Choosing Between Internet and Mail Survey Modes for Choice Experiment Surveys Considering Non-Market Goods 总被引:1,自引:1,他引:0
Søren Bøye Olsen 《Environmental and Resource Economics》2009,44(4):591-610
In a choice experiment setup considering a non-market good, this paper adds to the literature on survey mode effects by providing
evidence that internet surveys can be a viable alternative to traditional mail surveys when gathering feedback from a sample
of respondents. The case study concerns preferences for protecting different types of landscape from road encroachment when
building new motorways in Denmark. Two samples of respondents are surveyed—one by internet and one by mail. The performances
of the two samples are compared over six different criteria; response rates, protest responses, demographics, preferences
and WTP, estimation precision, and, finally, certainty in choice. Differences are observed for some of these criteria, implying
that analysts should be aware that choosing internet over mail could be accompanied by a survey mode effect. However, the
observed differences do not translate into significant differences in the unconditional WTP estimates. In most applied economic
valuation studies of non-market goods, the main objective is in fact estimation of WTP. Hence, in the present case, the identified
survey mode effects do not severely invalidate the applicability and continued use of the internet as a suitable means of
collecting data for choice experiment economic valuation of non-market goods. 相似文献

In this paper, we study how the intertemporal supply/demand of a security affects trading strategy. We develop a general framework for a limit order book market to capture the dynamics of supply/demand. We show that the optimal strategy to execute an order does not depend on the static properties of supply/demand such as bid–ask spread and market depth, it depends on their dynamic properties such as resilience: the speed at which supply/demand recovers to its steady state after a trade. In general, the optimal strategy is quite complex, mixing large and small trades, and can substantially lower execution cost. Large trades remove the existing liquidity to attract new liquidity, while small trades allow the trader to further absorb any incoming liquidity flow. 相似文献

Portfolio innovativeness is a central variable in innovation management. However, the impact of portfolio innovativeness on new product development (NPD) performance is unclear, which may partly be due to the construct's multifaceted nature. Different facets may reflect different degrees of innovativeness and may have different relationships with performance. In addition, firm members with different functional backgrounds may perceive and thus assess these facets differently, which again may influence the performance effect of portfolio innovativeness. Based on a sample of 746 CEOs and marketing as well as technology professionals from 117 firms and using Item Response Theory (IRT), a multifaceted scale of portfolio innovativeness, whose facets are able to cover the entire innovativeness spectrum, is developed. In addition, it is shown that the performance impact of portfolio innovativeness is dependent on the facets included in the scale, and on the specialization of the professional assessing the facets. Inverted U‐shaped performance effects are found when the scale covers the entire spectrum of innovativeness, and linear positive or zero effects with different types of more narrowly modeled scales. Inverted U‐shaped performance effects are also found when technology professionals assess the facets, while the assessments by marketing professionals lead to linear positive effects. 相似文献

In recent negotiations related to agriculture in connection with EU accession, the candidate countries asked for and received a period of 7–12 years exemption from EU rules with respect to the free movement of capital for the purpose of purchasing agricultural land. This means that, with some exceptions, foreigners will be prevented from buying land in most new member countries for a transitional period. The negotiating governments of the prospective new Member States claimed that a transitional period would be necessary because land prices are much lower in their countries than in the 15 EU ‘old’ countries. They claimed that without such an exemption, land in their countries would be bought cheaply by people of the ‘old’ EU countries, thus causing land scarcity for domestic farmers. However, statistical data do not support fears about land scarcity at present or in the future. The reasons for ‘keeping away’ foreigners from ‘national land’ are ideological rather than economic. Land continues to play a crucial role in rural-nationalist ideology, which has survived even after the disappearance of its bases, i.e. rural over-population and genuine land scarcity. 相似文献

"限塑令"作为一项制度安排,涉及多方市场主体:政府、生产者、商家及广大消费者.政府成本与社会福利的比较,决定了制度效率.在制度约束下,替代品成本的高低关系到违规的可能,而商家的竞争,使限塑面临挑战.购物袋的有偿使用,是通过抑制消费需求来控制供给,成本的转稼造成消费者剩余的损失,消费者的逆向选择行为必然与促进资源综合利用,保护生态环境的政府本意相冲突.因此,限塑作为一种制度约束,需要市场主体的共同认同,才能更好发挥作用. 相似文献

Privatised utilities are typically characterised by both undervaluation and underpricing. When faced with this problem, regulators have tended to employ a market-value approach to determine the regulatory asset base. This paper analyses this approach and shows that it magnifies the impact of any ‘short-lived’ error at privatisation and has the effect of entrenching relative errors forever. We then address the question whether there is an alternative mechanism that can accommodate the undervaluation problem but does not fall foul of the difficulties inherent in the market-value approach. The alternative we suggest is to use the regulatory agency's own estimate of the company's value, which we call the model-based asset value. It is shown that errors made at the time of privatisation do not have the same impact on future prices, and hence far less effect on the potential sale price. 相似文献

The qualitative characterisation of returns to scale in DEA has been a research issue the last decade. However, quantitative information provides the ultimate information. This paper presents two ways of obtaining numerical values of scale elasticity by an indirect approach using efficiency scores and dual variables for radial projections of inefficient points to the frontier, and a direct approach that is more general and powerful and directly evaluates numerically scale elasticity at any point on the DEA surface along intersections with planes. The direct and indirect approaches are compared using real data and a very high correspondence is found. 相似文献

Until the late 1980s, environmental regulation in Denmark was often carried out in an intensely politicized and confrontational climate marked by strong tensions between authorities and polluting firms. In recent years, however, the general spirit of regulation seems to have improved significantly. During this same period, ‘generic’ measures such as general discharge limits have been supplemented with more specific demands, tailored for individual companies. The present paper presents a case study based on the environmental regulation of TripleNine, a West Jutland fishmeal factory. In response to major changes in its market and regulatory environment, the firm has revised its general strategy and taken a more pro‐active stance on environmental issues, pursuing a policy of active co‐operation with local environmental authorities. Informed by this and other case studies, a theoretical model is developed to account for the incorporation of ecological concerns into firms' general business strategy. Against the background of this model, the paper addresses the long‐term possibilities of reconciling business strategy and public regulation in the future.

Following along the lines of a growing literature on the causal link between exporting and productivity, this paper analyzes
the existence of “learning-by-exporting” using firm-level data for Slovenian manufacturing enterprises between 1994 and 2002.
We fail to find conclusive evidence of learning-by-exporting. By matching new exporting firms to “sufficiently” similar non-exporters
and using the difference-in-differences method on the matched pairs it is revealed that productivity improvements, although
present, are far from permanent and tend to dissipate shortly after initial entry. Confronting the data on factor accumulation
with TFP measures indicates that the perceived learning effects may in fact only be a consequence of increased capacity utilization
brought about by the opening of an additional market.
