The ability of humans to create and disseminate culture is often credited as the single most important factor of our success as a species. In this Perspective, we explore the notion of ‘machine culture’, culture mediated or generated by machines. We argue that intelligent machines simultaneously...

We test Le Play's (1875) hypothesis that the French Revolution contributed to France’s early fertility decline. In 1793, a series of inheritance reforms abolished local inheritance practices, imposing equal partition of assets among all children. We develop a theoretical framework that predicts a...

We consider the problem of sharing the cost of a fixed tree-network among users with differentiated willingness to pay for the good supplied through the network. We find that the associated value-sharing problem is convex, hence, the core is large and we axiomatize a new, computationally simple...

Most Western countries use a single discount rate to evaluate public investments and policies. This ignores the differential cost of risk, in a world where most risk markets exhibit surprisingly large prices of risk. The current discounting guidelines generate a misallocation of capital that...

Testosterone plays a role in mediating energetic trade-offs between growth, maintenance, and reproduction. Investments in a high testosterone phenotype trade-off against other functions, particularly survival-enhancing immune function and cellular repair; thus only individuals in good condition can...

The existence of transaction taxes reduces transactions, and in the case of housing, reduces household mobility and affects the costs of downsizing in dire times. We construct and estimate an overlapping generation model in which households are heterogeneous in age and earnings, and prudential...

In industrialized populations low male testosterone is associated with higher rates of cardiovascular mortality. However, coronary risk factors like obesity impact both testosterone and cardiovascular outcomes. Here we assess the role of endogenous testosterone on coronary artery calcium in an...

We study how temporary visa schemes can be designed to drive smugglers out of business while meeting labor market needs in host countries. After discussing their compatibility with a large range of policy objectives, we show how combining internal and external controls with a regulated market for...

This paper provides new identification results for finite mixtures of Markov processes. Our arguments yield identification from knowledge of the cross-sectional distribution of three (or more) effective time-series observations under simple conditions. We explain how our approach and results are...
