The Financing of Research and Development

Evidence on the ‘funding gap’ for R&D is surveyed.The focus is on financial-market reasons for under-investmentin R&D that persist even in the absence of externality inducedunder-investment. The conclusions are that (i) small and newinnovative firms experience high costs of capital that are onlypartly mitigated by the presence of venture capital; (ii) evidencefor high costs of R&D capital for large firms is mixed,although these firms do prefer internal funds for financingthese investments; (iii) there are limits to venture capitalas a solution to the funding gap, especially in countries wherepublic equity markets are not highly developed; and (iv) furtherstudy of governmental seed capital and subsidy programmes usingquasi-experimental methods is warranted.

郎溪剖面石英粒度和沉积物粒度特征对比与意义分析

在郎溪剖面全样中提取石英矿物，与原始沉积物在各粒度特征上有着显著异同。粒度组成上粉砂＞黏粒＞砂砾，而沉积物粒度黏粒含量更高且在下蜀黄土层出现不一致的分布规律；石英中值粒径偏大而二者众数粒径范围相似；石英平均粒径偏大，分选系数较好，偏度多为近对称态而沉积物粒度多为负偏态；石英峰态更加尖锐。通过引入粒度频率曲线、累积频率曲线以及粒度端元分解法对二者粒度特征做出解析，指出：石英作为稳定矿物较易保存原始沉积环境的粒度信息；红土形成时期曾遭受强风化作用导致沉积物黏粒增多；加积型红土形成环境可能与下蜀黄土存在一定差异；二者粒度参数分布虽呈现不一致的特征，但总体上都具有相同的指示性；黏粒可能由自然成壤改造作用形成；细粉砂可能是冬季风远距离搬运的沙漠黄土物质；粗粉砂可能是冬季风近距离搬运的河漫滩物质；砂砾可能是夏季风近距离搬运的粗粒跃移组分。对郎溪剖面形成时期沉积动力与沉积环境做出判断，对于印证石英与沉积物在各粒度特征上的应用性，以及恢复气候旋回背景下的古环境变化具有独特的研究意义。     

Indonesian universities in transition: catching up and opening up

Indonesia's higher education system is changing rapidly: in 2010 there were about 5 million students, up from 2,000 in 1945. Effectively the tertiary system has four tiers, three of which are within the public sector. However, the system is increasingly private sector driven. The key themes of this paper on universities are rapid growth; overcoming the historical backlog; and the need for further fundamental reform. The quality of Indonesia's tertiary institutions is highly variable. Governance structures and incentives regimes within the state universities are complex and obscure. The government both over-regulates and under-regulates. Major reforms are under way and increasing financial resources are available.     

Self-selection and performance of R&D input of heterogeneous firms: Evidence from China's manufacturing industries

Applying the theories of heterogeneous firms and the propensity score matching difference-in-differences (PSM-DID) method to a rich dataset of Chinese manufacturing firms, this paper examines the self-selection of firm-level R&D input and estimates the net effect of R&D on productivity. The analysis shows that (1) for Chinese manufacturing firms as a whole, R&D input is influenced by firm productivity: more productive firms are more likely to invest in R&D; (2) controlling for the self-selection effect, the net output elasticities of R&D input in one year and two years after R&D input are 3.92% and 5.25%, respectively; (3) although state-owned enterprises (SOEs) are more likely than all other ownership groups to invest in R&D, the R&D input is not productive; (4) although enterprises owned by investors outside of Mainland China are the least likely to invest in R&D, the output elasticity of R&D is more significant and larger in this group than in SOEs and privately owned Chinese firms; and (5) surprisingly, the net effect of R&D is not significant in high-tech industries. Policy implications are derived from the findings.

贸易政策不确定性对软件和集成电路企业经营风险的影响

利用沪深A股的软件和集成电路上市公司样本，实证检验贸易政策不确定性对中国软件和集成电路企业经营风险的影响。结果发现，贸易政策不确定性上升总体上将加剧软件和集成电路企业经营风险。进一步区分“企业-区域-行业”维情境差异检验发现，上述结论仅在融资约束程度较高、地区市场化水平较低、行业景气程度较差时显著。说明在中国经济外部环境更趋复杂严峻和不确定的情况下，软件和集成电路企业经营面临贸易政策不确定性的负面影响，并存在情境差异。据此提出有关降低贸易政策不确定性、确保企业经营安全与高质量发展的策略建议。     

日本流通结构变化特征研究

20世纪90年代以来,日本流通结构发生了重要的变化,主要表现为零售组织结构从众多小规模分散性构造向大中小比例适当、大规模集中性的构造转换、批发环节短缩化、物流组织社会化、流通业态多样化、流通企业市场竞争多样化、流通渠道扁平化和流通者主导化等特征。这些变化特征对日本经济效率化和经济结构改革将产生重要影响。     

Is Uniform Money Always Better than Separate Monies?

Previous studies that compare a uniform money with separate monies used models in which money is the only asset and in which individuals hold either zero or one unit of money. Here, the comparison is made using a model in which money coexists with a higher-return asset and in which individuals are permitted to hold richer portfolios of assets. The results show that a general conclusion is not possible. A uniform money has a higher expected utility than do separate monies in many examples. However, when the discount on bonds and uncertainty about the nationality of the trading partner are sufficiently high, then there are examples in which separate monies are better.

Water supply and sanitation in urban South Africa: Getting it right during the transition and beyond

Water and sanitation institutions face major challenges to extend services to those who do not yet receive them, while maintaining financial viability and sustainability, and safeguarding the environment. Meeting these challenges effectively will require that institutions are rationalised; that sensible minimum standards for levels of service and appropriate goals for levels of service are established; that sound investment programmes are set up; that rational tariff policies are implemented; that capital finance is raised effectively; that institutional capacity is developed and the customer interface transformed; that appropriate legislation and methods of monitoring performance are developed; and that compromises on environmental issues are based on well‐informed analysis. Policy proposals in these key areas are put forward in this article to stimulate debate and to guide institutional transformation during the transition and in the longer term.
