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.     

Medikamente: Wohl portioniert

Patientenindividuelle Verblisterung - Eine hohe Arzneimittelsicherheit für Patienten, Bewohner und Pflegende, therapiegerecht und lückenlos dokumentiert – verblisterte Medikamente erleichtern nicht nur die Compliance und verbessern somit die Heilungschancen von Patienten. Das Pflegepersonal profitiert gleicherma?en. Denn es bleibt ihm mehr Zeit für die individuelle Betreuung der Bewohner. Das zumindest versprechen die Blisterzentren.     

The dynamics of responder behavior in ultimatum games: a meta-study

Using data aggregated from seven papers that study repeated play in standard ultimatum games with either stranger or absolute stranger matching, we show that the behavior of responders changes with experience. High offers are more likely to be accepted with experience and low offers are more likely to be rejected. At the individual level, there is a negative relationship between the likelihood that a given offer is accepted and the size of the preceding offer. We compare the results with predictions generated by static models of distributional preferences, implicitly dynamic models of preferences with reciprocity, and explicitly dynamic models of adaptive learning. The data is most consistent with models of preferences with reciprocity.     

An application of co-word analysis and bibliometric maps for detecting the most highlighting themes in the consumer behaviour research from a longitudinal perspective

This article presents an application of a bibliometric and visual study of the research carried out on a social science subfield, concretely the consumer behaviour research (CBR), from a longitudinal perspective (period 1966–2008). The study combines performance analysis and science mapping for detecting and visualizing conceptual subdomains. Quantitative and qualitative measures are used in order to identify the most prominent themes. Quantitative data are used to put together very related concepts (themes or clusters of topics), while qualitative indicators (as those based on citations) are used to measure the quality and/or impact of the detected themes. The study also uses bibliometric maps to show in a visual way the associations between the main concepts treated by the CBR community. The maps provide insight into the structure of the CBR, visualize the division of the field into several subfields, and indicate the relationships between these subfields. Co-word analysis is the bibliometric technique used to identify the main themes. All this allows us to quantify and visualize the thematic evolution of the CBR. It also helps to both experts and novices to understand the current state of the art of the CBR and to predict where future research could lead.     

Pricing multi-class network services using the Shapley Value

This paper investigates pricing issues in class-based networks. Classes of packets having lower impatience and longer average delay receive monetary compensations. The inter-class price differential is determined by the inter-class compensations. The paper also presents rules for allocating network resource to each class. The corresponding payoff (disutility share) for each class is driven by the Shapley Value of the associated cooperative game.
