Illusory correlation in the remuneration of chief executive officers: It pays to play golf, and well

Illusory correlation refers to the use of information in decisions that is uncorrelated with the relevantcriterion. We document illusory correlation in CEO compensation decisions by demonstrating thatinformation, that is uncorrelated with corporate performance, is related to CEO compensation. We usepublicly available data from the USA for the years 1998, 2000, 2002, and 2004 to examine the relationsbetween golf handicaps of CEOs and corporate performance, on the one hand, and CEO compensationand golf handicaps, on the other hand. Although we find no relation between handicap and corporateperformance, we do find a relation between handicap and CEO compensation. In short, golfers earnmore than non-golfers and pay increases with golfing ability. We relate these findings to the difficultiesof judging compensation for CEOs. To overcome this and possibly other illusory correlations inthese kinds of decisions, we recommend the use of explicit, mechanical decision rules.

It's parties that choose electoral systems (or Duverger's Law upside down)

This article presents, discusses and tests the hypothesis that it is the number of parties what can explain the choice of electoral systems, rather than the other way round. Already existing political parties tend to choose electoral systems that, rather than generate new party systems by themselves, will crystallize, consolidate or reinforce previously existing party configurations. A general model develops the argument and presents the concept of 'behavioral-institutional equilibrium' to account for the relation between electoral systems and party systems. The most comprehensive dataset and test of these notions to date, encompassing 219 elections in 87 countries since the 19th century, are presented. The analysis gives strong support to the hypotheses that political party configurations dominated by a few parties tend to establish majority rule electoral systems, while multiparty systems already existed before the introduction of proportional representation. It also offers the new theoretical proposition that strategic party choice of electoral systems leads to a general trend toward proportional representation over time.

It's still 2%: evidence on convergence from 116 years of the US States panel data

A new debate over the speed of convergence in per capita income across economies is going on. Cross sectional estimates support the idea of slow convergence of about two percent per year. Panel data estimates support the idea of fast convergence of five, ten or even twenty percent per year. This paper shows that, if you ``do it right'', even the panel data estimation method yields the result of slow convergence of about two percent per year.

Mastocytose: quand faut-il y penser ? [Mastocytosis: when should it be considered?]

Mast cell disorders are defined by the accumulation of mast cells in one or more organ systems. Cutaneous forms are mainly observed in children whereas systemic forms are predominant in adults. Mast cells cause symptoms by the release of proinflammatory mediators or by infiltration of various organs. The measurement of serum tryptase has opened the possibility of screening for mastocytosis, which must be taken into consideration in case of severe anaphylactic reactions. Definite diagnosis is established based on a biopsy of skin or bone marrow. An activating mutation of stem cell factor receptor c-kit is often found. Treatment is based on control of the symptoms triggered by mast cell degranulation. Moreover, novel treatment options targeting mast cell proliferation become available for clinical use.

Phthalates in the NICU: Is it safe?

AIMS: As growing concerns exist regarding phthalate exposure, which could be teratogenic, carcinogenic or induce reproductive toxicity, we aimed to review the evidence of the risks due to the use of medical devices containing di(2-ethylhexyl)phthalate in hospitalized neonates. METHODS: We reviewed the literature, searching through medical literature databases (Pubmed, MEDLINE, EBM reviews, Cochrane database, Embase and Google Scholar) using the following keywords: phthalate, di(2-ethylhexyl)phthalate, newborn and neonate. RESULTS: We identified several associations with short and long term health dangers, mainly subfertility, broncho-pulmonary dysplasia, necrotising enterocolitis, parenteral nutrition associated cholestasis and neuro-developmental disorders. These data are based mainly on animal or observational human studies. CONCLUSION: Clinicians must be aware of the potential risks due to phthalate exposure in the NICU. Di(2-ethylhexyl)phthalate containing materials should be identified and alternative devices should be considered. There is a need to improve knowledge in this area.

To use it or not to use it: differences between adolescent males carrying a weapon and those using it in a fight

Purpose Data indicate that 19% of male adolescents living in Switzerland carried a weapon in the last 12 months. The main objective of this research is to compare the characteristics of male adolescents carrying a weapon and having used it in a fight from those who have carried but not used it in the previous 12 months. Methods Data were drawn from the 2002 Swiss Multicenter Adolescent Survey on Health (SMASH02) data base, a survey including 7,548[3,710 males] in-school adolescents aged 16-20 years in Switzerland. Only males declaring having carried a weapon (N = 711; 19.2% of the sample) were included in the analysis. Three groups were created: those not having used a weapon (WO; N = 538 subjects), those having used a weapon in a fight once or twice (W12; N = 127), and those having used a weapon in a fight 3 or more times (W3+; N = 46). Multinomial logistic regression was performed to compare the 3 groups on individual, family, school, and social factors using WO as the reference category. Analyses were performed with STATA9. Results are presented as relative risk ratios (RRR). Results W12 males were significantly more likely to perceive their puberty as advanced compared to their peers (RRR: 2.1), to be foreign born (RRR: 2.6), to live in an urban environment (RRR: 1.9), to be in vocational school (RRR: 4.7), to have a poor school connectedness (RRR: 1.8), to skip classes (RRR: 2.1) and to quarrel while intoxicated (RRR: 5.3). W3+ males were significantly more likely to be foreign born (RRR: 3.6) and to live in an urban environment (RRR: 2.4), to be current users of illegal drugs other than cannabis (RRR: 3.8) and to quarrel while intoxicated (RRR: 4.1). No differences were found between groups for tobacco, alcohol, or cannabis use. Conclusions Within a national sample of Swiss youth aged 16-20 years, almost one fifth of male adolescents have carried a weapon in the previous 12 months. Nevertheless, most of them (75.7%) have never used a weapon in a fight. Whether they carry a weapon for defense purposes or as a manly behavior remains to be elucidated. However, urban foreign-born adolescents who quarrel while intoxicated are the most at risk of using a weapon in a fight, and therefore culturally-sensitive prevention approaches need to be developed to decrease violence in this specific population of youth. Having school problems or using illegal drugs other than cannabis seem to differentiate between those who use it in a fight occasionally (once or twice) and those who do it more often.

O poder local em Timor em contexto multicultural

O trabalho que agora se apresenta é fruto, antes de mais, de uma relação especial com Timor. Não necessariamente pela dimensão histórica das várias presenças naquele território mas, e acima de tudo, pela relação pessoal e afectiva com alguns dos responsáveis políticos e religiosos daquele jovem país. Um convite, formulado em 2007 por Xanana Gusmão, levou-nos a calcorrear todo o território num curto espaço de três semanas, corria o Verão de 2008. O objectivo era a análise, no terreno, da viabilidade da instalação de um poder local num país recentemente tornado independente. Timor, fruto da sua história e, muito em especial, das características antropológicas do seu povo, é uma nação assumidamente multicultural. Das origens ancestrais das suas comunidades, dos reinos dispersos que pulverizam o pequeno território, das suas lideranças e dos vários dilectos, associados à longa e marcante presença portuguesa, bem como outras ocupações de países estrangeiros, com destaque para a Indonésia, resulta um caldo cultural, a todos os níveis peculiar. Aqui e acolá ouvimos o povo, entrevistámos e reunimos com os 432 chefes de suco existentes no país, entrevistámos chefes de aldeia e anciãos, reunimos com políticos, sacerdotes, professores e jornalistas. Interpretámos, ou tentámos interpretar, as condicionantes e os cuidados que se devem observar na preparação do quadro jurídico para reger a municipalidade em Timor: as suas vertentes electivas, funcionais, financeiras e fiscalizadoras. Revistámos a História de Timor e passámos por Cabo Verde, país de referência internacional ao nível da sua gestão pública, muito em especial a autárquica. Fizemos, também, óbvia referência à história do poder local em Portugal. Das consultas, do muito que observámos e estudámos, resulta um desinteressado contributo para a implementação do poder local em Timor, com as conclusões que incorporam alertas e sugestões.

O poder local em Timor em contexto multicultural

This study, now on presentation, comes as a result of a special relationship established with East Timor. Not necessarily through the several historical presences in that territory but, above all, through the emotional and personal relationships with some of the political and religious leaders of this young country. An invitation, made in 2007 by Xanana Gusmão, led us throughout the whole territory in a short time of three weeks, running the summer of 2008. Its purpose was the analysis, on the ground, of the possibility of installing local administration in a country which had recently became independent. Timor, as a result of its history, but mostly of the anthropological characteristics of its people, is an openly multicultural nation. The ancestral origins of their communities, its scattered kingdoms that spray along such a small territory, its leaders and many dialects, associated with the long portuguese presence, as well as other occupations made by foreign countries, especially Indonesia, became a cultural melting pot truly unique. Here and there we heard the people and interviewed and met the 432 local elected leaders of the country. We interviewed village elders and meet with politicians, priests, teachers and journalists. We have interpreted, or tried to, the actual conditions and cautions that must be observed in preparing the legal framework to govern the municipality in East Timor: its elective, functional, financial and oversight aspects. We have reviewed Timor’s history and took Cape Verde’s example as an international reference on its public administration, mostly its local authorities. We made also the obvious reference to the portuguese local government’s history. From search, and much of the observed and studied, remains a selfless contribution to the implementation of local government in East Timor, with alerts that incorporate conclusions and suggestions.

Does it cost to be virtuous? The macroeconomic effects of fiscal constraints

We study whether and how fiscal restrictions alter the business cycle features of macrovariables for a sample of 48 US states. We also examine the typical transmission properties of fiscal disturbances and the implied fiscal rules of states with different fiscal restrictions. Fiscal constraints are characterized with a number of indicators. There are similarities in second moments of macrovariables and in the transmission properties of fiscal shocks across states with different fiscal constraints. The cyclical response of expenditure differs in size and sometimes in sign, but heterogeneity within groups makes point estimates statistically insignificant. Creative budget accounting is responsible for the pattern. Implications for the design of fiscal rules and the reform of the Stability and Growth Pact are discussed.
