Export diversification through resource-based industrialization: The case of natural gas

For small resource-rich developing economies, specialization in raw exports is usually considered to be detrimental to growth and Resource-Based Industrialization (RBI) is often advocated to promote export diversification. This paper develops a new methodology to assess the performance of these RBI policies. We first formulate an adapted mean-variance portfolio model that explicitly takes into consideration: (i) a technology-based representation of the set of feasible export combinations and (ii) the cost structure of the resource processing industries. Second, we provide a computationally tractable reformulation of the resulting mixed-integer nonlinear optimization problem. Finally, we present an application to the case of natural gas, comparing current and efficient export-oriented industrialization strategies of nine gas-rich developing countries.
