We study the interplay between scientific progress and culture through text analysis on a corpus of about eight million books, with the use of techniques and algorithms from machine learning. We focus on a specific scientific breakthrough, the theory of evolution through natural selection by...

We develop a theory of interstate conflict in which the degree of genealogical relatedness between populations has a positive effect on their conflict propensities because more closely related populations, on average, tend to interact more and develop more disputes over sets of common issues. We...

To discuss experimental results without discussing how they came about makes sense when the results are robust to the way experiments are conducted. Experimental results, however, are - arguably more often than not - sensitive to numerous design and implementation characteristics such as the use...

Economic research shows that candidates have a higher chance of getting (re-)elected when they have the luck that the world economy does well even though this is beyond their control and unrelated to their competence. Psychological research demonstrates that candidates increase their chances if...

Does temperature affect economic performance? Has temperature always affected social welfare through its impact on physical and cognitive function? While many studies have explored the indirect links between climate and welfare (e.g. agricultural yield, violent conflict, or sea-level rise), few...

Duverger (1954) noted that changes in electoral systems will have two types of effects: mechanical effects, and reactions of political agents in anticipation of these, which he referred to as psychological effects. It is complicated to empirically separate the two effects since these occur...

We examine how the net worth of billionaires relates to their looks, as rated by 16 people of different gender and ethnicity. Surprisingly, their financial assets are unrelated to their beauty; nor are they related to their educational attainment. As a group, however, billionaires are both more...

The importance of evolutionary forces for comparative economic performance across societies has been the focus of a vibrant literature, highlighting the roles played by the Neolithic Revolution and the prehistoric "out of Africa" migration of anatomically modern humans in generating worldwide...
