Lack of transparency in securitization transactions significantly contributed to the severe financial crisis of 2007–2009. To increase transparency we propose a new mechanism: financial claims with fingerprints. They would allow market participants at each stage of the securitization process...

With adverse selection, diseconomies of scale associated with hierarchies may induce the implementation of a second-best technology. This occurs whenever rents to lower tiers of the hierarchy increase faster than total surplus. This is more likely with longer hierarchies.

In this paper the problem of optimal derivative design, profit maximization and risk minimization under adverse selection when multiple agencies compete for the business of a continuum of heterogenous agents is studied. In contrast with the principal-agent models that are extended within, here...

We consider a full equilibrium model in continuous time comprising a finite number of agents and tradable securities.We show that, if the agents’ endowments are spanned by the securities and if the agents have entropic utilities, an equilibrium exists and the agents’ optimal trading...

We provide results on the existence and uniqueness of equilibrium in dynamically incomplete financial markets in discrete time. Our framework allows for heterogeneous agents, unspanned random endowments and convex trading constraints. In the special case where all agents have preferences of the...

In this paper we deal with the utility maximization problem with a general utility function. We derive a new approach in which we reduce the utility maximization prob- lem with general utility to the study of a fully-coupled Forward-Backward Stochastic Differential Equation (FBSDE).

Supported by several recent investigations, the empirical pricing kernel (EPK) puzzle might be considered a stylized fact. Based on an economic model with state dependent preferences for the financial investors, we want to emphasize a microeconomic view that succeeds in explaining the puzzle. We...

We consider a large trader seeking to liquidate a portfolio using both a transparent trading venue and a dark pool. Our model captures the price impact of trading in transparent traditional venues as well as the execution uncertainty of trading in a dark pool. The unique optimal execution...

We examine the coexistence of banks and financial markets, studying a credit market where the qualities of investment projects are not observable and the investment decisions of entrepreneurs are not contractible. Standard banks can alleviate moral-hazard problems by securing a portion of a...

By any measure, the European Monetary Union and the European Union are in a deep hole. In the summer of 2011 we came uncomfortably close to an uncontrolled sovereign default of an EU country, a member of the European Monetary Union, hardly ten years after the common currency project was...
