The communication that Destination Management Organizations (DMOs) address to destination stakeholders plays a central role in attracting attention and resources for sustainable destination development and disclosing the efforts made to be a sustainable territory. There has been extensive analysis on the role of official tourism websites that addresses both DMO's internal and external stakeholders. However, less exploration is available on the relationship between the contents disclosed through tourism websites and the strategic positioning of the destination. This study empirically examines that link with a focus on ‘green/sustainable/responsible' travel. Results show a positive association between the orientation to sustainability in online communication and both sustainable regulation of the tourism sector and tourism development. In contrast, there is no significant association with destination size, tourism maturity and pricing policies.  相似文献

This paper studies the political economy of pricing and investment for excludable and congestible public goods in a federal state. Although the model applies to many local congestible public facilities (such as libraries, museums and public swimming facilities), our main motivation is the problem of providing and pricing road infrastructure in federal states. The two-region model we develop allows for spill-overs between regions, it takes into account congestion, and it captures demand heterogeneity both between and within regions. Regional decisions are taken by majority voting; federal decisions are taken by a minimum winning coalition in a legislature of regionally elected representatives. We have the following results. First, when users form the majority in at least one region, decentralized decision making performs certainly better than centralized decision making if spill-overs are not too large. Centralized decisions may yield higher welfare than decentralization only if users have a large majority and the infrastructure in a given region is intensively used by both local and outside users. Second, if non-users form a majority in both regions, centralized decision making and decentralized decision making yield the same socially undesirable outcome, with prices that are much too high. Third, the performance of decentralized supply is strongly enhanced by local self-financing rules; this prevents potential exploitation of users within regions.  相似文献

Drawing on the structurationist notion of ‘technologies-in-practice’, this article analyses the different types of technological actions that users perform, after technological change, in order to keep a declining technology alive over time. The research question of the article is: How do technologies-in-practice based on the application of new technology hamper the creative destruction of old technology? The case study of ham radio technology and amateur radio operators is explored. The results of the investigation support the development of a technology-in-practice ‘experimentation’ and four inductive research propositions.  相似文献

Social cooperatives represent the most notable form of non‐profit organizations operating in Italy in the social services field, the birth and development of which has been strongly linked to, and conditioned by, the needs and resources of territories and communities. This paper intends to demonstrate how certain socio‐economic factors, recognized in economic literature as antecedents of the development of social enterprises, may account for the spread of social cooperatives in different Italian regions. Furthermore, the research results demonstrate an inter‐regional differentiation of the shape social cooperation has entered into in Italy.  相似文献

We develop an agency model of organized crime accounting for the main trade‐offs involved in the introduction of an accomplice‐witness program. We characterize the optimal policy and identify its main determinants in a framework where public officials can be dishonest. Our predictions are tested by using data for Italy before and after the introduction of the 1991 accomplice‐witness program. As predicted by the model and the earlier antitrust literature, the program appears to have strengthened deterrence and enhanced prosecution. Moreover, consistent with a novel prediction of our theory, the evidence suggests that the program efficacy is affected by the judicial system efficiency.  相似文献

International emission trading is an important flexibility mechanism, but its use has been often restricted on the ground that access to international carbon credits can undermine the domestic abatement effort reducing the incentive to innovate and, eventually, lowering the pace of climate policy-induced technological change. This paper examines the economics that is behind these concerns by studying how a cap to the trade of carbon offsets influences innovation, technological change, and welfare. By using a standard game of abatement and R&D, we investigate the main mechanisms that shape these relationships. We also use a numerical integrated assessment model that features environmental and technology externalities to quantify how limits to the volume, the timing, and the regional allocation of carbon offsets affect climate policy costs and the incentive to invest in innovation and low-carbon technologies.Results indicate that, for moderate caps on the amount tradable emissions permits and sufficiently high technology spillovers, global innovation and technical change would increase and that this additional innovative effort could lead to economic efficiency gains. The numerical analysis confirms that when constraints are close to 15% of domestic abatement, efficiency losses are small because they are partly compensated by more technological spillovers and lower energy prices. Under a broad range of parameters, restrictions are costly for the constrained countries, but always beneficial for unconstrained ones.  相似文献

《联合国反腐败公约》对洗钱犯罪作了规定,我国现行《刑法》对洗钱罪的规定与《公约》存在较大差异,从而使我国对洗钱罪及其上游犯罪的预防和打击的效果受到影响。我们有必要根据《公约》的规定完善我国关于洗钱犯罪的立法。  相似文献

Booms and busts in housing markets: Determinants and implications   总被引:2,自引:0,他引:2  
This study looks at the characteristics and determinants of booms and busts in housing prices for a sample of eighteen industrialised countries over the period 1980–2007. From an historical perspective, we find that recent housing booms have been amongst the longest in the past four decades. Estimates of a Multinomial Probit model suggest that domestic credit and interest rates have a significant influence on the probability of booms and busts occurring. Moreover, international liquidity plays a significant role for the occurrence of housing booms and—in conjunction with banking crises—for busts. We also find that the deregulation of financial markets has strongly magnified the impact of the domestic financial sector on the occurrence of booms.  相似文献
