In this paper, a model of an ecosystem influenced by a large human population is presented. It is modelled by a discrete time dynamic game with many players and a simple dynamics. The paper proposes a new way to look at the problems of exploitation of ecosystems by many users — using the...

In this paper we develop an heterogenous agents model of asset price and inventory with a market maker who considers the excess demand of two groups of agents that employ the same trading rule (i.e. fundamentalists) with different beliefs on the fundamental value. The dynamics of our model is...

We propose a two-market heterogeneous agents model with coupling mechanism to study Financial crisis with contagion effect. It manages to calibrate sudden crash behavior of US and UK stock markets during "Black Monday" of 1987 besides smooth crisis and disturbing crisis categorized in...

The aim of this paper is to simulate profit expectations as an emergent property using an agent based model. The paper builds upon adaptive expectations, interactive expectations and small world networks, combining them into a single adaptive interactive profit expectations model (AIE)....

The hedge fund represents a unique investment opportunity for the institutional and private investors in the diffusion-type financial systems. The main objective of this condensed article is to research the hedge fund’s optimal investment portfolio strategies selection in the global capital...

Markov-switching rational expectations (MSRE) models can bring out fresh insights beyond what linear rational expectations models have done for macroeconomics, as noted and predicted by Davig and Leeper (2007) and Farmer, Waggoner and Zha (2009), among others. However, a lack of tractable...

This paper considers a discrete-time model of a financial market with one risky asset and one risk-free asset, where the asset price and wealth dynamics is determined by the interaction of two groups of agents, fundamentalists and trend extrapolators. In each period each group allocates its...

We examine the role of expectations in a model aimed to explain financial fluctuations. The model restates the core of Minsky’s financial instability hypothesis, focusing on the role of expectations. The hypotheses concerning the process of formation and revision of expectations are discussed...

With the development of globalization and regional market integration, regional markets with common currency emerge. We develop a heterogeneous agents model based on the frameworks of Day and Huang (1990) as well as Westerhoff and Dieci (2006). Two markets using same currency are populated by...

It is systemic to expound how that the speculative behaviors are driven by the number of a series housing policies promulgated by China's government for the real estate market. The market is resulted in full of speculative behaviors, and has been booming since the beginning of this decade, even...
