Forecasting bilateral asylum seeker flows with high-dimensional data and machine learning techniques
We develop monthly asylum seeker flow forecasting models for 157 origin countries to the EU27, using machine learning and high-dimensional data, including digital trace data from Google Trends. Comparing different models and forecasting horizons and validating out-of-sample, we find that an ensemble forecast combining Random Forest and Extreme Gradient Boosting algorithms outperforms the random walk over horizons between 3 and 12 months. For larg…
Immigration, labor markets and discrimination
Venezuela is currently experiencing the biggest crisis in its recent history. This has led more than 7.3 million Venezuelans to emigrate, at least 1.5 million of those to Peru, which amounted to an increase of over 4 percent in the Peruvian population. Venezuelan immigrants in Peru are relatively similar in cultural terms, but, on average, more skilled than Peruvians. In this paper, we first examine Venezuelans’ perceptions of being discriminated…
Immigration, Labor Markets and Discrimination
Venezuela is currently experiencing the biggest crisis in its recent history. This has led to a large increase in emigration. According to recent estimates, there are a total of 5.6 million Venezuelan immigrants worldwide with over one million now living in Peru, which has led to an over 2 percent increase in the country’s population. Unlike in many other episodes of refugee migration, Venezuelan immigrants are not only very similar in cultural t…
