We provide a framework with multiple worker types (e.g. gender, age, education) to decompose changes in aggregated and disaggregated measures of between-group inequality into changes in (i) the composition of the workforce across labor types, (ii) the importance of different tasks, (iii) the extent...

We study the asymptotic inference for a conditional moment equality model using highfrequency data sampled within a fixed time span. The model involves the latent spot variance of an asset as a covariate. We propose a two-step semiparametric inference procedure by first nonparametrically recovering...

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-...
