In this paper we examine the competitive equilibria of a dynamic stochastic economy with complete markets and collateral constraints. We show that, provided both the set of asset payoffs and collateral levels are sufficiently rich, the equilibrium allocations with sequential trades and...

We study a model of occupational choice where workers must rely on their social contacts to acquire job vacancy information. Contrary to the existing literature, we allow for worker heterogeneity in terms of their idiosyncratic skill-types. In this case, the allocation of talent (the matching of...

We introduce the Realized Exponential GARCH model that can utilize multiple realized volatility measures for the modeling of a return series. The model specifies the dynamic properties of both returns and realized measures, and is characterized by a flexible modeling of the dependence between...

The aim of this paper is to investigate how the capacity of an economic system to absorb shocks depends on the specific pattern of interconnections established among financial firms. The key trade-off at work is between the risk-sharing gains enjoyed by firms when they become more interconnected...

We establish the equivalence between a commonly used out-of-sample test of equal predictive accuracy and the difference between two Wald statistics. This equivalence greatly simplifies the computational burden of calculating recursive out-of-sample tests and evaluating their critical values. Our...

We introduce a multivariate GARCH model that incorporates realized measures of volatility and covolatility. The realized measures extract information about the current level of volatility and covolatility from high-frequency data, which is particularly useful for the modeling of return...

In this paper we study how access to bank lending during the recent financial crisis differed between family and non-family firms. Our theoretical prediction is that the presence of a family block-holder in the company attenuated the agency conflict in the borrower-lender relation, because of...

In the context of an emission trading scheme (ETS), we study how uncertainty over the environmental policy affectsfirms' investment in low-carbon technologies. We develop a three period sequential model that combines the industry and the electricity sectors and encompasses both irreversible and...

The development of models for variables sampled at different frequencies has attracted substantial interest in the recent econometric literature. In this paper we provide an overview of the most common techniques, including bridge equations, MIxed DAta Sampling (MIDAS) models, mixed frequency...

We propose a stylised dynamic model to understand the role of social networks in the phenomenon we call "globalization." This term refers to the process by which even agents who are geographically far apart come to interact, thus being able to overcome what would otherwise be a fast saturation...
