Most macroeconomic models assume that aggregate output is generated by a specification for the production function with total physical capital as a key input. Implicitly this assumes that private and public capital stocks are perfect substitutes. In this paper we test this assumption by...

Using a multivariate filter, we estimate potential growth rates in Chile's mining and non-mining sectors. Estimates for the mining sector incorporate information on copper prices, whereas estimates for non-mining reflect information on inflation and unemployment rates. To better understand the...

This paper presents estimates of potential output for all Central American economies. Our findings are that potential output growth has declined in recent years in most economies of Central America. Lower capital accumulation and TFP growth are accounting for most of this decline. Apart from...

A growth accounting exercise is conducted for 88 countries for 1960-94 to examine the source of cross-country differences in total factor productivity (TFP) levels. Two differences distinguish this analysis from that of the related literature. First, the critical technology parameter—the share...

The knowledge production function is central to R&D-based growth models. This paper empirically investigates the knowledge production function and intertemporal spillover effects using cointegration techniques. Time-series evidence suggests there are two long-run cointegrating relationships. The...

Data on the weekly operating time of capital improve the measurement of effective capital input in production. The production function of the French business sector is found to be consistent with a Cobb-Douglas technology under constant returns to scale. Total factor productivity growth,...

The paper investigates the sources of growth in the Democratic Republic of the Congo since 1960 and evaluates the relative importance of total factor productivity growth and factor accumulation, using a cointegration method and a growth accounting framework. The main findings confirm that poor...

The paper develops a methodology based on the production-function approach to estimate potential output of the Polish economy. The paper concentrates on obtaining a robust estimate of the labor input by deriving Poland''s natural rate of unemployment. The estimated unemployment gap is found to...
