A model is developed in which two complementary forms of investment contribute to growth--technology and skill acquisition, and growth takes two forms--TFP and variety growth. The rate of TFP growth depends more heavily on the parameters governing skill accumulation, while variety growth...

The convergence features of an Endogenous Growth model with Physical capital, Human Capital and R&D have been studied. We add an erosion effect (supported by empirical evidence) to this model, and fully characterize its convergence properties. The dynamics is described by a fourth-order system...

How does population aging affect economic growth and factor shares in times of increasingly automatable production processes? The present paper addresses this question in a new macroeconomic model of automation where competitive firms perform tasks to produce output. Tasks require labor and...

This study investigates the effects of lobbying and institutions on the direction of technological change in a two-sector overlapping generations model. Simulation results suggest that in an environment with unbiased institutions producers' rent-seeking activities direct the economy towards a...

This paper analyzes both the growth and the dynamic effects of the subsidy to human capital investment in a two-sector endogenous growth model. We show that the subsidy is growth-increasing, and it determines the dynamic behavior of the physical and human capital variables. Moreover, the economy...

We propose a new microeconomic explanation for the divergent experiences of economies in forming human capital. We suggest that the positive effect of a longer life expectancy on human capital formation arises from two separate effects: a life-expectancy effect and a prolonged intergenerational...

This paper develops a dynamic Heckscher Ohlin Samuelson model with sector-specific human capital and overlapping generations to characterize the dynamics and welfare implications of gradual labor market adjustment to trade. Our model is tractable enough to yield sharp analytic results, that...

This paper sets up an OLG economy with endogenous life expectancy to study how fiscal policy that redistributes between generations can open the door to sunspot equilibria. Agents invest independently in their own human capital, produce and consume output, and receive a pension upon retirement....
