The central argument of this paper is that both - internal and external - equilibria should be taken into account in the estimation of potential output. If only the data on inflation, unemployment rate, and wages are used for its evaluation, no certainty exists that such a level will correspond...

The paper is organized in four chapters. The first describes the methodological framework of the investigation, insisting on defining the sectoral changes and the relative prices, as well as on their interaction (as expectations and as real processes); the theoretical considerations are...

We propose a robust estimator in the errors-in-variables model using the least trimmed squares estimator. We call this estimator the orthogonal least trimmed squares (OLTS) estimator. We show that the OLTS estimator has the high breakdown point and appropriate equivariance properties. We develop...

Principalul scop al acestui studiu este să prezinte o tehnică de modelare care este regresia ortogonală sau modelul EIV cu erori-în-variabile şi posibilele aplicaţii în economie. Metodele de calcul şi principalele proprietăţi statistice ale estimatorilor sunt discutate. In partea...
