Econometric land use models study determinants of land-use-shares of different classes: ``agriculture'', ``forest'', ``urban'' and ``other'' for example. Land-use-shares have a compositional nature as well as an important spatial dimension. We compare two compositional regression models with a...

We develop a comprehensive framework for analyzing optimal economic policy during a pandemic crisis in a dynamic economic model that trades off pandemic-induced mortality costs against the adverse economic impact of policy interventions. We use the comparison between the planner problem and the...

We consider quasi likelihood ratio (QLR) tests for restrictions on parameters under potential model misspecification. For convex M-estimation, including quantile regression, we propose a general and simple nonparametric bootstrap procedure that yields asymptotically valid critical values. The...

Policies to incentivize the adoption of renewable energy sources (RES) usually offer little flexibility to adapt to heterogeneous benefits across locations. We evaluate the geographical misallocation of RES associated with the uniform nature of subsidies. We estimate the dispersion of marginal...

Recent years have seen an explosion of interest in the overlap between kin selection and sexual selection, particularly concerning how kin selection can put the brakes on harmful sexual conflict. However, there remains a significant disconnect between theory and empirical research. Whilst empirical...

The paper investigates factors that undermine meritocracy and policies that may restore it. To this purpose, it analyzes the Markovian dynamics, the entrenchment and the welfare properties of an organization whose members’ cooptation decisions are driven by two motives: quality and homophily. It...
The paper studies discriminatory hiring by an organization whose members’ cooptation decisions are driven by two motives: quality and homophily. Small variations in the initial quality or diversity of the organization may lead to virtuous or vicious spirals. In order to avoid depriving itself of...
