This paper studies the effect of investor's bounded rationality on market dynamics. In an order driven market, we consider a few-types model where two risky assets are exchanged. Agents differ by their behavior, knowledge, risk aversion and investment horizon. The investor's demand is defined by...

This paper examines whether the baseline Mortensen-Pissarides matching model can account for the housing market facts, namely, the existence of price dispersion, the positive correlation between housing price and trading volume, and between housing price and time-on-the-market. Our main finding...

We study the liquidity, defined as the size of the trading volume, in a situation where an infinite number of agents with heterogeneous beliefs reach a trade-off between the cost of a precise estimation (variable depending on the agent) and the expected wealth from trading. The "true" asset...

We study the liquidity, de ned as the size of the trading volume, in a situation where an in nite number of agents with heterogeneous beliefs reach a trade-o between the cost of a precise estimation (variable depending on the agent) and the expected wealth from trading. The \true" asset price is...

This article extends the previous literature on the Tobin tax and financial transaction tax. We investigate the linkages between trading volumes and transaction costs using both a linear and a nonlinear methodology. In stark contrast with previous studies, we consider the possibility that our...

This article analyses the impact of oil price on bond risk premiums issued by emerging economies. No empirical study has yet focussed on the effects of the oil price on government bond risk premiums. We develop a model of credit spread with data from the EMBIG index of seventeen countries, from...

We provide a discipline for belief formation through a model of subjective beliefs, in which agents hold strategic beliefs. More precisely, we consider beliefs as a strategic variable that agents can choose (consciously or not) in order to maximize their utility at the equilibrium. These...

La Vallée (1968), in the expected utility model, gives a sufficient condition for positivity of the bid-selling spread. In this article, we show that this sufficient condition, namely decreasing absolute risk aversion (DARA) is in fact necessary. Moreover, we prove that the expected utility...

We build a two-country open-economy monetary union DSGE model in order to explain some macroeconomic imbalances in the euro area. We fo cus on the role of cyclic al behaviour of public spending and sovereign risk premium. Pro-cyclical primary public expenditures in one country do not lead to...

In this paper, a fully choice-based theory of disappointment is developed. It encompasses, as particular cases, EU theory, Gul's theory of disappointment (1991) and the models of Loomes and Sugden (1986). According to the new theory, the risk premium of a random prospect is the sum of two...
