We analyse daily lead-lag patterns in US equity and credit default swap (CDS) returns. We first document that equity returns robustly lead CDS returns. However, we find that the CDS-lag is due to <I>common</I> (and not firm-specific) news and arises predominantly in response to <I>positive</I> (instead of...</i></i>

U.S. trading in non-U.S. stocks has grown dramatically. Round-the-clock, these stocks trade in the home market, in the U.S. marketand, potentially, in both markets simultaneously. We use a state space model to study 24-hour price discovery. As opposed to thestandard "variance ratio'' approach,...

The obligation to pay bride wealth at marriage is usually associated with thecontinuation of the lineage or considered a compensation for the loss of laborfor the family that provides the bride. In this paper a different interpretationis advanced. The obligation to pay of bride wealth is seen as...

Volume 5(1), pages 78-114.<P> The main purpose of this paper is to evaluate the effect of crude oil price on global fertilizer prices in both the mean and volatility. The endogenous structural breakpoint unit root test,...</p></i>

Most stock exchange regulators around the world reacted to the 2007-2009 crisis byimposing bans or regulatory constraints on short-selling. Short-selling restrictions wereimposed and lifted at different dates in different countries, often applied to different sets ofstocks and featured different...

For many assets, trading is fragmented across multiple exchanges. Price discovery measures summarize the informativeness of trading on each venue for discovering the asset’s true underlying value. We explore intraday variation in price discovery using a structural model with time-varying...

This note clarifies the relation between two competing definitions of the contribution to pricediscovery in market microstructure models: (i) the information share and (ii) the common factorcomponent weight. It is demonstrated that the two measures are closely related, but that only...

Actual portfolios contain fewer stocks than are implied by standard financial analysis that balances the costs of diversification against the benefits in terms of the standard deviation of the returns.

This discussion paper led to a publication in the <I>Journal of Economic Dynamics and Control</I>. Volume 31(6), pp. 1938-1970.<P> We estimate a dynamic asset pricing model characterized by heterogeneous boundedly rational agents. The fundamental value of the risky asset is publicly available to all...</p></i>

This paper surveys work on dynamic heterogeneous agent models (HAMs) in economics and finance. Emphasis is given to simple models that, at least to some extent, are tractable by analytic methods in combination with computational tools. Most of these models are behavioral models with boundedly...
