CSR related management practices and Firm Performance: An Empirical Analysis of the Quantity-Quality Trade-off on French Data (2015, background): “It is important to point out that the definitions of complementarity and substitutability that we use are borrowed from Athey and Stern (1998), and they are actually close to the notions of supermodularity and submodularity in game theory (see Amir, 2005, for a survey).”
The Scope of Cooperation: Values and Incentives (2008, unknown): “Equation (10) de nes ft as a known function of Y 1 t ; ft = F (Y 1 t ) - all other terms on the right hand”
Incidence and Growth of Patent Thickets - the Impact of Technological Opportunities and Complexity (2013, unknown): “To prove Proposition 1 we show in Appendix B that firms’ profit functions are supermodular (i) in their own actions and (ii) in every combination of their own actions with those of rival firms (Milgrom and Roberts, 1990, Vives, 1999, 2005, Amir, 2005).”
The Scope of Cooperation: Norms and Incentives (2007, background): “Y 0 = [lnd − lnw]/θ0 (7) Y 1 = [lnd − ln[(w − l)n + l]]/θ1 ( 8 )”
