- Description:
- The technological developments of our time provide the basis for a continuous flow of new applications and services. But even when allowing for significant improvements in everyday life, some of these innovations need an incredibly long time to be broadly â if at all â accepted in the market. Marketing and technical implementation are often only partially responsible. Consumers additionally need to overcome personal barriers to adopt an innovation. The height of this barrier is determined by manifold aspects like: Financials, required infrastructure, technical affinity, expected learning efforts, and safety concerns. In this article we introduce a market diffusion model that explicitly takes individual adoption barriers into account, while maintaining the top down approach of Business Dynamics. The model includes a feedback loop between the number of existing adopters and the number of consumers prepared to adopt the innovation. It explicitly allows for the adoption by only a portion of the potential customers. Furthermore, the model can reproduce tipping points and visually explain slow market developments or unexpected late successes.

- Description:
- In this paper by means of a simple system dynamics model, we have addressed a cycle-producing mechanism in the owner-occupied real estate market which has not been discussed in the real estate economics literature before. This mechanism is based on accumulation of supply and demand which arises from specific stock-flow structure of a durable goods market like the owner-occupied market. Comparison between our model and a famous model of rental market (Wheaton, 1999) shows that despite the rental market, in the owner-occupied market an increase in durability of buildings leads to more intensive oscillations. Also the effect of price elasticity of supply on the cycles in the owner-occupied market is much more complex than that of the rental market. Furthermore a model integrating the two markets is developed. Model analysis reveals that the interrelations between the two markets make the effect of some parameters on the rental market cycles different from what is suggested by the rental market model. Our work uncovers the rich dynamic complexity of the real estate system and can serve as a good example of applying systems thinking principles to complex real world problems. Keywords: Real Estate Cycles; Owner Occupied Market; Durable Goods; Cycle-Producing Mechanism (CPM); Dynamic Complexity; System Dynamics Modeling.

- Description:
- In this paper, we describe a model of two judges acting in parallel. We expand work related to the identification of threats by analyzing the effectiveness of including a second judge in the process and identifying its effects on performance and error rates. In addition, we explore the implications for learning under uncertainty.

- Description:
- Despite the increasing frequency of cross-border mergers and acquisitions, it is accepted that the rate of success in the post-merger phase remains poor; the main reason for this is widely accepted to be the unsuccessful cultural integration of the two firms involved. Driven by limited time to obtain results, managers from the headquarters (of the acquiring firm) seek to change the culture of the subsidiary (of the acquired firm); the imperatives of a âstrong cultureâ lead them to persevere with the same narrow strategies and objectives. Though organizational culture has been widely studied in the M&A literature, there has been insufficient attention to important dynamic aspects of the process of integration. This paper, with the help of appropriate concepts of culture dynamics from anthropologists, formulates a description of the integration process. Subsequently, by simulating a mathematical model of this process (which explores the impact of two exogenous variables that characterize the context) we bring out the role of endogenous dynamics in determining the success of typical narrow strategies. Specifically, we explain how the nature and strength of the constituent feedback loops shape the non-uniform evolution of relevant constructs in the integration process. We conclude with implications for managers and researchers.

- Description:
- In the report many methodological and technological approaches for creating Decision Support Systems for regional and federal authorities are presented. They are based on using new information technologies such as Data Warehousing, On-Line Analytical Processing, simulation modeling and others. The general structure of model complex for region social-economic development and its realization based on methods of system dynamics and modern technologies of simulation modeling are described.

- Description:
- Many green practices are widely understood and known to bring benefits beyond reduced energy use. Yet, organizations often fail to implement them. What explains these failures? Past theory suggests that adoption and implementation will be most likely to fail when practices are difficult to recognize given current competencies or organizational structures, require complex knowledge, or when the organization faces short term pressures that force it to abandon implementation early. Here, we present a case study of an organization that fails to adopt an important best practice despite the fact that the benefits and steps toward implementation are well understood and external short term pressures are minimal. We find that instead, short term pressures are created entirely internally by the structure of relations across organizational boundaries, causing individuals to misperceive the best practice as a cost that can be put off rather than an investment with positive future returns. Thus, even the simplest of innovations and improvements can be stymied by dynamics internal to an organization.

- Description:
- Governments around the world have developed e-government programs hoping to obtain important benefits. However, many e-government projects fail to deliver their promises. Some of such failures are the result of a lack of understanding about the relationships among technologies, information use, organizational factors, institutional arrangements, and socio-economic contexts involved in the selection, implementation, and use of information and communication technologies (ICT), producing mismatches and unintended consequences. The paper proposes the use of institutional theory and dynamic simulation, particularly System Dynamics, as an integrated and comprehensive approach to understand e-government phenomena. The paper draws on the case of the e-Mexico program, particularly in the strategy to create web-based content to the citizen in the areas of education, health, economy and government. Using the same technological infrastructure and under the leadership of the same Federal Ministry, four different networks of government and non-government organizations engaged in the creation of Internet portals to create relevant content in these areas. Differences in institutional arrangements and organizational factors resulted on different technology enactments.

- Description:
- This paper presents a preliminary System Dynamics model developed to analyze sustainability of a natural reserve in Mexico: the Tamiahua wetlands. Wetlands are often referred to as natureâs kidney because they filter contaminants from water. In spite of their importance, wetlands are endangered areas around the world. The preliminary model presented in this paper suggests that fishing activity in the Tamiahua wetlands, together with contaminants from human activity, have the potential to damage the diversity of species in the ecosystem, endangering the sustainability of the system. Continued work on the model is intended to explore appropriate ways of preserving Tamiahua, providing inhabitants with economic activities that promote the sustainability of the region.
