上海自贸区跨境服务贸易负面清单制定的法律问题

上海自贸区跨境服务贸易负面清单的制定是落实《全面深化中国(上海)自由贸易试验区改革开放方案》,顺应国际服务贸易规则重构的重要举措之一。国民待遇的例外、市场准入的例外以及当地存在的要求是跨境服务贸易负面清单的涵盖范围;市场准入的例外不仅包括形式上的管理措施,还包括效果上的管理措施;当地存在与商业存在既有联系又有区别;跨境货物贸易与跨境服务贸易之间的界限值得厘清;兜底条款可纳入清单但适用应当谨慎。     

To Be or Not to be Temp? An Analysis of the Moderating Role of Motives for Accepting Temporary Employment

We investigate the role of contract volition and motives for accepting temporary employment in the relationship between precariousness of life and negative psychological symptoms in a sample of 275 Italian temps. Results suggest that the negative effect of contract volition on negative psychological symptoms is partially mediated by precariousness of life. A moderated mediation model shows that specific motives moderate the negative effects of contract volition on precariousness of life, so that when contract volition is higher, workers with weaker motives feel less precarious. This study broadens our understanding of temporary employment outcomes by showing that the negative consequences of precariousness of life seem to be less troublesome among temporary workers with higher contract volition and lower motivation. © 2018 ASAC.

The effect of activity identity fusion on negative consumer behavior

Negative consumer behavior is an important research topic as it explores consumer behaviors that threaten a brand's image and financial stability. However, prior research offers conflicting findings on whether a strong consumer‐brand relationship hurts or protects a brand after a market disruption or a brand transgression. To provide clarity on this issue, this work argues that disrupting the consumer‐activity relationship motivates consumers to reaffirm and protect their identity, thereby leading to negative consumer behavior. The data reveal that, after a brand‐initiated market disruption, consumers with high activity identity fusion are more likely to spread negative word‐of‐mouth, boycott the brand, and avoid repurchasing the brand in the future. Moreover, the data suggest that high brand identity fusion protects the brand during market disruptions; therefore, prior conflicting results may be due to the fact that the consumer‐activity relationship was not accounted for. Theoretically, this work establishes that consumers' relationship with their consumption activities has significant impacts on consumer behavior. Brand managers and marketers are urged to develop strategies that focus on strengthening the consumer‐brand relationship and not the consumer‐activity relationship.     

Welfare Cost of Fluctuations When Labor Market Search Interacts with Financial Frictions

We study the welfare costs of business cycles in a search and matching model with financial frictions. The model replicates the volatility on labor and financial markets. Business cycle costs are sizable. Indeed, the interactions between labor market and financial frictions magnify the impact of shocks via (i) a credit multiplier effect and (ii) an endogenous wage rigidity inherent to financial frictions. In addition, in a nonlinear framework, large welfare costs of fluctuations are explained by the high average unemployment and the low job finding rates with respect to their deterministic steady‐state values.     

矿产开发产生的负债与核算

鉴于负债的确认和核算是自然资源资产负债表编制的重点和难点,文章以国内外矿产资源资产负债的存在及其表现为线索进行分析与探讨,研究矿产资源开发产生负债运行机理和负债核算范围及内容等,揭示出矿产资源在其负外部性作用下形成负债的机理,并根据负外部性效应将矿产资源开发产生的负债划分为耗竭性负债、生态环境负债和安全负债,同时将耗竭性负债、生态环境负债和安全负债的核算范围与现有法律法规相衔接,提高负债核算的可操作性和可推广性,为自然资源资产负债表编制和维护国家所有者权益提供技术支撑。     

基于BP人工神经网络中国光伏产业贸易摩擦预警研究

建立有效的贸易摩擦预警系统有利于中国新兴产业的健康发展,有利于中国实施制造强国战略。将警兆信号法与人工神经网络相结合,从宏观经济形势、产业供给能力、双边贸易状况、市场需求水平等四个维度切入,构建了中国光伏产品出口贸易摩擦预警系统模型。预警分析表明,模型的预警效果与现实拟合较好,具有可行性。从模型的预警结果来看,2019年~2020年中国输美光伏产品贸易摩擦警情均低于轻警级别,仍面临一定的贸易摩擦风险。     

Collaboration and innovation: An empirical study of Indian technological enterprises

In 2010, the Indian government declared 2010–2020 to be the ‘Decade of Innovation’ and established the State Innovation Councils and Sectoral Innovation Councils to encourage and facilitate innovation by technological firms. In this paper, we study the relationship between collaboration and innovation in a cross‐section of Indian firms, paying particular attention to the impact of the innovation councils. Our results suggest that domestic collaborations have an important impact on firm innovation, as do the innovation councils, but that the impact of the councils is less for firms that collaborate.     

双边市场、不完全信息与二级价格歧视

本文研究了双边市场二级价格歧视问题。本文构建了包括广告商、消费者、垄断平台在内的两阶段博弈模型，研究了在最优与次优情况下平台的定价机制，分析了二级价格歧视对平台利润、社会福利等的影响。研究表明：（1）“顶部无扭曲”或“底部无扭曲”并不严格成立；（2）平台对观众提供的节目质量、广告插播量均可能出现类型逆转的情况；（3）二级价格歧视会增加社会总福利；（4）“会员制”是平台可能的占优定价机制之一。     

Money,Asset Prices,and the Liquidity Premium

This paper examines the effect of monetary policy on the market value of the liquidity services that financial assets provide, known as the liquidity premium. The theory predicts that money supply and nominal interest rates have positive effects on the liquidity premium, but asset supply has a negative effect. The empirical analysis with U.S. data confirms the theoretical predictions. The theory also proposes that the liquidity properties of assets can cause negative nominal yields when the money holding cost is low and liquid assets are scarce. The suggestive empirical findings in Switzerland to support this theoretical result are presented.
