We use stochastic optimal control-dynamic programming (DP) to derive the optimal foreign debt/net worth, consumption/net worth, current account/net worth, and endogenous growth rate in an open economy. Unlike the literature that uses an Intertemporal Budget Constraint (IBC) or the Maximum...

In this paper we characterize empirically the comovements of macro variables typically observed in middle income countries, as well as the boom-bust cycle that has been observed during the last two decades. We find that many countries that have liberalized their financial markets, have witnessed...

In this paper we document three credit market imperfections prevalent in middle income countries that can help to explain boom-bust cycles, as well as other macroeconomic patterns observed at higher frequencies across these countries. These imperfections are: the existence of financing...

What is an optimal or a sustainable external debt - for a country, region or sector? How should one monitor and evaluate debt to preclude a crisis? We use stochastic optimal control/dynamic programming to derive an optimal debt. The deviation of the actual from the optimal will serve as a...

In this paper we analyse debt stabilization in a monetary union that features endogenous risk premia. In particular, we analyse debt stabilization in two diametrically opposed regimes. In the first regime, the "national fiscal discipline regime", financial markets impose sovereign risk premia...

The recent financial crises, especially the debt crisis in Asia, have led to questions su ch as: what are their causes, what is an excessive debt and how vulnerable is an economy to external shocks? We develop an economic model of international finance and debt based upon two sources of...

Sovereign governments owe debt to many foreign creditors and can choose which creditors to favor when making payments. This paper documents the de facto seniority structure of sovereign debt using new data on defaults (missed payments or arrears) and creditor losses in debt restructuring...

We add to the literature on the influence of the global financial cycle (GFC) and gyrations in capital flows. First, we build a new measure of the GFC based on a structural factor approach, which incorporates theoretical priors in its definition. This measure can also be decomposed in a...

What went wrong? Why did seemingly rational bond investors continue to purchase Puerto Rican debt with only a modest risk premium, even though the macroeconomic fundamentals were dismal? Why did financial markets fail to exercise market discipline and restrict capital flows to Puerto Rico? Given...

The controversy about sovereign debt cuts loomed prominently throughout crisis in the European Union (EU), as the EU legal rules were viewed to impose strict limitations on debt restructuring involving public creditors due to moral hazard concerns enshrined in the legal ban on bailouts. This...
