Interdependence and Volatility Spillovers Under Market Liberalization: The Case of Istanbul Stock Exchange

This paper analyzes stock returns and volatility relations between the Istanbul Stock Exchange (ISE) and the global market as represented by stock markets in the US, the UK, Japan and Germany. Results from monthly data and multivariate cointegration tests suggest that the ISE became significantly integrated in the global market only in the period following market liberalization in late 1989. We also find evidence based on GARCH estimations that capital liberalization actually mitigated, rather than intensified, volatility in the ISE. Our results further suggest that the Asian crisis in mid‐1997 and the consequent Russian economic meltdown in mid‐1998 are partly responsible for the recent excessive volatility in the Turkish market. The results also identify the US and the UK markets as dominate sources of volatility spillovers for the ISE, even in the period following the Asian‐Russian crises. Consequently, it appears that the two matured markets of the US and the UK shoulder significant responsibility for the stability and financial health of smaller emerging markets like the ISE.     

Detecting income-smoothing behaviors of Turkish listed companies through empirical tests using discretionary accounting changes

Flexibility when selecting accounting methods sometimes motivates managers to choose accounting methods or to change employed ones in order to increase, decrease or smooth income figures. In this study, income-smoothing behaviors of Turkish listed companies are detected through empirical tests using discretionary accounting changes (DACs). Parallel to the study conducted by Moses [Moses OD. Income smoothing and incentives: empirical tests using accounting changes. The Accounting Review 1987;11(2):358–77], income smoothing is accepted as one motivation of DACs and the sample firms are classified as smoothers and non-smoothers by using Moses’ smoothing behavior index. Results show that possible motivations of DACs are income smoothing, economical characteristics of the periods in which the DACs are made, and the desire of Turkish firms to have net incomes close to zero.     

Return Predictability of Turkish Stocks: An Empirical Investigation

Employing the portfolio method and cross-sectional regressions, this paper provides a comprehensive analysis of stock return predictability in Turkey from January 1997 to July 2011. In the risk-related predictors, we found predictive power for beta, total volatility, and idiosyncratic volatility. The "cheapness" variable, book-to-market ratio, is the most important return predictor for the stocks traded on the Istanbul Stock Exchange (now part of the Borsa Istanbul). Grouping the stocks as small and large according to the median value of the market capitalization of the stocks adds important insights to the analysis. Our results show the set of large stocks on the Istanbul Stock Exchange to be the least predictable set of stocks.

Developing countries converging with developed-country accounting standards: Evidence from South Africa and Mexico

I examine the usefulness (relevance and timeliness) of earnings announcements in two emerging markets, the Johannesburg Stock Exchange (JSE) and the Bolsa Mexicana de Valores Stock Exchange (BMV). A weighted least-squares regression is used to test the association of book values of earnings and equity with firm market value. I find that, on JSE and BMV, earnings and/or book value of equity are value relevant in explaining stock prices. I also find that this association is greater in 2000 as compared to 1998 on the BMV. Regarding timeliness, I find that earnings announcements are accompanied by unusually different returns on JSE, but not on BMV. Market infrastructure, specifically insider-trading rules, may explain BMV results. I suggest that accounting and market infrastructure interact and that such interaction is valuable input to the Financial Accounting Standards Board (FASB) and International Accounting Standards Board (IASB) in their deliberations regarding one set of accounting regulations for all countries.

Extent of corporate governance disclosure by banks and finance companies listed on Nepal Stock Exchange

Corporate governance disclosure has seen renewed interest by researchers, policy makers, and regulating bodies internationally, but has remained only an emerging construct in Nepal. The primary purpose of this study was to assess the extent of mandatory corporate governance disclosure in Nepal. The secondary purpose was to examine the associations between the extent of disclosures and five firm-specific characteristics. The third purpose was to assess the significant determinants to explain variations of disclosures. The study's sampling frame consisted of 125 banking and finance companies listed on Nepal Stock Exchange. A sample size of 59 companies was randomly selected. On average, companies disclosed 91% of items in the mandatory category, 48% in the voluntary category, and 74% in total. A significant positive correlation existed between governance disclosures and firm characteristics of size, leverage, and foreign ownership. There was no significant relation between governance disclosure and listing age or profitability. With regards to determinants, bank size was a significant predictor of governance disclosure. Three regression models for total disclosures (DScore), mandatory disclosures [DScore (M)], and voluntary disclosures [DScore (V)] with three predictors of size, leverage, and foreign ownership were significant and explained 47%, 24%, and 54% variations respectively in total, mandatory, and voluntary corporate governance disclosures in Nepal. This research provides guidelines to policy makers and standard setters for developing future regulations and accounting policies.
