چکیده

In an asset-pricing model, risk-averse agents need to forecast the conditional variance of a stock’s return. A near-rational restricted perceptions equilibrium exists in which agents believe prices follow a random walk with a conditional variance that is self-fulfilling. When agents estimate risk in realtime, recurrent bubbles and crashes can arise. These effects are stronger when agents allow for ARCH in excess returns. JEL Classifications: G12; G14; D82; D83

When agents estimate risk in real-time, recurrent bubbles and crashes can arise. These effect are stronger when agents allow ...

Spatial analysis to identify high risk areas for traffic crashes resulting in death of pedestrians in Tehran

Background: More than 20% of deaths from traffic crashes are related to pedestrians. This figure in Tehran, the capital of Iran, reaches to 40%. This study aimed to determine the high-risk areas and spatially analyze the traffic crashes, causing death to pedestrians in Tehran.   Methods: Mapping was used to display the distribution of the crashes. Determining the distribution pattern of...

A mechanism leading bubbles to crashes: the case of Japan’s land markets

In this paper we investigate quantitatively statistical properties of ensemble of land prices in Japan in the period from 1981 to 2002, corresponding to the period of bubbles and crashes. We find that the tail of the distributions of ensembles of the land prices in the high price range is well described by a power law distribution, P (S > x) ∼ x−α, and furthermore that as the power-law exponent...

Fearless versus Fearful Speculative Financial Bubbles

Using a recently introduced rational expectation model of bubbles, based on the interplay between stochasticity and positive feedbacks of prices on returns and volatility, we develop a new methodology to test how this model classifies 9 time series that have been previously considered as bubbles ending in crashes. The model predicts the existence of two anomalous behaviors occurring simultaneou...
