Using a novel database on countries exposed to coastal risks (CR), this paper estimates an augmented neoclassical growth model that encompasses eight other new growth models. To account for uncertainty related to the number of models and choice of growth determinant proxies, we use a Bayesian...

We investigate how platform market power affects platforms' design choices in ad-funded two-sided markets, where platforms may find it optimal to charge zero price on the consumer side and extract surplus on the advertising side. We consider design choices affecting both sides in opposite ways and...

Voters’ voting decisions crucially depend on their information. Thus, it is an important question how much / what kind of information they should know, as a normative guidance of the optimal extent of transparency. We consider a simple two-alternative majority voting environment, and study the...

The severity of infectious disease outbreaks is governed by patterns of human contact, which vary by geography, social organization, mobility, access to technology and health- care, economic development, and culture. Whereas globalized societies and urban centers exhibit characteristics that can...

We extend nonparametric regression smoothing splines to a context where there is endogeneity and instrumental variables are available. Unlike popular existing es-timators, the resulting estimator is one-step and relies on a unique regularization parameter. We derive uniform rates of the convergence...

This article provides a new explanation for the positive role of cooperatives in quality provision along the agri-food chain. We study the economic rationale for cooperative acting as an intermediary between producers and a downstream (DS) firm when the DS firm cannot observe the individual quality...

We describe the healthcare industry as a mixed oligopoly, where a public and two private providers compete, and examine the effects of a merger between the two private healthcare providers on prices, quality, and welfare. When the price and (eventually) quality of the public provider are regulated...

We study how data portability affects consumer surplus and firms’ profits in a two-period model with a switching cost where two firms compete under a non-negative pricing constraint. The firms can circumvent the constraint by tying another complementary free service (called ”freebies”) with the...

Spatial autoregressive models have been adapted to model data with both a geographic and a compositional nature. Interpretation of parameters in such a model is intricate. Indeed, when the model involves a spatial lag of the dependent variable, this interpretation must focus on the so-called...

Experts and employees in many domains make multiple similar but independent decisions in sequence. Often, the serial position of the case in the sequence influences the decision. Explanations for these serial position effects focus on the role of decision makers’ fatigue, but these effects emerge...
