为实现大规模集成电路中的"自动布线问题",首先针对单层平面内通道自动布线问题使用A*算法,发现上下引脚连接线路发生路径冲突时,单通道自动布线问题无解.对多层数电路通道自动布线使用Floyd算法建模,分别对每层线路进行优化.构建基于遗传算法的A*目标函数最优化自动布线模型,来解决三维空间结构优化、系统整体布线距离优化以及金属线与通孔寄生电阻最小化问题.之后使用样本测例对建立的模型进行验证,提出新的解决路线.  相似文献

We analyse real income convergence among the EU28 countries throughout 1995–2017 and the relationship with the convergence patterns of financial systems. We apply the nonlinear latent factor model of Phillips and Sul (2007, 2009) to real incomes and the IMF financial development indices for financial markets and financial institutions (Svirydzenka, 2016), and identify convergence clubs endogenously. We have several results. First, income disparities narrowed significantly over the last twenty years; yet, the growth convergence process lost momentum triggered by the global financial crisis and countries legacies shaped up asymmetries that have crystallised. Second, countries' financial systems exhibit high fragmentation, especially for financial markets, with the new EU member states at a lower financial development, confirming the existence of a two-tier Europe. Overall, the convergence patterns for real incomes and financial development are strongly correlated. Finally, the financial structure matters and market-oriented economies feature higher long-run growth, indicating the need to implement pan-European policy actions that increase the opportunities of risk diversification, enhance capital raising and channel large-scale financing to firms.  相似文献

We examine the co-movement of the G7 stock returns with the numbers of confirmed COVID-19 cases and causalities based on daily data from December 31, 2019 to November 13, 2020. We employ the wavelet coherence approach to measure the impact of the numbers of confirmed cases and deaths on the G7 stock markets. Our findings reveal that both the number of confirmed COVID-19 cases and the number of deaths exhibit strong coherence with the G7 equity markets, although we find heterogeneous results for the Canadian and Japanese equity markets, in which the numbers of COVID-19 cases and the deaths exhibit only a weak relationship. This evidence is more pronounced in the long-term horizon rather than the short-term horizon. Moreover, the lead-lag relationship entails a mix of lead-lag relations across different countries. We present the implications of these findings for both policymakers and the international investment community.  相似文献

There are various factors that determine and influence economic growth. From these, one of the most significant factors is exports, which play a vital role in the economic growth and development of a country. Trade theory states that exports enhance the growth of a domestic economy in various ways. This study attempts to empirically investigate the existence of the exports-led-growth (ELG) or growth-led-exports (GLE) hypotheses by adopting comparatively more contemporary techniques as compared to earlier classical approaches for China and Pakistan for the period of 1980 to 2015. The study found the existence of ELG for both China and Pakistan.  相似文献

ABSTRACT

This study aims to investigate the impact of competition on determinants of allocative, scope and cost efficiencies of Indian scheduled commercial banks (SCBs). Specifically, the study, analyzes the impact of the second round of licensing on the efficiency of Indian SCBs. This is the first paper to measure scope efficiency of Indian banks and analyze its determinants. A two-stage analysis is performed on a balanced panel dataset of Indian SCBs for the period 1999–2016. In the first stage, the allocative, cost and scope efficiencies for each bank are estimated following the data envelopment analysis approach. In the second stage, internal determinants of the stated efficiency measures are estimated following the system of the generalized method of moments approach. The findings suggest that competition has not resulted in enhancing the efficiency of Indian SCBs. Among factors that can influence efficiency, it is seen that size does matter. Larger banks can enhance the efficiency of SCBs. It is also seen that having more foreign banks improves the overall efficiency of SCBs. However, before embarking on further rounds of licensing, the study posits that market-driven correction to succeed, it is imperative to address sunspots in the form of investor or borrower repression.  相似文献

The authors propose a classroom experiment implementing a simple version of a New Keynesian model suitable for courses in intermediate macroeconomics and money and banking. Students play as either the central bank or members of the private sector. The central banker sets interest rates to meet twin objectives for inflation and the output gap or to meet only an inflation target. In both settings, private sector agents are concerned with correctly forecasting the inflation rate. The authors show that an experiment implementing this setup is feasible and yields results that enhance understanding of the New Keynesian model of monetary policy. They propose alternative versions where the central bank is replaced by a policy rule and provide suggestions for discussing the experimental results with students.  相似文献

A comparison study was undertaken between the asset-based community-led development (ABCD) approaches versus the traditional needs-based approach to community development relating to community leadership. A purposive sampling technique was used to select 24 community projects in South Africa for the study, of which 14 were sensitised to ABCD and 10 were not. The kind of community leadership developed in ABCD communities enabled communities to lead their own development by co-investing their own assets, and leveraging their assets with resources from external agencies. In comparison, although development took place, the leadership that emerged in the needs-oriented projects was more authoritarian in nature, and in some instances, seemed to establish a dependency on external agencies. Community leadership that contributes to projects that were more driven by community members complements the principles of appreciative leadership, which were more evident in ABCD-sensitised communities.  相似文献

This study explores the cost-reduction effects of local government consolidation, using data from Japanese municipalities. We use municipal panel data from Japan for the years 2000, 2005 and 2010, a data set including numerous consolidation cases. Reverse causality between consolidation decisions and size of municipal expenditure is a concern in the voluntary consolidation of local governments. An instrumental variable (IV) methodology is employed to deal with possible endogeneity associated with consolidation decisions. The main finding is that municipal current expenditure per capita increases immediately after consolidation, but then gradually declines. Because consolidation seems to increase per capita expenditure in the absence of the effect of this long-term declining trend, incorporating this trend into estimation is crucial in cost-efficiency analysis of consolidation. It is also shown that conventional panel data regressions yield biased consolidation effects, suggesting the superiority of the IV approach.  相似文献
