Utility, Ethics and Behavior
Journal of Academic and Business Ethics Utility, ethics and behavior Marcela Parada-Contzen Universidad de Concepcion-Chile Jose R. Parada-Daza Universidad de Concepcion-Chile ABSTRACT This essay has the following hypothesis as its foundation: a new function taking a more global perspective can be developed based on the analytical economic conception of utility. However, this new hypothesis/perspective considers that individuals are driven to act by economic as well as social, religious, ethical, and other reasons. Thus, the crux of this exposition is an analysis of the concept of utility and its application towards daily acts. The essay also deals with the philosophical aspects of utility and its paradoxes and analyzes utility from the perspective of a biological being. This analysis is broader and includes the simultaneous actions of an economic human and a complex human. Keyword: Utility function, Emotional well-being, wealth, ethics, “homo economicus”, weights. Utility, ethics and behavior, Page 1 Journal of Academic and Business Ethics INTRODUCTION The study of what motivates individual acts, especially regarding economic decisions, offers an intellectual challenge for the human sciences. In economics, this matter has been studied using a methodology of normative analysis known as the utility function, in which people seek to obtain the maximum degree of satisfaction. Herein, utility is what each person obtains from a certain level of wealth or consumption. For those not instructed in economics, this idea creates distrust and is blamed for generating a society of individualistic and insatiable beings. Grounds for both supporting and distrusting this approach have been given. The utility function is an intellectual device for explaining personal economic behavior. -
Utility and Happiness in a Prosperous Society
Utility and Happiness in a Prosperous Society Yoram Kirsh1,2 1 Institute for Policy Analysis, The Open University of Israel 2 Department of Natural Sciences, The Open University of Israel Version: March 30, 2017 Keywords: Prosperous society, Utility, Happiness economics JEL Classification: D63, D64, I31 This article is scheduled to be a chapter in a book on the economics of the prosperous society. My claim is that there is a gap between economic theory and economic reality in the western world, since economics was traditionally established to deal with conditions of scarcity. As many of our current problems are associated with abundance rather than with scarcity, new tools are needed to tackle the modern dilemmas. For a definition of a prosperous society, please see the previous chapter (Unemployment and Job Creation in a Prosperous Economy). I would be grateful for any suggestion or comment.

The first type is the conventional utility – cardinal or ordinal – which the rational economic actors are expected to maximize. The second type is connected to actions which fulfill some psychological needs and might appear irrational by cost- effective calculations. -

Utility and Happiness Miles Kimball and Robert Willis1 University of Michigan October 30, 2006 Abstract: Psychologists have developed effective survey methods of measuring how happy people feel at a given time. The relationship between how happy a person feels and utility is an unresolved question. Existing work in Economics either ignores happiness data or assumes that felt happiness is more or less the same thing as flow utility. The approach we propose in this paper steers a middle course between the two polar views that “happiness is irrelevant to Economics” and the view that “happiness is a sufficient statistic for utility.” We argue that felt happiness is not the same thing as flow utility, but that it does have a systematic relationship to utility. In particular, we propose that happiness is the sum of two components: (1) elation--or short-run happiness--which depends on recent news about lifetime utility and (2) baseline mood--or long-run happiness--which is a subutility function much like health, entertainment, or nutrition. In principle, all of the usual techniques of price theory apply to baseline mood, but the application of those techniques is complicated by the fact that many people may not know the true household production function for baseline mood. If this theory is on target, there are two reasons data on felt happiness is important for Economics. First, short-run happiness in response to news can give important information about preferences. Second, long-run happiness is important for economic welfare in the same way as other higher-order goods such as health, entertainment, or nutrition. -
Product Differentiation
Product differentiation Industrial Organization Bernard Caillaud Master APE - Paris School of Economics September 22, 2016 Bernard Caillaud Product differentiation Motivation The Bertrand paradox relies on the fact buyers choose the cheap- est firm, even for very small price differences. In practice, some buyers may continue to buy from the most expensive firms because they have an intrinsic preference for the product sold by that firm: Notion of differentiation. Indeed, assuming an homogeneous product is not realistic: rarely exist two identical goods in this sense For objective reasons: products differ in their physical char- acteristics, in their design, ... For subjective reasons: even when physical differences are hard to see for consumers, branding may well make two prod- ucts appear differently in the consumers' eyes Bernard Caillaud Product differentiation Motivation Differentiation among products is above all a property of con- sumers' preferences: Taste for diversity Heterogeneity of consumers' taste But it has major consequences in terms of imperfectly competi- tive behavior: so, the analysis of differentiation allows for a richer discussion and comparison of price competition models vs quan- tity competition models. Also related to the practical question (for competition authori- ties) of market definition: set of goods highly substitutable among themselves and poorly substitutable with goods outside this set Bernard Caillaud Product differentiation Motivation Firms have in general an incentive to affect the degree of differ- entiation of their products compared to rivals'. Hence, differen- tiation is related to other aspects of firms’ strategies. Choice of products: firms choose how to differentiate from rivals, this impacts the type of products that they choose to offer and the diversity of products that consumers face. -
I. Externalities
Economics 1410 Fall 2017 Harvard University SECTION 8 I. Externalities 1. Consider a factory that emits pollution. The inverse demand for the good is Pd = 24 − Q and the inverse supply curve is Ps = 4 + Q. The marginal cost of the pollution is given by MC = 0:5Q. (a) What are the equilibrium price and quantity when there is no government intervention? (b) How much should the factory produce at the social optimum? (c) How large is the deadweight loss from the externality? (d) How large of a per-unit tax should the government impose to achieve the social optimum? 2. In Karro, Kansas, population 1,001, the only source of entertainment available is driving around in your car. The 1,001 Karraokers are all identical. They all like to drive, but hate congestion and pollution, resulting in the following utility function: Ui(f; d; t) = f + 16d − d2 − 6t=1000, where f is consumption of all goods but driving, d is the number of hours of driving Karraoker i does per day, and t is the total number of hours of driving all other Karraokers do per day. Assume that driving is free, that the unit price of food is $1, and that daily income is $40. (a) If an individual believes that the amount of driving he does wont affect the amount that others drive, how many hours per day will he choose to drive? (b) If everybody chooses this number of hours, then what is the total amount t of driving by other persons? (c) What will the utility of each resident be? (d) If everybody drives 6 hours a day, what will the utility level of each Karraoker be? (e) Suppose that the residents decided to pass a law restricting the total number of hours that anyone is allowed to drive. -
Utility with Decreasing Risk Aversion
144 UTILITY WITH DECREASING RISK AVERSION GARY G. VENTER Abstract Utility theory is discussed as a basis for premium calculation. Desirable features of utility functions are enumerated, including decreasing absolute risk aversion. Examples are given of functions meeting this requirement. Calculating premiums for simplified risk situations is advanced as a step towards selecting a specific utility function. An example of a more typical portfolio pricing problem is included. “The large rattling dice exhilarate me as torrents borne on a precipice flowing in a desert. To the winning player they are tipped with honey, slaying hirri in return by taking away the gambler’s all. Giving serious attention to my advice, play not with dice: pursue agriculture: delight in wealth so acquired.” KAVASHA Rig Veda X.3:5 Avoidance of risk situations has been regarded as prudent throughout history, but individuals with a preference for risk are also known. For many decision makers, the value of different potential levels of wealth is apparently not strictly proportional to the wealth level itself. A mathematical device to treat this is the utility function, which assigns a value to each wealth level. Thus, a 50-50 chance at double or nothing on your wealth level may or may not be felt equivalent to maintaining your present level; however, a 50-50 chance at nothing or the value of wealth that would double your utility (if such a value existed) would be equivalent to maintaining the present level, assuming that the utility of zero wealth is zero. This is more or less by definition, as the utility function is set up to make such comparisons possible. -

Economic Evaluation Glossary of Terms A Attributable fraction: indirect health expenditures associated with a given diagnosis through other diseases or conditions (Prevented fraction: indicates the proportion of an outcome averted by the presence of an exposure that decreases the likelihood of the outcome; indicates the number or proportion of an outcome prevented by the “exposure”) Average cost: total resource cost, including all support and overhead costs, divided by the total units of output B Benefit-cost analysis (BCA): (or cost-benefit analysis) a type of economic analysis in which all costs and benefits are converted into monetary (dollar) values and results are expressed as either the net present value or the dollars of benefits per dollars expended Benefit-cost ratio: a mathematical comparison of the benefits divided by the costs of a project or intervention. When the benefit-cost ratio is greater than 1, benefits exceed costs C Comorbidity: presence of one or more serious conditions in addition to the primary disease or disorder Cost analysis: the process of estimating the cost of prevention activities; also called cost identification, programmatic cost analysis, cost outcome analysis, cost minimization analysis, or cost consequence analysis Cost effectiveness analysis (CEA): an economic analysis in which all costs are related to a single, common effect. Results are usually stated as additional cost expended per additional health outcome achieved. Results can be categorized as average cost-effectiveness, marginal cost-effectiveness, -
Expected Utility Theory
Expected Utility Theory Simon Grant Timothy Van Zandt Rice University INSEAD 22 November 2007 This is a chapter for the forthcoming Handbook of Rational and Social Choice, Paul Anand, Prasanta Pattanaik, and Clemens Puppe, eds., Oxford University Press, 2008. We review classic normative expected utility theory. Our goal is to frame the subsequent chapters (which consider more modern extensions to and deviations from this classic theory) in a way that is accessible to the non- specialist but also useful to the specialist. We start from scratch with a revealed preference approach to the existence of a utility function. We then present the mathematical structure of additive and linear utility representations and their ax- iomatizations, in the context of abstract choice theory and using intertemporal choice as a source of examples. We are thus able to focus on this mathematical structure without the interference of the specific interpretation and notation for decision under uncertainty. Furthermore, this approach allows us to focus on the interpretation of the axioms when we turn to decision under uncertainty. Contents 1. Introduction 1 2.

Chapter 4 4 Utility
Chapter 4 Utility Preferences - A Reminder x y: x is preferred strictly to y. x y: x and y are equally preferred. x ~ y: x is preferred at least as much as is y. Preferences - A Reminder Completeness: For any two bundles x and y it is always possible to state either that xyx ~ y or that y ~ x. Preferences - A Reminder Reflexivity: Any bundle x is always at least as preferred as itself; iei.e. xxx ~ x. Preferences - A Reminder Transitivity: If x is at least as preferred as y, and y is at least as preferred as z, then x is at least as preferred as z; iei.e. x ~ y and y ~ z x ~ z. Utility Functions A preference relation that is complete, reflexive, transitive and continuous can be represented by a continuous utility function . Continuityyg means that small changes to a consumption bundle cause only small changes to the preference level. Utility Functions A utility function U(x) represents a preference relation ~ if and only if: x’ x” U(x’)>U(x) > U(x”) x’ x” U(x’) < U(x”) x’ x” U(x’) = U(x”). Utility Functions Utility is an ordinal (i.e. ordering) concept. E.g. if U(x) = 6 and U(y) = 2 then bdlibundle x is stri ilctly pref erred to bundle y. But x is not preferred three times as much as is y. Utility Functions & Indiff. Curves Consider the bundles (4,1), (2,3) and (2,2). Suppose (23)(2,3) (41)(4,1) (2, 2). Assiggyn to these bundles any numbers that preserve the preference ordering; e.g. -
Economics, Psychology, and the History of Demand Theory
Economics, Psychology, and the History of Consumer Choice Theory Paper for Conference on The History of Recent Economics (HISRECO) University of Paris X June 22-24, 2007 D.

Earlier versions of this paper were presented at the European Association for Evolutionary Political Economy Conference in Istanbul, Turkey, in November 2006 and at the Whittemore School of Business and Economics, University of New Hampshire, in February 2007. I would like to thank John Davis, Harro Maas, and a number of people in the audience at Istanbul and UNH for helpful comments. 0. Introduction The relationship between psychology and consumer choice theory has been long and tumultuous: a veritable seesaw of estrangement and warm reconciliation. Starting with the British neoclassicism of Jevons and Edgeworth, and moving to contemporary economic theory, it appears that psychology was quite in, then clearly out, and now (possibly) coming back in. If one moves farther back in time and takes the view that the classical tradition was grounded in a natural – and thus non-social, non-mental, and non– psychological – order (Schabas 2005), then the scorecard becomes out, in, out, and (possibly) back in. A tumultuous relationship indeed. The purpose of this paper is to provide a critical examination of this turbulent relationship. The argument is presented in three parts. The first section provides a summary of the standard story about the relationship between psychology and consumer choice theory from the early neoclassicals to the present time. -
The Role of Moral Utility in Decision Making: an Interdisciplinary Framework
Cognitive, Affective, & Behavioral Neuroscience 2008, 8 (4), 390-401 doi:10.3758/CABN.8.4.390 INTERSECTIONS AMONGG PHILOSOPHY, PSYCHOLOGY, AND NEUROSCIENCE The role of moral utility in decision making: An interdisciplinary framework PHILIPPE N.TOBLER University of Cambridge, Cambridge, England ANNEMARIE KALIS Utrecht University, Utrecht, The Netherlands AND TOBIAS KALENSCHER University of Amsterdam, Amsterdam, The Netherlands What decisions should we make? Moral values, rules, and virtues provide standards for morally acceptable decisions, without prescribing how we should reach them. However, moral theories do assume that we are, at least in principle, capable of making the right decisions. Consequently, an empirical investigation of the methods and resources we use for making moral decisions becomes relevant. We consider theoretical parallels of economic decision theory and moral utilitarianism and suggest that moral decision making may tap into mechanisms and pro- cesses that have originally evolved for nonmoral decision making. For example, the computation of reward value occurs through the combination of probability and magnitude; similar computation might also be used for deter- mining utilitarian moral value. Both nonmoral and moral decisions may resort to intuitions and heuristics. Learning mechanisms implicated in the assignment of reward value to stimuli, actions, and outcomes may also enable us to determine moral value and assign it to stimuli, actions, and outcomes. In conclusion, we suggest that moral capa- bilities cancan employemploy andand benefitbenefit fromfrom a varietyvariety of nonmoralnonmoral decision-makingdecision-making andand learninglearning mechanisms.mechanisms.
