ABSTRACT

This paper accounts for the development of the academic endeavour to determine the firm-level relationship between investments in R&D and productivity. The impact of 28 highly cited publications within this line of study is investigated using a combination of bibliometric techniques and citation function analysis. We show how the attention paid to this line of research broadens and deepens in parallel to the diffusion of innovation as a research theme during 2000s. Our findings also suggest that the attraction of scholarly attention is driven by combination of broadening interest in the central research question under study and boundary-pushing methodological contributions made in the key contributions.  相似文献

The purpose of this paper is to investigate the relationship between private R&D, public innovation support transferred to the private sector, and productivity in Danish manufacturing. Two main conclusions are established. First, public innovation support has a positive and significant effect on private R&D expenditures with an estimated elasticity of 0.062. Second, the indirect effect on productivity from public innovation support is reflected in a positive point estimate which is found to be robust to different specifications of R&D capital.  相似文献

This paper provides a review and evaluation of different food‐risk prioritization and management frameworks that have been developed by governmental food‐safety authorities, regulatory agencies and non‐governmental institutions worldwide. It emphasizes the need for a new science‐ and risk‐based system approach to microbial risk prioritization. We find that most studies and projects argue for a systematic and multi‐disciplinary approach to risk prioritization but nevertheless lack it. Human and public health issues have constituted the core focus of food‐risk analysis in food‐borne risk prioritization studies, where the majority of studies use the concept of disease burden. Even though it is widely recognized that economic and market‐level impacts of microbial hazards and preventive interventions to reduce food‐borne risks are crucial to the performance of industries and markets, they are almost never accounted for in risk prioritization frameworks.  相似文献

This paper presents an ethnographic study of the travel culture of international backpackers. Their sociodemographic characteristics are described, the contours of a concept of tourism culture are delineated, and on that basis, that of backpackers is outlined, with particular focus on the key phenomenon of road status. The analysis of backpacker tourism as a culture furthers the comprehension of change within the phenomenon. Examples of factors of change include the guidebooks, the short-term backpackers, and in particular the internet. This study demonstrates the merit of a dynamic concept of culture where culture takes place whenever activated by social circumstances.  相似文献

This paper uses register data on tax assessed income from 1951 to 1989 for a representative sample of Swedish men in order to compare the distributions of annual income and "lifetime" income. It is found that the dispersion of lifetime income is around 35 to 40 percent lower than typical cross-sections of annual income. It is income up to around 30 years of age that mainly explains this discrepancy in the magnitude of dispersions. From the age of 30 until 65 years the correlations between annual and lifetime income are quite high and the dispersion of annual income is not very much higher than the dispersion of lifetime income. An analysis of the evolution of income mobility shows that there is a slight tendency to rising mobility over time. This finding implies that the common approach to study the development of income distribution by using only annual income can be misleading.  相似文献

Banks hold capital to guard against unexpected surges in losses and long freezes in financial markets. The minimum level of capital is set by banking regulators as a function of the banks’ own estimates of their risk exposures. As a result, a great challenge for both banks and regulators is to validate internal risk models. We show that a large fraction of US and international banks uses contaminated data when testing their models. In particular, most banks validate their market risk model using profit-and-loss (P/L) data that include fees and commissions and intraday trading revenues. This practice is inconsistent with the definition of the employed market risk measure. Using both bank data and simulations, we find that data contamination has dramatic implications for model validation and can lead to the acceptance of misspecified risk models. Moreover, our estimates suggest that the use of contaminated data can significantly reduce (market-risk induced) regulatory capital.  相似文献

During Sweden’s nineteenth-century modernization, Enskilda banks contributed to economic expansion and integration by providing generally accepted means of payment beyond what would have been possible for the central bank, the Riksbank. The Riksbank was constrained by specie-convertibility requirements for Sweden’s currency. Contrary to previous arguments, however, the Enskilda banks did not operate according to free banking theory. The Enskilda banks held Riksbank notes instead of specie as base-money reserves. This arrangement led to a higher supply of formal liquidity than what would have been the case with either a free banking system or a pure deposit-based commercial banking system. The consequence for Sweden was a rapid rate of monetization and financial deepening.  相似文献

There has been relatively little investigation of the effect of constitutional transformations on the economic transition in post‐communist countries. We develop a simple signalling model in which constitutionalism – a commitment to limit political power and provide judicial defence of basic rights – reinforces the credibility of pro‐market candidates’ electoral promises and boosts public support for economic reforms. These findings are tested using opinion poll data on public support for reform in Central and Eastern Europe, and in the former Soviet Union, in the 1990s. In a two‐stage procedure we show that public support for market reforms is higher in countries where incumbents have taken deliberate steps to increase political accountability and judicial independence. Public support also spurs actual economic reform.  相似文献
