A system dynamics model for the assessment of the effects of advertising and sales promotion on profitability

Advertising and sales promotion have significant impact on raising customer awareness. They are tools by which customers become acquainted with new and innovative products and services of the companies. Despite the importance of these tools in increasing sales, it is not easy to evaluate their effect on sales. One of the problems confronted by the marketing managers is the determination of a clear relationship between the effectiveness of advertising and sales promotion on profitability. In this article, considering the relationship between these tools and brand equity, we have attempted to determine the relationship between effectiveness of these two factors and profitability. Next, a system dynamics model for representing the effects of marketing communication tools on company profitability is offered. Finally, using the data from a corporation and the numeric values related to each of the elements in the model, an attempt has been made to determine a number representing the magnitude of the effect of advertising and sales promotion on the corporation＇s revenue and profitability and to draw the respective curves related to the effects of these two factors.

Conditions for policy implementation via co-production: the control of dengue fever in Brazil

In this paper, we identify the conditions that must be present for effective policy implementation using co-production. To this end, we investigated five cases in which co-production was used to combat the vector of dengue, the Aedes Aegypti mosquito, in Brazil. Data were analysed using content analysis and crisp-set QCA methods to identify the combination of conditions that explain successful outcomes. Five conditions were found to be necessary for effective implementation via co-production: technical, economic, normative, cognitive and structural. The contribution of this study is to provide empirical evidence with respect to the conditions that effectively lead to successful outcomes.     

An assessment of China's joint prevention and control policy on sulfur dioxide emissions reduction: A spatial econometric analysis

Sulfur dioxide (SO₂) is a typical pollutant that affects human health, climate, and environmental and ecological conditions. China has been experiencing high concentrations of SO₂, particularly in urban areas, since the 1990s. In 2010, a “joint prevention and control” (JPC) policy was issued to address air pollution problems and strengthen the regulation of SO₂ emissions. This study aimed to describe the mitigation effects of this policy on SO₂ emissions in 116 Chinese cities from 2003 to 2017. We applied global and local Moran's I indices to confirm the presence of significant spatial autocorrelation in SO₂ emissions and constructed four spatial models to assess the effect of the JPC policy in reducing SO₂ emissions and its transmission mechanism. We found that the policy decreased SO₂ emissions by 1.89 × 10⁴ tons, SO₂ intensity by 1.70 tons per km², and SO₂ per capita of 158.49 tons per 10,000 people in each city, on average, all of which are significant changes. The empirical results also show that population growth, economic structure, and environmental protection significantly decrease SO₂ emissions. Finally, we recommended policies to encourage regional cooperation under the JPC policy, with the aim of promoting further reductions in SO₂ emissions.

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.
