A general model of technical change with an application to the OECD countries
Heshmati, Almas; Kumbhakar, Subal - 2011
In the neoclassical production functions model technical change (TC) is assumed to be exogenous and it is specified as a function of time. However, some exogenous external factors other than time can also affect the rate of TC. In this paper we model TC via a combination of time trend (purely...
