Vector‐borne diseases (VBDs) are widespread in less developed countries and reemerging in developed ones. Available economic studies agree that VBDs have significant effects on countries' economic outcomes, and affirm that a systematic evaluation of such effects is crucial for the efficient allocation of resources to health‐related priorities. This paper provides a comparative assessment of available methodologies for measuring the economic impact of VBDs at national level. We review both macroeconometric and micro‐based approaches, and examine advantages and disadvantages of current methods. We conclude by suggesting possible areas for future research. 相似文献

This article assesses the impact of trade, capital openness and institutions on emerging economies’ output loss during the “Great Recession.” The fixed-effect estimates of an unbalanced panel of 122 emerging countries observed from 2008 to 2010 yield three main results. First, trade openness has exacerbated output loss. Second, capital openness can help mitigate the negative impact of an external shock, but this is conditional on the level of financial development. Finally, the results also point out that the interrelations between financial and institutional development affect the crisis’s severity. 相似文献

This study finds strong empirical evidence in favour of the hypothesis that the age composition of population matters for labour productivity growth. We applied the fixed effects panel model using data on a large number of countries over the period 1980–2010. Our results suggest that higher age dependency not only directly impacts negatively on labour productivity but also modifies the impact of other determinants of labour productivity. Child dependency has a more adverse effect on labour productivity than old age dependency. We specifically find that the marginal effects of gross capital formation, information and communication improvement, and labour market reforms are significant at lower levels of age dependency. However, the marginal effect of savings on labour productivity is high at a high level of age dependency. The impact of age dependency varies between developed and developing economies. Diversity in the size and nature of age dependency across regions and different income groups help to explain the labour productivity differential across them. 相似文献

Performance evaluation of production systems monitored by statistical process control and off-line inspections 总被引:1,自引:1,他引:0
Quality and productivity performance measures are very often considered in separate phases of the production system design process. However, the production system architecture affects the efficiency of the quality control system as well as the quality control configuration has an impact on the performance of the production system.The paper proposes a new analytical method for evaluating the performance of production systems in which statistical process control (SPC) techniques are implemented. Machines behaviour is monitored by measuring quality characteristics of the produced parts through off-line inspection devices and sampling inspections. The numerical results show the good accuracy of the proposed method, provide new insight in the relations among the two areas and pave the way to the joint design of production logistics and quality control systems. 相似文献

Thanks to the access to labeled orders on the CAC 40 index future provided by Euronext, we are able to quantify market participants contributions to the volatility in the diffusive limit. To achieve this result, we leverage the branching properties of Hawkes point processes. We find that fast intermediaries (e.g. market maker type agents) have a smaller footprint on the volatility than slower, directional agents. The branching structure of Hawkes processes allows us to examine also the degree of endogeneity of each agent behavior, and we find that high-frequency traders are more endogenously driven than other types of agents. 相似文献

CAT bonds are of significant importance in the field of alternative risk transfer. Because the market of CAT bonds is not complete, the application of an appropriate pricing model is of high relevance. We apply different premium calculation models to compare them with regard to their predictive power. Without taking the financial crisis into account, a version of the Wang transformation model and the linear model are the most accurate ones. In contrast, under consideration of the financial crisis, all analyzed models are approximately equivalent. Furthermore, we find that CAT bond specific information does not improve out‐of‐sample results. 相似文献

In this paper, we analyze the problem of public debt-to-GDP stability in the Eurozone. We suggest that a feasible solution might be the realization of a market-financed, growth-enhancing investment program, which would be particularly welcome because of the positive short- and long-term repercussions it would have on GDP growth and the stabilizing effects on interest rates. Some simulations allow us to quantify these effects. The consequences of the COVID-19 pandemic further reinforce our policy implications in terms of public debt sustainability. 相似文献

There exist more than a dozen MS/PC-DOS programs with the capability of performing some form of survival analysis. Most of these are reviewed here, with respect to (1) the survival analysis methods they cover, (2) their ease of use and flexibility, (3) their user interface, (4) their graphics capabilities, and (5) their computational accuracy. 相似文献
