Why is this topic of house price indexes important? The Global Financial Crisis has several causes but a main cause was a housing bubble in the U.S. which led banks to make mortgage loans that were based on the assumption that house prices were not rising unusually quickly. If accurate regional house price indexes for the U.S. would have been widely available to the public, it is unlikely that ...

today one of the major questions in the iranian economy is that do liquidity injected into the economy more effected productive activities or speculative activities .this study was conducted to compare the effects of liquidity growth on real sector and assets market bubbles in iranian economy during the period 1994(2)-2012(1). for this purpose, price index of four major assets in iranian econom...

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...

Stock-based compensation puts managers in the position of having, at some point, to sell stock. The prevalence of stock-based compensation in the 1990s allegedly created incentives for managers to hype their companies’ stock price by manipulating earnings before selling stock. Consistent with this conjecture, we find that managers tended to inflate earnings prior to selling stock. Moreover, the...

Trading at prices above the fundamental value of an asset, i.e. a bubble, has been verified and replicated in laboratory asset markets for the past seven years. To date, only common group experience provides minimal conditions for common investor sentiment and trading at fundamental value. Rational expectations models do not predict the bubble and crash phenomena found in these experimental mar...

The rapid increase in home prices over the past several years has raised concerns about the existence of a speculative bubble in this asset market. A closely related concern—irrespective of any existing bubble—is whether home prices are susceptible to a steep decline that could have a severe impact on the broader economy. Indeed, home prices have been rising rapidly. Since 1995, real home price...

Data from the Jicamarca digisonde and the ROCSAT-1 satellite are employed to study the equatorial ionosphere on the west side of South America during April 1999–March 2000 for the concurrent bottomside spread F (BSSF) and plasma bubble events. This study, using digisonde and ROCSAT-1 concurrently, is the first attempt to investigate the equatorial spread F. Results show that BSSF and plasma bub...

We analyze the stock market by modeling it as a timing game among arbitrageurs for beating the gun. We assume that (1) arbitrageurs are behavioral with a small probability, (2) the bubble soft-lands, and (3) the postcrash price increases as the X-day is postponed. Due to these assumptions, the effect of reputation assumes importance because any rational arbitrageur is willing to build a reputat...
