2 Introduction What Makes International Finance Different? Deviations From PPP Barriers to Investment Implications Domestic CAPM Does Not Hold Separation Theorems Do Not Hold FEX Risk and Market Integration Key Concepts

3 International Asset pricing Models

4 Under perfect financial markets, and identical consumption opportunity sets, an investor can achieve same expected lifetime utility regardless of residence. However, PPP deviations are significant and suggest the heterogeneity of national consumption tastes as a foundation for international finance. Solnik (1974) asset pricing model where exchange risk is priced. The risk premium of a security over its national risk free rate is proportional to the risk premium of the world market over an average international bond rate.

5 Adler and Dumas (1983) Investors will attempt to hedge against inflation. The optimal portfolio is the combination of - Portfolio of a logarithmic investor which is the same for all investors, and a investor specific portfolio that provides best possible hedge against inflation. Stulz (1981) The consumption baskets may differ across investors, investment opportunity set can change over time The expected excess real return of a risky asset is proportional to the covariance of the home currency return of that asset with changes in world real consumption rate.

6 Is FEX Risk Priced? Dumas & Solnik (1995) The hypothesis of zero price on exchange rate risk for conditional IAPM is rejected DeSantis & Gerrard (1998) Components of the risk premiums vary significantly over time and across markets. The average premium for currency risk appears to be only a small fraction of the sum of market and currency premiums. Karolyi & Stulz (2002) In equilibrium, in a symmetric world where consumption opportunity sets differ across countries, exposures to foreign exchange rates will be priced in stocks.

7 Models of perfect international financial markets have severe limitations. -An asset whose excess return has a zero covariance with the return on world market portfolio, does not seem to have an expected excess return equal to zero. -The home bias puzzle and the high volatility of equity flows is inconsistent with models where investors have the same information across countries and where financial markets are assumed to be perfect. Although, global financial markets have become more open to foreign investors, barriers remain. Models that do not take into account barriers are suspect.

8 Tax proportional to the absolute value of domestic investors’ holdings of risky foreign assets. Barriers decrease trade in assets that do not provide expected return large enough to offset the cost of barriers. E(R) on foreign assets is higher than implied by CI The world portfolio of stocks can not be efficient for any investor. Adding foreign assets to a portfolio of domestic assets is not necessarily a good thing. Stulz (1981)

9 Errunza and Losq (1985) Limiting case of Stulz (1981). Unequal access assumption. Yields a closed-form solution for the equilibrium Risk- Return trade-off Lends to the analysis of a continuum of market structures Freely traded securities are priced as if the market was not segmented -- only global risk premium Ineligible securities command a super risk premium which is conditional on the availability of substitute assets. With perfect substitutes in the world market, super risk premium vanishes.

10 MILD SEGMENTATION Limiting Case of Stulz (1981) Yields a closed-form solution for the equilibrium Risk-Return trade-off Freely Traded E I E IV E II E III Lends itself to analysis of a continuum of market structures

11 Are Markets Integrated, Segmented or Mildly Segmented ! Markets fall somewhere in between CS & CI Major markets largely integrated EMs mildly segmented - Local risk most relevant Cross-listings have played an important integrating role even under the presence of barriers Impropriety of using RAW correlations of marketwide index returns as a measure of market integration. Financial market development and removal of barriers to foreign portfolio investment play a role in integrating EMs

12 The Estimated Integration Index- MEXICO CF-6/81, Liber Source: Carrieri, Errunza and Hogan (2002)

13 Where do we go in Asset Pricing! To-date, the conditional tests of FEX premia and market integration have been based on unconditional IAPMs eventhough an intertemporal IAPM is called for. The intertemporal IAPM of Chang, Errunza, Hogan & Hung (2002) prices market hedging risk and exchange rate hedging risk in addition to market risk and exchange rate risk. However, much remains.

14 Other Factors

15 Fama-French Factors Fama-French (1998) :Size, Book to Market, PE, Divd. Yield - different pricing across EMs – Weak results Griffin (2001): Country specific F-F factors better explain time series variation in international stock returns Serra (2000): Weak results for Attributes and Liquidity Need further research

16 Corporate Governance La Porta, Lopez-De-Silanes, Shleifer and Vishny (1997) show that countries with poor legal environment, measured by rules and quality of enforcement have smaller and narrower capital markets. Bhattacharya & Daouk (2002) C.O.C. does not change after the introduction of insider trading laws, but decreases significantly after the first prosecution. Lang, Lins & Miller (2002) Cross-listed firms have greater analyst coverage, and higher valuations from improved information environment

17 Corporate Governance (Contd.) Stulz and Williamson (2001) country’s principal religion helps predict the cross-sectional variation in creditor rights better than a country’s openness to international trade, its language, its income per capita, or the origin of its legal system. Dyck & Zingales (2002) minority shareholder protection, enforcement of laws and extra-legal protections are associated with lower control premium. We have just begun to understand the relation between development, governance and performance.

18 Impact of Market liberalization Results are consistent with predictions of IAPMs The cost of equity capital decreases around liberalization. Firm level results of Errunza & Miller (2000), are consistent with market level studies of Bekaert & Harvey (2000), Henry (2000) The decline in the cost of capital is driven by the pre- announcement diversification potential of the foreign firm Theoretical and empirical results for the impact of introduction of CFs support C.O.C. hypothesis Analyze liberalization impact at sector/firm level.

19 International Diversification

20 Should We Diversify Internationally? DeSantis & Gerard (1997) On average, the expected gains from international diversification are equal to 2.11 percent on an annual basis Errunza, Hogan & Hung (1999) Index level correlations overstate the gains from investing in securities that only trade abroad. Gains beyond those attainable through home-made diversification are statistically and economically insignificant. Investors no longer need to trade abroad to achieve an internationally mean-variance efficient portfolio.

21 Equity Home Bias Lewis (1999): Hedging home risk with home equity & Diversification costs that exceed the gains Stulz, Dahlquist, Pinkowitz & Williamson (2002) Prevalence of closely held firms in countries with poor investor protection explains part of U.S. home bias What about U.S. studies! Coval and Moskowitz (1999): Geographic bias of U.S. investors Grinblatt and Keloharju (1999): Household portfolios are concentrated and are under-diversified Further studies are called for

22 Industrial Structure & Diversification Roll (1992), Arshanapalli, Doukas and Lang (1997) : Industry factors are important Heston and Rouwenhorst (1994), Griffin and Karolyi (1998) : Industry factors are not important Griffin and Stulz (2001):Industries which produce internationally traded goods may have a sizable exposure to industry-specific shocks. Carrieri, Errunza & Sarkissian (2002) : The global industry risk is priced for certain industries. Gains are larger with industry-specific global diversification

23 Corporate International Diversification Errunza & Senbet (1981): MNCs provide a vehicle for international portfolio diversification which in equilibrium results in a price premium for the MNC. Further, there exists a systematic positive relationship between current degree of international involvement and excess market value. Bodnar, Tang & Weintrop (1997): Report positive effect of corporate international diversification on firm value and a significant international diversification premium. Denis, Denis & Yost (2001): Report significant diversification discounts for both single-segment and multiple-segment MNCs. Need to resolve the differences based on THEORY and new EMPIRICS

24 MORE EMPIRICAL THAN THEORETICAL Difficult to model complex nature of World market Need simplifying assumptions Aggregation problem unresolved Capturing realism, tractability, intuitive clarity, testability Difficult to publish theory in top journals If you can do it you will be famous.

25 Empirics have barely scratched the surface Solnik and Adler-Dumas variants for DMs Errunza-Losq variants for EMs Most work related to investments New data set availability - DMs & EMs Conditional Tests Very little work on Corp. Finance
