We estimate the rate of embodied technological change directly from plant-level manufacturing data on current output and input choices along with histories on their vintages of equipment investment. Our estimates range between 8 and 17 percent for the typical U.S. manufacturing plant during the...

Economic theory indicates that opportunity-cost considerations tend to make schooling countercyclical whereas ability-to-pay considerations have the opposite effect. We examine the college enrollment decisions of individuals using the Current Population Survey and find that their propensity to...

We develop a novel methodology to quantify forecasts based on qualitative survey data. The methodology is generally applicable when quantitative information is available on the realization of the forecasted variable, for example from firm balance sheets. The method can be applied to a wide range...
