Minimum tax rules constrain only the lowest-tax jurisdictions. Because higher minimum tax rates expand the circle of affected countries and therefore the impact of any further changes, there can be dominated regions over which no parameter values would make a minimum tax efficient. Applying a...

Particulate matter (PM) is a major, clinically important air pollutant. A large portion of emitted PM crosses borders, damaging health outside of its originating jurisdiction, but due in part to technical obstacles these pollutant flows remain unregulated. Proposed attribution approaches assume...

A simple dynamic game is used for analyzing international environmental problems and climate agreements. Different countries are, over time, emitting as well as investing in green technology. In this framework, we can analyze the business-as-usual outcome, short vs. long term agreements,...

As billions of people in the developing world seek to increase their living standards, their aspirations pose a challenge to global efforts to cut greenhouse gas emissions. The emerging middle class are buying and operating energy intensive durables ranging from vehicles to air conditioners to...

This paper applies principles of adverse selection to overcome obstacles that prevent the implementation of Pigouvian policies to internalize externalities. Focusing on negative externalities from production (such as pollution), we consider settings in which aggregate emissions are known, but...

We study how international agreements can take advantage of domestic time-inconsistency problems in the context of environmental policies. For example, policymakers will prefer future policies to be sustainable, but find it tempting to raise consumption when being in office. We find the...

We document the rise of China in offshore capital markets. Chinese firms use global tax havens to access foreign capital both in equity and bond markets. In the last twenty years, China's presence went from raising a negligible amount of capital in these markets to accounting for more than half...

Switzerland could be considered as a test case for international corporate-tax policy coordination. It is a federation of 26 fiscally autonomous cantons that have been taxing corporate profits more or less independently for over a century. We document and discuss corporate taxation in...

This paper studies how differences in labor market regulations shape countries' comparative advantage in the cross-border provision of labor-intensive services, using administrative data in Europe for the last two decades. I exploit exogenous variation in labor taxes and minimum wages faced by...

Tax harmonization entails a uniform rate that may not suit all governments. Harmonization can advance collective governmental objectives only if the standard deviation of tax rates is less than the average downward effect of tax competition on rates. Since an efficient harmonized tax rate undoes...
