| This study estimates Canadian consumers' willingness to pay for food safety improvements and identifies systematic misassessments of food-borne risks. Non-hypothetical experimental auctions were used to elicit consumer valuations of food safety improvement. Consistent with behavioural research, results suggest that subjects generally overestimate the likelihood of becoming ill due to food-borne disease relative to scientifically-estimated odds. Subjects were willing to pay a positive amount to reduce food-safety risk. Risk reductions' valuations increased with higher initial risk, supporting arguments of diminishing marginal value for risk reductions. |

| Modern theories of sales make conflicting predictions about the temporal pattern of sales, which we test using grocery scanner data. We examine both frozen orange juice, which consumers can store, and refrigerated orange juice, which is more perishable, to determine what role—if any—durability plays in the pattern of sales. We start with a simple reduced-form probit analysis to examine the timing of sales and whether sales are determined nationally by manufacturers or locally by retailers. We then turn to a vector autoregressive analysis and conduct Granger tests of temporal ordering (“causality tests”) to determine whether the sale of one brand is followed in a predictable way by the sale of another brand or its own later sales. Based on the VAR... |

| The 1990 Clean Air Act Amendments stipulated gasoline content requirements for metropolitan areas with air pollution levels above predetermined federal thresholds. The legislation led to exogenous changes in the type of gasoline required for sale across U.S. metropolitan areas. This paper uses a panel of detailed wholesale gasoline price data to estimate the effect of gasoline content regulation on wholesale prices and price volatility. In addition, we investigate the extent to which the estimated price effects are driven by changes in the number of suppliers versus geographic segmentation resulting from regulation. We find that prices in regulated metropolitan areas increase significantly, relative to a control group, by an average of 3.6 cents per... |
