The Aggregate Impact Of Consumer Reviews On Market Outcome In Differentiated Products Market, Jun B. Kim
The Aggregate Impact Of Consumer Reviews On Market Outcome In Differentiated Products Market, Jun B. Kim
Asia Marketing Journal
We investigate the aggregate impact of consumer reviews on market outcome in a differentiated product category. We model consumers as Bayesian learners who use online consumer reviews to learn and update their beliefs on product quality before their choice. For our empirical analysis, we use aggregate-level, longitudinal data from Amazon.com in the digital camcorder category and estimate the demand parameters. Using model estimates, we conduct two simulation studies and quantify the impact of consumer reviews on the market outcome. We report that the products experience heterogenous market share changes: the standard deviation of market share changes across products and time …
The Effect Of Consideration Set On Market Structure, Jun B. Kim
The Effect Of Consideration Set On Market Structure, Jun B. Kim
Asia Marketing Journal
We estimate a choice-based aggregate demand model accounting for consumers" consideration sets, and study its implications on market structure. In contrast to past research, we model and estimate consumer demand using aggregate-level consumer browsing data in addition to aggregatelevel choice data. The use of consumer browsing data allows us to study consumer demand in a realistic setting in which consumers choose from a subset of products. We calibrate the proposed model on both data sets, avoid biases in parameter estimates, and compute the price elasticity measures. As an empirical application, we estimate consumer demand in the camcorder category and study …
Effect Of Social Norm On Consumer Demand: Multiple Constraint Approach, Sungjee Choi, Inwoo Nam, Jaehwan Kim
Effect Of Social Norm On Consumer Demand: Multiple Constraint Approach, Sungjee Choi, Inwoo Nam, Jaehwan Kim
Asia Marketing Journal
The goal of the study is to understand the role of social norm in purchase decisions where demand is revealed in the form of multiple-discreteness. Consumers are socially engaged in various activities through the expectation from others in their community. Actions or decisions are likely to reflect this influence. This implicit or explicit social norm is revealed as the rules, regulations, and standards that are understood, shared, endorsed, and expected by group members. When consumers’ decisions are in distance from the norm, they come to face discomfort such as shame, guilt, embarrassment, and anxiety. These pressure act as a constraint …
Competitive Analysis Among Multi-Product Firms, Jun B. Kim
Competitive Analysis Among Multi-Product Firms, Jun B. Kim
Asia Marketing Journal
We analyze and study competition in differentiated product market using public data source. Understanding competitive market structure is critical for firms to assess how their products compete against other firms in a given market. In this paper, we estimate consumer demand, extend clout and vulnerability framework, and study competition among multi-product manufacturers in differentiated product market. For our empirical analysis, we adopt choice-based aggregate demand model and estimate consumer demand while accounting for unobserved product characteristics. Once we estimate consumer demand, we compute full price elasticity matrix and investigate intra- and inter- manufacturer substitutions among consumers. This research offers a …
