The housing prices in many Asian cities have grown rapidly since mid-2000s, leading to many reports of bubbles. However, such reports remain controversial as there is no widely accepted definition for a housing bubble. Previous studies have focused on indices, or assumed that home prices are lognomally distributed. Recently, Ohnishi et al. showed that the tail-end of the distribution of (Japan/...

Asset price bubbles are considered to be a major risk to fi nancial stability. In this article, we show that an asset price bubble poses a bigger risk when banks are exposed to it. This is because when the bubble bursts, banks realise losses and this may trigger bank failures and a credit crunch. In contrast, when overvalued assets are held by ordinary savers, the consequences for fi nancial st...

A model which explains national-level house price appreciation through utility maximization by rational voters is developed and tested using a global sample of 40 democracies, in order to explain why some countries experienced house price bubbles in the past decade and others did not. In the model, a subsidy funded by a tax on all citizens can be provided to home buyers. The subsidy leads to an...

Food price bubbles are a phenomenon in which the cost of some food items or commodities climbs quickly and unreasonably before collapsing due to reasons such as speculation, supply demand imbalances, meteorological occurrences, governmental actions. Governments academics keep an eye on prices spot address these bubbles. The aim this paper is analyze bubble despite global slowdown by examining i...

in this research, the effect of bubble surface area flux, sb, and particle size on flotation rate constant, k, of pyrite (fes2) particles was studied using bubble-particle interactions. the bubble-particle collision, attachment and detachment efficiencies were calculated under different flow regimes. the k increased with increase in the collision efficiency and decrease in the detachment effici...

A weighted replicator dynamic describes how agents switch between a forecast based on fundamentals, a rational bubble forecast and a re‡ective forecast, a weighted average of the former two. If the innovations to the extraneous martingale have a similar magnitude to those of the dividend process and agents are su¢ ciently aggressive in switching forecasting strategies, a signi…cant portion of t...

In this article we are interested in option pricing in markets with bubbles. A bubble is defined to be a price process which, when discounted, is a local martingale under the risk-neutral measure but not a martingale. We do not require the underlying process to be continuous, so that Levy-based asset prices are also possible. We give examples of bubbles both where volatility increases with the ...

Recently housing price hikes are spreading across America spatially, a reminder of the stock market hikes of the 1990s that ruptured in 2000. The aim of this study were to identify the determinants of housing prices, the differences between housing and stock markets, and whether the housing market can follow the path of the stock market. The aim was also to examine the existence of a housing bu...

This paper examines how an asset price is determined in a market, and how it changes as circumstances in the market change, making use of a standard asset price model. The motivation of the paper is to examine if the model can explain a bubble economy in which individuals are risk averse. It is known that if the relative risk aversion of an investor’s utility function does not exceed 1 and is n...
