Performance pay and productivity of low- and high-ability workers

Existing literature has mainly focused on analyses of the overall effect of a change in the incentive scheme. Lazear (Lazear, E., 2000, “Performance pay and productivity”, American Economic Review, 90, 1346–1361.), for example, estimates the average increase in productivity after a firm switches from an hourly-wage scheme to a piece-rate plus basic-wage scheme. His paper does not, however, account for the fact that many workers remained within the basic-wage range after the change was made in the incentive scheme. In the present paper we explore how the incentive effect might have been different for those workers seeking the basic wage, and those workers seeking the piece-rate component of the wage. Interestingly, the change in productivity is approximately the same in percentage terms for both types of workers.     

INCORPORATING RISK AND AMBIGUITY AVERSION INTO A HYBRID MODEL OF DEFAULT

It is well known that purely structural models of default cannot explain short‐term credit spreads, while purely intensity‐based models lead to completely unpredictable default events. Here we introduce a hybrid model of default, in which a firm enters a “distressed” state once its nontradable credit worthiness index hits a critical level. The distressed firm then defaults upon the next arrival of a Poisson process. To value defaultable bonds and credit default swaps (CDSs), we introduce the concept of robust indifference pricing. This paradigm incorporates both risk aversion and model uncertainty. In robust indifference pricing, the optimization problem is modified to include optimizing over a set of candidate measures, in addition to optimizing over trading strategies, subject to a measure dependent penalty. Using our model and valuation framework, we derive analytical solutions for bond yields and CDS spreads, and find that while ambiguity aversion plays a similar role to risk aversion, it also has distinct effects. In particular, ambiguity aversion allows for significant short‐term spreads.     

Rationality in supplier selection decisions: The effect of the buyer's national task environment

Our study sheds light on two fundamental questions in supply management: First, does adherence to highly rational decision processes help buyers make better supplier selection decisions? Second, is the influence of procedural rationality on decision effectiveness moderated by buyers’ (differently dynamic) task environments? We empirically test these questions using a sample of 150 supplier selection decisions taken in China and 150 decisions taken in Germany, countries that expose buyers to dynamic decision environments and stable decision environments, respectively. Our findings suggest that the influence of decision process rationality is stable across decision makers’ task environments. Both in China and in Germany, such process rationality is positively related with higher decision quality, and no significant differences in relationship strengths emerge between the two country samples.     

Property rights for the poor: Effects of land titling

Secure property rights are considered a key determinant of economic development. The evaluation of the causal effects of property rights, however, is a difficult task as their allocation is typically endogenous. To overcome this identification problem, we exploit a natural experiment in the allocation of land titles. In 1981, squatters occupied a piece of land in a poor suburban area of Buenos Aires. In 1984, a law was passed expropriating the former owners' land to entitle the occupants. Some original owners accepted the government compensation, while others disputed the compensation payment in the slow Argentine courts. These different decisions by the former owners generated an exogenous allocation of property rights across squatters. Using data from two surveys performed in 2003 and 2007, we find that entitled families substantially increased housing investment, reduced household size, and enhanced the education of their children relative to the control group. These effects, however, did not take place through improvements in access to credit. Our results suggest that land titling can be an important tool for poverty reduction, albeit not through the shortcut of credit access, but through the slow channel of increased physical and human capital investment, which should help to reduce poverty in future generations.     

CREDIT DEFAULT SWAPS – WEAPON OF MASS DESTRUCTION OR RELIABLE INDICATOR?

Credit Default Swaps (CDS) are said to increase systemic vulnerability, but they also serve as an ex‐ante indicator of default probabilities, more finely‐tuned and more responsive than ratings agency reports. And they provide a useful mechanism for trading risk and an incentive for good management by businesses and governments.     

Behaviour theory and soft transport policy measures

The aim is to propose a theoretical grounding of soft transport policy measures that aim at promoting voluntary reduction of car use. A general conceptual framework is first presented to clarify how hard and soft transport policy measures impact on car-use reduction. Two different behavioural theories that have been used to account for car use and car-use reduction are then integrated in a self-regulation theory that identifies four stages of the process of voluntarily changing car use: setting a car-use reduction goal, forming a plan for achieving the goal, initiating and executing the plan, and evaluating the outcome of the plan execution. A number of techniques are described that facilitate the different stages of the process of voluntary car-use reduction and which should be used in personalized travel planning programs.     

Die Prognose von Serviceintervallen mit?der?Hazard-Raten-Analyse – Ergebnisse einer empirischen Studie im Automobilmarkt

Mit dem After Sales-Gesch?ft generieren die deutschen Automobilbauer etwa die H?lfte ihrer Gewinne. Gerade vor dem Hintergrund der aktuellen gesamtwirtschaftlichen Entwicklungen, wovon insbesondere das Neuwagengesch?ft betroffen ist, erscheinen Anstrengungen zur Optimierung der kundenindividuellen Ansprache im Service-, Teile- und Wartungsgesch?ft aussichtsreich zu sein. Als Voraussetzung dafür kann das Wissen über die kundenindividuellen Serviceintervalle als entscheidender Wettbewerbsvorteil gesehen werden, denn nur hiermit lassen sich Kunden auch zielgerichtet ansprechen und potenzielle Abwanderungen vermeiden. Genau an diesem Punkt knüpft dieser Beitrag an, indem mit der Hazard-Raten-Analyse ein wissenschaftlich fundiertes und praktikables Verfahren zur Prognose kundenindividueller Serviceintervalle illustriert wird. Da dieses im betriebswirtschaftlichen Kontext ohnehin sehr junge Analyseverfahren bislang überwiegend im FMCG (Fast Moving Consumer Goods)-Bereich auf Scannerdaten zum Einsatz kam, kann dieser Beitrag als Leitfaden für eine Erweiterung im Bereich langlebiger Konsum- und Investitionsgüter gesehen werden. Die Ergebnisse zeigen, dass der Anteil korrekt gesch?tzter Serviceintervalle die einfache lineare Fortschreibung, die bis dato das Standardverfahren zur Prognose von Serviceintervallen darstellt, um über 20% übertrifft bzw. die Prognosegenauigkeit von ±73 Tagen auf ±38 Tage gesteigert werden kann. Das Erfolgspotenzial einer kundenindividuellen Direktansprache l?sst sich mit dieser substanziellen Verbesserung der zugrunde liegenden Informationsbasis erheblich steigern. Aus der Verbesserung der Prognosegenauigkeit auf kundenindividueller Ebene (Mikroebene) resultiert schlie?lich auch auf der Makroebene (Unternehmensplanung- und steuerung) eine erh?hte Planungssicherheit.     

Web Services for Negotiation and Bargaining in Electronic Markets: Design Requirements, Proof-of-Concepts, and Potential Applications to e-Procurement

Information Systems researchers continue to develop Web services hoping that, in a near future, these services will be widely offered in the e-marketplace, using a Web-based protocol that is universally adopted for posting, locating and invoking available services. Posting services does not, however, necessarily lead to market transactions, and a number of brokering activities are needed to facilitate trade. These include, but are not limited to, service discovery and ranking, price negotiation and contract preparation. We propose a set of Web services that support the process of negotiation and bargaining to facilitate the matching of supply and demand of Web services. As a market broker, these web services would help (a) discover the supply/demand of web services in e-marketplaces; (b) find the most appropriate available service for a specific request; (c) facilitate services be modified if needed to satisfy user's needs; (d) arbitrate the pricing mechanism with the recourse to bargaining whenever necessary; and (e) generate a contract. As a proof of concept, we illustrate the potential use of Web services for negotiation and bargaining in e-procurement.
