讲座题目:Subsidies for Green Technology Adoption under Uncertain Demand and Incomplete Information

讲座摘要:In order to comply with strict emission controls, manufacturers in different industries are replacing traditional high-emission equipment with new ones powered by green technology. Alternative regulations, notably the equipment subsidy policy (ESP) and the operation subsidy policy (OSP), have been proposed to align manufacturers’ decisions with governments’ objectives. This study investigates manufacturers’ timing decisions to adopt green technology under ESP and OSP, respectively. In our study the market demand consists of a public stochastic component and a private certain component, which is observable only by the manufacturer and can be promoted by his costly effort. A principal-agent model is developed in which the regulation on the adoption timing is specified as a call option exercised by the government, and constrained by the manufacturer’s incentive compatibility (IC), participation constraint (PC), ex ante IC, and ex ante PC. Our results suggest that the optimal subsidy policies exhibit stepwise structures, which are dependent on the realization of demand under complete information, and dependent on both demand realization and the manufacturer’s effort cost under incomplete information. The optimal ESP and OSP are equivalent under complete information. Under incomplete information, these two policies lead to the same adoption timing if the demand is high, although the ESP may require a larger subsidy budget. Otherwise the ESP promotes earlier adoption than the OSP. These results largely hold if a potential competitor’s market entry is also considered. Our study is applied to a case study of a chemical shipping company’s vessel replacement decisions.
