The Middle-Income Trap Turns Ten
Since we introduced the term “middle-income trap” in 2006, it has become popular among policy makers and researchers. In May 2015, a search of Google Scholar returned more than 3,000 articles including the term and about 300 articles with the term in the title. This paper provides a (non-exhaustive) survey of this literature. The paper then discusses what, in retrospect, we missed when we coined the term. Today, based on developments in East Asia, Latin America, and Central Europe during the past decade, we would have paid more attention to demographic factors, entrepreneurship, and external institutional anchors. We would also make it clearer that to us, the term was as much the absence of a satisfactory theory that could inform development policy in middle-income economies as the articulation of a development phenomenon. Three-quarters of the people in the world now live in middle-income economies, but economists have yet to provide a reliable theory of growth to help policy makers navigate the transition from middle- to high-income status. Hybrids of the Solow-Swan and Lucas-Romer models are not unhelpful, but they are poor substitutes for a well-constructed growth framework.
Summary: | Since we introduced the term
“middle-income trap” in 2006, it has become popular among
policy makers and researchers. In May 2015, a search of
Google Scholar returned more than 3,000 articles including
the term and about 300 articles with the term in the title.
This paper provides a (non-exhaustive) survey of this
literature. The paper then discusses what, in retrospect, we
missed when we coined the term. Today, based on
developments in East Asia, Latin America, and Central Europe
during the past decade, we would have paid more attention to
demographic factors, entrepreneurship, and external
institutional anchors. We would also make it clearer that to
us, the term was as much the absence of a satisfactory
theory that could inform development policy in middle-income
economies as the articulation of a development phenomenon.
Three-quarters of the people in the world now live in
middle-income economies, but economists have yet to provide
a reliable theory of growth to help policy makers navigate
the transition from middle- to high-income status. Hybrids
of the Solow-Swan and Lucas-Romer models are not unhelpful,
but they are poor substitutes for a well-constructed growth framework. |
