讲座题目:Should Tech Companies Offer More Alternatives for Innovative Products?


Technology companies frequently face the problem of how many alternatives to offer consumers for their innovative products. Unlike traditional products, the quality of innovative products is usually unfamiliar to consumers (we refer to the unknown element as opaque quality), which makes results in previous studies on product variety unsuitable. In this paper, we build a simple stylized model to answer this product breadth problem. Consumers, who are behaviorally inattentive, evaluate both the design and quality of the product and make purchase decisions, and the technology company decides how great the product variety should be. Our analytical model is accompanied by experimental evidence.

The contribution of our paper is threefold. First, the model fills a vacuum in the literature on product variety decisions by considering both horizontal and vertical differentiation, as well as behavioral inattention. We show a tradeoff between product fit and perceived quality, which serves as a novel incentive for firms to limit product variety. Second, the experiment helps with understanding how consumers choose innovative products from a consumer behavioral viewpoint. Third, we also provide practical guidelines and important implications for marketing managers. Notably, we show that when the opaque quality of a product is large, the company should offer a limited number of alternatives.

讲座题目:Effect of EPR coefficient policy on the production decision in precious metal accessory recycling


This study examines the effect of the Extended Producer Responsibility (EPR) coefficient policy on the production decision between a supplier and a manufacturer in a precious metal accessory recycling supply chain. EPR coefficient is a regulation proposed by the government and enterprises to balance economic profit and EPR behavior, and refers to the production proportion of recycled products in all serviceable products. Enterprises with a large EPR coefficient have good EPR practice. This study uses the newsvendor model and numerical simulation to study a supply chain system with remanufacturing and reproduction processes. Results show that the optimal recycling mode and the optimal EPR coefficient are always present in precious metal accessory operations. The increasing market demand for recycled products and the improving whole recycling parameters are both effective in enlarging the optimal EPR coefficient. However, the improvement of single or partial recycling parameters (except the market demand parameter) has no effect on the optimal EPR coefficient. The implementation mechanism and applicable conditions of the EPR coefficient policy are also explored. This study indicates that the EPR coefficient policy is an appropriate and effective approach to promote the EPR practice of the Chinese Government.
