We consider models for network-indexed multivariate data, also known as graph signals, involving a dependence between variables as well as across graph nodes. The dependence across nodes is typically established through the entries of the Laplacian matrix by imposing a distribution that relates the...

This article considers linear panel data models where the dependence of the regressors and the unobservables is modeled through a factor structure. The number of time periods and the sample size both go to infinity. Unlike in most existing methods for the estimation of this type of models,...

Nonparametric inference on tail conditional quantiles and their least squares analogs, expectiles, remains limited to i.i.d. data. Expectiles are themselves quan- tiles of a transformation of the underlying distribution. We develop a fully operational kernel-based inferential theory for extreme...

We present a new algorithm to solve min-max or min-min problems out of the convex world. We use rigidity assumptions, ubiquitous in learning, making our method – the backtrack Hölder algorithm applicable to many optimization problems. Our approach takes advantage of hidden regularity properties and...

We study the design of environmental policy in the e-commerce sector and examine two main questions. First, what is the appropriate “level” of intervention along the value chain. Second, which instruments should be used at a specific level in the vertical chain? We consider a model with two...

Did migrants make Paris a mecca for the arts and Vienna a beacon of classical music? Or was their rise a pure consequence of local actors? We use data on more than 22,000 historical individuals born between the years 1000 and 2000 to estimate the contribution of famous immigrants, emigrants and...

Industries with more complex input-output relationships are comparatively larger in U.S. states with higher levels of trust. This specialization pattern is not driven by differences in the states' and industries' other observable characteristics. Given the importance of complexity in economic...

To assess the impact of taxation on the consumption of sugar-sweetened beverages (SSBs) most economic studies using household data consider the average consumer. Individual consumption is, however, very heterogeneous. In this paper, we propose a three-step methodology to evaluate the impact of SSB...
