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...

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...

We study 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...

Policy researchers often have to estimate the future effect of imposing a policy in a particular location. There is often historical information on the effects of similar policies in other jurisdictions, but no information on the effects of the policy in the jurisdiction in question, and the...

For recently released prisoners, the minimum wage and the availability of state Earned Income Tax Credits (EITCs) can influence both their ability to find employment and their potential legal wages relative to illegal sources of income, in turn affecting the probability they return to prison....

We propose a novel method that infers the employment effect of a minimum wage increase by comparing the number of excess jobs paying at or slightly above the new minimum wage to the missing jobs paying below it. To implement our approach, we estimate the effect of the minimum wage on the...

Using variation in minimum wages across cities and controlling for differences in business-cycle factors and long-run local economic trends, we find that following minimum wage increases, both prices and nominal spending rise modestly. These gains are larger for certain sub-categories of goods...

This study investigates whether minimum wage increases in the United States affect an important non-market outcome: worker health. To study this question, we use data on lesser-skilled workers from the 1993-2014 Behavioral Risk Factor Surveillance Surveys coupled with differences-in-differences...
