Evaluating the Effects of Cash-Based Interventions on the Integration of Vulnerable Venezuelan Migrants in Peru: Key Findings Using a Multidimensional Approach to Measure Migrant Integration Outcomes.

With Monica Aguilar Folch, Ace Dela Cruz, Jobst Koehler, Morgane Reina and Karla Sulca (IOM) and Dominik Hangartner, Marine Casalis, Rodrigo Sanchez (ETH Zurich).


This study report analyzes the effect of the multi-purpose cash-based intervention (CBI) program implemented by the International Organization for Migration (IOM) in Peru on migrants’ psychological, economic, political, social, linguistic, and navigational integration, as well as in other outcome variables. The multi-purpose CBI provided was a one-off payment of 760 soles (approximately USD 200) to highly vulnerable Venezuelans refugees and migrants living in Peru with the main objective of covering immediate basic needs.

The main takeaway of the causal impact evaluation, conducted by the Immigration Policy Lab (IPL) at ETH Zurich and IOM, is that the cash transfer receipt had a positive and statistically significant effect on the level of integration three months after the beneficiaries received the assistance. The IPL Integration Index - which serves as a core survey instrument of the Multidimensional Integration Measurement Toolkit - was used to measure integration and was specifically adapted to the Peruvian context as part of a cooperation between IOM and IPL. According to the results, the multi-purpose CBI leads to a statistically significant increase in the integration of Venezuelan refugees and migrants1. The positive effect on overall integration is driven by navigational, social, and economic dimensions, less so by the political or psychological dimensions.

The statistical analysis shows that multi-purpose CBI has only a small and marginally significant effect on the probability of employment of between 0.62 and 1.83 percentage points. However, the cash transfer significantly increases the probability of self-employment between 1.94 and 4.95 percentage points, suggesting that beneficiaries used some of the cash payment for establishing their own small-scale businesses. The effect of the cash transfer program on integration is larger for women, respondents above 31 years old, single-person households and for respondents in a regular migratory situation. Also, the effect is greater as the level of household income and level of education rise.

Impact evaluation of the job vacancy notice obligation I

With Rafael Lalive, Patrick Arni, Tobias Lehmann, Dominik Hangartner, Joëlle Pianzola, 2021.


This report presents the conclusions of a study on the effects of the job vacancy notice obligation (JVNO) on the labour market and immigration. The study covers the JVNO with an 8% unemployment level threshold from July 2018 to December 2019. The impact is measured using the statistical methods of difference-in-differences (DID) analysis and regression discontinuity design (RDD) on register data (specifically the AVAM employment and labour market statistics system, the ASAL unemployment insurance payment system and the ZEMIS central migration information system).

Trends in rental price inflation and the introduction of rent pressure zones in Ireland.

With Martinez-Cillero, M. and O’Toole, C., 2019. Economic and Social Research Institute.


Rental price inflation in the private residential sector in Ireland has accelerated rapidly in recent years. This is the consequence of a confluence of factors which have led to an undersupply of both rental and owner-occupier housing and growing demand due to demographic household formation and a recovering economy. In an attempt to limit the rate of rent inflation, price controls were enacted in December 2016, which limited the rate of increase in rents to 4 per cent per annum in areas designated as Rent Pressure Zones (RPZs). RPZs can be classified at the local authority (LA) or local electoral area (LEA). A number of exemptions are available for landlords.

This study aims to understand and document the trends in rental prices in Ireland before and after the introduction of RPZs. It compares the trends in areas classified as RPZs relative to selected comparison groups of unclassified LEAs to identify whether changes in the inflation rate are evident after the policies were introduced. A range of methods have been used to undertake this assessment, including analysing the trends and developments at an LEA level using the quarterly Rent Index official series as well as an analysis at the property level using a matched sample from the RTB database.
