One rationale for devolution is that local decision makers may be well placed to adapt national policies to the local context. We test whether such adaptation helps meet programme objectives in the case of the Apprenticeship Grant for Employers. Originally a national programme, aimed at incentivising employers to take on apprentices, reforms a few years into operation gave some Local Authorities negotiated flexibilities in how the scheme operated. We consider the impact of the national scheme and then use a difference-in-differences approach to test whether flexibility led to an increase in the number of apprenticeship starts in devolved areas relative to control groups. We find that flexibility had zero effect. There is suggestive evidence that this is because flexibilities were negotiated on the wrong margins.  相似文献

世界资本主义目前正接受着气候变化的挑战,这主要是由与矿石燃料消耗相关的温室气体的排放造成的。为了预防这一灾难性环境后果威胁到人类的生存,在资本主义内部必须对经济增长做出根本性和即时性承诺。从对在世界经济中中国和印度的崛起与气候危机之间的相互关系分析表明,要达到减排目标几乎需要实现经济零增长,以减轻气候危机。在大量使用矿石燃料基础上的传统发展模式不再适用,中国和印度需要更改它们的发展模式。只有一种重在社会和环境进步,而不是经济增长的新型发展战略,才可以为人类未来带来更多的福祉。  相似文献

One day while in the store, Bernard grabs his usual Dominick's cream cheese off the shelf. I notice and point out that the national brand of Philadelphia cream cheese is on sale and less expensive. Bernard looks at the two products and actually hesitates for a while to switch to the national brand. His hesitation makes it clear that his preference is not based solely on price.

We consider the supplier’s strategic choice on delivery time in a public procurement setting as the result of the firm’s opportunistic behavior on the optimal investment timing when production costs are uncertain. We model the supplier’s trade-off between the option value to defer the contract execution and the penalty payment in the event of delays. We also take into account the issue of penalty enforcement, which in turn depends on both the discretion of the court of law in voiding contractual clauses and the “efficiency” of the judicial system (i.e. the average length of civil trials). We test our main results on Italian public procurement data showing that the supplier’s incentive to delay is greater the higher the volatility of production costs and the lower the “efficiency” of the judicial system. We then calibrate the model using parameters that mimic the Italian scenario on public works procurement and calculate the maximum amount that a supplier is “willing to pay” (per day) to postpone the delivery date and infringe the contract provisions. Our calibration results are consistent with the theoretical model’s predictions and the empirical findings.  相似文献

In recent years, growing attention has been devoted to the commercialisation of knowledge and technologies developed by universities and public research institutions. A central role in this particular process is played by the technology transfer offices (TTOs), which are on the one hand in charge of promoting the transfer of knowledge and technology to external companies, and on the other hand are also responsible for protecting and licensing the intellectual property of the research organisation. This paper is focused on a TTO operating in the food context, with the specific objectives of identifying the performance indicators and the main factors affecting its performance and, finally, analysing the relationships among these factors. Results highlighted the importance of both external and internal factors for the performance of a TTO operating in this context. In addition, we found both direct and indirect relations within these factors.  相似文献

We study coalitional economies under uncertainty and asymmetric information, assuming a finitely additive measure space of agents and finitely many possible states of nature. We introduce a suitable core notion showing that it is equivalent to Walrasian expectations equilibria. The finitely additive approach proposed in the paper permits also asymmetric information economy with countably many agents, rather than requiring only a continuum. Moreover, it allows us to overcome well-known criticisms related to the interpretation of individual private core notions.  相似文献

Hydrogen can be viewed as the flexible automotive fuel of the future. However, many issues related to its use have not been sufficiently investigated. One such issue concerns hydrogen logistics and distribution throughout a territory. One near-term scenario over the next decade is likely to include distribution procedures that are similar to those currently used for petrol products. In this scenario, the conversion of petrol service stations into hydrogen distribution points will progressively be implemented. Petrol companies will then represent one of the major categories of hydrogen producers. They will thus have to select, from a cost/benefit standpoint that accounts for competing companies expected to offer the same service throughout a territory, the most convenient and effective locations for hydrogen distribution. The current paper presents a model for planning a network of service stations of a given company within a competitive framework. A case study of a specific territory in northern Italy is presented and discussed.  相似文献

Determinants of the Euro Real Effective Exchange Rate: A BEER/PEER Approach   总被引:3,自引:0,他引:3  
This paper presents an empirical analysis of the medium–term determinants of the euro effective exchange rate. The empirical analysis builds on synthetic quarterly data from 1975 to 1998, and derives a Behavioural Equilibrium Exchange Rate (BEER) and a Permanent Equilibrium Exchange Rate (PEER). Four different specifications are retained, due to the difficulties encountered in specifying an encompassing model. The results indicate that differentials in real interest rates and productivity, and (in some specifications) the relative fiscal stance and the real price of oil, have a significant influence on the euro effective exchange rate. Assessing the existence and the extent of the over– or undervaluation of the exchange rate is not straightforward, since these different specifications often lead to contrasting findings. However, all four specifications point unambiguously to the undervaluation of the euro in 2000, although the extent of this undervaluation largely depends on the specification chosen.  相似文献
