More on the chinese ghost town

Built in a breakneck five years, Kangbashi is a state-of-the-art city full of architectural marvels and sculpture gardens. There's just one thing missing: people. The city, built by the government and funded with coal money, its chief industries energy and carmaking, has been mostly vacant for as long as it has been complete, except for the massive municipal headquarters. It's a grand canyon of empty monoliths. In a paradox only possible in today's economic system, Kangbashi manages to be both a boom town and a ghost town at the same time.

Kangbashi represents a particularly destructive economic force at work in China today: an obsession with GDP that ignores all other metrics of progress or human capital.

Officials (...) say the population reached 50,000 last year, which seems improbable given that pedestrians on the street were outnumbered by street sweepers.

Mao was right: the revolution came from the countryside

If the thesis is correct, much of the recent history of China should be rewritten:

Deng Xiaoping and his supporters, contrary to popular legend, did not agree on a reform program at the Third Plenum of the Eighth Party Congress in 1978, which installed him in power. A Chinese reform official by the name of Bao Tong later admitted as much: “In fact, reform wasn’t discussed. Reform wasn’t listed on the agenda, nor was it mentioned in the work reports.” (...)
Throughout the reform process, the Chinese Communist Party simply reacted to (and wisely did not oppose) bottom-up reform initiatives that emanated largely from the rural population. (...)
Private business originated in agriculture, spread to the cities, and then returned to the countryside as rural-based industry. Many large private manufacturing firms developed in predominantly agricultural provinces (Zhejiang, Shandong, Guangdong, Hunan, and Sichuan).

Droughts, Floods and Financial Distress in the United States

Droughts, Floods and Financial Distress in the United States
John Landon-Lane, Hugh Rockoff, Richard H. Steckel
NBER Working Paper No. 15596*
Issued in December 2009
NBER Program(s): DAE
The relationships among the weather, agricultural markets, and financial markets have long been of interest to economic historians, but relatively little empirical work has been done. We push this literature forward by using modern drought indexes, which are available in detail over a wide area and for long periods of time to perform a battery of tests on the relationship between these indexes and sensitive indicators of financial stress. The drought indexes were devised by climate historians from instrument records and tree rings, and because they are unfamiliar to most economic historians and economists, we briefly describe the methodology. The financial literature in the area can be traced to William Stanley Jevons, who connected his sun spot theory to rainfall patterns. The Dust bowl of the 1930s brought the climate-finance link to the attention of the general public. Here we assemble new evidence to test various hypotheses involving the impact of extreme swings in moisture on financial stress.

I would like to test Mike Davis' thesis that severe droughts in the end of the XIX century put the Brazilian Northeast in a poverty trap.

Ramsey and Kant

Dixit writes about a tale that Samuelson told him:

"On his first day as an undergraduate at Cambridge, Ramsey went to his philosophy tutor Ogden, to discuss some ideas he had about essence and being. After listening, Ogden said, “These notions are rather like those of Kant.” “Kant? Who is he?” “Immanuel Kant was the author of this book I’ll lend you, Kritik der reinen Vernunft.” “But it’s in German, sir, and I don’t know any German.” “That’s all right, I’ll lend you this dictionary.” A couple of weeks later Ramsey came back to Ogden saying “Kant has it almost right, but …” "

The area (Porto) itself is one of the oldest wine-growing regions in the world - officially demarcated back in 1756, a century before Bordeaux.

The new sweet taste and extra kick was an immediate hit with those who could afford it.

Mainstream Plurocracy

I came across the expression "mainstream plurodoxy" while reading this paper by David Colander (hat tip Shikida). I think it quite a neat way to describe modern economics:

By plurodoxy, I mean a mainstream that has no orthodoxy, neoclassical or other. It is a mainstream composed of many different competing beliefs and research programs...
Today, the problem facing all heterodox groups, Austrians included, is that much of what they were fighting against no longer exists, if it ever did exist. Any orthodoxy that may have existed back in the 1970s has been replaced by a mainstream plurocracy.

I think that the concept is a "sequel" of his paper 2000 paper "The Death of Neoclassical Economics"

Economics is easy

Law is hard. Amartya Sen poses the dilemma:

Carla reminds Anne and Bob that she built the darn thing, and no sooner did she finish it than the other two started trying to take it away.

Cofffe and Sugar

Hans-Joachim Voth and Jonathan Hersh estimate that the introduction of coffee and sugar led to a 10% increase in welfare. They say that the stagnant wages before 1800 is a distortion caused by the exclusion of these goods from price indexes. Their method of estimation seems very interesting. Two phrases:

"Half of all spending was on beer and bread, and fully three-quarters of all calories came from these two sources alone."
"The reason why seemingly mundane goods like sugar, coffee and tea made a big difference to living standards is that life was not just “nasty, brutish, and short” at their time of introduction – it was also (in culinary terms) grey, boring, and bland."

"What - or Who - Started the Great Depression?
Lee E. Ohanian

NBER Working Paper No. 15258
Issued in August 2009
NBER Program(s): EFG

---- Abstract -----

Herbert Hoover. I develop a theory of labor market failure for the Great Depression based on Hoover's industrial labor program that provided industry with protection from unions in return for keeping nominal wages fixed. I find that the theory accounts for much of the depth of the Depression and for the asymmetry of the depression across sectors. The theory also can reconcile why deflation and low levels of nominal spending apparently had such large real effects during the 1930s, but not during other periods of significant deflation. "

Latin America's Decline: A Long Historical View

One more paper in my Sisyphean reading list:

by Sebastian Edwards

Abstract:
In this paper I analyze Latin America's very long term economic performance (since the early 18th century), and I compare it with that of the United States, Australia, New Zealand and the countries
of Western Europe. I begin with an analysis of long term data and an attempt at determining when the region's decline really began. The next section deals with the relation between the strength of institutions since colonial rule and the region's economic performance. Next I move to an analysis of Latin America's long history with instability, crises and debt defaults. I show that currency collapses have been a staple of the region's economic history. In the Section that follows I analyze the long term evolution of social conditions, including poverty and income inequality. This analysis shows that a high degree of income disparity and poverty have a long history in the region. The paper ends with an analysis of the way in which Latin American intellectuals and scholars have seen the increasing economic and
income gap with the United States and Canada.

Cooking

No, it was not the division of labour that made us.

Cooked food, by contrast, is easier to digest, gives you more energy, and
takes no time to eat. Cooking also kills bacteria and renders many natural
poisons inactive. So the simple expedient of heating food gave us access to many
more safe calories every day, which was a survival jackpot. Once we started to
eat soft, cooked food, our jaws and teeth were no longer required to munch
ceaselessly, and they became smaller and more delicate. That is why we don't
look like apes anymore. Similarly, the more cooked food we ate, the less
industrial-strength digestion we had to do, and the smaller our guts became. In
the same way that our bodies evolved to better walk on two legs, our bellies
changed to better handle well-done over rare.

European Slaves in Africa

I know that human trafficking was quite common during the poor, nasty, brutish, and long human history. However, this really have surprised me:

"According to one estimate, 7,000 English people were abducted between 1622-1644, many of them ships' crews and passengers. But the corsairs also landed on unguarded beaches, often at night, to snatch the unwary.
Almost all the inhabitants of the village of Baltimore, in Ireland, were captured in 1631, and there were other raids in Devon and Cornwall."

It seems that one million Europeans (an overestimation, some may say) were slaved by North African pirates between 1530 and 1780. More about the subject.

Jorge Luís Borges reads "Del rigor en la ciencia" (On Exactitude in Science) (Via Boing Boing)

In that Empire, the Art of Cartography attained such Perfection that the map of a single Province occupied the entirety of a City, and the map of the Empire, the entirety of a Province. In time, those Unconscionable Maps no longer satisfied, and the Cartographers Guilds struck a Map of the Empire whose size was that of the Empire, and which coincided point for point with it. The following Generations, who were not so fond of the Study of Cartography as their Forebears had been, saw that that vast Map was Useless, and not without some Pitilessness was it, that they delivered it up to the Inclemencies of Sun and Winters. In the Deserts of the West, still today, there are Tattered Ruins of that Map, inhabited by Animals and Beggars; in all the Land there is no other Relic of the Disciplines of Geography.

Borges' short stories give lessons in Methodology . "El rigor..." is a perfect response when somebody criticizes a model for being an abstraction of reality. "Funes, the Memorious" explains why it is dangerous to consider all details of reality or history. Abstraction is a necessity.

Rodrik X Easterly on Industrial Policy and Steady Growth

William Easterly nailed it!

"So here is Dani Rodrik on success and industrial policy: “the countries that have produced steady, long-term growth during the last six decades are those that relied on a different strategy: promoting diversification into manufactured … goods” (cited in Economist’s View).

So Dani concludes, “What matters [for growth in developing countries] is their output of modern industrial goods” and that developing countries will have to get busy with “real industrial policies.” Finally, “external policy actors (for example, the World Trade Organization) will have to be more tolerant of these policies.”

Unfortunately, Dani is also REVERSING CONDITIONAL PROBABILITIES. Dani’s evidence is based on what he believes is the high probability that IF you have had steady growth for six decades, THEN you had industrial policy. This is interesting, but this is not the right probability in deciding whether to choose industrial policy, which is “IF you have industrial policy, THEN what is your chance of steady growth for six decades?”"

"It is the economy, companheiro!": an empirical analysis of Lula's re-election based on municipal data

by Araújo Jr, Carraro, Damé, Shikida and me in the Economics Bulletin

This paper discusses the reasons that led to the Lula's 2006 re-election. Spatial analysis methods revealed that,contrary to 2002, the President had more votes in less developed municipalities of Brazil. The econometric results cast doubt on the analyses that attribute to Bolsa Família Programme total responsibility for the re-election. Lula''s electoral success results from changes in the labor market, low inflation and an export boom that have reduced inequality and
improved the real wages of the Brazilian poor.

Oliver Williamson, Transaction Costs and Dilbert

How useful is anthropometric history?

...Some reflections on Paul Hohenberg’s recent presidential address to the American Economic History Association by John Komlos:

"In his recent presidential address to the American Economic History Association, Paul Hohenberg argued that anthropometric history does not meet his criteria for useful research in the field of economic history. He considers research useful if (a) it “helps shape one of our underlying disciplines”; b) it contributes “to clear—even fresh—thinking about current, policy-related issues or on-going scholarly debates about the historical past"; and c) it “penetrates the fuzzy realm of identity-shaping popular discourse”. I argue briefly that only a superficial reading of the literature would lead to the conclusion that anthropometric history has not been useful."

Obviously I am on Professor Komlos' side. (In fact, I think that Economic History should not try to be useful in any sense. Searching for the truth (or Truth or "truth", you choose) is a mission tough enough.)
