Drone food delivery services play a significant role in protecting the environment, because the services are operated by batteries that can be charged with electricity. Therefore, this study tried to examine a green image in the context of drone food delivery services. More specifically, this study proposed that a green image of drone food delivery services plays an important role in the formation of attitude toward using the services. In addition, it was hypothesized that the attitude has a positive influence on behavioral intentions including intentions to use, word‐of‐mouth intentions, and willingness to pay more. Lastly, the moderating role of gender and age was proposed during the theory‐building process. A theoretical model, which included 12 hypotheses, was developed and tested using a total of 427 samples collected in Korea. The data analysis results showed that a green image of drone food delivery services has a positive influence on attitude toward using the services, which in turn positively affects three subdimensions of behavioral intentions. Furthermore, gender and age played partly as a moderator. The current paper was the first to study the green image of drone food delivery services, so the findings of this study mean a lot to the theoretical aspect.  相似文献

This paper shows that there is no interior solution in Mai–Hwang's 1992 oligopolistic location model with free entry when the production function exhibits constant or decreasing returns to scale. The comparative static results of the impact of a demand change on the location decision only apply to the case where the production function exhibits increasing returns to scale. It re-examines the impact of a demand change on the location decision of an oligopolistic firm and corrects the propositions derived by [C.C. Mai, H. Hwang, Production-location decision and free entry oligopoly, Journal of Urban Economics 33 (1992) 252–271. Reprinted in: M.L. Greenhut, G. Norman (Eds.), The Economics of Location, vol. I: Location Theory, Edward Elgar, Aldershot, 1995].  相似文献

The study of divided government is one of important fields in public choice theory. American voters split their ballots as if intent on preserving divided party control. The U.S. House of Representatives has consistently been Democratic for much of the twentieth century. As indicated by Sprague, it is theoretically true that a number of significant consequences for partisan control of a legislature are entailed by the unequal distribution of seat safety under conditions of high levels of institutionalization. The problem is how to measure the institutionalization of partisan seat safety in a time‐series. The model proposed by Sprague is somewhat awkward and complicated in measuring it. This paper provides a more plausible model and tests empirical data.  相似文献

An i.i.d. bootstrap is applied for the ratio test of Barndorff-Nielsen and Shephard (2006) for jumps in jump diffusion processes. Asymptotic validity is established for the bootstrap test both under the null of no jump and under the alternative of jumps. Finite sample simulation shows that the bootstrap test has more stable size than the ratio test of Barndorff-Nielsen and Shephard (2006).  相似文献

美国推进会计准则国际趋同的最新动向及思考   总被引:1,自引:0,他引:1  
目前世界主要经济体几乎均已采用国际财务报告准则或发布了趋同路线图.我国已草拟了我国企业会计准则(CAS)与国际财务报告准则(IFKS)全面趋同的路线图,将\"实质性趋同\"推进到\"全面趋同\".然而,国际趋同是一个艰难的、互动的过程,我国现阶段国际趋同的成效只能说是刚刚迈出了第一步,随着国际会计准则理事会(IASB)应对金融危机重大项目的完成.我国会计准则可能再次与国际准则产生众多差异.作为积极推动会计准则国际趋同的重要力量,美国积极推行国际趋同所经历的战略转变以及所采取的措施,对我国会计准则国际趋同及其未来发展将具有重要的影响作用.本文拟通过追踪美国采用IFRS的进展和动态情况,阐述美国各界人士对采用IFRS的不同观点,旨在对我国会计准则国际趋同的未来提供借鉴.  相似文献

This paper analyzes the role of central government in a Nash tax competition between two heterogenous regions, which differ in their endowments of two production factors. Regional governments use a source-based unit tax on mobile capital to finance their public service expenditures. The central government employs excise subsidies and lump-sum taxes to induce the two regions to efficient resource allocations. We answer to the question that whether the central government can induce an efficient equilibrium, and investigate the effects of endowments difference on the optimum subsidy rates. We find that there exists a unique tax rate under which the efficiency is achieved. We identify the set of endowment allocations for which the subsidy rate to one region is higher (or lower) than the subsidy rate to the rival. The large poor region receives a higher subsidy than the small rich region, but the subsidy to the small poor region may be higher or lower than that to the large rich region. [H2]  相似文献

Scholars and policymakers have long been concerned about the lack of financial knowledge and the socioeconomic disparities in financial knowledge in the United States. The objectives of this study are (1) to assess the extent of income-related inequality in financial knowledge and how it changed between 2012 and 2018 and (2) to determine what factors explain the income-related inequality in financial knowledge and the change over time. Using National Financial Capability Study datasets, our study revealed that from 2012 to 2018 there was income-related inequality in financial knowledge. Financial experience, education, and numeracy were major contributing factors to inequality in financial knowledge, according to decomposition analysis. Income-related inequality in financial knowledge in the United States decreased between 2012 and 2018, mainly due to an overall change in financial experience. This study provides meaningful insights to policymakers and educators interested in improving financial knowledge in the United States.  相似文献

This study examines whether rates of information flow differbetween trading and nontrading periods, and whether the variancesof pricing errors differ at the open and close of trading. Theapproach improves on existing methods by allowing for correlationbetween pricing errors and information flow, and by conductinginferences at the individual security level. The daytime rateof information flow is about seven times the overnight rate,and the variances of pricing errors at the open are not differentfrom those at the close of trading. This evidence differs fromexisting results based on return variance ratios.  相似文献

Although economists usually support the unrestricted entry of firms into an industry, entry may lower social welfare if there are setup costs or if entrants have a cost disadvantage. We consider the welfare effects of entry within a standard Cournot model where some of an incumbent firm’s costs are sunk. We find that the range of parameter values over which entry can harm welfare declines monotonically in the fraction of cost that are sunk. Furthermore, the presence of even a small fraction of sunk costs often reverses an assessment that entry harms welfare.  相似文献

Abstract:  We propose generalised stochastic volatility models with Markov regime changing state equations (SVMRS) to investigate the important properties of volatility in stock returns, specifically high persistence and smoothness. The model suggests that volatility is far less persistent and smooth than the conventional GARCH or stochastic volatility. Persistent short regimes are more likely to occur when volatility is low, while far less persistence is likely to be observed in high volatility regimes. Comparison with different classes of volatility supports the SVMRS as an appropriate proxy volatility measure. Our results indicate that volatility could be far more difficult to estimate and forecast than is generally believed.  相似文献
