Investment allocation decisions,home bias and the mandatory IFRS adoption

We examine the familiarity hypothesis of home bias by studying how foreign ownership of Swedish firms is affected by the mandatory adoption of IFRS. We decompose foreign investors into institutional and non-institutional investors. Foreign investors are further decomposed into EU (IFRS adopting countries) and non-EU residents (non-IFRS adopting countries). We analyse the equity investments of these foreign investor groups in Sweden during the period of 2001–2007. We find that after the mandatory adoption of IFRS, foreign ownership/owners from countries that adopted IFRS and particularly those from the EU increased. These effects are particularly strong in small firms. Foreign institutional investors increased their ownership stake after the mandatory IFRS adoption, whereas foreign non-institutional investments were not affected significantly by the IFRS adoption. In contrast to ownership from non-adopting countries, ownership from the EU increased in firms with both more and less tangible assets. Similarly, foreign ownership from the EU increased in firms with both concentrated ownership and dispersed ownership after the adoption. Because Sweden has already had strict legal enforcement and a low level of earnings management prior to the adoption, our results suggest that increased foreign ownership is due to better abilities to compare firms rather than an improved quality.     

International portfolio diversification and the home bias puzzle

We review the literature on equity home bias, a phenomenon stating that investors do not hold enough foreign equities for an optimally diversified portfolio. We begin by defining the home bias measurement and reviewing related evidence on the bias. Further, we consider four explanations for this puzzling phenomenon: barriers to foreign investment, country-specific risks, information asymmetry, and cultural and behavioral factors. We analyze the related theoretical arguments and empirical findings of prior studies within each explanation. Based on the discussion of previous studies, several avenues for future research are suggested. (JEL G11, G15, F41)     

Loss aversion,asymmetric market comovements,and the home bias

Loss aversion has been used to explain why a high equity premium might be consistent with plausible levels of risk aversion. The intuition is that the first-order-different utility impact of wealth gains and losses leads loss-averse investors to behave similarly to investors with high risk aversion. But if so, should those agents not perceive larger gains from international diversification than standard expected-utility investors with plausible levels of risk aversion? They might not, because comovements in international stock markets are asymmetric: correlations are higher in market downturns than in upturns. This asymmetry dampens the gains from diversification relatively more for loss-averse investors. We analyze the portfolio problem of such an investor who has to choose between home and foreign equities in the presence of asymmetric comovement in returns. Perhaps surprisingly, in the context of the home bias puzzle we find that loss-averse investors behave similarly to those with standard expected-utility preferences and plausible levels of risk aversion. We argue that preference specifications that appear to perform well with respect to the equity premium puzzle should be subjected to this “test”.     

Cultural influences on home bias and international diversification by institutional investors

We investigate determinants of international diversification in institutionally managed portfolios from more than 60 countries. Survey-based country-specific variables on cross-cultural behaviors help to explain both home bias and diversification among foreign equities. In particular, investment funds from countries characterized by higher uncertainty avoidance behavior display greater home bias and are less diversified in their foreign holdings. Portfolios from countries with higher levels of masculinity and long-term orientation display lower levels of home bias, and portfolios from countries with higher levels of masculinity are more diversified abroad. Portfolios from culturally distant countries invest less abroad and underweight culturally distant target markets. The economic significance of cultural variables is high and comparable in magnitude to geographical distance, a consistent influence on foreign diversification in prior studies. Culture impacts investor behavior directly and not merely though indirect channels such as legal and regulatory framework.     

Immigration and equity home bias

Why do investors hold such large positions in domestic equity when there are gains to be made from international diversification? This equity home bias puzzle has received considerable attention in the literature, with asymmetric information on domestic and foreign assets (whether by individual choice or by market imperfection) emerging as the most plausible explanation. What happens when we consider a subset of investors whose information sets are closer to investors in foreign countries? I assess the relationship between immigration and equity home bias and find that inward migration is positively correlated with increased foreign equity positions and reduced home bias. Looking across income groups, outward migration reduces home bias for relatively rich countries, but may actually increase home bias when migration occurs to or from a developing country. These results suggest that immigration generates a positive externality of increased information flows for developed countries, but not for developing nations. The effects of immigration on investment are strongest within the Euro-Zone, suggesting that this positive externality of immigration is largest when barriers to portfolio diversification (such as currency risk) are lowest.     

IFRS adoption in China and foreign institutional investments

We examine the effectiveness of China’s IFRS adoption from the perspective of an important set of financial report users, foreign institutional investors. We find that foreign institutional investment does not increase after China’s IFRS adoption, and some evidence that it actually declines, particularly among firms with weaker incentives to credibly implement IFRS, or with greater ability to manipulate IFRS’s fair value provisions. We also find that the association between earnings and returns generally declines after IFRS adoption, consistent with reduced earnings quality. In addition, we find that foreign institutional investors’ returns decrease after China’s IFRS adoption. Finally, the decline in foreign institutional investment is greater among investors from countries with weak institutions that have also adopted IFRS. Taken together, our evidence suggests that the weak institutional infrastructure in China’s transitional economy impairs IFRS’s intended goal of attracting institutional investment through improved financial reporting quality. Further, financial information users’ home country institutions and IFRS adoption experience affect the effectiveness of IFRS adoption.     

The home-institution bias

We document a new investor preference we call the home-institution bias. Whereas the home-asset bias is a preference for domestic assets, the home-institution bias is a preference for domestic financial institutions. Our data come from Sweden’s government-mandated retirement system. In cross-fund regressions, we find that funds offered by Swedish institutions received around 10 times more money than similar funds offered by foreign institutions. We show that this preference for home institutions is distinct from the home-asset preference, is not driven by information asymmetries, and is consistent with an underlying preference by individuals to deal with the familiar. Cross-individual regressions also support a behavioral explanation because the home-institution bias is strongest among financially-unsophisticated and provincial investors.     

IFRS and the regulatory environment: The case of U.S. investor allocation choice

This paper investigates whether a country’s use of international financial reporting standards (IFRS) is associated with increased US investment in foreign equities. The recent global trend towards the use of IFRS may signal attempts by policy makers to reduce information asymmetries for international investors. However, a concern is that these standards must be accompanied by a stronger regulatory environment in order for them to gain legitimacy. Investor allocation choice is based on US holdings of foreign equities and the regulatory environment is interpreted using two distinct factors: the legal standards system and the enforcement regime. We document that US investment is associated with IFRS only when it is combined with a strong regulatory environment, specifically a strong enforcement regime. We also find that mandating IFRS is attractive to US investors only when combined with a strong regulatory environment.     

The impact of XBRL adoption on local bias: Evidence from mandated U.S. filers

This paper investigates how eXtensible Business Reporting Language (XBRL) adoption affects the information advantage of local investors relative to their non-local counterparts. By employing the recent staggered SEC mandates of XBRL as a natural shock, we show that institutional investors’ local bias decreases after firms adopt XBRL when preparing their financial statements. These results hold in a difference-in-difference research design with firm and year fixed effects or using matched nonadopting firms as controls, as well as a regression discontinuity design. The impact of XBRL adoption on reducing local bias can be explained by three economic channels: decreased information processing costs, increased corporate disclosures, and improved analyst coverage. We further find that institutions’ superior stock returns in geographic proximate equity investments significantly reduces after the XBRL mandate. The observed reduction in institutional investors’ local bias within U.S. companies following the XBRL mandate also applies to the international setting. Overall, our findings support regulators’ claim that XBRL adoption levels the playing field between local and non-local investors.     

Foreign exposure through domestic equities

We show that US investors obtain substantial foreign exposure through their holdings of domestic equities. Domestic multinationals, in particular, provide significant foreign exposure. We also find that, although the average US investor is less tilted toward domestic multinationals, institutional investors do overweight domestic firms that are more internationally oriented. ‘Indirect’ foreign holdings through domestic multinationals are shown to be substantial; combining them with reported data on international positions almost doubles US investors’ total ‘foreign’ holdings. Our findings indicate that the home bias is not as severe as assessments based on reported international investment statistics suggest.     

Equity home bias and corporate disclosure

I show that more comprehensive corporate disclosure reduces investors’ uncertainty about domestic companies’ payoffs at no cost, thereby decreasing investors’ equity home bias toward a country. Since investors should base their investment decisions on valid and easily interpretable company information only, more comprehensive disclosure will reduce the home bias only if domestic securities law is sufficiently stratified and domestic companies use international accounting standards. Using panel data for 38 countries from 2003 to 2008 I find that more comprehensive disclosure reduces investors’ home bias, though significantly only for countries that sufficiently enforce their securities law and implement international accounting standards.     

The world price of home bias

Theoretical arguments suggest that as the degree of a country's home bias increases, the global risk sharing between domestic and foreign investors will reduce and thereby increase the country's cost of capital. Consistent with this prediction, we find international differences in the cost of capital to be strongly and positively related to varying degrees of home bias for 38 markets. This finding is robust to different cost of capital proxies, different control variables, alternative home-bias measures, international tradability of stocks, and alternative specifications. Therefore, the overall evidence implies that countries may enjoy a significantly lower cost of capital by reducing the extent of their home bias and hence, increasing global risk sharing.     

Does mandatory IFRS adoption improve information quality in low investor protection countries?

We examine the effect of mandatory IFRS adoption on the information quality of financial reporting in France, Germany and Sweden. These three Western European civil law countries are characterized as low investor protection by the World Economic Forum's 2012/2013 Global Competitiveness Report. Using data for 2003 and 2011, we find significant improvement in both forecast accuracy and forecast dispersion following mandatory IFRS adoption in all three countries. Furthermore, the effect on information quality is greater the lower the strength of investor protection. These results suggest that mandatory IFRS adoption in low investor protection countries leads to an improvement in information quality. A tentative implication of the results is that standard setters should not delay IFRS adoption pending regulators implementing a high investor protection.     

Home sweet home: Home bias and international diversification among individual investors

A striking feature of international portfolio investment is the extent to which equity portfolios are concentrated in the domestic market of the investor. We investigate differences in home bias on an individual level by studying portfolios formed as a part of the new defined contribution pension plan in Sweden. We estimate the likelihood of home bias and use individuals’ demographic and socioeconomic features as explanatory variables. Our findings indicate that the likelihood of home bias is caused by both rational and irrational factors. Moreover, we relate home bias to investors’ desire to hedge against inflation, sophistication and overconfidence.     

Dividend Payouts and Information Shocks

We examine changes in firms’ dividend payouts following an exogenous shock to the information asymmetry problem between managers and investors. Agency theories predict a decrease in dividend payments to the extent that improved public information lowers managers’ need to convey their commitment to avoid overinvestment via costly dividend payouts. Conversely, dividends could increase if minority investors are in a better position to extract cash dividends. We test these predictions by analyzing the dividend payment behavior of a global sample of firms around the mandatory adoption of IFRS and the initial enforcement of new insider trading laws. Both events serve as proxies for a general improvement of the information environment and, hence, the corporate governance structure in the economy. We find that, following the two events, firms are less likely to pay (increase) dividends, but more likely to cut (stop) such payments. The changes occur around the time of the informational shock, and only in countries and for firms subject to the regulatory change. They are more pronounced when the inherent agency issues or the informational shocks are stronger. We further find that the information content of dividends decreases after the events. The results highlight the importance of the agency costs of free cash flows (and changes therein) for shaping firms’ payout policies.     

Do Improvements in the Information Environment Enhance Insiders’ Ability to Learn from Outsiders?

We examine whether and how an exogenous shock to the information environment changes insiders’ ability to learn from outsiders. We document three main findings. First, we find an increase in investment‐to‐price sensitivity following the adoption of International Financial Reporting Standards (IFRS). Second, we show that the relation between the market reaction to M&A deal announcements and the likelihood of deal completion becomes stronger after IFRS adoption. Third, we find significant improvements in post‐acquisition operating and stock return performance post‐IFRS adoption. These results are more pronounced for firms that experienced significant increases in foreign institutional ownership around IFRS adoption, especially when these foreign investors are from countries that matter for the firm’s growth opportunities. Taken together, our findings suggest that insiders’ ability to learn from outsiders improves post‐IFRS, and this improved ability to learn from outsiders leads to real economic gains.     

Home bias in portfolio choices: social learning among partially informed agents

Using an ‘incomplete information’ model, we explore the role of social learning in the global portfolio choices of stock market investors. When partially informed followers attempt to estimate true domestic (home) mean returns, they likely acquire private domestic signals from partially informed leaders. However, the calibration results indicate the existence of home bias when partially informed agents have poor quality information. Partially informed agents are prone to a learning bias; they overreact to new domestic information due to overconfidence in their domestic private signals, but they demonstrate a conservative response to new information in foreign markets. Links between the private signals of partially informed agents may lead to correlated foreign investment strategies among such agents through social learning. We suggest the acquisition of private signals, along with the dissemination of information, affect international portfolio decision rules and are determinants of the phenomenon of home bias.     

IPOs and IFRS in European exchange-regulated markets: A research note

This research note aims to enrich our understanding of reporting incentives of firms listed in European exchange-regulated markets. Many initial public offerings (IPOs) in Europe are within exchange-regulated markets where firms are allowed to choose between local GAAP and IFRS. Therefore, this research note describes the regulatory environment and investigates the choice to voluntarily adopt IFRS within European exchange-regulated markets. Overall, less than 20% of the firms voluntarily adopt IFRS and voluntary IFRS adoption upon IPO is positively associated with firm size, foreign firms, stocks offered to institutional investors prior to the IPO, and a future migration to an EU-regulated market.

Information Immobility and the Home Bias Puzzle

Many argue that home bias arises because home investors can predict home asset payoffs more accurately than foreigners can. But why does global information access not eliminate this asymmetry? We model investors, endowed with a small home information advantage, who choose what information to learn before they invest. Surprisingly, even when home investors can learn what foreigners know, they choose not to: Investors profit more from knowing information others do not know. Learning amplifies information asymmetry. The model matches patterns of local and industry bias, foreign investments, portfolio outperformance, and asset prices. Finally, we propose new avenues for empirical research.
