We propose an approach to modeling and estimating discrete choice demand that allows for a large number of zero sale observations, rich unobserved heterogeneity, and endogenous prices. We do so by modeling small market sizes through Poisson arrivals. Each of these arriving consumers then solves...

The population of the United States, as with the rest of the world, is aging rapidly, with the most rapid growth occurring among the age 85 and older population, those who rely most on long-term care. In this chapter, we review the delivery and financing of long-term care in the U.S. We show...

The developed world is in the midst of an enormous demographic transition, with life expectancy increasing and fertility falling, leading to a rapid aging of the population. This trend has critical implications for long-term care around the world. This paper serves as the introduction to a...

The population is aging in Denmark, as in many other countries, due to increasing life expectancy and a low total fertility rate. This potentially puts the Danish welfare state under pressure. This paper discusses the demographic and socioeconomic situation of the elderly in Denmark, focusing on...

The U.S. population is aging. We examine whether immigration causally affects the likelihood that the U.S.-born elderly live in institutional settings. Using a shift-share instrument to identify exogenous variation in immigration, we find that a 10 percentage point increase in the less-educated...

Societal aging is arguably one of our most critical demographic challenges, and Singapore is aging at a much faster rate compared to other countries. Population aging could negatively affect older adults, contribute to an increase in healthcare expenditure and increase caregivers' financial and...

We study how organizational boundaries affect pricing decisions using comprehensive data from a large U.S. airline. We document that the firm's advanced pricing algorithm, utilizing inputs from different organizational teams, is subject to multiple biases. To quantify the impacts of these...

Airfares fluctuate due to demand shocks and intertemporal variation in willingness to pay. I estimate a model of dynamic airline pricing accounting for both sources of price adjustments using novel flight-level data. I use the model estimates to evaluate the welfare effects of dynamic airline...

Manufacturers of durable goods can encourage consumers facing transaction costs to upgrade by accepting used units as trade-ins. These "buyback schemes" increase demand for new units, but increase the supply of used units if trade-ins are resold. In this paper, I investigate the equilibrium...

We introduce a model of oligopoly dynamic pricing where firms with limited capacity face a sales deadline. We establish conditions under which the equilibrium is unique and converges to a system of differential equations. Using unique and comprehensive pricing and bookings data for competing...
