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...

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...

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...

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...

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...

The literature on short-term rental emphasises the heterogeneity of the hosts population. Some argue that professional and opportunistic hosts differ in terms of their pricing strategy. This study highlights how differences in market perception and information create a price differential between...

This study re-examines the relationship between women on corporate boards (WOCB) and corporate social performance (CSP) for a sample of companies from the Fortune 1000 ranking over the period 2004 to 2018 (ranked from 501 to 1000). To take into account the complex and non-linear relationship as...

Developing a database that includes 59 countries, our study sheds light on the role of mobile telecommunications markets' concentration on countries' competitiveness. Performing several estimations and using an instrumental variable that aims to explain the degree of concentration in mobile phone...

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...
