Empirical evidence has demonstrated that there are bubbles in the prices of financial assets, in other words, when assets are traded at prices either above or below their fundamental value. With this in mind, it is desirable to seek answers to the following questions: What reasons are given by...

In this paper, we investigate short sale constraints' impact on the incidence of extreme stock market movements. The latter can be used to proxy for the likelihood of tail events like crashes and bubbles in a market and, thus, is a crucial measure of stock market stability. Since crashes and...

We show how the timing of financial innovation might have contributed to the mortgage bubble and then to the crash of 2007-2009. We show why tranching and leverage first raised asset prices and why CDS lowered them afterwards. This may seem puzzling, since it implies that creating a derivative...

Based on a method developed by Laybourne, Kim and Taylor (2007) for detecting multiple changes in persistence, we test for changes in persistence in the dividend-price ratio of the Nasdaq stocks. The results confirm the existence of the so-called Dotcom bubble around the last turn of the century...

Stocks of German renewable energy companies have commonly been regarded as lucrative investment opportunities. Their innovative line of business initially seemed to promise considerable future earnings. As shown by two powerful bubble tests, the positive sentiment for renewable energy stocks...

Recent discussions on the volatility of agricultural prices have been drawing on factors as low short term elasticities of supply and demand, climatic risk, market uncertainty, central banks monetary policies, trade barriers, biofuel development and, finally, speculation. Much debate has aroused...

Stock markets have seen severe price drops over the last 20 years such as the burst of the technology bubble. The mainstream view is that exuberance inflated prices before the burst. This study applies the Schwartz-Moon fundamental valuation model to find no conclusive evidence for overvaluation...

This paper documents how analyst recommendations are related to periods of bubbles. We find a strong positive relation between the concentration in analyst buy recommendations and bubble continuation in two settings. First, we show a positive association between the concentration in buy...

The Efficiency Market Hypotheses (EMH) imply rational investors and no asset mispricing in the medium run. This paper critically evaluates on the point of whether an asset price bubble is an irrational phenomenon that cannot be detected. Thereby, I review the existing literature and reflect on...

We extend the constant discount factor model with intrinsic bubbles developed in Froot and Obstfeld (1991) to account for serial correlation in dividend growth rates. We derive an exact analytical expression for both the present value stock price and an intrinsic bubble component when dividend...
