66 Effects of Volatility Volatility per se can be bad for economic growth. Volatility per se can be bad for economic growth. Hausmann & Rigobon (2003), Blattman, Hwang, & Williamson (2007), and Poelhekke & van der Ploeg (2007).

8 Econometric findings that oil & other “point-source resources” lead to poor institutions: Isham, Woolcock, Pritchett, & Busby (2005) Sala-I-Martin & Subramanian (2003) Bulte, Damania & Deacon (2005) Mehlum, Moene & Torvik (2006) Arezki & Brückner (2009). The theory is thought to fit Mideastern oil exporters well. 3. Autocratic/Oligarchic Institutions

9 What are poor institutions? A typical list: inequality, corruption, rent-seeking, intermittent dictatorship, ineffective judiciary branch, and lack of constraints to prevent elites & politicians from plundering the country.

10 An example, from economic historians Engerman & Sokoloff (1997, 2000, 2002) Why did industrialization take place in North America, not the South? Lands endowed with extractive industries & plantation crops developed slavery, inequality, dictatorship, and state control, whereas those climates suited to fishing & small farms developed institutions of individualism, democracy, egalitarianism, and capitalism. When the Industrial Revolution came, the latter areas were well-suited to make the most of it. Those that had specialized in extractive industries were not, because society had come to depend on class structure & authoritarianism, rather than on individual incentive and decentralized decision-making.

Anarchic institutions 1. Unsustainably rapid depletion of resources 1. Unsustainably rapid depletion of resources 2. Unenforceable property rights 3. Civil war

1414 The Dutch Disease: The 5 effects elaborated 1) Real appreciation in the currency 1) Real appreciation in the currency taking the form of nominal currency appreciation if the exchange rate floats taking the form of nominal currency appreciation if the exchange rate floats or the form of money inflows, credit & inflation if the exchange rate is fixed; or the form of money inflows, credit & inflation if the exchange rate is fixed; 2) A rise in government spending 2) A rise in government spending in response to availability of tax receipts or royalties. in response to availability of tax receipts or royalties.

1515 The Dutch Disease: 5 side-effects of a commodity boom 3) An increase in nontraded goods prices relative to internationally traded goods 3) An increase in nontraded goods prices relative to internationally traded goods 4) A resultant shift out of non-commodity traded goods, 4) A resultant shift out of non-commodity traded goods, esp. manufactures, esp. manufactures, pulled by the more attractive returns in the export commodity and in non-traded goods. pulled by the more attractive returns in the export commodity and in non-traded goods.

1616 The Dutch Disease: 5 side-effects of a commodity boom 5) A current account deficit, 5) A current account deficit, as booming countries attract capital flows, as booming countries attract capital flows, thereby incurring international debt that is hard to service when the boom ends. thereby incurring international debt that is hard to service when the boom ends. Manzano & Rigobon (2008): the negative Sachs-Warner effect of resources on growth rates during was mediated through international debt incurred when commodity prices were high. Arezki & Brückner (2010a, b): commodity price booms lead to higher government spending, external debt & default risk in autocracies, but do not have those effects in democracies.

17 Summary of channels Five broad categories of hypothesized channels whereby natural resources can lead to poor economic performance: commodity price volatility, crowding out of manufacturing, autocratic institutions, anarchic institutions, and procyclical macroeconomic policy, including capital flows, monetary policy and fiscal policy. But the important question is how to avoid the pitfalls, to achieve resource blessing instead of resource curse.

19 Appendix II: Empirical findings for PPT Simulations of Gold producers: Burkino Faso, Ghana, Mali, South Africa Other commodities: Ethiopia (coffee), Nigeria (oil), S.Africa (platinum) General finding: Under Product Price Targets, their currencies would have depreciated automatically in 1990s when commodity prices declined, perhaps avoiding messy balance of payments crises.

20 Price indices CPI & GDP deflator each include: an international good import good in the CPI, export good in GDP deflator; And the non-traded good, with weights f and (1-f), respectively: cpi = (f)p im +(1-f)p n, p = (f)p x + (1-f) p n.

21 Estimation for each country of weights in national price index on 3 sectors: non tradable goods, leading commodity export, & other tradable goods Argentina is relatively closed; The leading export commodity usually has a higher weight in the country’s PPI than in its CPI, as expected. (Jamaicans don’t eat bauxite.) Mexico is relatively open. “A Comparison of Product Price Targeting and Other Monetary Anchor Options, for Commodity- Exporters in Latin America," Economia, vol.11, 2011 (Brookings), NBER WP A Comparison of Product Price Targeting and Other Monetary Anchor Options, for Commodity- Exporters in Latin America EconomiaBrookings16362

22 In practice, IT proponents agree central banks should not tighten to offset oil price shocks They want focus on core CPI, excluding food & energy. But food & energy ≠ all supply shocks. Use of core CPI sacrifices some credibility: If core CPI is the explicit goal ex ante, the public feels confused. If it is an excuse for missing targets ex post, the public feels tricked. Perhaps for that reason, IT central banks apparently do respond to oil shocks by tightening/appreciating, as the following correlations suggests….

23 The 4 inflation-targeters in Latin America show correlation (currency value in $, import prices in $ ) > 0 ; > correlation before they adopted IT; > correlation shown by non-IT Latin American oil-importing countries.

25 Why is the correlation between the import price and the currency value revealing? The currency of an oil importer should not respond to an increase in the world oil price by appreciating, to the extent that these central banks target core CPI. When these IT currencies respond by appreciating instead, it suggests that the central bank is tightening money to reduce upward pressure on headline CPI.

Producers and consuming countries in grain markets should cooperatively agree to refrain from export controls and price controls. The result would be lower world price volatility. The result would be lower world price volatility.

An initiative that has less merit: 4) Attempts to blame speculation for volatility and so to ban derivatives markets. Yes, speculative bubbles sometimes hit prices. But in commodity markets, prices are more often the signal for fundamentals. Don’t shoot the messenger. Also, derivatives are useful for hedgers.

An example of commodity speculation In the 1955 movie version of East of Eden, the legendary James Dean plays Cal. In the 1955 movie version of East of Eden, the legendary James Dean plays Cal. Like Cain in Genesis, he competes with his brother for the love of his father. Like Cain in Genesis, he competes with his brother for the love of his father. Cal “goes long” in the market for beans, in anticipation of a rise in demand if the US enters WWI. Cal “goes long” in the market for beans, in anticipation of a rise in demand if the US enters WWI.

An example of commodity speculation, cont. Sure enough, the price of beans goes sky high, Cal makes a bundle, and offers it to his father, a moralizing patriarch. Sure enough, the price of beans goes sky high, Cal makes a bundle, and offers it to his father, a moralizing patriarch. But the father is morally offended by Cal’s speculation, not wanting to profit from others’ misfortunes, and tells him he will have to “give the money back.” But the father is morally offended by Cal’s speculation, not wanting to profit from others’ misfortunes, and tells him he will have to “give the money back.”

Cal has been the agent of Adam Smith ’ s famous invisible hand: Cal has been the agent of Adam Smith ’ s famous invisible hand: By betting on his hunch about the future, he has contributed to upward pressure on the price of beans in the present, By betting on his hunch about the future, he has contributed to upward pressure on the price of beans in the present, thereby increasing the supply so that more is available precisely when needed (by the Army). thereby increasing the supply so that more is available precisely when needed (by the Army). The movie even treats us to a scene where Cal watches the beans grow in a farmer’s field, something real-life speculators seldom get to see.

“Resource nationalism” Another motive for commodity export controls: 5) To subsidize downstream industries. E.g., “beneficiation” in South African diamonds But it didn’t make diamond-cutting competitive, and it hurt mining exports. 6) Nationalization of foreign companies Like price controls, it discourages investment.

“Resource nationalism” continued 7) Keeping out foreign companies altogether. But often they have the needed technical expertise. Examples: declining oil production in Mexico & Venezuela. 8) Going around “locking up” resource supplies. China must think that this strategy will protect it in case of a commodity price shock. But global commodity markets are increasingly integrated. If conflict in the Persian Gulf doubles world oil prices, the effect will be pretty much the same for those who buy on the spot market and those who have bilateral arrangements.
