The present research proposes a new generalisation of the logistic model aiming at technology diffusion forecasting. Regarding criticisms and failures reported in the literature to apply logistic function for long-term forecasting, in our work we focused on short-term accuracy of forecast. To formulate the model, based on mathematical approximation, at first the differential equation governing the diffusion process is found and then by solving the derived differential equation, the forecast function is obtained. In all steps, mathematical tools from numerical analysis are used. We compared the New Generalized Logistic Model with eight of the most renowned models in the literature. The model led to more accurate fits and forecasts than those obtained from other models we applied for comparison. 相似文献

In this paper, I formulate a simple North–South R&D‐based growth model where final goods firms in the North endogenously determine the range of international outsourcing of intermediate goods to the South. I show that a fall in the trade cost (through trade liberalization) of intermediate goods in the North: (i) reduces the wage of the North relative to that of the South; (ii) increases the outsourced variety of intermediate goods in the North; and (iii) stimulates Northern R&D activity and economic growth in both countries. By conducting welfare analysis, I also show that a decline in the trade cost of intermediate goods in the North improves welfare in the South more than in the North. 相似文献

The procurement of infrastructure projects via public–private partnerships (PPPs) is rising globally. PPPs are, however, often characterized by lengthy tendering periods, defined as the difference between contract notice and financial close. Tendering periods are important because they account for a significant proportion of overall project delivery time. Slow tendering deters bidders and thus reduces competition for contracts. We source data on 670 PPP projects in the United Kingdom and use a duration analysis model to empirically examine factors that impact tendering period duration. Our results reveal significant sectoral variation with projects in the health and housing sectors taking significantly longer to reach financial close. We also show that, after controlling for other factors, projects with higher capital values and projects that overlap with the timing of general elections are associated with significantly longer tendering periods. We further examine the impact of the competitive dialogue procurement method and find evidence that tendering periods have increased since 2006; the year competitive dialogue was introduced. We do, however, observe a significant reduction in the time between appointment of preferred bidder and financial close post-2006. This suggests that competitive dialogue is effective in reducing the scope for negotiations by preferred bidders holding quasi-monopoly advantages. 相似文献

We examine the educational production function and efficiency of public school districts in Illinois. Using non-parametric kernel methods, we find that most traditional schooling inputs are irrelevant in determining test scores (even in a very general setting). Property tax caps are the only relevant factor that is related to districts’ financial constraints and have predominantly negative associations with test scores. Therefore, insufficient resources may be partially responsible for the lack of growth in test scores. For most other relevant inputs, we find substantial heterogeneity in the returns, which helps reconcile some of the puzzling results in the literature. We further find that there exist inefficiencies in school districts. Moreover, the level of test scores, commonly used as a measure of school effectiveness, (while related) differs substantially from our efficiency scores, and standard parametric approaches drastically underestimate school efficiency. We discuss the policy implications of our results. 相似文献

In this article, the authors discuss the use of Federal Reserve Economic Data (FRED) statistics to teach the concept of price elasticity of demand in an introduction to economics course. By using real data in its computation, they argue that instructors can create a value-adding context for illustrating and applying a foundational concept in economics. Additionally, this pedagogical strategy contributes to developing an expected proficiency for economics majors related to “interpreting and manipulating data” (Hansen 2009, 2012). The authors provide step-by-step instructions on how to use FRED to compute the price elasticity of demand for motor vehicle fuels and gasoline as well as examples of in-class discussion questions and take-home assignments related to this instructional technique. 相似文献
