Dramatic declines in capital tax rates among U.S. states and European countries have been linked by many commentators to tax competition and an inevitable race to the bottom. This paper provides an empirical analysis of the reaction of capital tax policy in a given U.S. state to changes in...

The value of the elasticity of substitution between labor and capital (σ) is a crucial assumption in the study of factor incomes (e.g., Piketty (2014a), Piketty and Zucman (forthcoming), Karabarbounis and Neiman (2014)) and long-run growth (Solow, 1956). This paper begins by examining the role...

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...

Nearly 75 years ago, John Hicks introduced and formalized the concept of the elasticity of substitution between capital and labour and its relation to derived demand. The resulting formula has proven very useful in understanding the derived demand for productive factors, the distribution of...

What role does noise play in equity markets? Answering this question usually leads immediately to specifying a model of fundamentals and hence the pervasive joint hypothesis quagmire. We avoid this dilemma by measuring noise volatility directly by focusing on the behavior of country closed-end...

Though the U.S. federal investment tax credit (ITC) was permanently repealed in 1986, statelevel ITCs have proliferated over the last few decades.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...

Is real investment fully determined by fundamentals or is it sometimes affected by stock market misvaluation? We introduce three new tests that: measure the reaction of investment to sales shocks for firms that may be overvalued; use Fama-MacBeth regressions to determine whether overinvestment...

This note uses insights from cointegration analysis to reexamine two separate but related issues concerning the estimation of production function parameters. Fisher (1971) documented a paradox in estimating substitution elasticities

When investment is irreversible, theory suggests that firms will be "reluctant to invest." This reluctance creates a wedge between the discount rate guiding investment decisions and the standard Jorgensonian user cost (adjusted for risk). We use the intertemporal tradeoff between the benefits...

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...
