Comparing Labor Supply Elasticities in Europe and the United States:New Results
Labor Supply Elasticities Europe United States
font style='font-size:12px;'>
2016/3/3
We suggest the first large-scale international comparison of labor supply elasticities for 17 European countries and the United States using a harmonized empirical approach. We find that own-wage elas...
How to have results from Conversations
complexity emergence strategy stucture leadership conversation
font style='font-size:12px;'>
2015/7/28
The difficulty of emergence is not the complexity but the recursivity of its working. That is why there are so many debates to know whether structure generates strategy or strategy generates structure...
Design of Search Engine Services:Channel Interdependence in Search Engine Results

Statistics turbulent coherent structures mechanical model the model of two-dimensional fluid motion
font style='font-size:12px;'>
2014/12/29
We consider a general class of statistical mechanical models of coherent structures in turbulence, which includes models of two-dimensional fluid motion, quasi-geostrophic flows, and dispersive waves....

Some results $χ$-divergence an~extended~Fisher information generalized~Cramer-Rao inequalities
font style='font-size:12px;'>
2013/6/17
We propose a modified $\chi^{\beta}$-divergence, give some of its properties, and show that this leads to the definition of a generalized Fisher information. We give generalized Cram\'er-Rao inequalit...
A statistical view on team handball results: home advantage, team fitness and prediction of match outcomes
Time series analysis of sports results statistics interdisciplinary applications of physics
font style='font-size:12px;'>
2012/9/18
We analyze the results of the German Team Handball Bundesliga for ten seasons in a model-free statistical time series approach. We will show that the home advantage is nearly negligible compared to th...
