The aim of this study is to analyse whether the receipt of public R&D funding determines firm's R&D strategy selection. This issue is crucial, as previous studies have shown that each R&D strategy is associated to a higher, or lower, innovation performance. We consider three R&D strategies – make, buy, make–buy – and three different sources of public funding – regional, state and other (such as EU). The model estimation is performed through a multinomial logit model with random effects with a sample of 457 large firms for the period 1992–2005, taken from the Spanish Survey of Business Strategies. The main finding is that the source of the funding influences whether firms select the make, buy or make–buy strategy. Additionally, because of the panel structure of the sample, we observe that the effect of public funding on the R&D strategy selection lasts longer for state and regional funds than for other funds. 相似文献

In order to assess damage risk caused by climate change in forest areas, Dempster–Shafer theory of evidence and fuzzy measures were applied to develop a framework for the estimation of economic forest damage. According to the definition of risk supported by the Intergovernmental Panel on Climate Change, a function of hazard and resilience lines of evidence was defined. The results of the hazard and resilience assessment were used to develop an economic framework based on Faustmann studies. The evaluation model, implemented through a spatial analysis procedure, was carried out linking Faustmann formula with hazard and resilience raster maps. The model permitted to estimate in monetary terms two possible costs to be supported: the first one is expressed as the expected damage to the forest crop on the basis of the current obtainable woody assortments and the second one referred to the potential expenses to pay in order to mitigate the risk. Finally, the framework was tested on an area of central Italy (Tuscany region). 相似文献

Frank Gerald Shove was a close friend of Keynes and the other protagonists of the economic debates in Cambridge during the 1920s and 1930s. Shove's influence on those debates is not well documented because he published little and had all his notes destroyed after his death. This paper looks at Shove's most significant contributions to the debates of the 1930s. Attention is concentrated on the debates over increasing returns and imperfect competition. Shove emphasized the complexity of economic phenomena and the need to develop tools to deal with it. He found his analytical and methodological inspiration in Marshall's work. This position led him to clash with younger economists, in particular Joan Robinson, whose work on imperfect competition and whose efforts to achieve rigorous and ‘precise’ results failed, in his view, to capture the working of actual markets. The final section of the paper discusses the similarity of Shove's methodological outlook to that of Keynes. Both were well aware of the need to go beyond Marshall, but they wanted to retain the richness, complexity and realism of Marshall's approach. 相似文献

ABSTRACTThis paper discusses the moderating effect of frugal behavior on the relationship between food package familiarity and the perceived amount of verbal information. Two experiments were conducted on food packaging to analyze two central points: (a) the relationship between food package familiarity and the perceived amount of verbal information and (b) the moderating effect of frugal behavior on this relationship. The studies demonstrate the negative influence of food package familiarity on the perceived amount of verbal information. We demonstrate that the greater (smaller) the familiarity with food packaging is, the smaller (greater) the visual attention to the verbal information will be. Second, we show that frugal behavior moderates this behavior. Our experiment shows that a greater (smaller) tendency toward frugal behavior tends to have a positive (maintain negative) effect on the relationship between food package familiarity and the perceived amount of verbal information. 相似文献

For three years in Bolivia (2002–2005) the INNOVA Project finished researching several technologies for sustainable agriculture, started by earlier DFID-funded projects. Before INNOVA started critics suggested that these technologies should be discarded in favour of a demand survey. Instead, INNOVA kept the existing technologies, but judged the demand for them with several methods (CIAL, sondeo technology fair, and others). INNOVA found that there was demand for some of the technologies, but that a survey would have missed much of the demand, which is implicit. That is, people are not initially aware of all their problems or of all the possible solutions. Over the years, farmers made more specific, sophisticated demands on the technologies, which evolved as a result. Demand and supply of farm technology are like two sides of an unfolding conversation. 相似文献

What is the role of financial speculation in determining the real oil price? We find that while macroeconomic shocks have been the main real oil price upward driver since mid-1980s, financial shocks have sizably contributed since early 2000s as well, and at a much larger extent since mid-2000s. Even though financial shocks contribute 44% out of the 65% real oil price increase over the period 2004–2010, the third oil price shock is a macro-finance episode: macroeconomic shocks actually largely account for the 2007–2008 oil price swing. While we then find support to the demand side view of real oil price determination, we however also find a much larger role for financial shocks than previously noted in the literature. 相似文献

This article analyses management–union–worker relations in a foreign‐owned Moldovan clothing factory. Studies of post‐socialist industrial relations have focused on explaining labour quiescence, advancing ‘path dependence’ and ‘Soviet legacy’ arguments. These draw attention to strong links between management and unions, and weak relations between the latter and workers. We show how the union has, in one case, drawn creatively on Soviet legacies to develop strong articulation between itself and women workers. This was part of a wider adaptive strategy within which the union transformed the meaning of previous functions and developed novel ones. The outcome is a well‐organized representative union capable of challenging management at the negotiating table, as well as on the shop floor. This seems unlikely to be universal but equally unlikely to be unique. 相似文献

This paper addresses a cutting stock problem under typical resource constraints that arise when working centres with nesting capabilities are associated with automatic feeders/stackers. The critical resource is the number of buffers available to host the batches built up by the centre. To cope with it, pattern and batch sequencing problems must be addressed simultaneously. A tabu-search algorithm exploring batch output sequences is proposed. The algorithm never opens more stacks than buffers, respects batch compatibility/precedence constraints, and keeps the maximum order spread under control. To demonstrate its effectiveness and efficiency, a computational study was set up, solving 920 test problems derived from the literature. The study enabled a proper tuning of the method and offered encouraging results: in 228 cases an optimum was found; in nearly all, the gap from the optimum was below 1%. Computation times range from fractions of seconds to a couple of minutes in the worst cases. Compared to existing methods, the algorithm provides on average the same solution quality, with the advantage of solving a problem which is more general and hence closer to application. The paper includes a discussion on the method extensions required to deal with asynchronous stacking and heterogeneous batches. 相似文献

Public activity in the telecommunications industry has experienced important transformations in the last decade: “reinvolvement” in infrastructure deployment, “innovative” boosting measures, and decentralisation of some decisions. Conceptually, even more important than the measures themselves is the fact that private agents often participate in their realisation and execution. This paper reviews how justifications for public action that would apply to any economic activity area have modelled the public-private relationship in the telecommunications sector. Subsequently, it focuses on the analysis of the new spaces for public-private collaboration that are currently opening up. 相似文献

We analyze the effects of neutral and investment‐specific technology shocks on hours and output. Long cycles in hours are removed in a variety of ways. Hours robustly fall in response to neutral shocks and robustly increase in response to investment‐specific shocks. The percentage of the variance of hours (output) explained by neutral shocks is small (large); the opposite is true for investment‐specific shocks. ‘News shocks’ are uncorrelated with the estimated technology shocks.
