Diversification strategies and firm performance in Vietnam

This paper is based upon the assumption that a firm's profitability is determined by its degree of diversification which is, in turn, strongly related to the antecedent decision to carry out diversification activities. This calls for an empirical approach that permits the joint analysis of the three interrelated and consecutive stages of the overall diversification process: diversification decision, degree of diversification and outcome of diversification. We apply parametric and semi‐parametric approaches to control for sample selection and the endogeneity of the diversification decision in both static and dynamic models. For the analysis, we use the census dataset on the whole firm population in Vietnam, as a representative of transition countries. After controlling for industry fixed‐effects, the empirical evidence from the firm‐level data shows that diversification has a curvilinear effect on profitability: it improves firms’ profit up to a point, after which a further increase in diversification is associated with declining performance. This implies that firms should consider optimal levels of product diversification when they expand their product offerings beyond their core business. Other noteworthy findings include the following: (i) the factors that stimulate firms to diversify do not necessarily encourage them to extend their diversification strategy; (ii) firms that are endowed with highly technological resources and innovation investment are likely to successfully exploit diversification as an engine of growth; and (iii) while industry performance does not have a strong influence on the profitability of firms, it impacts their diversification decision as well as the degree of diversification.     

Corporate social responsibility (CSR) and corporate diversification: do diversified production firms invest more in CSR?

A diversification strategy increases the range of stakeholder demands and social issues related to a firm’s operation. Examining the consequence of production diversification strategy at a broader level, not only (short-term) financial performance but also long-term performance, as proxied by corporate social responsibility (CSR), is surprising. We show that a firm’s production diversification is associated with stronger engagement in CSR, particularly for unrelated diversification. And the higher level of diversification is, the more investment in CSR. Our findings lead to the interesting questions regarding diversification discount and the value of unrelated diversification, which has often been criticized because of its negative impact on short-term financial performance.

多元化战略、企业研发支出与企业绩效的关系

以2009—2011年我国沪深两市制造业上市公司为研究样本,考察了多元化战略对企业R&D支出的影响,以及多元化战略对企业R&D支出与企业绩效间关系的调节作用。结果显示:多元化战略与企业R&D支出显著负相关;无论用ROA还是Tobin′s q度量企业绩效,企业R&D支出都与企业绩效显著正相关。进一步分析的结果表明:企业R&D支出与企业绩效的关系受多元化战略的调节,而两者间显著的正相关关系仅在专业化企业中存在。稳健性检验结果表明,上述研究结论不受样本选择的影响。     

Does it really pay to do better? Exploring the financial effects of changes in CSR ratings

Previous literature on the link between corporate social responsibility (CSR) and financial performance has focused mainly on the financial implications of a firm’s level of CSR without considering the potential effects on financial performance of variations in CSR rating. We try to fill this gap by studying whether variations in a firm’s CSR rating affect systematic risk, firm value, and portfolio performance. First, our results show that an increase in firms’ CSR efforts, as reflected by an increase in their CSR ratings, significantly reduces systematic risk. Second, a positive variation in CSR ratings significantly improves firm value. Finally, from a portfolio perspective, a strategy that consists of buying stocks that have experienced a CSR ratings increase and selling stocks that have experienced a CSR ratings decrease (or remain stable) leads to lower financial performance. Taken together, our findings provide new evidence and financial implications for firms and portfolio managers.     

The impact of product diversification strategy on the corporate performance of large Spanish firms

We analyze the impact of product diversification on performance. This topic has been discussed in the literature, and there is no consensus so far as to the significance or the direction of the impact. Performance is measured using Tobin's q for a sample of 103 large, non-financial Spanish firms (1992–1995). Diversification is measured by means of a categorical variable, as suggested by Varadarajan. The principal results indicate that the firms with intermediate levels of product diversification have the highest performance, while the firms with low and high levels of diversification show significantly lower performance, which performance is not significantly different between them.     

Owner-managers and firm performance during the asian and global financial crises: evidence from Korea

We examine the performance of the Korean owner-managers during the 1997?1998 Asian financial crisis and the 2008?2009 global financial crisis to establish whether they overcome the unexpected exterior shocks better than employed managers. We find that the owner-managers record a significantly greater performance during the crises, and especially during the latter period. Moreover, our results suggest that such a tendency comes from the owner-managers’ superior investment decisions. Our paper thus highlights the role of owner-managers by studying their performance during the Korean economic crisis periods. (JEL G01, G32, G34)     

NORTH–SOUTH TRADE WITH MULTINATIONAL FIRMS AND INCREASING PRODUCT VARIETY*

We present a model of North–South trade with multinational firms and increasing product variety. Firms engage in innovative R&D to develop new product varieties in the North, and foreign affiliates of multinational firms engage in adaptive R&D to learn how to produce product varieties in the South. We find that a shift to stronger protection of intellectual property rights in the South induces foreign affiliates of multinational firms to increase their R&D expenditures, results in a faster rate of technology transfer within multinational firms, and increases long‐run consumer welfare in both regions.     

Bank loans vs. trade credit

Using a World Bank dataset of Chinese firms, we investigate the relative importance of bank loans and trade credit in promoting firm performance. To deal with possible endogeneity issues, we employ distinct and separable instrumental variables for bank loans and trade credit. We find that access to bank loans is central to improving firm performance and growth, while the availability of trade credit is much less important. Our results suggest that trade credit cannot effectively substitute for bank loans. Overall, our findings suggest the need for further development of China's formal financial institutions, which would enable the non‐state sector to grow much faster than it has grown in recent decades.     

Shouldn't all eggs be putted in one basket? A portfolio model based on investor sentiment and inertial thinking

In the portfolio choice literatures and the financial market, diversification and concentration are the focus of debate of philosophers. In this paper, we develop a model of portfolio choice to integrate the diversification strategy and the concentration strategy. Our model relies on the concepts of investor sentiment and inertial thinking. The results show that: Generally, when the level of sentiment is relatively low, an investor who is affected by sentiment and inertial thinking may do a well-diversified investment the same as the rational investor. When the level of sentiment is high enough, the investment strategies including diversification and concentration are complex and volatile. Quantitative results for either diversification or concentration investment are given for all cases in the paper.

货币薪酬能激励高管承担风险吗

有关“风险承担”（risk taking）的研究是近年来特别是全球金融危机背景下财务学研究的热点问题之一。本文研究结果表明：（1）货币薪酬激励的增加能提升高管承担风险的水平;（2）最终控制人性质和公司成长性会影响两者之间的关系,在国有企业以及公司成长性较低的公司,货币薪酬激励与风险承担之间的正相关关系较弱;（3）风险承担水平的提高能促进公司绩效的提升;（4）进一步研究发现,风险承担在高管薪酬激励与企业绩效之间发挥中介效用作用。这些结论在采用两阶段最小二乘法（2SLS）和三阶段最小二乘法（3SLS）处理内生性问题等稳健性测试后依然成立。因此,本文从“风险承担”这一新的视角深化了有关高管薪酬激励降低代理问题并提升公司绩效的研究,也为中国上市公司尤其是国有上市公司高管薪酬契约设计的有效性提供了借鉴和参考价值。     

Diversification and tunneling: Evidence from Indian business groups

We provide evidence suggesting an important yet largely unexplored motive for the diversified structure of emerging economy business groups is to facilitate expropriation of minority shareholders by controlling insiders through tunneling. Using firm level panel data from India, and defining the core firm of a group as the one with the largest asset base, we find that the relatedness of the activity of a group affiliate to the activity of the core firm is correlated with the wedge between control and cash flow rights of insiders as well as with the opacity in insider ownership. Firms with ownership-control wedge lower and ownership opacity higher relative to a group’s core firm are more likely to be in activities unrelated to that of the core firm. Our findings are strengthened by evidence of tunneling in the same direction, from affiliates with wedge equal to or higher than that of the core firm to affiliates with wedge lower than that of the core firm. Taken together this suggests an expropriation motive for diversification: affiliate firms are located away from a business group’s core firm to serve as destination points for funds tunneled from the group’s core.     

Further evidence on international Islamic and conventional portfolios diversification under regime switching

This article investigates the comparative performance of International Islamic and conventional portfolio diversification across different financial market regimes and provides an optimal choice from an American investor’s viewpoint during the period 2002–2014. Using a bootstrap-based stochastic dominance (SD) test and monthly MSCI prices of Islamic stock market indices and their conventional counterparts in 38 countries from North and Latin America, Europe and Asia-Pacific regions, we find that SD relationships between Islamic and conventional optimal-diversified portfolios change systematically according to investment region and market regime. Essentially, for all regimes, US investors are indifferent between Islamic diversification and its conventional counterpart, which implies that arbitrage diversification opportunities are rare and short lived in all regions. However, across all regions, especially in a crisis regime, Islamic portfolio diversification can be a good substitute for conventional diversification. Islamic portfolio diversification in North and Latin America, Europe and Global regions is an optimal choice for the risk-averse American investors. Finally, results imply that portfolio diversification among Islamic market indices can be a good hedge, offering investors superior investment alternatives during any financial meltdown or economic slowdown due to the conservative nature of Sharia-compliant investments.     

Debt shifting and ownership structure

Previous theoretical studies on the debt shifting behavior of multinationals have assumed affiliates of multinationals to be wholly owned. We develop a model that allows a multinational firm to determine both the leverage and ownership structure in affiliates endogenously. A main finding is that affiliates with minority owners have less debt than wholly owned affiliates and therefore a less tax-efficient financing structure. This is due to an externality that arises endogenously in our model, where costs and benefits of debt shifting are shared asymmetrically between minority and majority owners. Our findings provide a theory framework for recent empirical findings.     

Stock-bond decoupling before and after the 2008 crisis

In this article, we analyse the co-movements of daily stock prices and government bond prices during the last 25 years, in major Western stock markets, extending previous results to take into account the impact of the current crisis. Our results confirm that bonds are viewed as instruments for improving portfolio diversification in periods of high volatility and falling stock market levels, which is when such diversification is most needed. The possibility of using government debt in portfolios as a means of hedging during times of financial crisis became especially apparent in the crises of 1997, 2001 and 2008. Nevertheless, during the current one, this diversification quality of bonds has disappeared in countries like Italy or Spain, which are also affected by sovereign debt issues.     

US Exports of Knowledge-intensive Services and Importing-country Characteristics

This paper studies the determinants of US exports of knowledge‐intensive services. Using US export data to as many as 29 countries between 1989 and 2002, I find the following. First, gross product and per capita income have heterogeneous effects on affiliated and non‐affiliated exports of knowledge‐intensive services. Secondly, property rights protection matters. Thirdly, infrastructure quality and political institutions only matter in the transfer of knowledge assets. Finally, financial depth is only correlated with the export of services to non‐affiliates.     

Dynamic Correlation Analysis of Asian Stock Markets

This paper examines the stock market linkages within the Asia-Pacific region and between Asian markets and the U.S. market over the period of January 2000 to June 2010, employing the dynamic conditional correlation GARCH model. Our results show that there exist very high correlations among the stock markets during the 2008 financial crisis. Therefore, consistent with the finding in literature, there are no diversification benefits during the financial crisis. However, our results show that there are still substantial opportunities for global investors to improve the risk-return performance between China and other markets during the sample period. In addition, we find evidence that the U.S. market significantly affects the stock markets in the Asia-Pacific region. Using T-GARCH model, there is a strong evidence of an asymmetric effect on conditional variance except stock markets in China and Malaysia.     

Does the market care about investor protection practices in China?

This study develops a scorecard with which to measure the investor protection practices of major listed firms in China during 2007–2010. We use time-series data to examine the relationship between the change in firm investor protection practices and market performance. Our results show that firms exhibiting improvements in investor protection practices manifest a subsequent increase in buy-and-hold abnormal returns. The results further indicate that the changes in the sub-index have different effects on a firm’s future performance. Shareholder rights to be rewarded seem to have the most significant and positive effect on a firm’s future performance for both local and international investors. Moreover, international investors pay attention to their rights to information. Our results provide evidence in support of the notion that the market does care about firm’s investor protection practices. The findings are robust to other measures of firm performance.     

Multidimensional financial development,exporter behavior and export diversification

Financial development shapes export sector performance because exporters need external finance and face credit constraints. Previous empirical research has relied largely on single-country studies. The Exporter Dynamics Database (EDD), which features firm-level exports from over 60 countries, reveals differences in the microstructure of the export sector across countries. In this paper, we first provide new evidence that these differences are related to cross-country variation in financial development and structure. Second, we combine the EDD and multidimensional data on financial development with a global database on export diversification. This study is the first to examine how macrolevel export diversification is determined by the microcharacteristics of the export sector. This approach is novel in the empirical literature on export diversification. According to our cross-country analysis, access to domestic financial services positively contributes to export diversification by increasing the number of small exporters, as financial services ease the credit constraints these exporters face.
