Research notes
Published papers on trade, finance, migration and knowledge whose replication data sits in a public archive. Each note states the question the authors asked, what they found, and what this platform's own data can add to it — including, where it applies, that it can add nothing.
Does money earned abroad build anything lasting at home?
Gaurav Khanna et al. (2026) · Review of Economic Studies
Khanna, Murathanoglu, Theoharides and Yang use the 1997 Asian Financial Crisis, which moved exchange rates differently for Philippine provinces depending on...
MigrationWhat happens when the arrivals are near-perfect substitutes for the workers already there?
Sebastian Braun, Toman Omar Mahmoud (2014) · Journal of Economic History 74(1)
Braun and Mahmoud use the same expellee episode for a different question. Because expellees were ethnic Germans, not selected on skills or job prospects,...
MigrationIf you shut a border to protect domestic workers, do their wages actually rise?
Michael A. Clemens, Ethan G. Lewis, Hannah M. Postel (2018) · American Economic Review 108(6)
Clemens, Lewis and Postel study the 1964 exclusion of nearly half a million Mexican bracero farm workers from the United States, a policy explicitly...
MigrationIf firms cannot hire foreign workers for low-skill jobs, do they hire local ones instead?
Michael A. Clemens, Ethan G. Lewis (2026) · American Economic Journal: Applied Economics
Clemens and Lewis exploit the randomised lottery that allocates part of the US H-2B visa quota — as clean an experiment as this literature gets. Firms that...
MigrationHow long does a labour market take to absorb a very large, sudden arrival?
Sebastian Till Braun, Henning Weber (2021) · Journal of International Economics
Braun and Weber study the arrival of eight million German expellees in West Germany after 1945, distributed very unevenly between regions. Fitting a dynamic...
MigrationDoes money sent home protect households from bad years, or add another source of instability?
Catalina Amuedo-Dorantes, Susan Pozo (2011) · American Economic Review 101(3)
Amuedo-Dorantes and Pozo examine Mexican household data from 2000 to 2008, correcting for the reverse causality that makes this hard — households in trouble...
MigrationDo people who flee do as well in a new labour market as people who choose to move?
Courtney Brell, Christian Dustmann, Ian Preston (2020) · Journal of Economic Perspectives 34(1)
Brell, Dustmann and Preston survey refugee labour-market outcomes across high-income countries and find refugees do persistently worse than economic...
MigrationWhen seven million people arrive at once, who gains and who loses?
Lorenzo Caliendo et al. (2023) · AEA Papers and Proceedings
Caliendo, Opromolla, Parro and Sforza treat the arrival of more than seven million Ukrainian refugees after the 2022 invasion as an exogenous,...
MigrationWhy has the wage gap between immigrants and natives widened for each successive arrival cohort?
Christoph Albert, Albrecht Glitz, Joan Llull (2026) · American Economic Review
Albert, Glitz and Llull show that immigrant wage assimilation depends not only on individual skill accumulation but on labour market equilibrium. When...
MigrationDoes a hotter year send people abroad, and does it matter whether they have relatives already there?
Ana María Ibáñez et al. (2026) · Journal of Development Economics
Ibáñez, Quigua, Romero and Velásquez show that exposure to extreme temperatures raises international migration from El Salvador. The chain is specific: heat...
MigrationHow much of what migrants send home does anybody actually observe?
Giuseppe De Arcangelis et al. (2022) · Journal of Development Economics
De Arcangelis, Fertig, Liang, Srouji and Yang tackle the measurement problem directly, comparing survey responses against administrative records and a...
MigrationIf cities pay so much more, why do so few people move to them?
Travis Baseler (2023) · American Economic Journal: Applied Economics 15(4)
Baseler runs two field experiments in Kenya and finds part of the answer is that rural households do not know how much migrants earn. Parents underestimate...
Where a note says the data is behind a login, that is openICPSR, which refuses non-browser requests. Those notes rest on the published abstract and on our own observations, never on files we could not open.
