Traditionally, econometric research on social interaction effects has used fairly large social groups (schools, Census tracts, etc.). However, new data which describes the behavior of much smaller peer groups is becoming available. This paper analyzes the behavior of "small neighborhoods" in the...

The objective of this work is to evaluate the impact of a social security system on the well-being of each individual in the economy and to challenge the measures commonly used in this type of policy analysis. We show that measures based on the notion of actuarial fairness do not measure...

Agent based models take into account limited rational behaviour of individuals acting on financial markets. Explicit simulation of this behaviour and the resulting interaction of individuals provide a description of aggregate financial market time series. At least for some parameter settings,...

In this paper, we investigate the welfare implications of alternative financial market structures in a two-country endowment economy model. In particular, we obtain an analytic expression for the expected lifetime utility of the representative household when sovereign bonds are the only...

In this paper, I examine the properties of the class of generalized empirical likelihood estimators of moment-condition models. These nonparametric likelihood estimators satisfy exactly the moment conditions and automatically remove any bias due to a lack of centering. Moreover, the bias of the...

This paper presents an adaptive learning model for market-making under the reinforcement learn-ing framework. Reinforcement learning is a learning technique in which agents aim to maximize the long-term accumulated rewards. No knowledge of the market environment, such as the order arrival or...

Ways of finding a maximum skewness portfolio, with given return, variance and kurtosis, are presented. The methods take advantage of the special shape of the efficient portfolios manifold. Simpler solutions are obtained if the higher moments tensor has some particular structures. The problem of...

Household production plays an important role in aggregate economic activity. It constitutes between 20 and 50 percent of the value of gross national product in several industrialized countries. We study cross-country differences and similarities in the dynamic behavior of production activities...

This article analyzes the trade-off between ÏcautionÓ and ÏintensityÓ in the use of the control variable in a one-state one-control dynamic stochastic quadratic linear optimization problem with discount factor. It studies the effects that changes in uncertainty of the control parameter have...
