Can privatization be a catalyst for environmental R&D and result in a cleaner environment?

In this paper we explore whether privatization helps to catalyze a firm's environmental research and development (ER&D) and improve environmental quality. By defining ER&D as the effort undertaken by a firm to reduce its pollution per unit of output, we find in a duopoly framework that privatization cannot catalyze both public and private firms’ ER&D efforts simultaneously; it can increase one but decrease the other firm's investment, or it may even lower both firms’ ER&D investments. Moreover, when production causes severe environmental damage, or the imposition of environmental taxes poorly internalize the pollution externality, privatization may result in a poorer environment. For the sake of having a cleaner environment, policy-makers can impose higher environmental taxes on a highly polluting industry when it is being privatized.     

Industrial Policy and Firm Heterogeneity

Our concern in this paper is with firm-specific industrial policy. When R&D subsidies or taxes are differentiated among firms, the question arises as to which firms in an industry should receive such support. We analyze a situation where firms differ in their R&D technologies in two distinct ways: in the costs of performing R&D activities and in the output obtained from such activities. We find that the optimal firm-specific industrial policy is affected differently by the two sources of firm heterogeneity. Furthermore, a change in a firm's R&D productivity has an ambiguous effect on the optimal policy towards the firm.

Mixed Duopoly,Merger and Multiproduct Firms

The literature on mergers has extensively analyzed the decision to merge by private firms, but it has not considered the decision to merge by private and public firms. We assume that when a private firm and a public firm merge (or when one of them acquires the other), they set up a multiproduct firm in which the government owns an exogenous percentage stake. In this framework, we show that the decision to merge by firms depends on the degree to which goods are substitutes and on the percentage of the shares owned by the government in the multiproduct firm.     

融资结构、企业异质性与研发投资*——来自中国上市公司的经验证据

企业融资结构影响研发投资强度吗？是否存在能促进企业研发投资强度提升的最优融资结构？对不同类型的企业而言,最优融资结构是否存在差异呢？本文运用中国上市公司2007—2015年的面板数据进行实证研究,结果表明：（1）企业越偏向于股权融资,研发投资强度就越高;（2）存在有利于促进研发投资强度提升的最优融资结构;（3）企业的最优融资结构随企业所属的产业性质、股权集中程度、银企关系强度及所有权性质的不同而呈现显著的差异。本文的研究发现有助深入理解融资结构与研发投资的关系,也为决策者制定宏观金融结构优化政策提供了来自微观企业层面的证据。     

Outsourcing of innovation

This paper looks at the outsourcing of research and development (R&D) activities. We consider cost reducing R&D and allow manufacturing firms to decide whether to outsource the project to research subcontractors or carry out the research in-house. We use a principal-agent framework and consider fixed and revenue-sharing contracts. We solve for the optimal contract under these constraints. We find that allowing for revenue-sharing contracts increases the chance of outsourcing and improves economic efficiency. However, the principal may still find it optimal to choose a contract that allows the leakage to occur—a second-best outcome when leakage cannot be monitored or verified. Stronger protection of trade secrets can induce more R&D outsourcing without inhibiting technology diffusion and increase economic efficiency, as long as it does not significantly lengthen the product cycle.

R&D expenditures and firm growth – is small beautiful?

ABSTRACT

This paper examines how efficiently different groups of firms use their R&D expenditures. To this end, it investigates how the empirical relationship between firms' R&D expenditures and their sales growth varies with different values of firm size, firm age, and the number of firms in the respective industry. Using panel data for Switzerland ranging from 1995 to 2012, the paper finds that smaller, more mature firms show a more positive relation between R&D expenditures and sales growth than both relatively larger or younger firms. The paper argues that, on the one hand, these firms can benefit from various small size advantages in the R&D process, such as more motivated researchers, caused by a stronger connection to the firm's fate. On the other hand, these firms can also benefit from a well-established R&D department that allows absorbing the latest technological developments. The paper further finds that industries consisting of many small firms show a more positive relation between R&D expenditures and sales growth than industries consisting of only a few large firms. The intuition behind this result is that industries consisting of many small firms imply more independent innovative trials, which then together result in a higher probability of discovering successful innovations. In sum, the paper finds that groups consisting of a large number of small, more mature firms spend their R&D in the most efficient way.     

Does R&D spending boost tangible investment? An analysis on European firms

This article investigates the relationship between firm’s R&D intensity, expressed as R&D expenditure over sales, and investment intensity in tangible assets. It is commonly acknowledged that R&D requires additional physical investment to be implemented. R&D increases a firm’s productivity and return to tangible investments, thus, providing to the firm incentives to bear high tangible capital costs and to invest more. This represents a crucial issue for a firm’s growth, particularly considering the strong interaction between physical capital accumulation and technological progress. The analysis is based on a large sample of manufacturing firms across seven European countries in the period 2007–2009. Since the sub-sample of firms performing R&D might not be random, there may potentially be an endogeneity issue. The analysis also considers that firms may decide to spend on R&D and investment in physical capital simultaneously. The questions of both endogeneity and simultaneity are dealt with by employing an instrumental variable two-step procedure. We find a positive and significant impact of R&D intensity on firms’ tangible investment intensity. The econometric results highlight the importance of financial factors, particularly with respect to firms’ internal resources. Exposure to international trade has a negative impact on investment, possibly depending on the time-span of the sample used.

THE BENEFIT OF REDUCED COMPETITION AND THE COST OF INFORMATION RENT UNDER OUTSOURCING

We analyse the cost and benefit of outsourcing with adverse selection in a duopoly by comparing outsourcing with in‐house production in terms of the manufacturer’s expected profit. When two manufacturers faced with ex ante cost uncertainty compete in a differentiated duopoly, outsourcing brings about a benefit in terms of reduced competition, while it entails the cost of information rent. We show that the manufacturers always choose in‐house production in Cournot and Bertrand competition, when outsourcing and in‐house production follow the same ex ante cost distribution. When the manufacturers compete in Cournot fashion, the cost of information rent always exceeds the benefit of reduced competition under outsourcing. On the other hand, when they compete in Bertrand fashion, it is possible that even if the benefit of outsourcing exceeds the cost, both manufacturers cannot choose outsourcing.     

研发创新抑制波动机制分析*——基于企业生产供给波动视角

本文基于种类扩展型技术进步框架构建了理论模型,分析研发创新对企业层面生产供给波动的影响效应以及其作用机理,并利用中国制造业企业数据对理论模型进行验证。本文发现,研发创新带来的更多技术种类能够在一定程度上抵御生产波动的风险,企业研发创新强度越大、全要素生产率越高,则企业产出波动性和生产率波动性越小。进一步研究发现,研发投入是通过扩展技术种类范围、提升全要素生产率间接地抑制波动,而研发产出会对企业层面波动产生直接和间接的抑制作用。因此,本文揭示了“创新性毁灭”之外研发创新影响企业层面波动的另一种机制,为改善供给状况、平抑实体经济波动提供了政策启示。     

家族企业的控制目标、盈利目标与研发投入

以2011—2016年中国沪深两市家族企业为样本,采用二手数据Tobit回归方法,研究了家族企业控制目标和盈利目标的实现与否对研发投入的影响。结果显示:供应商对家族企业的威胁越大,家族企业管理者为了实现控制目标越倾向于增加研发投入;家族企业管理者对盈利目标和控制目标的重视遵循注意力顺序理论,即当盈利目标未实现时,家族企业管理者更关注盈利状况,较少关注控制威胁,因此会减少研发投入;当盈利目标实现后,家族企业管理者才关注控制威胁、增加研发投入;家族企业的资源禀赋优势有助于控制目标的实现。
