长期停滞之外

Sep 5, 2018 Joseph E. Stiglitz

纽约—拉里·萨默斯（Larry Summers）正确地指出，“长期停滞”一词从二战临近结束时开始流行。阿尔文·汉森（Alvin Hansen，以及其他很多人）担心，失去了战争所提供的刺激，经济将回归衰退或萧条。看起来，经济存在一种根本性的顽疾。

但这并没有发生。汉森等人为什么错得如此离谱？和某些当代长期停滞鼓吹者一样，其基础微观和宏观经济学分析存在深刻的漏洞——最重要的是，对大萧条根源本身的分析也存在深刻漏洞。

布鲁斯·格林瓦尔德（ruce Greenwald ）和我（与我们的合作者一起）指出，光是在大萧条的前三年，农业生产率高增长（再加上全球高产出）压低了农作物价格——有时高达75%。美国主要经济部门收入降低了大约一半。农业危机导致了城市商品需求的下降，从而引发整个经济的衰退。

The bottom line seems to be that both Summers and Stiglitz agree that a much larger stimulus would, in retrospect, have been much better, and that although the design of the stimulus matters, even an unbalanced one like Trump's tax cut can do a lot of good. Their difference seems to be over the political possibilities of enacting a larger stimulus. Why that's even in question is mystifying, as clearly the radical Republicans, soon to take over the party altogether, were strongly opposed to doing anything much at all. I personally thought it was a near-miracle that any stimulus at all took place.

Not a word about how oil prices caused the great recession.

The first portion of your column is intriguing in its analysis of powerful underlying social movements and their impact on the economy. We have heard that WWII was the great Keynesian stimulus program that wrenched the U.S. out of the Great Depression. The social, economic impact of the war moving masses of people from the rural economy to an urban, factory oriented economy exists outside of the standard Keynesian economic model. I agree with you regarding the lack of a well-designed stimulus program after the financial crisis of 2008. However, I'm not sure that running a $1.5 trillion deficit at a record-breaking 10% of GDP is a lackluster response from a Keynesian perspective, but the spending did little to invigorate the economy. The financial collapse coincided with the denoument of both the baby boom generation's participation in the work force, and its rabid hunger for credit which started in the early 1980s with the rapid proliferation of credit cards, mortgage refinancing and home equity loans. It is hard to say what combination of Keynesian policies would have made a difference, given that the fiscal multiplier was well below one.

“But what was predictable and predicted was the manner in which under-regulated derivatives could inflame the crisis” Not true!

What should have been predictable is that if you allowed banks to leverage 62.5 times with assets only because a human fallible rating agency had assigned these an AAA to AA rating, something had to end up very bad.

I just tweeted a response to this article with the following header:

“Trust the #EcoIsOurs narrative of the #TheWorldIsFlat4GD" 3 shared images of "Confíen en la narrativa EcoSiNuestra del mundo globalizado plano ( https://medium.com/@gmh_upsa/conf%C3%ADen-en-la-narrativa-ecosinuestra-del-mundo-globalizado-plano-b637cfbbffa1 … )" is meant to be the response to "Beyond Secular Stagnation by @JosephEStiglitz (http://prosyn.org/OsuGcra )."

The first image says in its first column:

Please consider the companion image “Trust the #EcoIsOurs (all hashtags are emerging knowledge flows) narrative of the #TheWorldIsFlat4GD,” which is a translation of the introductory image of the Medium post “Confíen en la narrativa EcoSiNuestra del mundo globalizado plano:”

-- There must be no trust on EcoNoMy science as the essential lessons to avoid a global downturn are now those of the #EcoIsOurs profession.

-- This responds Joseph Stiglistz, who says that “There is no reason economists should agree about what is politically possible,” in an article mentioned in the second column of this image.

And in its second column

Under his Sep 5, 2018, Project Syndicate article “Beyond Secular Stagnation,” JOSEPH E. STIGLITZ, said that:

-- Here are the essentials: We would have had a stronger recovery if we had had a bigger and better-designed stimulus. We would have had stronger aggregate demand if we had done more to address inequality, and if we had not pursued policies that increased it. And we would have had a more stable financial sector if we had regulated it better.

-- These are the lessons that we should keep in mind as we prepare for the next economic downturn.

The second image says:

Translation. As a self-appointed #GlobalDebout Trust Counsel, I suggest you trust the #EcoIsOurs narrative of #TheWorldIsFlat4GD we need. It would be to create, with institutional innovations, the #SystemicCivilization that, at the beginning, will stimulate exponential learning opportunities to approach the perfect with the #GreatCapitalism in favor of the great majorities. This is how the North Star of the #BrightGlobalization #BG_NS will follow the Updated Global Conceptual Model #MCGA.

Insisting that the developing countries follow efficiently, with for example fiscal reforms, the course of the developed, previously united as the West, I suggest Not to trust the institutions that continue to protect industrial civilization. Do not trust the World Bank, the IMF, the United Nations, which transferred the national power to globalized power, with unsustainable neoliberal regulations that impede the institutional innovation that we now recognize as legalized corruption that is protected by the Simplistic Globalization Model #MSG that supports all kind of false news. These are narratives of good capitalism that favors minorities, enemy of the perfect for others, both that of Margaret Thatcher that There is No Alternative to Neoliberalism, and that of the Washington Consensus that have degenerated with the passage of time into the #DarkGlobalization and in the #DeGlobalization.

That third column is in Spanish and can be seen in the link of the Medium post on the header of the above mentioned tweet heather.
