英文文献摘要：
Interest in the influence of trust on consumers’ responses to food risk perceptions associated with Canadian instances of BSE motivates this study, in which Canadian households’ expenditures on fresh meat are assessed in the context of the first three recurring risk events in which bovine spongiform encephalopathy (BSE) was found to have affected Canadian cows. Engel Curve analysis focusing on the dynamics of the monthly meat expenditure shares for a selected sample of 437 Canadian households for 2002 through 2005 is applied based on data on household expenditures for meat purchased by a national sample of Canadian households from the Nielsen Homescan? Canadian panel, supplemented by survey responses on BSE risk perceptions and measures of trust. Two sets of models are estimated: Engel curves in differences with instruments in levels and Engel curves in levels with instruments in differences. It is found that habit persistence limited households’ reductions of beef purchases following the first BSE event and that that trust limited households’ reduction in beef expenditure shares following the subsequent two BSE cases. Significant seasonal effects and a significant negative influence on beef expenditure shares are also found, consistent with the trend of declining consumption of beef in Canada since the late 1990s.
