We exploit a natural experiment in which two professionals compete in a one-stage contest without strategic motives and where one contestant has a clear exogenous psychological momentum advantage over the other in order to estimate the causal effect of psychological momentum on performance. We...

This paper explores the relationship between non-standard types of employment and mental health. The analysis uses data on workers from the first seven waves of the British Household Panel Study, 1991-97. Four different types of non-standard employment (non-standard contracts, places, times, and...

We demonstrate why meaningful work, i.e. job-related activities that individuals view as purposeful and worthwhile, matters to labour economists. Building on self-determination theory, which specifies the roles of autonomy, competence, and relatedness as preconditions for motivation, we are the...

We investigate the effect of variations in the price of opium in Afghanistan on per capita dispensation of prescription opioids in the US. Quarterly county-level data for 2003-2016 indicate that reductions in opium prices significantly increase the quantity of opioids prescribed. The increase...

In this paper we investigate the dual role of supply restrictions and drug treatment in combating the concurrent rise of opioid abuse and suicide in the United States over the last two decades. We find that supply-side interventions decrease suicides in places with strong addiction-help...

It is a puzzle why people often evaluate consequences of choices separately (narrow bracketing) rather than jointly (broad bracketing). We study the hypothesis that a present-biased individual, who faces two tasks, may bracket his goals narrowly for motivational reasons. Goals motivate because...

This study is an empirical assessment of the impact of the drug decriminalization policy followed by Portugal in July, 2001. We investigate especially the impact of the policy change on the price of illicit drugs. The analysis is performed using a difference-in-differences approach and a...

We investigate behavioral responses to a staggered disruption in the supply of prescription opioids across U.S. states: the introduction of electronic Prescription Drug Monitoring Programs (PDMPs). Using administrative datasets, we find PDMPs curtail the proliferation of prescription opioids....

Across Europe, there are many differing opinions on whether workplace employee representation should be encouraged or discouraged. Yet there is very little evidence on the variations in workplace employee representation across Europe or the reasons for this. We use a workplace survey covering 27...
