The article suggests a manner in which degrees of monopoly power can be introduced into a trade policy model of the computable general equilibrium type. The distributional effects of tariffs and subsidies are compared, first under competitive conditions and then under conditions of monopoly power.The tin market, for which Malaysia can be assumed to exert monopoly power, is used as an example to show the distributional consequences of applying a competitive model in cases where a model allowing for monopoly power would have been more appropriate. The existence of monopoly power is shown to have important distributional effects. Policy modelers, dealing with distributional issues, should therefore be careful about the assumptions made about market forms. 相似文献

This is the first application of a new method for testing stationary random point processes. Consider the class of all stationary ergodic point processes on the real line with arbitrary dependences among the inter–point distances (spacing).The hypothesis is :The observed process φ is a homogeneous Poisson process or more (resp.less) regular than a Poisson process.The sample is the vector of the first n points t1, …,tn.There is a close relation between our method for testing and queueing theory: For finding an appropriate test statistic, we observe the behaviour of a single server queue with the input φ.A table of critical values is given. 相似文献

We propose optimal procedures to achieve the goal of partitioning k multivariate normal populations into two disjoint subsets with respect to a given standard vector. Definition of good or bad multivariate normal populations is given according to their Mahalanobis distances to a known standard vector as being small or large. Partitioning k multivariate normal populations is reduced to partitioning k non-central Chi-square or non-central F distributions with respect to the corresponding non-centrality parameters depending on whether the covariance matrices are known or unknown. The minimum required sample size for each population is determined to ensure that the probability of correct decision attains a certain level. An example is given to illustrate our procedures. 相似文献

Let (X1,…,Xk) be a multinomial vector with unknown cell probabilities (p1,?,pk). A subset of the cells is to be selected in a way so that the cell associated with the smallest cell probability is included in the selected subset with a preassigned probability, P1. Suppose the loss is measured by the size of the selected subset, S. Using linear programming techniques, selection rules can be constructed which are minimax with respect to S in the class of rules which satisfy the P1-condition. In some situations, the rule constructed by this method is the rule proposed by Nagel (1970). Similar techniques also work for selection in terms of the largest cell probability. 相似文献

We investigate a rate of convergence on asymptotic normality of the maximum likelihood estimator (MLE) for parameter appearing in parabolic SPDEs of the form where and are partial differential operators, is a cylindrical Brownian motion (CBM) and . We find an optimal Berry–Esseen bound for central limit theorem (CLT) of the MLE. It is proved by developing techniques based on combining Malliavin calculus and Stein’s method. 相似文献

The situation where k populations are partitioned into one inferior group and one superior group is considered. The statistical problem is to select a random size subset of superior populations while trying to avoid including any inferior populations. A selection procedure is assumed to satisfy the condition that the probability of selecting at least one superior population is bounded below by P1<1. The performance of a procedure is measured by the probability of including an inferior population.The asymptotic performance, as k→∞ of Gupta's traditional maximum type procedure ψG is considered in the location-model. For normally distributed populations, ψG turns out to be asymptotically optimal, provided the size of the inferior group does not become infinitely larger than the size of the superior group. 相似文献
