The paper aims to analyse the behaviour of a battery of non-survey techniques of constructing regional I-O tables in estimating impact. For this aim, a Monte Carlo simulation, based on the generation of ‘true’ multiregional I-O tables, was carried out. By aggregating multi-regional I-O tables, national I-O tables were obtained. From the latter, indirect regional tables were derived through the application of various regionalisation methods and the relevant multipliers were compared with the ‘true’ multipliers using a set of statistics. Three aspects of the behaviour of the methods have been analysed: performances to reproduce ‘true’ multipliers, variability of simulation error and direction of bias. The results have demonstrated that the Flegg et al. Location Quotient (FLQ) and its augmented version (AFLQ) represent an effective improvement of conventional techniques based on the use of location quotients in both reproducing ‘true’ multipliers and generating more stable simulation errors. In addition, the results have confirmed the existence of a tendency of the methods to over/underestimate impact. In the cases of the FLQ and the AFLQ, this tendency depends on the value of the parameter δ. 相似文献

Technological innovations are often designed to help consumers save time. However, some consumers refuse to use innovations and downgrade their usability with increasing usage time. The purpose of this research is to find out how consumers?? personality in younger (vs. older) men (vs. women) affects behavioral choices of the mobile Internet, as an example of new technology, and how usage time affects perceived ease of use of innovative (vs. established) media. The study shows that innovativeness, low desire for social contact, and technology optimism, in interaction with demographics, determine whether consumers choose mobile Internet services over substitutes. Job-related dependency on technology and gender directly affect choice behavior. The study reveals that ease of use is downgraded as more time is spent using the mobile Internet, whereas there is no such relation for established media. The results help explain overoptimistic forecasts that were made in the field of technology acceptance. 相似文献

The paper investigates the diversified patterns of outsourcing in the Lombardy region and relates them to the probability of introducing product and process innovation. Based on a large firm-level survey, we show that outsourcing processes are strongly regionally embedded and that offshoring is still a limited phenomenon. Outsourcing strategies are shown to be positively related to firms’ innovation. In particular, the outsourcing of service activities is mostly related to product innovation, thus suggesting that firms successfully pursue core strengthening strategies. Our econometric estimates show that both geographical and organisational proximity matter. Indeed, the positive association of services with innovation is strongly related to their regional dimension, which points towards the importance of local user–producer relationships. When outsourcing crosses national borders, keeping the outsourced activities within extended organisational boundaries (i.e. within the group or network of affiliates) appears relevant, particularly with reference to R&D activities. 相似文献

The paper applies a semi-parametric propensity score matchingapproach to evaluate the effects of agri-environment (AE) programmeson input use and farm output of individual farms in Germany.The analysis reveals a positive and significant treatment effectof AE programmes on the area under cultivation, in particulargrassland, resulting in a decrease of cattle livestock densities.Furthermore, participation significantly reduced the purchaseof farm chemicals (fertiliser, pesticide). We also find differencesin the treatment effect among individual farms (heterogeneoustreatment effects). Farms that can generate the largest benefitfrom the programme are most likely to participate. 相似文献

(1248) Andrea Goldstein, Nicolas Pinaud, Helmut Reisen and Dorothy McCormick When the OECD Development Centre launched research in 2005 to document the economic, political and social impacts of China’s and India’s economic growth on sub‐Saharan African (SSA) countries, the arrival (or resurgence) of new important players had triggered concerns among traditional donors. Accusations ran from free riding on Western debt relief over violation of governance standards and unfair company competition to fragmentation of aid delivery. At the same time, there was a tendency to neglect the diversity of SSA in terms of resource endowments, trade links and industrial development. It was time then to promote African voices from various backgrounds to reflect Africa’s heterogeneity. The introductory section presents a summary of findings about the economic impact of the two Asian giants in SSA countries by Africa‐based economists, with three practical conclusions. First, African countries should favour strategies that minimise areas of direct competition with the Asian giants. Second, industrialisation strategies are required to exploit opportunities complementary to the Asian development path. Third, sectors of mutual interest should be identified in order to develop long‐term views on how to cooperate with China and India and these views should be mainstreamed into national development plans. 相似文献

This work explores some distributional properties of aggregate output growth‐rate time series. We show that, in the majority of OECD countries, output growth‐rate distributions are well approximated by symmetric exponential power densities with tails much fatter than those of a Gaussian (but with finite moments of any order). Fat tails robustly emerge in output growth rates independently of: (i) the way we measure aggregate output; (ii) the family of densities employed in the estimation; (iii) the length of time lags used to compute growth rates. We also show that fat tails still characterize output growth‐rate distributions even after one washes away outliers, autocorrelation and heteroscedasticity.
