This paper examines the optimal sequencing of sales in the presence of network externalities. A firm sells a good to a group of consumers whose payoff from buying is increasing in total quantity sold. The firm selects the order to serve consumers so as to maximize expected sales. It can serve all...

This paper provides evidence of local innovation spillovers, i.e. innovation by one firm fostering innovation by neighboring firms. First, I document that exogenous shocks to innovation by listed firms affect innovation by private firms in the same geographical area. I also find that such local...

This paper considers inference on treatment effects using repeated cross sections. Contrary to the standard setting of difference-in-differences, we suppose that perfect control and treatment groups cannot be defined. Units may be treated in the "control group", while some units may remain...

Covariance matrix estimation and principal component analysis (PCA) are two cornerstones of multivariate analysis. Classic textbook solutions perform poorly when the dimension of the data is of a magnitude similar to the sample size, or even larger. In such settings, there is a common remedy for...

We consider the problem of testing for uniformity on high-dimensional unit spheres. We are primarily interested on non-null issues. To this end, we consider rotationally symmetric alternatives and identify alternatives that are contiguous to the null of uniformity. This reveals a Locally and...

Horizontally differentiated asset exchanges split the order flow from liquidity traders. These traders have heterogeneous preferences over exchange characteris- tics and experience a positive liquidity externality from trading in the same place. We show that the co-existence of suitably...
