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.

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...

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 consider a discrete-time two-sector Cobb-Douglas economy with positive sector specific external effects. We show that indetermincay of steady states and cycles can easily arise with constant or decreasing social returns to scale, and very small market imperfections. This is in sharp contrast...

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...

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.

Nous considerons un modele dans lequel l'accumulation de capital huamin depend de deux inputs: l'effort prive d'education des individus et le poids du systeme educatif public represente par son taux d'encadrement. Ce dernier depend notamment du pourcentage d'enseignants qui est choisi par les...

This paper discusses the influence of technological externalities on the dynamic properties of accumulation paths in a two-sector growth model in discrete time.

We build an OLG model with productive capital in which agents live for two periods and display myopia in their altruistic bequest motive. Indeed , they care for their children's welfare like Barro-Becker altruists but what they value is income. A govern,emt redistributes income from the young to...
