This paper studies investor's attention to gold price movements by analyzing the relationship between gold price changes and internet search queries for gold. We find a positive relationship of gold price volatility and search queries and a strong asymmetric effect of negative gold price changes...

We use quantile regressions to demonstrate that volatility persistence and the asymmetric "leverage" effect are high volatility phenomena. More specifically, we find that (i) low volatility is not persistent, but high volatility all the more, even featuring properties of explosive processes;...

Dyhrberg (2016) analyzes the relationship between Bitcoin, gold and the US dollar within a GARCH framework and states that Bitcoin can be classified as something in between gold and the US dollar. This paper uses the same sample and econometric models to replicate the findings and demonstrates...

We propose to estimate the variance of a time series of financial returns through a quantile autoregressive model (QAR) and demonstrate that the return QAR model contains all information that is commonly captured in two separate equations for the mean and variance of a GARCH-type model. In...

In December 2017, both the CBOE and the CME introduced futures contracts on bitcoin. We investigate to what extent they provide useful information for the price discovery of bitcoin. We rely on the information share methodology of Hasbrouck (1995) and Gonzalo and Granger (1995) and find that the...

Insider trading laws are designed to ensure a level-playing field and trust in financial markets at the expense of less efficient markets. This paper argues that insider trading laws fail to ensure a level-playing field and instead facilitate fraud and undermine trust and fairness. We use a...

There is a well documented asymmetric return - volatility effect of equity returns, that is, negative shocks increase volatility by more than positive shocks. This paper analyzes the return - volatility relationship of commodity price changes and finds an inverted asymmetric effect with a...

This paper proposes a new approach to identify safe haven assets and to characterize their relationship with the market. We use quantile regression to analyze the returns of potential safe haven assets conditional on all market conditions including periods of financial turmoil. We find a...

This paper analyses the impact of the June 23, 2016 Brexit vote on the British and Australian currency and equity markets. The two markets are particularly interesting as they were both strongly impacted by the Brexit vote, have cross-listed stocks and non-overlapping trading hours. Whilst the...

The aim of this study is to provide a comprehensive description of the dependence pattern of stock returns by studying a range of quantiles of the conditional return distribution using quantile autoregression. This enables us in particular to study the behavior of extreme quantiles associated...
