Application and research on the complex dynamics behaviour under price-discount promotion policy in inventory control system

In this paper, we study the inventory control system of the apparel industry supply chain in which the products are fast-fashion and mass-consuming goods. Retailers tend to promote by price-discount policy to regulate overstock situation caused by fluctuated demand, frequent product upgrading, etc. Here, we discuss the impact of fluctuated demand triggered by price-discount promotion policy on the comprehensive inventory control system in which the final inventory and supply line stock are considered and weighted differently according to corresponding practical operation situations. In this model, stock returns are permissible. Then we calculated the Lyapunov stable region of the decision parameters based on the state space model. These conclusions present the managers a big picture to inspect the inventory control system and serve as reliable references to make correct decisions.

需求价格弹性和销售收入关系的数学探析

文章认为,许多经济学教材中关于需求价格弹性对销售收入影响的结论存在明显缺陷,通过严格的数学分析,无论如何都不能得出需求价格弹性大于1时,降价会使销售收入增加这样的结论。正确的结论应该是:对同一条需求曲线,对应不同的点有不同的弹性,中点的价格弹性为1,是销售收入最大点,销售收入的变化由销售点在需求曲线上的位置及移动方向共同决定。     

The impacts of competition and shadow banking on profitability: Evidence from the Chinese banking industry

This paper contributes to the empirical literature on banking profitability by testing the impacts of competition and shadow banking on bank profitability using a sample of 100 Chinese commercial banks over 2003–2013 with 417 and 395 observations. The current study fills the gaps in the empirical studies by examining the competition in different banking markets (i.e. deposit market, loan market and non-interest income market) in China and further evaluating their impacts on bank profitability. The findings show that the non-interest income market has a higher level of competition compared to the deposit market and loan market. It is further reported that a lower level of competition in deposit market leads to an increase in the profitability of Chinese commercial banks. Finally, the results suggest that shadow banking improves the profitability of Chinese banks.

Small system dynamics model for alleviating the general practitioners rural care gap in Ontario,Canada

The disproportionate concentration of healthcare professionals in urban areas is a concern in many countries, including Canada. A need to address this rural care gap has driven a large number of government led initiatives worldwide over the years. This paper presents a model that can be used as a tool to examine the efficacy of such policies on the workforce distribution in the long term. A small system dynamics model is employed to simulate the current and future distribution of general physicians at a jurisdictional level. The model represents the transition of general practitioners to provide insight into the dynamics of care provision over time. The movement, and competition, between rural and urban areas is modeled to enable detailed exploration of the ability for proposed measures to alleviate the care gap in the future. Among the tested policies are such commonly used initiatives as financial incentives to rural professionals, promotion of medical education in rural areas, expansion of rural education programs and the engagement of international medical graduates etc. We demonstrate how the model can be used as a tool to determine an efficient and well-chosen combination of policies which can help alleviate the rural care gap in the future, given that some policies are more effective than others alone but also combined with other initiatives. The presented small system dynamics model is tested on Canada's reality, but its simple nature lends itself to easy application to other countries that experience a similar problem.

Explaining vaccination decisions: A system dynamics model of the interaction between epidemiological and behavioural factors

The WHO goal of eradicating measles is delayed by widespread scepticism of parents against the recommended MMR vaccination. In this context, a model of the prevalence of measles that incorporates behavioural aspects is desirable. Parental decisions can be influenced by epidemiological and behavioural factors. The former include vaccination coverage and its impact on the prevalence of the disease. The latter include perceptions of the risk to be infected, which affects vaccination decisions, as well as government campaigns to affect vaccination behaviour, vaccination scares or changes in disease control policies. We develop a model that incorporates both kinds of effects. In particular, we illustrate how incorporating parental response to a change in the prevalence of the disease impacts the outcome of governmental policies aiming to increase the vaccination coverage. While calibrated to measles, this model is also applicable to other childhood diseases, such as pertussis or diphtheria. Different scenarios illustrate the long-term consequences of the interaction between health policies (in particular, vaccination campaigns) or the agenda of social institutions (e.g., drawing attention to specific events to create vaccination scares) and parental reactions. Periodic ups and downs of the disease's prevalence, characteristic of epidemiological feedback, are the consequence of the interaction between parental behaviour and events such as vaccination campaigns or vaccination scares. International and national health authorities, pursuing the fight against measles, may be helped by the potential of the model to provide understanding in the way different predictors of vaccination behaviour interact.

Evolutionary game analysis and regulatory strategies for online group-buying based on system dynamics

The emergence of online group-buying provides a new consumption pattern for consumers in e-commerce era. However, many consumers realize that their own interests sometimes can’t be guaranteed in the group-buying market due to the lack of being regulated. This paper aims to develop effective regulation strategies for online group-buying market. To the best of our knowledge, most existing studies assume that three parties in online group-buying market, i.e. the retailer, the group-buying platform and the consumer, are perfectly rational. To better understand the decision process, in this paper, we incorporate the concept of bounded rationality into consideration. Firstly, a three-parties evolutionary game model is established to study each player’s game strategy based on bounded rationality. Secondly, the game model is simulated as a whole by adopting system dynamics to analyze its stability. Finally, theoretical analysis and extensive computational experiments are conducted to obtain the managerial insights and regulation strategies for online group-buying market. Our results clearly demonstrate that a suitable bonus-penalty measure can promote the healthy development of online group-buying market.     

Fuzzy model estimation of the risk factors impact on the target of promotion of the software product

ABSTRACT

This article studies the application of fuzzy logic to the risk analysis of a new software product development and marketing in specific case of a small size IT company. Identification and analysis of external and internal risk factors show that this type of business activity could be evaluated as high-risk enterprise. So, the purpose of the paper is to develop robust method to evaluate probability of occurrence of major risk events and their impact on the company financial health. The fuzzy logic is used to estimate degrees of threat of each relevant risk factor due to lack of reliable statistical data. The novelty of proposed approach is the inclusion into the model the risk event time.

一种车辆重载运输社会经济影响的评估方法

基于系统动力学(System Dynamics)理论建立公路货运系统的系统动力学模型,通过仿真分析车辆载重程度对货运需求、车辆使用决策、车型演化、车辆运输成本以及路面性能的长期动态作用,继而进行车辆重载运输的社会经济影响评估。最后形成一套完整的公路货运车辆重载运输对社会经济影响的系统化研究方法。基于实例的仿真结果表明,在货运车辆普遍重载的条件下,生产要素价格的变动、路面厚度的提高、路面维修间隔期的改变和公路税费标准的调整均不会对车流轴载水平乃至公路货运系统的运行产生根本性影响。在实施车辆载重限制后,系统行为又表现出以下重要特征:反直观性、远期与近期利益相矛盾、系统绩效受车辆载重标准与产业结构的影响较大。     

Interactive effects of brand reputation and ESG on green bond issues: A sustainable development perspective

This paper shows that brand reputation alone may not be sufficient to help firms successfully issue green bonds and that they may need superior corporate social responsibility performance in the form of high ESG (Environmental, Social, and Governance) scores to unlock the full potential of their brand reputation. Using a sample of 338 international green bond issues across 108 unique firms, we found significant positive effects of ESG disclosure score and its interaction brand reputation on the issuance of green bonds while controlling for other variables, such as fixed effects of industry, region, and time. We also show that it is the S (Social) component of ESG and the interactions of its E (Environmental) and G (Governance) components with brand reputation which drive successful green bond issuance. Besides extending the current research on the impact of brand reputation and ESG on green bonds, these results also have important managerial implications for analysts, fund managers, and firms planning to raise green capital.
