This paper explores some implications for valuation and investment of challenging the standard assumption that there are no aggregate pure profits in the US economy. First, it highlights the theoretical importance of monopoly rents for fluctuations in average Q. A series for such rents is then...

This paper formulates and compares various specifications of investment adjustment costs in a simple dynamic general-equilibrium model and studies their implications by showing some analytic results. One way to introduce costs is to incorporate them as a constant elasticity of substitution...

This paper applies some lessons from recent estimation of investment models with firm-level data to the aggregate data with an eye to rehabilitating convex costs of adjusting the capital stock. In recent firm-level work, the response of investment to output and other "fundamental" variables is...

This paper measures the impact of crime on firm investment by exploiting variation in kidnappings in Colombia from 1996 to 2002. Our central result is that firms invest less when kidnappings directly target firms. We also find that broader forms of crime--homicides, guerrilla attacks, and...

Taking the mean-variance portfolio model as a benchmark, we compute the optimally diversified portfolio for banks located in France, Germany, the U.K., and the U.S. under different assumptions about currency hedging. We compare these optimal portfolios to the actual cross-border assets of banks...

We use earnings forecasts from securities analysts to construct more accurate measures of the fundamentals that affect the expected returns to investment. We find that investment responds significantly -- in both economic and statistical terms -- to our new measures of fundamentals. Our...

This paper uses the response of investment to identified structural shocks to investigate some key issues, including the nature of adjustment costs and investment's responsiveness to user cost. In the estimation, the model parameters are chosen to match as closely as possible the impulse...

In the United States, the percentage standard deviation of residential investment is more than twice that of non-residential investment. In addition, GDP, consumption, and both types of investment co-move positively. We reproduce these facts in a calibrated multi-sector growth model where...

By extrapolating Gordon's (1990) measures of the quality-bias in the official price indexes, we construct quality-adjusted price indexes for 24 types of equipment and software (E&S) from 1947 to 2000 and use them to measure technical change at the aggregate and at the industry level....
