A note on the expectations hypothesis at the founding of the Fed

One of the most influential tests of the expectations hypothesis is Mankiw and Miron [Q. J. Econ. 101 (1986) 211], who found that the spread between the long-term and short-term rates provided predictive power for the short-term rate before the Fed's founding but not after. They suggested that the failure of the expectations hypothesis after the Fed's founding was due to the Fed's practice of smoothing short-term interest rates. We show that their finding that the expectations hypothesis fares better prior to the Fed's founding is due to the fact that the test they employ tends to generate results that are more favorable to the expectations hypothesis during periods when there is extreme volatility in the short-term rate.     

Presenting hypothesis testing by analogy

Auditing students often have difficulty with hypothesis testing. In this article, a concise approach for presenting hypothesis testing is discussed. Specifically, the author shows that the construction of an hypothesis test for the mean per-unit estimator is analogous to the formulation of such a test for auxiliary estimators. Because these tests are comparable, the approach encompasses a logical progression from the mean per-unit estimator to the auxiliary estimators. This approach enables students to perceive the similarities among these estimators and to better understand and assimilate the subject matter.     

思想政治理论课在教学中的情感教育模式

高校思想政治理论课教学既是对大学生进行的马克思主义思想政治理论的认知教育,同时更是对大学生进行的马克思主义情感教育,是在使学生提高思想认识的基础上,形成马克思主义思想。在思想政治理论课教学中发挥教师的主导作用,提高马克思主义理论的说服力、感染力,在教学过程中真正做到"情"、"理"相融,就要发挥情感教育的作用,合理运用情感教育模式。     

Firm growth and efficiency in the banking industry: A new test of the efficient structure hypothesis

In this paper we propose a new test of the efficient structure (ES) hypothesis, which predicts that efficient firms come out ahead in competition and grow as a result. Our test has significant advantages over existing ones, because it is more direct, and can jointly test the so-called quiet-life hypothesis, which predicts that in a concentrated market firms do not minimize costs. We then apply this test to large banks in Japan. Consistent with the ES hypothesis, we find that more efficient banks become larger. We also find that market concentration reduces banks’ efficiency, which supports the quiet-life hypothesis. These findings imply that there is an intriguing growth–efficiency dynamic throughout banks’ life cycle, although our findings also suggest that the ES hypothesis dominates the quiet-life hypothesis in terms of economic impact.     

The Determinants of Debt Maturity: The Case of Bank Financing in Singapore

This study presents important international evidence by examining the determinants of debt maturity of listed firms in Singapore, a major financial center in Asia. We focus on bank debt because it is the principal source of financing for most Singapore firms. We find that consistent with the contracting-cost hypothesis, firms with greater growth opportunities rely more heavily on short-term bank debt whereas larger firms are more likely to use long-term bank debt. In contrast, we find no strong support for either the tax or signaling hypotheses.     

Some evidence on Ross' resolution irrelevancy hypothesis

This research attempts to discriminate empirically between the predictable events and resolution irrelevancy hypotheses as both pertain to abnormal stock price performance around regular and special proxy statement mailing dates and the related shareholder meeting dates. We find no evidence that these events result in the positive wealth effects suggested by the predictable events hypothesis. We do find evidence of increased idiosyncratic stock price volatility or information flow around special meeting proxy statement mailing dates and special meeting dates. Thus, our evidence supports the resolution irrelevancy hypothesis.

A Market Efficiency Comparison of Islamic and Non-Islamic Stock Indices

This article examines the martingale difference hypothesis (MDH) and the random walk hypothesis (RWH) for nine conventional and nine Islamic stock indices: Asia-Pacific, Canadian, Developed Country, Emerging, European, Global, Japanese, UK, and United States. It investigates whether Islamic stock indices are more, less, or as efficient as their conventional counterparts. We test four sub-periods of bullish and bearish stock markets, together with the financial meltdown and its recovery, over the period 1997–2012. We use the Escanciano and Lobato’s (2009) automatic portmanteau test (AQ) and Deo’s (2000) test for the MDH. We also apply the automatic variance ratio test (AVR) developed by Choi (1999) and Kim (2009) for the RWH. Over the period from 1997 to 2012, we find that three conventional indices (Europe, Japan, and UK) are efficient, but that none of the Islamic indices are efficient in these markets. During the recent financial crisis, our results indicate slightly more efficiency for the Islamic indices than their conventional counterparts. Our study finds that overall the conventional indices are more efficient than their Islamic counterparts. Nevertheless, during periods of general downturns the Islamic indices have shown the same level of efficiency as their counterparts. Furthermore, it appears that during the last two sub-periods under study, the Islamic indices have moved toward efficiency, displaying the same level of efficiency as their counterparts.     

Risk Shift Following Dividend Change Announcement: The Role of Trading Volume

This study investigates the role of the trading volume in explaining the shift of firm's total and systematic risk when a dividend change is announced. We compared the differential interpretation hypothesis and pre-announcement disagreement hypothesis with more than 20,000 samples collected for 30 years. We found that the total risk generally increases regardless of the level of abnormal trading volume, which supports the differential interpretation hypothesis. We also found a positive relationship between announcement-period abnormal trading volume and post-announcement changes in beta, which is only consistent with the differential interpretation hypothesis. However, the decrease in beta for the majority of sample firms is only consistent with the pre-announcement disagreement hypothesis.     

Time-variation in term premia: International survey-based evidence

Using a large, previously unexplored data set of survey-based interest rate forecasts that covers a broad range of countries, this paper re-examines the expectations hypothesis of the term structure of interest rates. We find that survey-based interest rate forecasts outperform not only a random walk forecast, but also outperform forecasts from forward rates. When using these superior survey-based forecasts in a modified expectations hypothesis test, the expectations hypothesis is rejected for fewer countries, at lower significance levels, and has greater explanatory power than when using a traditional forward rates-based test. We furthermore document strong time-variation in the term premia, which is an important reason why the traditional expectations hypothesis test is rejected so frequently. This time-variation seems to arise from the changing attitudes towards risk among market participants and as a compensation for the change in liquidity in the term structure. Finally, we find that generalizing findings from earlier U.S. studies to other countries may lead to bias in the true economic relationships in these countries.
