Handbook on Migration and Social Policy

Handbook on Migration and Social Policy

Edited by Gary P. Freeman and Nikola Mirilovic

In this detailed Handbook, an interdisciplinary team of scholars explores the consequences of migration for the social policies of rich welfare states. They test conflicting claims as to the positive and negative effects of different types of migration against the experience of countries in Europe, North America, Australasia, the Middle East and South Asia. The chapters assess arguments as to migration’s impact on the financial, social and political stability of social programs. The volume includes comprehensive reviews of existing scholarship as well as state of the art original empirical analysis.

Chapter 6: Migrant networks, political institutions and international investment

Subjects: politics and public policy, migration, social policy and sociology, comparative social policy, migration, welfare states


The importance of institutional quality for the efficiency of markets has long been recognized by both scholars and policymakers. Transparent institutions provide individuals with information about investment opportunities while credible institutions allow those individuals some measure of confidence that contracts will be honored. This is of significance when engaging in cross-national economic activity, especially when activities such as investment are conducted at arm’s length. But quality institutions do not always exist; sometimes they are difficult or costly to construct, while at other times there are administrative barriers to their creation. Does this mean that countries without transparent and credible institutions will be unable to access global capital markets? Clearly the answer is ‘no’, as even cursory observation reveals that countries with weak institutions – from Azerbaijan to Zimbabwe – receive investments from abroad. This investment occurs because migrant networks – chains of co-ethnics – drive investment from their host countries to their countries of origin. Migrant networks not only serve as a source of information about investment opportunities across national borders, but they also reduce the cost of enforcing international contracts. As such they serve as a substitute for expectation-stabilizing institutions.
