This paper proposes a way of using observational pretest data for the design of experiments. In particular, this paper trains a random forest on the pretest data and stratifies the allocation of treatments to experimental units on the predicted dependent variables. This approach reduces much of...

This study derives an optimal pairs trading strategy based on a Lévy-driven Ornstein-Uhlenbeck process and applies it to high-frequency data of the S&P 500 constituents from1998 to 2015. Our model provides optimal entry and exit signals by maximizing the expected return expressed in terms of...

Between 1990 and 2008, many industrializing countries have experienced tremendous economic growth, which coincided with a substantial increase in the use of materials. That poses the question how a continued economic convergence of developing nations will affect the use of biomass, fossil fuels,...

With his announcement to pull the US out of the Paris Agreement US President Donald Trump has snubbed the international climate policy community. Key remaining parties to the Agreement such as Europe and China might call for carbon tariffs on US imports as sanctioning instrument to coerce US...

Immigration is a crucial issue in contemporary politics, and attitudes towards immigration are highly dispersed in many countries. We treat individuals' immigration friendliness (IF) as a feature of their self-image or identity and hypothesize that, similar to other pro-social self-images,...

This paper hypothesizes and empirically establishes the persistent effects of novelty-seeking traits on crosscountry differences in scientifc knowledge creation. I use data on the prevalence of specifc allele variants of the human DRD4 exon III gene, which population geneticists have linked to...

In spite of scientific agreement on the negative effects of anthropogenic climate change, efforts to find cooperative solutions on the international level have been unsatisfactory so far. Trade sanctions in the form of import tariffs are one principal measure discussed as a means to foster...

Recent literature has found that individuals holding a greener self-image display higher levels of life satisfaction. We extend the single-country setting of that research to a transnational perspective and explore whether a relationship exists between green self-image (GSI) and life...

Recent experimental studies analyze the behavior of physicians towards patients and find that physicians care for their own profit as well as patient benefit. In this paper, we extend the experimental analysis of the physician decision problem by adding a third party representing the health...

This paper develops a statistical arbitrage strategy based on overnight social media data and applies it to high-frequency data of the S&P 500 constituents from January 2014 to December 2015. The established trading framework predicts future financial markets using Factorization Machines, which...
