Exploiting a new global macro-historical database of effective tax rates, we uncover an intriguing pro-tax-capacity effect of international trade. While effective capital tax rates have fallen in developed countries, they have risen in developing countries since the mid-1990s. Event studies of trade liberalization shocks and instrumental variable regressions show that a significant share of this rise can be explained by trade integration, which increases the share of output produced in large corporations, where effective taxation of capital is higher. In contrast to a widely held view, globalization appears in many countries to have supported the ability of government to tax capital.

This paper studies individual and social motives in tax evasion. We build a simple dynamic model that incorporates these motives and their interaction. The social motives underpin the role of norms and is the source of the dynamics that we study. Our empirical analysis exploits the adoption in 1990 of a poll tax to fund local government in the UK, which led to widespread evasion. The evidence is consistent with the model’s main predictions on the dynamics of evasion.

This paper studies the role of technology in local-government tax collection capacity in the developing world. We first conduct a new census of all local governments in Ghana to document a strong association between technology use and property tax billing, collection and enforcement. We then randomize the use of a new revenue collection technology within one large municipal government. Revenue collectors using the new technology delivered 27 percent more bills and collected 103 percent more tax revenues than control collectors. Collectors using the new technology learned faster about which households in their assigned areas were willing and able to make payments. We reconcile these experimental findings in a simple Beckerian time-use model in which technology allows revenue collectors to better allocate their time towards households that are the most likely to comply with taxpaying duties. The model's predictions are consistent with experimental evidence showing that treatment collectors are more likely to target households with greater liquidity, income, awareness of taxpaying duties, and satisfaction with local public goods provision.

Can taxes on consumption redistribute in developing countries? Contrary to consensus, we show that taxing consumption is progressive once we account for informal consumption. Using household expenditure surveys in 32 countries we proxy for informal consumption using the type of store where purchases occur. We find that the budget share spent in informal stores steeply declines with income, so that the effective tax rate of a broad consumption tax rises with income. Our findings imply that the widespread policy of exempting food from taxation cannot be justified on equity grounds in low income-countries

This paper shows how the increase in information trails through the long-run transition from self-employment to employee-jobs explains the rise of the modern income tax system. I construct a new database which covers 100 household surveys across countries at different income levels and 140 years of historical data within the US (1870-2010). Using these data, I first establish four new stylized facts: 1) within country, the share of employees increases over the income distribution, and increases at all levels of income as a country develops; 2) the income tax exemption threshold moves down the income distribution as a country develops, tracking employee growth; 3) the employee share above the exemption threshold is maximized and remains constantly high; 4) decreases in the exemption threshold are strongly associated with increases in tax collection. These findings are consistent with a model where a high employee share is a necessary condition for effective taxation and where the rise in income covered by information trails through increases in employee share drives expansion of the income tax base. To provide a causal estimate of employee share on income tax systems, I study a state-led US development program implemented in the 1950s-60s which increased the level of employee share. The identification strategy exploits within-state changes in court-litigation status which generate quasi-experimental variation in the effective implementation date of the program. I find that the exogenous increase in employee share is associated with an expansion of the state income tax base and an increase in state income tax revenue.
