We measure how the bundling of television channels affects welfare. We estimate an industry model of viewership, demand, pricing, bundling, and input market bargaining using data on ratings, purchases, prices, bundles, and input costs. We conduct simulations of à la carte policies that require...

We start from an aggregate random coefficients nested logit (RCNL) model to provide a systematic comparison between the tractable logit and nested logit (NL) models with the computationally more complex random coefficients logit (RC) model. We first use simulated data to assess possible...

We model a trader’s decision to supply liquidity by submitting limit orders or demand liquidity by submitting market orders in a limit order market. The best quotes and the execution probabilities and picking off risks of limit orders determine the price of immediacy. The price of immediacy...

In this paper I develop the Discrete Choice Analytically Flexible (DCAF) model of demand for differentiated products. DCAF relaxes the constraints imposed on the matrix of own- and cross-price elasticities of demand by popular analytic discrete choice models such as the Multinomial Logit (MNL)...

We present a method for identifying and estimating the gains from trade in limit order markets and provide new empirical evidence that the limit order market is a good market design. The gains from trade in our model arise because traders have different valuations for the stock. We use...

This paper discusses the existence of 'home' biases in the 19th century global capital market, whereby colonies appear to have received a 'disproportionate' amount of capital from their metropolis. Starting from a discussion of the Bulow Rogoff (1989) problem, we argue that imperial links...

We use hedonic prices and purchase quantities to consider what can be learned about household willingness to pay for baskets of organic products and how this varies across households. We use rich scanner data on food purchases by a large number of households to compute household specific lower...

What determines the sustainability of sovereign debt? In this paper, we develop a model where myopic governments seek electoral popularity but can nevertheless commit credibly to service external debt. They do not default when they are poor because they would lose access to debt markets and be...
