Curiosidade do dia

Via @HelderAMF cheguei a este ensaio "Defending the One Percent" de N. Gregory Mankiw onde encontrei este trecho:

"Joseph Stiglitz’s (2012) book, The Price of Inequality, spends many pages trying to convince the reader that such rent-seeking is a primary driving force behind the growing incomes of the rich. This essay is not the place for a book review, but I can report that I was not convinced. Stiglitz’s narrative relies more on exhortation and anecdote than on systematic evidence. There is no good reason to believe that rent-seeking by the rich is more pervasive today than it was in the 1970s, when the income share of the top 1 percent was much lower than it is today.
.
I am more persuaded by the thesis advanced by Claudia Goldin and Lawrence Katz (2008) in their book The Race between Education and Technology. Goldin and Katz argue that skill-biased technological change continually increases the demand for skilled labor. By itself, this force tends to increase the earnings gap between skilled and unskilled workers, thereby increasing inequality. Society can offset the effect of this demand shift by increasing the supply of skilled labor at an even faster pace, as it did in the 1950s and 1960s. In this case, the earnings gap need not rise and, indeed, can even decline, as in fact occurred. But when the pace of educational advance slows down, as it did in the 1970s, the increasing demand for skilled labor will naturally cause inequality to rise. The story of rising inequality, therefore, is not primarily about politics and rent-seeking but rather about supply and demand.
.
To be sure, Goldin and Katz focus their work on the broad changes in inequality, not on the incomes of the top 1 percent in particular. But it is natural to suspect that similar forces are at work."

Em sintonia com as minhas reflexões:

• "Relações de causa-efeito politicamente correctas mas que não existem"
• "Foi você que pediu mais crescimento à moda antiga?" 

BTW, daqui:

"Há números que ajudam a compreender o percurso da indústria portuguesa de calçado, a investir, em média, 16% do seu valor acrescentado bruto por ano, quase o dobro dos concorrentes Italianos.
...
Sob o lema "A indústria mais sexy da Europa", os sapatos made in Portugal acompanharam a recuperação das exportações com a qualificação dos seus recursos humanos: a percentagem de trabalhadores qualificados subiu de 28% para 48% e o valor acrescentado bruto por trabalhador cresceu 34% em 10 anos."
