Large scale infrastructure investment and economic performance – a case study of Oresund

We analyse the effect of a large scale infrastructure investment, namely the construction of the Oresund bridge, on the local and supra-regional economy. We employ the synthetic control method to construct counterfactual regions that mimic the trajectory of Malmo and Southern Sweden without treatment. Our results point to a positive effect. However, placebo tests in space and time only reveal statistical significance at a larger regional level. The results suggest that spillover effects are eminent.     

Die Wirkung der Positionierung eines Zulieferunternehmens auf das Vertrauen des Kunden

Zusammenfassung Aus bisherigen Studien lassen sich kaum Handlungsempfehlungen ableiten, welche Positionierung eines Zulieferunternehmens sich besonders vorteilhaft auf das Vertrauen eines Kunden auswirkt. Im vorliegenden Beitrag werden die Wirkungen von vier Positionierungsstrategien, die Zulieferunternehmen zur Verfügung stehen, auf das Vertrauen ihrer Abnehmer aus der Automobilindustrie untersucht. Diese Strategien bestehen in der Anpassung an Kundenprozesse, in Serviceorientierung, in Flexibilit?t und in der Verwendung von Kompetenzsignalen gegenüber dem Markt. Wir zeigen, dass die Anpassung an Kundenprozesse auf Grund der hohen Spezifit?t der damit verbundenen Investitionen die st?rkste positive Wirkung auf das Vertrauen des Kunden aufweist und dass Kompetenzsignale gegenüber dem Markt kein geeignetes Instrument zur F?rderung des Kundenvertrauens sind, wenn das Zulieferunternehmen für den Abnehmer eine hohe Bedeutung besitzt.

The effects of a supplier’s positioning strategy on buyers’ trust

Summary Many studies have identified measures that are able to enhance partners’ trust in business-to-business relationships. However, it is not known which measures are more effective than others or under which conditions certain measures might be helpful or not. In the present study the effects of four possible positioning strategies on buyer’s trust are examined. The positioning strategies considered here are the supplier’s adaptations regarding its customer’s processes, its service orientation, its flexibility, and market-signals stressing the supplier’s competence. We found that, due to the high specificity of the required investments, adaptations of the supplier’s processes are the strongest instrument to enhance buyers’ trust relative to the other three strategies. We could also show that investments in market signals stressing the supplier’s competence are not effective if the supplier is of high importance to the customer.

     

Socially Responsible Investing and Climate Change: Contradictions and Challenges

This article explores the contradiction between the articulated investment policies, screening criteria or ethical charters of socially responsible investment funds and their actions demonstrated by their portfolio selection practice. The paper provides a background to socially responsible investment and Australia's contribution to greenhouse gas emissions. A discussion of renewable energy options lays the foundation for our main assertion: that this set of possible alternatives provides some new and more environmentally robust options that will better complement the underlying philosophy of funds in the socially responsible investment sector.     

Professionalisation or incarceration? Household engineering, accounting and the domestic ideal

Social constructionist theories of gender are utilised to explore the relationship between household accounting and patriarchy during the early twentieth century in the USA and Britain. This period witnessed a reformulation of the ideology of domesticity founded on precepts derived from modish scientific management. It is argued that the suite of calculative techniques prescribed by ‘household engineers’ merely attempted to occupy middle class women in the domestic sphere. Rather than offering a source of professionalisation and liberation, the practice of financial management, costing, record keeping and time and motion study, contributed to a reassertion of private patriarchy, confirmed the gendered nature of spatiality, reinforced the role of woman as a consumer and diverted attention from career building outside the home.     

The Returns to Education: Microeconomics

In this paper we focus on education as a private decision to invest in "human capital" and the estimation of the rate of return to that private investment. While the literature is replete with studies that estimate the rate of return using regression methods where the estimated return is obtained as the coefficient on a years of education variable in a log wage equation that contains controls for work experience and other individual characteristics, the issue is surrounded with difficulties. We outline the theoretical arguments underpinning the empirical developments and show that the evidence on private returns to the individual is compelling. Despite some of these issues surrounding the estimation of the return to schooling, our evidence, based on estimates from a variety of datasets and specifications, is that there is an unambiguously positive effect on the earnings of an individual from participation in education. Moreover, the size of the effect seems large relative to the returns on other investments.     

Economic Comparison of Alternative Tillage Systems under Risk.

Stochastic dominance efficiency criteria are used to rank the net farm return distributions for four different tillage systems under six different farm scenarios. Pairwise comparisons of tillage systems are carried over incremental upper and lower risk-aversion coefficient (RAC) bounds identified for each farm scenario, based on the size and spread of the outcome distributions to identify regions where dominance may switch between tillage systems. Ridge-till systems are generally the dominant tillage system for all farm scenarios considered. No-till systems on clay loam soils are more dominant in the risk-preferring range and less dominant in the risk-averse range, which relates to the relatively larger range of net return values and smaller mean net return values generated by this tillage system. Conversely, the moldboard plow and chisel plow systems are more dominant in risk-aversion intervals and less dominant in the risk-preferring intervals for clay loam soils. In sandy soil scenarios, the ridge-till and no-till systems are dominant over the two fall tillage systems for all farm sizes, indicating that these tillage systems are more competitive with conventional tillage systems in lighter soil type situations. A sensitivity analysis between moldboard plow and no-till systems indicates that no-till would dominate in risk-preferring intervals, and an increase in no-till net farm returns of 16 per acre would change dominance in favor of no-till in risk-averse interval space. On a utilisé les critères d'efficacitéà dominance stochastique pour classer les divers niveaux de recettes agricoles nettes dans quatre systèmes différents de travail du sol, selon six scénarios d'exploitation. Des comparaisons en paires des systèmes de travail ont été faites en regard de tranches croissantes des limites supérieures et inférieures du coefficient d'aversion du risque (CER), établies pour chaque scénario d'après l'importance et l'étendue des distributions du rendement, dans le but d'identifier les régions où la dominance serait susceptible de passer d'un système de travail à l'autre. Le système de travail sur billons était en général le système dominant dans tous les scénarios d'exploitation examinés. La culture sans travail du sol sur loam argileux était plus dominante dans les intervalles d'acceptation du resque et moins dominante dans les intervalles d'aversion du resque, cequi s'explique au fait que ce système de travail donne lieu à une fourchette relativement plus large, mais aussi à une moyenne plus faible du revenu net. À l'inverse, le labour à la charrue classique et au chisel dominait davantage dans les intervalles d'aversion du risque. Dans les sols sableux, le travail sur billons et la culture sans labour l'emportaient sur les deux autres régimes dans toutes les tailles d'exploitation, ce qui porte à croire que, dans les sols plus légers, ces régimes sont plus concurrentiels avec les systèmes classiques. L'analyse de sensibilité entre le labour à la charrue et les systèmes sans travail du sol montre que ces derniers dominent dans les intervalles d'acceptation du risque et qu'un accroissement du revenu agricole net de 16 /acre ferait glisser la dominance vers les intervalles d'aversion du risque.     

小额贷款能扫多少“钱荒”

总是有那么多诱人的概念，小额信贷的创始人尤努斯把他的发明上升到“让乞丐都能赚钱”的功能。如果说真是如此，那世界上还有穷人吗？可是，凡是存在必然有他的道理，小额信贷存在着，而且还在扩张着。按照尤努斯的说法，在小额贷款的帮助下，中小企业解决个把融资问题应该不成问题，如果乞丐都能靠此转变，那么中小企业总不会连乞丐都不如，小额信贷真的能够救赎那些缺钱缺得心慌的企业吗？     

Statistical Decision Problems and Bayesian Nonparametric Methods

This paper considers parametric statistical decision problems conducted within a Bayesian nonparametric context. Our work was motivated by the realisation that typical parametric model selection procedures are essentially incoherent. We argue that one solution to this problem is to use a flexible enough model in the first place, a model that will not be checked no matter what data arrive. Ideally, one would use a nonparametric model to describe all the uncertainty about the density function generating the data. However, parametric models are the preferred choice for many statisticians, despite the incoherence involved in model checking, incoherence that is quite often ignored for pragmatic reasons. In this paper we show how coherent parametric inference can be carried out via decision theory and Bayesian nonparametrics. None of the ingredients discussed here are new, but our main point only becomes evident when one sees all priors—even parametric ones—as measures on sets of densities as opposed to measures on finite-dimensional parameter spaces.
