This paper introduces multi-quality firms within a Schumpeterian framework. Featuring non-homothetic preferences and income disparities in an otherwise standard quality-ladder model, I indeed show that the resulting differences in the willingness to pay for quality among consumers generate both...

We study the relation of financial contracting and the pace of technological advance in a dynamic agency theoretic model. A firm which is financed by outside shareholders but run by managers has the prospect of a process innovation which arrives stochastically. Adopting the innovation requires...
