Robert Shiller:
Reviving Real Estate Requires Collective Action, by Robert Shiller, Commentary, NY Times: Imagine that you are watching an outdoor theater production while sitting on the grass. You have difficulty seeing, so you prop yourself up on your knees. Soon everyone behind you does the same. Eventually, most people are kneeling or standing, yet they are less comfortable than they were before and have no better view. Everyone should sit down, and everyone knows it, but no one does.
This is a collective action problem, a phenomenon that is, unfortunately, all too common. At the moment, the trouble in our real estate markets and the drag these markets are placing on our entire economy may be understood as a collective action problem. In a nutshell, mortgage lenders need to write down the amounts owed by individual homeowners — that is, let everyone sit down and relax — but the different stakeholders have been unable to reach an agreement, even if it is in their common interest. ...
If such mortgage principal reductions could be applied on a large scale, there could be large neighborhood effects, raising a sense of optimism among homeowners and bolstering the value of all homes and, ultimately, the whole economy. But mortgage lenders in all their different forms lack a group strategy. ...
He goes on to suggest several solutions to this problem.

The history of the "widely accepted compromise between aggregate prosperity and distributional equality":
The Age of Equality, by Richard Pomfret, Vox EU: Economic reporting in the media frequently appears superficial since important economic processes may take decades for their consequences to work through, whereas media typically need fresh daily or weekly news. Economic history provides an antidote to this rush-to-judgement (e.g. Frindlay and O'Rourke 2008, Eichengreen and Irwin 2009).
It is in this spirit that my new book, The Age of Equality, argues that we are still experiencing the long-term consequences of the industrial revolution of the 1700s, and that the current state of that process involves a widely accepted compromise between aggregate prosperity and distributional equality.
Unlike political revolutions that can be dated to 1789 or 1917, the industrial revolution does not have a precise date. However, by the early 1800s it had clearly taken hold in parts of northwest Europe. The new industrial production involved factories with division of labour (exemplified by Adam Smith's pin factory on the UK's £20 banknotes) which employed increasingly capital-intensive techniques and applied the results of scientific, or at least casual empirical, observation. It was associated with risk-taking entrepreneurs and mobile workers, who responded to price incentives and were rewarded if they made the right decisions. The process was opposed by those enjoying privileges in the pre-industrial economy, e.g. inherited monarchs with absolute power, landowners with serfs or guild members.
Countries adopting the new system enjoyed unprecedented long-term economic growth. They sought and won global markets for their products so that they could expand the division of labour and capital-intensity of their factories, and they established global empires. Success was no secret. The new system spread across Europe, regions settled by Europeans, and a few other places (notably Japan).
Change was resisted by the ancien régime or by imperial rulers. The 1800s were an Age of Liberty because successful economies were those in which people enjoyed sufficient freedom to respond to economic incentives. The pressure to allow such freedom culminated in the 1910s, with the collapse of the great dynastic empires centred in Saint Petersburg, Vienna, Berlin, Constantinople and Peking.
Opposition to unbridled capitalism
Yet, even as living standards increased, opposition to unbridled capitalism strengthened. In all of the high-income countries there is evidence of income inequality peaking around the first decade of the twentieth century.
  • In the US, progressives pushed to reduce the power of the rich by antitrust legislation and to protect the poor by social policies.
  • In Europe, socialists' challenge to capitalism was more fundamental.
The great experiment of the twentieth century was a competition between economic systems over which could best balance prosperity and equality.
The principal challenger was the Soviet centrally planned economy. The success of planning in mass-producing a standardised good was highlighted by the Red Army's successes in 1938-9 against Japan and in the 1941-5 war against Germany. Central planning was also successful in mobilising resources for a specific goal (e.g. sputnik, the first man in space, or winning Olympic medals) and to satisfy basic needs (e.g. housing, education and healthcare).
Central planning was less successful at continuously improving workplace productivity once the initial enthusiasm for Communism or wartime patriotism had ebbed, or in meeting diversified consumer wants once basic needs had been satisfied. Most of all the central planning was hopeless in allocating capital so that diminishing returns were offset by technical change. The clearest statistical indicator of economic failure is the increasing incremental capital-output ratio (i.e how much capital is needed to generate a one unit flow of output) in the Soviet Union from a normal 3-4 in the 1950s to 15 in the early 1980s. By then the economic failure of central planning was obvious to all.
Capitalism's mixed fortunes
The market-based economies experienced mixed fortunes in the first half of the twentieth century. Memories were dominated by the depression of the 1930s, which fuelled demands for reduced inequality. However, Europe enjoyed economic growth over the years 1919-39, and for North America the 1920s were a period of prosperity and innovation.
Henry Ford extended the productivity of the factory system by combining interchangeable parts with the assembly line, bringing down the price of a car to the extent that by 1929 over 23 million cars were in use in the US, for a population of 123 million. Ford, however, lost its premier position in the 1930s to General Motors, which adopted assembly line production and offered a choice of models and colours.
The interwar period also saw the spread of vacuum cleaners, which required novel marketing to convince housewives of their value; of refrigerators, whose value was augmented by Clarence Birdseye patenting an effective frozen food technology, and of washing machines, whose use was increased by the innovation of laundromats. These durable consumer goods were all items that central planning was poor at producing in a range of attractive models accessible to a mass market.
The 1989 watershed
By 1989 the victory of market-based economic system was clear, but the winner was not pure capitalism. Governments intervened not just in the classic roles of supplying law and order and public goods, but also to provide greater equality of opportunity and outcome. In a market economy people are rewarded according to the value of their marginal product, but this is low for the old, the sick, or the handicapped People may lose their source of income for reasons beyond their control, and require time to search for the best new source of income. The children of rich parents get a better start in life through better nutrition, healthcare and education. In all of these areas, governments intervene. The relative focus on equality of outcome and equality of opportunity vary, but the desirability of intervention is no longer a matter of serious disagreement.
On a global scale, the gross inequalities of the early 1900s have been eroded. In the mid-1900s empires were dissolved and modernising governments came to power. Influenced by Soviet success, most regimes adopted economic systems with a heavy state hand, which succeeded initially in mobilising resources, but whose limitations were clear by the 1970s. In the final quarter of the twentieth century, country after country adopted more market-based systems and integrated into the global economy. These emerging economies included some of the world's most populous countries, i.e. China, Mexico, India, Brazil, Indonesia and many more.
Emerging economies: Mixed models
The emerging economies are clearly market-based, but none embraces pure capitalism. Even Hong Kong, the most capitalist economy even while a colony, provided efficient social services and universal public education and healthcare. By the early 2000s, the market economy, and associated pressures for liberty and equality, held undisputed status as the desirable economic system.
This is not the end of history. Debates, rightly, rage in democratic market economies about the appropriate balance between market-driven prosperity and state-mediated equality. In the US the current focus is on healthcare, and in Europe and Australasia on funding for tertiary education. In all countries, aging populations and archaic pension rights pose serious challenges.
At a global level, tensions between established and emerging powers, unlike in 1914-45, cannot be settled by total war. The presence of weapons of mass destruction, cross-border environmental issues and global warming, the responsibility to protect citizens from barbaric governments and the dangers of rogue states all point to the need for international cooperation. The WTO with its almost universally agreed, and abided by, rules for trade despite the lack of serious enforcement mechanisms is an example of imperfect, but functioning, mutually beneficial cooperation. Governance of other multilateral institutions established in the 1940s (the UN, IMF and World Bank) clearly requires reform, while some global and regional problems may require novel institutions. Initiatives like the Svalbard Global Seed Bank, which is supported by regimes as varied as Zimbabwe, North Korea and Syria, provide insurance against inadequate crop biodiversity. The twenty-first century will be the Age of Fraternity because cooperation will be required in the global economy, even though the process may be slow and uneven.
What are the implications for the nearer future? Politicians who rail against socialism or the market always adopt a more moderate stance after they come into office – not because they are cowed by outside forces, but because this is what their electorates want. At any point in time, some voters will be animated by encroachments of the state or by market-generated excesses, but these cannot plausibly be seen as appeals for unfettered capitalism or central planning. The reality is of choices within a narrow band whose limits have been determined by a quarter millennium of economic history.

Elephant populations are becoming increasingly fragmented:

The first of its kind for elephants, the underpass will ideally provide a safe corridor for the large mammals to move throughout the Mount Kenya region (map), where highways, fences, and farmlands have split elephant populations, according to Geoffrey Chege, chief conservation officer of the Lewa Wildlife Conservancy, a Kenya-based nonprofit.
Without the underpass, animals that try to move between isolated areas often destroy fences and crops—leading to conflicts with people.
Since its completion in late 2010, the underpass has been a "tremendous success"—hundreds of elephants have been spotted walking through the corridor...

At first, only adult male elephants ventured through the underpass, and then only at night.
But before long whole family groups were passing through during the day...

Currently the region's elephant populations are divided into two isolated groups: 2,000 animals in Mount Kenya and 7,500 in the Samburu-Laikipia ecosystem, according to the Lewa Wildlife Conservancy.
The elephant underpass ... could improve the genetic health of northern Kenya elephants, since more genes will mix as the animals move into various territories and find new mates.
The corridor may also mean that elephants will move around more, reducing pressure on habitats—and possibly helping other species that use the same resources, such as the black rhinoceros, according to the conservancy. ...

The community service workers we have met here in Kenya are very, very worried about social programs creating dependency on the government. Thus, whenever they talk about their social programs, they emphasize the importance of the individuals "taking ownership."
Obama 050Recess
For example, elementary schools are supposed to be free, but in practice they are not. Parents must buy school uniforms, they must pay teachers extra to get the "full curriculum," there can be development fees for buildings, and so on. In the end, though it's supposed to be free, a substantial number of students are excluded from basic education. The purchase of the school uniform seems to be the biggest barrier (and high school is very expensive for most families, there is tuition in addition to uniforms and other costs, so that most families of limited means cannot afford it).
As another example, Ol Pejeta. the (privately owned) conservancy for endangered animals, helps the communities around it in order to create acceptance for the conservancy (which imposes many costs on the communities). But when they help students, they only pay the fees, they won't pay for uniforms or other costs because, they say, parents must take some degree of ownership (even though this attitude hurts substantial numbers of children who are excluded from the school system). Similar attitudes were applied to maternity care, parents must take some degree of ownership or be excluded, even when it might hurt unborn children.
There are many other examples of this, and there are some examples where "taking ownership" has positive effects. When mosquito nets are given away for free, they end up being used as fishing nets, in chicken coops, all sorts of things that have nothing to do with the intended use. A token payment -- taking ownership -- helps to solve this problem.
So I can understand the fear of dependency in a society such as this, and there is evidence that "taking ownership" can be helpful. But I cannot understand allowing children to be hurt because of it. Sure, there might be a benefit -- some parents will take more interest/ownership in the process. But there is also a cost, many children are excluded from school, and the people paying these costs, the children, are not the ones making the choices. To me, the costs of excluding so many children is far greater than whatever benefit might come from "ownership," and if it were up to me far more resources would be directed toward educating children. It's an investment in the future Kenya will not regret.
