Taste Heterogeneity, IIA, and the Similarity Critique

By: Thomas J. Steenburgh and Andrew Ainslie

The purpose of this paper is to show that allowing for taste heterogeneity does not address the similarity critique of discrete-choice models. Although IIA may technically be broken in aggregate, the mixed logit model allows neither a given individual nor the... View Details

Charitable Giving When Altruism and Similarity Are Linked

By: Julio J. Rotemberg

This paper presents a model in which anonymous charitable donations are rationalized by two human tendencies drawn from the psychology literature. The first is people's disproportionate disposition to help those they agree with while the second is the dependence of... View Details

Quality Provision, Expected Firm Altruism and Brand Extensions

By: Julio J. Rotemberg

This paper studies quality choice in a model where consumers expect firms to act altruistically. It is shown that, under plausible assumptions regarding this altruism and the reaction of consumers to firms that demonstrate insufficient altruism, existing firms (or... View Details

Do Inventory and Gross Margin Data Improve Sales Forecasts for U.S. Public Retailers?

By: Saravanan Kesavan, Vishal Gaur and Ananth Raman

Firm-level sales forecasts for retailers can be improved if we incorporate cost of goods sold, inventory, and gross margin (defined here as the ratio of sales to cost of goods sold) as three endogenous variables. We construct a simultaneous equations model, estimated... View Details

When Does the Market Matter? Stock Prices and the Investment of Equity Dependent Firms

By: Malcolm Baker, Jeremy Stein and Jeffrey Wurgler

We use a simple model of corporate investment to determine when investment will be sensitive to non-fundamental movements in stock prices. The key cross-sectional prediction of the model is that stock prices will have a stronger impact on the investment of firms that... View Details

Nominal versus Indexed Debt: A Quantitative Horse Race

By: Laura Alfaro and Fabio Kanczuk

The main arguments in favor of and against nominal and indexed debt are the incentive to default through inflation versus hedging against unforeseen shocks. We model and calibrate these arguments to assess their quantitative importance. We use a dynamic equilibrium... View Details

Bayesian Estimation & Black-Litterman

By: Joshua D. Coval and Erik Stafford

Describes a practical method for asset allocation that is more robust to estimation errors than the traditional implementation of mean-variance optimization with sample means and covariances. The Bayesian inspired Black-Litterman model is described after introducing... View Details

Second-Sourcing and the Experience Curve: Price Competition in Defense Procurement

By: James J. Anton and Dennis A. Yao

We examine a dynamic model of price competition in defense procurement that incorporates the experience curve, asymmetric cost information, and the availability of a higher cost alternative system. We model acquisition as a two-stage process in which initial production... View Details

Identifying Sources of Inefficiency in Health Care

By: Amitabh Chandra and Douglas O. Staiger

In medicine, the reasons for variation in treatment rates across hospitals serving similar patients are not well understood. Some interpret this variation as unwarranted and push standardization of care as a way of reducing allocative inefficiency. However, an... View Details

Altruistic Dynamic Pricing with Customer Regret
