新中国成立70年农村基本经营制度的历史演进与发展取向——基于农村土地制度和农业经营制度的改革联动视角

研究目的:剖析农村土地制度和农业经营制度的关系,为完善农村基本经营制度提供参考。研究方法:比较分析法、文献研究法。研究结果:新中国成立70年来,农村基本经营制度先后历经新中国成立初期的"农民所有、家庭经营"、改革开放前期的"集体所有、集体经营"到改革开放后期的"集体所有、均田承包、家庭经营",再到现阶段的"集体所有、均田承包和多元经营"4个阶段。在这个过程当中,农村基本经营制度既遵循人口与土地关系、生存与发展关系以及政府与市场关系的大逻辑,又遵循着农村土地制度的"产权逻辑"、农业经营制度的"生产逻辑"等小逻辑。研究结论:为深化农村基本经营制度变革,需加强农村土地制度与农业经营制度联动改革的制度设计,发挥要素、组织和制度的作用,发展多种形式的适度规模经营,实现小农户与现代农业发展的有机衔接。     

Distribution of residual autocorrelations for multiplicative seasonal ARMA models with uncorrelated but nonindependent error terms

In this paper, we consider portmanteau tests for testing the adequacy of multiplicative seasonal autoregressive moving‐average models under the assumption that the errors are uncorrelated but not necessarily independent. We relax the standard independence assumption on the error terms in order to extend the range of applications of the seasonal autoregressive moving‐average models. We study the asymptotic distributions of residual and normalized residual empirical autocovariances and autocorrelations under weak assumptions on noise. We establish the asymptotic behavior of the proposed statistics. A set of Monte Carlo experiments and an application to monthly mean total sunspot number are presented.     

The complexity of consumer experience formulation in the sharing economy

The study examines the complexity of the factors that influence overall perception among tourists who use peer-to-peer accommodation during their vacations. More specifically, it employs fuzzy-set Qualitative Comparative Analysis to analyse data from a sample of 712 peer-to-peer holidaymakers visiting Athens, Greece, and examines the socio-demographics of age and income along with the simple attributes of perceived risks, marketing and advertising, social aspects, and price and quality issues. The findings reveal three sufficient configurations that are able to influence the overall experience: (i) the price-quality nexus, (ii) risk perspective, and (iii) social interaction. The research also compares nonlinear analysis with the dominant parametric methods in tourism and hospitality research (regression; Cramer’s V), highlighting the suitability of the former for complexity examination. It further progresses from fit to predictive validity for the examined models, and contributes to both theoretical and methodological domains.     

The role of the Securities and Exchange Commission in a developing economy: Implications for IFRS

Due to the widespread adoption of IFRSs throughout the world and little research on IFRS implementation in developing countries, this study investigates the role of the Securities & Exchange Commission (SEC) regarding IFRS implementation in a developing country. Adopting a mixed methodology (39 interviews and 1647 enforcement documents); the findings have raised concerns as to the adequacy of enforcement mechanisms in implementing IFRSs in Bangladesh. More specifically, only 2.6% of enforcement actions were issued over the period of 1998 to 2010. Political connectedness is the major contributing factor for uneven enforcement activities in Bangladesh. The study also finds that inconsistencies with accounting regulatory framework (Companies Act, BSEC ordinances and IFRSs), multiple regulators, and donor agencies' influence impede the effective implementation of IFRSs. The study also provides policy implications for local and national policy makers namely, IASB, the World Bank and the IMF to rethink about the regulation of IFRSs in developing countries.

Sources of business fluctuations: Financial or technology shocks?

Despite the widespread belief that technology shocks are the main source of business fluctuations, recent empirical studies indicate that in the absence of financial frictions, a shock to the marginal efficiency of investment is the main source and is closely related to financial conditions for investment. We incorporate a financial accelerator mechanism and two types of financial shocks to the external finance premium and net worth in a dynamic stochastic general equilibrium model with shocks to the marginal efficiency of investment, the investment-good price markup, and the rates of neutral and investment-specific technological changes. This model is estimated using eleven US time series that include data on loan, net worth, the loan rate, and the relative price of investment. Our estimation results show that the (non-stationary) neutral and investment-specific technology shocks primarily drive output and investment fluctuations, while the external finance premium shock plays an important role for investment fluctuations. This financial shock induced substantial falls and subsequent sharp hikes in the external finance premium and caused boom–bust cycles over the past two decades.     

创始股东保护问题研究——国美股权与控制权之争对中国公司治理的启示

国美虽在英属维尔京群岛注册，在香港交易及结算所有限公司上市，但仍不失为一家典型的中国式家族企业。国关事件展示了一个失衡的公司治理架构，即管理层可在两权分离的立法模式下实现内部人控制，风险投资人可通过议定投资协议来约束管理层，但创始股东则因受制于一股一权的强制性规范而容易失去对公司的控制权。为维护其创业诉求，建议创始股东除传统控股，还应特别设计公司章程来预留特定董事席位，并约定优先股等保护条款。     

How important is fiscal policy cooperation in a currency union?

By constructing a dynamic stochastic general equilibrium model, which assumes a currency union consisting of two countries with nontradables, we study the importance of fiscal policy cooperation. As shown in the previous studies, we find that the role of fiscal policy is important in maximizing social welfare. However, we have a contrary result for fiscal policy cooperation. While the previous studies highlight that fiscal policy cooperation has a nontrivial effect in maximizing social welfare, we show that fiscal policy cooperation has no benefits, regardless of the share of nontradables. Self-oriented fiscal policy can replicate social welfare under the cooperative setting.     

俄罗斯科技型初创企业:值得关注的中俄科技合作伙伴

在实施以创新为核心的国家发展战略的背景下,俄罗斯涌现出一批致力于前沿科技研发及高科技产品的科技型初创企业。这些科技型初创企业发展的主要原因在于俄罗斯政府的作用:出台法律法规,鼓励科研单位和高校创办企业;搭建平台,推动重点领域科技研发;拓展资助渠道,为创新项目提供定制化金融服务;实施专项计划,重点支持应用研究的发展;启动知识产权私有化,推动智力成果的实际应用;等等。该类企业大多具有2个突出特点:在创始人或项目参与者中,年轻人比重较大;主要从事信息通讯、生物医药、节能和能源、航天技术等战略性技术领域的研发。通过研究俄罗斯科技型初创企业的发展原因及突出特点,对中俄在高技术和创新领域的合作提出了具体建议。
