This paper measures the effects of beach characteristics and hotel location with respect to the beach on sun-and-beach hotel prices by using a well-established hedonic perspective. The paper’s main results are that, after controlling for the relevant variables, location in front of a beach increases the price of a room in costal hotels of Catalonia by a figure between 13 and 17%, and that a Blue Flag increases the price by around 11.5%. The effects on hotels’ prices of other beach characteristics (such as beach length, width, sand type or beach services) are also estimated. With these estimates, the paper ranks beaches according to their characteristics and provides a setting to assess different policies regarding beaches from the point of view of hotels, such as regeneration, maintenance or achieving a Blue Flag award. 相似文献

Data Aggregation Issues for Crop Yield Risk Analysis 总被引:1,自引:0,他引:1

With increased emphasis on risk management in agriculture and a lack of disaggregated or farm‐level yield time series, decision makers are often faced with having to make adjustments to temporal yield risk measures obtained from readily available but aggregated yield data. This paper provides some empirical evidence on what type of aggregation bias to expect when measuring temporal yield risk using yield observations averaged across a region relative to yield risk estimated from quarter‐section yield time series in wheat. This study highlights some of the challenges faced when estimating aggregation distortions in measuring yield risk defined by temporal variance, especially given the nature of the empirical data set used. Cluster analysis, visual examination of relative frequency distributions and mapping of yield risk clusters suggest that using a readily available, aggregate temporal yield risk measure has the tendency to underestimate yield risk observed at the quarter‐section level and that clear, geographic yield risk boundaries do not exist in municipalities or across larger areas in this study. Further research on crops more risky than wheat appears promising. Avec un plus grand intéret sur la gestion du risk dans l'agriculture et un manque de données détaillees ou bien de collections de séries temporelles sur les rendements, les décideurs sont souvent tenus d'apporter des correctifs aux measures du risk obtenues a partir des données de rendements qui sont disponibles. Cet artcle apporte une preuve empirique du type de biais lie a l'agrégation qui peut être présent dans le calcul du risk de rendement temporel obtenu a partir de rendements moyens de blé observés au niveau régional en comparaison du risk de rendement qui est estimé a partir de données basées sur des quart‐de‐sections. Cette étude met en exergue quelques uns des obstacles qui se présentent dans l'estimation de distosions liées a l'aggrégation dans le calcul du risk de rendement défini par la variance temporelle, speciallement étant donne la charactère empirique des données utilisées. L'analyse de groupe, l'examen visual de la distribution des fréquences relatives, et la cartographie de classes de risk de rendement suggèrent que l'utilisation de la measure du risk de rendement basée sur des données disponibles de risk aggrège temporel a tendence a sousestimer le risk de rendement observe au niveau des quart‐de‐sections et qu'il n'y a pas de frontières de risk de rendement certaines, géographiques qui existent entre les municipalités ou bien a travers les zones plus larges examinées dans cette etude. 相似文献

What are the long-term effects of universal preschool programs on child outcomes? We review 26 studies using natural experiments to estimate the effects of universal preschool programs for children aged 0–6 years on child outcomes measured from third grade to adulthood. Studies comparing universal preschool with a mix of parental, family, and private modes of care show mixed effects on test scores and on measures related to health, well-being, and behavior. All estimates for outcomes related to adequate primary and secondary school progression, years of schooling, highest degree completed, employment, and earnings indicate beneficial average effects of universal preschool programs. Three of the included studies calculate benefits-to-costs ratios and find ratios clearly above one. Universal preschool tends to be more beneficial for children with low socioeconomic status and there are not consistently different effects for boys or girls. Only three studies compare two alternative types of universal preschool programs in terms of long-term outcomes. 相似文献

This paper highlights the widespread use of relational contracting in developed economies. While the number of empirical studies on relational practices in developing countries is increasing rapidly, evidence from industries and countries characterised by strong institutions is lagging behind due to data constraints. We argue that technological progress and strong institutions do not diminish the use of relational contracting, and use the US airline industry as a case in point. In particular, we discuss a number of factors (including transaction complexity, existence of collaborative relationships and data availability) that make this industry an ideal setting to study relational contracting in a developed economy. Moreover, we argue that other industries in developed countries share the properties of the US airline industry and, hence, can be used as a basis to investigate relational contracting in future work. 相似文献

This article explores which leadership qualities public managers regard as important for public innovation. It is based on a survey of 365 senior public managers in Copenhagen, Rotterdam and Barcelona. Five perspectives on leadership were identified and tested using a number of items. Some of these proved to be more robust than others. Analysis of the three cities reveals a nuanced set of leadership styles, which include a transformational style, and one that is more dedicated to motivating employees, risk-taking and including others in decision-making. This suggests the need for more research on leadership and public-sector innovation. 相似文献

This paper takes a deeper look at the measurement of the consumption-wealth ratio and analyzes its ability to capture variations in expected future stock returns. I find evidence of stock return predictability by taking a different approach than predictive regressions. 相似文献

It is usually argued that, since many of the inputs used in the production function of private firms in tourism municipalities are depletable, unsustainability looms over the horizons of tourism jurisdictions. However, this reasoning forgets that public goods are an important part of tourism products. Since public goods are nonrival (and hence nondepletable), a way out of the apparent unsustainability might exist. By considering well-established growth models, this paper argues that a correct supply of public goods may contribute to achieve sustainable development throughout time in tourism municipalities. 相似文献

The importance of concession sales in the movie exhibition industry is widely acknowledged among economists and other social
scientists that have studied this industry in the past. Despite this recognition, the lack of appropriate data has constrained
existing studies that document the role that concessions play in movie theaters. Using detailed weekly movie theater data
on concession sales, box office revenues and transaction characteristics from a major exhibitor in Spain, we shed light on
the relation between concession sales and the following factors (i) theater attendance, (ii) non-traditional channels of ticket
distribution, (iii) audience composition, and (iv) theater and market specific factors.
