New insurance product protects pastoralists from losses due to drought in Kenya

This is rather interesting. Pastoralism is characterized as a complex system of avoiding, accounting for and taking advantage of risk, not unlike hedge fund managers in the United States. Animals represent potential earnings, prices at markets vary with grazing conditions and perceived long term benefits, and decisions to sell animals are not made lightly.

In the past, pastoralists have protected against devastating losses through herd maximization and cooperation and conflict over prime grazing spots, along with systems of redistribution where animals from wealthy herders are given away or stolen with the approval of the community. The world has become complicated, though, as droughts become more and more frequent, political borders and conflicts constrain the movements of pastoralists, and as the spear has been replaced with the AK-47.

An interesting though appropriate insurance system might help to mitigate losses and stabilize communities.

Capital and inequality

Joseph Joyce, professor of economics at Wellesley College wrote and interesting piece to day on capital liberalization and inequality.

I’m glad to see that so much attention is being fawned on Piketty’s most excellent book, “Capital in the 21sr Century.” It’s sure to go down as a classic in the economics literature, but the debate and discussion surrounding the book couldn’t come at a better time.

I don’t think it’s an accident that Piketty’s book, would top the NYT best seller list just a week after appearing, that a sitting President of the US would mention that inequality is one of the most important issues of our time, or that Christine LaGarde, head of the IMF would make a case that we need to address inequality at a global level.

They (Florence Jaumotte, Subir Lall and Chris Papageorgiou) analyzed the effect of financial globalization and trade as well as technology on income inequality in 51 countries over the period of 1981 to 2003. They reported that technology played a larger role in increasing inequality than globalization. But while trade actually reduced inequality through increased exports of agricultural goods from developing countries, foreign direct investment played a different role. Inward FDI (like technology) favored workers with relatively higher skills and education, while outward FDI reduced employment in lower skill sectors. Consequently, the authors concluded, while financial deepening has been associated with higher growth, a disproportionate share of the gains may go to those who already have higher incomes.

This is a scenario we’re all mostly familiar with, though the broad effects are still debatable. Increasing investment by giants like the US in overseas manufacturing push down wages on domestic unskilled labor, but it’s hard to say whether this had a major effect on overall employment. Unemployment remained steady even after Clinton signed NAFTA, and continues to remain well under European levels today, though the lowest level of workers feel the worst pain. I’m not sure if I can really advocate for protectionist measures to keep capital at home or dissuade foreign investment on principle alone, but it is true that the worst effect of foreign competition has been the erosion of labor’s political power.

Jayati Ghosh of Jawaharlal Nehru University of New Delhi has examined the role of capital inflows in developing countries. She maintains that the inflows appreciate the real exchange rate and encourage investment in non-tradable sectors and domestic asset markets. The resulting rise in asset prices pulls funds away from the financing of agriculture and small firms, hurting farmers and workers in traditional sectors. Eventually, the asset bubbles break, and the poor are usually those most vulnerable to the ensuing crisis.

Well, this is somewhat more interesting. Foreign investment in developing countries appreciates the exchange rate, leading domestic investors to put their money into, say, real estate assets. This is certainly the case all over Africa. Land and building developments are occurring at a breakneck pace, with the hopes that expensive properties will be bought up by foreign companies and individuals. It’s certainly the case that no common African could ever afford some of these places (or would even want to buy them if they could). Nairobi, Dar es Salaam and Luanda, Angola are all in the middle of a real estate bubble. The problem, of course, is that domestic investors are hoping to make a quick buck, rather than attempting to create long term, profitable industries. No wonder Africa imports the lion’s share of it’s manufactured goods. No local will invest in the infrastructure to create it locally since urban real estate is so absurdly profitable right now. This, of course, means that money flows directly into the pockets of the urban elite and then sent back out to bank accounts and retailers in France and England, further entrenching the poorest of the poor.

Without the development of local industries, domestic economies can’t function and opportunities for revenue collections are missed. and countries like Tanzania and Kenya, for example, will continue to be beggar economies which depend on the good graces of the international community to support domestic social programs.

Articles I liked 4/12/2014

Here’s a few articles I’ve been reading this morning that I liked.

Intellectual Property Rights, the Pool of Knowledge, and Innovation by Joe Stiglitz (National Bureau of Economic Research)

We began by noting that some observers of innovation have claimed that a more important determinant of the levels of investment in R & D and the pace of
innovation than the intellectual property regime is the “opportunity set,” the knowledge pool from which applied researchers can draw. Knowledge, it is has long been recognized, is a public good—a
common resource from which all can draw (see, e.g., Stiglitz 1987).32 Intellectual property provides a way of appropriating the returns to investments in knowledge, but in doing so, effectively privatizes a public good. But every innovation draws upon prior knowledge, and the boundaries of “new” knowledge are inherently imprecise. Patents inevitably enclose what would otherwise have been in the
public domain. In doing so, not only do they impede the efficient use of knowledge, but because knowledge itself is the most important input into the production of further knowledge (innovations),
they may even impede the flow of innovations.

Democracy does cause growth (National Bureau of Economic Research)

Our baseline results use a linear model for GDP dynamics estimated using either a standard within estimator or various different Generalized Method of Moments estimators, and show that democratizations increase GDP per capita by about 20% in the long run. These results are confirmed when we use a semiparametric propensity score matching estimator to control for GDP dynamics. We also obtain similar results using regional waves of democratizations and reversals to instrument for country democracy. Our results suggest that democracy increases future GDP by encouraging investment, increasing schooling, inducing economic reforms, improving public good provision, and reducing social unrest. We find little support for the view that democracy is a constraint on economic growth for less developed economies.

The Edutainment Industrial Complex (Africa is a country)

So this is their strategy? Ask a bunch of relatively wealthy, globally-mobile pop superstars to tell rural youth to not participate in the flashy urban lifestyle they (the artists) usually promote–to stay in the countryside and participate in the resource extraction side of global capitalism? As Sean pointed out to me over email, the video isn’t unlike the type campaign some dictatorship (South Africa’s racist regime was fond of it) might use as a tool of “national development” or to fight crime or build national morale.

Is this a surprise? Western liberals have long romanticized rural poverty and encouraged Africans to simply do nothing about their developmental problems. Sorry, I had to put on my curmudgeon hat for a while.

Did pathogens influence the course of human development?

I would say “it depends.” I was just reading an interesting article on the “pathogen stress theory” of the development of human societies, most often attributed to Randy Thornhill, an evolutionary biologist at the University of New Mexico.

According to the “pathogen stress theory of values,” the evolutionary case that Thornhill and his colleagues have put forward, our behavioral immune systems—our group responses to local disease threats—play a decisive role in shaping our various political systems, religions, and shared moral views.

If they are right, Thornhill and his colleagues may be on their way to unlocking some of the most stubborn mysteries of human behavior. Their theory may help explain why authoritarian governments tend to persist in certain latitudes while democracies rise in others; why some cultures are xenophobic and others are relatively open to strangers; why certain peoples value equality and individuality while others prize hierarchical structures and strict adherence to tradition. What’s more, their work may offer a clear insight into how societies change.

This is a reasonable view, and something I’ve long observed from working on infectious diseases in developing countries. The developmental trajectory of a country is influenced by the deliberate avoidance of illness. An example can be seen in the locations of African cities. Many African administrative capitals are located on isolated, cool hilltops, far away from rivers and lakes. Colonialists would intentionally set up shop in areas where they were unlikely to encounter malaria.

Developmentally, this has had major implications for trade within Africa. European cities are often placed along water ways amenable to domestic European trade. The lack of trade between African countries is one of the reasons the continent has developed so poorly. This is the direct result of not only colonial priorities of resource extraction to Europe, but also the unfortunate placement of economic centers in response to malaria.

Certainly, the nature of cities themselves have much to do with the control of infectious diseases. Public works often involve the management of sewage waste and the delivery of clean water. Thornhill might suggest that the development of democracy, citizen involvement and taxation to pay for urban improvements are in direct response to enteric diseases.

However, while it is interesting to try to apply this view, it can be taken to the extreme:

Fincher (a graduate student of Thornhill) suspected that many behaviors in collectivist cultures might be masks for behavioral immune responses. To take one key example, collectivist cultures tend to be both more xenophobic and more ethnocentric than individualist cultures. Keeping strangers away might be a valuable defense against foreign pathogens, Fincher thought. And a strong preference for in-group mating might help maintain a community’s hereditary immunities to local disease strains. To test his hypothesis, Fincher set out to see whether places with heavier disease loads also tended toward these sorts of collectivist values.

I’m not sure it’s that easy to boil down political differences between Asia and Europe to a need to manage infectious disease. Certainly, Sweden is more collectivist than England, but I wouldn’t say that their infectious disease profiles are all that different.

Worse yet, if taken to the extreme, this “hunt for significance” will provide one with evidence to support any crazy theory at all. Pathogens exist wherever humans do. Moreover, we risk attributing the contribution of pathogens to human development based on current conditions, assuming that the present is deterministically preordained centuries ago. Until very recently, nearly the entire world was at risk for malaria, but despite this, various societies have embarked on different social and political trajectories.

The biggest problem I have with the theory is in its basic in rational theory. It assumes that humans are making rational choices based on pathogen threats, when we know, and particularly those of us who work in the tropics, that humans often have poor conceptions of disease transmission and causes of illness. At times, despite very obvious threate, humans will act in manners which exacerbate that threat. The history of enteric disease is filled with tales of ignorance and folly.

If we are going to subscribe to a rational model of political and social development which includes pathogens, then we have to also address first, the ability of pathogens to hijack human behavior to create new opportunities for replication and survival and second, that social changes can exacerbate the worst effects of infection. For the first point, I would look to the development of international trade systems which allow pathogens such as influenza to move around the world quickly, increasing opportunities for mutation to avoid immune responses. For the second I would point to polio, a disease which becomes a problem on after the introduction of water sanitation practices.

Thornhill’s ideas are interesting, and certainly provide good material for the popular press and BBQ conversation, but they require that the reader suspend too much consideration of the details of the complex history of human social and political development. Taken with restraint, as in the example of the locations of African cities, they can provide interesting insights into how current conditions are impacted by past pathogenic threats.

I like to think that we are doing better now…..

Every once in a while, you run across something that just gives you the chills.

“A report presented to the World Health Organization (WHO) in 1948 states: “It is not enough to quote that about 3,000,000 deaths are caused yearly by malaria in the world, or that every year about 300,000,000 cases of malaria occur …… that malaria is prevalent in tropical and subtropical areas where food production and agricultural resources are potentially very high, and that, by affecting the mass of rural workers, it decreases their vitality and reduces their working capacity and thus hampers the exploitation of the natural resources of the country. At a time when the world is poor, it seems that control of malaria should be the first aim to achieve in order to increase agricultural output” (WHO, 1948).

Today is World Health Day!

dengueToday, April 7th. is World Health Day, an annual event sponsored by the World Health Organization to help bring attention to pressing public health issues.

This years event focuses on vector borne diseases like dengue fever and Chagas disease, which are transmitted through a third party host such as Aedes mosquitoes or triatomines (kissing bugs).

Both of these diseases are becoming increasingly relevant as the world urbanizes. Dengue and malaria form a complementary nexus of diseases. Malaria is largely associated with rural areas, and rarely found in cities, where dengue fever is almost exclusively found in urban areas. Generally speaking, dengue is a disease of development, where malaria is a disease of the lack of development.

While known to be distributed widely through Latin America and Southeast Asia, dengue has yet to make it on Africa’s radar yet, simply (in my opinion) because not enough people are looking hard enough. Africa, as the most rapidly urbanizing area of the world will eventually face a double burden of dengue and malaria and health facilities aren’t yet prepared to deal with it.

A network visualization of international migration

The UN keeps data on migrations patterns around the world, tracking origin and destination countries and number of migrants (Trends in International Migrant Stock: Migrants by Destination and Origin). I took some time out and created this network visualization of origin and destination countries from 2010. Other years were available, but this is all I had time for.

The size of each node represents the number of countries from which migrants arrive. By far, the most connected country is the United States, accepting more people from more countries than any other place on the planet. Most areas of the network represent geographic regions. Note that Africa is clustered at the top, and pacific island countries are clustered at the bottom.

An interesting result is that countries tend to send migrants to other countries which are only slightly better off than they are. For example, Malawi sends most of its migrants to Zambia and Mozambique, and Zambians go to South Africa, whereas those countries do not reciprocate to countries poorer than them. Wealthy countries tend to be more cosmopolitan in their acceptance of migrants.
