This paper shows how to build algorithms that use graphics processing units (GPUs) installed in most modern computers to solve dynamic equilibrium models in economics. In particular, we rely on the compute unified device architecture (CUDA) of NVIDIA GPUs. We illustrate the power of the approach...

We evaluate whether hospital adoption of electronic medical records (EMRs) leads to increases in billing where financial gains are large or where hassle costs of complete coding are low. The 2007 Medicare payment reform varied both financial incentives and hassle costs of coding. We find no...

I reflect on the role of modern economic history in economics. I document a substantial increase in the percentage of papers devoted to economic history in the top-5 economic journals over the last few decades. I discuss how the study of the past has contributed to economics by providing ground...

Expanding insurance coverage could, by insulating patients from having to pay full cost, encourage the utilization of arguably unnecessary medical services. It could also eliminate (or at least diminish) the need for emergency services through increasing access to preventive care. Using publicly...

The No Child Left Behind (NLCB) Act required states to adopt accountability systems measuring student proficiency on state administered exams. Based on student test score performance in 2002, states developed initial proficiency rate targets and future annual benchmarks designed to lead students...

We examine the relationship between the adoption of EMR and hospital operating costs. We first identify a puzzle that has been seen in prior studies: Adoption of EMR is associated with a slight cost increase. We draw on the literature on IT and productivity to demonstrate that the average effect...
