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...

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...

The post-1945 mode of global integration has outlived its early promise. It has become exploitative rather than supportive of capital investment, public infrastructure, and living standards. In the sphere of trade, countries need to rebuild their self-sufficiency in food grains and other basic...

Using bank-specific data on U.S. bank claims on individual foreign countries since the mid-1980s, this paper 1) characterizes the size and portfolio diversification patterns of the U.S. banks engaging in foreign lending, and 2) econometrically explores the determinants of fluctuations in U.S....

Much has changed in international finance in the twenty years since UNU-WIDER was founded. This paper identifies five broad contours of what we might expect in the next twenty years: the flow of capital from ageing societies to the more youthful economies of the South; the growth in the...

The level, tenor and instability of capital flows from global financial markets towards developing countries are a major source of concern for macroeconomic managers, while their causes remain largely unexplained by economic theory. Country ‘fundamentals’ (such as economic growth, monetary...

This paper investigates the sources of both foreign exchange rate and interest rate exposure of industry level portfolios in the G7, decomposing exposure into cash flow and discount rate effects. Initial examination of the degree of exposure on industry returns produces results consistent with...

This paper investigates the impact of exchange rate fluctuations on the value of nonfinancial firms in Chile. Using a detailed dataset on firms' foreign activities, the potential determinants of the identified exposure are examined. Foreign exchange exposure depends on the levels of foreign...
