We apply ideas put forward in the literature on the international coordination of macroeconomic and trade policies to study the merits of an international coordination of antidoping policies. Without international coordination of antidoping policies, sports associations and national anti-doping...

Abstract Economists use three types of models to describe volunteer labour supply: the public-goods model, the private-consumption model, and the human-capital model. We used data from an online survey questionnaire of volunteers working for the German Red Cross to study the extent to which...

Economic theory predicts that, in a small open economy, the dynamics of the real price of gold should be linked to real interest rates and the rate of change of the real exchange rate. Using data for Australia, we use a real-time forecasting approach to analyze whether real interest rates and...

Economists use three types of models to describe volunteer labour supply: the publicgoods model, the private-consumption model, and the human-capital model. We used data from an online survey questionnaire of volunteers working for the German Red Cross to study the extent to which each type...

We used boosted regression trees to study the interplay between match quality and Internet use of volunteers. In our use of the term, match quality reflects the congruence of volunteers' motives for doing volunteer work and their utility experiences. Using data from an online survey...

Using data for a large sample of German football referees, we studied the motives for becoming a football referee. Based on a long modeling tradition in the literature on the economics of volunteering, we studied altruistic motives (public-goods model) versus non-altruistic (egoistic...

Against the background that the number of referees has been falling in recent years, the German Football Association (DFB) needs to answer two key questions: (i) Why do referees end their careers, and, (ii) which factors determine the duration of referee careers? We studied these questions using...

Volunteering can be interpreted as a process of search that matches volunteer labor supply with demand for volunteer work by voluntary organizations like sports clubs. Using novel data from an online questionnaire study of German sports club members, we constructed a match quality index (MQI)...

Research question: We uncover the influence of performance parameters on market value of football players in German Bundesliga. Hereby, the analyses should in some places reach beyond the current state of research by, for example, using relative operating times or running kilometres in the...
