عوامل موثر بر ریسک قیمت محصولات در صنعت رستوران: تجزیه و تحلیل چرخه قیمت محصولات

The objectives of the present study were to (1) investigate the level and the extent of commodity price risk exposure in the restaurant industry and (2) identify the determinants of risk exposure. The risk exposure was estimated by 60-month rolling regressions based on equity returns. The determinants of equity risk exposure were proposed based on a discounted cash flow model. The results found that 35.39% of sample restaurant firms are exposed to commodity price risk. The level of equity risk exposure was estimated to be 1.148 during commodity price booms and 1.031 during slumps. Empirical testing was consistent with the model prediction that operating leverage and financial leverage are effective tools in managing risk exposure, but the effects are asymmetric during commodity price booms and slumps. Financial leverage was found to be more effective than operating leverage.
