In this paper, we explore two factors that can limit arming and, more generally, the costs of enforcement within and across states: governance or the formal organizations and institutions that help define and enforce property rights, and norms, or the informal arrangements in settling potential...

We explore how peace or war can occur in the presence of commitment problems. These problems can be reduced by institutions of good governance or, alternatively, state capacity which (i) can be considered a collective good and (ii) can be improved through investments. We show how the likelihood...

In many instances of potential violent or non-violent conflict, the future strategic positions of adversaries are very different when there is open conflict than when there is settlement. Then, we show that as the future becomes more important, open conflict becomes more likely than settlement....

Economic growth has not led to a decline in religion despite past predictions that it would. I use a formal model of religious competition to show how economic growth produces counteracting effects on religious participation in an open religious market, while economic growth will have little...

The past decade has witnessed an explosion of interest in the scientific study of happiness. Economists, in particular, find that happiness increases in income but decreases in income aspirations, and this work prompts examination of how aspirations form and adapt over time. This paper presents...

Recent research distinguishes an individual's decision utility, inferred from her observed choices, from her experienced utility, which more closely matches the notion of happiness. Using various estimation techniques with a unique experimental data set, we test whether post-choice satisfaction...

In many instances of potential violent or non-violent conflict the future strategic positions of adversaries are very different when there is open conflict than when there is settlement. In such environments we show that, as the future becomes more important, open conflict becomes more likely...

We examine two factors that help explain the prevalence of conflict in low-income countries: that adversaries cannot enforce long-term contracts in arms, and that open conflict alters the future strategic positions of the adversaries differently than does peace. Using an infinite horizon model,...

In many instances of potential violent or non-violent conflict the future strategic positions of adversaries are very different when there is open conflict than when there is settlement. In such environments we show that, as the future becomes more important, open conflict becomes more likely...
