University patents,R&D competition,and social welfare

Although university patenting has increased dramatically over the past three decades, debates persist regarding the broad economic implications of the phenomenon. This article examines the social welfare implications of university patenting in a model of R&D competition in which firms develop innovations on the basis of the disclosure of a university invention. When such disclosure does not preempt the patenting of downstream innovations, university patenting enhances social welfare only if a regime of open access to university inventions is characterized by excessive aggregate R&D from the viewpoint of social welfare. When the university invention disclosure preempts patenting on firms’ innovations, the nature of the open access equilibrium in the R&D market depends on the threat of imitation ex post. Only when the threat of imitation is sufficiently strong firms will not invest in downstream R&D in the open access regime. In this case, university patenting promotes R&D investment and increases social welfare.     

中国财政竞争与地方公共支出结构分析

This article examines the impact of intergovernmental fiscal competition on local public expenditure in China under current performance assessment system in which GDP is a critical factor. First, we present the assignment of public goods and tax burden and the share of foreign direct investment (FDI) of 30 provinces, and we find that current fiscal competition in China has taken the form of public expenditure improvement accompanied by preferential tax policies. Second, we regress the share of FDI on different components of provincial public expenditure, and find that the share of FDI is correlated negatively with the public service, tax burden and health care service while positively with infrastructure development. Therefore, FDI-based infrastructural investment crowds out public services investment, which fails to support the view that fiscal competition improves social welfares.     

Measuring China's innovative capacity: a stochastic frontier exercise

We adopt a stochastic frontier analysis of innovative activity to disentangle countries’ patenting capacity from patenting efficiency. We analyse the determinants of innovative capacity of a set of 26 OECD countries plus China, over the period 1992–2007, to show if and how China's technological activity is growing faster than commonly held as compared to the most innovative countries of the world. Our results highlight that both internal and external elements jointly contribute to enhance countries’ innovative capacity and efficiency. In particular, while government-funded R&D is more important for innovative capacity, privately funded R&D as well as foreign direct investments (FDIs) affects technical efficiency (TE). Moreover, as for the whole set of countries, FDIs seem to exert a resource-seeking role (as they negatively affect TE), this does not happen for China, where FDIs exert a positive effect. Results are robust to the use of alternative measures of innovative inputs (such as higher education expenditure in R&D and R&D personnel, but also FDI flows rather than stocks). Finally, human capital measures are generally not very effective in enhancing patenting efficiency, apart from tertiary education.     

Does a strong patent regime discourage innovation?

Does a strengthening of the patent regime impact R&;D expenditure? For the US semiconductor industry, a strengthening of the patent regime in the 1980s was followed by a sharp increase in patenting but had almost no impact on R&;D expenditure. This paper attempts to understand this patent paradox by taking some of the industry features into account. We present a model of invention and product development in complex industries where product development involves putting together a large number of inventions and where licensing of patentable inventions is common. While a stronger patent regime leads to higher patenting in both in presence and absence of licensing, the positive relationship between patenting and R&;D is weakened in presence of licensing since licensing provides an alternative way of accessing inventions. A stronger patent regime, therefore, may only create weak incentives to increase R&;D, while strongly increasing patenting activities in such an industry.     

The effect of an anticipated tax change on investment in Britain

The response of manufacturing investment in equipment to a pre-announced change in the corporate tax rate is found to be consistent with cost-minimising behaviour, but the time-profile of the induced changes in aggregate expenditure is considerably more complex than the standard analysis suggests.     

Infrastructure Investment and Maintenance Expenditure: Optimal Allocation Rules in a Growing Economy

This paper studies the allocation of public expenditure between infrastructure investment and maintenance in an endogenous growth framework. In the basic model, maintenance spending affects both the durability and efficiency of public capital. The balanced growth path is derived and transitional dynamics associated with a revenue-neutral increase in expenditure on maintenance are analyzed. The model is then extended to account for the possibility that public spending on maintenance affects also the durability of private capital. The growth-maximizing tax rate and share of infrastructure investment are calculated in both cases. First- and second-best welfare-maximizing solutions are also discussed.     

地市级地区间基本建设公共支出的相互影响

本文考察中国地市级地区间基本建设公共支出相互影响的机制和特征,主要包括溢出效应和竞争效应。由于地市级基本建设支出的正外部性,溢出效应使得相邻地区基本建设支出间负相关;由于中国特有的地方官员激励结构,地区间经济增长的竞争会导致基本建设公共支出正相关。本文使用中国地市级地区2002—2005年数据检验这两个影响渠道。经验分析发现了溢出效应和竞争效应存在的证据。     

The Causality Between R&D And Investment

The aim of this paper is to investigate the relationship between R&D expenditure and investment in machinery and equipment in order to test for causality. New growth theory emphasises the role of R&D in creating blueprints needed to produce new capital goods implicitly assuming causality running from R&D to investment. Other recent studies using firm level data have investigated the relationship between innovative activity and investment in fixed capital. In this paper we use aggregate data from the US economy on R&D expenditure in the industrial sector and aggregate investment in machinery and equipment. Standard Granger causality tests, together with the Hsiao version, are then performed, showing that causality runs from R&D to investment. In addition we perform a cointegration analysis allowing a test of possible long-run feedbacks. This dynamic representation shows that any feedback between investment and R&D is only significant in the long run.     

Effects of Public Infrastructure on Cost Structure and Productivity in the Private Sector

This paper examines the effects of public infrastructure on the cost structure and productivity in the private sector in Australia. Translog cost functions incorporating public capital infrastructure are estimated for the aggregate private sector as well as for seven broad industry groups using annual time series data for 1968/69–1995/96. The effects of public infrastructure on productivity are measured in terms of both cost-saving and output-augmenting measures. The empirical results suggest that public infrastructure has a positive and significant impact on productivity in private sector industries. Public capital serves as a substitute for both private capital and labour. The rates of return to public capital are significant and vary over the sample period.     

Economic policy,the new economy and the social rate of return to R&D in UK manufacturing

This article focuses on the question of whether public policy changes and/or the new economy have influenced the social returns to R&D expenditure in UK manufacturing over the three decades up to the end of the millennium. The basic methodology is reasonably straightforward, to estimate a production function in which, in addition to labour and fixed capital, R&D appears separately in a form that directly enables estimates of the social return to investment in knowledge and how it has changed over time. The results suggest that neither changes in government R&D policy nor the new economy have raised social returns to R&D.     

财政收入集权增加了基层政府公共服务支出吗?以河南省减免农业税为例

很多研究表明,中国式分权导致了地方政府财政支出结构偏重基础设施建设,忽视公共服务和人力资本投入。免征农业税和相应的转移支付降低了基层政府的财政独立性,其影响与上述政策结果相似。利用河南省108个县级单位2001—2008年的面板数据,本文对减免农业税后的财政支出进行了实证检验,发现受到免征农业税影响较大的县农业支出显著增加,对教育的投入显著下降。由于前者主要是由新农村建设等政策压力造成的,这说明财政收入集权强化了那些易于考核的政策目标的执行力度。     

The impact of fiscal and political decentralization on local public investment in Indonesia

We investigate the effects of the fiscal, administrative and political decentralization process in Indonesia on budget allocation at the sub-national level. We find that after the large-scale expenditure decentralization of 2001, districts with relatively lower levels of public infrastructure started to invest significantly more in health and physical infrastructure, although not in education infrastructure. At the same time, we also see a tightening of the budget constraint in districts where the democratically elected government heads took over already before gaining fiscal powers. Finally, our results document decreases in public investments under directly elected district heads, showing no beneficial effects of direct elections on investment targeting.     

基础设施投资对社会其他部门投资影响效应

基础设施投资在经济发展中起着十分重要的作用,直接影响着经济发展的速度和质量。文章通过建立计量模型,运用1993—2003我国30个省市(自治区)的面板数据,研究了我国基础设施投资对社会其他部门投资的影响。结果发现基础设施投资对社会其他部门投资具有明显的挤入效应,其中西部地区最大,中部地区次之,东部地区最小。最后提出政策建议:提高财政支出效率,加快基础设施领域改革,加快西部地区基础设施建设。     

财政支出竞争与省际基础设施建设趋同性研究

本文认为贫穷省份和富裕省份的基础设施设施建设存在趋同现象,这种趋同性趋势主要源自地方政府间的财政支出竞争,在财政分权的模式下,地方政府迫于强烈的发展意识和政绩需要,往往将基础设施建设作为工作的重心,在财政支出中强调基础设施投入并与其他平级政府进行攀比和竞争。     

Public Capital Formation and Regional Development in Spain

This paper uses a vector autoregression (VAR) approach to evaluate the effects of public investment on private sector performance in Spain. Empirical results suggest that public investment positively affected private investment, employment, and output at both aggregate and regional levels. The regions that benefited the most from public investment in the last two decades were Cataluña, Madrid, and Pais Vasco. These regions are among the largest economic areas in the country and among the ones with the highest GDP per capita. Accordingly, public investment, while an important factor for aggregate economic growth, has also been a source of increasing regional asymmetries.     

Does Taxation Stifle Corporate Investment? Firm‐Level Evidence from ASEAN Countries

This article conducts a firm‐level analysis of the effect of taxation on corporate investment, using large‐scale panel data on non‐financial firms over the period 1990–2014, and controlling for macrostructural differences among ASEAN countries. We find a significant degree of persistence in fixed investment over time, which varies with firm characteristics, such as size, growth prospects, profitability and leverage. The non‐linear estimations indicate that taxation facilitates business investment (possibly by enabling public investment in infrastructure and human capital, and the proper functioning of government institutions), but this effect turns negative and stifles private investment growth as the tax burden increases.     

Regional infrastructure and firm investment: theory and empirical evidence for Italy

The authors model the channels through which public expenditure on infrastructure influences firm value and shapes its investment decisions via both adjustment costs and marginal profitability of capital. The authors test these hypotheses using a large panel of Italian firms. Empirical results show that infrastructure interacts with revenues and costs in shaping firm??s capital profitability and influences its adjustment costs. Finally, the authors find that infrastructure expenditure contributes to the reduction of the economic gap between the North and the South of Italy. These effects vary across regions and sectors.     

Changes in the fiscal stance and the composition of public spending

We consider the impact of both cyclical and structural changes in the fiscal stance on public spending composition for a panel of EU countries, including individual components of public investment. We find that both cyclically induced and structural changes in the fiscal stance affect the composition of public spending, with fiscal tightening of both types increasing the relative share of investment and loosening favouring consumption expenditure. Of the components of public investment, infrastructure and redistribution respond to cyclical changes in the fiscal stance, while investment in hospitals and schools responds most clearly to structural changes.     

EDUCATION AND ECONOMIC DEVELOPMENT-THE CANADIAN CASE*

This study assesses the relationship of education and economic growth, economic development and economic progress in aggregate, in structural and in micro-economic terms on the basis of one hundred years of Canadian experience. Education is considered as a factor of input. The contribution made by knowledge resulting from additional education expands the capacity to produce, and increases the demand for goods and services and the desire for greater leisure. The dual function of education is stressed: the demand and supply effect. Education is examined both as a cause and a consequence of economic growth, economic development and economic progress, through its contribution to the quality of the labour force, earning capacity, both individual and national, productivity, the rate of economic growth and the character of economic development. The Canadian experience suggests that educational progress generally occurred in line with economic development during the first eight decades, with the real take-off in educational advancement only occurring in the last two decades, when the nation reached the stage of technological maturity and high mass-consumption. Among the reasons for the lower ratio of gross national product devoted to education in the first eight decades were the low priority attached to education, the emphasis on investment in physical capital because of its shorter pay-off period than investment in human capital, and the heavy reliance on a substantial flow of immigrants who had obtained their education and training abroad. A distinct change occurred, however, in the last two decades, partly as a result of new technological challenges and partly as the result of changes in private and public attitudes, as the recognition of the rewards of education in terms of individual advancement and social progress led to a greater willingness to devote an increasing proportion of the nation's resources to investment in human capital, long pay-off periods notwithstanding.     

Inflation targeting and the composition of public expenditure: Evidence from developing countries

An important literature shows that inflation targeting (IT) adoption improves fiscal discipline. Our impact assessment analysis performed in a large sample of 89 developing countries over three decades shows that this favorable impact covers a composition effect: IT adoption is found to reduce more current expenditure compared with public investment in IT countries relative to non-IT countries. This finding is robust to various alternative specification, related to the structure of the sample, the measurement of the IT regime, or the estimation method. Consequently, aside from its acknowledged benefits for monetary policy goals, IT appears as an efficient tool to strengthen fiscal policy in developing countries towards lower and more productive public expenditure.
