Structural Time Series Modelling of Capacity Utilisation

Proietti, Tommaso - Volkswirtschaftliche Fakultät, … - 1999

In this paper we introduce a structural non-linear time series model for joint estimation of capacity and its utilisation, thereby providing the statistical underpinnings to a measurement problem that has received ad hoc solutions, often underlying arbitrary assumptions. The model we propose is...
