On the Size of the Gender Difference in Competitiveness

On the Size of the Gender Difference in Competitiveness. By Silvia Saccardo, Aniela Pietrasz, Uri Gneezy. In Management Science, http://dx.doi.org/10.1287/mnsc.2016.2673

Abstract: We design a new procedure for measuring competitiveness and use it to estimate the magnitude of the gender gap in competitiveness. Before working on a task, participants choose what percentage of their payoffs will be based on a piece-rate compensation scheme; the rest of their payoff is allocated to a competitive compensation scheme. This novel procedure allows us to distinguish between 101 levels of competitiveness, as opposed to the binary measure used in the literature. Whereas the binary measure allows researchers to conclude that about twice as many men as women choose to compete (typically two-thirds versus one-third), the new procedure sheds light on the intensive margin. We find that the intensity of the preference is more extreme than the binary measure could detect. For example, we find that only one-fifth of the most competitive 25% of our participants are women, and the most competitive 10% of our participants are all men. The new procedure also allows us to study the correlation between competitiveness and parameters such as overconfidence, attitudes toward risk, and ambiguity.

Perceived warmth and competence of others shape voluntary deceptive behaviour

Perceived warmth and competence of others shape voluntary deceptive behaviour in a morally relevant setting. Br J Psychol. 2017 Mar 9. doi: 10.1111/bjop.12245. By Azevedo RT, Panasiti MS, Maglio R, Aglioti SM.

Abstract: The temptation to deceive others compares to a moral dilemma: it involves a conflict between the temptation to obtain some benefit and the desire to conform to personal and social moral norms or avoid aversive social consequences. Thus, people might feel different levels of emotional and moral conflict depending on the target of the deception. Here we explored, in a morally relevant setting, how social judgements based on two fundamental dimensions of human social cognition - 'warmth' and 'competence' - impact on the decision to deceive others. Results revealed independent effects for warmth and competence. Specifically, while people are less inclined to deceive for self-gain those individuals they perceive as warm, they also tend to lie more to highly competent others. Furthermore, the perceived warmth and competence modulated the general tendency to reduce deceptive behaviour when there was a risk of disclosure compared to when the lying was anonymous, highlighting the importance of these judgements in social evaluation processes. Together, our results demonstrate that the emotional costs and personal moral standards that inhibit engagement in deceptive behaviour are not stable but rather malleable according to the target and the consequences of the deception.

Do Globalization and Free Markets Drive Obesity among Children and Youth? An Empirical Analysis, 1990–2013

Do Globalization and Free Markets Drive Obesity among Children and Youth? An Empirical Analysis, 1990–2013
http://www.tandfonline.com/doi/abs/10.1080/03050629.2017.1311259?journalCode=gini20&

ABSTRACT: Scholars of public health identify globalization as a major cause of obesity. Free markets are blamed for spreading high calorie, nutrient-poor diets, and sedentary lifestyles across the globe. Global trade and investment agreements apparently curtail government action in the interest of public health. Globalization is also blamed for raising income inequality and social insecurities, which contribute to “obesogenic” environments. Contrary to recent empirical studies, this study demonstrates that globalization and several component parts, such as trade openness, FDI flows, and an index of economic freedom, reduce weight gain and obesity among children and youth, the most likely age cohort to be affected by the past three decades of globalization and attendant lifestyle changes. The results suggest strongly that local-level factors possibly matter much more than do global-level factors for explaining why some people remain thin and others put on weight. The proposition that globalization is homogenizing cultures across the globe in terms of diets and lifestyles is possibly exaggerated. The results support the proposition that globalized countries prioritize health because of the importance of labor productivity and human capital due to heightened market competition, ceteris paribus, even if rising incomes might drive high consumption.

Small association between socioeconomic status and adult fast-food consumption in US

The association between socioeconomic status and adult fast-food consumption in the U.S. By Jay L. Zagorsky , Patricia K. Smith. Economics & Human Biology
http://www.sciencedirect.com/science/article/pii/S1570677X16300363

Highlights
•   Fast-food consumption among adults varies little across SES, measured as income and wealth.
•   Descriptive analyses indicate a weak, inverted U-shaped association between fast-food and SES.
•   Checking nutrition labels frequently and drinking less soda predict less adult fast-food intake.
•    More work hours predict greater fast-food intake.

Abstract: Health follows a socioeconomic status (SES) gradient in developed countries, with disease prevalence falling as SES rises. This pattern is partially attributed to differences in nutritional intake, with the poor eating the least healthy diets. This paper examines whether there is an SES gradient in one specific aspect of nutrition: fast-food consumption. Fast food is generally high in calories and low in nutrients. We use data from the 2008, 2010, and 2012 waves of the National Longitudinal Survey of Youth (NLSY79) to test whether adult fast-food consumption in the United States falls as monetary resources rise (n = 8136). This research uses more recent data than previous fast-food studies and includes a comprehensive measure of wealth in addition to income to measure SES.

Protestant Ethic and Entrepreneurship: Religious Minorities in the Holy Roman Empire

The Protestant Ethic and Entrepreneurship:  Evidence from Religious Minorities in the Former Holy Roman Empire.  By Luca Nunziata, Lorenzo Rocco. European Journal of Political Economy
https://doi.org/10.1016/j.ejpoleco.2017.04.001

Abstract: We investigate the effect of Protestantism versus Catholicism on the decision to become an entrepreneur in former Holy Roman Empire regions. Our research design exploits religious minorities' strong attachment to religious ethic and the predetermined historical determination of religious minorities' geographical distribution in the 1500 s as a result of the “cuius regio eius religio” (whose realm, his religion) rule. We find that today Protestantism increases the probability to be an entrepreneur by around 5 percentage points with respect to Catholicism, a result that survives to a battery of robustness checks. We explicit the assumptions underlying the identification strategy and provide an extensive testing of their validity by making use of several European datasets.

Socially excluded consumers tend to rely on affect to process information, and prefer persuasive messages based on feelings

Speaking to the heart: Social exclusion and reliance on feelings versus reasons in persuasion. By Fang-Chi Lu , Jayati Sinh
http://www.sciencedirect.com/science/article/pii/S1057740817300189.

Abstract: The authors of this study identify an alternative frame of communication for persuading people who feel socially excluded to behave in ways that benefit individual and social well-being, regardless of future connection possibilities. The authors suggest that socially excluded (included) consumers tend to rely on affect (cognition) in processing information, and to consequently prefer persuasive messages based on feelings (reasons). The effect occurs because people tend to ruminate about exclusionary events, which depletes self-regulatory resources. Thus, distraction that interferes with rumination can mitigate the social exclusion effect on affective processing. The authors present findings from five studies across various paradigms promoting personal and social well-being (i.e., donating blood, recycling, and consuming healthful foods) and discuss the theoretical and policy implications.

Expert ability can actually impair the accuracy of expert perception when judging others' performance

Larson, J. S., & Billeter, D. M. (2017). Adaptation and fallibility in experts' judgments of novice performers. Journal of Experimental Psychology: Learning, Memory, and Cognition, 43(2), 271–288. http://dx.doi.org/10.1037/xlm0000304

These authors show that expert ability can actually impair the accuracy of expert perception in the context of judging the performance of others.

They had individuals with a range of singing experience rank-order recordings of different vocalists singing "Let it Go" from best to worst. The true quality of each vocalist was assessed by applying a Bayesian model to the ranking data, and then judgment accuracy was assessed by comparing these "true" rankings to those given by the judges.

Expert singers were less accurate than intermediate singers at determining the relative quality of low-quality vocalists. A subsequent experiment showed that experts notice more mistakes than intermediate or novice judges, and judge these mistakes more harshly.

The authors interpret these results in terms of adaptation level theory, which suggests that people are better able to discriminate at their own adaptation level. Thus, performance expertise increases the ability to discriminate among top performers, but this reduces the ability to discriminate among lower-level performers.

Complex trauma in childhood, a psychiatric diagnosis in adulthood: Making meaning of a double-edged phenomenon

Complex trauma in childhood, a psychiatric diagnosis in adulthood: Making meaning of a double-edged phenomenon. By McCormack, Lynne; Thomson, Sherilyn. In Psychological Trauma: Theory, Research, Practice, and Policy,  Vol 9(2), Mar   2017, 156-165.

Abstract: Objective: No known research explores the double-edged phenomenon of childhood trauma/adult mental health consumer. Therefore, whether receiving a psychiatric diagnosis in light of childhood trauma supports or impedes psychological wellbeing in adult life, is unknown. Method: Interpretative phenomenological analysis (IPA) provided the methodological framework. Data were collected through the use of semistructured interviews. Analysis sought thematic representation from subjective interpretations of the experienced phenomenon: childhood trauma survivor/mental health consumer. Results: Data revealed 1 superordinate theme, Childhood Betrayal, Identity, and Worthiness, that overarched 5 subordinate themes a) legacies, (b) the label, (c) putting the jigsaw together, (d) stigma, and (e) better than good enough self. Legacies of doubt that perpetuated “not good enough” delayed the development of an adult identity of worthiness in these participants. Importantly, the right diagnosis separated self as worthy-adult from self as traumatized child and facilitated positive change for breaking harmful cycles, self-valuing, and increased empathy, wisdom, and patience. Conclusions: Findings inform future research and therapeutic practice in regards to adult help seeking behaviors in light of childhood trauma, often postponed through fear of stigma associated with mental health diagnoses and services. Similarly, findings suggest that ameliorating wellbeing may be dependent on a therapeutic relationship in which accuracy or right fit of diagnosis provides a conduit for the client to disengage from self-blame, unworthiness, and “not good enough.”

Alemania reinventa la crisis energética. Por Holman W. Jenkins, Jr.

ObamaCare no es el único tren en camino de descarrilar que tenemos  ahora. Como Mao apremiando a los campesinos para que fundieran sus cacharros, sartenes y útiles de labranza para convertir a China en un coloso  del acero de la noche a la mañana, Alemania repartía alegremente subsidios para alentar a los ciudadanos y granjeros a instalar  paneles solares y molinos de viento para luego vender la energía  resultante a las compañías eléctricas a precios inflados. El éxito  —Alemania obtiene un 25% de su energía de las renovables— ha  resultado ser un desastre.

Mientras los alemanes se apresuran a hacerse con su dinero fácil, la  producción de dióxido de carbono ha aumentado, no disminuido, porque las compañías, privadas de capital, han pasado a quemar carbón  americano barato para proveer de la necesaria energía cuando el  viento y el sol nos fallan.

Debido a que sol y viento son intermitentes y la red eléctrica está  pobremente preparada para acomodar estas fuentes, los apagones y las  reducciones de suministro amenazan en este invierno.

Como las facturas las pagan hogares y empresas, los precios de la  electricidad son el triple que en los EE UU. Un pánico apremiante es el del empleo, ya que industrias de gran aportación se dirigen a EE UU  para aprovechar la energía barata que ha producido la revolución de  las arenas bituminosas y los esquistos. El máximo responsable  energético de Europa habla ya francamente de la  "desindustrialización de Alemania".

En UK, donde la política pública ha sido casi tan generosa con las  renovables, "Está bien ser muy, muy verde, pero no si estás  interesado en la fabricación", según queja de un prominente CEO.

La gran virtud de la democracia es que no sigue con ciertos planes  hasta el precipicio, pero los mecanismos normales de ajuste están  agarrotados por el hecho de que el desastre energético de Europa  implica al entero espectro político.

Ed Miliband, líder del Partido Laborista de UK, ha fijado el tema de  las elecciones del próximo año cuando prometió recientemente  congelar los precios de la energía si se le elegía. Pero los  laboristas no van a abandonar los subsidios solares y eólicos que  crearon ellos mismos. Quieren dejarlos grabados en piedra, pasando  los costes a las empresas. En Alemania, la conservadora Angela  Merkel se adhirió completamente a las posiciones económicas sobre  energía de la oposición tras Fukushima, dejando a los electores  alarmados sobre los precios de la energía sin lugar al que tornar en  las elecciones de septiembre excepto a Angela Merkel, quien de forma  vaga mostró alguna moderación sobre la energiewende (revolución  energética) que lanzó y continúa liderando.

Un infrecuente destello de raciocinio ha partido en realidad del  probable socio de coalición de Angela Merkel, el SPD, autor de la  ley original sobre energías verdes, cuyo portavoz dice ahora:  "Necesitamos asegurar que la energía renovable es asequible. Y  necesitamos terminar con la idea de que podemos salirnos  simultáneamente de nucleares y el carbón. No va a funcionar."

Es tentador asumir que los políticos europeos eran feligreses de la  iglesia del calentamiento global. Pero más importante es su apego a  la ideología del agotamiento de recursos, que les convenció de haber  elegido un ganador en esta idea porque estaba garantizado que los  precios de los combustibles fósiles harían parecer baratos a los de  la energía verde.

"Cuanta más gente consuma petróleo y carbón, más subirá el precio,  pero cuanta más gente consuma energías renovables, más bajará su  precio", explicó el asesor energético de Angela Merkel.

He aquí una idea que parece ser impermeable a la experiencia y que  es parte del bagaje de todo político que pudiera ser elegido en  nuestro mundo. "Es absolutamente cierto que la demanda [de energías  fósiles] subirá mucho más rápido que el suministro. Ese es un  hecho", explicó el presidente Obama en 2011. Los EE UU "no pueden  permitirse apostar nuestra prosperidad a largo plazo a un recurso  que con el tiempo se agotará."

El Sr. Obama mencionó los fósiles no convencionales exactamente una  vez en su discurso — y solo para decir que también se agotarían.

Si todo esto fuera cierto, Europa no habría llegado a sus presentes  trabajos. Esta es la realidad: la revolución de los fósiles no  convencionales es menos revolucionaria de lo que parece. Ha sacudido  los errores comunes solo porque ha sucedido en las mismas narices de  los americanos, en áreas pobladas en que se asumía que los  "recursos" se habían extraído y transportado hace mucho.

De hecho, los depósitos de hidrocarburos que hay en el mundo son  verdaderamente vastos, incluyendo entre ellos cantidades inimaginables de hidratos de metano . El desafío es el tecnológico y económico de buscar el acceso a un determinado recurso  a un precio asequible — un desafío desde que se usaban trapos para  empaparlos en petróleo de manantiales naturales. Durante ciento  cincuenta años, el precio del barril de petróleo ha fluctuado entre  $10 y $100 (en dólares de 2011), un rango suficiente para encontrar  nuevas reservas cada vez que se quería requerían con objeto de  mantener a los hidrocarburos como fuente de energía de precio  competitivo.

La crisis energética europea es muy parecida a la nuestra de hace 40  años — autoinfligida. El sueño de Europa dejó de ser sostenible al  minuto de que los precios de la energía empezaran a caer en un  competidor comercial importante como los EE UU. LA gran pregunta ahora es cuán lejos irá la secudida política cuando toda la élite está implicada en un insatisfactorio experimento energético, que inevitablemente se ha visto envuelta en el desencanto del público con otro projecto fracasado de la élite, la Unión Europea.

Va a ser fascinante también la suerte de los shales europeos. En Europa, el gobierno, no los propietarios, controla y se beneficia de los recursos minerales, creando la política de suma zero en lo referente a recusos que han hecho al Oriente Medio un parangón de estabilidad y progreso. ¿Y el calentamiento global? Por suerte la respuesta es fácil. Los votantes europeos se van a acercar al punto en que están los americanos, dándose cuenta de que abjurar de la energía barata no hará nada por los niveles de CO2 (y aun menos por el clima) mientras otros no abjuren de la energía barata también.

Germany Reinvents the Energy Crisis
A love affair with renewables brings high prices, potential  blackouts and worries about 'deindustrialization.'
By Holman W. Jenkins, Jr.
http://online.wsj.com/news/articles/SB100014240527023044482045791857 20802195590
Wall Street Journal, Nov. 8, 2013 6:28 p.m. ET

ObamaCare isn't the only policy train wreck in progress. Like Mao  urging peasants to melt down their pots, pans and farm tools to turn  China into a steel-producing superpower overnight, Germany dished  out subsidies to encourage homeowners and farmers to install solar  panels and windmills and sell energy back to the power company at  inflated prices. Success—Germany now gets 25% of its power from  renewables—has turned out to be a disaster.

As Germans rush to grab this easy money, carbon dioxide output has  risen, not fallen, because money-strapped utilities have switched to  burning cheap American coal to provide the necessary standby power  when wind and sun fail.

Because the sun and wind are intermittent and the power grid is  poorly arranged to accommodate them, brownouts and blackouts  threaten this winter.

Because the bills are paid by households and businesses, electricity  rates are triple those in the United States. An immediate panic is  jobs, as prized industries head to the U.S. for cheaper energy  unleashed by the shale revolution. Europe's top energy official now  speaks frankly of the "deindustrialization in Germany."

In Britain, where policy has been nearly as generous to renewables,  "It's fine being very, very green, but not if you're interested in  manufacturing," complains a prominent CEO.

Democracy's great virtue is that it doesn't follow schemes off a  cliff, but the normal adjustment mechanisms are hampered by the fact  that Europe's energy disaster implicates the entire political  spectrum.

Ed Miliband, leader of Britain's Labour Party, set the theme for  next year's British election when he recently promised to freeze  energy prices if elected. But Labour isn't about to disown the solar  and wind subsidies it created. It wants to soldier on, shifting the  cost to business. In Germany, conservative Angela Merkel embraced  the opposition's energy economics wholesale after Fukushima, leaving  voters who are alarmed about energy prices no place to turn in  September's election except Angela Merkel, who vaguely indicated  some moderation of the energiewende (energy revolution) she launched  and continues to champion.

An unwonted glimmer of reason has actually come from Mrs. Merkel's  likely Social Democrat coalition partner, author of Germany's  original green energy law, whose spokesman now says: "We need to  ensure that renewable energy is affordable. And we need to put an  end to the idea that we can pull out of nuclear and coal  simultaneously. This won't work."

It's tempting to assume Europe's politicians were praying in the  church of global warming. But more important is their subscription  to resource-depletion ideology, which convinced them they'd picked a  political winner because rising fossil fuel prices were guaranteed  to make green energy look cheap in comparison.

"When more people consume oil and coal, the price will go up, but  when more people consume renewable energy, the price of it will go  down," explained Ms. Merkel's top energy adviser.

We have here an idea seemingly impervious to experience and part of  the mental baggage of every politician likely to get elected in our  world. "It is absolutely certain that [fossil energy] demand will go  up a lot faster than supply. It's just a fact," President Obama  explained in 2011. The U.S. "cannot afford to bet our long-term  prosperity on a resource that will eventually run out."

Mr. Obama mentioned shale exactly once in his speech—and only to say  shale would run out too.

If all this were true, Europe wouldn't be in its present fix. Here's  the real truth: The shale revolution is less revolutionary than it  seems. It has shocked settled misconceptions only because it  happened under the noses of Americans, in populated areas where the  casual assumption was that "resources" would long ago have been dug  out and carted away.

In fact, the world's store of fossil hydrocarbons is truly vast,  including almost unimaginable quantities of methane hydrates. The  challenge is the technological and economic one of getting access to  a given resource at an affordable price—a challenge ever since men  used rags to soak up oil from natural seeps. For 150 years, the  price of a barrel of oil has fluctuated between $10 and $100 (in  2011 dollars), a range that has been sufficient to call forth new  reserves and feedstocks whenever needed to maintain hydrocarbons as  a source of competitively priced energy.

Europe's energy crisis is a lot like ours of 40 years ago—self- inflicted. Europe's dream was untenable the minute energy prices  began falling in a major trade competitor like the United States.  The big question now is how far will the political upheaval go when  an entire elite is implicated in an unsatisfactory energy  experiment, which inevitably has become wrapped up in public  disappointment with another failed elite project, the European Union  itself.

Fascinating too will be the fate of Europe's shale. In Europe,  government, not landowners, controls and benefits from mineral  resources, creating the zero-sum resource politics that have made  the Mideast a paragon of stability and civil progress. What about  global warming? At least that answer is easier. European voters are  coming out where Americans have, realizing that foreswearing cheap  energy will do nothing for CO2 levels (and even less for climate) as  long as others aren't foreswearing cheap energy too.
