资本要素市场化改革、对外直接投资与技术创新绩效

对外直接投资对母国产业的技术创新具有反哺促进效应,但同时受资本要素市场扭曲的调节作用影响。本文运用2003~2016年的面板数据,设定双因素基准模型并进行东、中、西部地区分样本回归以检验资本要素市场扭曲对OFDI的技术创新的调节作用。结果发现:OFDI通过逆向技术溢出促进了母国的企业技术创新绩效。同时,资本要素市场扭曲抑制了OFDI反哺技术创新绩效的正向作用,且资本要素市场扭曲对OFDI的技术创新的调节效应存在地区差异性。因此,深化要素市场化改革,调整对外直接投资结构和优化营商环境,是实现OFDI协调发展以推动技术创新绩效提升的有效途径。

收入分配对资本积累及投资结构的影响--我国二元结构下的三部门均衡模型

本文以我国二元结构为背景，从收入分配的角度，建立了资本积累、投资结构决定的数理模型，并以此分析资本积累、投资结构的影响因素。模型参数分析的主要结论是：①任何导致总消费需求上升的变化都会通过提高轻工业的供给能力而提高其资本存量的相对比重，以及资本积累的相对比重（即抑制投资重化）；②任何提高消费品供给能力的技术进步通常都将降低稳定状态下轻工业资本存量，以及资本积累的相对比重（即促进投资重化）。     

我国的收入分配发展趋势是否为倒U形

阐述了国内外学者对库兹涅茨"倒U假说"所持的观点和认识。用我国的实际数据对库兹涅茨"倒U假说"进行了检验,认为我国的收入分配基本上不符合倒U形状,不能靠经济增长来解决收入差距的拉大问题;收入现状的改善需要政府政策的支持。     

基于诱因的技术创新模式研究

<正>任何一项活动的开展总是参与该活动的行为主体在一定的诱导因素作用下发生的,技术创新活动同样需要相应的诱导因素来诱发。技术创新诱导因素的研究,是技术创新理论研究的核心内容。在技术创新的诱导因素中,包含着多重诱导要素,各种要素对技术创新起着不同的作用,因而,就技术创新的诱因问题,产生了不同的技术创新诱因模式。但这些要素并非孤立地发挥作用,而是在相互作用的基础上形成技术创新的复合诱导因素。     

公共资本生产率的比较研究——基于长三角21城市公共资本边际生产率的实证分析

近10年来长三角的政府公共投资（分配）过多地流向了上海、苏州、杭州、南京等核心城市，使这些城市的人均公共资本拥有量大幅上升，从而引发了其边际生产率递减情况的发生。但它们的资本利用效率或技术创新水平没有明显提升（或下降），不足以抵消其资本边际生产率下降的趋势。对这些大城市的经济发展来说，公共投资对其经济增长的意义已经在数量上表现得不明显，但对正处于经济快速增长期且资本边际生产率呈递增态势的长三角外缘中小城市而言，公共投资却有着积极意义。

人力资本与基础设施投资的动力学分析

本文将公共支出引入一个两部门城市化和内生增长模型,由模型导出的人力资本跨时转移条件方便我们分析经济的过渡动力学行为。数值解结果表明,在物质资本报酬递减的情形下,公共支出的部门间配置由经济过渡动力内在地确定和稳定;如果物质资本表现出某种程度的报酬递增,公共支出的部门间配置将表现出内在不稳定。动力学分析表明,公共支出与经济增长之间存在非线性关系,换言之,存在促进经济增长的最优税率或最优公共支出比例。     

At their wits’ end? Economic stress,motivation and unethical judgement of public servants

ABSTRACT

Through an interdisciplinary approach, this paper addresses the scarcity of research that assesses economic stressors, public service motivation (PSM), work motivations, and unethical judgement in the public square. We argue that motivations have a direct relationship with the acceptance of unethical behaviour, but that economic stress (defined as financial stress and job insecurity) may influence this relationship both direct and indirectly. Using data from the European Social Survey, we develop a path model to test these hypotheses. We find that PSM and work motivation influence unethical judgements, and perceived economic stressors play an indirect role through their relationship with work motivations. Implications of the findings are discussed.     

Growth, public investment and corruption with failing institutions

Corruption is thought to prevent poor countries from catching up with richer ones. We analyze one channel through which corruption hampers growth: public investment can be distorted in favor of specific types of spending for which rent-seeking is easier and better concealed. To study this distortion, we propose a dynamic model where households vote for the composition of public spending, subject to an incentive constraint reflecting individuals’ choice between productive activity and rent-seeking. In equilibrium, the structure of public investment is determined by the predatory technology and the distribution of political power. Among different regimes, the model shows a possible scenario of distortion without corruption in which there is no effective corruption but the possibility of corruption still distorts the allocation of public investment. We test the implications of the model on a set of countries using a two-stage least squares estimation. We find that developing countries with high predatory technology invest more in housing and physical capital in comparison with health and education. The reverse is true for developed countries.      

Economic conditions for innovation: Private vs. public sector

The Hicks induced innovation hypothesis states that a price increase of a production factor is a spur to invention. We propose an alternative hypothesis restating that a spur to invention requires not only an increase of one factor but also a decrease of at least one other factor to offset the companies’ cost. We illustrate the need for our alternative hypothesis in a historical example of the industrial revolution in the United Kingdom. Furthermore, we econometrically evaluate both hypotheses in a case study of research and development (R&D) in 29 OECD countries from 2003 to 2017. Specifically, we investigate the dependence of investments to R&D on the economic environment represented by average wages and oil prices using panel regression. We find that our alternative hypothesis is supported for R&D funded and/or performed by business enterprises while the original Hicks hypothesis holds for R&D funded by the government and R&D performed by universities. Our results reflect that the business sector is significantly influenced by market conditions, unlike the government and higher education sectors.     

Research Investment and the Economic Returns To Chinese Agricultural Research

This article measureseconomic returns to research investment in Chinese agricultureusing the production function approach. A stock-of-knowledgevariable constructed from the past research investment is directlyincluded in the production function as an explanatory variablein the production function. Improved rural infrastructure, irrigation,and education are also included as explanatory variables to avoidthe upward bias in the estimates of returns to agricultural research.A two-way variable coefficients technique is used in the estimationto reduce estimation biases due to the remaining measurementand omitted variables problems. Sensitivity analyses are conductedto test the effects of various lag structures on the return estimates.The results show that rates of return to research investmentin Chinese agriculture are high, ranging from 36% to 90% in1997, and the rates are increasing over time.     

The long-run implications of the production smoothing model of inventories: An empirical test

This paper provides an empirical test of the long-run implications of the production smoothing model of inventories, the dominant framework for inventory investment research in the past. Intertemporal models of a firm holding inventories of finished goods predict a long-run relationship between inventories, shipments, factor input prices, and the real interest rate which is tested here using cointegration test procedures. These tests provide little support for the predictions of the production smoothing model. In most of the data sets used, test statistics indicate that inventories, shipments, factor input prices, the nominal interest rate, and the inflation rate maintain a long-run equilibrium relationship but parameter estimates of cointegrating vectors are often implausible, typically rejecting hypotheses implied by structural models of the production smoothing motive for holding inventories.     

Organizational capital and the choice between specialization and diversification

This paper specifies a model in which the preservation of organizational capital is the principal factor motivating corporate diversification decisions. Alternative hypotheses of the determinants of diversification are then subjected to empirical test with data for 96 US industrial firms in the 1967–71 period. Consistent with the model, variables associated with unfavorable expectations on the marginal returns to investment in existing activities proved dominant in explaining ‘desired’ increases in diversification. Alternative explanations, namely, the role of managerial attributes, of absolute advantages of some firms, and of opportunities created by research and development, had more modest explanatory power.     

Allocation of public funds to R&;D: a portfolio choice-styled decision model and a biotechnology case study

A decision problem—allocating public research and development (R&D) funding—is faced by a planner who has ambiguous knowledge of welfare effects of the various research areas. We model this as a reverse portfolio choice problem faced by a Bayesian decision-maker. Two elements of the planner’s inferential system are developed: a conditional distribution of welfare ‘returns’ on an allocation, given stated preferences of citizens for the different areas, and a minimum risk criterion for re-allocating these funds, given the performance of a status quo level of funding. A case study of Canadian public research funds expended on various applications of agricultural biotechnology is provided. The decision-making methodology can accommodate a variety of collective expenditure and resource allocation problems.
