公共产品的私人供给--以开放源代码软件开发为例

公共产品如何供给的问题,是福利经济学、财政学等关注的焦点问题。在什么情况下,用什么样的激励制度才能促进私人供给公共产品的积极性,长期以来悬而未决。近期出现的开放源代码软件为我们提供了新的案例。开放源代码软件倡导自由和开放的精神,完全打破了以往的商业惯例。开放源代码软件符合公共产品的基本特征,对开放源代码软件特殊供给方式的研究,能使我们在探讨公共产品的私人供给方面开拓更广的视野。同时对开放源代码软件生产过程的研究,还揭示出一种新型的生产关系正在逐步形成。     

Designing a forecasting analysis to understand the diffusion of open source software in the year 2010

Open source software (OSS) is being considered the new paradigm of software distribution. As contrasted with the traditional software marketing model, OSS pursues the freedom to have access to open source and offers several advantages to enterprises. These advantages include saving costs related to Information Systems and Technologies (IS/IT) and the possibility of adapting to changing organizational requirements. However, the recent forthcoming of OSS prevents us from knowing the real impact it has today on social and organizational fields. Having considered this obstacle, the authors have defined a foreseeable setting for OSS diffusion and adoption by means of a forecasting study based on the Delphi method for the year 2010. The findings reveal the levels of OSS diffusion for this year according to the main applications, geographic regions and industries. In a complementary manner, the authors have studied the elements of success as well as the most relevant obstacles for diffusing and adopting technological solutions based on OSS.     

The knowledge management strategy and the formation of innovative networks in emerging industries

This paper presents an agent-based simulation model with local network externality to analyze strategic interactions over investment on new economic knowledge. R&D knowledge flows and spillovers are the results of non-cooperative games played between neighboring agents in the model. The model demonstrates a situation where no agents have incentives to hide their economic knowledge, a situation that is observed in open source software development projects. The likelihood of obtaining a stable situation where new economic knowledge is openly shared is increased when heterogeneity of agents is introduced.      

Depreciation and intergenerational altruism in the private provision of public goods

The static model of the private provision of public goods is refuted by empirical and experimental evidence which shows that contributions are above the levels predicted by the theory. The model is reconsidered here in an intertemporal framework that allows the formation of a stock of public good over time and admits intergenerational altruism into preferences. Both of these factors affect the level of private provision. An intertemporal version of the Samuelson rule is derived and it is shown that, for some parameter values, the provision level determined by this is matched by private provision. For other parameter values, it is shown how a system of taxation can achieve the optimum.

Determinants of cyclical properties of the price-cost margin in US manufacturing industries

Supergame theoretical predictions tell that oligopoly pricing may be procyclical or counter-cyclical. Industry by industry analysis shows that the speed of industry growth and the size of fixed cost are crucial in distinguishing characteristically counter-cyclical industries from procyclical industries. Counter-cyclical industries are characterized by high growth of demand and low fixed costs. Procyclical industries are characterized by low growth of demand and high fixed costs.     

Technological catch-up: Gradual diffusion of technology and convergence in the neoclassical growth model

In this paper, I study the effects of the international gradual transmission of technology on the convergence processes among countries. In this way, the international gradual diffusion of technology makes possible a greater potential improvement capacity to the less developed country in its technological level. When this hypothesis is included in the Solow-Swan growth models, the paper shows that the convergence hypothesis will now be maintained only in the growth rates since a gap in income levels will remain in the long run. That conditional convergence will be explained by two factors: the diminishing returns for cumulative factor and the gradual diffusion of technology. I will finish this paper with empirical evidence of these two factors explaining convergence.     

交易成本、政府级次与财政体制改革

由于受交易成本的制约,管辖范围小、涉及人数少的"小政府"作为降低公共产品供给交易成本的制度安排首先得以形成.而后,为降低受益范围超出小政府辖区的公共产品供给的交易成本,更高层次的政府得以出现.政府级次化降低了公共产品供给的横向交易成本却增加了纵向交易成本,当横向交易成本的减少额与纵向交易成本的增加额在边际上相等时,政府级次达到均衡.由此看来,基层政府具有"逻辑先在性",采用"自上而下"分权的思路来构建财政体制是值得商榷的.财政体制的构建从逻辑上讲应该是"自下而上"授权而不是"自上而下"分权.     

Modelling the faddish, fashionable and efficient diffusion of agricultural technologies: A case study of the diffusion of wool testing technology in Australia

This study investigates the nature of innovation diffusion in an agricultural context. The dominant agricultural diffusion models assume that an economically rational choice is made to adopt or reject agricultural technologies. However, recent studies of agricultural innovation highlight the ‘irrational’ and potentially ‘inefficient’ nature of the diffusion in this context. To investigate how and why agricultural technologies are adopted or rejected, we examine the diffusion of wool testing technologies in the Australian wool industry using the Bass diffusion model and Abrahamson's diffusion and rejection typology. The results show that diffusion of agricultural innovation is not simply an efficient choice made to close observable performance gaps. The findings suggest that the adoption of inefficient innovations and the rejection of efficient innovations can be driven by an adopter's social context, powerful external influences and imitation within an adopter group and that these drivers change over time, suggesting an evolutionary social process underlies the diffusion of agricultural technologies.     

Market thickness,sunk costs,productivity, and the outsourcing decision: an empirical analysis of manufacturing firms in France

Abstract This paper presents an empirical analysis of outsourcing behaviour by French manufacturing industries. It focuses on the effects of market thickness, sunk costs, and the productivity of firms on the outsourcing decision. I estimate a dynamic probit model where outsourcing decision is linked to past outsourcing behaviour. The results show that outsourcing is a persistent strategy adopted by large firms and suggest the presence of significant sunk costs associated with outsourcing. The results also show that market thickness reduces search costs and enhances the establishment of outsourcing relationships.     

An analysis of the effect of the economic situation on modeling and forecasting the diffusion of wireless communications in Finland

In this paper, the diffusion of wireless communications in Finland is studied. The objectives are to find factors which have affected the diffusion process and to forecast the diffusion of wireless communications in Finland. The diffusion process is based on the epidemic diffusion theory. The data consists of annual wireless subscribers of networks based on Nordic Mobile Telephone (NMT) and Global System for Mobile Communications (GSM) standards in 1981-1998. The data is fitted into the logistic model by means of nonlinear least squares after writing two parameters of the logistic model as functions of certain variables. The results show that the economic situation has affected the relative growth rate, and that the wireless network coverage has affected the number of potential adopters. By extrapolating the logistic model, a forecast with a confidence interval of wireless communications subscriber rates in Finland is made. The forecast shows that the final penetration rate will be some 91.7% in 2009. The model predicts the actual figures of year 1999 very accurately. Finally, the time derivatives of the diffusion process are analyzed; they clarify the effect of economic situation on the diffusion.     

The Evolution and Devolution of Bank Regulation in the United States

Development economics is understood as a postwar phenomenon without antecedents. Yet, Veblen's contribution to development economics was once widely disseminated and acknowledged. Veblen's evolutionary economics centered on historically relative and limited truths applicable to specific cultures. Veblen's growth theory is a theory of economic development: quantitative accumulation is significant because it engenders qualitative change. Veblen's analysis of the harnessing of the economic potential centers on the ability of a society to successfully introduce scientific and technological advances, giving rise to increasing returns as the surplus is invested in industrial activities. Veblen presented oblique comments and startling insights in a non-empirical manner.     

Technology diffusion,spatial effects and productivity growth in the Chinese provinces

This paper investigates spatial spillover effects of productivity in China. We set up a model in which a Chinese province achieves productivity growth by taking advantage of productivity spillovers from the world frontier and from other Chinese provinces. By using fixed effects and GMM panel data methods, we show that productivity growth in an inland province in China can be partly attributed to productivity spillover effects of other provinces. We also show that provincial human capital plays an important role in determining the magnitude of these spillover effects.     

Productivity growth in British manufacturing: spatial variation in the role of scale economies,technological growth and industrial structure

This paper investigates the role of scale economies, technological growth and industrial structure in creating spatial variation in manufacturing labour and Total Factor (TFP) productivity in Britain. Separate estimates of a translog specification are presented for British manufacturing firms located in defined areas of the country over the period 1994–1998. The results show that TFP change due to scale economies and technological growth has been of much less important in influencing the output growth of manufacturing firms than input growth or industrial structure. Regarding the components of TFP, technological growth has been the dominant force at play. The analysis of average labour productivity identifies shifts to other factors of production and industrial structure as being the main determinants of change, scale economies appear to have had a marginal role. The results identify spatial patterns indicating that more favourable locational effects arise for firms in areas adjacent to large urban centres, rather than for those located within cities, on the extreme periphery of the urban hinterland, or in rural areas and smaller towns.     

International trade,technological shocks and spillovers in the labour market: a GVAR analysis of the US manufacturing sector

We empirically analyse the response of labour market related variables in the US manufacturing sector to various shocks, notably to trade openness and technology, as well as examining spillovers from industry-specific labour market shocks. The econometric approach involves an application of the recently developed Global Vector Autoregression methodology of Dées et al. (2007 Helbling, T, Jaumotte, F and Sommer, M. 2006. How has globalization affected inflation?. IMF World Economic Outlook, April: 97–134.  [Google Scholar]) to 12 manufacturing industries over the period 1977–2003. The framework allows us to analyse the response of a standard set of labour-market related variables (employment, real compensation, productivity and capital stock) to exogenous factors (a sector-specific measure of trade openness, a common technology and oil price shock), along with industry spillovers using specific measures of manufacturing-wide variables for each sector. Generalized impulse responses indicate that increased trade openness negatively affects real compensation, has negligible employment effects and leads to higher labour productivity. These impacts, however, are relatively weaker than those induced by technology shocks, with the latter positively and significantly affecting both real compensation and employment. There is also evidence of positive spillovers across industries from sector-specific employment and productivity shocks. Impact elasticities suggest strong intra-sectoral linkages for employment and capital stock formation, contrasting with weak linkages for what concerns real compensation and productivity.

Input substitution,economies of scale and productivity growth in the US upholstered furniture industry

Cost, factor demand and productivity growth are considered in the upholstered furniture industry over 1958–87. Factors are divided into labour, capital and materials. It is found that all inputs are substitutes in production although substitution elasticities are small. Factor demand is price-inelastic for all inputs. The industry operates around minimum average cost. Productivity growth is small but significant. The results indicate that labour will continue to be important in the industry. However, regional comparative advantage is not related to labour alone; the results suggest that policies to attract or retain the industry must consider the low degree of factor substitution.     

Budget impact analysis of niraparib and olaparib for maintenance treatment of platinum-sensitive,recurrent ovarian cancer in the US

Aims: This study aimed to evaluate the budget impact of niraparib and olaparib in patients with platinum-sensitive, recurrent ovarian cancer from a US third party payer perspective.

Materials and methods: A budget impact model was constructed to assess the additional per member per month (PMPM) costs associated with the introduction of niraparib and olaparib, two poly ADP-ribose polymerase ribose polymerase (PARP) inhibitors recently approved to be used in platinum-sensitive, recurrent ovarian cancer patients with and without a gBRCA mutation. The model assessed both pharmacy costs and medical costs. Pharmacy costs included adjusted drug costs, coinsurance, and dispensing fees. Medical costs included costs associated with disease monitoring and management of adverse events from the treatment. Epidemiological data from the literature were used to estimate the target population size. The analysis used 1-year time frame, and patients were assumed on treatment until disease progression or death. All costs were computed in 2017 USD. One-way sensitivity analyses were conducted to evaluate the model robustness.

Results: In a hypothetical plan of 1,000,000 members, 206 patients were estimated to be potential candidates for niraparib or olaparib maintenance treatment after applying all epidemiological parameters. At listed 30-day supply WAC prices of $14,750 for niraparib and $13,482 for olaparib, budget impacts of these two drugs were $0.169 PMPM and $0.156 PMPM, respectively, most of which were contributed by pharmacy costs. Sensitivity analyses suggested that assumptions around market share, platinum-sensitive rate after first treatment, and WAC prices affected results the most.

Limitations: In this model, it was assumed that adopting niraparib and olaparib would not affect utilization of existing medications. Also, the estimated clinical parameters from clinical trials could differ from real-world data.     

The role of ageing in the growth of government and social welfare spending in the OECD

Government expenditure as a share of GDP in the OECD rose at an annual growth rate of 1.02% in the period between 1970 and 1997. Government spending has increased most on functions particularly demanded by elderly population: social welfare, health and defence. Ageing is the main driving force of the growth of government spending, followed by relative prices and population. However, we also find that the other age groups react to ageing, thereby preventing increases in benefits per retired persons and that institutional reforms have been successful at reducing the impact of ageing on pensions in recent years.     

Localized innovation, localized diffusion and the environment: an analysis of reductions of CO2 emissions by passenger cars

We investigate technological change with regard to CO₂ emissions by passenger cars, using a Free Disposal Hull methodology to estimate technological frontiers. We have a sample of cars available in the UK market in the period 2000–2007. Our results show that the rates of technological change (frontier movement) and diffusion (distance to frontier at the car brand level) differ substantially between segments of the car market. We conclude that successful policies should be aimed at the diffusion of best-practice technology, and take account of the different potential for further progress between different segments of the market (e.g. diesel vs. gasoline engines and small vs. large engines).
