Welfare variations and the comparative statics of demand

Index-Wise Comparative Statics

“…Instead, this paper explores monotone comparative statics in situations where an exogenous parameter of the model changes an agent's objective function; this class of problems was explored by TMS as well as Athey (2002) and Quah and Strulovici (2009). More generally, this paper contributes to the groundwork laid by Shirai (2009Shirai ( , 2013 in developing a functional and accessible generalization of lattice theory for applied economic problems.…”

“…The second research area from which index-wise comparative statics draws is Shirai (2009Shirai ( , 2013. These papers are the first (to the best of Shirai's and my knowledge) to develop monotone comparative statics from an extended version of lattice theory based on quasi-ordered sets.…”

“…In economic theory, comparative statics concerns the way in which economic predictions change as a function of the model's exogenous parameters. 1 For example, a comparative statics analysis would involve investigating how a consumer's purchasing behavior changes as a function of prices (Quah, 2007;Shirai, 2013), ambiguity impacts portfolio choices and asset prices (Gollier, 2011), and how the distribution of productivity and labor income changes as a function of earning uncertainty (Acemoglu and Jensen, 2015).…”
