When policymakers and private agents use models, the economists who design the model have an incentive to alter it in order to influence outcomes in a fashion consistent with their own preferences. I discuss some consequences of the existence of such ideological bias. In particular, I analyze...

We introduce and study the problem of manipulation of choice behavior. In a class of two-stage models of decision making, with the agent's choices determined by three "psychological variables," we imagine that a subset of these variables can be selected by a "manipulator." To what extent does...

The public finance literature demonstrates the equivalence between consumption and labor-income (wage) taxes. We introduce an experimental paradigm in which individuals make real labor-leisure choices and spend their earned income on real goods. We use this paradigm to test whether a...

Standard economic analysis assumes that people make choices that maximize their utility. Yet both popular discourse and other fields assume that people sometimes fail to make optimal choices and thus adversely affect their own happiness. Most social sciences thus frequently describe some...

Arguably, one of the most important developments in the field of applied economics during the last decades has been the emergence of systematic policy evaluation, with its distinct focus on the establishment of causality. By contrast to the natural sciences, the objects of our scientific...

Policy advice can help political actors design and implement institutional reforms through the generation of political and substantial legitimacy. This article clarifies the institutional pre-conditions of effective supply and transfer of policy advice with particular respect to the field of...

In this paper we use novel historical data on economics and social rights from the constitutions of 201 countries and an instrument variable strategy to answer two important questions. First, do economic and social rights provisions in constitutions reduce poverty? Second, does the strength of...

Resit exams – extra opportunities to do an exam in the same academic year – are widely prevalent in European higher education, but uncommon in the US. I present a simple theoretical model to compare rational student behavior in the case of only one exam opportunity versus the case of two...
