Jones (2005) proposed microfoundations for the Cobb-Douglas production function. We show that Jones' technological menu is a special case of a concept of support set discussed by Matveenko (1997) and Rubinov, Glover (1998) by use of a duality approach. We use this approach to clarify the...

The Sennian capability approach has facilitated to capture poverty in its multi-dimensional incidence and thus to raise a new aggregate poverty index - the UNDP's Human Poverty Index (HPI). The UNDP has found power mean of order   1 as possessing some of the most desirable properties in...

By defining the Variable Output Elasticities Cobb-Douglas function, this article shows that a large class of production functions can be approximated by a Cobb-Douglas function with nonconstant output elasticity. Compared to standard flexible functions such as the Translog function, this...

We study an economy in which firms use labor and various vintages of capital in a CES production function for the final good. We explicitly solve for the investment in capital of a given vintage as a function of its age, and for the resulting stocks of capital. We show that for reasonable...
