We exploit variation in National Insurance contributions (NICs) - the UK's system of social security contributions - and a large panel dataset to examine the effects of 35 years of employee and employer NICs reforms on labour cost (gross earnings plus employer NICs), hours of work and labour...

We quantify firms' compliance costs of regulation from 2002 to 2014 in terms of their labor input expenditure to comply with government rules, a primary component of regulatory compliance spending for large portions of the U.S. economy. Detailed establishment-level occupation data, in...

We examine the effects of Fair Trade (FT) certification of coffee on producers and households in Costa Rica. Examining the production dynamics of the universe of Costa Rican coffee mills from 1999-2014, we find that FT certification is associated with a higher sales price, greater sales, and...

We document the evolution of markups based on firm-level data for the US economy since 1950. Initially, markups are stable, even slightly decreasing. In 1980, average markups start to rise from 18% above marginal cost to 67% now. There is no strong pattern across industries, though markups tend...

From March to July 1933, industrial production rose 57 percent. We show that an important source of recovery was the effect of dollar devaluation on farm prices, incomes, and consumption. Devaluation immediately raised traded crop prices, and auto sales grew more rapidly in states and counties...

In a collaborative project with ten central banks, we have investigated the causes of the post-pandemic global inflation, building on our earlier work for the United States. Globally, as in the United States, pandemic-era inflation was due primarily to supply disruptions and sharp increases in...

During the recovery from the COVID-19 pandemic, international shipping and logistics capacity was strained, limiting the quantity of imports. We investigate the impact of an import constraint on inflation, following an increase in domestic demand. Whether the binding import constraint raises...

This paper presents evidence on the employment effects of recent minimum wage increases from a pre-specified research design that entailed committing to a detailed set of statistical analyses prior to 'going to' the data. Despite the limited data to which the pre-specified research design can be...

The minimum wage is increasingly viewed as an important tool for improving public health outcomes, including reducing childbearing among teenagers. Taken at face value, recently reported estimates suggest that raising the federal minimum wage to $15 per hour could reduce the number of teenage...

Interactions between redistributive policies can confront low-income households with complicated choices. We study one such interaction, namely the relationship between Medicaid eligibility thresholds and the minimum wage. A minimum wage increase reduces the number of hours a low-skilled...
