Frictional and Non‐Frictional Unemployment in a Labor Market with Matching Frictions [PDF]
The Manchester School, 2016 Using the Mortensen and Pissarides model of a labor market with frictions, this paper proposes a new method, simpler than the one presented in Michaillat (), for decomposing unemployment into frictional and non‐frictional (rationing) unemployment for a derived rigid wage‐setting rule.

Investigation and modelling of rubber friction [PDF]
, 2010 PhDThe friction between a rubber surface in contact with a rigid surface is still not fully understood. Unlike other materials, friction behaviour in rubber is significantly dependent upon a variety of parameters due to its viscoelastic nature. The aim

Simulation of Adhesive Contact of Soft Microfibrils
Lubricants, 2020 Adhesive contact between a flat brush structure with deformable microfibrils and an elastic half space is numerically simulated. The stiffness of pillars is modeled by linear springs.

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
