In time series context, estimation and testing issues with autoregressive and moving average (ARMA) models are well understood. Similar issues in the context of spatial ARMA models for the disturbance of the regression, however, remain largely unexplored. In this paper, we discuss the problems of testing no spatial dependence in the disturbances against the alternative of spatial ARMA process incorporating the possible presence of spatial dependence in the dependent variable. The problems of conducting such a test are twofold. First, under the null hypothesis, the nuisance parameter is not identified, resulting in a singular information matrix (IM), which is a nonregular case in statistical inference. To take account of singular IM, we follow Davies (Biometrika 64(2):247–254, 1977; Biometrika 74(1):33–43, 1987) and propose a test procedure based on the supremum of the Rao score test statistic. Second, the possible presence of spatial lag dependence will have adverse effect on the performance of the test. Using the general test procedure of Bera and Yoon (Econom Theory 9:649–658, 1993) under local misspecification, we avoid the explicit estimation of the spatial autoregressive parameter. Thus our suggested tests are entirely based on ordinary least squares estimation. Tests suggested here can be viewed as a generalization of Anselin et al. (Reg Sci Urban Econ 26:77–104, 1996). We conduct Monte Carlo simulations to investigate the finite sample properties of the proposed tests. Simulation results show that our tests have good finite sample properties both in terms of size and power, compared to other tests in the literature. We also illustrate the applications of our tests through several data sets. 相似文献

We investigate the effects of tax policy shocks on the U.S. economy over the 1972:3–2008:4 period within a structural vector autoregressive (SVAR) framework. Disaggregating tax shocks suggests that the positive output multipliers documented for total taxes by the previous literature are present only for indirect tax innovations. We also show that both labor and corporate taxes have similar effects on output, with labor tax multipliers being slightly larger in magnitude. The positive and negative responses of inflation following respectively corporate and labor tax shocks imply that former shocks work through aggregate supply, whereas the latter work predominantly through aggregate demand.

Beliefs about social competition affect redistributive demands and the responsibility assigned to government regarding public provisions. Given the strong link between beliefs and the extent of support for social protection, it is important to explain the cross‐country differences. The paper analyzes the factors that are crucial in explaining redistributive demands across developing countries with a special emphasis on beliefs about social competition. While ideas about luck versus effort in determining economic prospects are explanatory in every country, our findings also suggest that in societies with high economic volatility the role of beliefs is amplified. Vast fluctuations in economic performance fuel the opinion that economic failure is a result of systemic characteristics, and individuals are not necessarily held fully responsible for their material faiths in such settings. Therefore, government is assigned a greater role in basic provisioning. 相似文献

By employing cross-sectional data obtained from Survey of Income and Living Conditions for the years from 2007 to 2011, we analyze the identification problem of the poor by using both monetary and non-monetary measures. We classify the poor into the following categories: (i) poor in monetary and nonmonetary measures, (ii) poor in monetary measure only, (iii) poor in non-monetary measure only, and (iv) non-poor in both categories. We examine the determinants of each category by utilizing the probit model and find that the share of workers in adults — or the share of informal or agricultural workers — creates some disparities between poverty at a country and regional level. 相似文献

A common dilemma facing educational planners engaged in educational reform in developing countries is the allocation of sharply-reduced resources to the expansion of school facilities versus improvement of existing school facilities (say, by raising the teacher/pupil ratio). The empirical results presented in this paper for Kenya suggest that the two interventions have diametrically opposite effects on poor and nonpoor children. An expansion of school facilities increases the enrollment of children in the poorest expenditure quintiles but has no impact on the enrollment of children in the top quintiles. On the other hand, an improvement in the teacher-pupil ratio increases the enrollment rate of children in the top quintiles, and actually reduces the enrollment of children in the poor quintiles. These findings suggest that in situations where there is less than universal primary enrollment (UPE) and the government has set a time-bound goal of UPE, such as in Kenya, policies that serve to expand the number of school facilities may make more sense than interventions that increase the teacher-pupil ratio. 相似文献

This study surveyed customer perceptions about the environmentally friendly programs (i.e., green programs) in hotels and analyzed the degree to which such programs influenced customers' hotel selection. Data were collected from online travel communities by conducting Web-based online surveys. A total of members from 63 travel-related online communities participated in the survey. Multiple regression analysis results showed that the significant factors that affected client hotel selection were: Solid waste and water programs in guestrooms, energy programs, solid waste and water programs in housekeeping, and biodiversity programs. However, water program by customers' option did not influence customer decisions to stay at environmentally friendly hotels. Results also showed differences in customer awareness and demand for environmentally friendly hotels based on gender, income, and age. 相似文献

This paper address the extent of capital mobility and foreign debt sustainability in Turkey over the 1962–2003 period by examining the relationship between saving and investment, and imports and exports, respectively. The empirical investment is based on cointegration, error correction models, and threshold and momentum threshold autoregressive models. Our findings are consistent with the existence of capital mobility and the ‘Strong’ form of foreign debt sustainability. 相似文献

A three-stage Delphi study was conducted with experts and professionals working in the fields of disability and hospitality in order to identify some basic principles with respect to employment of people with disabilities (PWD). The potential effects of employing PWD on safety, cost, efficiency, service quality and management were investigated. Potentials and limitations of people with different types and degrees of disabilities with regard to jobs in the hospitality industry were also questioned. A notable guiding principle emanating from this study is that hiring of employees should be based on merit, suitability and capability of the candidate, regardless of the presence or degree of disability. Another important outcome is that the job or task appointed to PWD should not deteriorate the disability. A common guideline expressed by the participants was that jobs which critically require a certain sense or ability are not suitable for PWD who do not possess this sense or ability even with the aid of technology or by other means. However, apart from such extreme and obvious cases, experts mostly agree that PWD can fulfill any task in the hospitality industry as long as their professional knowledge and skills fit those tasks. 相似文献

During the socialist era, economists in the Balkan countries rarely published their work in the West due to political restrictions, methodological differences with the West, and inadequacy in Western languages. After the collapse of socialism, political barriers were lifted, a Western style of education in economics was adopted, and English began to be taught widely as the common language in the academic realm. The aim of this study is to discuss the impact of these policies on the publication performance of economists in the former socialist countries of the Balkans region. The results reveal that the number of international publications increased gradually over the post-socialist period and fast-reforming countries performed better than the slow movers. 相似文献
