Using a simple overlapping generations model, this note shows that an improvement in the efficiency of human capital investment decreases the net income of the young household while increasing that of the old. Without compensating redistribution, it deteriorates lifetime utilities of all...

We present results from quantitative exercises using the Lucas and Romer endogenous growth models, from which we calculate welfare losses from the distortions presented in the Romer model. Moreover, comparing the models to data, we show that an economy governed by the Romer model would attain a...

Using a panel dataset of 86 countries from 1960-2005, this paper empirically assesses the effect of several democracy proxies (by means of the Polity IV database), together with a set of control variables, such as human capital and the initial level of GDP per capita, on the rate of economic...

This paper study the relationships between tourism and economic growth by introducing a dynamic model whose ingredients are an economy producing a non-traded consumption good consumed by domestic residents and foreign tourists and a capital good. The model analyses the relationships between...

Capital (physical and human) doesn't flow from rich to poor countries. We show that in order to solve these twin paradoxes, assumption of externality of physical capital is better than assumption of externality of human capital.

This paper investigates the effects of wealth-enhanced social status using an optimizing monetary growth model with non-separable utility function between consumption and wealth. Within this framework, we first arrive a conclusion that, in the case of no wealth effects, an increase in the rate...

This note examines the effect of per-period communication costs in a model of expanding product variety. It is shown that while a decrease in communication costs leads to growth in aggregate output, this growth is only transitional with the growth rate falling to zero in the long run as the...

This paper shows that the Saito version of Solow growth model contains an error. It corrects this error. It further applies some built-in functions of Mathematica to the correct version of Solow economic growth model and derives some interesting graphs from the Solow convergent paths.

The paper develops a simple Solow-like growth model, with two independent geographical spaces, where migration is possible and it is stimulated by wage differences. The model assumes a congestion externality: high concentration of individual agents in one of the economic spaces implies losses in...

We empirically analyse the impact of trade on income levels in sub-Saharan African countries. The results indicate that the linkage between these two variables is negative for these countries. This outcome may explain the negative sign of the Africa dummy in income (or growth) regressions.
