Prevailing trade theory is a neglected stepchild of economics. Micro rejects the sole reason for trade’s occurrence. It declares zero profit in equilibrium. Monetary theory and macroeconomics dismiss concerns of trade financing. They assert that money has nothing to do with traded output, but...

Keynes (1936) said that shortage of money caused by hoarding or failure to invest led to unemployment, but Lucas (1972) said that money does not affect unemployment. The tables have now turned. Gani (2003) produced a model of indirect trade in which money is necessary as a means of payment....

This paper presents an estimated model with learning and provides evidence that learning can improve the fit of popular monetary DSGE models and endogenously generate realistic levels of persistence. The paper starts with an agnostic view, developing a model that nests learning and some of the...

This paper estimates a DSGE model with learning to re-examine the evidence on time variation in post-war U.S. monetary policy. Several papers document a regime switch, by showing that policy changed from `passive' and destabilizing in the pre-1979 period to `active' and stabilizing in the...

This paper investigates the dynamics of output, employment and prices in an economy with costs of adjusting labor and prices. In an economy with non convex adjustments costs, firms do not adjust labor and prices continuously to accommodate every shift in demand. Rather, firms adjust employment...

An analytical innovation enhances microeconomics, enabling it to answer all questions of macroeconomics. It combines the production and consumption decisions of the individual in one model. For each individual, it identifies the customers of what he sells, and the suppliers of what he buys. It...

SINCE 1930, EXPECTATIONS HAVE PLAYED AN IMPORTANT ROLE IN ECONOMIC THEORY AND THIS IS BECAUSE ECONOMICS IS GENERALLY CONCERNED WITH THE IMPLICATIONS OF CURRENT ACTIONS FOR THE FUTURE. THIS PAPER THEREFORE ARGUES THAT THE DEVELOPMENT OF RATIONAL EXPECTATIONS THEORY WILL MAKE A MORE SIGNIFICANT...

The paper explores the impacts of heterogeneity in degree of relative risk aversion on the balance on current account in a two-country endogenous growth model. It concludes that, like the heterogeneity of demographic changes, the heterogeneity in degree of relative risk aversion generates...

The paper explores an endogenous growth model in which scale effects asymptotically vanish and an economy grows without population growth. The key mechanism behind these features is substitution between investing in capital and in knowledge when firms face growing uncompensated knowledge...

In this paper I evaluate the contribution of R&D investments to productivity growth. The basis for the analysis are the free entry condition and the fact that most R&D innovations are embodied. Free entry yields a relationship between the resources devoted to R&D and the growth rate of...
