Reaping the full benefits from cross-border interconnection typically requires reinforcement of national networks. When the relevant parts of the networks are complements, a lack of coordination between national transmission system operators typically results in investment below optimal levels in...

While existing work has demonstrated that campaign donations can buy access to benets such as favorable legislation and preferential contracting, we highlight another use of campaign contributions: buying reductions in regulatory enforcement. Specically, we argue that in return for campaign...

In view of training increasingly complex learning architectures, we establish a nonsmooth implicit function theorem with an operational calculus. Our result applies to most practical problems (i.e., definable problems) provided that a nonsmooth form of the classical invertibility condition is...

This paper investigates pooling strategies for tail index and extreme quantile estimation from heavy-tailed data. To fully exploit the information contained in several samples, we present general weighted pooled Hill estimators of the tail index and weighted pooled Weissman estimators of extreme...

Superspreading has been suggested to be a major driver of overall transmission in the case of SARS-CoV-2. It is therefore important to statistically investigate the tail features of superspreading events (SSEs) to better understand virus propagation and control. Our extreme value analysis of...

We study oligopolistic competition by firms practicing second-degree price discrimination. In line with the literature on demand estimation, our theory allows for comovements between consumers’ taste for quality and propensity to switch brands. If low-type consumers are sufficiently less (more) brand...

Online intermediaries greatly expand consumer information, but also raise sellers’ marginal costs by charging high commissions. To prevent disintermediation, some platforms adopted price parity and anti-steering provisions, which restrict sellers’ ability to use alternative sales channels. Whether...

Nonparametric inference on tail conditional quantiles and their least squares analogs, expectiles, remains limited to i.i.d. data. Expectiles are themselves quan- tiles of a transformation of the underlying distribution. We develop a fully operational kernel-based inferential theory for extreme...

Despite its sophistication, Early Modern Japan, 1600-1868, had among the lowest real wage levels ever recorded, half of those in pre-industrial England. This paper resolves this puzzle by considering the more equal landownership distribution in Japan relative to Europe. Due to institutional...

There is public and scholarly debate about the effects of personalized recommender systems implemented in online social networks, online markets, and search engines. Some have warned that personalization algorithms reduce the diversity of information diets which confirms users’ previously held...
