This paper analyses the remittance behaviour of two cohorts of migrants who entered Australia before and after a policy change implemented in the 1990s, which tightened the entry requirements for a subgroup of applicants. We use a mix of a conditional difference-in-differences and OLS estimator...

This paper analyses the impact of a change in Australia's immigration policy, introduced in the mid-1990s, on migrants' remittance behaviour. More precisely, we compare the remittance behaviour of two cohorts who entered Australia before and after the policy change, which consists of stricter...

Technological change and globalization have sparked debates on the changing demand for skills in western labour markets, especially for middle skilled workers who have seen their tasks replaced. This paper provides a new data set, which is based on text data from curricula of the entire Dutch...

This paper assesses the relationship between courses taken in high school and college major choice. Using High School and Beyond survey data, I study the empirical relationship between college performance and different types of courses taken during high school. I find that students sort into...

In social interaction models, the identification of the network effect is based on either group size variation, structure of the network or the relative position in the network measured by the Bonacich centrality measure. These identification strategies imply the use of many instruments or...

The problem of weak instruments is due to a very small concentration parameter. To boost the concentration parameter, we propose to increase the number of instruments to a large number or even up to a continuum. However, in finite samples, the inclusion of an excessive number of moments may be...

The use of many moment conditions improves the asymptotic efficiency of the instrumental variables estimators. However, in finite samples, the inclusion of an excessive number of moments increases the bias. To solve this problem, we propose regularized versions of the limited information maximum...
