Maximum Probability method is used to translate possibly contiguous and overlapping categorical observations into frequencies.

This paper develops a set of management and production criteria needed to be used in order to maximize profits and shareholder values. If these criteria are achieved, the firm may achieve and sustain “supernormal” profits and revenue growth. The criteria developed here are all related to the...

There is much talk of the knowledge economy, and the central role of ideas and knowledge in generating economic growth. This paper provides a brief review of the economic literature on how skills/ knowledge/ ideas might contribute to higher output or higher rates of growth. Ideas are...

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...

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 explores whether habit formation in the representative agent’s preferences can explain two failures of the standard permanent income model: the sensitivity to lagged consumer sentiment, and to predictable changes in income. I show that in a habit formation model, the sensitivity of...

A simple framework is constructed and extended to consider the theory of investment. It shows that there exists in industrialized economies a certain structure that determines the balance curve, which relates the rates of inflation and capital accumulation if demand and productive capacity are...

Two results showing the limitations of the “as if” methodology are proved under relatively mild assumptions. In an interpretation of the results, a competitive market cannot simulate the outcome of a market M in which the single price assumption does not hold. In a second interpretation, the...
