谁来付账？

在全球，一些当前存在和正在暴露出来的问题使工业国和发展中国家同样都面临新的威胁。这些问题聚集在一起将给各国政府带来重大的社会、政冶和经济挑战，而各国政府已经被来自国际恐怖主义和其他风险的新威胁搞得神经极度紧张。这些挑战包括如下几个方面：     

Disequilibrium rational expectations: Examples of unemployment with inflation

In this paper, we present a simple dynamic general disequilibrium model which generates both unemployment and inflation as a stationary long-run equilibrium. Rational expectations (in the mean) are an essential part of this equilibrium. Policy remedies are examined. By means of an example, it is shown that rational expectations are consistent with depressed economic activity and that government policy can play an important role. It is entirely possible for inflation and unemployment to persist indefinitely.     

An exploratory study of environmental attitudes and the willingness to pay for environmental certification in Mexico

This paper explores how environmental attitudes of consumers in Mexico influence their willingness to pay a premium (or, marginal WTP) for environmentally-certified products. In addition, we also challenge the theoretical assumption that the relationship between environmental attitudes and purchasing is linear. We test our hypotheses with an analysis of marginal WTP based on a survey of 301 Mexican consumers. Using conjoint analysis to determine marginal WTP, we find support for the idea that as attitudes become more pro-environmental, they more than proportionally boost marginal WTP. We conclude our paper by discussing implications for research and practice that focus on environmental segments of consumers.     

Jumps in equilibrium prices and market microstructure noise

Asset prices observed in financial markets combine equilibrium prices and market microstructure noise. In this paper, we study how to tell apart large shifts in equilibrium prices from noise using high frequency data. We propose a new nonparametric test which allows us to asymptotically remove the noise from observable price data and to discover jumps in fundamental asset values. We provide its asymptotic distribution to decide when such jumps occur. In finite samples, our test offers reasonable power for distinguishing between noise and jumps. Empirical evidence indicates that it is necessary to incorporate the presence of jumps in equilibrium prices.     

Attitudes Towards Genetically Modified Food with a Specific Consumer Benefit in Food Allergic Consumers and Non‐food Allergic Consumers

The aim of the reported study was to investigate attitudes towards genetically modified food with a specific consumer benefit. Fifty food allergic and one hundred non‐allergic consumers took part in a telephone interview study in each of Austria, Spain and the Netherlands. Participants were first asked about their purchase intentions for an unspecified genetically modified food. Next, participants were asked about their purchase intentions for a genetically modified food with a specific consumer benefit. Food allergic consumers were asked about ‘low‐allergen food’ produced using genetic modification and non‐allergic consumers were asked about ‘food that benefits your health’ produced using genetic modification. It was found that intention to purchase genetically modified food with these specific benefits was higher than intention to purchase an unspecified genetically modified food.     

Disinvestment in health— the challenges facing general practitioner (GP) commissioners

The economic downturn is placing increasing pressure on the financing of health care. For many health care providers, this means difficult decisions need to be made over what will and will not be funded. The NHS has not typically been good at decommissioning and disinvesting in services. The recent proposed changes to the commissioning function will mean that clinicians will have a leading role in population-based priority-setting. This could well enhance the quest for legitimacy in relation to difficult resource allocation decisions. However, it is unlikely that GPs alone will be able to meet the challenges ahead, and reasonable disinvestment decisions will require GPs to engage with a number of stakeholders including government, interest groups and the wider civic society.
