A prototypical vintage capital model of economic growth is developed, where the decision to replace old technologies with new ones is modeled explicitly. Technological change is investment specific. Depreciation in this environment is an economic , not a physical concept.

The costs of import substitution (IS) as a strategy for industrialization, which was deemed synonymous with economic development by many development economists of the fifties and sixties, were shown to be substantial in the influential and nuanced studies of the seventies and eighties under the...

This paper explores the effect of policy variability (or frequency of regime switching) on economic growth and welfare. We study a one sector growth model where investment can be subsidized at either a positive rate or not subsidized at all.

The role that investment-specific technological change played in generating postwar US growth is investigated here. The premise is that the introduction of new, more efficient capital goods is an important source of productivity change, and an attempt is made to disentangle its effects from the...

We present a general equilibrium model with oligopsonistic market structure in one of the sectors. Buyers of inputs can set the price of inputs by being involved in rent seeking activities. The framework developed is applied to the Bulgarian economy in particular to the agro-food chain.

L'analyse des effets de la privatisation porte généralement sur des aspects microéconomiques. Néanmoins, lorsque la privatisation est massive, l'évaluation de l'impact macroéconomique présente un grand intérêt. Dans un environnment de crise économique chronique, la privatisation peut...

We consider an overlapping generations model with endogenous labor supply. Individuals live for two periods and have different skills. We state equivalence properties of different transfer policies, assuming the government cannot identify individuals and has a limited range of instruments that...

This paper preserves many of the primary features of the standard neoclassical framework while introducing some modifications that transform it into an open economy endogenous growth model with knowledge accumulation. The accumulation of knowledge is determined in part by the extent of knowledge...

The endogenous growth models of Lucas (1988) and Uzawa (1965) that rely on a formal training technology to generate growth, and the endogenous technologiacl change model of Romer (1990) fit the long-run secular growth path of the US economy equally well. However, the Romer model yields...
