The effects of banning loss-leader pricing in grocery retailing markets
with Jorge Florez-Acosta
This paper explores the effects of banning loss-leader pricing in grocery retailing markets. To this end, we carry out two empirical exercises. First, we obtain reduced-form evidence on the effect of banning loss-leader pricing on price levels using data on purchases of a number of products widely used by supermarkets as loss-leaders. As half of the states in the US ban loss-leading practices, we exploit a border strategy estimation along with expected changes in demand to identify the effect of banning loss-leading on average prices. Second, we structurally model competition between supermarkets to capture the effects of the ban on optimal pricing. Our empirical strategy relies on a novel approach for demand estimation that allows us to work with a reduced set of products, while still correcting for the biases generated by such restricted choice set.
Valuing non-marginal changes in mortality and morbidity risk - [Accepted for publication at Journal of Health Economics]
with James K. Hammitt and Christoph Rheinberger
Many stated-preference studies that estimate the willingness-to-pay (WTP) for reductions in mortality or morbidity risk suffer from inadequate scope sensitivity. One possible reason is that the risk reductions typically presented to respondents are too small to be meaningful. Survey responses may thus not accurately reflect respondents' preferences for health and safety. In this paper we propose a novel way of estimating the value per statistical life (VSL) or the value per statistical case (VSC) based on risk reductions measurable as percentages. While such non-marginal risk reductions are easier to understand, they introduce well known feedback effects. We develop a methodology to de-bias VSL and VSC estimates derived from the evaluation of non-marginal risk reductions and prove the concept using simulated data.
