The paper analyses how barriers to communication across social groups affect economy-wide productivity and factor accumulation. Using a dynamic model of an economy that includes a reproducible capital stock (physical or human) and effective labour, social barriers to communication are shown to...

This paper models the supply of perishable goods within a randon framework. Perishability affects a large group of goods usually traded in the economy such as fruits and vegetables, newspapers, medicine drugs, a.s.o.. Surprisingly, one cannot find in the literature a decision model for suppliers...

In 1943, Paul Rosenstein-Rodan first coined the term “big-push†in his paper about growth in Eastern European economies. In 1989, Murphy et al. characterised the big-push as a static multi-equilibrium aggregate demand spillover model. Based on the model with a factory wage premium by...

Researchers have incorporated labor or credit market frictions in isolation within simple neoclassical models to open up a role for institutions, inject realism into their models and examine the impact of these distortions on output and employment. We present an overlapping generations model...

We study the effects of human capital homogeneity on economic growth with a two-sector model. We model the difference in human capital via a varying efficiency of individual agents in human capital production, alternatively education. Even though mean value of the education efficiency is the...

The market value of U.S. corporations, relative to the replacement cost of their tangible assets, declined by about 50% in 1973-74, and stagnated at that level for the following decade. This collapse in market valuations exactly coincides with the Oil Crisis of October 1973. Over the 1973-78...

This paper presents a simple Cass-Koopmans-Ramsey AK growth model with heterogeneity that explains how policies that increase income inequality may temporarily boost a country’s income growth rate. Briefly put, a change in policy that reduces redistributive transfers will free up...

This paper presents a simple Cass-Koopmans-Ramsey AK growth model with heterogeneity that explains how policies that increase income inequality may temporarily boost a country's income growth rate. Briefly put, a change in policy that reduces redistributive transfers will free up resources to...

We derive necessary and sufficient conditions for the occurrence of ergodic oscillations and geometric sensitivity in a two-sector model of economic growth with labor augmenting externalities. We transform the Euler equation into a first order backward first order equation. Factor intensity...

We study the underlying structure of the two-dimensional dynamical system generated by a class of dynamic optimization models, which allow for intertemporal complementarily between adjacent periods, but which preserve the time additively separable framework of Ramsey models. Specifically, we...
