Week 1 - Q1

 Explanations Industrial Ecology puzzle

The Industrial Ecology puzzle of my choice is the Natural Resource Curse as described by Richard Auty  for the first time (Auty, 1994). On the question whether a natural resource is beneficial or harmful to an economy, one would intuitively answer that it is beneficial. The reasoning for that is mostly that an natural resource is “free” to an economy, meaning that it can be extracted within the country and can be sold for a relative high price per unit. But when one investigates the answer to this question a little further, one will actually find a negative correlation between natural resources and economic growth.
Numerous papers have been written on this negative correlation, including Jeffrey Sachs and Andrew Warner in 2001. In this paper the following graph is presented:


Figure 1: Growth and natural resource abundance (Sachs & Warner, 2001).

The graph presents the correlation between the export of natural resources as a percentage of the GDP in 1970 and the real economic growth per capita from 1970 to 1989 of the majority of the countries in the world. One can observe a negative trend in the dots that each represent a country, indicating that an increase of the export of natural resources results in a lower real economic growth. It is important to note that a lower growth rate is not the same as a negative growth rate. A lowering growth rate means that the economy is still growing but only using a lower percentage than previous. To me it is interesting to dig deeper in why this may or may not be a causal relation, because at first sight one may never believe that a natural resource might harm the growth of an economy.

First some reasons will be discussed on why this correlation may be a statistical delusion. I will try to argue why this is not the case for the Curse of the Natural Resources. After that I will try to work out three possible explanations: the Dutch disease, the governmental investments and corruption.

There is a possibility that the theory of the Natural Resource Curse, based on the visual representation of the data in the graph above, is in fact based on a fault correlation. First because it can be possible that there is a variable, different from export of natural resources and correlating negatively with economic growth just like the export. This may result in explanations based on the wrong variable and therefore wrong correlation. This statistical fault is called onmitted variable. A way to overcome this, is to control for previous growth rates and variables like climate and geography (Sachs & Warner, 2001). That is exactly what Sachs and Warner did in their statistical analysis that resulted in the graph above. So this will not hold against the statistical phenomenon and it explanations.
Another counterargument for the theory can be the fact that there is no distinction made between the different natural resources, because minerals have very different rents (higher) than agricultural products (Sachs & Warner, 2001). But the worldwide variation in natural resources is mainly caused by the mineral export of countries, so the inclusion of agricultural exports might even lower the observed deviation but in fact it does not alter the basic results from the statistical analysis (Sachs & Warner, 2001).
The final counterargument discussed in this blog is the reasoning that the currently richest countries in the world, used the resources from their colonies to achieve the wealth they experience nowadays (Sachs & Warner, 2001). Two points can be made against that reasoning. First is using the scarce historical data available, the resource intensity ratio until about the 20th century were much lower to ratios nowadays and are therefore incomparable (Sachs & Warner, 2001). Secondly, due to the strong global infrastructure network, relatively inexpensive energy necessary for the development of the industrial sector, cannot be considered to be a limiting for growth because transportation is fast and cheap (Sachs & Warner, 2001).

The first explanation for the correlation in Figure 1 is the Dutch Disease. The name for this phenomenon results from the time the natural gas fields in the north of the Netherlands were discovered (van der Ploeg, 2010). Other countries were interested in buying the Dutch gas, resulting in an increased demand for the Dutch currency, the Guilder (van der Ploeg, 2010). This appreciation resulted in a more expensive Guilder for foreign buyers (van der Ploeg, 2010). For buyers interested in the natural gas it was not considered to be a problem, but for buyers of other Dutch products that did not concern the natural gas (for example Dutch shoes called “klompen”), those products got relatively more expensive (van der Ploeg, 2010). This resulted in a decline of the export of Dutch manufactured products, so a decline of the growth of those sectors (van der Ploeg, 2010).
This story is not only applicable for the Dutch situation, because a situation of increased currency exchange due to discoveries of natural resources, resulting in a decline of the export of non-natural resource related sectors, can happen (and is happening) to other economies as well (van der Ploeg, 2010).  

The second explanation is based on less sustainable investments. Industries that concern the extraction of natural resources usually do not require high skilled employees and/or technologically advanced capital like the manufacturing and service sectors (Gylfason, 2001). Those two latter sectors result in higher sales and profits, resulting in higher economic growth and are therefore more beneficial for the evolution of society (Gylfason, 2001). Both are more sustainable in the lifetime of the capital, considered to be in this case knowledge or so-called “human capital”, compared to the capital of the extraction sector: the natural resource (Gylfason, 2001).
But the “easy-money” made with the natural resources on the short term results in investments and entrepreneurship in the extraction sector, instead of manufacturing and services (Gylfason, 2001). Therefore the economic growth of economies that have a relatively higher share of natural resources in the export is less compared to economies that are more focussed on pro-growth activities in manufacturing and services (Gylfason, 2001).

The third explanation has to do with so called “rent-seeking”. This is a form of activity that does not produce anything but tries to claim the wealth from goods that have weaker property rights, like natural resources (Marotta, 2013). Companies often lobby governments to get a benefit from some public policy, like taxing or spending (Marotta, 2013). Rent seeking does not entail positive social benefits and most of the time the overall effect is even negative (Scholtens, 2004). This phenomenon coheres with prestige projects that do not increase production and therefore social benefits (an example are golden cranes in governmental offices).
Governmental officials are temped for rent-seeking and corruption because profits from natural resources are high, concentrated and mostly easily appropriable (Sachs & Warner, 2001). This will contribute to less pro-growth activities and lower growth.
Research done by Auty (2000) points out the transfer from a development state to a predatory state when a new natural resource is discovered.

My personal thoughts on the theory on the Natural Resource Curse are maybe interesting too to conclude this article on my blog. I have done some research myself on whether the Dutch economy has truly suffered from the Curse. The results of that investigation were not reliable enough to make strong conclusions, but anyhow I believe it can be a good lesson for policy makers. Even though it is a correlation that has not got one outstanding explanation, it is important to take notice of it when the rules and policy around the extraction are created in any country. For example, it will never be harmfull to invest the short term profits made from the extraction, in longer term capital like education and infrastructure. Because whether or not a governmental officer is convinced of the legitimicy of this theory, the improvement of education and infrastructure will increase the personal benefits of every individual in the concerning economy.

2 opmerkingen:

  1. A nice puzzle, interesting as well. I think its rather counterintuitive to think that the real GDP growth declines when the GDP consists of more export of natural resources. You might want to state your sources only at the end of a paragraph instead of every sentence. Reading the source everytime interferes a little with reading. However all these sources do show you've done your research! Other than that I find the article well structured, and it shows three plausible explanations for the Natural Resource Curse

  2. I’ve learnt a lot reading this blog! You seem to have done a lot of research and you found very plausible explanations for a puzzle that seemed inexplicable to me on first sight. It was also very interesting that you devoted a paragraph to all the counterarguments of the theory. One thing that I was curious about still, is the example of the ‘golden cranes in governmental offices’. Maybe you could have referred to a real example, because this example as a possibility seems a bit pulled out of the air to write down the first incredibly decadent thing that comes to mind. All well-structured, as Branco said. And even though it is a long blog post, it is not a drag to read at all, great post!
