What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0–6 years on child outcomes measured from third grade to adulthood. Studies comparing universal preschool with a mix of parental, family, and private modes of care show mixed effects on test scores and on measures related to health, well-being, and behavior. All estimates for outcomes related to adequate primary and secondary school progression, years of schooling, highest degree completed, employment, and earnings indicate beneficial average effects of universal preschool programs. Three of the included studies calculate benefits-to-costs ratios and find ratios clearly above one. Universal preschool tends to be more beneficial for children with low socioeconomic status and there are not consistently different effects for boys or girls. Only three studies compare two alternative types of universal preschool programs in terms of long-term outcomes.  相似文献

Climate change poses significant new risks and challenges for businesses and their supply chains. Additionally, in many sectors, Scope 3 indirect greenhouse gas emissions resulting from the sourcing and distribution of goods and services are larger than firms' own carbon footprints. Here we study how firms engage their key stakeholders in their supply chains in obtaining, processing, and transferring relevant climate change‐related information designed to overcome information asymmetry and drive sustainable development. Grounded in organisational information‐processing theory (OIPT), we draw on data from the Carbon Disclosure Project's Climate Change Supply Chain initiative for a qualitative content analysis of a large sample of global firms. Consistent with OIPT, we find that although firms primarily engage their supply chain partners in a variety of ways to reduce information uncertainty around indirect emissions data, effectively interpreting and managing broader sustainability information equivocality becomes a growing priority. Our findings further suggest that firms engage suppliers, customers, and other supply chain partners through basic, transactional, and collaborative types of engagement. We contribute to literatures on interorganisational information processing and sustainable supply chain management by providing a more detailed understanding of how firms engage supply chain partners in the context of climate change.  相似文献

We present and discuss measures for analyzing productivity in deterministic frontier models. A new efficiency measure is introduced allowing for discrimination among efficient organizational units. In addition, a new performance measure for analyzing productivity of organizational units is presented. This measure fulfills various properties of efficiency measures but relaxes the indicator property. Both new approaches are based on the development of efficiency vectors which is a new vector measure for measuring efficiency. The vector components are efficiency measures related to subsets of a production possibility set. The new approaches are applied in the context of data envelopment analysis.

In conjunction with the rapidly advancing industrialization of Turkey, the segment of industrial insurance has also steadily gained in importance. People seeking cover for industrial risks situated in Turkey, however, face several rather significant constrictions. Whilst some of those may be circumvented at least partially, the Turkish situation raises the question of the need for legislative reform (possibly inspired by German law) in this area. Such would foster the development of more innovative and adequate insurance products by the Turkish insurance market.  相似文献

The demographic change and its consequences forces citizens of Germany to realign towards private insurance products. This decision should be based on structured analyses. Most recent studies were inconclusive regarding this decision.As investments are commonly compared using average developments of the underlying, the possibility to switch the underlying during the duration of the investment, they are not represented accordingly and therefore bias the results of the calculation. We perform a thorough simulation analysis to compare two competing investments for retirement provisions while respecting additional costs and tax implications of switching.Without any switching the evaluation of other studies is generally verified (pure investment beats insurance product). But as soon as switching is implemented the tax advantage of insurance products is overcompensating the cost advantage of a pure investment solution. Further research should aim in this direction.  相似文献

The banking industry has one of the most active markets for mergers and acquisitions. However, little is known about the type of operational strategies adopted by banking firms in the years following a deal. For a sample of bidding banks in the USA and Europe, this study compares the design and performance implications of different post‐merger strategies in both geographical regions. Using accounting data, we show that European banks pursue a cost‐cutting strategy by increasing efficiency levels vis‐à‐vis non‐merging banks and by cutting back on both labour costs and lending activities. US banks, on the other hand, raise both interest and non‐interest income in the post‐merger period.  相似文献

In the midst of the EU’s current “polycrisis “, several serious dangers threaten the future of Europe’s unity. The looming Brexit vote as well as the refugee crisis and–above all–the rise of nationalistic, right-wing extremist parties demonstrate the fragility of the EU. One of the EU’s fundamental problems is its institutional design in general. In particular the role of the European Central Bank is not fit for the challenges of the time. Moreover, the EU is facing disintegrative pressures while simultaneously pursuing moves towards deepening the Union as a reaction to the multiple crises. Against this background, it is highly likely that differentiation within the EU will increase. Deeper cooperation among small groups of member states will likely increase efficiency but may also reduce transparency, accountability and cohesion within the EU. If handled well, differentiation may also open new pathways for cooperation with the EU’s neighbours and accession countries. The foundation for a fresh start in Europe is the Franco-German relationship, as only these two Member States together can prevent Euroscepticism from spreading even further and the new radical right from taking control of Europe.  相似文献

This paper takes as its starting point the fact that complex projects, interpreted as multiple dependent interactions between many stakeholders over time, challenge traditional procurement practices based on the serial purchase of discrete components. The paper examines how the procurement management of such projects – procuring complex performance – can be conducted. The paper utilises two contrasting case study examples of high-profile UK construction project procurement. The findings suggest that the choice of mechanisms or interfaces for the governance of upstream supply relationships critically relates to subsequent performance. The theoretical contribution is a fusion of procurement literature with the influential CoPS literature.  相似文献
