We provide a macroeconomic theory where demand for goods has a productive role. A search friction prevents perfect matching between producers and potential customers. Larger demand induces more search, which in turn increases GDP and measured TFP. We embed the product-market friction in a...

Switzerland could be considered as a test case for international corporate-tax policy coordination. It is a federation of 26 fiscally autonomous cantons that have been taxing corporate profits more or less independently for over a century. We document and discuss corporate taxation in...

This paper studies how differences in labor market regulations shape countries' comparative advantage in the cross-border provision of labor-intensive services, using administrative data in Europe for the last two decades. I exploit exogenous variation in labor taxes and minimum wages faced by...

Tax harmonization entails a uniform rate that may not suit all governments. Harmonization can advance collective governmental objectives only if the standard deviation of tax rates is less than the average downward effect of tax competition on rates. Since an efficient harmonized tax rate undoes...

Many multinational firms (MNEs) pay low or no corporation tax in high-tax countries because they shift taxable income to tax havens. We incorporate nonconvex costs of profit shifting and unobserved heterogeneity in profit-shifting ability in the MNEs' value maximization problem to study...

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...

Recent estimates of US top wealth shares obtained by capitalizing income tax returns (Saez and Zucman, 2020; Smith, Zidar and Zwick, 2022) are close in both levels and trends except for the top 0.01% where a large discrepancy remains. We examine this difference and, using public data, quantify three...

This paper provides new insights into the nature of entrepreneurship using a novel panel dataset based on U.S. administrative data from the Internal Revenue Service and the Social Security Administration. These data are used to analyze patterns of income growth and determinants of...

Profit shifting by multinational corporations is thought to reduce tax revenue around the world. We analyze the introduction of standard regulations aimed at limiting profit shifting. Using administrative tax and customs data from Chile in difference-in-differences event-study designs, we find...

An important but poorly understood form of firm tax evasion arises from the use of "ghost firms"--fake firms that issue fraudulent receipts so that their clients can claim false deductions. We provide a unique window into this global phenomenon using transaction-level tax data from Ecuador....
