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...

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...

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...

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...

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,...

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...

The Tax Cuts and Jobs Act of 2017 (TCJA) marked the first time in three decades that material changes were made to the corporate tax code of the United States. We use TCJA as a quasi natural experiment to estimate the impact of changes in user cost of capital on investment. Following the method...

Economists have widely varying opinions of how corporate taxation affects aggregate investment, output, and wages. This disagreement reflects a 60-year history of misapplication of the neoclassical theory of investment to interpret empirical work and guide policy analysis. In this article I...

In the United States, unemployment insurance (UI) is funded through employer-side payroll taxes that are experience-rated based on previous UI claims. States differ significantly with respect to the financing of their programs, and a majority of state programs do not currently meet minimum UI...
