For the past few decades, scholars in statistical and social sciences have acknowledged that heterogeneity is prevalent subjects of their studies. The literature on individualized treatments...
This article analyzes rural-urban migration in Great Britain in the latter half of the nineteenth century. Using a new dataset of 28,000 individuals matched between the 1851 and 1881 population censuses, I examine the selection process and treatment effect of migration, controlling for the endogeneity of the migration decision. I find that urban migrants were positively selected—the best of the...
This paper assesses the methodology employed in longitudinal studies of advertising and youth drinking and smoking behaviors. These studies often are given a causal interpretation in the psychology and public health literatures. Four issues are examined from the perspective of econometrics. First, specification and validation of empirical models. Second, empirical issues associated with measure...
The Australian hospital system is characterized by the co-existence of private hospitals, where individuals pay for services and public hospitals, where services are free to all but delivered after a waiting time. The decision to purchase insurance for private hospital treatment depends on the trade-off between the price of treatment, waiting time, and the insurance premium. Clearly, the potent...
In this paper, we look at conventional methods for removing endogeneity bias in regression models, including the linear model and the probit model. The usual Heckman two-step procedure should not be used in the probit model: from a theoretical perspective, this procedure is unsatisfactory, and likelihood methods are superior. However, serious numerical problems occur when standard software pack...
Immigrants, Ethnic Identities and the Nation-State In the Western world, multiculturalism has become the way to view and form “nationhood,” igniting the interest to understand and model identity. The complexity of identity formation, however, has been firm and ethnic and national identities have been deviating more and more. In this paper, we seek to investigate the nature, role and relationshi...
We use data from eBay to identify hundreds of thousands of instances in which retailers posted otherwise identical product listings with targeted variation in pricing and auction design. We use these matched listings to measure the dispersion in auction prices for identical goods sold by the same seller, to estimate nonparametric auction demand curves, to analyze the effect of buy it now option...
This paper explores how changes in marital status affected men's wealth accumulation in mid-nineteenth-century America, using a longitudinal sample of Union Army veterans linked to the 1860 and 1870 census manuscript schedules. Controlling for the endogeneity of wealth and marital selection, this paper provides strong evidence that marriage had positive effects on men's wealth accumulation, whe...
Using longitudinal data from the Canadian National Population Health Survey (NPHS), we study the relationship between health and employment among older Canadians. We focus on two issues: (1) the possible problems with self-reported health, including endogeneity and measurement error, and (2) the relative importance of health changes and long-term health in the decision to work. We contrast esti...
