A new test is proposed for the null of absence of serial correlation. The test uses a data-driven smoothing parameter. The resulting test statistic has a standard limit distribution under the null. The smoothing parameter is calibrated to achieve rate-optimality against several classes of...

We consider a small structural model to describe the transmission mechanism of monetary policy and the dynamics of inflation. We first verify the validity of the general structure estimating it for Germany which represents a sort of benchmark model. At least one of the links required for the...

The CEEC are approaching the accession to the EU with a variety of exchange rate regimes. The authors find that these differences depend on economical factors as well as on the history of the countries. For that purpose, they discuss the role of the exchange rate in the stabilization of the...

Lobato and Robinson (1998) develop semiparametric tests for the null hypothesis that a series is weakly autocorrelated, or I(0), about a constant level, against fractionally integrated alternatives. These tests have the advantage that the user is not required to specify a parametric model for...

The English National Health Service was established in 1948, and has therefore yielded some long time series data on health system performance. Waiting times for inpatient care have been a persistent cause of policy concern since the creation of the NHS. This paper develops a theoretical model...
