This paper proposes a new testing procedure for the degree of fractional integration of a time series inspired on the unit root test of Dickey-Fuller (1979). The composite null hypothesis is that of d=d0 against d<d0. The test statistics is the same as in Dickey-Fuller test, exploiting the fact that if the process, under study, is I(d0) then the (-1+d0)th differenced series is I(1) under the null d=d0. If d>=d0, using the generalization of Sowell's results (1990), we propose a test based...</d0.>

Extreme Value Theory is increasingly used in the modelling of financial time series. The non-normality of stock returns leads to the search for alternative distributions that allows skewness and leptokurtic behavior. One of the most used distributions is the Pareto Distribution because it allows...

When estimating regional inequality, many economists use inequality indices weighted by the regions' shares in the national population. Although this approach is widespread, its adequacy has not received attention in the regional science literature. This paper proves that such approach is...
