The value of the elasticity of substitution between labor and capital (σ) is a “crucial” assumption in understanding the secular decline in the labor share of income and long-run growth. This paper develops and implements a new strategy for estimating this crucial parameter by combining a...

The value of the elasticity of substitution between labor and capital (ó) is a “crucial” assumption in understanding the secular decline in labor share of income (Piketty (2014a), Karabarbounis and Neiman (2014)) and long-run growth (Solow, 1956). This paper begins by examining the role of...

In this paper we present the Ifo Investment Database, which provides annual investment data for 12 investment assets in 50 German industries from 1991 onward. The data is consistent with national accounts statistics provided by the German Federal Statistical Office and is based on investments in...

For the past nearly forty years, China has experienced average annual real GDP growth of close to ten percent, much of it driven by investment and capital accumulation. By 2014, gross capital formation had reached 46 percent of aggregate expenditures. This paper documents the role of investment...

Capital estimates are widely used in economic growth and productivity studies, for profitability considerations and wealth accounting exercises. Yet the calculation of “capital” frequently receives only cursory attention, despite the challenges posed by conceptual difficulties, the...

Recent criticism from different sides has expressed the view that, with scarce resources, there is little justification for massive public funding of higher education. Central to the debate is the conjecture that colleges and universities use their resources inefficiently and focus...

Using a heterogeneous agent model allowing for different degrees of complementarity between capital, skilled and unskilled labour, this paper evaluates supply-side reforms consistent with lower public debt-to-GDP in the long-run. We find that, relative to the other tax reforms, capital tax cuts...

Casual empiricism suggests that “unwarranted” wage changes, defined as the part of wage growth that is not explained by changes in labour productivity, are negatively associated with the return on capital. The main point of this paper is to show that “unwarranted” wage changes have no...

We study the interplay of inequality and trust in a dynamic game, in which trust increases efficiency and thus allows higher growth of the experimental economy in the future. We find that trust is initially high in a treatment starting with equal endowments, but decreases over time. In a...
