Online labor markets have great potential as platforms for conducting experiments, as they provide immediate access to a large and diverse subject pool and allow researchers to conduct randomized controlled trials. We argue that online experiments can be just as valid - both internally and...

In a model of evolution driven by conflict between societies more powerful states have an advantage. When the influence of outsiders is small we show that this results in a tendency to hegemony. In a simple example in which institutions differ in their "exclusiveness" we find that these...

This paper studies the interactions between an individual's self esteem and his social environment in the workplace, at school, and in personal relationships. Because a person generally has only imperfect knowledge of his own abilities, people who derive benefits from his performance (parent,...

This paper explores the power of threats in the absence of binding commitment. The threatener cannot commit to carrying out the threat if the victim refuses payment, and cannot commit to not carrying out the threat if payment is made. If exercising the threat is costly to the threatener, then...

This paper investigates the association between greater income inequality, de-facto fiscal space, and sovereign spreads. Using data from 50 countries in 2007, 2009 and 2011, we find that higher income inequality is associated with a lower tax base, lower de-facto fiscal space, and higher...

How much additional tax revenue can the government generate by increasing labor income taxes? In this paper we provide a quantitative answer to this question, and study the importance of the progressivity of the tax schedule for the ability of the government to generate tax revenues. We develop...

We estimate the sensitivity of Internet retail purchasing to sales taxes using data from the eBay marketplace. Our first approach exploits the fact that seller locations are revealed only after buyers have expressed interest in an item by clicking on its listing. We use millions of location...

We study the short-term impact of Connecticut's Jobs First welfare reform experiment on women’s labor supply and program participation decisions. A non-parametric optimizing model is shown to restrict the set of counterfactual choices compatible with each woman's actual choice. These revealed...

This paper investigates how tax changes for different income groups affect aggregate economic activity. I construct a measure of who received (or paid for) tax changes in the postwar period using tax return data from NBER's TAXSIM. I aggregate each tax change by income group and state. Variation...

This paper focuses on two core tax design issues that arise in addressing current fiscal challenges It first explores the idea, prominent in troubled Eurozone countries, of a 'fiscal devaluation:' shifting from social contributions to the VAT as a way to mimic a nominal devaluation. Empirical...
