Did the debt crisis cause the investment crisis?
There is now a large literature which attributes the investment decline in heavily indebted developing countries to the effects of the international debt crisis which began in 1982. However, these theories have not been tested against the alternative that declining terms of trade and high world real interest rates in the early 1980s directly caused the investment declines. This paper is based on the idea that if the debt theories are true, then forecasts of investment in the 1980s which do not use debt variables should not perform very well. This paper points out that such forecasts perform ...

Import demand and supply with relatively few theoretical or empirical puzzles
This paper documents that a textbook, supply and demand, simultaneous equations model of import prices and quantities can explain many aspects of import price and quantity behavior over the past 25 years, appears to forecast better than standard trade equations, and the instruments we use appear to be valid instruments. On the negative side, although the demand equation and the two reduced form equations satisfy nominal homogeneity restrictions, the supply equation does not. One possible explanation for this is that foreign suppliers do not believe that exchange rate shocks have the same ...

Did the debt crisis or the oil price decline cause Mexico's investment collapse?
This paper proposes a simple investment model that permits a test of the relative importance of Mexico's terms of trade decline, the reversal in net capital inflows, and the debt overhang, in explaining Mexico's investment decline in the early 1980's. The paper uses previously unexploited sectoral investment data between 1981 and 1985 to estimate the quantitative importance of these explanations. The data indicate that the main microeconomic mechanism driving the investment decline was the rise in the relative price of investment goods and further that the deterioration in Mexico's ...

Does world investment demand determine U.S. exports?
An important but apparently neglected fact about U.S. exports is that export variation over time is dominated by variation in exports of capital goods and industrial supplies rather than consumer goods. This fact suggests that world investment demand rather than world consumption demand may be an important yet neglected determinant of U.S. exports. This paper documents a remarkably robust statistical relationship between U.S. exports and world investment demand, and shows that controlling for world investment changes other aspects of traditional export demand equations. To the extent that ...
