Research on the elasticity of substitution between capital and labor - σ - has been proceeding for 75 years. While there is clearly a strong case for the importance of σ in the analysis of growth and other economic issues, much less agreement exists on the value of σ. This paper offers some...

This study provides some perspective on analyzing the effects of corporate taxation on capital formation. Our framework translates tax policy legislation into real outcomes, and identifies three parameters that play a central role in determining the impact on policy. The remainder of the paper...

The elasticity of substitution between capital and labor features prominently in several areas of economic research. However, a consensus estimate remains elusive. We develop an estimation strategy that filters panel data in an original way and avoids several pitfalls - difficult-to-specify...

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...

Though the U.S. federal investment tax credit (ITC) was permanently repealed in 1986, state-level ITCs have proliferated over the last few decades. Are these tax incentives effective in increasing investment within the state? How much of this increase is due to investment drawn away from other...

Bank intermediated finance has been cited frequently as the preferred means for channeling funds from savers to firms. Germany is the prototypical economy where universal banks allegedly exert substantial influence over firms. Despite frequent assertions about the considerable power of German...

Large and sustained differences in marginal products of capital (MPKs) across countries are sharply at odds with the core implications of the neoclassical framework. Lucas (1990) and many subsequent studies have examined reasons for this MPK differential. In a recent contribution, Caselli and...

Market power exercised by firms has become central to macroeconomics. Recent theoretical work highlights the importance of the relation between market power and inflation. We examine this relation for individual firms in eleven U.S. industries. Our econometric framework exploits restrictions...

By studying the gap between the discount rates used by executives and shareholders, we assess the extent to which governance problems distort firm behavior. The estimation strategy recovers discount rates used by executives from the pattern of their actual investment spending. Our empirical work...

The transmission channels through which monetary policy affects business investment remain opaque. This paper examines the importance of the interest rate and credit channels on business fixed investment in Germany. We have at our disposal three uniquely rich datasets -- a panel of financial...
