In the linear instrumental variables model, we provide theoretical and Monte Carlo evidence for the size distortion of a two‐stage hypothesis test that uses a test of overidentifying restrictions (OR) in the first stage. We derive a lower bound for the asymptotic size of the two‐stage test. The lower bound is given by the asymptotic size of a test that rejects the null hypothesis when two conditions are met: the test of OR used in the first stage does not reject and the test in the second stage rejects. This lower bound can be as large as 1 ? εP, where εP is the pretest nominal size, for a parameter space that allows for local non‐exogeneity of the instruments but rules out weak instruments.

A clear understanding of residents’ attitudes towards tourism development and its determinants is a crucial pillar for designing tourism development strategies to promote sustainable development. The literature on the influence of host–tourist interactions and place attachment on residents’ attitudes towards tourism development in developing countries is still scarce. To extend knowledge in this field, this study aims at developing and testing a structural model to examine direct and indirect causal effects of place attachment, host–tourist interaction, and perceived positive and negative tourism impacts on the residents’ attitudes towards tourism development in an island tourism destination – Boa Vista Island in Cape Verde. Results suggest that the residents’ attitudes are positively affected by place attachment, host–tourist interaction, and perceived positive impacts; and negatively affected by perceived negative impacts. Host–tourist interaction emerges as the strongest (direct and indirect) determinant of the residents’ attitudes towards tourism development. Moreover, although both positive and negative perceptions of tourism impacts have significant impacts on the residents’ attitudes, the influence of the former is stronger than that of the latter. The paper ends with relevant theoretical and practical implications to promote positive residents’ attitudes towards tourism development in Boa Vista.  相似文献

Municipalities and regions are often used as an object of tourism analysis at the subnational level. This occurs because administrative borders are used to implement tourism policies and collect statistical information. However, administrative boundaries may not always be suitable for studying tourism destinations at a local level. Sometimes, particularly in high-density tourism destinations, several differentiated tourism areas occupy a single municipality; tourism areas may, and often do, extend beyond municipal boundaries and tourism destinations may not occupy the whole of the municipal area. As such, a new level of analysis is often required: the micro-destination. There are few tourism concepts as imprecise as that of the destination. Therefore, the process of identifying and establishing the boundaries of a micro-destination is by no means a straightforward one. This paper presents six criteria for establishing the boundaries of this type of tourism area. Of these six, the two primary criteria used are: the concentration of tourism establishments; and tourism typologies and supply characteristics. These criteria have been applied as part of a pilot study in the Canary Islands. Statistical information for nine micro-destinations is generated using the geolocation of tourism establishments together with information obtained from both supply-side and demand-side surveys.  相似文献

This paper analysed the validity and reliability of the revised tourist ecological orientation (RTEO) scale. There are relatively few studies in the area of the ecological behaviour of tourists and, therefore, RTEO and other scales should be taken into account in future tourism research. This study is based on a sample of 461 golf tourists. A double analysis was carried out: (1) a qualitative analysis through expert opinion and (2) a quantitative analysis through the partial least squares approach. The results suggest that the RTEO scale is a brief, simple and reliable scale of environmental actions.  相似文献

While organic food is based on well-defined production criteria, the criteria for ‘local’ food are less clear. This study investigates the preferences and trade-offs of distinct consumer segments relative to organic production and several dimensions of local food (sales channel, size of company, and geographical location of animals used in the production). The analysis is based on a quantitative survey of 505 Danish consumers and a choice experiment involving beef salami. Data were analyzed in a principal component and a latent class analysis. We identify five consumer segments whose preferences for organic and local product attributes differed substantially. Most respondents considered geographical proximity in the raising of cattle to be the most important attribute and a third of the consumers were willing to pay a premium for organic salami. The segmentation provides more detailed information about stated consumer behavior than what is typically elicited when considering only average consumer behavior.  相似文献

Since voters are often swayed more by the personal image of politicians than by party manifestos, they may cast votes that are in opposition to their policy preferences. This results in the election of representatives who do not correspond exactly to the voters’ own views. An alternative voting procedure to avoid this type of election failure is prompted by the approach implemented in internet voting advice applications, like the German Wahl-O-Mat, which asks the user a number of questions on topical policy issues; the computer program, drawing on all the parties’ answers, finds for the user the best-matching party, the second-best-matching party, etc. Under the proposed alternative election method, the voters cast no direct votes. Rather, they are asked about their preferences on the policy issues as declared in the party manifestos (Introduce nationwide minimum wage? Yes/No; Introduce a speed limit on the motorways? Yes/No, etc.), which reveals the balance of public opinion on each issue. These embedded referenda measure the degree to which the parties’ policies match the preferences of the electorate. The parliament seats are then distributed among the parties in proportion to their indices of popularity (the average percentage of the population represented on all the issues) and universality (frequency in representing a majority). This paper reports on an experimental application of this method during the election of the Karlsruhe Institute of Technology Student Parliament on July 4–8, 2016. The experiment shows that the alternative election method can increase the representativeness of the Student Parliament. We also discuss some traits and bottlenecks of the method that should be taken into account when preparing elections.  相似文献

Recent legislation and court settlements in the United States allow merchants to use price discounts to steer customers to pay with means of payment that are less costly to merchants. We use transaction data to compute rough estimates of the expected net cost reduction by merchant type of giving debit card and cash price discounts. We find that steering consumers to debit and cash via simple price discounts reduces most merchants’ card processing cost; however, this reduction is small and may be insufficient to offset the increase in the cost of administering price menus that vary by payment instrument.  相似文献
