This paper discusses the use of forced restriction of food choice as an instrument of food policy by using the mandatory Helsinki School District weekly vegetarian day as a natural experiment. Overall, the results show that the initiative produced a mixture of intended and unintended effects. On vegetarian days, there were clear signs of non-compliance in the short term, manifested as a decrease in the participation in school lunches and in the amount of food taken to the plate and as an increase in plate waste. In the medium term, the only sign of non-compliance was a decrease in the amount of food taken to the plate. The difference between the short- and medium-term effects can be interpreted as a weakening of non-compliance, as a change in the way it manifested itself, or a combination of both. The effects of the vegetarian day differed between school levels. In the short term, the clearest indications of non-compliance were found in lower-secondary schools. However, these schools also registered positive spillover effects in the medium term. The best way to reduce the unintended effects of a policy involving forced choice restriction depends on the causes of such effects. In the case of psychological reactance, default options may be preferable to forced choice restriction. For hedonic dislike, menu development should be prioritized, and moral suasion and information campaigns may help where non-compliance stems from a disagreement with the objectives and effectiveness of the intervention. Thus, forced choice restriction should be accompanied by detailed data collection to understand the possible causes of intended and unintended effects and to tailor the intervention to the target group.  相似文献

Using firm‐level data on the Italian manufacturing industry, we examine how trade activities are related to workforce composition and wages. We contribute to empirical research on these issues in three ways. First, we provide new evidence that is consistent with multi‐attribute models on firm heterogeneity and trade. We show that even after controlling for various company characteristics, including size and capital intensity, exporters still pay higher wages and employ more skilled workers than nonexporters. Second, we consider engagement in international transactions, either by means of exports, imports, or a combination of the two. We show that failing to control for importing activities may bias upward export premia. Third, we look at how the wage and the employment structures of trading firms change with the country of destination and origin of trade flows. We find that wage and skill premia are influenced by the characteristics of partner countries.  相似文献

This paper describes a scale, called SERVQUAL, which measures Service Quality. First, the scale's conceptual framework and the steps of its development are described. Second, criticisms arising from several replication studies of SERVQUAL are reviewed. The last part focuses on the dimensionality of the scale. Do the 22 items of the SERVQUAL scale clearly evoke, in the clients’ mind, the five Service Quality dimensions defined by Parasuraman et al. [1988]? An empirical study shows that one dimension, ‘Tangibles’, is clearly perceived followed by ‘Empathy’. The three other dimensions, ‘Reliability’, ‘Insurance’ and ‘Responsiveness ', are confused in the client's mind.  相似文献

Elaborating on the notions that humans possess different modalities of decision-making and that these are often influenced by moral considerations, we conducted an experimental investigation of the Trolley Problem. We presented the participants with two standard scenarios (‹lever’ and ‹stranger’) either in the usual or in reversed order. We observe that responses to the lever scenario, which result from (moral) reasoning, are affected by our manipulation; whereas responses to the stranger scenario, triggered by moral emotions, are unaffected. Furthermore, when asked to express general moral opinions on the themes of the Trolley Problem, about half of the participants reveal some inconsistency with the responses they had previously given.  相似文献

The 2008/09 economic crisis has been the worst crisis of capitalism since the Great Depression. The causes and implications of the so-called “Great Recession” have been widely documented, but the effects of the crisis on psychological well-being have only received limited attention. Using state-level data, this paper aims to assess empirically the impact of the 2008/09 crisis on several indicators of mental health in the USA. The results indicate that unemployment and income levels have a significant and detrimental impact on mental health. This implies that social protection systems—and in particular labor market programs—play a paramount role in reducing the adverse impact of the crisis on mental health.  相似文献

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

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
