Exchange rates and oil prices: A multivariate stochastic volatility analysis

This paper uses the multivariate stochastic volatility (MSV) and the multivariate GARCH (MGARCH) models to investigate the volatility interactions between the oil market and the foreign exchange (FX) market, in an attempt to extract information intertwined in the two for better volatility forecast. Our analysis takes into account structural breaks in the data. We find that when the markets are relatively calm (before the 2008 crisis), both oil and FX markets respond to shocks simultaneously and therefore no interaction is detected in daily data. However, during turbulent time, there is bi-directional volatility interaction between the two. In other words, innovations that hit one market also have some impact on the other at a later date and thus using such a dependence significantly improves the forecasting power of volatility models. The MSV models outperform others in fitting the data and forecasting exchange rate volatility. However, the MGARCH models do better job in forecasting oil volatility.     

Intangible capital distribution in China

This paper aims to examine the distribution dynamics of intangible capital investment across Chinese regions and hence contributes to the understanding of China’s regional development. A nonparametric approach is adopted to investigate the long-run distribution dynamics. Intertemporal dynamics and spatial conditional dynamics are analysed to explore the impacts of the global financial crisis and knowledge spill-over on intangibles’ distribution. It is shown that the formation of convergence clusters persists in the long run. High levels of investment tend to be concentrated in a few coastal regions while investment in most Chinese regions is projected to be low. External shocks exert an adverse effect: The post-global financial crisis transition dynamics indicate that most regions tend to converge towards a lower level than the pre-crisis dynamics imply. Finally, knowledge spill-over in the context of intangibles is identified to be an important factor that helps mitigate regional imbalance.     

Does diversification add firm value in emerging economies? Effect of corporate governance

Using 205 Taiwanese firms spanning five years, this research examines how corporate governance factors specific to emerging economies determine the extent of diversification and moderate its performance. The analyses reveal that controlling family ownership is significantly associated with a greater extent of diversification, which impairs firm value. Conversely, domestic bank ownership significantly decreases diversification, which in turn increases diversification performance. These findings present the evidence of controlling family entrenchment through diversification and the significant role domestic banks play in the principal–principal corporate governance framework.     

Shareholder litigation and toxic releases

We examine the environmental impact of the staggered adoption of universal demand laws by 23 U.S. states between 1989 and 2005. Universal demand laws impede derivative lawsuits and thus undermine shareholder oversight of corporate environmental performance. We find that weakened litigation rights for shareholders are positively associated with the release of toxic chemicals by firms. The effect is stronger for firms with weak governance, and environmental mismanagement by firms after the passage of the laws lead to poorer financial performance. Overall, our findings imply that derivative lawsuits by shareholders are not frivolous, as is often asserted. Rather, they act as an effective mechanism of corporate governance.     

The Role of Bank Funding Diversity: Evidence from Vietnam

This paper analyzes the impact of bank funding diversity on bank income and risk in emerging markets. We utilize a data sample which includes 37 Vietnamese banks for the period 2006–2015. We find that banks with diversified funding sources have advantages in improving profitability. However, we also find that banks with higher funding liquidity tend to participate in more risk‐taking activities. The findings contradict the notion that banks which have access to diversified funding sources are able to improve profitability without increasing their risk‐taking. The study has strong implication for banks managers and prudential authorities in emerging markets.     

Portfolio concentration and fund manager performance

This research examines the relationships among portfolio concentration, fund manager skills, and fund performance in Taiwan's equity mutual fund industry, yielding several empirical findings as follows. First, after controlling for other factors, concentrated equity funds tend to have smaller net asset values, larger fund flows, higher turnover rates, and a younger age and prevail in smaller fund families. Second, concentrated fund managers buy and sell stocks more smartly based on economic trends or market factors than do diversified fund managers, i.e., they have better market‐timing abilities. Third, only partial evidence supports the premise that concentrated equity funds have better next‐quarter risk‐adjusted performances than do diversified ones, as these fund managers' skills positively correlate to risk‐adjusted fund performance. Fourth, fund managers who have better stock‐picking abilities and intensively invest in certain industries generally exhibit better Carhart's alpha in the next quarter than do other fund managers. Fifth, fund managers' stock‐picking abilities more closely relate to long‐term performance than do their market‐timing abilities. Lastly, positive performance persistence is much stronger than negative performance persistence, but concentrated funds do not have stronger performance persistence than do diversified funds.     

Cointegration and the optimal hedge ratio: the general case

This note evaluates the effects of omitted cointegration relationship between spot and futures prices on optimal hedge ratio and hedging effectiveness. It is found that the omission tends to produce a smaller hedge ratio. However, the loss of hedging effectiveness may be minimal.     

The impacts of benefit plans on employee turnover: a firm-level analysis approach on Taiwanese manufacturing industry

Employee turnover is a serious problem and the question of how to retain highly talented and valued people is very important. Previous employee turnover studies were mostly focused on the individual level but rarely from the standpoint of the business or firm. This study examines the impacts of four kinds of benefit plans on firm-level employee turnover issues, namely, retirement fund, pension, severance pay and fringe benefit. The present study uses the Census Bureau Employment Movement Survey of the Directorate General of Budget, Accounting and Statistics in Taiwan. The two models used to examine the overall manufacturing industry were: (1) the inducement model which tests the ‘with or without’ effect; and (2) the investment model which tests the ‘the more the better’ effect. Results reveal that, with respect to the firm's employee turnover rate, retirement fund and fringe benefits are negative while severance plans are significantly positive. These results are consistent with the transaction costs theory that total expenditure on these plans to retain employees (bureaucratic cost) is less than the market arrangements (transaction cost). In addition, the impact of pension plans is negative in respect of employee turnover in larger or more highly educated firms, but positive in firms with a lower educational level. Moreover, the firm size is negative while the firm's average employees' educational level is positive with respect to the workforce leaving their jobs. These results are consistent with the perspective of resource-based theory and human capital theory. Incidentally, this study also reveals insignificant differences between the ‘with or without’ effect and the ‘the more the better’ effect existing as a sub-group industry rather than across the entire industry.
