Exchange Economics as an alternative to distributed optimization
Conference on Decision and Control, 2016Co-Authors: Anders RantzerAbstract:Quadratic optimization subject to linear constraints is a fundamental building-block in many other branches of applied mathematics. However, for large-scale systems, where a common global objective function is neither naturally defined nor easily computable, it is natural to view economic equilibrium theory as an alternative approach to design and analysis. Stability and robustness of equilibria can then be studied using the concept of monotonicity. In this paper we prove fundamental monotonicity properties for price dynamics with quadratic utilities. In particular, the main theorem gives quantitative bounds on the size of the monotone cone. Simple examples illustrate the ideas.

Essays in Economic Theory
'Edicions de la Universitat de Barcelona', 2017Co-Authors: Ribó AusiasAbstract:[eng] This thesis is composed of 3 independent essays on economic theory. Each essay is meant to be read separately, including footnotes and appendices. In particular, essays 2 and 3 include specific bibliography. The general bibliography is included at the end of the thesis. The first essay reviews some well known conceptual and empirical problems that appear when economic theorists deal with preferences and choice theory, in general. While assessing those problems, the essay lays the ground for a detailed discussion of the possibility of preference learning, formation and change. The essay concludes proposing a theoretical framework to study these phenomena. The second essay, although independent from the first, is also devoted to the issue of preference change. In particular, it studies the possibility that cultural preferences evolve as a result of the combination of technological innovation and cultural transmission mechanisms. At the same time, it allows for the possibility that those cultural preferences determine the short term outcome of economic variables. In addition, it builds a framework where the combination of technological innovation, cultural transmission and economic structure lead to a process of endogenous preference heterogeneity and clustering. Hence it provides a model to understand how culture and the economic structure interact and coevolve. The third essay presents some theoretical problems that arise when using the concept of a matching function as a modelling device for the labor market. In particular, necessary conditions for the ratio of the number of matches per job searcher to be interpreted as the average job finding probability are established. References [Abel, 1990] Abel, A.

Capacity Investment with a Capacity Exchange
2007Co-Authors: Christiaan HogendornAbstract:In many industries where capacity constraints are important, such as energy and telecommunications, firms can trade capacity in an Exchange. These Exchanges are modeled on commodities Exchanges for products like oil and soybeans, but they are focused on business-to-business trades between potentially competing firms. Some trades have been misused in accounting frauds (e.g. ENRON and Global Crossing), but the legitimate benefits are sufficient that Exchanges will continue to be important. In this paper, we examine the strategic investment effects of introducing a capacity Exchange ∗Economics Department, Wesleyan University. e-mail: chogendorn@wesleyan.edu. I

Archaeological Textiles: A Review of Current Research
Annual Review of Anthropology, 2001Co-Authors: Irene GoodAbstract:▪ Abstract Archaeological textile studies are now recognized as a robust source of information for anthropological inquiry. Over the past two decades several important developments have taken place, enabling a more integrated approach to their study than in the past. Topics addressed range from the development of methods for analyzing degraded fibers to the comparative study of specific histories of textile and clothing traditions. Archaeological textile studies address relevant issues ranging from aesthetics and style to gender; from technological development to production and Exchange Economics. This chapter presents an overview of current research in the growing field of archaeological textile studies.
