Dynamic vehicle routing with anticipation in disaster relief

Pickup and delivery problems (PDP), where locations may both receive and send goods, are an extension of the classical vehicle routing problem. This paper considers the application of a routing and scheduling problem for forwarding agencies handling less-than-truckload freight in disasters. The approach evaluates the benefits of dynamic optimization anticipating varying travel times (i.e., the availability of connections in this case) as well as unknown orders (i.e., the integration of demand regions on short-notice) in the specific environment of emergencies. The objective is to avoid delays and increase equipment utilization. We model a multi-stage mixed integer problem which is able to operate under variable demand and transport conditions.     

The effect of Protestantism on education before the industrialization: Evidence from 1816 Prussia

Across Prussian counties and towns, Protestantism led to more schooling already in 1816, before the Industrial Revolution. This supports a human capital theory of Protestant economic history and rules out a Weberian explanation of Protestant education just resulting from industrialization.     

Superstars as Drivers of Organizational Identification: Empirical Findings from Professional Soccer

This paper examines the effect of superstars on external stakeholders’ organizational identification through the lens of sport. Drawing on social identity theory and the concept of organizational identification, as well as on role model theories and superstar economics, several hypotheses are developed regarding the influence of soccer stars on their fans’ degree of team identification. Using a proprietary data set that combines archival data on professional German soccer players and clubs with survey data on more than 1,400 soccer fans, this study finds evidence for a positive effect of superstar characteristics and role model perception. Moreover, it is found that players who qualify for the definition of a superstar are more important to fans of established teams than to fans of unsuccessful teams. The player's club tenure, however, seems to have no influence on fans’ team identification. It is further argued that the effect of soccer stars on their fans is comparable to that of executives on external stakeholders, and hence, the results are applied to the business domain. The results of this study contribute to existing research by extending the list of personnel‐related determinants of organizational identification.     

Nebenjob Altenhilfe

Ist die Professionalisierung am Ende? - Die Rahmenbedingungen sowie die demografische Entwicklung k?nnen dazu führen, dass das derzeitige Kompetenz- und Qualifikationsniveau des in der station?ren Altenhilfe t?tigen Personals nicht gehalten werden kann. Denn um Pflege bezahlbar zu gestalten und Personalressourcen zu erschlie?en, werden fachliche Abstriche hingenommen. Gleichzeitig verlassen f?hige Pflegekr?fte die operative Ebene der Altenhilfe. L?sst sich diese Entwicklung aufhalten?     

Compensation schemes,liquidity provision,and asset prices: an experimental analysis

In an experimental setting in which investors can entrust their money to traders, we investigate how compensation schemes affect liquidity provision and asset prices, two outcomes that are important for financial stability. Compensation schemes can drive a wedge between how investors and traders value the asset. Limited liability makes traders value the asset more than investors. To limit losses, investors should thus restrict liquidity provision to force traders to trade at a lower price. By contrast, bonus caps make traders value the asset less than investors. This should encourage liquidity provision and increase prices. In contrast to these predictions, we find that under limited liability investors increase liquidity provision and asset price bubbles are larger. Bonus caps have no clear effect on liquidity provision and they fail to tame bubbles. Overall, giving traders skin in the game fosters financial stability.     

The effect of investment in children’s education on fertility in 1816 Prussia

The interaction between investment in children’s education and parental fertility is crucial in recent theories of the transition from Malthusian stagnation to modern economic growth. This paper contributes to the literature on the child quantity–quality trade-off with new county-level evidence for Prussia in 1816, several decades before the demographic transition. We find a significant negative causal effect of education on fertility, which is robust to accounting for spatial autocorrelation. The causal effect of education is identified through exogenous variation in enrollment rates due to differences in landownership inequality. A comparison with estimates for 1849 suggests that the preference for quality relative to quantity might have increased during the first half of the nineteenth century.     

Understanding spread in the electronic futures markets: financial crisis perspective

This article analyses bid–ask spreads in U.S. electronic futures markets around the recent financial crisis. We decompose the bid–ask spread into three components – order processing, inventory holding and adverse selection costs – and show that adverse selection costs increased the most during the crisis while order processing costs are the largest cost component. Volume significantly affects inventory holding and order processing costs, whereas volatility only influences inventory holding costs. The crisis period had a significant effect on these relations. This study extends the existing literature on liquidity in equity to futures markets.     

To change or not to change–antecedents and outcomes of strategic renewal in SMEs

Companies need to constantly renew themselves to remain competitive in rapidly changing market environments, regardless of their size or age. Even though strategic renewal is a crucial factor for sustainable success of organizations, it is only an emergent area in literature. This article examines potential antecedents of strategic renewal and impact on firm performance. Based on 104 companies’ responses to a structured questionnaire, the empirical findings demonstrate that strategic renewal positively impacts firm performance, and that entrepreneurial orientation and organizational learning are antecedents. From a practical managerial viewpoint, our results suggest that firms following a strategic renewal approach can increase the long-term success of their organizations: Firms that are entrepreneurially oriented and willing to learn can successfully manage strategic renewal.     

When the difference makes a difference – the regional embeddedness of entrepreneurship

Abstract

Regional determinants of new firm formation are of interest to researchers and policymakers. In the analysis of new firm formation, most studies use econometric approaches that mask intra-unit variations, not recognizing counterbalancing and dilution effects as a result. Recent advances in spatial statistics such as Geographically Weighted Regression (GWR) take local variations into account. However, these approaches operate only on a bivariate level, making it impossible to detect the homogenous parts of the area under examination with regard to a number of relationships between new firm formation and its determinants. Based on a sample of 412 German regions, we apply GWR and subsequent graph-partitioning clustering to identify multi-relationally homogeneous sub-areas. Being that the results suggest a four-cluster solution, ‘one size fits all’ policies and premature unit zoning can be called into question.     

Generalized Pareto processes and fund liquidity risk

Motivated by the modelling of liquidity risk in fund management in a dynamic setting, we propose and investigate a class of time series models with generalized Pareto marginals: the autoregressive generalized Pareto process (ARGP), a modified ARGP and a thresholded ARGP. These models are able to capture key data features apparent in fund liquidity data and reflect the underlying phenomena via easily interpreted, low-dimensional model parameters. We establish stationarity and ergodicity, provide a link to the class of shot-noise processes, and determine the associated interarrival distributions for exceedances. Moreover, we provide estimators for all relevant model parameters and establish consistency and asymptotic normality for all estimators (except the threshold parameter, which is to be estimated in advance). Finally, we illustrate our approach using real-world fund redemption data, and we discuss the goodness-of-fit of the estimated models.
