The Lottery Blotto Game

In this paper we relax the Colonel Blotto game assumption that for a given battle the player who allocates the higher measure of resources wins that battle. We assume that for a given battle, the Colonel who allocates the higher measure of resources is more likely to win that battle. We have a simpler model for which we are able to compute all Nash equilibria in pure strategies for any valuations pro le that players might have. Something that is not possible for the original Blotto game. JEL: C72, D74, H56. KEYWORDS: Colonel Blotto game; lottery contest function.

Implantación de un ERP en una compañía de apuestas por Internet

Aquest projecte intenta cobrir les necessitats que genera una empresa nova que vol vendre loteria a Internet. Es necessita tenir ben definits els circuits de compra, de venda, de facturació, de control d'existències, de cobraments i de pagaments, entre d'altres. Per gestionar tota aquesta activitat, s’ha fet servir el ERP Navision amb SQL Server, adaptant-lo i creant noves funcionalitats. L'aplicació Web ha estat integrada amb Navision i s'ha desenvolupat la seva funcionalitat, tenint sessions per a usuari amb comptes propis que permeten la consulta i la compra dels productes que ofereix l'empresa.

The illusion of control, the structures of prizes and the demand for football pools in Spain

Using data for all the fixtures for the seasons from 1972-73 to 2002-03, we estimate a dynamic model of demand for football pools in Spain paying attention to whether their main economic explanatory variable is the effective price of a ticket or the jackpot. Additionally, we evaluate the importance of the composition of the list of games in terms of whether First Division matches are included or not. Results show that the jackpot model is preferred to the effective price model, having important implications in terms of how the structure of the game should be changed in order to increase demand.

Measuring strategic uncertainty in coordination games

This paper explores three aspects of strategic uncertainty: its relation to risk, predictability of behavior and subjective beliefs of players. In a laboratory experiment we measure subjects certainty equivalents for three coordination games and one lottery. Behavior in coordination games is related to risk aversion, experience seeking, and age.From the distribution of certainty equivalents we estimate probabilities for successful coordination in a wide range of games. For many games, success of coordination is predictable with a reasonable error rate. The best response to observed behavior is close to the global-game solution. Comparing choices in coordination games with revealed risk aversion, we estimate subjective probabilities for successful coordination. In games with a low coordination requirement, most subjects underestimate the probability of success. In games with a high coordination requirement, most subjects overestimate this probability. Estimating probabilistic decision models, we show that the quality of predictions can be improved when individual characteristics are taken into account. Subjects behavior is consistent with probabilistic beliefs about the aggregate outcome, but inconsistent with probabilistic beliefs about individual behavior.

The size and distribution of donations: Effects of numbers of potential recipients

Whereas much literature exists on choice overload, little is known about effects of numbers of alternatives in donation decisions. How do these affect both the size and distribution of donations? We hypothesize that donations are affected by the reputation of recipients and increase with their number, albeit at a decreasing rate. Allocations to recipients reflect different concepts of fairness equity and equality. Both may be employed but, since they differ in cognitive and emotional costs, numbers of recipients are important. Using a cognitive (emotional) argument, distributions become more uniform (skewed) as numbers increase. In a survey, respondents indicated how they would donate lottery winnings of 50 Euros. Results indicated that more was donated to NGO s that respondents knew better. Second, total donations increased with the number of recipients albeit at a decreasing rate. Third, distributions of donations became more skewed as numbers increased. We comment on theoretical and practical implications.

In the works of Mar Arza we perceive a sustained concern with lines of writing on surfaces. Earlyon, she altered the pages and letters of old books. More recently she has intervened in the lettersand the blank spaces on all kinds of printed paper — savings books, electricity bills, medical referrals, calendar pages, lottery tickets...

Peña de jugadores de Primitiva y Euromillón

Mitjançant tecnologia JEE, farem una aplicació web segura (https) que ens permetrà gestionar una penya de persones que juga als sortejos de la Primitiva i l'Euromilió. Per una banda, les persones que s'hagin donat d'alta podran, mitjançant pagament previ, escollir amb quin o quins grups de la penya volen participar i gestionar la seva part privada. Per l'altra banda, l'administrador de la web disposarà d'un conjunt de menús que li permetran realitzar la gestió i el manteniment dels penyistes i de les participacions de la penya en els diferents sortejos en què es participi.
