"Sudden Stops " experienced during emerging markets crises are characterized by large reversals of capital inflows and the current account, deep recessions, and collapses in asset prices. This paper proposes an open-economy equilibrium asset pricing model in which financial frictions cause Sudden Stops. Margin requirements impose a collateral constraint on foreign borrowing by domestic agents and trading costs distort asset trading by foreign securities firms. At equilibrium, margin constraints may or may not bind depending on portfolio decisions and equilibrium asset prices. If margin constraints do not bind, productivity shocks cause a moderate fall in consumption and a widening current account deficit. If debt is high relative to asset holdings, the same productivity shocks trigger margin calls forcing domestic agents to fire-sell equity to foreign traders. This sets off a Fisherian asset-price deflation and subsequent rounds of margin calls. A current account reversal and a collapse in consumption occur when equity sales cannot prevent a sharp rise in net foreign assets.

This paper is part of a project to model the interaction between heterogeneous agents in intertemporal stochastic models and to develop numerical algorithms to solve these kind of models. It is well-known that solving dynamic heterogeneous agent models is a challenging problem, since in these models the distribution of wealth and other characteristics evolve endogenously over time. Existing dynamic models in the literature contain therefore just two agents or other simplifying assumptions to limit the heterogeneity.

Creator: Townsend, Robert M., 1948- Series: Financial history conference Abstract:
ln environments with private information and spatial separation, the ability of agents to establish mutually beneficial arrangements can be limited by their ability to communicate contemporary dealings and histories of past dealings. Indeed, with the extension of some recent work in contract theory and mechanism design, this paper argues that location or person-specific assignment systems, portable object record-keeping systems, written message systems, and telecommunication systems can be viewed as communication systems which are successively more complete in this sense. An attempt is made also to match these various communication systems with systems in use in historical primitive, and/or contemporary societies and to interpret these communication systems as financial structures.

Creator: Boot, Arnoud W. A. (Willem Alexander), 1960-, Greenbaum, Stuart I., and Thakor, Anjan V. Series: Monetary theory and financial intermediation Abstract:
We explain why contracting parties may choose ambiguous financial contracts. Introducing ambiguity may be optimal, even when unambiguous contracts can be costlessly written. We show that an ambiguous contract has two advantages. First, it permits the guarantor to sacrifice reputational capital in order to preserve financial capital as well as information reusability in states where such tradeoff is optimal. Second, it fosters the development of reputation. This theory is then used to explain ambiguity in mutual fund contracts, bank loan commitments, bank holding company relationships, the investment banker's "highly confident" letter, non-recourse debt contracts in project financing, and other financial contracts.

Creator: Baxter, Marianne, 1956- Series: Nonlinear rational expectations modeling group Abstract:
This paper develops a new method for approximating dynamic competitive equilibria in economies in which competitive equilibrium is not necessarily Pareto optimal. The method involves finding approximate equilibrium policy functions by iterating on the stochastic Euler equations which characterize the economy's equilibrium. Two applications are presented: the stochastic growth model of Brock and Mirman (1971) modified to allow distortionary taxation, and a model of inflation and capital accumulation based on Stockman (1981). The computational speed and accuracy of this approach suggests that it may be a feasible method for studying suboptimal economies with large state spaces.

Creator: Barbosa, Antonio S. Pinto., Jovanovic, Boyan, 1951-, and Spiegel, Mark. Series: Conference on economics and politics Abstract:
This paper analyzes how political stability depends on economic factors. Fluctuations in groups' economic capacities and in their abilities to engage in rent-seeking or predatory behavior create periodic incentives for those groups to renege on their social obligations. A constitution remains in force so long as no party wishes to defect to the noncooperative situation, and it is reinstituted as soon as each party finds it to its advantage to revert to cooperation. Partnerships of equals are easier to sustain than are arrangements in which one party is more powerful in some economic or noneconomic trait. In this sense, inequality is bad for social welfare. Surprisingly, perhaps, it is the rich, and not the poor segments of society who in our model pose the greater threat to the stability of the social order. Using cross-country data, we test and confirm the prediction that most constitutional disruptions should be accompanied by increases in income inequality.

Creator: Bryant, John B. Series: Working paper (Federal Reserve Bank of Minneapolis. Research Department) Number: 168 Abstract:
A simple model of backed money without a store of value function is presented, discussed, and defended. The function of money in the model is to replace complex contingent contracts traded on a centralized exchange with simple trades in decentralized markets.
