We investigate whether social connections within the hedge fund industry affect investment decisions. Data is collected from interviews and observations with industry participants in Europe, the United States and Asia. Quantitatively analyzing the mapped social network, we find that decision...

Almost all relevant literature has characterized implied volatility as a biased predictor of realized volatility. This paper provides new time series techniques to assess the validity of this finding within a foreign exchange market context. We begin with the empirical observation that the...

The persistence of the forward premium has been cited both as evidence of the failure of the unbiasedness hypothesis and as rationale for the forward premium anomaly. Exploring the nature of this may provide useful insights into issues of market efficiency. This paper examines the proposition...

This paper evaluates the ability of dividend ratios to predict the equity premium. We conduct an out-of-sample comparative study and apply the Goyal and Welch (2003) methodology to equity premia derived from the UK FTSE All-Share and the Samp;P 500 indices. Preliminary in-sample univariate...

Harvey, Kellard, Madsen and Wohar (2010, Review of Economics and Statistics, 92, 367-377) contains data construction errors and the reported results are incorrect. This erratum provides the corrected results

The dynamic conditional correlation (DCC) and co-range models are two main frameworks widely used to employ range-based univariate volatility. Using the two approaches, we build novel multivariate range-based EGARCH (REGARCH) models: a DCC-REGARCH and co-range REGARCH (CRREGARCH) model, as well...

The role of oil price shocks in economic activity and inflation is controversial but a key input to economic policy. To clarify these relations, we employ a refined measure of oil shocks based on decomposing realized volatility and estimated using intraday oil futures data. In reconciling prior...

The sheer scale of contemporary environmental and associated grand societal challenges underscores the necessity for the successful generation and application of innovations that make for greater environmental sustainability. Relatedly, there has been growing interest in how national...

The purpose of this paper is to evaluate the ability of dividend ratios to predict the UK equity premium. Specifically, we apply the Goyal and Welch (2003) methodology to equity premia derived from the UK FTSE All-Share index. This approach provides a powerful graphical diagnostic for predictive...
