Risk minimization for nonsmooth nonconvex problems naturally leads to firstorder sampling or, by an abuse of terminology, to stochastic subgradient descent. We establish the convergence of this method in the path-differentiable case, and describe more precise results under additional geometric...

Backward Induction is a fundamental concept in game theory. As an algorithm, it can only be used to analyze a very narrow class of games, but its logic is also invoked, albeit informally, in several solution concepts for games with imperfect or incomplete informa-tion (Subgame Perfect Equilibrium,...

The Frank-Wolfe algorithm is a popular method for minimizing a smooth convex function f over a compact convex set C. While many convergence results have been derived in terms of function values, hardly nothing is known about the convergence behavior of the sequence of iterates (xt)t2N. Under the...

A reelection-seeking politician makes a policy decision that can reveal her private information on whether her political orientation and capabilities will be a good fit to future circumstances. We study how she may choose inappropriate policies to hide her information, even in the absence of...

In the framework of spatial econometric interaction models for origin-destination flows, we develop an estimation method for the case when the list of origins may be distinct from the list of destinations, and when the origin-destination matrix may be sparse. The proposed model resembles a weighted...

Digital transformation engendered by ICT advances, most notably broadband, pertains to many sectors that are known to drive economic development. This paper seeks to highlight market structure, institutional, and socio-economic factors that influence broadband adoption in Algeria. We apply to a...

We provide new evidence on the causal eect of education on health. Our empirical strategy exploits the reduction in access to college experienced by individuals reaching college age shortly after the 1973 military coup in Chile, which led to a sharp downward kink in enrollment for the aected...

We derive wage equations with individual specic coe¢ cients from a structural model of human capital investments over the life-cycle. This model allows for interruptions in labor market participation, and addresses missing data and attrition issues. We further control for selection in a exible way...

This paper analyzes the determinants of economic growth in coastal economies with the purpose of highlighting the impact of human activity pressure on mangrove blue carbon (BC). We use a Bayesian Model Averaging-based estimation technique to fit alternative growth theories to 1960-2009 data on a BC...

We investigate the impact of professional networks on men's and women's earnings, using a dataset of European and North American executives. The size of an individual's network of influential former colleagues has a large positive association with remuneration, with an elasticity of around 21%....
