In this article a simple multisector model for the Netherlands is presented with six sectors of production. Estimation and simulation results are based on input-output data for the period 1950–1968. Simple log-linear equations (containing both relative price factors and scale factors) are used to describe the demand for (intermediary and primary) factors of production and the demand for final output (including private investment). Sectoral product prices and wage rates are determined within the model. This applies to the generation of disposable income of households as well. Using this simple multisector model, actual economic developments during the 1955–1968 period can be simulated in a reasonably satisfactory way.
