We derive the aggregate normalized CES production function from idea-based microfoundations where firms are allowed to choose their capital- and labor-augmenting technology optimally from a menu of available technologies. This menu is in turn augmented through factor-specific R&D. The considered...

Housing prices diverge from construction prices after 1997 in four major countries. Besides, TFP differences between construction and the general economy account for the evolution of construction prices in the U.S. and Germany, but not in the U.K. and Spain.

We may be on the cusp of a 'second industrial revolution' based on advances in artificialintelligence and robotics. We analyze the implications for inequality and output, usinga model with two assumptions: 'robot' capital is distinct from traditional capital in itsdegree of substitutability with...

This study quantifies the effect of aging on the age-wage profile, using data from Japan, which is the fastest aging country in the world. Using a model with imperfect substitution among labor inputs in different age groups, we obtain two findings. First, the change in age composition of male...

Existing studies on the downward trend in the labor share of income mostly focus on changeswithin individual countries. I document, however, that half of the global decline in the laborshare of income can be traced to the relocation of activities between countries. I develop atwo-country model...

In general, empirical studies on economics rely on the assumption of constant capital share of income both at the aggregate level and at the sector level. However, there is no empirical evidence supporting the constancy of capital share at the sector level. In this paper, using Colombian data,...

Profitability in the United States has been rising since the early 1980s and by 1997 was at its highest level since its postwar peak in the mid 1960s, and the profit share, by one definition, was at its highest point. In this paper I examine the role of the change in the profit share and capital...
