This paper provides an equilibrium framework to organize the following empirical observations in the U.S. housing market from 1975 to 2007: (i) housing tenure and vacancies were approximately constant, (ii) rents were approximately constant, and (iii) in the late 1990s there was a large house price appreciation. Borrowing ideas from search and matching theory, and closing the model with self-fu...

Theory predicts that the effects of search frictions on house prices from temporary movements in demand should be temporary, while the data suggests it is permanent. The latter implies that movements in demand coupled with search frictions create higher volatility in prices than theory would predict, amplifying price changes, leading to bubbles and depressions. To generate permanent price chang...

Given the financial and economic damage that can be caused by collapse of an asset price bubble, it is critical importance to rapidly detect onset a crash once bubble has been identified. We develop real-time monitoring procedure for detecting episode in time series. adopt autoregressive framework, with regimes modelled explosive stationary dynamics, respectively. The first stage our approach m...

This article studies whether there is a bubble in the price of medical masks, especially considering COVID-19 pandemic. The empirical results show that multiple bubbles exist 2020 and are correlated with related events. study alerts investors to rationally evaluate changes stock market during

We study and generalize in various ways the model of rational expectation (RE) bubbles introduced by Blanchard and Watson in the economic literature. Bubbles are argued to be the equivalent of Goldstone modes of the fundamental rational pricing equation, associated with the symmetry-breaking introduced by non-vanishing dividends. Generalizing bubbles in terms of multiplicative stochastic maps, ...

the presence of bubbles in the markets and its formation has been regarded by economists and they have been looking to develop methods that can be recognized by using appropriate method for the formation of bubbles. in this paper, first, the formation of bubbles is tested using the new unit root test known as phillips test (generalized sup adf test) for 50 companies in the tehran stock exchange...

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 decreas...

We estimate the dynamics of a speculative bubble subject to surviving and collapsing regime together with dividends returns in tractable state space specification present-value model. To this new high-dimensional model, we develop an efficient Markov chain Monte Carlo sampler simulate from joint posterior distribution. find that real-world stock price bubbles show significant Markov-switching s...

This study attempts to investigate the nexus between investor sentiment and cryptocurrencies prices. Our empirical investigation merges bivariate multivariate wavelet tools examine inter-cryptocurrencies The outcomes show that Sentix Investor Confidence index provides significant information in explaining long-term changes Bitcoin Litecoin Moreover, findings generated from multiple coherence il...
