Determination of disproportionate tenders in public procurement
2013
[EN] Public procurement is one of the fundamental pillars of the construction sector and the understanding of its statutory regulation is one of the keys to success. The government regulates the concept of disproportionate tenders to avoid deals that are too low, something which could jeopardise the execution of the work or cause problems during implementation such as conflicting prices, project modifications and delays. The criteria for determining the disproportionality of the offers are numerous and each contracting authority determines which to use in each process by carrying out a comparative analysis. The results show that the formulas of disproportionality based on a percentage of th…
Monte Carlo simulations of a trader-based market model
2002
Abstract We present a detailed analysis of the stationary state and the parameter sensitivity of a trader-based market model suggested in Bak et al. (Physica A 246 (1997) 430). The model in question takes only so-called noise-traders into account and its properties are determined by mutual imitation of the traders and volatility feedback. We show that the stationary state of the model can be characterized by a log-normal distribution of the bid and ask prices relative to the current market price. In the stationary state the model is able to reproduce the so-called stylized facts of real markets. This property is stable under variation of the essential parameters of the model, number of trad…
