This paper provides an analysis of the role of prices in determining food purchases and nutrition using very detailed transaction-level observations for a large, nationally-representative sample of US consumers over the period 2002-2007. Using product- specific nutritional information, we...

We use Nielsen Homescan data to examine who bears the economic burden of cigarette taxes. We find cigarette taxes are less than fully passed through to consumer prices, suggesting consumers and producers split the excess burden of these taxes. Using information on consumer location, we show the...

Current methods of estimating the random coefficients logit model employ simulations of the distribution of the taste parameters through pseudo-random sequences. These methods suffer from difficulties in estimating correlations between parameters and computational limitations such as the curse...

orldwide, postal and delivery economics has attracted considerable interest. Numerous questions have arisen, including the role of regulation, funding the Universal Service Obligation, postal reform in Europe, Asia and North America, the future of national postal operators, demand and pricing...

The trend towards Internet self-regulation is driven both by governments that feel reluctant to invest in direct regulation (because of freedom of speech concerns or high costs of monitoring and enforcement) and by the industry that is under the threat of rising public concerns over content...

This paper shows that in finite samples it is not possible to distinguish all the latent factors from the idiosyncratic noise and that this leads to a bias towards the identification of a single factor. It provides an approximation to this bias and the corresponding sampling distribution.

<p><p>In this paper we introduce a new flexible mixed model for multinomial discrete choice where the key individual- and alternative-specific parameters of interest are allowed to follow an assumption-free nonparametric density specification while other alternative-specific coefficients are assumed...</p></p>

This paper proposes a quantile regression estimator for a model with interactive effects potentially correlated with covariates. We provide conditions under which the estimator is asymptotically Gaussian and we investigate the finite sample performance of the method. An approach to testing the...
