Do futures markets have a stabilizing or destabilizing effect on commodity prices? Empirical evidence is inconclusive. We try to resolve this question by means of a learning-to-forecast experiment in which a futures market and a spot market are coupled. The spot market exhibits negative feedback...

This paper improves continuous-time variance swap approximation formulas to derive exact returns on benchmark VIX option portfolios. The new methodology preserves the variance swap interpretation that decomposes returns into realized variance and option implied-variance.We apply this new...

The overall market for derivative securities is often estimated as more than ten times the World's GDP and many decry the complexity of derivatives as a main contributor to the subprime financial crisis. In this paper, we investigate whether and why complexity is used as a proxy for risk when...

Equity returns are not very predictable despite the presence of many well-documented behavioral biases and risk factors. Why? We collect a comprehensive global dataset covering over 24,000 tradable equities and representing more than 99.9% of the market cap on developed exchanges. Analyzing...

This paper analyzes optimal hedge ratios for foreign exchange (FX) rate risk of companies. Our contribution to the literature is twofold: (i) We present a theoretical two-period regret model that allows us to analyze the determinants of the optimal hedge ratio given the outcome of past hedging...

We argue that perception, priming, and cognition research utilize the tools of stage magic in problematic ways, engaging in what we call "surprise-hacking." Surprise-hacking consists of the pre-experimental planning and staging of counterintuitive and negative results (such as blindness, bias,...

We analyze retail order flow in terms of intra-day feedback trading patterns. Using a unique data set of exchange trades and high-frequency quotes, we first provide evidence that retail investors actively and consciously respond to short-term intra-day returns in a negative feedback, contrarian...

This study attempts to examine the price discovery process and volatility spillovers in Gold futures and spot markets of National Commodity Derivatives Exchange (NCDEX) by employing Johansen’s Vector Error Correction Model (VECM) and the Bivariate ECM-EGARCH(1,1) model. The empirical result...

We will investigate valuation of derivatives with payoff defined as a nonlinear though close to linear function of tradable underlying assets. Derivatives involving Libor or swap rates in arrears, i.e. rates paid in a wrong time, are a typical example. It is generally tempting to replace the...

Volatilities implied from interest rate swaptions are used to assess the size and the sign of the compensation for volatility risk, for dollar, euro and pound rates at a daily frequency, between October 1998 and August 2006. The measurement of the volatility risk premium rests on a simple model...
