Abstract

Previous studies have emphasized that Roeger's methodology generates too high markups. This feature is confirmed on the basis of the unrealistically low capital shares implied by the estimates herein. Theoretically, it is shown that the normalization choice, the slow adjustment of capital and the mismeasurement of capital expenditures, each produces an upward bias. For instance, the price-based estimated markup is in fact the markup adjusted for returns to scale on the variable inputs only. Based on the empirical analysis, each of these sources of overestimation is very likely to play a role.
