The discipline of operations management is rarely studied with an eye on public policies. Yet, it is glaring to even the casual observer that public infrastructure is very different in different countries. How does public infrastructure affect private sector inventory levels? I develop as a...

We ask if corporate executives have fixed effects (quirks) that explain perational decisions made in firms, independent of firm effects. We replicate the approach in Bertrand et al. (2003), solving the empirical challenge of distinguishing firm and executive effects by constructing a dataset of...

How different are retailers' inventory levels around the world? Specifically, are retailers' inventories constant across countries, converging, or at least co-integrating? These might be viewed as various forms of global determinism. To see which of these forms hold, I use a novel dataset...

We posit a theory that runs counter to how conventional wisdom thinks about analyst bias, that it is the result of distorted incentives by "the system" - especially upstream factors like the analysts' employers. We suggest that analysts are also heavily influenced by what investors believe, the...
