markets clear and profits are zero. We endow a classical firm network model with simple dynamical rules that reduce supply/demand imbalances and excess profits. We show that the time...

This paper analyzes the determination of the optimal tariff under the assumption of Consistent Conjectural Variations (CCV). A general characterization of the CCV equilibrium is given. We show that (i) there are, in general, a multiplicity of such equilibria, and (ii) under certain restrictions,...

We develop a theory of "Partial Equilibrium Thinking" (PET), whereby agents fail to understand the general equilibrium consequences of their actions when inferring information from endogenous outcomes. PET generates a two-way feedback effect between outcomes and beliefs, which can lead to...

Purpose - The purpose of this paper is to study the Hölder calmness of solutions to equilibrium problems and apply it to economics. Design/methodology/approach - The authors obtain the Hölder calmness by using an effective approach. More precisely, under the key assumption of strong convexity,...

We offer an equilibrium model of cryptocurrency pricing and confront it to new data on bitcoin transactional benefits and costs. The model emphasises that the fundamental value of the cryptocurrency is the stream of net transactional benefits it will provide, which depend on its future prices....

In this paper, I study the existence and uniqueness of recursive equilibria in economies with aggregate and idiosyncratic risk. Rather than relying on compactness to establish existence, I exploit the monotonicity property of the equilibrium model and rely on arguments from convex analysis. This...

Hayek was among the first to realize that for intertemporal equilibrium to obtain all agents must have correct expectations of future prices. Before comparing four categories of intertemporal, the paper explains Hayek's distinction between correct expectations and perfect foresight. The four...

We investigate competitive equilibria in a special type of incomplete markets, referred to as a comonotone market, where agents can only trade such that their risk allocation is comonotonic. The comonotone market is motivated by the no-sabotage condition. For instance, in a standard insurance...

We study the monotonicity of sender's equilibrium strategy with respect to her type in signalling games. We use counterexamples to show that when the sender's payoff is non-separable, the Spence-Mirrlees condition cannot rule out equilibria in which the sender uses non-monotone strategies. These...

Firms launch formal programs to identify promising employee ideas and to provide support for their commercialization. This paper examines an alternative role of the firm's internal screening process in employee turnover. I argue that because the firm has better information vis-à-vis the market...

In~[1], authors consider a general model of dynamic game of asymmetric information, where N players have types evolving as independent Markovian process, where each player observes its own type perfectly and actions of all players. The authors present a sequential decomposition algorithm to find...
