The relationship between a declining labor income share and a falling relative price of capital requires capital and labor to be gross substitutes at the aggregate level (i.e., σ-Agg1). We argue that this restriction can be relaxed if we distinguish labor by skills and identify differential...

The constancy of the elasticity of factor substitution (σ) makes its role as a driver of the labor income share exogenous. The constant elasticity of substitution (CES) (Arrow et al., 1961) production function has predominantly been used to support this causal relationship. This paper argues...

Globally, the share of income going to labor (the “labor income share”) is declining. However, this aggregate decline hides more than it reveals. While the labor income share has decreased for low-skilled workers, this has been concurrent with an increase for high-skilled workers....

The accumulation principle suggests that complementarity between capital and labor forces the labor income share to rise in the presence of capital accumulation. The CES model estimates using data from 20 Japanese industries between 1970 and 2012 explain the same outcome but with substitutable...

In this paper we build a theoretical model on the wage effect of skilled emigration to the fluctuations in real exchange rate through the relative prices of nontradables. Our theoretical model predicts that skilled emigration is associated with an increase in the prices of nontradable, which in...

Thousands of Moldovans emigrated for work abroad over the last few years following nearly a decade of economic stagnation in their home country. At about 30 percent of the labor force, Moldova's emigrant population is in relative terms among the largest in the world. This study uses a unique...

Despite its long pedigree, studies on the role of the substitution elasticity between capital and labor mostly assume a homogeneous labor market. This paper extends this literature by considering a heterogeneous labor market with capital-skill complementarity. Technological advancement, global...

Despite steady growth of the literature on labor income share, empirical studies are mostly limited to country-level analyses. At the sectoral level, data on labor income share are available only for advanced countries. This paper overcomes this constraint and provides some preliminary outcomes...
