In this paper we build up a theoretical continuous time model to study how future constraints affect current investment decisions. We show that firms constrained in the future, but currently unconstrained, select an optimizing investment trajectory different from that of an identical firm that...

In this paper we show that the richest countries are investing proportionally less than middle income countries in engineering and technical human capital. We generalize this result, controlling for country-specific effects, cross-time error correlations, heteroskedasticity, the presence of...

Two-country applications of equilibrium business cycle methodology have succeeded in matching some key features of international fluctuations. However, discrepancies between theory and data remain. This paper identifies an anomaly related to a basic property of typical models: The prediction of...

The annual structure of real output in the G7 countries is investigated in this article by means of fractional integration techniques. However, instead of using the classical ARMA specifications for describing the short-run components of the series, we use an approach due to Bloomfield (1973)....

In this paper we build up a theoretical continuous time model to study how future constraints affect current investment decisions. We show that firms constrained in the future, but currently unconstrained, select an optimizing investment trajectory different from that of an identical firm that...

New growth theories suffer from their counterfactual prediction that a higher (rate of) population (growth) generally implies a higher growth rate of per capita income. This population puzzle is solved by introducing imported intermediates and an exogenously growing world export demand creating...

This paper develops a simple model to study the impact of stock markets on the current account. The model allows for an arbitrary number of risky assets, which form an incomplete market, as well as a risk-free bond. A closed-form solution for the current account is derived from the optimal...

The Federal Reserve Act calls upon the newly created Banks "... to furnish an elastic currency..." since such action was thought to be welfare improving during times of high currency demand. This paper considers the welfare implications of an "elastic currency" regime within the context of an...

If technological innovations in the North can be costlessly imitated by educated workers in the South, and if education decisions are endogenous, why aren't all countries well-educated and rich? This paper explores a possible answer: if technologically advanced sectors, operating under...
