The ends and means of development 29
of many developing countries possess less education and other forms of
specialized human capital than citizens of developed countries, but Olson
points out that most emigrants from these countries to developed coun-
tries typically increase their incomes substantially and immediately. If one
assumes that employers in developed countries generally pay wages refl ect-
ing the marginal product of labour, this implies that these emigrants, even
with their current stock of human capital, are much more productive in
receiving countries than in their home countries. According to Olson,
this is so presumably because of diff erences in the policy and institutional
environments between these countries. In emphasizing the importance of
diff erences in policies and institutions, Olson points to large diff erences
in the growth record of countries during certain periods, despite the fact
that these countries share common cultures and, for long periods of time,
common histories: for example, North and South Korea, East and West
Germany, China, Hong Kong and Taiwan.
More recently, led by the Governance Group at the World Bank, much
more systematic cross-country econometric analyses of the impact of insti-
tutional quality on development outcomes have been undertaken.

The
fi ndings of this empirical perspective can be captured by examining one
particularly infl uential study entitled ‘Governance Matters’, undertaken
by Kaufmann, Kraay and Zoido-Lobaton, all of whom are affi liated with
the World Bank. This regularly updated study is part of the World Bank’s
ongoing research on governance, which now covers about 200 countries.
