Grid computing has recently become an important paradigm for managing computationally demanding applications, composed of a collection services. The dynamic discovery services, and the selection particular service instance providing be
In this paper we present and discuss a simple financial accelerator agent-based model, whose conceptual core is the interaction of heterogeneous firms banking system. Its simplicity notwithstanding, model able to replicate through simulations large number stylized facts concerning shape evolution over time distribution firms' sizes, growth rates, profits, “bad debt.”
We model an agent-based economy in which heterogeneous agents (firms and a bank) interact the financial markets. The heterogeneity is due to balance sheet conditions size. In our simulations, at aggregate level, output displays changes trend volatility giving rise complex dynamics. average solvency liquidity ratios peak during recessions as empirical analysis shows. At firm level generates: (i) sizes left-skewed distributed, (ii) growth rates Laplace distributed. Furthermore, small...
Power law behavior is an emerging property of many economic models. In this paper we emphasize the fact that power distributions are persistent but not time invariant. fact, scale and shape firms' size distribution fluctuate over time. particular, on a log–log space, both intercept slope change cycle: during expansions (recessions) straight line representing shifts up becomes less steep (steeper). We show empirical generated by simulations model presented in Ref. 11 mimic real remarkably well.
In macroeconomic models with financial constraints (see, for instance, Greenwald and Stiglitz, 1993; Bernanke, Gertler Gilchrist,1998; Kiyotaki Moore,1997) firms' supply decisions depend upon the degree of robustness/fragility, which is identifed measured in different ways. theoretical framework put forward by Stiglitz (GS hereafter), example, fragility due to presence bankruptcy risk. GS implicitly assume, however, that number firms constant. this paper we abandon one-to-one replacement...
In this article we perform an empirical investigation to detect whether and what extent agents' behaviour departs from those foreseen by the orthodox economic theory in Pescara wholesale fish market, which has a centralized structure. Using non-parametric techniques tools statistical physics, tackle issue investigating features such as dynamics of structure attendance auctions, varieties presentation during seller's turn presence long-term relationships between buyers sellers. We follow way...
The paper develops an agent-based model populated by heterogeneous consumers, a production sector and banking sector.Taking bottom up approach, the aims at providing first tool to analyze households' borrowing dynamics in di erent phases of business cycle relaxing some assumptions mainstream consumption models considering more realistic household behaviors.Although very simple, allows us grasp main implications interaction between consumers' wants (desired consumption), beliefs (their...
The present work provides an open-source, agent-based behavioral model primarily addressed to the dynamics associated with commodities spot price formation, as well variations and contrast patterns belonging exchanged quantity. framework can flexibly be used for several commodities, but it has integrated qualified modelization of producers’ buyers’ behavior when analysis a specific commodity, stock, or group merchandise. Due fact that various consumer artifacts are perceived treated...
The practice of detecting power laws and scaling behaviors in economics finance has gained momentum the last few years, due to increased use concepts methods first developed statistical physics. Some disappointment emerged economic profession, however, as regards models proposed so far theoretically explain these phenomena. In this paper we aim address criticism, showing that can naturally emerge a multiagent system with optimizing interacting units characterized by financial fragility.
Standard macroeconomics, based on a reductionist approach centered the representative agent, is badly equipped to explain empirical evidence where heterogeneity and industrial dynamics are rule. In this paper we show that simple agent-based model of heterogeneous financially fragile agents able replicate large number scaling type stylized facts with remarkable degree statistical precision.
