Generate a conceptual model based on the following information. In marketing, brand differential (i.e., the differences between a private brand and a national brand) has been demonstrated to influence consumers' general purchase behaviors. Specifically, many empirical studies support that brand differential (i.e., BD) directly influences consumers' purchase intentions (i.e., PI). In addition, brand differential indirectly influences consumers' purchase intentions through consumers' motivation to conform to social norms (i.e., MCSN). In your answer, (a) specify the constructs (6%), (b) specify the directions (6%), and (c) provide a diagram (4%)
