We present results from the rst large-scale international surveyon risk preferences, conducted in 45 countries. We show substantialcross-country dierences in risk aversion, loss aversion and probabilityweighting. Moreover, risk attitudes in our sample depend not only oneconomic conditions, but...

We study a number of large international military conflicts sinceWorld War II where we establish a news analysis as a proxy for theestimated likelihood that the conflict will result in a war. We findthat in cases when there is a pre-war phase, an increase in the warlikelihood tends to decrease...

Our paper explores the role of time preferences on household debt maturity choice. Wefind that in countries where people are more patient in the long term, planning horizons in householddebt portfolios are significantly longer, as the optimal maturity of loans is considerably higher.The...

The paper examines a game-theoretic evolutionary model of anasset market with endogenous equilibrium asset prices. Assetspay dividends that are partially consumed and partially rein-vested. The investors use general, adaptive strategies (portfo-lio rules), distributing their wealth between...

The pricing kernel puzzle is the observation that the pricing kernelmight be increasing in some range of the market returns. This paperanalyzes the pricing kernel in a nancial market equilibrium. If mar-kets are complete and investors are risk-averse and have common andtrue beliefs, the pricing...

This chapter gives an overview of current research in evolutionary -nance. We mainly focus on the survival and stability properties ofinvestment strategies associated with the Kelly rule. Our approach tothe study of the wealth dynamics of investment strategies is inspired byDarwinian ideas on...

Evolutionary nance studies the dynamic interaction of investment strategies in nancialmarkets. This market interaction generates a stochastic wealth dynamics on aheterogenous population of traders through the uctuation of asset prices and theirrandom payos. Asset prices are endogenously...
