In this paper, citizens vote in order to influence the election outcome and in order to signal their unobserved characteristics to others. The model is one of rational voting and generates the following predictions: (i) The paradox of not voting does not arise, because the benefit of voting does...

We present a theory explaining the impact of ability tracking on academic performance based on grading policies. Our model distinguishes between initial ability, which is mainly determined by parental background, and eagerness to extend knowledge. We show that achievements of low ability...

Conventional wisdom has it that policy innovation is better promoted in a federal rather than in a unitary system. Recent research, however, has provided theoretical evidence to the contrary: a multi-jurisdictional system is characterized - due to the existence of a horizontal information...

A multi-jurisdictional system is thought to improve, through yardstick competition, accountability. At the same time equalization programs, a common feature of multijurisdictional systems, are thought to be a prerequisite for both efficiency of the internal market and the equity objective of the...

Border Carbon Adjustment Mechanisms (BCAMs) are becoming reality in the EU and elsewhere, and recur—in very different form—in U.S. legislative proposals. But they remain contentious, with features and differences that leave the underlying welfare rationale and implications unclear. Exploring...

This paper identifies conditions under which, starting from any tax distorting equilibrium, destination- and origin-based indirect tax-harmonizing reforms are potentially Pareto improving in the presence of global public goods. The first condition (unrequited transfers between governments)...

This paper explores the role of trade instruments in globally efficient climate policies, focusing on the central issue of whether border tax adjustment (BTA) is warranted when carbon prices differ internationally. It shows that tariff policy has a role in easing crosscountry distributional...

This paper explores the role of information transmission and misaligned interests across levels of government in explaining variation in the degree of decentralization across countries. Within a two-sided incomplete information principal-agent framework, it analyzes two alternative...

Recent literature has emphasized that redistributive grant systems may tend to internalize fiscal externalities arising from tax competition. This paper further explores the conditions under which local grant systems enforced by the state government will enhance efficiency. A system of...

We study the role of self-interest and social preferences in referenda. Our analysis is based on collective purchasing decisions of university students on deep-discount flat rate tickets for public transportation and culture. Individual usage data allows quantifying monetary benefits associated...
