While the existence of fixed costs in entering asset markets is the leading rationalization of the "participation puzzle" -the fact that most households do not hold stocks, despite the diversification gains and the significant risk-premium involved-, most motivations of these fixed costs are as...

We propose a new model for the variance between multiple time series, the Regime Switching Dynamic Correlation. We decompose the covariances into correlations and standard deviations and the correlation matrix follow a regime switching model; it is constant within a regime but different across...

This paper develops a theory of strategic trading in markets with large influential arbitrageurs. If arbitrageurs are not very well-capitalized, margin requirements or capital constraints make their trades predictable. Other market participants can exploit this by trading against them....

Traders with short horizons and privately known trading limits interact in a market for a risky asset. Risk-averse, long horizon traders supply a downward sloping residual demand curve that face the short-horizon traders. When the price falls close to the trading limits of the short horizon...

Using more than two years of daily interest rate cap price data, this paper provides a systematic documentation of a volatility smile in cap prices. We find that Black (1976) implied volatilities exhibit an asymmetric smile (sometimes called a sneer) with a stronger skew for in-the-money caps...

Conventional time series analysis, focusing exclusively on a time series at a given scale, lacks the ability to explain the nature of the data generating process. A process equation that successfully explains daily price changes, for example, is unable to characterize the nature of hourly price...

This paper introduces a tractable, structural model of subjective beliefs. Since agents that plan for the future care about expected future utility flows, current felicity can be increased by believing that better outcomes are more likely. On the other hand, expectations that are biased towards...

This paper studies predatory trading: trading that induces and/or exploits other investors' need to reduce their positions. We show that if one trader needs to sell, others also sell and subsequently buy back the asset. This leads to price overshooting, and a reduced liquidation value for the...

Based on Bergara and Licandro´s Model (2001), this paper studies the relationship between the requirements of prudential regulations for risks management and its effects on the loans portfolio. The financial regulation (Basle´s Accords, I and II) becomes sensible to risks (using Value at...
