This paper shows that accounting for variation in mistakes can be crucial for welfare analysis. Focusing on consumer underreaction to not-fully-salient sales taxes, we show theoretically that the efficiency costs of taxation are amplified by differences in underreaction across individuals and...

The welfare contributions of the digital economy, characterized by the proliferation of new and free goods, are not well-measured in our current national accounts. We derive explicit terms for the welfare contributions of these goods and introduce a new metric, GDP-B which quantifies their...

The market access and welfare effects of Free Trade Areas (FTAs) without Rules of Origin (ROOs) are studied. We consider both the final and intermediate goods markets and their interlinkage. The FTA weakly reduces all tariffs and prices within the FTA. This raises quantity demanded and reduces...

The arrival of global retail chains in developing countries is causing a radical transformation in the way that households source their consumption. This paper draws on a new collection of Mexican microdata to estimate the effect of foreign supermarket entry on household welfare. The richness of...

Consumers often benefit from increased competition in differentiated product settings. In this paper we consider consumer benefits from increased competition in a differentiated product setting: the spread of non-traditional retail outlets. In this paper we estimate consumer benefits from...

This paper examines the impact of e-commerce on pricing behavior and welfare. Using Japanese data, we find that the entry of e-commerce firms significantly raised the rate of intercity price convergence for goods sold intensively online, but not for other goods. E-commerce also lowered relative...

We study intertemporal price discrimination when consumers can store for future consumption needs. To make the problem tractable we offer a simple model of demand dynamics, which we estimate using market level data. Optimal pricing involves temporary price reductions that enable sellers to...

In this paper I quantify a gain that a country receives when its global influence is considered to be admirable by others. I use a standard gravity model of bilateral exports, a panel of data from 2006 through 2013, and an annual survey conducted for the BBC by GlobeScan which asks people in up...

Satisfactory calculations of the welfare cost of aggregate consumption uncertainty require a framework that replicates major features of asset prices and returns, such as the high equity premium and low risk-free rate. A Lucas-tree model with rare but large disasters is such a framework. In a...

We propose new methods to model behavior and conduct welfare analysis in complex environments where some choices are unlikely to reveal preferences. We develop a mixture-of-experts model that incorporates heterogeneity in consumers' preferences and in their choice processes. We also develop a...
