In an environment with extensive corruption where much of the population evades paying their full taxes due, we tackle the question of optimal taxation when constituencies with opposing objectives (the poor and the rich) push tax policy in different directions. We think in terms of a government...

We study whether misinvoicing in international trade is reflected in cross-border bank accounts as reported by offshore financial centres. We show that residents hold more offshore wealth when local misinvoicing practices thrive, especially for under-invoiced exports of natural resources. These...

This paper constructs time series of global profit shifting covering the 2015–19 period, during which major international efforts were implemented to curb profit shifting. We find that (i) multinational profits grew faster than global profits, (ii) the share of multinational profits booked in tax...

Corporate tax avoidance hampers domestic revenue mobilization and, with it, the development of lower- and middle-income countries. While a wide range of studies has shed light on the magnitude of profit shifting by multinational corporations, the indirect costs of this behaviour is underexplored...

We show that legal opacity is a strong factor in drug trafficking. We develop a new framework that illustrates how legal opacity influences countries’ seizure rates. Legal opacity reduces the detection of illicit flows and increases their volumes because it lowers trafficking costs. We use detailed...

– Evidence from Ecuadorian transaction data
This study leverages a unique data set on the universe of transactions exiting the Ecuadorian economy to estimate the tax-price elasticity of demand for tax-sheltering activities using offshore fiscal havens.

We investigate the effect of economic sanctions on trade flows in countries sharing a border with the sanctioned state. On the one hand, trade models suggest that trade flows should decrease as sanctions disrupt trading routes and economic ties with suppliers and customers. On the other hand...

Illicit financial flows (IFFs) constitute a major challenge for development in the Global South, as domestic resource mobilization is imperative for providing crucial public services.
