It covers the theoretical channels at stake in the global effect of the networks. It identifies the key issues, namely the impact on size, selection and concentration of the migration flows. The paper also reviews the empirical hurdles that the researchers face in assessing the importance of networks. The key issues concern the choice of micro vs a macro approach, the definition of a network, the access to suitable data and the adoption of econometric methods accounting for the main features of those data. Finally, the paper reports a set of estimation outcomes reflecting the main findings of the macro approach.CC BY 3.0 IGOABUSEADULT POPULATIONARMED CONFLICTARMED CONFLICTSBRAIN DRAINCENSUS DATACENSUSESCITIZENSHIPCIVIL RIGHTSCOMPLICATIONSCOSTS OF MIGRATIONCOUNTRY OF ORIGINCOUNTRY PAIRCOUNTRY PAIRSDEPENDENCEDETERMINANTS OF MIGRATIONDETERMINANTS OF MIGRATION FLOWSDEVELOPING COUNTRIESDEVELOPMENT POLICYDIASPORAECONOMIC BENEFITS FROM IMMIGRATIONECONOMIC MIGRATIONECONOMICS OF IMMIGRATIONEDUCATIONAL ATTAINMENTEMIGRANTSEMIGRATIONEMPIRICAL ANALYSISFAMILY MEMBERSFAMILY REUNIFICATIONFOREIGN DIRECT INVESTMENTHOST COUNTRYHOUSEHOLD LEVELHOUSEHOLDSHOUSINGHUMAN CAPITALIMMIGRANTIMMIGRANT POPULATIONIMMIGRANT STOCKIMMIGRANTSIMMIGRATIONIMMIGRATION POLICYINTERNATIONAL CONVENTIONSINTERNATIONAL MIGRANTSINTERNATIONAL MIGRATIONINTERNATIONAL TRADELABOR FORCELABOR MARKETLEGAL RIGHTSLEVEL OF DEVELOPMENTLEVEL OF EDUCATIONLEVELS OF EDUCATIONMEASUREMENT OF MIGRATIONMIGRANTMIGRANT FLOWSMIGRANT STOCKMIGRANTSMIGRATION COSTSMIGRATION DATAMIGRATION DECISIONSMIGRATION FLOWMIGRATION FLOWSMIGRATION PATTERNSMIGRATION POLICYMIGRATION PROCESSMIGRATION RATESMIGRATIONSMORTALITYMORTALITY RATEMOVEMENT OF PEOPLEMOVEMENTS OF PEOPLENATIONAL BORDERSNATIONAL LEVELNATIONALSNATIVE POPULATIONNET MIGRATIONNUMBER OF MIGRANTSNUMBER OF PEOPLEPEACEPOLICY DISCUSSIONSPOLICY RESEARCHPOLICY RESEARCH WORKING PAPERPOPULATION AND DEVELOPMENTPOPULATION SIZEPOTENTIAL MIGRANTPOTENTIAL MIGRANTSPRIMARY EDUCATIONPROGRESSPUSH FACTORRELIGIONREMITTANCESRESPECTRETURN MIGRATIONROLE OF MIGRATIONSECONDARY EDUCATIONSKILL COMPOSITIONSKILL LEVELSKILL LEVELSSKILLED MIGRANTSSKILLED WORKERSSOCIAL NETWORKSSOCIAL NORMSUNDOCUMENTED MIGRANTSUNDOCUMENTED MIGRATIONWAGE DIFFERENTIALSWARWARSWELFARE STATEWorld Bank10.1596/1813-9450-5721
