We consider model selection for non-linear dynamic equations with more candidate variables than observations, based on a general class of non-linear-in-the-variables functions, addressing possible location shifts by impulse-indicator saturation.  After an automatic search delivers a simplified...

This paper addresses the problem of estimating the aggregate international demand schedule for emerging market (EM) securities as an asset class. The standard ‘push-pull’ model of capital flows is modified by reference to recent work on portfolio choice in the context...

In an economy with a fixed exchange rate regime that suffers a random adverse shock, we study the strategies of imperfectly and sequentially informed speculators that may trigger an endogenous devaluation before it occurs exogenously. The game played by the speculators has a unique symmetric...

The swiftness and devastating impact of recent financial crises have taken many market participants by surprise, and pose challenges for economists seeking a theory of the onset of a crisis. We propose such a theory based on two features. The actions of diverse economic actors which undermine...

Analyses of the Asian crisis have focused excessively on the financial sector, especially the banks. The role of the real sector in exposing the financial system to stress has been under-emphasized. This paper provides a real-sector explanation for the Thai crisis of 1997, demonstrating the role...

Hurricanes in the Caribbean and Central America represent a natural experiment to test the intertemporal approach to current account determination. The intertemporal approach allows for the possibility of intertemporal trade, via international borrowing. Previous tests of intertemporal current...

Conditionality is the most controversial aspect of the IMF`s policies. It has been said to be intrusive and coercive and considered to disregard effects on growth, employment and income distribution. In the 1990s, following a sharp increase in the number of conditions required by programs, Fund...

We develop a new automatically-computable test for super exogeneity, using a variant of general-to-specific modeling.  Based on the recent developments of impulse saturation applied to marginal models under the null that no impulses matter, we select the significant impulses for testing in the...

Unpredictability arises from intrinsic stochastic variation, unexpected instances of outliers, and unanticipated extrinsic shifts of distributions.  We analyze their properties, relationships, and different effects on the three arenas in the title, which suggests considering three associated...

We develop forecast-error taxonomies when there are unmodeled variables, forecast 'off-line'.  We establish three surprising results.  Even when an open system is correctly specified in-sample with zero intercepts, despite known future values of strongly exogenous variables, changes in...
