Economic complexity methods have become popular tools in economic development, economic geography, and innovation. Yet, despite their widespread adoption, we lack a mechanistic model that provides these methods with a solid mathematical foundation. Here, we analytically derive the economic...

This article introduces the Jean Nicolas Database, a comprehensive resource doc-umenting 8,516 rebellions in France between 1661 and 1789. Based on a survey con-ducted by Jean Nicolas from the early 1980s to the late 1990s, the database records each event’s typology, chronology, location,...

Inequality in outcomes may emerge through a reinforcement process in which stochastic variation in values is determined by prior values but may also originate in preexisting differences in unobserved factors. A common approach toward differentiating between these origins in longitudinal data is to...

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...

Firms receiving independent signals on a common-value risky project compete to be the first to invest. When firms are symmetric and competition is winner-take-all, rents are fully dissipated in equilibrium and the extent to which signals are publicly disclosed is irrelevant for welfare. When...
