This research explores the persistent effect of the Neolithic Revolution on the evolution of life expectancy in the course of human history. It advances the hypothesis and establishes empirically that the onset of the Neolithic Revolution and the associated rise in infectious diseases triggered...

We empirically assess the effect of historical slavery on the African American family structure. Our hypothesis is that female single headship among blacks is more likely to emerge in association not with slavery per se, but with slavery in sugar plantations, since the extreme demographic and...

In this note, I address the trade-off between children’s health and parental preference toward similarity with children. In my model, better-off individuals mate genetically close partners and then use wealth to treat their children’s health problems, caused by inbreeding depression. As a...

Randomized controlled trials (RCTs) are increasingly prominent in economics, with pre-registration and pre-analysis plans (PAPs) promoted as important in ensuring the credibility of findings. We investigate whether these tools reduce the extent of p-hacking and publication bias by collecting and...

Amazon's Mechanical Turk is a very widely-used tool in business and economics research, but how trustworthy are results from well-published studies that use it? Analyzing the universe of hypotheses tested on the platform and published in leading journals between 2010 and 2020 we find evidence of...

Pre-registration is regarded as an important contributor to research credibility. We investigate this by analyzing the pattern of test statistics from the universe of randomized controlled trials (RCT) studies published in 15 leading economics journals. We draw two conclusions: (a)...

The empirical evidence on the inter-generational effects of maternal health interventions is inconclusive, particularly the impact on cognitive ability of children. In this paper, we study one such popular policy from India, viz, the Janani Suraksha Yojana (JSY) which is a agship health and safe...

In this paper we take a fresh look at the magnitude of the trade-off between caring informally for a parent and paid work. We adopt a simultaneous approach with a primary focus on how hours of care are influenced by hours of work rather than the other way round. We also investigate the role that...

Using German survey data, we show that performance pay is associated with a substantially lower gender hours gap. While performance pay increases the work hours of both men and women, the increase is much larger for women than for men. This finding persists in worker fixed effects estimates. We...

Many countries impose job search requirements as a condition of unemployment benefit receipt, but there is relatively little evidence on the efficacy of these requirements. Australian reforms in 1995 and 2003 saw groups of welfare recipients newly subjected to job search requirements, providing...
