We provide some simple theoretical results that justify incorporating machinelearning in a standard linear instrumental variable setting, prevalent in empiri-cal research in economics. Machine learning techniques, combined with sample-splitting, extract nonlinear variation in the instrument that...

We use a randomized experiment in the Bundesbank Online Panel-Households (n ≈ 3, 900) to show that the estimated link between inflation expectations and household consumption flips sign depending on survey wording. This finding reconciles prior contradictory results and has direct implications for...

Sex-specific division of labour and the associated use of different subsistence techniques by males (e.g., hunting) and females (e.g., gathering) has played an important role in shaping human societies. Skills needed in adulthood are practiced in play during childhood and object play has been...

We embed observational learning (BHW) in a symmetric duopoly with random arrivals and search frictions. With fixed posted prices, a mixed-strategy pricing equilibrium exists and yields price dispersion even with ex-ante identical firms. We provide closed-form cascade bands and show wrong cascades...

"Option value" provides theoretical justification for conserving wildlife species lacking known value, but empirical assessments of actual realizations are rare. We examine quasi-option value in the context of gray wolf eradication, which aimed to protect humans and their property historically, but...

Genetically modified (GM) crops have been adopted by some of the world’s leading agricultural nations, but the full extent of their environmental impacts remains largely unknown. While concerns about the direct environmental effects of GM crops have declined, GM crops have led to indirect changes...
