This paper employs unique data on export transactions and corporate tax returns of UK multinational firms and finds that firms manipulate their transfer prices to shift profits to lower-taxed destinations. It uncovers three new findings on tax-motivated transfer mispricing in real goods. First,...

The Mirrlees Review recommends that commodity taxation should in general be uniform, but with some goods consumed in conjunction with labour supply (such as child care) left untaxed. This paper examines the validity of this claim in an optimal income tax framework. Contrary to the recommendation...

We present a model of income tax avoidance with heterogeneous agents, assuming the presence of a comparison income effect and of a psychic cost (disutility) of tax dodging. We analyse the policy preferences of the agents, and identify a median-voter political equilibrium. Paralleling previous...

We study behavioral responses to local income taxes exploiting a special tax regime which applies to foreign employees residing in Switzerland. The used institutional setting generates two thresholds through which locally heterogeneous taxation is assigned: An income threshold at 120,000 Swiss...

We study charitable giving within social groups. Exploiting a unique dataset, we establish three key relationships between social group size and fundraising outcomes: (i) a positive relationship between group size and the total number of donations; (ii) a negative relationship between group size...

Much fundraising is done by individuals within existing social groups. Exploiting a unique dataset, we demonstrate:(i) a positive relationship between social group size and the number of donations; (ii) a negative relationship between group size and the size of individual donations; (iii) no...

This paper estimates the intensive and extensive-margin tax-price elasticities of giving using UK administrative tax return data, exploiting variation from a large tax reform. Using a variety of estimation methods and new instruments for the tax-price of giving, we find an intensive-margin...

Using aggregate data on U.S. multinational firms' activities, we document the impact of tax havens on the organization and trade of multinational firms. Conventional wisdom says that MNEs set up foreign sales platforms close to large markets to benefit from the proximity to consumers. We show,...

The issue of tax-motivated income shifting within multinational firms has attracted increasing global attention in recent years. It is of central importance to many current policy debates, including those related to recent initiatives by the OECD on base erosion and profit shifting (BEPS) and to...

This paper estimates the size and macroeconomic effects of base erosion and profit shifting (BEPS) using a computable general equilibrium model designed for corporate taxation and multinationals. Our central estimate of the impact of BEPS on corporate tax losses for the EU amounts to €36...
