By passing through various periods in which labor force, resources and capital, each one at a certain time, have been comparative and competitive advantages for a more powerful...

This paper studies the self-weighted least squares estimator (SWLSE) of the ARMA model with GARCH noises. It is shown that the SWLSE is consistent and asymptotically normal when the GARCH noise does not have a finite fourth moment. Using the residuals from the estimated ARMA model, it is shown...

We show how economies of scale may be distinguished from technical progress and how both may be simultaneously identified in the empirical analysis of aggregate economic growth. Using the meta-production function framework and a cross-section of time-series macroeconomic data on inputs and...
