Ein Tag ohne Pflege

Einen akuten und vollst?ndigen Pflegemangel haben wir in Deutschland noch nie erlebt. Das hat nur einen Grund: Beruflich Pflegende sind gepr?gt von einem hohen Ma? an ethischer Verantwortung, zu Recht liegen sie im Ranking der vertrauenswürdigen Berufe auf Platz drei. Andere Berufsgruppen zeigen eindrucksvoll, was mit Ausst?nden erreichbar ist, wenn sie nur einen empfindlichen Nerv der Bev?lkerung treffen und Mangel spürbar wird.     

School competition and students’ entrepreneurial intentions: international evidence using historical Catholic roots of private schooling

School choice research mostly focuses on academic outcomes. Policymakers increasingly view entrepreneurial traits as a non-cognitive outcome important for economic growth. We use international PISA-2006 student-level data to estimate the effect of private-school competition on students’ entrepreneurial intentions, measured by their occupational desire to manage a small enterprise. We exploit Catholic-Church resistance to state schooling in the 19th century as a natural experiment to obtain exogenous variation in current private-school shares. Our instrumental-variable results suggest that a 10%-point higher private-school share raises students’ entrepreneurial intentions by 0.3–0.5% points (11–18% of the international mean) even after controlling for current Catholic shares, students’ academic skills, and parents’ entrepreneurial occupation.     

Luther and the Girls: Religious Denomination and the Female Education Gap in Nineteenth‐century Prussia*

Martin Luther urged each town to have a girls' school so that girls would learn to read the Gospel, thereby evoking a surge of building girls' schools in Protestant areas. Using county‐ and town‐level data from the first Prussian census of 1816, we show that a larger share of Protestants decreased the gender gap in basic education. This result holds when using only the exogenous variation in Protestantism due to a county's or town's distance to Wittenberg, the birthplace of the Reformation. Similar results are found for the gender gap in literacy among the adult population in 1871.     

Numerical and analytical results for the transportation problem of Monge-Kantorovich

The Monge-Kantorovich transportation problem has a long and interesting history and has found a great variety of applications (see Rachev and Rüschendorf (1998a,b)). Some interesting characterizations of optimal solutions to the transportation problem (resp. coupling problems) have been found recently. For the squared distance and discrete distributions they relate optimal solutions to generalized Voronoi diagrams. Numerically we investigate the dependence of optimal couplings on variations of the coupling function. Numerical results confirm also a conjecture on optimal couplings in the one-dimensional case for nonconvex coupling functions. A proof of this conjecture is given under some technical conditions.

Public or Private Sector Wage Leadership? An International Perspective*

Whether a government acts as a wage leader, placing pressure on private‐sector wages (more open to competition), or whether it plays a passive role and merely follows wage negotiations in the private sector, there are important implications for macroeconomic development, particularly in small open economies and/or countries that are members of a monetary union, such as those of the European Monetary Union. With the notable exception of the case of Sweden, opinion on this issue is still divided. In this paper, we look at public‐ and private‐sector wage interactions from an international perspective (18 OECD countries). We focus on the causal two‐way relationship between public and private wage setting, confirming that the private sector, on the whole, appears to have a stronger influence on the public sector, rather than vice versa. However, we also find evidence of feedback effects from public wage setting, which affect private‐sector wages in a number of countries. When the private sector takes the lead on wages, there are few feedback effects from the public sector, while public wage leadership is typically accompanied by private‐sector feedback effects.     

Which school systems sort weaker students into smaller classes? International evidence

We examine whether the sorting of high- and low-achieving students into classes of different sizes results in a regressive or compensatory pattern of class sizes for 18 national school systems. Sorting effects are identified by subtracting the causal effect of class size on performance from their total correlation. Our empirical results reveal strongly compensatory patterns of sorting within and especially between schools in many countries. Only the United States, which has a decentralized education finance and considerable residential mobility, exhibits regressive between-school sorting. Between-school sorting is more compensatory in systems with ability tracking. Within-school sorting is more compensatory where administrators rather than teachers assign students to classrooms.     

Does Germany have competitive disadvantages vis-à-vis south-east Asia?

Résumé The German economy has no general competitive disadvantage vis-à-vis south-east Asia. Substantial disadvantages in labour-intensive industries are offset by significant advantages in human capital- and knowledge-intensive industries, in particular in mechanical engineering and road motor vehicle construction.It would be an economic policy mistake to resort to trade policy and subsidies in order to decelerate the structural change generated by import competition. On the contrary, what is required is a positive adjustment policy, which acts as a labour market cushion and helps to generate new jobs in those regions that are among the losers.     

Sovereign risk premiums in the European government bond market

This paper provides a study of bond yield differentials among EU government bonds on the basis of a unique data set of issue spreads in the US and DM (Euro) bond market between 1993 and 2009. Interest differentials between bonds issued by EU countries and Germany or the USA contain risk premiums which increase with fiscal imbalances and depend negatively on the issuer’s relative bond market size. The start of the European Monetary Union has shifted market attention to deficit and debt service payments as key measures of fiscal soundness and eliminated liquidity premiums in the euro area. With the financial crisis, the cost of loose fiscal policy has increased considerably.
