The US Census Bureau regularly releases Public Use Microdata Samples (PUMS), data files which contain de-identified subsets of the data provided by respondents to some of its various surveys and to the Decennial Census itself. This allows data users to perform “micro” -analyses rather than the “macro” -tabulations which are regularly performed by the Bureau. These data users range from non-gove...

News consumption is moving online. If this move fundamentally changes how news is produced and consumed it will have important ramifications for politics. In this chapter we formulate a model of the supply and demand of news online that is motivated by descriptive features of online news consumption. We estimate the demand model using a combination of microdata and aggregate moments from a pane...

K-anonymity is the most widely used approach to privacy preserving microdata which mainly based on generalization. Although generalization-based k-anonymity approaches can achieve protection objective, they suffer from information loss. Clustering-based have been successfully adapted for k-anonymization as enhance data quality, however, computational complexity of finding an optimal solution ha...

This paper develops multiple-prior Bayesian inference for a set-identi…ed parameter whose identi…ed set is constructed by an intersection of two identi…ed sets. We formulate an econometrician’s practice of "adding an assumption" as "updating ambiguous beliefs." Among several ways to update ambiguous beliefs proposed in the literature, we consider the DempsterShafer updating rule (Dempster (1968...

Welfare, Labor Supply and Heterogeneous Preferences: Evidence for Europe and the US Following the report of the Stiglitz Commission, measuring and comparing well-being across countries has gained renewed interest. Yet, analyses that go beyond income and incorporate non-market dimensions of welfare most often rely on the assumption of identical preferences to avoid the difficulties related to in...

Widespread and persistent political underrepresentation of immigrant-origin minorities poses deep challenges to democratic practice and norms. What accounts for this underrepresentation? Two types of competing explanations are prevalent in the literature: accounts that base minority underrepresentation on individual-level resources and accounts that emphasize political opportunity structures. H...

Using 1990 Census microdata, we explore ethnic, racial, and immigrant differences in private school attendance. We find high rates of private school attendance among white natives, white immigrants, and Asian natives. In contrast, we find low private school rates among black and Hispanic natives and immigrants. Asian immigrants, and other natives. Variations in income per capita and especially ...

This essay is a contribution to the empirical literature on the effect of inflation tax on capital structure. A simple empirical model considering the main results of the current theoretical development is studied, using microdata from a number of American corporations.

Data release has privacy disclosure risk if not taking any protection policy. Although attributes that clearly identify individuals, such as Name, Identity Number, are generally removed or decrypted, attackers can still link these databases with other released database on attributes (Quasi-identifiers) to re-identify individual’s private information. K-anonymity is a significant method for priv...

In the data privacy context, specifically, in statistical disclosure control techniques, microaggregation is a well-known microdata protection method, ensuring the confidentiality of each individual. In this paper, we propose a new approach of microaggregation to deal with semantic sets of categorical data, like text documents. This method relies on the WordNet framework that provides complete ...
