Share Prices and Macroeconomic Factors

The APT with macroeconomic factors put forward by Chen, Roll and Ross (1986) was tested using monthly Australian sectoral share-price indexes for 1980–1994. The inflation rate was found to be consistently priced. The significance of other factors was found to depend on the choice of sample period and estimation method. The model was compared to both an APT with artificial factors and the CAPM. Both versions of the APT were found to clearly out-perform the CAPM but neither version of the APT was clearly superior to the other in terms of both within- and out-of-sample explanatory power.     

The impact of exchange rates on stock market returns: new evidence from seven free-floating currencies

This paper provides evidence of a significant exchange rate effect on stock index returns using data from seven selected countries practicing free-floating exchange rate regimes. This research uses parity and asset pricing theories, thus placing it within the monetary-cum-economics framework for international asset pricing. In this study, we apply a system of seemingly unrelated regression to control for unobserved heterogeneity and cross-sectional dependence. The findings constitute evidence of a statistically significant exchange rate impact on stock index returns across selected countries. These findings can be considered as falling under the arbitrage pricing approach of the international capital asset pricing model of Solnik who also used the parity-theoretical framework on exchange rate determination.     

A careful re-examination of seasonality in international stock markets: Comment on sentiment and stock returns

In questioning Kamstra, Kramer, and Levi’s (2003) finding of an economically and statistically significant seasonal affective disorder (SAD) effect, Kelly and Meschke (2010) make errors of commission and omission. They misrepresent their empirical results, claiming that the SAD effect arises due to a “mechanically induced” effect that is non-existent, labeling the SAD effect a “turn-of-year” effect (when in fact their models and ours separately control for turn-of-year effects), and ignoring coefficient-estimate patterns that strongly support the SAD effect. Our analysis of their data shows, even using their low-power statistical tests, there is significant international evidence supporting the SAD effect. Employing modern, panel/time-series statistical methods strengthens the case dramatically. Additionally, Kelly and Meschke represent the finance, psychology, and medical literatures in misleading ways, describing some findings as opposite to those reported by the researchers themselves, and choosing selective quotes that could easily lead readers to a distorted understanding of these findings.

Dangers in data adjustment: the case of rights issues and returns

In this paper we alert researchers to the potential for unrecognised errors in using adjusted price and daily return data. This problem is illustrated by considering the case of ex‐rights price adjustments. We present five alternative adjustment procedures that would be expected to generate similar results. We show, however, that these procedures result in significantly different dilution factors and returns. Our investigations suggest that the problem is associated with the theoretical valuation of the rights. In a substantial proportion of cases, the standard textbook model is inappropriate because of the non‐standard nature of the rights issue. Correcting for these non‐standard cases is a non‐trivial task since they constitute more than half of the issues. The extent of this problem does not appear to be well recognised. Deletion of non‐standard rights issues eliminates extreme values in dilution factors, but statistically significant differences remain. Our moral is simple; uncritical acceptance of data 'as is' from computer data files may lead researchers to erroneous conclusions. It also seems noteworthy that the standard textbook model of rights pricing only applied to a minority of Australian rights issues over recent years. This result has implications for the calculation of EPS under AASB 1027. As a by‐product, our analysis suggests that the ex‐rights daily return is close to zero.

Commonality in hedge fund returns: Driving factors and implications

We measure the commonality in hedge fund returns, identify its main driving factor and analyze its implications for financial stability. We find that hedge funds’ commonality increased significantly from 2003 until 2006. We attribute this rise mainly to the increase in hedge funds’ exposure to emerging market equities, which we identify as a common factor in hedge fund returns over this period. Our results show that funds with a high commonality were affected disproportionately by illiquidity and exhibited negative returns during the subsequent financial crisis, thereby providing little diversification benefits to the financial system and to investors.     

Dynamic Effects of Financial Openness on Economic Growth and Macroeconomic Uncertainty

This paper examines the dynamic effects of financial integration and foreign direct investment (FDI) on economic growth and macroeconomic uncertainty. Using the pooled mean group autoregressive distributed lag approach to annual data over 1975-2007 for ninety developing countries, we find that financial integration contributes to faster economic growth and lower growth uncertainty in the long run. The evidence also shows considerable heterogeneity in the short run. In addition, we find that FDI impedes output growth but mitigates uncertainty in output and consumption growth in the long run. In the short run, FDI has an average negative effect on growth and negligible effect on growth uncertainty, but there are large cross-country differences in response to FDI integration.     

Commonality in returns,order flows,and liquidity in the Greek stock market

Using a unique high-frequency data-set on a comprehensive sample of Greek blue-chip stocks, spanning from September 2003 through March 2006, this note assesses the extent and role of commonality in returns, order flows (OFs), and liquidity. It also formally models aggregate equity returns in terms of aggregate equity OF, in an effort to clarify OF's importance in explaining returns for the Athens Exchange market. Almost a quarter of the daily returns in the FTSE/ATHEX20 index is explained by aggregate own OF. In a second step, using principal components and canonical correlation analyses, we document substantial common movements in returns, OFs, and liquidity, both on a market-wide basis and on an individual security basis. These results emphasize that asset pricing and liquidity cannot be analyzed in isolation from each other.     

Habit persistence: Explaining cross-sectional variation in returns and time-varying expected returns

This paper uses an iterated GMM approach to estimate and test the consumption based habit persistence model of Campbell and Cochrane [Campbell, J.Y., Cochrane, J.H., 1999. By force of habit: A consumption-based explanation of aggregate stock market behavior. Journal of Political Economy 107, 205–251] on the US stock market. The empirical evidence shows that the model is able to explain the size premium, but fails to explain the value premium. Further, the state variable of the model – the surplus consumption ratio – explains counter-cyclical time-varying expected returns on stocks. The model also produces plausible low real risk-free rates despite high relative risk aversion.     

Output and expected returns

This paper shows for 1929–2003 U.S. data and also for international G-7 data that the ratio of share prices to GDP tracks a large fraction of the variation over time in expected returns on the aggregate stock market, capturing more of that variation than do price–earnings and price–dividend ratios and often also providing additional information about excess returns. The price–output ratio tracks long-term U.S. cumulative stock returns almost as well as the cay-ratio of Lettau and Ludvigson [2001a. Journal of Finance 56, 815–849, 2005. Journal of Financial Economics 76, 583–626], although the cay-ratio tracks variation in U.S. excess returns better. The price–output ratio, however, involves no parameter estimation and is easily constructed for non-U.S. countries.     

保险周期的影响因素分析——基于全球范围保险公司面板数据的研究

现有理论研究从已有损失经验、承保能力约束和一般经济因素三方面解释保险周期产生的原因,而已有实证检验多使用某一个国家(地区)的加总时间序列数据进行分析。本文使用2007～2016年全球各国保险公司的财务面板数据,构建差分模型进行面板固定效应回归,检验现有主流的解释保险周期假说的成立性,并验证高收入国家(地区)和中低收入国家(地区)的保险周期在传导机制上是否存在结构性差异。实证结果表明,已有损失经验是保险周期的显著影响因素,且该因素在高收入国家(地区)与中低收入国家(地区)之间不存在结构性差异,而承保能力约束对保险周期的影响在高收入国家(地区)与中低收入国家(地区)之间存在结构性差异。本文使用企业层面数据对几种主流理论模型解释加以实证检验,更加切合理论模型的行为假设,同时本文所构建的结构性差异差分模型揭示了中低收入国家(地区)保险周期与高收入国家(地区)的差异性。     

Sources of Systematic Risk in Futures and Spot Markets: A Study of Market Integration

This article explains the implications of asset market integration for the decision making process of market participants and tests the integration between futures and spot markets. Integration is investigated with respect to the hypothesis that the sources of systematic risk in futures and spot markets command identical risk premia. While the futures and the spot markets for currencies and equities are integrated, we present new evidence that the futures and commodity spot markets are segmented. Such results are of primary importance to investors who use asset pricing models to adjust the risk-return trade-off of their portfolio and evaluate portfolio performance.     

Equity returns,bond returns,and the equity premium in the German capital market

This article reviews the empirical evidence for equity returns, bond returns, and the equity premium in the German capital market for the period from 1870 to 1995. Taken together, the studies reviewed provide convincing evidence that over longer investment periods, average equity returns have been higher than average bond returns. These excess returns, however, have been highly volatile and negative in many years, illustrating the higher risk of equity investments. Moreover, market timing had a major positive or negative impact on overall returns. Despite the historical evidence of a substantial equity premium there is still little equity investment by German households.     

Serial correlation and seasonality in the real estate market

In this article, a two-step, two-sample method and a Bayesian method are proposed to estimate the serial correlation and the seasonally of the price behavior of the residential housing market. The Bayesian method is found to be superior to the alternative two-step methods. The empirical results based on the Bayesian approach support the rejection of the random-walk hypothesis in the real estate market. Seasonality is not significant; however, there is still a clear indication that the returns associated with seasonal dummies are strongest in the second quarter, with the first quarter following closely.     

Displacement risk and asset returns

We study asset-pricing implications of innovation in a general-equilibrium overlapping-generations economy. Innovation increases the competitive pressure on existing firms and workers, reducing the profits of existing firms and eroding the human capital of older workers. Due to the lack of inter-generational risk sharing, innovation creates a systematic risk factor, which we call “displacement risk.” This risk helps explain several empirical patterns, including the existence of the growth-value factor in returns, the value premium, and the high equity premium. We assess the magnitude of displacement risk using estimates of inter-cohort consumption differences across households and find support for the model.     

Retail clientele and option returns

Does the retail clientele matter for option returns? By delta-hedging options and trading straddles, thus allowing a focus on volatility, this paper empirically shows that a higher retail trading proportion (RTP) is related to lower option returns. Long-short portfolios involving options on low and high RTP stocks generate significantly positive abnormal returns. The results suggest that retail investors speculate and pay a lottery premium on the expected future volatility, resulting in more expensive options with higher implied volatilities.
