Investment Frictions versus Financing Frictions [PDF]

SSRN Electronic Journal, 2009
Bertola/Caballero (1994) and Abel/Eberly (1996) extended Jorgenson's classical model of firms' optimal investment. By introducing investment frictions, they were able to capture the role of future anticipations in investment decisions as well as the lumpy and intermittent nature of investment dynamics. We extend Jorgenson's model to the other direction

A thermodynamic analytical model based on entropy production for predicting the grain size and yield strength of the joint formed by continuous drive friction welding

Journal of Materials Research and Technology, 2020
A self-consistent analytical model for predicting qualities of a joint welded by continuous drive friction welding (CDFW) was developed based on the Onsager-Ziegler maximum entropy production principle (OZ-MEPP), dislocation kinetics, and the CDFW ...
