Rational trader risk
Kondor, Peter - London School of Economics (LSE) - 2004
Allowing for a richer information structure than usual, we show that rational traders’ calculation with short-term price fluctuations may heavily influence their behaviour even if the interim price is not influenced by non-rational agents i.e. there is no noise trader risk. Instead, traders...

The international diversification puzzle is not worse than you think
Julliard, Christian - London School of Economics (LSE) - 2002
This paper offers two main contributions. First, it shows how the Baxter and Jermann (1997) claim that, once we consider human capital risk, the international diversification puzzle is worse than we think, is based on an econometric misspecification rejected by the data. Second, it outlines how,...

Rational asset pricing implications from realistic trading frictions
Zigrand, Jean-Pierre - London School of Economics (LSE) - 2002
it is shown that arbitrage opportunities occur which could not have occured in a standard model. A certain and precise … degree of informativeness of prices to the traders is lost because the decision making process becomes endogenously segmented … and decentralized within the same decision making entity (distinct "trading desks"). It is shown that, compared to the …

We provide a historical perspective focusing on Ziemba's experiences and research on the bond-stock earnings yield differential model (BSEYD) starting from when he first used it in Japan in 1988 through to the present in 2014. The model has called many but not all crashes. Those called have high...

Dynamic equilibrium with rare events and heterogeneous Epstein-Zin investors
Chabakauri, Georgy - London School of Economics (LSE) - 2015
We consider a general equilibrium Lucas (1978) economy with one consumption good and two heterogeneous Epstein-Zin investors. The output is subject to rare large drops or, more generally, can have non-lognormal distribution with higher cumulants. The heterogeneity in preferences generates excess...

Understanding portfolio efficiency with conditioning information
Peñaranda, Francisco - London School of Economics (LSE) - 2009
Contrary to the classic framework of passive strategies, if investors exploit return predictability through active strategies then there is a tension between the mean-variance frontiers that drive empirical work and the mean-variance preferences that are used in finance theory. We show that...
