In this paper, we consider the network as an alternative trading environment to the market. The main distinctive feature of the network transaction is the dependence of buyers' purchasing behavior, which makes all consumers not equally valuable to a seller. We characterize the optimal behavior...

This paper investigates how conditional quantiles of a given distribution relate to each other. Given two conditional quantiles estimated nonparametrically, we investigate their relation by linking them through a parametric transformation. Asymptotic normality of the associated parameter vector...

This paper analyzes conditions under which various k-class estimators are asymptotically normal in a simultaneous equations framework with many weak instruments. In particular, our paper extends the many instruments asymptotic normality results obtained by Morimune (1983), Bekker (1994), Angrist...

In this paper, I develop a quasi empirical likelihood estimator that has good finite-sample properties when there are many moment conditions. I show that the quasi empirical likelihood estimator, which uses semiparametric efficient estimation, is an approximation to the empirical likelihood...

This paper considers the possibility that a seller can contract with one uninformed buyer prior to an auction involving two potential buyers. In a more general setting than previous literature, strategic ex-ante contracts not only extract rent from entrants, but could also mitigate the...

One result of the deregulation of utilities in New Zealand has been the bypass of existing networks. We investigate two cases of bypass in the distribution of natural gas, and compare the welfare properties of regulation vs.\ the `laissez-faire' equilibrium. We demonstrate that installing a...
