In this paperwe relate individual risk attitude as elicited by binary lotteries and certainty equivalents to market behavior. By analyzing 26 independent markets with a total of 280 participants we show that binary lottery choices and certainty equivalents are pootly correlated. Only lottery...

We study financial markets in which both rational and overconfident agents coexist and make endogenous information acquisition decisions. We demonstrate the following irrelevance result: when a positive fraction of rational agents (endogeneously) decides to become informed in equilibrium, prices...

The feedback frequency and the length of commitment are two important features of investment alternatives in intertemporal decision-making. So far, empirical research has shown that a lower feedback frequency combined with a longer binding period decreases myopia and thereby increases the...

We provide a detailed account of the portfolio of Italian households and its evolution, using repeated cross-sectional and panel data drawn from the 1989-95 Bank of Italy Survey of Household Income and Wealth. We offer an in-depth description of the lifetime pattern of asset holdings and their...

Generalizations of traditional preference criteria such as the Sharpe ratio, the information ratio and the Jensen alpha are obtained by maximizing a certain equivalent excess return (CER) under relevant investment conditions. They are increasing functions of CERs and therefore equivalent...

We study a competitive model in which market incompleteness implies that debt-financed firms may default in some states of nature and default may lead to the sale of the firms’ assets at fire sale prices when markets are illiquid. This incompleteness is the only friction in the model and the...

In complete markets economies (Sandroni [15]), or in economies with Pareto optimal outcomes (Blume and Easley [9]), the market selection hypothesis holds, as long as traders have identical discount factors. Traders who survive must have beliefs that merge with the truth. We show that in...

Risk a basic parameter of portfolio selection and its modelling involves some difficulties.

There are three crucial mathematical system concepts in Finance, which are either being confused or misapplied - uncertainty, complexity and rank. First, the concept of epistemic uncertainty is sufficient for modeling and the concept of probability is unnecessary. This is illustrated by...
