We study how financial market efficiency affects a measure of diversification of output across industrial sectors borrowed from the portfolio allocation literature. Using data on sector-level value added for a wide cross section of countries and for various levels of disaggregation, we construct...

This paper reviews and appraises the body of empirical research on the association between .nancial markets and economic growth that has accumulated over the past quarter-century. The bulk of the historical evidence suggests that financial development a¤ects economic growth in a positive,...

Between 2000 and 2007, the gender gap in earnings in the US real estate sector increased, especially in local markets where house prices appreciated relatively more. Firm frictions and the presence of small children in the household do not explain the widening of the gender gap, while sorting on...

A decision maker tests whether the gradient of the loss function evaluated at a judgmental decision is zero. If the test does not reject, the action is the judgmental decision. If the test rejects, the action sets the gradient equal to the boundary of the rejection region. This statistical...

A statistical decision rule incorporating judgment does not perform worse than a judgmental decision with a given probability. Under model misspecification, this probability is unknown. The best model is the least misspecified, as it is the one whose probability of underperforming the judgmental...

Bayesian decisions are observationally identical to decisions with judgment. Decisions with judgment test whether a judgmental decision is optimal and, in case of rejection, move to the closest boundary of the confidence interval, for a given confidence level. The resulting decisions condition...
