In this project we will analyse specific economic factors of O.U.T.A. (Organism of Urban and Transportations of Athens. O.U.T.A. is a legal person of private law and was established in according to the law 2175/1993, as a successor of O.U.T. . (Organism of Urban and Transportations). O.U.T. was...

Grocer is an econometric toolbox for Scilab, a free opensource matrix- oriented toolbox similar to Matlab and Gauss. It contains more than 50 econometric different methods, with many variants and extensions. Most standard econometric tools are available. Grocer contains also two original...

The paper illustrates finite sample problems of regression models with I(1) variables. The importance of drifts on test statistics is analysed both analytically and by simulation methods. Moreover, Haavelmo's famous example for the presence of some simultaneous equation bias is considered in the...

This is a survey paper on five important developments in econometrics, with illustrative applications to economic policy formation in Taiwan, Mainland China and the United States.

This paper discusses estimation methods for limited dependent variable (LDV) models that employ Monte Carlo simulation techniques to overcome computational problems in such models. These difficulties take the form of high dimensional integrals that need to be calculated repeatedly but cannot be...

This study estimates the impact of the municipal groupings between 1992 and 2000 upon municipalities's wage bill in Quebec. Our identification strategy is based on a wage bill reduced form model and the specification of the grouping participation process. The three following methods are used in...

This paper reviews the literature on Bartlett and Bartlett-type corrections. It focuses on the corrections to the likelihood ratio, score and Wald test statistics. Three different Bartlett-type corrections which are equivalent to order 1/n, n being the sample size, are compared through...

Under suitable regularity conditions, an improved score test was derived by Cordeiro and Ferrari (1991). The test is based on a corrected score statistic which has a chi-squared distribution to order 1/n under the null hypothesis, where n is the sample size. In this paper we follow their...
