Um judiciário independente basta para mitigar a corrupção do próprio poder judiciário?

Não.

Empirical research on the determinants of corruption has made substantial progress over the last decade. To date, the consequences of different structures of the legal enforcement institutions have, however, only played a marginal role. This contribution deals with both the determinants of corruption in the judiciary and the consequences of judicial organization for corruption at large. Regarding the latter, it is shown that the actual independence of the judiciary as well as that of prosecution agencies is correlated with lower levels of corruption. This is also true for a third indicator that measures the degree to which judges are held accountable for their decisions (“judicial accountability”). Furthermore, independence and accountability function as complements in preventing corruption – judicial accountability without independence appears to be ineffective, whereas judicial or prosecutorial independence alone can even have adverse effects. [On the wrong side of the law – Causes and consequences
of a corrupt judiciary,  Stefan Voigt, Jerg Gutmann, International Review of Law and Economics, v.43, 2015, 156-166]

Vejamos as recomendações de política que os autores derivam de seu estudo.

“(…) (1) Make sure that the salaries of judicial personnel remain at least constant in real terms, i.e. insure their certainty, (2) insure that court decision are regularly published, (3) do away with the monopoly of the prosecutor to prosecute criminal acts, (4) reduce the number of independent procedural actions that need to be taken to produce an enforceable court decision and (5) increase the necessity for judges to justify their decisions in legal terms”.

Algorithmic Bias? An Empirical Study of Apparent Gender-Based Discrimination in the Display of STEM Career Ads
Anja Lambrecht , Catherine Tucker

Abstract
We explore data from a field test of how an algorithm delivered ads promoting job opportunities in the science, technology, engineering and math fields. This ad was explicitly intended to be gender neutral in its delivery. Empirically, however, fewer women saw the ad than men. This happened because younger women are a prized demographic and are more expensive to show ads to. An algorithm that simply optimizes cost-effectiveness in ad delivery will deliver ads that were intended to be gender neutral in an apparently discriminatory way, because of crowding out. We show that this empirical regularity extends to other major digital platforms.

Imagino que vá gerar alguma polêmica, mas mostra como o alto valor de certos grupos (demográficos, etc) pode gerar resultados aparentemente contraintuitivos em termos de marketing.

Desigualdade de gênero: as mulheres que fazem turismo sexual, mas não assumem

“(…), gender is also not the only variable at play: women clients are also engaging in sex tourism, as documented both in Thorbek and Pattanaik, and in Taylor (2001). The latter, in particular, offers a more in-depth analysis of North American and Northern European women buying sex work services of young men in the Caribbean, in what they themselves describe as ‘romance holidays’. Responses to her interviews suggest that, on the one hand, women clients are mostly reluctant to define what they engage in as prostitution, and, on the other, that their ideas about the young men whose service they buy are deeply rooted in racist ideas about black men and black men’s sexuality. [DELLA GIUSTA, M. Simulating the impact of regulation changes on the market for prostitution services. European Journal of Law and Economics, v. 29, n. 1, p. 1–14, 2010.]
Pois é. Percebemos, então, que as estatísticas podem ter outra fonte de erros de medida: a dificuldade de mulheres em assumir que estão fazendo turismo sexual. Interessante, né?

Economia da Saúde Neandertal: altruísmo beckeriano ou não?

The most probable evolutionary explanation for apparently ‘selfless’ care ofadult group members lies not only in the benefits of helping relatives but also the selective advantages of reducing the risk of mortality of other group members in situations where groups are highly interdependent (Frank and Linsenmair, 2017). The selective benefits of  are for the ill and injured are clearest where groups consist of close relatives. However where the survival of any one member is strongly linked to that of the others in  the group caring for those who are injured is still selectively advantageous even without a high degree of genetic relatedness.

Living to fight another day: The ecological and evolutionary significance of Neanderthal healthcare
Evidence of care for the ill and injured amongst Neanderthals, inferred through skeletal evidence for survival from severe illness and injury, is widely accepted. However, healthcare practices have been viewed primarily as an example of complex cultural behaviour, often discussed alongside symbolism or mortuary practices. Here we argue that care for the ill and injured is likely to have a long evolutionary history and to have been highly effective in improving health and reducing mortality risks. Healthcare provisioning can thus be understood alongside other collaborative ‘risk pooling’ strategies such as collaborative hunting, food sharing and collaborative parenting. For Neanderthals in particular the selective advantages of healthcare provisioning would have been elevated by a variety of ecological conditions which increased the risk of injury as well their particular behavioural adaptations which affected the benefits of promoting survival from injury and illness. We argue that healthcare provisioning was not only a more significant evolutionary adaptation than has previously been acknowledged, but moreover may also have been essential to Neanderthal occupation at the limits of the North Temperate Zone.

The impact of two different economic systems on dishonesty
DanAriely, XimenaGarcia-Rada, KatrinGödker, LarsHornufde, HeatherManng

Abstract
Using an artefactual field experiment, this paper tests the long-term implications of living in a specific economic system on individual dishonesty. By comparing cheating behaviour across individuals from the former socialist East of Germany with those of the capitalist West of Germany, we examine behavioural differences within a single country. We find long-term implications of living in a specific economic system for individual dishonesty when social interactions are possible: participants with an East German background cheated significantly more on an abstract die-rolling task than those with a West German background, but only when exposed to the enduring system of former West Germany. Moreover, our results indicate that the longer individuals had experienced socialist East Germany, the more likely they were to cheat on the behavioural task.

Como está a tolerância com a liberdade de expressão em nossas universidades?

O sociólogo aí acima é alguém que não vejo muito citado por aqui, por nossos sociólogos de gabinete…ou por nossos jornalistas que, aliás, hoje divulgaram uma suposta tendência à polarização da sociedade brasileira que seria preocupante. Uma tendência ao radicalismo que parece ser o resultado de uma miríade de fatores e, aposto eu, um deles, a falta de hábito de lidar com a diversidade (um hábito muito incentivado por quase 15 anos no país, por gente que pouco tinha (tem) de valores democráticos “em seu DNA”).

Parece-me que, quando você se esforça muito para calar vozes discordantes, uma virada de mesa no jogo do poder faz com que aqueles que sofreram passem a desejar aplicar a mesma repressão aos seus antigos algozes. O rancor gerado não deve ser desprezado…

Mas o início do vídeo me faz pensar no que vejo por aqui. Não é comum ver pessoas com camisas, digamos, do Bolsonaro nas universidades (e quando aparecem, surgem estranhas acusações de fascismo, etc). Será que a liberdade de expressão está sendo respeitada, praticada e incentivada no Brasil? Existe uma pesquisa séria (ou seja, com método científico, dados, aplicação honesta de métodos quantitativos) sobre o tema por aqui?

A propósito, a pesquisa é do Ipsos (mas não encontrei nada no site).

The Announcement Impact of Hosting the FIFA World Cup on Host Country Stock Markets

This study is an investigation of the impact of hosting the FIFA World Cup soccer tournament on the stock market of the host country when the tournament is announced. The sample under examination for this study consists of the 5 FIFA World Cups, between the period 1994 and 2010. Additional factors to be assessed include investigating whether stock markets react efficiently or show a positive reaction to hosting the FIFA World Cup. An event study research methodology is used to investigate the impact of hosting the FIFA World Cup on the stock exchange of the host country, by examining the movement of stock market returns across various event windows during the announcement and tournament starting date stages.

It is found that country stock markets react differently to the announcement of the tournament. For instance South Africa appears to show a positive trend in stock returns at the tournament announcement date, while Japan shows a decline in daily stock returns a day after the announcement of the tournament. It is found that for the tournament announcement, most countries show insignificant negative cumulative abnormal stock returns for different event windows. There are however few instances where country stock markets do show positive cumulative abnormal stock returns, with statistical significant results. The implication of this study is that FIFA World Cups have varied impacts on host country stock markets. This study contributes to the understanding of the impacts of mega sporting events on host country stock markets, with specific reference to the FIFA World Cup.

O segundo é o: Does the World Cup get the economic ball rolling? Evidence from a synthetic control approach

In this paper we analyze the impact of hosting the FIFA Soccer World Cup on GDP per capita in a worldwide sample of countries using a transparent statistical methodology for data-driven case studies ⿿ the synthetic control method. Using country level annual-data covering all events occurring in the period between 1978 (Argentina) and 2006 (Germany), we show that the estimated average treatment effectwas either zero or negative for all but one of the countries analyzed. Our results, therefore, support the general claim that World Cups are not statistically associated to development and economic growth.

Políticas educacionais

Segundo as conclusões deste estudo de 2017 cuja amostra são as escolas públicas brasileiras:

Based on the theoretical propositions and the empirical evidence, educational policies in Brazil should pay special attention to the managerial aspects of school units. In this study, the prominent role of school managers in developing organizational structures to support teaching and learning can be observed in the positive correlation between the level of proficiency in the school’s mathematics and the IME, particularly in schools with the worst levels of proficiency. Therefore, it is extremely important to adapt the existing signaling mechanisms – fluid educational goals instead of goals designed by information at the starting point on proficiency level and a shorter delay in data collection on educational performance, among other things – or to create new mechanisms that act to reduce problems such as moral hazard.

Ah sim, outro resultado interessante é que um diretor de escola, ao atingir a meta de desempenho estabelecida, passa a apresentar esforço marginal decrescente. Nada que não se esperasse…
