This paper presents a tractable endogenous two-sector growth model with non-Gorman intra-temporal preferences and directed technical change. One of the two consumption goods is a necessity, whereas the other is a luxury. If the economy starts with a low initial knowledge stock, households are...

In the course of growth, sectoral data features (i) changing relative expenditures of different sectors, (ii) non-constancy in the growth rates of relative prices and (iii) shifting relative TFP growth rates of sectors. This paper presents a simple model of directed technical change, which is...

This paper demonstrates that the role of the personal income distribution for an economy's process of development through risky human capital accumulation critically depends on the shape of the saving function. Empirical evidence for the U.S. strongly suggests that the marginal propensity to...

The optimal mix of growth policies is determined within a comprehensive endogenous growth model. The analysis captures important elements of the tax-transfer system and accounts for transitional dynamics. Currently, for calculating corporate taxable income US firms are allowed to deduct...

Market imperfections may lead to underinvestment in dynamic general equilibrium models. An interesting but unexplored question is whether policy interventions which attenuate underinvestment gaps necessarily imply that consumption will initially decline. By employing a calibrated version of a...

This paper develops a two-sector R&D-based growth model with congestion effects from increasing urban population density. We show that endogenous technological progress causes structural change if there are positive productivity spillovers from the modern to the traditional sector and Engel’s...
