TRADE DIVERSIFICATION:<br />

DRIVERS AND IMPACTS<br />

7.1 INTRODUCTION<br />

By Olivier Cadot, Céline Carrère <strong>and</strong> Vanessa Strauss-Kahn<br />

Policy interest in export diversification is not new but, for over two decades, it was<br />

mired in an ideologically loaded debate about the role of the State. Old-time industrial<br />

policy having died of its own excesses, the debate over what, if anything, the government<br />

should do <strong>to</strong> promote export growth was contained within the fringe of the<br />

economics profession. Mainstream economists were happy <strong>to</strong> believe that whatever<br />

market failures were out there, government failures were worse, <strong>and</strong> that anyway most<br />

governments in developing countries lacked the means <strong>to</strong> do anything. But by an<br />

ironic twist of his<strong>to</strong>ry, years of (Washing<strong>to</strong>n-consensus inspired) fiscal <strong>and</strong> monetary<br />

discipline have put a number of developing-country governments back in a position<br />

<strong>to</strong> do something for export promotion, having recovered room <strong>to</strong> manoeuvre in<br />

terms of both external balance <strong>and</strong> budget position. So the question is back.<br />

With limited guidance from theory, the economics profession’s answer <strong>to</strong> the<br />

return of the industrial-policy debate has been <strong>to</strong> go back <strong>to</strong> descriptive statistics (as<br />

opposed <strong>to</strong> the investigation of causal chains). The result is a wealth of new stylized<br />

facts. For instance, surprising patterns of export entrepreneurship have emerged from<br />

the use of increasingly disaggregated data.<br />

One area where theory has proved useful is in the exploration of the linkages<br />

between productivity <strong>and</strong> trade. So-called “new-new” trade models (featuring firm<br />

heterogeneity) have highlighted complex relationships between trade diversification<br />

<strong>and</strong> productivity, with causation running one way at the firm level <strong>and</strong> the other<br />

way around (or both ways) at the aggregate level.<br />

Even at the aggregate level, new issues have appeared. First, Imbs <strong>and</strong> Wacziarg<br />

(2003) uncovered a curious pattern of diversification <strong>and</strong> re-concentration in production,<br />

prompting researchers <strong>to</strong> explore whether the same was true of trade. Second,<br />

a wave of recent empirical work has questioned traditional views on the “natural-re-<br />
