Modeling Airbnb demand to New York City while employing spatial panel data at the listing level

Using spatial panel data comprising a cross section of 1,461 continuously active Airbnb listings obtained from AirDNA, as well as time series data from NYC and Company and the OECD covering the time period September 2014 to June 2016, the present study quantifies own price, cross price, and income elasticities of Airbnb demand to New York City within an empirical tourism demand framework. The particular goal of the study is to establish whether the relationship between Airbnb and the traditional accommodation industry is of a substitutional or of a complementary nature. Employing a one-way fixed-effects spatial Durbin model, it can be concluded that demand is price-inelastic for Airbnb accommodation in New York City, which is a luxury good, and that the city's traditional accommodation industry as well as neighboring Airbnb listings are substitutes for the investigated Airbnb listings. The estimation results are robust against several alternative specifications of the regression equation.     

Cultural Consonance in Leisure,Leisure Satisfaction,Life Satisfaction,and Self-Rated Health in Urban Taiwan

The purpose of this study threefold: to determine whether a shared cultural model of the importance of a set of leisure activities to a good leisure life existed in urban Taiwan, the degree to which cultural consonance in leisure mediates the relationship between leisure constraints and leisure satisfaction, and the degree to which leisure satisfaction affects life satisfaction and self-rated health. Results indicate that a cultural model of the importance of leisure activities to a good leisure life existed among sample members. Second, higher levels of self-reported participation in leisure activities that are culturally agreed upon as more important for a good leisure life are more strongly associated with leisure satisfaction than are activities culturally agreed upon as less important. Finally, leisure satisfaction strongly predicts both life satisfaction and self-rated health.     

Empowerment and resident support for tourism in rural Central and Eastern Europe (CEE): the case of Pomerania,Poland

Despite empowerment being a crucial component of sustainable tourism, few scholars have quantitatively operationalized empowerment and looked at how it applies to rural societies within the post-communist European Union (EU) member states. Knowing the high priority of sustainable rural development goals within the EU, empowering residents within these post-communist societies has become a pertinent issue especially where those societies appear more reluctant to engaging in democratic ways of decision-making. In response to this gap, this study tests the cross-cultural validity of the Resident Empowerment through Tourism Scale, and then evaluates how empowerment predicts residents’ support for tourism within the municipality of Choczewo, Pomerania, Poland. Using a theoretical perspective that blends Social Exchange Theory with Weber's Theory of Formal and Substantive Rationality, these non-economic empowerment dimensions are coupled with a measure of resident perceptions of economically benefiting from tourism to see if rural residents in Choczewo, Poland, are more swayed by the economic or non-economic benefits of tourism. Results show that residents within this Central and Eastern Europe setting are more influenced by the pride and self-esteem boost associated with psychological empowerment and the perceptions of increased community cohesion (i.e. social empowerment) than the economic promises of tourism.

企业真诚型领导的结构维度研究

随着Eron、Tyco、WorldCom等公司丑闻和日益泛滥的管理渎职现象的出现,组织行为学中有关真诚领导的理论与实证研究受到了关注.然而,对中国背景下真诚型领导结构维度的研究还比较缺乏.在文献研究、深度访谈和问卷调查的基础上,对300名中小企业员工进行问卷调查,获得237份有效数据,采用探索性因子分析和验证性因素分析方法探究企业真诚型领导的结构维度.结果表明:我国企业真诚型领导由员工导向真诚、关系导向真诚、价值导向真诚、工作导向真诚行为四个维度构成.

Long‐run Effect of the Global Financial Crisis on Singapore's Tourism and the Economy

This study employs recent Singaporean tourism survey data, the updated Singaporean input–output tables and a computable general equilibrium model to gauge the long‐run effects of the 2008 global financial crisis and selected policy responses. The simulation results suggest that the global financial crisis has had mild negative long‐run effects on the overall development of Singapore's economy, and that the GST deduction policy ought to offset this negative effect.     

China’s Agricultural Policy Transition: Impacts of Recent Reforms and Future Scenarios

This article reviews recent developments in China’s agricultural domestic support policy, especially the transition from taxing farmers and agriculture to providing direct subsidies to grain production and purchased inputs. A model‐based quantitative analysis on the effects of these policy changes is presented. Simulation results suggest that recent policy changes have achieved the declared policy goals of increasing grain production and boosting farm income. Much of the increase in grain production and farm income can be attributed to higher per unit return to arable land, land reallocation to grain production and extra agricultural employment triggered by the policy changes. Based on the assumption that China’s public assistance to agriculture and farmers will continue and rise, two hypothetical future scenarios are simulated. Using all the support permitted under WTO de minimis limits with existing instruments, China’s policy will increase grain production, change trade patterns seemingly contrary to China’s comparative advantage, increase rural employment and significantly increase farm income (by more than 12%). If, however, decoupled instruments are applied to raise China’s agricultural domestic support to the same level, China’s agricultural production and trade will remain unchanged, rural employment remain stable, but farm income will be increased by nearly 15%.
