Social contacts help workers to find jobs, but those jobs need not be in the occupations where workers are most productive. Hence social contacts can generate mismatch between a worker's occupational choice and his comparative productive advantage. Thus economies with dense social networks can...

We develop an infinite horizon equilibrium model in which banks finance long term assets with non-tradable debt. Banks choose the amount of debt and its maturity taking into account investors’ preference for short maturities (which better accommodate their preference shocks) and the risk of...

We develop and calibrate a dynamic equilibrium model of relationship lending in which banks are unable to access the equity markets every period and the business cycle is a Markov process that determines loans’ probabilities of default. Banks anticipate that shocks to their earnings and the...

We analyze the cyclical effects of moving from risk-insensitive (Basel I) to risk-sensitive (Basel II) capital requirements in the context of a dynamic equilibrium model of relationship lending in which banks are unable to access the equity markets every period. Banks anticipate that shocks to...

This paper develops a tractable general equilibrium model in which money markets provide structural funding to some banks. When bank default risk becomes significant, retail deposit insurance creates an asymmetry between banks that operate in savingsrich regions, which can remain financed at...

We assess the effects of imitation and intellectual property (IP) protection in a model of industry dynamics in which the value of IP is eroded by further innovations and imitations. Innovations result from the development of ideas engendered by entrepreneurs. We find that innovation and welfare...

This paper reviews the background and key policy challenges of the current situation of the Spanish economy. It describes the strengths and weaknesses of Spain's recent long growth cycle, the real and financial imbalances accumulated towards its end, and the troubles faced at the current stage....

The protection that innovators obtain through intellectual property rights crucially depends on their incentives and ability to litigate infringers. Taking patents as a notable example, we study how the financing of legal costs can alter the incentives to litigate in defense of a petent and,...

Firms that are more highly levered are forced to raise capital more often, a process that leads to the generation of information. Of course transparency can improve the allocation of capital. However, when the information about the firm affects the terms under which the firm transacts with its...

This paper examines the experience of fourteen developed countries for which there are about thirty years of quarterly inflation-adjusted housing price data. Price dynamics is modelled as a combination of a country-specific component and a cyclical component is a two-state variable captures...
