Nadelstichverletzungen: Kleiner Pieks mit großer Wirkung

Arbeitsschutz als Führungsaufgabe - Eine kurze Unachtsamkeit oder unglückliche Verkettung von Ereignissen und schon ist es passiert: Die Kanüle trifft das Pflegepersonal. Aber: Nadelstichverletzungen lassen sich durch die Verwendung sicherer Produkte und Injektionstechniken reduzieren. Dabei ist die Verbesserung des Arbeits- und Gesundheitsschutzes des medizinischen und pflegerischen Personals eine wichtige Aufgabe der Führungskr?fte.     

Dangers of commitment under rational expectations

Within a New Keynesian framework, interest rate rules that respond to public expectations lead to determinate and expectationally stable solutions for any level of commitment, as shown by Waters (Macroecon Dyn 13(4):421–449, 2009). That paper also demonstrates gains to commitment, under least square learning, though over-commitment can lead to some very poor outcomes for some parameter values. This paper shows an identical outcome under rational expectations. The optimal level of commitment is unchanged if there are observation errors in the policymaker’s knowledge of public expectations, which is not the case under learning. However, if there is sufficient policymaker uncertainty about the parameter values, partial commitment is best.     

Debt to Society: Asset Poverty and Prisoner Reentry

Every year, millions of people exit American jails and prisons and attempt to reintegrate into society. Ex-offenders face many obstacles during the transition. Scholars contend that securing employment is central to a successful transition. A job that allows an ex-offender to earn an income above the poverty line is especially significant, recent studies have shown. Consequently, many prisoner reentry initiatives are focused on expanding employment opportunities for ex-offenders. However, the almost exclusive emphasis on employment as the measurement of economic well-being is short-sighted because it ignores the importance of financial education and asset ownership. Prisoner reentry programs should include an emphasis on financial education in addition to an emphasis on employment as a means of reducing recidivism rates and improving the economic well-being of the ex-offenders and receiving communities. The paper concludes with a discussion of policy implications.     

Appropriate contract durations in the German markets for on-line reserve capacity

This paper explores the economic implications of different contract durations in markets for on-line (primary and secondary) reserve capacity in Germany with the crucial feature of separate markets for spot energy and reserve capacity provision. The analysis is based on an equilibrium model developed by Just and Weber (Energy Econo 30:3198–3221, 2008) for reserve markets. It reveals the implicit trade-off for the bidders and implicit interdependencies between the reserve and the spot markets. Even if the markets are not explicitly coordinated, they are interrelated through the dispatch decisions of the power plant owners. The paper concludes that the current German reserve market design is inefficient and should be improved. The results clearly show that shorter periods (with resulting lower variations in overall electricity demand) lead to more efficient dispatch and market results. Not only prices in the reserve capacity markets are expected to be lower, but also spot market prices. As these benefits can be partially reaped by owners of large generation portfolios also under longer contract durations, it discriminates against smaller generation companies and can potentially deter market participation. Further, the paper takes a broader perspective and discusses security concerns against shorter contract durations. It is shown that the opportunity costs character of the reserve market implies sufficient incentives for supplying online reserve capacity. The concerns do not appear to be predominant and it should be possible to manage them appropriately.     

The U.S.-China Exchange Rate Debate: Using Currency Offer Curves

The paper introduces an innovative graph for presenting bilateral exchange rates. The currency quantities are on the axes and the exchange rate is the ratio between them, i.e., the slope of a ray from the origin. Behavior is captured by currency offer curves. The paper uses the model to address the issues surrounding China’s export-led growth strategy, i.e., its policy of undervaluing the yuan.     

Temporary hires and innovative investments

The flexicurity approach claims a positive effect of flexible labour on firm performance, also through an increased ability to innovate. Critics consider it a deregulation of the labour market, decreasing investment in human capital and innovation. We contribute to this broad debate providing an estimate of the relationships linking innovative investment, substitution investment, permanent hires and temporary hires. In particular, we aim at affirming or denying that innovative investments are accompanied by a specific kind of workforce, being it stable or flexible. In doing so, we contribute to bridge the gap among two quite separate strands of literature, as existing literature usually analyses capital and labour separately. Estimating a nonlinear recursive equation system we highlight a significant increase in the likelihood of hiring on a permanent base when the firm innovates; this holds till 2008. Afterward, during the crisis, innovating firms are more likely to hire using temporary contracts instead, a possible signal of a cost saving strategy adopted in a loose labour market by firms still able to innovate. Furthermore, both permanent and temporary hires never depend on increases in labour costs; however, substitution investment increases when labour cost increases, maybe in an attempt to increase labour productivity through a more efficient capital equipment.     

Vertical Integration in the Japanese Movie Industry

This study examines vertical integration in the Japanese movie industry. I estimate an admission price equation, and a moviegoing demand equation derived from a discrete choice model of product differentiation. In order to overcome identification problems, this study exploits a panel structure dataset. My results show that the price of vertically integrated theaters tends to be higher than nonintegrated theaters, but it appears to be due to the inherent high quality of vertically integrated theaters. On the other hand, vertically integrated theaters are more popular among consumers and have higher attendance than nonintegrated theaters. Even after controlling the theater fixed effects, attendance for vertically integrated theaters is still larger than nonintegrated theaters. That is, the integration of producers/distributors and theaters is likely to be a source of economic efficiency. Policy implications are also proposed.
