The Rouwenhorst method of approximating stationary AR(1) processes has been overlooked by much of the literature despite having many desirable properties unmatched by other methods. In particular, we prove that it can match the conditional and unconditional mean and variance, and the first-order autocorrelation of any stationary AR(1) process. These properties make the Rouwenhorst method more reliable than others in approximating highly persistent processes and generating accurate model solutions. To illustrate this, we compare the performances of the Rouwenhorst method and four others in solving the stochastic growth model and an income fluctuation problem. We find that (i) the choice of approximation method can have a large impact on the computed model solutions, and (ii) the Rouwenhorst method is more robust than others with respect to variation in the persistence of the process, the number of points used in the discrete approximation and the procedure used to generate model statistics. 相似文献

In this paper, we show that the 1986 Mitra–Wan result establishing asymptotic convergence of maximal programs to the unique golden-rule forest in the case of undiscounted, strictly concave felicity functions can be strengthened, in the same setting, to the uniform asymptotic convergence of optimal programs to the unique golden-rule forest. We work with a notationally reformulated version of the model that may have independent interest. 相似文献

Whether or not an advertisement is said to be deceptive depends on the understanding and definition of deception being used. The position advocated here is that the focus of any definition must be the receiver of the message. Based on an analysis of veridical perception, a definition of deception in advertising is offered. An approach to measuring deception is also offered. The techniques are all seen as screening techniques, although by their regular use, advertisers should improve the ability of their advertisements to reach their stated objectives as well as reduce the amount of deception. 相似文献

The test-score gap between black and white students should be seen as a crisis. We propose a testable model based on readily available data that will allow us to estimate the impact and interrelationships of a multitude of factors that may be partially responsible for the problem. The estimation of this model will require the joint efforts of experts in many areas of education as well as of experts in multilevel structural equation modeling. 相似文献

The current study reviews consumer purchasing of locally produced foods in retail grocery stores across Hispanic and Caucasian groups in the United States. Six hypotheses were tested via the creation and evaluation of a measurement model within the structural equation modeling process. Results suggested that group differences exist between Hispanic and Caucasian consumers across the constructs of attitudes, perceived product availability, subjective norms, intention to purchase and extent of purchase. Implications for marketing strategies across groups and product categories are provided, along with future research directions. 相似文献

The purpose of this article is to identify the extent of inward and outward foreign direct investment (FDI) worldwide. A large number of countries were aggregated on a regional basis to examine their inward and outward stocks as a percentage of gross fixed capital formation for the period 1980–2006. Among the findings was that the annual increase for both inward and outward FDI was less than 1%. Also, countries grouped by the aggregates developed, Africa, Latin America and Caribbean, Asia and Oceania, and developing were found to differ significantly in their means. 相似文献

Although evidence of a link between socioeconomic status and child health has been researched extensively, much less attention
has been devoted to studying the link between child health and cognitive development. This paper seeks to determine whether
early childhood illnesses and poverty significantly impede cognitive development. The empirical model attempts to control
for observed and unobserved heterogeneity through the use of panel data models. Results indicate that a child’s cognitive
development is not directly related to health problems acquired after birth or socioeconomic standing. Rather, cognitive development
is primarily influenced by unobserved child- and family-specific factors that happen to be correlated with health and socioeconomic
status. On the other hand, birth weight appears to affect cognitive performance later in childhood, even after taking unobserved
heterogeneity into account. 相似文献

The purpose of this study was to investigate the relationship between training evaluation and the transfer of training in organizations. We hypothesized that training evaluation frequency will be related to higher rates of transfer because evaluation information can identify weaknesses that lead to improvements in training programs and create greater accountability among stakeholders for training outcomes. The data were obtained from 150 training professionals who were members of a training and development association in Canada. The results indicated that training evaluation frequency is positively related to training transfer. However, among Kirkpatrick's four levels of evaluation criteria, only behavior and results criteria were related to higher rates of transfer of training, indicating that the level of evaluation criteria is important for training transfer. These results indicate the importance of organizational‐level initiatives such as training evaluation in addition to individual‐level practices for facilitating the transfer of training. 相似文献
