This paper studies the emergence of convergence clubs in the United States since the 1980s. The finite mixture normal model is used to identify the clubs based on the per capita personal income dataset for 700 U.S. labor market areas from 1969 to 2009. The results reveal that the collection of high income areas, termed the "rich places club," was formed in the 1980s, and the share of the rich p...

In this paper, we examine the convergence hypothesis using a long memory framework that allows for structural breaks and does not rely on a benchmark country using both univariate and multivariate estimates of the long memory parameter d. Using per capita GDP gaps, we confirm the findings of non-stationarity and long memory behavior that have been found previously in the literature using univar...

abstract this paper presents a multiobjective power control algorithm that updates the transmitted power based on local information. the proposed algorithm is expanded by using multiobjective optimization schemes. the objectives to be optimized in this paper are determined so as to reduce the sinr fluctuations as well as maintaining the sinr to an acceptable level with minimizing an average tra...
