''An argument against Cobb-Douglas production functions (in multi-sector growth modeling)''
( 2017, Vol. 37 No.2 )
 
 
Recent growth literature deals with long run cross-sector labor allocation dynamics in multi-sector growth models. We analyze what the adequate assumptions regarding the sectoral production functions in this type of (very long run) model are. By employing an axiomatic/geometrical approach, we demonstrate that the basic stylized facts of long run sector and aggregate dynamics and the standard theory axioms are not consistent with the assumption of Cobb-Douglas production functions at the sector level. This result can be regarded as an empirical rejection of the Cobb-Douglas production function (at the sector level) on the basis of very long run, qualitative data.
