Varieties of Common Sense
Policy officials are often influenced by two broad varieties of conventional wisdom: the set of ideas broadly associated with neoclassical economics; and those ideas flowing from third worldist, anti-imperialist, and structuralist development economics. We show how these apparently opposing perspectives often have a surprising amount in common. Reflexes of ‘impossibilism’ and ‘naive optimism’ are often shared across an ideological divide. Thus, pessimism in orthodox trade theory suggests no African economy can hope to accelerate structural change by defying the signals of comparative advantage; and pessimism in structuralist trade arguments claims limited gains from exporting, especially from exporting primary commodities while the terms of trade are declining. Both forms of pessimism can easily switch to naive optimism when they imagine the ease of rapid and ‘inclusive’ development. But the switch requires that unrealistic conditions are put in place: perfectly competitive markets or idealized South–South cooperation.
