Multi-trait analysis of genome-wide association summary statistics using MTAG.

Abstract: We introduce multi-trait analysis of GWAS (MTAG), a method for joint analysis of summary statistics from genome-wide association studies (GWAS) of different traits, possibly from overlapping samples. We apply MTAG to summary statistics for depressive symptoms (N eff = 354,862), neuroticism (N = 168,105), and subjective well-being (N = 388,538). As compared to the 32, 9, and 13 genome-wide significant loci identified in the single-trait GWAS (most of which are themselves novel), MTAG increases the number of associated loci to 64, 37, and 49, respectively. Moreover, association statistics from MTAG yield more informative bioinformatics analyses and increase the variance explained by polygenic scores by approximately 25%, matching theoretical expectations.

Assessing changes towards lean production

Abstract: Develops a model which operationalizes the different principles in lean production, with a focus on those that concern the work organization in the manufacturing part of a company. The model has been developed using available theory and has also been tried out in a clinical field study. The model has implications both for research and practice. For research, it can be used as a model for operationalizing lean production to be able to study change processes properly. In practice, the model can be used as a tool to assess the development taking place in an effort to become lean. Finally, it can be used as a checklist for what to aim at when trying to implement lean production. Lean should be seen as a direction, rather than as a state to be reached after a certain time and, therefore, the focus lies on the changes in the determinants, not on their actual values.

Numerical Methods for Estimation and Inference in Bayesian VAR-models

Abstract: In Bayesian analysis of vector autoregressive models, and especially in forecasting applications, the Minnesota prior of Litterman is frequently used. In many cases other prior distributions provid ...

Crowding Out in Blood Donation: Was Titmuss Right?

Abstract: In his seminal 1970 book, The Gift Relationship, Richard Titmuss argued that monetary compensation for donating blood might crowd out the supply of blood donors. To test this claim we carried out a field experiment with three different treatments. In the first treatment subjects were given the opportunity to become blood donors without any compensation. In the second treatment subjects received a payment of SEK 50 (about $7) for becoming blood donors, and in the third treatment subjects could choose between a SEK 50 payment and donating SEK 50 to charity. The results differ markedly between men and women. For men the supply of blood donors is not significantly different among the three experimental groups. For women there is a significant crowding-out effect. The supply of blood donors decreases by almost half when a monetary payment is introduced. There is also a significant effect of allowing individuals to donate the payment to charity, and this effect fully counteracts the crowding-out effect. (JEL: C93, D64, I18, Z13)
