We leverage insights from machine learning to optimize the tradeoff between bias and variance when estimating economic models using pooled datasets. Specifically, we develop a simple algorithm that estimates the similarity of economic structures across countries and selects the optimal pool of...

We develop a framework to nowcast (and forecast) economic variables with machine learning techniques. We explain how machine learning methods can address common shortcomings of traditional OLS-based models and use several machine learning models to predict real output growth with lower forecast...

This essay critically revisits the roles and influences of tax havens in the world economy. It combines various massages of available studies in one scheme, documents a number of observations, and proposes several issues for future research. -- tax havens ; tax avoidance ; tax evasion ;...

How did the rise of multinational enterprises (MNEs) put pressure on the prevailing international corporate tax framework? MNEs, and firms with market power, are not new phenomena, nor is the corporate income tax, which dates to the early 20th century. This prompts the question, what is...

Excess profit taxes (EPTs) emerge as an option to contribute to the extra needed revenues, avoiding a general increase in corporate tax rates, while having the prospect to serve as a gateway to converge toward a permanent efficient rent tax instaed of the corporate income tax. General unilateral...

We study the effects of federal purchases on firm investment using a novel panel dataset that combines federal procurement contracts in the United States with key financial firm-level information. Using panel fixed-effect models, propensity score matching, and inverse probability weighting...

We estimate the revenue implications of a Destination Based Cash Flow Tax (DBCFT) for 80 countries. On a global average, DBCFT revenues under unchanged tax rates would remain similar to the existing corporate income tax (CIT) revenue, but with sizable redistribution of revenue across countries....
