The AK growth model is a standard endogenous model. This paper first solves the social planner's problem in this model and shows that the steady state is the only solution to this model. The paper then considers several generalizations of the AK model on the side of technology. Unlike the basic...

This paper presents a simple North-South model of endogenous growth, based on learning by doing, which is consistent with the following empirical observations: (i) the price of investment goods relative to consumption goods has been falling for the last 40 years in most industrialized countries,...

This paper deals with an endogenous growth model with vintage capital and, more precisely, with the AK model proposed in [18]. In endogenous growth models the introduction of vintage capital allows to explain some growth facts but strongly increases the mathematical difficulties. So far, in this...

This paper derives necessary and sufficient conditions under which positional preferences do not induce inter-temporal distortions. When labor supply is exogenous, positional preferences for consumption have been shown to be non-distortionary for a class of models. However, it has not been...

This paper proposes two types of AK-style endogenous growth models to test the physical capital accumulation hypothesis in a ‘typical’ developing country with multiple regimes: a strong version, in which technological progress is fully endogenous to capital accumulation, and a weaker...

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...

Contrary to a popular belief, the most popular Ak growth models display transitional dynamics once the representative agent and complete markets assumptions are overturned. The class of models is identified with diminishing-returns at individual but constant-returns at aggregate due to...

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...
