基金业绩归因与投资者行为

本文以2006年1月至2016年12月中国64家股票型主动管理基金为样本,从基金净资金流变化的角度,检验了投资者决策与基金业绩结构的关系,以期更好地理解投资者行为。本文结论有:(1)整体上,投资者在衡量基金经理能力时,更关注原始超额收益率或只基于市场风险调整风险敞口,这可能与中国市场投资工具仍然不够充分、风险难以有效对冲有关;(2)机构投资者相比个人投资者对风险敞口的识别更严格;(3)简单模型的优势集中在市场波动低、投资者情绪高的时期;(4)除基金经理能力外,净资金流变化对市场风险报酬也很敏感;(5)从alpha的角度,我国基金市场仍存在“赎回异象”,可能与“处置效应”有关,仍需提升投资者对风险的认知,引导市场形成更加科学的投资观念。     

放松卖空约束、现金持有水平及其市场价值——基于公司治理角度研究

基于放松卖空约束的政策实施,运用双重差分法考量放松卖空约束对现金持有行为影响及其产生的经济后果。结果显示：放松卖空约束增加了公司现金持有量,同时也增加了公司现金持有的边际市场价值;按照公司内部代理成本分组来看,内部代理成本越大的公司,放松卖空约束的治理效果越明显;进一步检验中,通过一系列稳健性检验发现主要结论依然成立;机制性检验表明放松卖空约束通过抑制公司过度投资行为增加了现金持有及其市场价值。结果表明：放松卖空约束作为一项重要的金融创新工具,可以通过外部治理监督作用缓解公司内部代理问题,从而影响上市公司现金持有行为。     

疫情如何影响企业发展预期?——基于压力传导机制的实证研究

公共卫生事件对企业微观经济行为的影响尚未引起足够的关注。立足于中国当前的疫情背景和制度环境,本文利用最新的“企业开工力”问卷调查数据,考察了新冠肺炎疫情对企业发展预期的影响和机制。研究发现,疫情降低了企业在未来开展经济行为的意愿;机制分析表明,紧张的现金流是疫情降低企业行动意愿的重要途径,具体表现为疫情分别通过提高来自现金流、违约金、还付贷款和员工工资等方面的资金支付压力,进而降低企业的发展预期。进一步分析表明,企业在疫情爆发前的活跃程度越高、所在市级地区的营商环境越好,疫情对企业发展预期的负向影响会越强;而且,疫情与企业发展预期间的关系在不同程度上受到企业所在地区疫情状况以及企业产权性质、所属产业类别等异质性因素的影响。在使用一系列稳健性检验后,上述结论依然稳健。本研究将企业经济行为的影响因素拓展至公共卫生安全领域,不仅揭示了公共卫生事件影响企业经济行为的微观机理,而且还为疫情防控下政府出台扶持企业相关政策提供了决策参考。     

Improving the efficiency targeting of Malawi's farm input subsidy programme: Big pain,small gain?

The Farm Input Subsidy Programme (FISP) in Malawi was introduced in the 2005/2006 season against a background of bad weather affecting production and prolonged food shortages. Vouchers are distributed empowering eligible farmers to exchange them for fixed quantities of inputs at subsidized prices. Since its inception, there has been a debate at national level about whether the FISP’s potential has been fully exploited, with policy makers exploring options to improve the programme. Proposals include targeting efficient and productive farmers to maximize returns. In this paper, we evaluate the effectiveness of these proposed changes to the existing FISP design by utilizing two waves of the LSMS-ISA survey merged with climatic data. We estimate how the national demand for agricultural inputs varies according to a variation in the targeting criteria by means of a two-stage demand system. Then, we identify more efficient farmers by means of a stochastic frontier approach. We observe a mismatch between voucher recipients and efficiency, with approximately 60% of vouchers being allocated to the three bottom quintiles of efficiency. This mismatch is observed also at the spatial level with more vouchers going to districts characterized by less efficient production. While concerns on the distributional impacts of the new criteria are discussed together with some suggestions for spatially diversifying the structuring of the policy and incentivizing crop diversification, our results highlight a high substitutability of commercial with subsidized inputs by new eligible farmers. Consequently, simulating the targeting policy variation we obtain an outcome that would lead only to a limited increases in predicted food expenditure ranging from 0.27% to 0.8% and maize production from 0.2% to 1.3. Scope for analysing different adjustments in the functioning of FISP are, thus, proposed to policy makers.     

The impact of ultimate controller’s ownership on cash dividend policy based on a comparative analysis between owner-management and professional-management modes

This study uses Chinese listed firms to examine the relation between the ultimate controller’s ownership and cash dividends under different allocation modes of management rights. The empirical results show that under the professional-management mode, the ultimate controller’s ownership and dividend payments form an inverted U-shaped relation which results from the ultimate controller’s monitoring and collusion with the executive. Under the owner-management mode, the ultimate controller’s ownership and dividend payment levels assume a U-shaped relation which is attributed to its interest encroachment and convergence effect. The shape flip from professional-management to owner-management is the result of the changing opportunity cost of the controller’s dividend payments.     

Land use changes to cash crop plantations: crop types,multilevel determinants and policy implications

Cash crop plantation has recently become an expanding global phenomenon. Characterizing the dynamics of cash crop plantations and the corresponding determinants should provide critical references for land use policy. Using aerial photos and geographic information system, this paper investigated the trends of four types of cash crops (tea, fruit, mulberry and nursery) and their relations to other land use changes within Hangzhou region in subtropical China. Results showed that the total cash crop cultivated surface increased by 541.3 ha from 2004 to 2014. Most of the new tea and fruit plantations were established in places previously used as forest and woodland. Mulberry and nursery mainly expanded by replacing paddy, woodland and forest. By combining household survey, geospatial techniques and multilevel regression, multilevel determinants of cash cropping probability and cash crop expansion were quantified. At the parcel level, tea and fruit plantations inclined to occur on hilly land with gentle slope. Mulberry and nursery plantations were likely to be observed in flat areas with low elevation. Parcels covered by high quality soils and with convenient communications experienced greater cash cropping probability. At the household level, households constituted of female and old-aged labor or with low agricultural labor intensity demonstrated high probability of tea and mulberry plantations. Conversely, households constituted of middle-aged labor or with high agricultural labor intensity tended to grow more fruit and nursery. Besides, wealthier households were prone to establish fruit and nursery plantations but were reluctant to involve in tea and mulberry cropping. At the village level, population density was a significant determinant of cash cropping probability, but was an insignificant determinant of cash crop expansion. Greater occurrence of cash cropping was observed in villages with higher proportion of migrant labor and leasing land. Distance to county road and distance to provincial road were identified as negative determinants. Policy was evidenced to be of significant influence on cash cropping probability and cash crop expansion. We argue that a balance should be achieved between cash cropping promotion and natural resources protection in formulating the local land use policy.     

'Classical' Roots of Input-Output Analysis: A Short Account of its Long Prehistory

This paper discusses the roots of input-output analysis in 'classical' economics. The authors considered include Petty and Cantillon; Quesnay, the physiocrats and their critic Isnard; Smith, Ricardo, Torrens and Dmitriev; Marx, von Bortkiewicz and von Charasoff; Leontief; and Remak. It is argued that, in terms of method and content, input-output analysis is akin to the classical approach to the theory of production, distribution and relative prices in that (i) it requires all magnitudes to be observable and (ii) starts essentially from the same set of data. It is shown that many important modern concepts have been anticipated by the earlier authors. The prehistory of input-output analysis is also meant to provide new perspectives on potential future developments of the field.     

Scheduling a maintenance activity and due-window assignment based on common flow allowance

We study a due-window assignment problem on a single machine. The job-dependent due-windows are obtained by the common flow allowance criterion. The scheduler has the option to perform a maintenance activity which is rate modifying, i.e., improves the processing times of the following jobs. We consider a number of versions of this setting: (i) The maintenance requires a constant time, (ii) The maintenance duration is an increasing function of its starting time (linear deterioration), and (iii) The maintenance duration is position-dependent (general deterioration). We study the standard setting of regular job processing times, and investigate also the extension to position-dependent processing times. The set of potential optimal positions for the maintenance activity is fully characterized. Consequently, the problems based on all the combinations of these settings are shown to be solved in polynomial time.
