An Empirical Growth Model for Major Oil Exporters

Abstract

SUMMARY This paper develops a long‐run output relation for a major oil‐exporting economy where the oil income‐to‐output ratio remains sufficiently high over a prolonged period. It extends the stochastic growth model developed in Binder and Pesaran (1999) by including oil exports as an additional factor in the capital accumulation process. The paper distinguishes between the two cases where the growth of oil income, go, is less than the natural growth rate (the sum of the population growth, n, and the growth of technical progress, g), and when go ≥ g + n. Under the former, the effects of oil income on the economy's steady growth rate will vanish eventually, while under the latter oil income enters the long‐run output equation with a coefficient which is equal to the share of capital if it is further assumed that the underlying production technology can be represented by a Cobb–Douglas production function. The long‐run theory is tested using quarterly data on nine major oil economies. Overall, the test results support the long‐run theory, with the existence of long‐run relations between real output, foreign output and real oil income established for six of the nine economies considered.

Do Sovereign Wealth Funds Dampen the Negative Effects of Commodity Price Volatility?

“…Moreover, while a commodity price boom increases the physical capital stock, higher volatility of commodity prices signi…cantly reduces it. Therefore, capital accumulation seems to be another important channel through which volatility a¤ects GDP per capita growth; which is in line with what is argued in Gylfason and Zoega (2006) and Esfahani et al (2014) among others.…”

Country-specific oil supply shocks and the global economy: A counterfactual analysis

“…For instance, Esfahani et al (2014), conducting a country-by-country VARX* analysis, investigate the direct e¤ects of oil-revenue shocks on domestic output for nine major oil exporters, of which six are OPEC members (Iran, Kuwait, Libya, Nigeria, Saudi Arabia, and Venezuela), one is a former OPEC member (Indonesia), and the remaining two are OECD oil exporters (Mexico and Norway). 3 Kilian et al (2009) examine the e¤ects of di¤erent types of oil-price shocks on the external balances of net oil exporters/importers.…”
