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...

The labor share in Japan has been declining significantly over the last three decades, accompanied by persistent stagnation and an unprecedented increase in economic inequalities. Since these dynamics are likely to be interrelated, understanding the drivers of the labor share might contribute...

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...

Despite a growing literature on population aging, empirical studies exploring mechanisms between aging and income inequality are scarce. This paper estimates the impact of aging on inequality via the perspective of labor income share, based on cross-country information covering the period...

Contradicting the conventional wisdom of constant factor shares, the portion of national income accruing to labor has been trending downward in the last three decades. This decline must have contributed to rising inequality as labor income is more evenly distributed than capital income. This...

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 objective of this paper is to study how manufacturing plants in India adjusted to trade liberalization during the period 1998-99 to 2007-08. We estimate how the labor share changed due to tariff reduction. Our results indicate that a decline in output tariffs led to an increase in the labor...

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...

This paper provides novel empirical evidence on the role of trade and structural transformation as potential drivers of the labor income share. Using cross-country data, both at the national and sectoral level, we find that trade openness is negatively correlated with the labor income share. The...

Labor income shares have been falling in many advanced and emerging economies within the last few decades, partly as a result of a combination of impacts from technology and increased global integration. This in turn is associated with the relatively slow growth of wages, especially for...
