Learning And Risk Aversion, Carlos Oyarzun, Rajiv Sarin

Carlos Oyarzun

Abstract We study the manner in which learning shapes behavior towards risk when individuals are not assumed to know, or to have beliefs about, probability distributions. In any period, the behavior change induced by learning is assumed to depend on the action chosen and the payoff obtained. We characterize learning processes that, in expected value, increase the probability of choosing the safest (or riskiest) actions and provide sufficient conditions for them to converge, in the long run, to the choices of risk averse (or risk seeking) expected utility maximizers. We provide a learning theoretic motivation for long run risk choices, …

Adaptive Learning In Finitely Repeated Games, Naoki Funai

Naoki Funai

This paper investigates the way in which adaptive players behave in the long-run in finitely repeated games. Each player assigns subjective payoff assessments to his own actions and chooses the action which has the highest assessment at each of his information sets. After receiving payoffs, players update their own assessments of chosen actions using the realized payoffs in an adaptive manner; we consider the updating rules of Watkins and Dayan (1992) and Sarin and Vahid (1999). When players experience random shocks on their assessments, players' behavior strategies converge to a unique agent quantal response equilibrium (McKelvey and Palfrey, 1998) if …

The Smallest Upper Bound For The Pth Absolute Central Moment Of A Class Of Random Variables, Martin Egozcue, Luis Fuentes García, Wing Keung Wong, Ricardas Zitikis

Martin Egozcue

We establish the smallest upper bound for the p absolute central moment over the class of all random variables with values in a compact interval. Numerical values of the bound are calculated for the first ten integer values of p, and its asymptotic behaviour derived when p tends to infinity. In addition, we establish an analogous bound in the case of all symmetric random variables with values in a compact interval. Such results play a role in a number of areas including actuarial science, economics, finance, operations research, and reliability.

An Optimal Strategy For Maximizing The Expected Real- Estate Selling Price: Accept Or Reject An Offer?, Martin Egozcue, Luis Fuentes García, Ricardas Zitikis

Martin Egozcue

Motivated by a real-life situation, we put forward a model and then derive an optimal strategy that maximizes the expected real-estate selling price when one of the only two remaining buyers has already made an offer but the other one is yet to make. Since the seller is not sure whether the other buyer would make a lower or higher offer, and given no recall, the seller needs a strategy to decide whether to accept or reject the first-come offer. The herein derived optimal seller's strategy, which maximizes the expected selling price, is illustrated under several scenarios, such as independent …

Enfoques Teóricos De Las Reglas Por Defecto En El Derecho De Contratos: Complementariedades, Coincidencias Y Contradicciones, Daniel Monroy

Daniel A Monroy C

El artículo muestra una lectura crítica en lo que respecta a la noción, las funciones y el diseño de las reglas por defecto en el derecho de contratos a partir de tres enfoques teóricos a saber: la perspectiva jurídica tradicional; la visión del Análisis Económico del Derecho (AED) en su versión clásica y; el enfoque del denominado behavioral law and economics (BL&E). El documento destaca con particular atención que en lo correspondiente a la noción y las funciones de las reglas por defecto en el derecho de contratos, existe un alto nivel de coherencia entre la perspectiva jurídica tradicional por …

Convex Combinations Of Quadrant Dependent Copulas, Martin Egozcue, Luis Fuentes García, Wing Wong, Ricardas Zitikis

Martin Egozcue

It is well known that quadrant dependent (QD) random variables are also quadrant dependent in expectation (QDE). Recent literature has offered examples rigorously establishing the fact that there are QDE random variables which are not QD. The examples are based on convex combinations of specially chosen QD copulas: one negatively QD and another positively QD. In this paper we establish general results that determine when convex combinations of arbitrary QD copulas give rise to negatively or positively QD/QDE copulas. In addition to being an interesting mathematical exercise, the established results are helpful when modeling insurance and financial portfolios.

Integration–Segregation Decisions Under General Value Functions: ‘Create Your Own Bundle—Choose 1, 2 Or All 3!’, Martin Egozcue, Sebastien Massoni, Wing Wong, Ricardas Zitkiks

Martin Egozcue

Whether to keep products segregated (e.g., unbundled) or integrate some or all of them (e.g., bundle) has been a problem of profound interest in areas such as portfolio theory in finance, risk capital allocations in insurance and marketing of consumer products. Such decisions are inherently complex and depend on factors such as the underlying product values and consumer preferences, the latter being frequently described using value functions, also known as utility functions in economics. In this paper, we develop decision rules for multiple products, which we generally call ‘exposure units’ to naturally cover manifold scenarios spanning well beyond ‘products’. Our …

Mean And Variance Responsive Learning, Carlos Oyarzun, Rajiv Sarin

Carlos Oyarzun

A learning rule is variance-averse if the expected reduced-distribution of payoffs in the next period has a smaller variance than that of the current reduced-distribution, in every set where all the actions provide the same expected payoff. A learning rule is monotonically variance-averse if it is expected to add probability to the set of actions that have the smallest variance in the set, when all the actions have the same expected payoff. A learning rule is monotonically mean-variance-averse if it is expected to add probability to the set of actions that have the highest expected payoff and smallest variance whenever …

Theoretical And Experimental Analysis Of Auctions With Negative Externalities, Youxin Hu, John Kagel, Xiaoshu Xu, Lixin Ye

Youxin Hu

We investigate a private value auction in which a single “entrant” on winning imposes a negative externality on two “regular” bidders. In an English auction, when all bidders are active “regulars” free ride, exiting before price reaches their value. In a first-price sealed-bid auction incentives for free riding and aggressive bidding coexist, limiting free riding. We find substantial, though incomplete, free riding in the clock auction. In first-price auctions, regular bidders bid more aggressively than the “entrant” and both bid higher than in auctions with no externality. Predictions regarding revenue, efficiency, and successful entry between the two auctions are satisfied.

The Role Of The Law In The Availability Of Public Transit And Affordable Housing In Atlanta’S West End, Elliott Lipinsky

ELLIOTT LIPINSKY

The Federal Transit Administration (FTA) is a branch of the U.S. Department of Transportation that administers federal funds and provides technical assistance for the support of locally operated public transit systems. MARTA / Atlanta metro area are part of FTA Region IV (the Southeast). FTA would be involved, for instance, in financing the federal grant monies discussed above. But actual regulation of operations (i.e., what MARTA does each day, or what MARTA will plan to do regionally) is more closely regulated by Georgia agencies.

Until recently, the Atlanta metropolitan area had no powerful central agency to coordinate regional transit. The …

Harnessing Complementarities In The Education Production Function, John A. List, Jeffrey A. Livingston, Susanne Neckermann

Jeffrey A Livingston

Studies which seek to estimate components of the education production function, especially those that employ the “value-added” approach, almost universally assume that the production function is linear and additively separable in its inputs. This strict functional form assumes that there are no complementarities between inputs, though there are compelling intuitive reasons to think they might exist. This study conducts a randomized field experiment to evaluate whether complementarities between students, their parents, and tutors who aid the students in specific subjects can be harnessed using financial incentives. No evidence emerges in support of this hypothesis. The results suggests that a given …

Daily Stock Market Movement From Oscillating Social Mood Factors, Cari Bourette

Cari Bourette

Since 2006, there has been ongoing research into the correlation of a set of oscillating mood factors and socioeconomic, geopolitical, and natural events with the goal of forecasting increased risks of destabilizing events. While promising results have been forthcoming, it has been difficult to present models that allowed those outside a small circle of specialists to participate. Between July 2007 and June 2010, weekly social mood projections, as published in monthly issues of MoodCompass, were used to develop a model to convert four oscillating mood factors into stock market expectations. This model was modified to generate signals of projected stock …

Preferences For Information And Ambiguity, Jian Li

Jian Li

This paper studies intrinsic preferences for information and the link between intrinsic information attitudes and ambiguity attitudes in settings with subjective uncertainty. We enrich the standard dynamic choice model in two dimensions. First, we introduce a novel choice domain that allows preferences to be indexed by the intermediate information, modeled as partitions of the underlying state space. Second, conditional on a given information partition, we allow preferences over state-contingent outcomes to depart from expected utility axioms. In particular we accommodate ambiguity sensitive preferences. We show that aversion to partial information is equivalent to a property of static preferences called Event …

Professor Issam A.W. Mohamed

The purpose of this paper is to present the role of multinational companies in general then its role in Sudan with particular emphasis on oil exploration and extraction. Chinese companies of multinationalities currently control the newly born oil industry in the country. Needless to say that the dire needs of the government because of its international isolation and sanctions compelled it to be subjected to bellow standards conditions in all economic and environmental aspects. The government accepted the conditions for the past twelve years. However, the secession of Southern Sudan into new country gives better re-negotiations opportunity to the newly …

African Economic Blocs And Trade: Case Study Of Comesa And Sudan, Issam A.W. Mohamed Professor

Professor Issam A.W. Mohamed

Comprehensively, Economic Trade Partnerships and Blocs are important to a member country. However, with the continuing global financial distresses it is useful to evaluate them to maximize possible benefit. The question of joining, continue membership with the Comesa is vital to the Sudanese economy that presently stands in a very decisive time. The Common Market for Eastern and Southern Africa is a free trade area with nineteen member states stretching from Libya to Zimbabwe. COMESA formed in December 1994, replacing a Preferential Trade Area which had existed since 1981. Nine of the member states formed a free trade area in …

Review Of The Role Of Agriculture In Sudan Economy, Issam A.W. Mohamed Professor

Professor Issam A.W. Mohamed

The calamities of Sudan expand on daily basis. The secession of Southern Sudan has deprived the country of 25% of it total area, 24% of population, over 80% of its oil income. Moreover, it has separated with 75% of it vegetation cover and 30% of potential arable land. In addition, Sudan stands to tolerate at least 25% of its water resources. Economic situation precarious with the Darfur rebellions, the inception of Southern Kordofan's region civil strive and the inflamed complaints in its Blue Nile region. That resulted besides deprivation of oil revenues and other potentials to increased cost of national …

The paper discusses humanitarian work in Sudan, positive and negative sides. The case study's activities of the Save the Children efforts in Jebel Aulia Internally Displaced People, specially their efforts in education were investigated. It is concluded that introduce invaluable help in educational field, building classes …

Global Financial Crisis And Effects On The Agricultural Sector Of Sudan, Issam A.W. Mohamed Professor

Professor Issam A.W. Mohamed

The severe impacts of the global financial crisis had effects on all world. However, in Sudan scientists and researchers were greatly shocked because of the governmental camouflaging on their real effects on the economy. Minister of National Economy and Finance denied the effects on the Sudanese economy. The governor of the Sudan Central bank did the same with emphasis from both that everything are quite and normal and that Sudan can absorb all shocks on its economic performance. Truly, they ave eaten their words in the following months and confessed the partial effects on the Sudanese economy. Moreover, after they …

Thieves Or Doctors, Armed Civil Conflicts In Darfur And Impacts On Education In Refugees Camps, Professor Issam A.W. Mohamed

Professor Issam A.W. Mohamed

The study presented here depends on a field survey of refugees' camps in war strived Darfur region. The data are genuine from people and children. The expelling of NGOs from the region was a moral shock to the whole world, but in Darfur, it was a humanitarian catastrophe affecting the population. In this paper, I surveyed and analyzed data on what I consider the most important factor which are children and establish education as the base of the arguments introduced here. A case study is introduced which is Attash refugees or displaced camp were produced. Data were collected by field …
