This paper presents estimates of the macroeconomic effects, and resulting dynamic impact on revenues, of the House GOP tax plan announced in June 2016. The estimates were produced in two ways. One set of estimates uses a combination of TPC’s Keynesian model (to project short-run effects on...

Differences in state taxes paid and benefits received for immigrants and native-born Americans are driven by differences in demographic characteristics. Spending on immigrants is somewhat greater primarily because they have more school age children. Fiscal impacts also vary by state. This brief...

States vary in how much governments collect in revenue and spend on goods and services. To understand the sources of these differences, we examined what states could raise (revenue capacity) and would spend (expenditure need) if they followed national averages, taking into account their own...

Following the practice of official government estimators, we use a Keynesian model to estimate the short-term effects of policy changes on output relative to its full-employment level. That model assumes...

The synthetic control method is an increasingly popular method for state policy evaluation. It provides quantitative support for case studies by creating a synthetic control region that simulates what the outcome path of a region would be if it did not undergo a particular policy intervention....

Territorial tax systems require clear rules to distinguish between taxable domestic and exempt foreign-source income. Defining the source of a multinational company’s profits is difficult, however, especially for profits that are attributable to intangible assets. Shifting of reported profits to...
