Temporary migration reshapes EU economies, policy trade-offs
A new ECB working paper finds that temporary migration significantly alters macroeconomic fluctuations and the effectiveness of stabilization policies in integrated economies like the European Union. Labour mobility redistributes shock impacts and modifies policy trade-offs across regions.
Migration's triple impact on economic adjustment
The study, using a two-country DSGE model, reveals that temporary migration acts as a powerful, yet non-neutral, adjustment mechanism in integrated economies.
First, it redistributes the impact of productivity shocks across regions, smoothing output fluctuations in receiving economies while having more varied effects in sending economies.
Second, labour mobility favorably alters policy trade-offs: it reduces the output costs associated with monetary tightening and mitigates the crowding-out effects typically seen during fiscal expansions.
Third, migration strengthens cross-country spillovers by transmitting labour market shocks between regions and reshaping their domestic propagation.
These findings highlight that migration decisions, driven by labour market conditions and exchange rate movements, are a crucial channel for cross-country adjustment.
The analysis compares scenarios with open and closed borders to isolate migration's macroeconomic role, emphasizing its endogenous response to economic conditions.
Modelling cross-border labour dynamics
The paper is motivated by the substantial increase in cross-border labour flows within the European Union, particularly following the 2004 and 2007 enlargements.
These developments underscore the need to understand how labour mobility interacts with macroeconomic fluctuations and economic policies.
The quantitative model developed for this study captures key features of European labour markets, including unemployment, job creation, and workers' ability to search for employment either at home or abroad.
Migration decisions are endogenously determined by expected wages, employment prospects, and associated costs, allowing labour flows to respond dynamically to economic conditions in both interconnected regions.
This framework helps to address the gap in modern macroeconomic models regarding the integration of labour mobility.
Beyond a simple adjustment valve
This research provides a crucial framework for understanding the complex role of temporary migration, moving beyond simplistic views of it as a mere economic buffer.
The finding that migration significantly alters policy effectiveness and shock distribution means policymakers must integrate labour mobility into their stabilization strategies.
Ignoring these dynamics risks unintended cross-country spillovers and suboptimal policy outcomes in integrated areas like the EU.
