An equilibrium model of financial crises driven by Irving Fisher’s financial amplification mechanism features a pecuniary externality, because private agents do not internalize how the price of assets used for collateral respond to collective borrowing decisions, particularly when binding collateral constraints cause asset fire-sales and lead to a financial(More)
This paper revisits the issue of the optimal exchange rate regime in a flexible price environment. The key innovation is that we analyze this question in the context of environments where only a fraction of agents participate in asset market transactions (i.e., asset markets are segmented). We show that flexible exchange rates are optimal under monetary(More)
Recent declines in the U.S. current account and fiscal balances have sparked renewed debate over the twin-deficit hypothesis, which argues that a larger fiscal deficit, through its effect on national saving, leads to an expanded current account deficit. This study reviews international evidence on the hypothesis, finding some support for it. However, the(More)
We study a class of utility functions that are defined recursively by an aggregator W (x, y) where ut =W ( ct , ut+1 ) . In single-agent economies it is known that a sufficient condition for the existence of a balanced growth path is that utility should be homogenous of degree . In the context of a multiagent economy we show that this restriction implies(More)
Currency crises are not growth-neutral in the short-run. Nor are they necessarily contractionary. Even when they are associated with a contraction, the magnitude of contraction tends to vary significantly across episodes. Using a sample of 195 crisis episodes across 91 developing countries, this paper presents the main stylized facts on the behavior of(More)
Three features of the international exchange rate data that are widely known are: (a) a high correlation between bilateral nominal and real exchange rates; (b) real exchange rate movements are highly persistent; and (c) real exchange rates are highly volatile. This paper attempts a joint, albeit partial, rationalization of these facts in an environment with(More)
In this paper we discuss how several macroeconomic features of the 2001-2009 period may have resulted from a process in which financial markets were trying to allocate risk between heterogeneous agents when productive investment opportunities are scarce. We begin by showing how heterogeneity in terms of risk tolerance can cause financial markets to(More)
Development of an economy typically goes hand-in-hand with a declining importance of agriculture in output and employment. Given the primarily rural population in developing countries and their concentration in agrarian activities, this has potentially large implications for inequality along the development path. We examine this using the Indian experience(More)
We study the competitive equilibria of a two-country endogenous growth model in which the source of growth is the linearity of technology in reproducible inputs. We begin by showing that in a model with no externalities there is a unique equilibrium; however, there are multiple ways in which the social planner can allocate production plans across countries.(More)
