The elasticities of taxable (ETI) and broad income (EBI) are key parameters in optimal tax and welfare analysis. To examine the large variation in estimates found in the literature, I conduct a comprehensive meta-regression analysis of elasticities that measure behavioral responses to income...

We study the effect of inflowing remittances - a major source of capital for many countries - on tax-revenues and tax-policy. Instrumenting remittances with changes in the oil-price interacted with a country's distance to oil-producing countries, we find that remittances have a large positive...

We advance the literature on political budget cycles by testing separately for cycles in expenditures for elections in the legislative and the executive. Using municipal data, we can separately identify these cycles and account for general year effects. For the executive branch, we show that it...
