Studies of bond return predictability ?nd a puzzling disparity between strong statistical evidence of return predictability and the failure to convert return forecasts into economic gains. We show that resolving this puzzle requires accounting for important features of bond return models such as...

This paper establishes conditions under which the classical CAPM holds in equilibrium. Our derivation uses simple arguments to clarify and extend results available in the literature. We show that if agents are risk averse in the sense of mean-preserving-spread (MPS) the CAPM will necessarily...

We derive a general equilibrium linear relationship between the market prices of risks and market risk aversion under a continuous time stochastic volatility model completed by liquidly traded options. The relation is robust as it is valid for both endowment and production economies, and for...

This paper evaluates the optimal bail-out and bail-in mix in the case of bankruptcy of Banco Espírito Santo (BES), SA, the second largest Portuguese private bank. The solution after the crisis of the BES, was to partition the bank into a good bank (Novo Banco (New Bank)) and keep the toxic...

The Cumulative Prospect Theory (CPT) is one of the most popular theories for evaluating the behavior of decision makers in the context of risk and uncertainty. This theory emerged as a generalization of the Expected Utility Theory (EUT) and being a relatively recent theory, its application has...

Do more active hedge fund managers generate higher returns than their less active peers? We attempt to answer this question. Using Kalman Filter techniques, we estimate the risk exposure dynamics of a large sample of live and dead equity long-short hedge funds. These estimates are then used to...

This paper investigates the implications of time-varying betas in factor models for stock returns. It is shown that a single-factor model (SFMT) with autoregressive betas and homoscedastic errors (SFMT-AR) is capable of reproducing the most important stylized facts of stock returns. An empirical...

This study, based on a search model, attempts to draw out the implications for discussions about reference rates that originated from the recent Libor manipulation scandal, with particular focus on whether the calculation of reference rates should be based solely on actual transaction data and...

Credit ratings have become an indispensable part of the fundamental information infrastructure of credit markets. Credit ratings cover a wide range of issuers including governments, governmental organizations, municipalities, nonfinancial companies and financial institutions, and also cover...

This paper applies a survival analysis to individual hedge fund data reported in the Lipper TASS database. We use several methodologies including the non-parametric survival analysis, the Semi-parametric Cox proportional hazard analysis with shared frailty, and the logit analysis to assess the...
