There are many business situations in which investments by a supplier and a producer (“coinvest-ments") are both necessary for either of them to grasp a business opportunity. For instance, better quality tanks are needed to manufacture reliable hydrogen-powered vehicles. One of these two firms,...

We set up a formal framework to characterize encompassing of nonparametric models through the distance. We contrast it to previous literature on the comparison of nonparametric regression models. We then develop testing procedures for the encompassing hypothesis that are fully nonparametric. Our...

We study a two-period industry where firms are run by agents privately informed about their (persistent) costs, and principals can only use spot contracts. We characterize novel semi-separating equilibria where principals randomize in one or both periods. These equilibria have the following...

This paper analyzes the determinants of economic growth in coastal countries and discusses their potential consequences on mangrove blue carbon (BC). We use a Bayesian averaging of classical estimates technique to fit models reflecting alternative theories to 1960–2009 data on 23 specific coastal...

Dyadic isolation is the tendency of some individuals to be involved in pairwise interactions rather than in larger group interactions. This article investigates the interpersonal processes associated with the dyadic isolation of individuals with depressive symptoms. We hypothesize that such...

In an investment experiment, we show variations in information affect belief and decision behaviors within the information-beliefs-decisions chain. Subjects observe the time series of a risky asset and a signal that, in random rounds, helps predict returns. When they perceive the signal as useless...

We develop a bilateral oligopoly framework with manufacturer-retailer bargaining to analyze the impact of retail mergers on market outcomes. We show that the surplus division between manufacturers and retailers depends on three bargaining forces and can be interpreted in terms of an “equilibrium of...

Face aux enjeux de compétitivité, de formation des prix et de répartition de la valeur, la contractualisation suscite des débats récurrents. Cet ouvrage propose une analyse approfondie des usages et impacts des contrats dans la construction des échanges de biens agricoles, forestiers et...

The aim of this paper is to link the machine learning method of multilayer perceptron (MLP) neural network with the classical analysis of stochastic state space models. We consider a special class of state space models with multiple layers based on affine conditional Laplace transforms. This new...

We develop a dynamic model of energy use that relies on three primary sources: a ‘dirty’ fossil resource, a ‘clean’ fossil resource equipped with a specific abatement device, and a carbon-free renewable energy source. The total amount of carbon emissions is limited by a given carbon budget....
