This book presents statistical methods for the analysis of events. The primary focus is on single equation cross section models. The book addresses both the methodology and the practice of the subject and it provides both a synthesis of a diverse body of literature that hitherto was available largely in pieces, as well as a contribution to the progress of the methodology, establishing several new results and introducing new models. Starting from the standard Poisson regression model as a benchmark, the causes, symptoms and consequences of misspecification are worked out. Both parametric and semi-parametric alternatives are discussed. While semi-parametric models allow for robust interference, parametric models can identify features of the underlying data generation process

Ever since New Zealand became a British colony in 1840, it has attracted considerable numbers of European migrants. In the 1996 Population Census, 80 percent of the 3.6 million New Zealand residents claim European ethnic descent. While European immigration always has been, and continues to be, dominated by the UK, some noticeable Dutch immigration took place since 1950. Beginning in the 1960s, the overall share of European migration started a downward trend, with more and more immigrants arriving from the Pacific Islands and Asia.

The paper provides an analysis of the recent immigration history of New Zealand and Australia. It starts with a description of the quantitative dimension of immigration: how many immigrants entered the two countries, and what was the contribution of external migration to population growth. Next, similarities and differences in the current immigration policies are studied. Finally, an attempt is made to evaluate policy outcomes using empirical evidence of immigrants arriving in the 1990s.
