Tidskriftsartikel (refereegranskat)abstract
- China's employment issue is catching people's eyes at present and for a long time. Economic impacts of China's petroleum industry on employment are divided into direct, indirect and induced impacts and they are analysed in this study by using the input-output approach. The research results suggest that petroleum industry will supply 0.0957 jobs and 0.1501 jobs given 10,000 CNY final demand added in extraction of petroleum and processing of petroleum respectively; 1,887 CNY and 2,756 CNY of employment income will be affected given 10,000 CNY final demand added in extraction of petroleum and processing of petroleum respectively; extraction of petroleum has more direct impact on both employment number and employment income given one unit output added, and processing of petroleum has more indirect and induced impact on them. The petroleum industry's impact coefficients on both employment number and employment income have been decreasing since 1987. The proportion of direct impacts in total impacts continues to decrease, and the connection between petroleum industry and other sectors in China's national economy has become closer than before.

Refund polices for core collecting regarding the customers’ responses
- 2014

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- To encourage the return of cores, remanufacturers in practice commonly charge a certain amount of purchasing deposit, and refund it to the customer based on the result of quality inspection in the return process. Two types of classification errors exist and interact with each other during such an inspection process: either low quality cores are defined as remanufacturable; or high quality cores are defined non-remanufacturable. A remanufacturer has to choose a combination them and determine a proper deposit value, with the consideration of customers’ possible responses concerning purchasing and return behaviors. Within a game theory framework, the analytical solutions of these issues are firstly developed under the assumption that the customer has the inspection error information. When this information is not available, the solutions are analyzed with a given and fixed deposit. The value of information transparency in inspection errors is shown by comparing these two settings. The salvage value of different cores also has a great influence on the remanufacturer’s profit. In addition, the effect of conservatively estimating customers’ product payoff and the influences of improving inspection accuracy are investigated numerically. Interestingly, the customer may return more low quality cores when the inspection accuracy is improved.
