混业经营制度下国有商业银行产品创新战略研究

对于国有商业银行来说,加入WTO后如何确定产品创新的战略目标和策略,发挥核心产品的优势为客户提供满足个性化需求的金融产品,从而赢得客户、扩大市场份额,是一项重大课题。本文从混业经营制度下的商业银行产品创新入手,分析了国内分业经营制度下,商业银行产品创新存在不能有效利用各要素市场,不能满足客户个性化需求,无法适应市场竞争的不足及其原因。在此基础上,作者提出了国有商业银行混业经营的目标路径和步骤;在混业经营制度下的产品创新战略定位选择;国有商业银行金融产品创新策略,包括机制创新、队伍创新、平台创新和产品创新。     

股权制衡、非国有股东委派董事与公司绩效

从公司治理层面完善国有控股企业的股权制衡是国企混合所有制改革的重点和难点,以往学者仅仅研究了股权制衡与公司绩效之间的关系,很少研究两者关系的作用路径和影响机理.因此,引入非国有股东委派董事这一概念,研究非国有股东委派董事在股权制衡与公司绩效之间发挥的中介效应.结果表明:股权制衡有利于公司绩效的提升,非国有股东委派董事在股权制衡与公司绩效两者之间发挥了中介效应.     

N‐FIRM OLIGOPOLY WITH GENERAL ISO‐ELASTIC DEMAND

In this note oligopoly with iso‐elastic demand is analysed. Unlike previous studies we consider general iso‐elastic demand rather than the case of unit elasticity. An n‐firm Nash‐Cournot equilibrium for the case of heterogeneous constant marginal costs is derived. The main result is a closed‐form solution that shows the dependency of the equilibrium on the elasticity of demand and the share of industry costs. The result has applications to a wide range of areas in oligopoly theory by allowing comparisons across markets with different elasticities of demand.     

发达国家住房福利政策的演变及启示——我国公租房领域供给侧结构性改革探析

我国公租房领域存在投资主体单一、政府财政压力大、市场参与度不够、配置低效、供需失衡及错配、贫富分区程度加大等问题，需通过推进供给侧结构性改革来予以解决。发达国家住房福利政策的演变表明，住房政策应与住房市场供需状况相适应，政府所扮演的角色须从“公共住房的直接供给者”走向“市场化供给的环境营造者”，即从“补砖头”到“补人头”是住房福利政策演进的必然趋势。我国公租房领域供给侧结构性改革应与住房供求情况相匹配。一方面，要转变政府职能，从政府实物配给逐步过渡到市场化供给；另一方面，要积极打造健康的住宅租赁投资市场以促进公租房供给市场化，并通过开发配建和货币化补贴等措施促成公租房“隐形化”混合居住模式。     

Corruption in agricultural processing firms: A comparison of cooperatives and investor-owned firms

This paper examines managerial corruption in cooperatives (co-ops) and investor-owned firms (IOFs), including its impact on prices and farmer welfare. Even when co-op managers have greater incentives to engage in corruption because of the co-op's larger production, the resulting corruption is not sufficient to offset the competitive effect that co-ops exert vis-à-vis IOFs. This conclusion holds regardless of the functional form of the production function, the farm input supply curve, and the demand curve for the processed product. In addition to showing the robustness of the competition effect, the paper provides a highly flexible modeling framework that can be used to examine other co-op behavior questions.     

Measuring the effectiveness of US monetary policy during the COVID-19 recession

The COVID-19 recession that started in March 2020 led to an unprecedented decline in economic activity across the globe. To fight this recession, policy makers in central banks engaged in expansionary monetary policy. This paper asks whether the measures adopted by the US Federal Reserve (Fed) have been effective in boosting real activity and calming financial markets. To measure these effects at high frequencies, we propose a novel mixed frequency vector autoregressive (MF-VAR) model. This model allows us to combine weekly and monthly information within a unified framework. Our model combines a set of macroeconomic aggregates such as industrial production, unemployment rates, and inflation with high-frequency information from financial markets such as stock prices, interest rate spreads, and weekly information on the Fed's balance sheet size. The latter set of high-frequency time series is used to dynamically interpolate the monthly time series to obtain weekly macroeconomic measures. We use this setup to simulate counterfactuals in absence of monetary stimulus. The results show that the monetary expansion caused higher output growth and stock market returns, more favorable long-term financing conditions and a depreciation of the US dollar compared with a no-policy benchmark scenario.     

The relationship between people's activities and values with the protection level and biodiversity

We investigated how people's recreational activities, values, and land use preferences are related to the protection level, biodiversity and cultural heritage values of nature-based tourism areas in northern Finland. We assessed peoples' opinions using a public participation geographic information system (PPGIS) and analyzed the data together with spatial biodiversity and cultural heritage data from the same area. Associations between the PPGIS place markings with the protection level and biodiversity values were quite low, and for the cultural heritage sites they were altogether missing. Negative preferences were often marked in areas with high numbers of sites rated as pleasant and they overlapped with each other, indicating conflicting preferences. Since most activities are not noticeably related to the protection level or biodiversity values of a site they can be planned so as to protect the biodiversity of the area.     

舾装作业中考虑周期驱动的虚拟单元多阶段动态调度研究

多品种小批量离散型生产企业面临的大量不确定因素会干扰其生产的连续性,其中,船舶生产由于其技术与管理特点在此类生产中具有典型性.本文将以船舶舾装生产为例,在保证设备负荷均衡及资源利用率的基础上,研究该环节的虚拟单元调度问题,以提高企业的生产效率.文章以最小运输距离为目标,在充分考虑瓶颈资源约束的基础上,构建周期驱动下分割计划期的数学模型,并以结合任务分配和时间约束的混合蚁群算法求解.通过在某船厂舾装环节的应用发现,本文所提方法能够有效降低当前舾装各作业的平均完成时间,具备可行性.

On pure-strategy Nash equilibria in price–quantity games

This paper examines the existence and characteristics of pure-strategy Nash equilibria in oligopoly models in which firms simultaneously set prices and quantities. Existence of a pure-strategy equilibrium is proved for a class of price–quantity games. If the demand function is continuous, then the equilibrium outcome is similar to that of a price-only model. With discontinuous demand and limited spillover, there are rationing equilibria in which combined production falls short of market demand. Moreover, there might again be an equilibrium reflecting the outcome of a price game. Competition in price and quantity thus yields Bertrand outcomes under a variety of market conditions.
