This chapter presents several approaches for identifying and dating the speculative bubble on real estate market. Using the real estate price index (IPAI), statistical and structural approaches were combined in order to detect the existence of a bubble on the Moroccan real estate market. The results obtained affirm that the Moroccan real estate market experienced a speculative bubble during the period 2006–2008 explained mainly by the boom of credit during the same period. The use of the Markov switching model affirmed that the speculative bubble on Morocco is cyclic and consequently corroborates the critic formulated by Evans (1991) concerning the traditional approaches for the detection of financial bubbles. Thus, the analysis of the series of the bubble, extracted using the Kalman filter, affirms the existence of two regimes, namely an explosive regime and a normal regime. The first regime describes the periods of explosion of the bubble and lasts for about 9 quarters, while the second, lasting for 14 quarters, describes the periods of return to the average cycle.

The purpose of this paper is to examine the existence of rational speculative bubbles in the Middle East and North African (MENA) stock markets.

To complement shortcomings of the traditional bubble tests, such as unit root tests and cointegration tests, mainly relying on expectations of future steams of dividends, the authors employ fractional integration tests and duration dependence tests.

Despite recent extreme fluctuations of MENA stock markets, fractional integration tests built on autoregressive fractionally integrated moving average models do not support the possibility of bubbles in the MENA stock markets. Similarly, duration dependence tests based on nonparametric Nelson‐Aalen hazard functions not only reject the existence of bubbles but also support equality of hazard functions between domestic and the US‐based investors without regard to the rapid financial liberalization and integration in the MENA stock markets.

The reliable results of bubble tests of the MENA stock markets provide domestic and international investors as well as policy makers with invaluable benchmark to better understand the irregular and highly fluctuating stock market behaviors of the MENA stock markets compared to other developed and emerging stock markets. For domestic and international investors, the formal analysis of MENA stock markets behavior including rational speculative bubbles will help them in their portfolio decisions and hedging purposes. Similarly, the empirical results of bubble tests in the paper will be also helpful to policymakers in MENA countries to take actions to improve the functioning of these dynamic markets.

The purpose of this paper is to re-examine the presence of rational speculative bubbles in the Malaysian stock market in light of contradictory results presented in previous studies.

The authors use descriptive statistics, explosiveness tests and the duration dependence test. They use an expanded data set that encompasses at least two alleged bubble episodes addressing a significant limitation of previous studies. The authors use both monthly and weekly returns addressing concerns about the sensitivity of duration dependence test results to the use of monthly versus weekly returns, as well as a battery of alternative measures of returns.

The authors detect bubble footprints but they do not appear to be rational. They found no evidence of rational speculative bubbles over the sample period regardless of whether monthly or weekly returns was used. The authors suggest that if there were bubbles in the Malaysian stock market, they might have been caused by irrational investor behaviour. The authors’ results do not support the suggestion that the duration dependence test is sensitive to the use of monthly versus weekly returns.

Despite the absence of rational bubbles in the Malaysian stock market, the faint bubble footprints detected still suggest caution for investors, as the authors cannot categorically rule out the presence of irrational bubbles.

This paper clarifies conflicting results of previous studies. It also contributes to the literature on bubble testing by presenting new evidence from an emerging market refuting the claim that duration dependence test results are sensitive to the use of either weekly or monthly returns.

The authors' paper aims to deal with the question whether speculative bubbles are present in agricultural commodity prices.

The authors apply a regime switching regression model to test the hypothesis that agricultural prices contain periodically collapsing bubbles. Using daily futures prices for six agricultural commodities, the authors calculate net convenience yields from which price fundamentals are derived.

The authors discover pronounced deviations between observed prices and their fundamental values. However, they do not find evidence for the presence of periodically and partially collapsing speculative bubbles for five of six commodities. Except for soybeans, the signs and the significance of the estimated coefficients are not entirely in line with the predictions of the theoretical model.

The authors' study adds to the heated discussion on the impact of speculative behavior on agricultural commodity prices. So far, most contributions in the literature either use theoretical arguments for the (non‐) existence of bubbles or apply indirect tests which are plagued by low statistical reliability. In contrast, the authors apply a direct test. They find that the outcome of empirical bubble tests depends on the considered bubble type and on the testing procedure. In view of these ambiguities, definite statements on the presence of speculative bubbles as well as demands for limitations of speculative positions in commodity futures markets should be carefully reconsidered.

Speculative bubbles have been occurring periodically in local or global real-estate markets and are considered a potential cause of economic crises. In this context, the detection of explosive behaviors in the financial market and the implementation of early warning diagnosis tests are of critical importance. The recent increase in Brazilian housing prices has risen concerns that the Brazilian economy may have a speculative housing bubble. In the present chapter, we employ a recently proposed recursive unit root test in order to identify possible speculative bubbles in data from the Brazilian residential real-estate market. The empirical results show evidence for speculative price bubbles both in Rio de Janeiro and São Paulo, the two main Brazilian cities.

The upsurge of globalization has made investors cautious toward investing decisions, and, resultantly, sophisticated techniques of forecasting and analyzing the stock markets have emerged. Particularly, this trend has gained momentum in emerging economies. One such trend is to overcome the investing risks associated with formation of rational bubbles. Bubbles are formed when asset prices inflate to a very high level temporarily, and they ultimately burst. Investors may take advantage of this short-lived phenomenon and gain high returns, but may also suffer as the entire investing value declines when the bubble bursts. The purpose of this paper is to identify rational bubbles in the emerging capital markets of South Asian region.

The monthly data have been obtained from June 1997 to February 2018 for Pakistan, Bombay, Dhaka and Colombo stock markets, and supremum-Augmented Dicky Fuller test developed by Phillips and Yu (2011) has been utilized to identify the rational bubbles.

The results revealed the presence of rational bubbles in South Asian equity markets. The current study is of significant nature for the facilitation of investors in future-making investing decisions concerning with the formation of rational bubbles.

Several studies have been conducted on stock markets of developed regions. Specific bubble episodes, which occurred previously, have helped the researchers and investors in gaining plenty of insights. A lot of studies have been conducted on the SAARC region as well. But they have used the conventional unit root test for bubble identification and not used as extensive data as, in this study, have been taken. This research is aimed to study equity prices of the four stock markets to establish the fact that if rational bubbles exist in the index, they are reflected in the returns or not.

We tested for evidence of stock price bubbles in the Malaysian stock market from 1978 to 2004. Four different tests were used namely excess volatility tests, unit root/co-integration tests, duration dependence tests, and the intrinsic bubbles model. All four tests indicate that during the sample period, there was evidence of stock price bubbles. All tests results conform to the theoretical literature on asset price bubbles except for the results on the intrinsic bubbles model, which concludes that Malaysian investors under react to information on dividends. We find this result hardly surprising as anecdotal evidence does indicate that Malaysian investors place more importance on capital gains as compared to dividends. Although we do not go into a debate on whether authorities should be prick the bubble to stem its negative effects, we argue that transparent information dissemination will ensure that the stock market becomes more efficient in pricing stocks.

This article identifies the institutional factors behind both the emergence of a highly vulnerable financial system and the housing bubble that devastated it. The underlying premise is that the financial crisis was a market failure embedded in and caused by an institutional one. The failing institutions were academic, political and regulatory. The article shows how these institutions were fatally undermined, suggesting limits to the rationalization of finance capitalism. The perspective on financial crisis developed here recognizes the pressing need for reform of the financial markets, and also recommends institutional reforms as critical protections against future system failure.

The purpose of this paper is to test for the presence of bubbles in the US lodging/hotel real estate investment trust (REIT) subsector from 1994 to 2016. It also compares the profitability of a buy-and-hold strategy with several technical trading rules when applied to lodging REITs.

To investigate speculative bubbles, the sequential right-sided unit root tests of Phillips, Shi and Yu (2015a, b) are used.

The results confirm the possibility of the existence of multiple bubbles and explosive behavior in prices and the price-dividend ratio. One of the detected bubbles coincides with the financial economic crisis of 2008 using both measures. In addition, several technical rules are found to be superior to a naïve buy-and-hold strategy even after adjusting for risk.

These findings will be of interest to policy makers, who can use such models as an early alert to take anticipative action to avoid bursting of bubbles and consequent negative effects on the economy. The findings also provide important information to investors attempting to devise trading rules that utilize the signals from bubble detection, as well as to hotel executives devising policies aimed at reducing risk and creating more firm value to maximize shareholder wealth. Moreover, valuation and bubbles are important to lenders and creditors who use assets as collaterals for financing hotel REITs.

Hotels are a unique hybrid of retail and housing that combine operating business with real estate. This paper is the first to investigate speculative bubbles in lodging REITs.

The purpose is to review what is known about property bubbles and their causes.

The method has been to review the literature on bubbles in the property and other asset markets to examine their likely causes and whether there are specific aspects of the property market that make it more prone to bubbles.

The property market has features that make it susceptible to bubbles, particularly inelasticity in supply and the absence of short selling. Bubbles can develop where there are heterogeneous beliefs. The way in which property tends to be financed helps to facilitate bubbles and transmit their effects onto the wider economy.

The collapse in property prices after the financial crisis of 2008, like previous bubble collapses, has inflicted serious damage on the wider economy through losses of banks' capital, reductions in lending, and increased risk aversion. Understanding why bubbles exist offers the potential to devise policies to limit the impact of their collapse.

Much of the literature on asset bubbles is based on securities markets. It is important to recognise the differences between the property market and securities markets, particularly how investment is financed.
