Do new digital consumption channels of music depress sales in old physical ones, or are they complementary? To answer this question, we exploit product-level variations in prices of about 30 million sales and streams of over 300 thousand products observed weekly between 2014 and 2017 for the entire...

By conducting a field experiment, we investigate whether consumers value expert opinion labels on wine as a form of reducing asymmetric information about product quality. We use two types of data. First, we use a macro-level monthly-product-store dataset, collected before and after our field...

The producers of electricity using dispatchable plants rely on partially flexible technologies to match the variability of demand and intermittent renewables. We analyse flexibility in a two-stage decision process where production decided at the last moment is more costly than if it is planned in...

This paper examines the performance of nonlinear short‐term forecasts of noncausal processes from closed‐form functional predictive density estimators. The processes considered have mixed causal–noncausal MAR(1, 1) dynamics and non‐Gaussian distributions with either finite or infinite variance. The...

Money represents a cornerstone of human modern economies and how money emerged as a medium of exchange is a crucial question for social sciences. Although non-human primates have not developed monetary systems, they can estimate, combine and exchange tokens. Here, we evaluated quantity–quality...

Philosophers and scientists have long debated the nature of human social interactions and the prevalence of mutual dependence, conflict of interests, and power asymmetry in social situations. Yet, there is surprisingly little empirical work documenting the patterns of interdependence that people...
