  Citation × Citation Citation Abstract Copy Title: Advancing Rationality with Sustainability: An Analysis of Agent-Based Simulation Author: Tanrikulu, Osman Goktug Year: 2017 Today, falling trends of species and ecosystem in the world due to overconsumption and destruction of natural resources are at critical levels. It is vital for humanity to operate with sustainable and resilient modes of production and consumption. In this regard, this paper examines the basic premise of rationality and introduces sustainability as an advancement to the theoretical concept of rationality. Thus, a rational mindset and a sustainable mindset are compared under depletion of environmental resources. The understanding of rationality in the analysis is based on Garett Hardin’s (1968) ‘the tragedy of the commons’ model, in which actors are self-interested and individualistic while seeking resources. Conversely, a sustainable mindset acknowledges environmental limitations and takes action accordingly. By utilizing agent-based modeling, both rational and sustainable mindsets are modeled, and their relative behavior are put into action in computer simulation. The results reveal that the basic understanding of rationality is not always going to maximize the utility of agents. Instead, there may be environmental conditions where having a sustainable mindset generates more wealth. In a scenario of resource depletion, the chances of survival decrease for rational agents. Their situation is exacerbated if their level of greed increases. However, the sustainable agents continue making stable wealth even with limited environmental resources. Rational actors must develop a sustainable mindset in order to acclimatize themselves to environmental deterioration.

  Citation × Citation Citation Abstract Copy Title: A Systems Approach to Ecological Economic Models Developed Progressively in Three Interwoven Articles Author: Uehara, Takuro Year: 2012 My dissertation develops and analyzes ecological economic models to study the complex dynamics of an ecological economic system (EES) and investigate various conditions and measures which can sustain a developing economy over the long term in view of resilience and sustainability. Because of the intrinsic complexity of the system, I take a systems approach, using economics as the foundation for the basic structure of an ecological economic model, and system dynamics as the method to build and analyze such a complex ecological economic model. Throughout my dissertation, the model developed by Brander and Taylor (1998) is adopted as a baseline model (henceforth the BT model). The BT model explains population-resource dynamics and is characterized as a general equilibrium version of the Gordon-Schaefer Model, using a variation of the Lotka-Volterra predator-prey model. The findings are presented as three articles. The first article provides a comprehensive analysis of the BT model and its descendants, to elicit directions for further research, including population growth logic, substitutability, innovation, capital accumulation, property rights and institutional designs, and modeling approach. The second article extends the BT model to study the resilience of an EES reflecting three key issues in modeling such systems: 1) appropriate system boundary, 2) non-convexity of ecosystems, and 3) adaptation. The article discusses two types of thresholds: the ecological threshold, a threshold for an ecological system independent of economic systems, and the ecological economic threshold, a threshold for an EES. The latter is often different from the former and is highly dynamic and context dependent. The third article is another extension of the BT model to study the sustainability of an EES by implementing the suggestions made by the first article except for property rights and institutional designs. The main focus is on the impact of endogenous innovation regarding input substitutability on the system sustainability. The main finding is that improvement in the input substitutability, ceteris paribus, may not contribute to sustainable development despite its contribution to expanding the economy. However, it could be possible for susbstitutability improvements to contribute to sustainable development when combined with other specific types of technological progress.
