Research into spillovers involving emerging stock markets grew with the increasing openness and growth of emerging market economies (EMEs) as well as the crisis episodes in EMEs in the late 1990s that spread into other markets. This paper investigates which countries' equity markets are more important for the ASEAN-5 equity markets for the period 1990-2016. The findings in this paper show that returns and volatility spillovers are significant for the ASEAN-5 equity markets. In fact, these spillovers can account for more than half of the innovations in the ASEAN-5 national stock markets. Moreover, while the study reveals that innovations from Asian equity markets contribute more to innovations in the ASEAN-5 equity markets; innovations from advanced economies' equity markets remain important and innovations from non-Asian EMEs are not trivial. The results of this paper are robust against different scenarios and crisis episodes.
The development of the capital markets is changing the relevance and empirical validity of the efficient market hypothesis. The dynamism of capital markets determines the need for efficiency research. The authors analyse the development and the current status of the efficient market hypothesis with an emphasis on the Baltic stock market. Investors often fail to earn an excess profit, but yet stock market anomalies are observed and market prices often deviate from their intrinsic value. The article presents an analysis of the concept of efficient market. Also, the market efficiency evolution is reviewed and its current status is analysed. This paper presents also an examination of stock market efficiency in the Baltic countries. Finally, the research methods are reviewed and the methodology of testing the weak-form efficiency in a developing market is suggested.
This paper provides evidence of transmission of information from the U.S. and Japan to Korean and Thai equity markets during the period from 1995 through 2000. Information is defined as important macroeconomic announcements in the U.S., Japan, Korea, and Thailand. Using high-frequency intraday data, I focus the study on return volatility and trading volume because the implications of new information are much clearer than for returns. I find a large and significant association between emerging-economy equity volatility and trading volume and developed-economy macroeconomic announcements at short-time horizons. This is the first strong evidence of this sort of international information transmission. Previous studies' findings of at most weak evidence may be due to their use of lower frequency data and their focus on developed-economy financial market innovations as the measure of information.
An argument that contagion is the most significant risk facing the financial system and that Dodd¬Frank has reduced the government's ability to respond effectively.
The Dodd–Frank Act of 2010 was intended to reform financial policies in order to prevent another massive crisis such as the financial meltdown of 2008. Dodd–Frank is largely premised on the diagnosis that connectedness was the major problem in that crisis—that is, that financial institutions were overexposed to one another, resulting in a possible chain reaction of failures. In this book, Hal Scott argues that it is not connectedness but contagion that is the most significant element of systemic risk facing the financial system. Contagion is an indiscriminate run by short-term creditors of financial institutions that can render otherwise solvent institutions insolvent. It poses a serious risk because, as Scott explains, our financial system still depends on approximately $7.4 to $8.2 trillion of runnable and uninsured short-term liabilities, 60 percent of which are held by nonbanks.
Scott argues that efforts by the Federal Reserve, the FDIC, and the Treasury to stop the contagion that exploded after the bankruptcy of Lehman Brothers lessened the economic damage. And yet Congress, spurred by the public's aversion to bailouts, has dramatically weakened the power of the government to respond to contagion, including limitations on the Fed's powers as a lender of last resort. Offering uniquely detailed forensic analyses of the Lehman Brothers and AIG failures, and suggesting alternative regulatory approaches, Scott makes the case that we need to restore and strengthen our weapons for fighting contagion.
