Artificial intelligence (AI) has been used to develop and advance numerous fields and industries, including finance, healthcare, education, transportation and more. However, in the business negotiation field, such as bargain, the AI has not yet exerted its power. In order to explore the application of AI into business negotiation, we have built an intelligent robot that can help customers?that lack negotiation skills when bargaining in their shopping sceneries. This bot can make decision by itself via price prediction function implemented?by machine learning algorithms and the tool of decision tree. As a result, our bot has?got a positive performance during a used car trade. Although the algorithm of the project is relatively simple, its main contribution is to show the potential application of AI in the business negotiation. We believe that it can provide ideas and directions for the future development of business negotiation robot. 展开更多

The purpose of this study is to estimate the monetary value of the main environmental and external costs of Yali Hydropower Plant (YHPP) and to incorporate them into the financial viability indices of the plant, namely its net present value and electricity price. The results were found that if the electricity price is kept at its original level of 5.2 US cents/kWh to cover direct costs only, the net present value of the plant would be reduced to about 27% by incorporating environmental and external costs. Alternatively, the electricity price would have to be increased to 5.68 US cents/kWh in order to cover the full costs of YHPP and to maintain the original net present value. The main policy recommendations are: Government regulations should require that the financial analysis and appraisal of all future electricity sources include the full cost of these schemes, including not only direct costs but also environmental and external costs related to preventing or mitigating the environmental impact caused by them. An appropriate financial mechanism should be established to allocate the revenue from full cost electricity pricing to a fund to cover the environmental protection and compensation costs. 展开更多

We analyze whether product market advertising has a spillover effect on stock price synchronicity by transmitting firm-specific information to the capital market and attracting more investor attention.Using a sample of Chinese listed firms from 2009 to 2017,we find that firms with greater advertising expenditures have lower stock price synchronicity.The results are robust after we address endogeneity concerns.In accord with our hypothesis that product market advertising increases the amount of firm-level information capitalized into stock prices through the information channel,we find that the impact of advertising on synchronicity is more pronounced for firms with a higher degree of information asymmetry and firms in the consumer-product industry.Further tests show that product market advertising enhances the ability of current period returns to reflect future earnings,and thus rules out that the negative relationship between advertising and synchronicity is driven by noise trading.Our results imply that product market advertising plays an informative role and improves information efficiency in a capital market. 展开更多

The spread of the COVID-19 will have a negative impact on international prices in a short time.This article compares the four oil price slumps in the past half century with the slump caused by the COVID-19,and concludes that the current drop in oil prices is not very serious.It is expected that international oil prices will recover rapidly with the end of the outbreak.The average international oil price in 2020 will be slightly lower than that in 2019.If Japan,South Korea,Iran and Italy can take effective measures to curb the outbreak as soon as possible,international oil prices will remain within the analysis range in the fall of quantity and price on the demand side.The annual average Brent price should be slightly reduced based on an analysis of Chinese factors.However,if it continues to spread around the world and becomes out of control in the Islamic oil and gas producing countries,it is likely that the oil price will increase due to insufficient supply. 展开更多
