During the past year the Euro-currency market played a very large role in bridging over the oil-induced payments imbalances. In the interest of international monetary stability this market should now move somewhat away from the centre of the stage and leave the main responsibility for the...

This paper focuses mainly on the impact of exchange rate changes in key currencies on the external debt of developing countries. It presents a systematic way of analysing the impact of a strongly depreciating U.S. dollar vis-a-vis other major currencies on the external debt of developing countries.

The general equilibrium models in this paper, with complete markets, can give the major features of business cycles. The models include real investment, but information is costless and is available to everyone at the same time. Fluctuations in the match between resources and wants across many...

When will the optimal mix of a constant income tax with a constant consumption tax involve a positive income tax? The assumptions of the model in which this question is asked include (1) identical individuals with coincident lifetimes who work in every period; (2) initial endowments of physical...

I believe that every tax-paying firm's defined benefit pension fund portfolio should be invested entirely in bonds (or insurance contracts). Although the firm's pension funds are legally distinct from the firm, there is a close tie between the performance of the pension fund investments and the...

In a one-period model where each investor consumes a single good, and where borrowing and lending are private and real, there is a universal constant that tells how much each investor hedges his foreign investments. The constant depends only on average risk tolerance across investors. The same...

Using a simple conventional model with additive separable utility and constant elasticity, we can explain mean reversion and consumption smoothing. The model uses the price of risk and wealth as state variables, but has only one stochastic variable. The price of risk rises temporarily as wealth...

The original cost regulatory system, as currently used in the regulation of utilities and natural gas pipelines, cannot emulate the response of a competitive firm to high and varying inflation. Although there can be many problems introduced by regulatory lag and by high administrative and...
