We study asset and debt characteristics of US bank holding companies. We show that financial institutions, especially large institutions, are not just about holding discrete assets. Services and going-concern values are important, and capital market debt against going-concern values accounts for...

Audits are a common mechanism used by governments to monitor public spending. In this paper, we discuss the effectiveness of auditing with theory and empirics. In our model, the value of audits depends on both the underlying presence of abuse and the government's ability to observe it and...

We model early expectations about the value and technological importance ('quality') of a patented innovation as a latent variable common to a set of four indicators: the number of patent claims, forward citations, backward citations and family size. The model is estimated for four technology...

We present a model of lending markets with imperfect competition, adverse selection and costly lender screening. In more competitive markets, lenders have...

This paper examines the economic foundations of some recently proposed criteria for evaluating the benefits of social programs. These criteria are appropriate for comparing a class of revenue-constant policies. They replace foundational principles of social opportunity costs with accounting...

We study the effect of photo ID laws on voting using a difference-in-differences estimation approach around Rhode Island's implementation of a photo ID law. We employ anonymized administrative data to measure the law's impact by comparing voting behavior among those with drivers' licenses versus...
