Time-varying international diversification and the forward premium

This paper reproduces the slope of the uncovered interest rate parity (UIP) regression for ten country pairs within one standard deviation under rational expectations. We propose an infinite horizon dynamic stochastic general equilibrium model with incomplete markets. Heterogeneous investors experience varying risk aversion as a result of habit formation.The underlying mechanism of the model relies on varying international diversification in the investors' portfolio choice decision. In response to their changing habit levels, investors' hedging desire varies over time. This leads to adjustments in interest rates. The habit-induced investment decisions are negatively correlated with movements in the exchange rate. This results in a negative correlation between interest rates and expected exchange rates, as implied by a negative UIP slope.Depending on the magnitude of habits, the model is capable of reproducing positive as well as negative UIP slopes, as seen empirically in the data.     

The effects of the Asian crisis, corporate governance and accounting system on the valuation of book value and earnings

This paper examines the value relevance of earnings and book value in four Asian countries, Indonesia, South Korea, Malaysia and Thailand, in the period surrounding the Asian financial crisis. Specifically, we examine the impact of the economic environment on the value relevance of book value and earnings. We also examine the effects of corporate-governance mechanisms and the type of accounting system together with the economic environment on the value relevance of accounting numbers. Our results indicate that the value relevance of earnings in Indonesia and Thailand was significantly reduced during the Asian financial crisis while the value relevance of book value increased. In Malaysia, the value relevance of both earnings and book value decreased during the crisis. In Korea, neither book value nor earnings was significantly impacted by the crisis. Our results indicate that the level of corporate-governance mechanisms has an impact on the extent of changes in the value relevance of book values, but not earnings. Specifically, the value relevance of book value declines when corporate governance is weak. Finally, our results indicate that accounting systems (i.e., IAS or tax-based) also affect the extent of changes in the value relevance of book value resulting from the crisis.     

Market segmentation and international diversification across country and industry portfolios

We conjecture that partially segmented stock indexes that are characterized by low correlation with the world market are mainly priced by local factors and should produce abnormal returns relative to a global asset-pricing model. This implies a negative relation between correlation and future index returns in the presence of segmented indexes. Empirical evidence confirms such a relationship for the sample of industry indexes, suggesting a heterogeneous segmentation. However, we do not observe a similar pattern for country indexes. In addition, the international diversification potential of industries does not vanish during volatile periods. The hypothesis that the negative relationship should be stronger for the more segmented subsamples that are characterized by small market size and emerging country origin is verified for the industry sample. Thus, cross-industry diversification is superior to mere cross-country diversification.     

Exploring the benefits of international government bond portfolio diversification strategies

We use the Bayesian approach of Wang (1998) to examine the diversification benefits of investing in international government bonds. We find that no short-selling constraints substantially reduce but do not eliminate the diversification benefits when only investing in G7 government bonds with different maturities. There are significant diversification benefits when using the G7 bonds, an inflation-linked bond index, and emerging market bonds even in the presence of no short-selling constraints. The superior performance is driven by the emerging markets bonds. We also find that the diversification benefits vary across different economic states.     

An empirical examination of the benefits of international diversification

We examine the benefits of international portfolio diversification for U.K. investors between January 1985 and December 2000 using the approach of Wang [Wang, Z., 1998. Efficiency loss and constraints on portfolio holdings. Journal of Financial Economics 48, 359–375] and Li et al. [Li, K., Sarkar, A., Wang, Z., 2003. Diversification benefits of emerging markets subject to portfolio constraints. Journal of Empirical Finance 10, 57–80]. We find significant increases in the Sharpe [Sharpe, W.F., 1966. Mutual fund performance. Journal of Business 39, 119–138] and certainty equivalent return (CER) performance in moving from a domestic strategy to an international strategy that includes either global industry or country equity portfolios, even in the presence of short selling restrictions. We also find significant diversification benefits using U.K. unit trusts with international equity objectives. However, U.K. international unit trusts do not capture all the diversification benefits provided by either global industry or country equity portfolios.     

The effect of corporate diversification on credit risk: new evidence from European credit default swap spreads

This article investigates the impact of corporate diversification on credit risk. To our best knowledge, this is the first paper to use credit default swap (CDS) spreads instead of bond yield or revalued book values to test the risk‐reduction hypothesis. The analysis relies upon a sample of STOXX^® EUROPE 600 index members and covers the years 2010–2014. After controlling for various CDS‐ and firm‐specific variables, we find that diversification strategies do not significantly lower CDS premiums. Multilevel mediation analysis further shows that information asymmetries overcompensate the risk‐reducing effects resulting from corporate diversification.     

Sources of gains from international portfolio diversification

This paper looks at the determinants of country and industry specific factors in international portfolio returns using a sample of forty eight countries and thirty nine industries over the last three decades. Country factors have remained relatively stable over the sample period while industry factors have significantly increased during the last decade and dropped again since 2000. The importance of industry and country factors is correlated with measures of economic and financial international integration and development. We find that financial market globalization is the main driving force behind the changes in relative magnitude of the different shocks. Country factors are smaller for countries integrated in world financial markets and have declined as the degree of financial integration and the number of countries pursuing financial liberalization has increased. Higher international financial integration within an industry increases the importance of industry factors in explaining returns. Economic integration of production also helps in explaining returns. Countries with a more specialized production activity have higher country shocks.     

International diversification and Microfinance

International commercial banks, institutional investors, and private investors have become increasingly interested in financing microfinance institutions (MFIs). This paper investigates whether adding microfinance funds to a portfolio of risky international assets yields diversification gains. By using mean-variance spanning tests with short-sale constraints, we find that investing in microfinance may be attractive for investors seeking a better risk-return profile. Specifically, the analysis suggests that investing in MFIs from Latin America, or microfinance and rural banks yields more efficient portfolios. In contrast, adding MFIs from Africa or microfinance NGOs to a portfolio of international assets is not beneficial for a mean-variance investor.     

Firm diversification and earnings management: evidence from seasoned equity offerings

Popular press suggests that diversified firms are more aggressive in managing earnings than non-diversified firms. We examine this claim in the seasoned equity offering (SEO) setting, where firms have been shown to have the incentive to manage earnings upwards. Using the cross-sectional modified Jones [(1991) J Accounting Res 29:193–228] model to measure discretionary current accruals, we find that discretionary current accruals are higher among diversified firms than in non-diversified ones. Our evidence is consistent with the view that the extent of firm diversification is directly related to the degree of earnings management. We further show that diversified issuers with high discretionary accruals underperformed other SEO firms.

Valuation effects of corporate social responsibility

This paper develops a valuation model of the firm that provides for the expenditure of corporate resources in support of community, social or environmental causes. We show that under certain circumstances CSR expenditures create value for the firm. We also test our model by simulations and confirm that, at least under some conditions, CSR does pay off in the form of value creation.     

Debt,diversification and earnings management

In this article we use panel-estimation techniques to calculate discretionary accruals (DAC) and to produce a better understanding of the nature of the relation between debt and earnings management. Consistent with the transparency hypothesis (which suggests that diversification increases the complexity of firms’ activities and reduces their transparency to outsiders), we find that for less-diversified (more transparent) firms, debt reduces positive discretionary accruals, whereas in relatively more-diversified (less transparent) firms the impact of debt becomes positive. Our paper shows that marginal increases in debt provide the incentives for managers to manipulate earnings, and diversification provides the needed context for this accounting practice to be possible. We have also found that only in the sub-sample of aggressive firms, those that manage discretionary accruals with enough magnitude to increase income, do lenders exert their control. Some firms, however, take advantage of diversification to avoid this control. Our findings are robust to several earnings-management measures and methodologies.     

International portfolio diversification: a synthesis and an update

This paper provides a synthesis of the existing literature on international portfolio diversification and presents some new results on the subject. We address the question of whether international portfolio diversification is always a reasonable method of reducing the risk of an investment portfolio without negatively affecting its return expectations. Unfortunately, there is still not a simple answer to this question. When ex-post data is examined, potential benefits of international diversification can certainly be detected. However, we also argue that it might be difficult for investors to select an optimal investment strategy ex-ante, when the correlation structure among the international equity is unstable over time. While such findings do not completely rule out the potential benefits of international diversification, they certainly make them more difficult to realize in practice.     

Effects of law on corporate financing practices—international evidence from convertible bond issues

Firms can adjust their convertibles to be more debt-like or equity-like through several contract terms. In particular, by providing call protection, a convertible issuer can assure its convertible bondholders that it will not force them to become equity holders during the call protection period. The possibility of a forced conversion instituted by an early call should be more threatening to investors in an economy where local laws are biased against shareholders. I examine call protection terms in an international sample and find evidence consistent with the hypothesis that convertible bond design varies based on the features of local law.     

Firm diversification and the value of corporate cash holdings

This paper studies the effect of firm diversification on the value of corporate cash holdings. We develop two hypotheses based on efficient internal capital market and agency problems. We find that the value of cash is lower in diversified firms than in single-segment firms, and that firm diversification is associated with a lower value of cash in both financially unconstrained and constrained firms. We find that firm diversification has a negative (zero) impact on the value of cash among firms with a lower (higher) level of corporate governance. These findings are consistent with the interpretation that firm diversification reduces the value of corporate cash holdings through agency problems.     

Impact of corporate governance and related controversies on the market value of banks

Effective corporate governance of financial institutions, particularly in the banking sector, is vital for the stability of the financial system and the prevention of financial crises. Thus, this study examines the impact of corporate governance and related controversies on the market value of banks. For this purpose, we utilized Refinitiv’s corporate governance scores, including management, shareholder value, and corporate social responsibility (CSR), as well as its corporate governance controversies scores to analyze their impact on the market value of 242 banks in 43 countries. Using Refinitiv’s ESG database from 2017 to 2021, we conducted a path analysis and found a positive and statistically significant relationship between the CSR strategy scores and the market value of banks as well as between the management scores and the market value of banks. Moreover, there is a statistically significant relationship between the corporate governance controversies scores and the market value of banks.     

Managerial incentives and corporate leverage: evidence from the United Kingdom

This paper investigates the effect of managerial incentives and corporate governance on capital structure using a large sample of UK firms during the period 1999–2004. The analysis revolves around the view that managerial incentives are important in determining a firm's leverage. However, we argue that the exact impact of these incentives on leverage is likely to be determined by firm‐specific governance characteristics. To conduct our investigation, we construct a simple corporate governance measure using detailed ownership and governance information. We present evidence of a significant non‐monotonic relationship between executive ownership and leverage. There is also strong evidence suggesting that corporate governance practices have a significant impact on leverage. More importantly, the results reveal that the nature of the relation between executive ownership and leverage depends on the firm's corporate governance structure.     

Diversification,corporate governance and firm value in small markets: evidence from New Zealand

We find that diversified firms in New Zealand are associated with a value discount of 19–42 per cent relative to single‐segment (undiversified) firms. Although several competing explanations have been offered in the literature, we find that the strength of corporate governance explains between 15–21 per cent of this discount. Specifically, board size, busyness of directors, CEO ownership and whether or not compensation of directors includes equity‐based components collectively explain a large part of the reported discount. Our results from companies trading in New Zealand complement recent findings in the US by not only confirming the existence of a diversification discount but also emphasizing the role of poor governance in destroying shareholder wealth by pursuing a value‐destroying corporate strategy. All our results hold after controlling for potential endogeneity in the decision to diversify and the choice of corporate governance structure by employing two‐way fixed‐effects and dynamic‐panel generalized method of moments regression techniques.     

Board gender composition and waste management: Cross-country evidence

Extant literature on board gender diversity focuses on the main pillars of sustainability while ignoring the important subdimension – waste management. Using a sample of 8365 firm-year observations for the period 2002–2017 from 37 countries, we provide novel empirical evidence that board gender diversity significantly reduces (increases) waste generation (waste recycling) in firms. We also note that the impact is significant with two or more female directors and is primarily driven by female directors’ independence. Moreover, the relationship is moderated by the masculinity dimension of national culture and sustainable compensation policies. Our analysis also shows that waste management activities of gender-diverse boards accompany the better financial performance. Our findings are robust to several identification strategies and estimation techniques. Our study provides new insights into the governance–sustainability nexus and presents important policy implications for regulators across countries.     

The implied cost of equity capital,corporate investment and chief executive officer turnover

This study investigates how the cost of equity capital, along with corporate investment, affects chief executive officer (CEO) turnover decisions. We hypothesize that the cost of equity conveys information about firm performance uncertainty that is informative of CEO talent. Consistently, our empirical results show that the likelihood of CEO turnover is positively associated with the implied cost of equity, after controlling for earnings and stock performance measures and risk factors. Additional analysis of reverse causality supports the causal effect of the high cost of equity on CEO dismissals. We also find that the positive association is more pronounced for firms that are more likely to suffer from underinvestment problems. These results suggest that the cost of equity plays a more important role in assessing CEO performance when the firm needs more external equity capital to pursue investment opportunities.     

Capital structure effects of international expansion

This study investigates and qualifies the impact of internationalization on the capital structure of a firm. Previous studies have associated firm internationalization with foreign sales or foreign assets. However, an increase in sales volume generated abroad does not necessarily mean that a firm has actually invested in a new foreign country. This study examines non-financial firms included in the main developed stock indexes that report a new geographical area of operation. It reveals that, at less advanced levels of internationalization, growth in foreign volumes and new geographic expansion lead to differential decision-making in capital structure choices.This study concludes that (1) when the target foreign market is developed, the new market entry does not lead to significant changes in capital structure, whatever the past experience of the firm. (2) The capital structure of well-diversified firms is not significantly modified following a new foreign entry. (3) Both domestic firms and firms only active in developed markets significantly increase their debt to equity ratio when expanding into a region or country where they had no operation before. Well-diversified firms clearly exhibit a different behavior compared to firms in less advanced levels of internationalization.
