We propose a semiparametric multivariate estimator and a multivariate score-type testing procedure under a perturbed multivariate fractional process. The estimator is based on the periodogram and uses a local Whittle criterion function which is generalised by an additional constant to capture...

We examine the evolution of educational assistance in Indonesia, following two decades of government decentralization, and its effect on education quality. Using Indonesia Family Life Survey data, we exploit as exogenous rule the variation in the implementation of government decentralization to...
