The disposition effect refers to the empirical fact that investors have a higher propensity to sell risky assets with capital gains compared to risky assets with capital losses, and it has been associated with low trading performance. We use a stock trading laboratory experiment to investigate...

We use measures of neural activity provided by functional magnetic resonance imaging (fMRI) to test the "realization utility" theory of investor behavior, which posits that people derive utility directly from the act of realizing gains and losses. Subjects traded stocks in an experimental market...

type="main" <title type="main">ABSTRACT</title> <p>We conduct a study in which subjects trade stocks in an experimental market while we measure their brain activity using functional magnetic resonance imaging. All of the subjects trade in a suboptimal way. We use the neural data to test a “realization utility”...</p>

We present a dynamic model of free riding in which n infinitely lived agents choose between private consumption and contributions to a durable public good g. We characterize the set of continuous Markov equilibria in economies with reversibility, where investments can be positive or negative; and...

We study the Markov equilibria of a model of free riding in which n infinitely lived agents choose between private consumption and irreversible contributions to a durable public good. We show that the set of equilibrium steady states converges to a unique point as depreciation converges to zero....

World democracies widely differ in electoral rules, as well as in legislative, executive or legal institutions. Different institutional environments induce different mappings from electoral outcomes to the distribution of power. We explore how these mappings affect voters' participation to an...

We present a theoretical model of the provision of a durable public good over an infinite horizon. In each period, there is a societal endowment of which each of n districts owns a share. This endowment can either be invested in the public good or consumed. We characterize the planner's optimal...

We present a legislative bargaining model of the provision of a durable public good over an infinite horizion. In each period, there is a societal endowment which can either be invested in the public good or consumed. We characterize the optimal public policy, defined by the time path of...

This paper provides a direct test of the causal link from electoral rules to economic policy. Our theoretical model delivers unambigous predictions on the interaction between institutions and a time varying event, namely the unemployment rate in pivotal and non-pivotal districts. We use local...
