Real analysis with economic applications by Efe A Ok( Book )
12 editions published between 2007 and 2013 in English and held by 316 libraries worldwide
"There are many mathematics textbooks on real analysis, but they focus on topics not readily helpful for studying economic theory or they are inaccessible to most graduate students of economics. Real Analysis with Economic Applications aims to fill this gap by providing an ideal textbook and reference on real analysis tailored specifically to the concerns of such students." "The emphasis throughout is on topics directly relevant to economic theory. In addition to addressing the usual topics of real analysis, this book discusses the elements of order theory, convex analysis, optimization, correspondences, linear and nonlinear functional analysis, fixed-point theory, dynamic programming, and calculus of variations. Efe Ok complements the mathematical development with applications that provide concise introductions to various topics from economic theory, including individual decision theory and games, welfare economics, information theory, general equilibrium and finance, and intertemporal economics. Moreover, apart from direct applications to economic theory, his book includes numerous fixed point theorems and applications to functional equations and optimization theory." "The book is rigorous, but accessible to those who are relatively new to the ways of real analysis. The formal exposition is accompanied by discussions that describe the basic ideas in relatively heuristic terms, and by more than 1,000 exercises of varying difficulty." "This book will be an indispensable resource in courses on mathematics for economists and as a reference for graduate students working on economic theory."--Jacket
Social mobility and the demand for redistribution : the POUM hypothesis by Roland Benabou( Book )
23 editions published in 1998 in English and held by 126 libraries worldwide
Even relatively poor people oppose high rates of redistribution because of the anticipation that they or their children may move up the income ladder. This hypothesis commonly advanced as an explanation of why most democracies do not engage in large-scale expropriation and highly progressive redistribution. But is it compatible with everyone -- especially the poor -- holding rational expectations that not everyone can simultaneously expect to end up richer than average? This paper establishes the formal basis for the POUM hypothesis. There is a range of incomes below the mean where agents oppose lasting redistributions if (and, in a sense, only if) tomorrow's expected income is increasing and concave in today's income. The laissez-faire coalition is larger, the more concave the transition function and the longer the policy horizon. We illustrate the general analysis with an example (calibrated to the U.S.) where, in every period, 3/4 of families are poorer than average, yet a 2/3 majority has expected future incomes above the mean, and therefore desires low tax rates for all future generations. We also analyze empirical mobility matrices from the PSID and find that the POUM effect is indeed a significant feature of the data
Mobility as progressivity : ranking income processes according to equality of opportunity by Roland Benabou( Book )
15 editions published between 2000 and 2001 in English and held by 61 libraries worldwide
Abstract: Interest in economic mobility stems largely from its perceived role as an equalizer of opportunities, though not necessarily of outcomes. In this paper we show that this view leads very naturally to a methodology for the measurement of social mobility which has strong parallels with the theory of progressive taxation. We characterize opportunity--equalizing mobility processes, and provide simple criteria to determine when one process is more equalizing than another. We then explain how this mobility ordering relates to social welfare analysis, and how it differs from existing ones. We also extend standard indices of tax progressivity to mobility processes, and illustrate our general methodology on intra- and intergenerational mobility data from the United States and Italy
Interdependent preference formation by Efe A Ok( Book )

Essays on Decision Theory by Leandro Nascimento( file )
1 edition published in 2011 in English and held by 8 libraries worldwide
This dissertation consists of three essays on decision making under uncertainty. Chapter 1 characterizes models of ambiguous beliefs in the absence of the completeness axiom. The axiomatic work achieves two objectives. First, given the criticism that stems from the Ellsberg paradox, it drops the independence axiom from the Anscombe-Aumann framework, and considers a restricted version that applies to constant acts only. Second, given the lack of normative justification for the completeness axiom, it considers a weaker version (partial completeness) originally proposed by Bewley (1986). The simultaneous weakening of independence and completeness gives rise to multiple-selves versions of some of the most important examples of complete and ambiguity averse preferences. The chapter also characterizes when those incomplete preferences are ambiguity averse
Essays in Decision Theory by Stefania Minardi( file )
1 edition published in 2012 in English and held by 8 libraries worldwide
Well-known empirical and experimental evidence shows that individuals often exhibit behavioral traits which are inconsistent with the standard rationality tenets dictated by Savage's (1954) model and the self-interested utility maximization. The contribution of this dissertation is to provide axiomatic models of decision-making which accommodate some of these behavioral traits
Essays on Framing Effects by Begum Guney( file )
1 edition published in 2011 in English and held by 8 libraries worldwide
This research studies different types of framing effects. In the first chapter, we develop an axiomatic model to analyze how unobservable, and possibly unavailable, aspirations influence choices. According to our model, when confronted with a set of alternatives some of which are possibly unavailable, the decision maker chooses available alternatives that are closest (with respect to a psychological distance function in her mind) to her endogenously determined aspiration. We then apply this model to several economic problems and find that our model's predictions are consistent with experimental regularities documented in sales/discount events, second-price auctions, and ultimatum games
