We address the problem of finding location equilibria of a location-price game where firms first select their locations and then set delivered prices in order to maximize their profits. Assuming that firms set the equilibrium prices in the second stage, the game is reduced to a location game for which a global minimizer of the social cost is a location equilibrium if demand is completely inelas...

In this paper, a quasi-negative binomial distribution (QNBD) derived from the class of generalized Lagrangian probability distributions is studied. The negative binomial distribution is a special case of QNBD. Some properties of QNBD, including the upper tail behavior and limiting distributions, are investigated. It is shown that the moments do not exist in some situations and the limiting dist...

Positive correlations between diversity and stability have been reported for a number of ecosystems and are thought to be caused by a stabilizing effect of differential species’ responses to environmental perturbation. Empirical field studies in which investigators tested for diversity–stability relationships are lacking for some taxonomic groups and typically have not included tests of the imp...

I briefly review some of the micro and macro theory of corruption and relate it to various socio-economic and political variables. To quantify the burden of corruption I use Harrison and Vinod's (1992) 95% confidence interval for the marginal excess burden (MEB) of taxation. In developing countries, one dollar of corruption is estimated to impose a burden of $1.67, which becomes very large when...

Akaike's criterion is used to test composite hypotheses ; for example to determine the order of AR models. A modiication is presented to test composite hypotheses given an upper-bound on the error of the rst kind (Neyman-Pearson). The presented theory is applied to AR order estimation and veriied by simulations. The experimental results are so good that we consider the AR order estimation probl...

During manual driving, most human drivers often use information about the speed and position of the preceding and following vehicles in order to adjust the position and speed of their vehicles. The purpose of this paper is to design an autonomous intelligent cruise control (AICC) which mimics this human driving behavior. The proposed AICC law uses relative speed and spacing information from the...

Many spatial processes in environmental applications, such as climate variables and climate model errors on a global scale, exhibit complex nonstationary dependence structure, in not only their marginal covariance but also their cross-covariance. Flexible crosscovariance models for processes on a global scale are critical for an accurate description of each spatial process as well as the cross-...

The problem of simplicity involves three questions: How is the simplicity of a hypothesis to be measured? How is the use of simplicity as a guide to hypothesis choice to be justified? And how is simplicity related to other desirable features of hypotheses -that is, how is simplicity to be traded-off? The present paper explores these three questions, from a variety of viewpoints, including Bayes...
