Economic performance under different monetary policy frameworks

We examine the economic performance (inflation and growth) associated with different monetary policy frameworks, presenting unconditional and conditional analyses, and using predictions of countries’ monetary policy framework choices to address the issue of endogeneity. We find some differences in performance associated with the different monetary policy frameworks, together with a general improvement over time which is explained in part by the trends towards inflation targeting and more precise monetary control, that is from changes in the choice of framework, but in part, and perhaps more strongly, reflects a more general trend towards better economic performance related to changes in decision-making within the frameworks. Our results suggest that the choice of MPF is an important, but by no means the only, determinant of economic performance, and therefore not the only consideration for policymakers looking to improve economic performance.     

Towards more resilient economies: The role of well-functioning economic structures

Resilience is essential to better withstand adverse shocks and reduce the economic costs associated with them. We link resilience to the quality of countries’ economic structures. The paper finds robust evidence that sound labour and product markets and conditions for doing business increase the resilience towards adverse shocks and reduce the incidence of crises more generally. In the presence of a common shock, a country with weak economic structures can on average suffer up to twice the output loss in a given year compared to a more adaptable economy. From a policy perspective, this implies the need to push forward structural policies in countries with lower quality economic structures to increase resilience in case of future shocks. We also suggest how a monitoring process towards more resilient economic structures could look like.     

Stemming the downturn: How ambidexterity and public policy influence firm performance stability during economic crises

A key question confronting policy makers during economic crises is how they can support firms to maintain their performance levels until the economic storm has passed. The present study bridges insights from the ambidexterity and public policy literatures to examine how firm-internal responses (that is, ambidexterity) and external public policy incentives (that is, demand-pull policies) affect the stability of firms’ performance in a recessionary economic context. Using data from private German renewable energy firms at a time following the global financial crisis, we find that only firms with low ambidexterity achieve performance stability in light of demand-pull policies. This research draws attention to the relevance of stability as a policy-relevant performance measure during times of economic crises. Further, we suggest that greater insight into the interplay of managerial and political factors is necessary to enable policy makers to support the stability of certain industries during crises.     

Expanding the repertoire of evaluation tools so that evaluation recommendations can assist nonprofits to enhance strategic planning and design of program operations

Data are the lifeblood of decision-making and provide a critical component into the complex mosaic from which decisions emerge. Evaluators and decision-makers should, therefore, continuously seek to explore the use of tools that can produce more meaningful, insightful, and useful data so that decision-making can be enhanced and improved. Traditional economic appraisal methods offer much and are very useful and relevant. Standard financial accounting reporting for tax purposes also provide insightful information on the organization’s financial health and that of its individual programs. However, neither offer insight into cost behavior—an important consideration for making program operations more efficient and for long-term strategic planning, forecasting, and design of program operations. Before COVID-19, programs were already challenged with competition for donor dollars and the pursuit for financial sustainability. The COVID-19 environment has considerably exacerbated these challenges. In this current environment, it is more important than ever for nonprofits to optimize limited financial resources to do more societal good. This paper will illustrate how selected concepts from cost and management accounting can be used by both independent program evaluators to improve their recommendations, as well as program administrators in-charge of nonprofits to enhance decision-making.     

中国与“一带一路”六大经济走廊基础设施的双边贸易成本效应研究

在测算中国与“一带一路”六大经济走廊沿线国家双边贸易成本的基础上,基于引力方程和广义矩估计法,分析基础设施及其交互作用对双边贸易成本的影响。研究表明,随着时间推移,中国与六大经济走廊沿线国家的平均双边贸易成本虽然波折起伏,且与各经济走廊沿线国家的平均双边贸易成本的水平、下降幅度存在较大差异,但整体呈下降趋势。在控制人均收入差额、距离、贸易开放度、是否签署自由贸易协定、两国是否有共同边界等显著性影响因素后,研究发现,海运基础设施、陆空运基础设施以及二者的交互作用均能显著降低双边贸易成本,其中海运基础设施和陆空运基础设施交互作用的双边贸易成本效应较基础设施本身的双边贸易成本效应要低。     

Economic design of quick switching sampling system for assuring Weibull distributed mean life

In this paper, we propose the quick switching sampling system for assuring mean life of a product under time truncated life test where the lifetime of the product follows the Weibull distribution and the mean life is considered as the quality of the product. The optimal parameters of the proposed system are determined using two points on the operating characteristic curve approach for various combinations of consumer's risk and ratio of true mean life time and specified life time. Tables are constructed to determine the optimal parameters for specified acceptable quality level and limiting quality level along with the corresponding probabilities of acceptance. The proposed system is compared with other existing sampling plans under Weibull lifetime model. In addition, an economical design of the proposed system is also discussed.     

Vendor managed inventory in tramp shipping

This paper introduces a new problem to the OR community that combines traditional tramp shipping with a vendor managed inventory (VMI) service. Such a service may replace the more traditional contract of affreightment (COA) which for decades has been the standard agreement between a tramp shipping company and a charterer. We present a mathematical formulation describing the routing and scheduling problem faced by a tramp shipping company that offers a VMI service to its customers. The problem is formulated as an arc-flow model, and is then reformulated as a path-flow model which is solved using a hybrid approach that combines branch-and-price with a priori path-generation. To solve larger, and more realistic, instances we present a heuristic path-generation algorithm. Computational experiments show that the heuristic approach is much faster than the exact method, with insignificant reductions in solution quality. Further, we investigate the economic impact of introducing a VMI service, by comparing the results obtained with the new model with results obtained by solving the traditional routing and scheduling problem faced by tramp shipping companies using COA. The computational results show that it is possible to substantially increase supply chain profit and efficiency by replacing the traditional COAs with VMI services.     

Explaining the Muslim employment gap in Western Europe: Individual-level effects and ethno-religious penalties

It is well-documented that Muslims experience economic disadvantages in Western European labor markets. However, few studies comprehensively test individual-level explanations for the Muslim employment gap. Using data from the European Social Survey, this research note briefly examines the role of individual-level differences between Muslims and non-Muslims in mediating employment differences. Results reveal that human capital, migration background, religiosity, cultural values, and perceptions of discrimination jointly account for about 40% of the employment variance between Muslims and non-Muslims. Model specifications for first- and second-generation Muslim immigrants reveal a similar pattern, with migration background and perceived discrimination being of key relevance in mediating employment difference. While individual-level effects are indeed relevant, unexplained variance suggests that symbolic boundaries against Islam may still translate into tangible ethno-religious penalties.     

Economic design of non parametric sign control chart

An economic design of sign chart to control the median is proposed. Since the sign chart is distribution free, it can easily be applied to any process without prior knowledge of process quality distribution. The effect on loss cost observed for different shifts in location shows that the sign chart performs better for large shifts. The economic statistical performance study reveals that statistical performance of sign chart can be improved sufficiently for moderate shifts in the process. Sensitivity study shows that design is more sensitive for change in values of penalty loss cost and time required for search and repair of an assignable cause.
