In his seminal article, Samuelson (1965) proposes the maturity effect that volatility of futures prices should increase as futures contract approaches expiration. This study provides new evidence on the maturity effect by examining a more extensive set of futures contracts over longer period...

Fine wine has become an attractive alternative asset class in recent decades. In our study, we take the market microstructural perspective and verify how innovations in trading infrastructure affect the fine wine market. More specifically, we examine the average prices and the return volatility...

In a seminal article, Samuelson (1965) [Samuelson, P. A. (1965), “Proof that properly anticipated prices fluctuate randomly,” Industrial Management Review 6, 41–49.] proposes the maturity effect that the volatility of futures prices should increase as futures contract approaches maturity....

We consider demand function competition with a finite number of agents and private information. We show that any degree of market power can arise in the unique equilibrium under an information structure that is arbitrarily close to complete information. In particular, regardless of the number...

The paper proposes a new robust estimator for GARCH-type models: the nonlinear iterative least squares (NL-ILS). This estimator is especially useful on specifications where errors have some degree of dependence over time (weak-GARCH) or when the conditional variance is misspecified. I illustrate...

I employ a parsimonious model with learning but without conditioning information to extract time-varying measures of market-risk sensitivities, pricing errors and pricing uncertainty. Parameters estimated for U.S. equity portfolios show significant fluctuations, along patterns that change across...

This study illuminates the difference in the intraday return-volume relationships of spot and index futures. The quantile regression analyses show that the widening effect of the spot trading volume on the distribution of spot returns disappears within a short period of time, whereas that of the...

This paper examines the idiosyncratic volatility (IV) puzzle in the Indian stock market for the period 1999–2014. Univariate and bivariate sorting, as well as cross-section regressions, suggest a positive relation between idiosyncratic volatility and future stock returns. However, this...
