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.

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...

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...

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...

Using intradistribution dynamics and panel unit root tests, this study considers the economic convergence processes of 53 African countries during the period 1950–2008. The stochastic evidence reveals no global convergence among African countries but provides indications of convergence...

This paper analyzes a model of the transition to agriculture by allowing heterogeneous agents to make the decision on whether to engage in farming or foraging. The threshold level, which divides foragers from farmers, depends on both agricultural productivity and foraging efficiency. As...

The paper studies how market imperfections distort the usual productivity growth using Indian disaggregated level of industrial data for the period of 1998-2005. A modified approach, which has dealt with the imperfections and simultaneity problems of factor choice, accounts for a lower...

We estimate the effect of imports and exports of intermediates on economic growth in a panel of more than 100 among developed and developing economies across the period 1976-2008. We find that both capital and intermediate imports positively affect growth. The overall effect is driven by the...

We introduce demographic shocks in a multi-sector endogenous growth model, a-la Uzawa-Lucas. We show that an analytical solution of the stochastic problem can be found, under the restriction that the capital share equals both the inverse of the intertemporal elasticity of substitution and the...
