Abstract:
A flexible production function analysis is addressed to Namibia's data for the 1968-1992 period to test for evidence of structural problems in sectoral and sub-sectoral performance. The analysis found the primary sector to be characterized by constant returns to scale through the entire 25 years. The secondary sector experienced constant returns to scale pre-1980 and severe diseconomies post-1980, while the tertiary sector was marked by constant returns to scale pre-1980, and questionable increasing returns to scale post-1980. The changes imply structural problems inasmuch as factor productivities and the rates of technical change declined, and little support for domestic capital formation was found.
