Shape constrained nonparametric estimation dates back in the 1950's. In his milestone paper in 1956, Grenander found the maximum likelihood (ML) estimator of a nonincreasing density, whereas Brunk (1958) obtained the least squares estimator of a monotone regression function. After the derivation of...

We propose a model of posted prices in networks. The model maps traditional concepts of market power, competition and double marginalization into networks, allowing for the study of pricing in complex structures of intermediation such as supply chains, transportation networks and decentralized...

An agent sequentially collects information to obtain a principal’s approval, such as a pharmaceutical company seeking FDA approval to introduce a new drug. To capture such environments, we study strategic versions of the optimal stopping time problem first proposed by Wald (1945). Our flexible...

We use overdispersed Poisson regression models to study social networks in finance. We count an investor's social connections in different cities as proportional to the number of stocks held by this investor that are headquartered in those cities. When connections are formed in an i.i.d. manner,...

This paper analyses the extent of inter-format retail competition between supermarkets, discounters and drugstores in Germany, using data from the German market for diapers. We estimate a random coefficient logit model at the individual household level. Based on consumer substitution patterns, we...

In this paper we derive a new handy integral equation for the free-boundary of infinite time horizon, continuous time, stochastic, irreversible investment problems with uncertainty modeled as a one-dimensional, regular diffusion X. The new integral equation allows to explicitly find the free-...

Why do governments borrow both domestically and abroad? What determines the composition of domestic and external borrowing? How does that composition in turn affect the probability of a sovereign default? We address these and other related questions within an extension of the dynamic general...

Circular labor migration is a core feature of low-income labor markets. Yet, evidence on how this migration affects education investments in sending communities is limited due to lack of high quality data and challenging identification issues. This is especially true in Africa, where children can...
