A Matemática na Ciência Econômica, a Nova Astrologia.

Por que a economia está tão dominada pela matemática, quando economia trata de interações humanas que não são quantificáveis? E quando os modelos matemáticos econômicos erram quase sempre?

Alan Jay Levinovitz escreveu sobre isso definindo a economia matemática como a nova astrologia.

E o estatístico William Briggs comentou esse artigo de Levinovitz em um ótimo texto.

32% dos Adultos Moram com Pais nos EUA. Por que Isso? Qual Será o Resultado disso?


Tem mais adultos (pessoas entre 18 e 34 anos) morando com os pais nos Estados Unidos, do que a percentagem desses adultos casados ou vivendo sozinhos, diz pesquisa da Pew Research. Isso ocorre pela primeira vez na história dos Estados Unidos.

Por que isso ocorre?

Muitas causas, falta de oportunidade de emprego em uma crise não acaba é uma delas, mas também, e deve ser o fator mais importante, tem a falta de valorização cultural do casamento, do relacionamento, do sacrifício pelos filhos. O mundo acha horrível ser casado, ter filhos, viver em casa para a família. O mundo valoriza o sexo casual irresponsável.

Em suma, a principal causa é o egocentrismo da sociedade moderna.

E qual será o resultado de uma sociedade que quer viver às custas dos pais?

No Brasil, foi noticiado recentemente que um jovem de 30 anos quis matar a modelo Ana Hickmann. Esse jovem morava com os pais, e não trabalhava, enquanto o pai fazia bico de porteiro para completar renda.

No Brasil, costuma-se chamar gente desempregada que não estuda nem trabalha e mora com os pais, de grupo "nem-nem". Esse grupo só aumenta no país.

Mas tem muita gente que trabalha, tem dinheiro e ainda foge de relacionamentos e fica no conforto da casa da mãe.

Vejamos o relato da pesquisa nos Estados Unidos:

For First Time in Modern Era, Living With Parents Edges Out Other Living Arrangements for 18- to 34-Year-Olds

Broad demographic shifts in marital status, educational attainment and employment have transformed the way young adults in the U.S. are living, and a new Pew Research Center analysis of census data highlights the implications of these changes for the most basic element of their lives – where they call home. In 2014, for the first time in more than 130 years, adults ages 18 to 34 were slightly more likely to be living in their parents’ home than they were to be living with a spouse or partner in their own household. 1
This turn of events is fueled primarily by the dramatic drop in the share of young Americans who are choosing to settle down romantically before age 35. Dating back to 1880, the most common living arrangement among young adults has been living with a romantic partner, whether a spouse or a significant other. This type of arrangement peaked around 1960, when 62% of the nation’s 18- to 34-year-olds were living with a spouse or partner in their own household, and only one-in-five were living with their parents. 2
By 2014, 31.6% of young adults were living with a spouse or partner in their own household, below the share living in the home of their parent(s) (32.1%). Some 14% of young adults were heading up a household in which they lived alone, were a single parent or lived with one or more roommates. The remaining 22% lived in the home of another family member (such as a grandparent, in-law or sibling), a non-relative, or in group quarters (college dormitories fall into this category).
Young men are now more likely to live with a parent than to live with a spouse or partner; not so for women
It’s worth noting that the overall share of young adults living with their parents was not at a record high in 2014. This arrangement peaked around 1940, when about 35% of the nation’s 18- to 34-year-olds lived with mom and/or dad (compared with 32% in 2014). What has changed, instead, is the relative share adopting different ways of living in early adulthood, with the decline of romantic coupling pushing living at home to the top of a much less uniform list of living arrangements.
Among young adults, living arrangements differ significantly by gender. For men ages 18 to 34, living at home with mom and/or dad has been the dominant living arrangement since 2009. In 2014, 28% of young men were living with a spouse or partner in their own home, while 35% were living in the home of their parent(s). For their part, young women are on the cusp of crossing over this threshold: They are still more likely to be living with a spouse or romantic partner (35%) than they are to be living with their parent(s) (29%). 3
In 2014, more young women (16%) than young men (13%) were heading up a household without a spouse or partner. This is mainly because women are more likely than men to be single parents living with their children. For their part, young men (25%) are more likely than young women (19%) to be living in the home of another family member, a non-relative or in some type of group quarters.
A variety of factors contribute to the long-run increase in the share of young adults living with their parents. The first is the postponement of, if not retreat from, marriage. The median age of first marriage has risen steadily for decades. In addition, a growing share of young adults may be eschewing marriage altogether. A previous Pew Research Center analysis projected that as many as one-in-four of today’s young adults may never marry. While cohabitation has been on the rise, the overall share of young adults either married or living with an unmarried partner has substantially fallen since 1990.
In addition, trends in both employment status and wages have likely contributed to the growing share of young adults who are living in the home of their parent(s), and this is especially true of young men. Employed young men are much less likely to live at home than young men without a job, and employment among young men has fallen significantly in recent decades. The share of young men with jobs peaked around 1960 at 84%. In 2014, only 71% of 18- to 34-year-old men were employed. Similarly with earnings, young men’s wages (after adjusting for inflation) have been on a downward trajectory since 1970 and fell significantly from 2000 to 2010. As wages have fallen, the share of young men living in the home of their parent(s) has risen.
Economic factors seem to explain less of why young adult women are increasingly likely to live at home. Generally, young women have had growing success in the paid labor market since 1960 and hence might increasingly be expected to be able to afford to live independently of their parents. For women, delayed marriage—which is related, in part, to labor market outcomes for men—may explain more of the increase in their living in the family home.
The Great Recession (and modest recovery) has also been associated with an increase in young adults living at home. Initially in the wake of the recession, college enrollments expanded, boosting the ranks of young adults living at home. And given the weak job opportunities facing young adults, living at home was part of the private safety net helping young adults to weather the economic storm.

Educational attainment, race and ethnicity linked to young adult living arrangements

As of 2008 less-educated young adults are more likely to live with a parent than to live with a spouse or partner
Beyond gender, young adults’ living arrangements differ considerably by education and racial and ethnic background—both of which are tied to economic wherewithal. For young adults without a bachelor’s degree, as of 2008 living at home with their parents was more prevalent than living with a romantic partner. By 2014, 36% of 18- to 34-year-olds who had not completed a bachelor’s degree were living with their parent(s) while 27% were living with a spouse or partner. Among college graduates, in 2014 46% were married or living with a partner, and only 19% were living with their parent(s). Young adults with a college degree have fared much betterin the labor market than their less-educated counterparts, which has in turn made it easier to establish their own households.
Among racial and ethnic groups, record-high shares of black and Hispanic young adults (36% for each group) lived in the home of their parent(s) in 2014. By comparison, 30% of white young adults lived at home. White young adults are more likely to be living with a spouse or partner (36%). But the trends are similar for all major racial and ethnic groups including whites: Since 1960 a greater share are living at home and fewer are married or cohabiting and living in their own household.
Since 1940, year when young adult demographic was more likely to live in parent(s)’ home than with spouse or partner
For black young adults, living with mom and/or dad is now the most common arrangement, as only 17% were living with a spouse or romantic partner in 2014. For Hispanic young adults living with parent(s) is also the dominant arrangement as 30% were living with a spouse or significant other in 2014. Generally, young adult blacks and Hispanics lag behind young whites both in terms of educational attainment and employment status.
This report presents the historical trends in the share of young adults who live with their parent(s). The first section presents a simple classification of living arrangements. The second section examines trends in living with parents by demographic and geographic groups. The third section explores the shift away from living with a romantic partner and toward living with parents. The final section examines the relationship between living with parents and trends in the labor market opportunities of young adults.
Other key findings:
• The growing tendency of young adults to live with parents predates the Great Recession. In 1960, 20% of 18- to 34-year-olds lived with mom and/or dad. In 2007, before the recession, 28% lived in their parental home.
• In 2014, 40% of 18- to 34-year-olds who had not completed high school lived with parent(s), the highest rate observed since the 1940 Census when information on educational attainment was first collected.
• Young adults in states in the South Atlantic, West South Central and Pacific United States have recently experienced the highest rates on record of living with parent(s).
• With few exceptions, since 1880 young men across all races and ethnicities have been more likely than young women to live in the home of their parent(s).
• The changing demographic characteristics of young adults—age, racial and ethnic diversity, rising college enrollment—explain little of the increase in living with parent(s).

Pesquisa - Hillary Clinton or Donald Trump? E Obama foi um Sucesso?


Há aquilo que os governos se preocupam e há aquilo que a população se preocupa. Muitas vezes não são coincidentes. No Brasil, o povo deve estar preocupado com o desemprego e a inflação, enquanto o governo quer achar onde pode cortar gastos. Nos Estados Unidos, as pesquisas em geral mostram que o povo americano está preocupado com o desemprego e o terrorismo, enquanto o governo Obama tem mostrado preocupação com mudança climática e banheiros para transgêneros.

A Fox News pegou várias fontes de preocupação do povo americano e perguntou em quem o povo confia para tratar desses temas, Hillary Clinton ou Donald Trump.

Trump ganhou nas duas principais preocupações: economia e terrorismo, enquanto o povo americano acha que Hillary comandará melhor (gastará mais com) saúde, educação e até com imigração e outros tópicos sociais. 

A pesquisa também perguntou sobre o sucesso do governo Obama. Apenas 26% dos americanos acham que estão melhor agora que eram antes de Obama.




Interessante.
