This paper develops a macroeconomic model with a banking sector in which banks face endogenous borrowing constraints. There is no uncertainty about economic fundamentals. Banking bubbles can emerge through a positive feedback loop mechanism. Changes in household confidence can cause the collapse...

We use recent methods for the analysis of time series data, in particular related to breaks in trends, to establish that human factors are the main contributors to the secular movements in observed global and hemispheric temperatures series. The most important feature documented is a marked...

We analyze a labor market with search and matching frictions where wage setting is controlled by a monopoly union. We take a benevolent view of the union in assuming it to care equally about employed and unemployed workers and we assume, moreover, that it is fully rational, thus taking job...

We study a new data set of US sports card conventions in order to evaluate the pricing theory of two-sided markets. Conventions are two-sided because organizers must set fees to attract both consumers and dealers. We have detailed information on consumer price, dealer price and, since most...

Climate change detection and attribution have been the subject of intense research and debate over at least four decades. However, direct attribution of climate change to anthropogenic activities using observed climate and forcing variables through statistical methods has remained elusive,...

We generalize de Finetti’s exchangeable Bayesian model to accommodate ambiguity. As a central motivating example, we consider a policy maker facing a cross-section of markets in which …rms play an entry game. Her theory is Nash equilibrium and it is incomplete because there are multiple...

Though risk aversion and the elasticity of intertemporal substitution have been the subjects of careful scrutiny when calibrating preferences, the long-run risks literature as well as the broader literature using recursive utility to address asset pricing puzzles have ignored the full...
