Piketty’s second law says that if the economy keeps the saving rate, s, constant over time, then the capital-to-income ratio k=y must, in the long run, become equal to s=g… En ... Leer más Leyendo a Piketty: r>g r 1+ g.

Piketty’s research shows that the average rate of return on capital has held at around 4% to 5% for most of human history. This is in that c ti = y Lti + (r – g) w ti I.e. There's Year One, Year Two, and then we would go.

Full disclosure: I have not yet read it. ブログ 暮らし カテゴリーの変更を依頼 記事元: toushiman.com French economist Thomas Piketty caused a sensation in early 2014 with his book on a simple, brutal formula explaining economic inequality: r > g (meaning that return on capital is generally higher than economic growth). Let's see, maybe we can go up to Year, let's go to Year 15 just for good From this history, Piketty derives a grand theory of capital and inequality. that Piketty assigns to r − g has given rise to some confusion, in part because of its familiar presence in the neoclassical growth model, where it is not obviously related to inequality. Piketty's famous ‘fundamental contradiction of capitalism’ r > g would thus be a special case of this inequality when s r = 1, that is, when capitalists accumulate all their income. 率（g）のことです。 資本収益率（r）とは、投資などで得られる収入です。 So we're assuming it's an area where R is greater than G. Now in this column let me write the years. 2014年春に「21世紀の資本」を発売以降、半年で50万部のベストセラーに。 ーー日本でも有名になったフランスの経済学者トマ・ピケティの考え方を特集して、資産運用の必要性を解説していきます。 目次 「21世紀の資本」のポイント 21世紀の資本の秀逸な点は、20カ国以上の国の3世紀にわた … However, strictly speaking, Piketty’s conclusions rest on , not r > g, where s is the s.r > g proportion of capitalists reinvest. 率gを上回る、ということでした。 下の図1を見てもわかるとおり、資本収益率rが時代による変化はあまりなく、4-5％を推移しています。 In fact, if r but s.r < g, capital will grow slower than r > g average income, contrary to Piketty… If this is not so, r needs to be more significantly above g in order for inequality to rise without bound (see also Jakob Kapeller: “The Return of the Rentier” (pdf) ). I When r>g, personal wealth distribution will become more unequal I Growing inequality caused by high sand low g!rising K=Y and =Y I A crisis of overaccumulation? 10 In the Post-Keynesian model, the profit rate Piketty, uses a lots of technical terms and rightly so perhaps, which refer to economics principles of demand and supply, r & g (rate of growth of capital vs growth of economy) at al, and lots of tables and charts. The long-run relationship between r and g has little to do with the fortunes accumulated by Bill Gates and Jeff Bezos. However, Piketty asserts that the elasticity of substitution is more than 1, so that the capital share rises, and r falls less than g. And then Piketty tells us something remarkable: historically, r has almost always exceeded g – but there was an exceptional period in the 20th century, a period of rapid labor force growth and technological progress, when r was less than g. Doch die Zweifel an seinen Thesen wachsen. Here, r is the net rate of profit, which according Piketty is on average at the 5% level (p. 202), although lower values are not excluded in the future.

Thomas Piketty (French: [tɔ.ma pi.kɛ.ti]; born 7 May 1971) is a French economist who is Professor of Economics at the School for Advanced Studies in the Social Sciences (EHESS), Associate Chair at the Paris School of Economics [2] and Centennial Professor of Economics in the International Inequalities Institute at the London School of Economics. So, r > g is really just another way of saying this: Wealth grows faster than the economy. It rose above 5% According to all the reviews of the book, Piketty's fundamental conclusion is that r, the rate of growth of capital, exceeds g, the rate of growth of the economy over the long term. A capital coefficient of, for example, 600% results in a profit share of 30%.
