Frontiers of economic research

Economics in Europe has seen impressive growth in recent years. But European economic research still lags behind the US in terms of productivity. This column discusses a new research project, ‘COEURE’, that will study the state of economic research in Europe and the mechanisms by which it is funded.

The black-white wage gap persists. Year after year, data tell us that black workers in the US earn less than their white counterparts. This column presents new evidence focused on the notion of race-specific social networks and ‘knowledge spillovers’. Data suggest that a black worker may be less able than an otherwise similar white worker to enjoy knowledge spillovers that arise in predominantly white work environments, suppressing their earnings.

Cultural transmission occurs both vertically – from one generation to the next – and, increasingly in modern times, horizontally – within generations and across populations. Using novel data for 74 countries, this column explores how genetic relatedness between populations affects the transmission of cultural traits. A pattern of positive and significant relationships is found between genetic distance and various measures of cultural distance, including language, religion, values, and norms. This implies that populations that are ancestrally closer face lower barriers to learning new ideas and behaviours from each other.

Football leagues around the world tend to be dominated by a tiny number of teams. This column applies Sutton’s theory of endogenous sunk costs to show that it’s all down to success begetting success, and success attracting more fans. Like big companies who dominate markets and still spend billions on advertising to maintain their market position, dominant teams remain dominant because they consistently win.

If your surname begins with a letter at the end of the alphabet, you might have had that sneaking suspicion that it meant you were always picked last for sports teams, or always had your exam paper marked last when your teacher was tired and unforgiving. This column suggests that you might well have been right. New evidence suggests that academic papers presented at the top of a list are cited more simply because they are the first thing you see. In the digital age, many academic papers are competing for the scant attention of readers, and this column’s results indicate that details like presentation order really matter.
