Bertrand versus Cournot competition in a downstream mixed oligopoly with foreign ownership

Focusing on foreign ownership in the private firm, we examine the Cournot-Bertrand comparison in a mixed oligopolistic market with vertical market structure. We have found that if public and private firms were charged with uniform price for their inputs, then Cournot-Bertrand ranking in market outcomes confirms those obtained by Ghosh and Mitra (2010). This implies that under uniform pricing in the upstream sector, the vertical market structure does not have substantial influences on Cournot-Bertrand ranking. However, if discriminatory pricing is adopted, firm's profits, output, and social welfare are often reversed to those obtained from uniform pricing in the upstream sector. Given the closeness of products, if the share of foreign ownership is sufficiently low, social welfare in Cournot competition can exceed that of Bertrand competition, contrasting with the standard welfare ranking that Bertrand welfare is strictly higher than Cournot. This implies that Cournot competition can be more socially desirable than Bertrand in mixed oligopoly with vertical market structure if discriminatory pricing scheme is adopted by foreign upstream monopolists.     

林权流转价格及其影响因素分析

以林农拥有的活立木为研究对象,利用2007—2017年浙江省1546宗活立木流转样本,采用多元线性回归实证分析了是否在林权交易中心交易对活立木流转价格存在影响。结果表明:关键解释变量是否在林权交易中心进行交易对活立木流转价格具有显著的正向影响;流转面积、单位面积蓄积、区域虚拟变量、坡度等对流转价格都产生一定程度的影响;流转期限对流转价格的影响不大。因此,需要加强对林权交易中心的宣传,降低相关的交易成本,从而吸引更多的小规模林农参与交易。     

Superreplication with proportional transaction cost under model uncertainty

We consider a discrete‐time financial market with proportional transaction cost under model uncertainty, and study a superreplication problem. We recover the duality results that are well known in the classical dominated context. Our key argument consists in using a randomization technique together with the minimax theorem to convert the initial problem to a frictionless problem on an enlarged space. This allows us to appeal to the techniques and results of Bouchard and Nutz to obtain the duality result.     

The Impact of Farmland Transfers on Agricultural Investment in China: A Perspective of Transaction Cost Economics

There is growing concern that farmland transfers lead to less agricultural investment, which may adversely affect agricultural productivity growth in China. Prior research has primarily focused on the differences between owned cultivated land and rented plots, but little is known about how farmland transfers between relatives, which are popular in rural China, specifically affect agricultural investment. In this paper, we present a conceptual framework of transaction cost economics to compare different contracting strategies in China's farmland rental markets. As farmland rental markets in China are immature, land transfer between relatives establishes bilateral governance, which has the advantage of addressing the opportunistic activities of both parties and can ultimately increase investment by tenants. Based on data from two waves of household surveys, we empirically examine the impact of bilateral governance on the application of organic fertilizer, an indicator for agricultural investment. Our findings show that apart from economic factors, kinship is important to the functioning of farmland rental markets in rural areas.     

Increasing Shopper Trust in Retailer Technological Interfaces via Auditory Confirmation

This research examines the effects of sounds made by retail technological interfaces – self-checkout kiosks, credit card readers, mobile apps, websites – at point-of-sale. We propose that such sounds, retail transaction auditory confirmation (RTAC), increase trust in technological interfaces by providing auditory confirmation that stages of the checkout process have been successfully executed. Increased trust in technological interfaces leads to positive downstream consequences in the form of satisfaction and purchase intention. Visual and auditory distraction in the retail environment reduces trust, even when visual confirmation is provided, but synchronously provided audio-visual confirmation attenuates the negative effects of environment distraction.     

确权、交易、资产化：对大数据转为生产要素基础理论问题的再思考

大数据是数字经济的基础性、战略性资源，是后疫情时代经济发展的重要生产要素，但社会各界对大数据的理论认知仍落后于其应用实践，而且大数据确权、交易定价、资产化问题也存在诸多争议，这对大数据产业和数字经济的持续健康发展形成潜在隐患，也成为制约大数据向生产要素正常转化并参与社会大生产的关键。文章在对大数据概念、属性重新认识的基础上，综合财经、法律等理论观点和实操技巧，阐述了大数据如何从商品流通要素演变为社会生产要素的市场逻辑以及使用价值如何注入大数据的资产化过程，并从实践视角提出大数据确权的法理基础和大数据交易所生态下交易定价模型。同时提出以数据税来弥补大数据采集环节个人和企业放弃的小微权利，将私权转化为社会公共产品，为大数据产业和要素市场发展提供新的借鉴。     

Environmental taxes,reforms and economic growth: an empirical analysis of panel data

This paper explores the relationship between environmentally related taxes and the economic growth rate. The analysis also investigates whether this relationship differs between countries that have implemented environmental tax reforms (ETRs) and those that have not. Using panel data from 31 OECD countries over the period 1994–2013, the paper finds that when we allow environmentally related tax revenues to interact with an initial level of real GDP per capita, the overall revenues of these taxes are negatively associated with the economic growth rate in the short and long term. Furthermore, we show that the higher the initial level of GDP per capita, the more environmentally related tax revenues can promote the economic growth rate. The analysis also reveals that the relationship between environmentally related tax revenues and economic growth varies between countries that have a mechanism to redistribute environmentally related tax revenues and those that do not.     

论国际投资仲裁中第三方资助披露问题

国际投资仲裁中的第三方资助不同于国际商事仲裁中的第三方资助,应对其进行专门研究。披露是规制第三方资助的关键。国际投资仲裁中关于第三方资助披露的规则呈现出缺位和模糊的总体特点。在国际投资仲裁中,第三方资助的受资助方基本均为申请人。由相关案件可知,现行实践与规则并不适配。实践中,披露的发起一般经由被申请人请求或仲裁庭要求,被申请人要求披露的原因常见于利益冲突和透明度,仲裁庭对披露要求的拒绝一般基于对披露程度的考量。将规则与实践对比分析可知,规定仲裁庭要求披露的时间,严格把控第三方资助的披露程度,是完善国际投资仲裁中第三方资助披露规制的可行路径。
