This paper investigates the liquidity effect in asset pricing by studying the liquiditypremium relationship of an American Depositary Receipt (ADR) and its underlying share. Using the Amihud (2002) measure, the turnover ratio and trading infrequency as proxies for liquidity, we show that a higher ADR premium is associated with higher ADR liquidity and lower home share liquidity, in terms of cha...

This study presents the empirical results for the relationship between the use of hedging techniques and the characteristics of UK multinational enterprises (MNEs). All the firms in the sample hedge foreign exchange (FX) exposure. The results indicate that UK firms focus on a very narrow set of hedging techniques. They make much greater use of derivatives than internal hedging techniques. The d...

This paper offers a continuous time, general equilibrium model where a risky asset is traded among risk-averse overconfident investors. Two kinds of overconfidence are introduced: investors exhibit relative overconfidence if each investor believes her model is better than others’ and aggregate overconfidence if they believe signals have more information content than those in the true model. Rel...

In this paper we develop a dynamic model for integer counts to capture the discreteness of price changes for financial transaction prices. Our model rests on an autoregressive multinomial component for the direction of the price change and a dynamic count data component for the size of the price changes. Since the model is capable of capturing a wide range of discrete price movements it is part...

This study estimates the value of the early exercise premium in American put option prices using Swedish equity options data. The value of the premium is found as the deviation of the American put price from European put-call parity, and in addition a theoretical estimate of the premium is computed. The empirically found premium is also used in a modified version of the control variate approach...

We propose a technique to avoid spurious detection of jumps in high frequency data via an explicit thresholding on available test statistics. We prove that it eliminates asymptotically all spurious jumps. Monte Carlo results show that it performs also well in finite samples. Our empirical investigation of Dow Jones stocks reveals that the spurious detections represent up to 50% of the jumps det...

To capture trader heterogeneity in a market microstructure setting, we model a trader’s option to trade as an optimal stopping problem. This option to trade is much like a firm’s option to invest in the real options literature. The optimal bid-ask prices quoted by any trader are functions of the joint evolution of their own private value and the private value of their intended trading counterpa...

We study the properties of foreign exchange risk premia that can explain the forward bias puzzle – the tendency of high-interest rate currencies to appreciate rather than depreciate. These risk premia arise endogenously from the no-arbitrage condition we impose on the relation between the term structure of interest rates and exchange rates, and they compensate for both currency risk and interes...

A continuous time econometric modelling framework for multivariate financial market event (or ‘transactions’) data is developed in which the model is specified via the vector conditional intensity. Generalised Hawkes models are introduced that incorporate inhibitory events and dependence between trading days. Novel omnibus specification tests based on a multivariate random time change theorem a...

To investigate how political tastes influence portfolio decisions, we exploit the mandatory disclosure of equity holdings made by U.S. Congress members and a continuous measure of ideology based on their voting records. By doing so, we address methodological issues facing the literature on political tastes and investment decisions. We find that politicians with similar beliefs hold similar equi...
