    Do markets penalize agency conflicts between controlling and minority shareholders? Evidence from Chile
    (BLACKWELL PUBLISHING, 2007) Lefort, Fernando; Walker, Eduardo
    Using a sample of Chilean listed firms with widespread presence of economic conglomerates that use pyramid structures to control affiliated companies, we find that firms where controlling shareholders have higher coincidence between cash and control rights are persistently more valued by the market. We carefully check that our results are not driven by omitted variable biases and control for reverse causation using a feature of Chilean Corporations Law that provides an exogenous instrument for ownership concentration.

    Investment performance, regulation and incentives: the case of Chilean pension funds
    (2021) Lopez, Fernando; Walker, Eduardo
    We examine the investment performance of Chilean pension funds during their multi-fund period (2003-17). Using tradable asset class benchmarks, we extend Sharpe's (1992) return-based style analysis by explicitly considering regulatory restrictions and currency hedging. We find that despite the significant differences between pension fund manager returns, they are statistically similar to our style benchmarks for all fund types. Furthermore, accounting for currency hedging improves the accuracy of the replicating portfolios and the selection return estimates. Our results have policy implications for investment regulation of pension systems with similar characteristics to the Chilean one.

    Optimal close-to-home biases in asset allocation
    (ELSEVIER SCIENCE INC, 2011) Varas, Felipe; Walker, Eduardo
    This article studies optimal portfolio decisions with (long-term) liabilities for small open economy based investors, including the optimality of currency hedging (Walker (2008a). Chile is the home country of the representative investor, but results are likely to hold more generally. The problem is set up as in Sharpe and Tint (1990) and Hoevenaars, Molenaar, Schotman and Steenkamp (2007). Hedging the liabilities and the consumption currency may imply optimal close-to-home biases, defined as overweighting asset classes which are highly correlated with local ones. The implementation challenges include: developing a methodology to estimate expected returns in local (real) currency; estimating the covariance matrix allowing for serial and crossed-serial correlations; and checking the results' robustness using a resampling method. The findings are: (i) portfolios always have optimal close-to-home biases, beyond the investment in local fixed income to hedge liabilities; (ii) currency hedging reduces investment in close-to-home asset classes, (iii) but has ambiguous effects on welfare detected with the resampling method; (iv) currency hedged long-term US bonds are useful for hedging local interest rate risk; and (v) liabilities give access to high risk-return portfolios, not affecting otherwise the overall shape of the efficient regions. This article can be useful to investors based on small open economies, including pension funds, insurance companies, sovereign wealth funds and Central Banks. (C) 2009 Published by Elsevier Inc.

    Strategic currency hedging and global portfolio investments upside down
    (2008) Walker, Eduardo
    The literature on the convenience of currency hedging of international portfolio investments has not reached a final verdict. There are arguments for (Perold and Schulman [Perold, A.F. and Schulman, E.C. (1988). The free lunch in currency hedging: implications for investment policy and performance standards, Financial Analysts Journal, May/June Vol. 44, No. 3: 45-52]) and against (Froot [Froot, K. (1993). Currency hedging over long horizons. NBER Working Paper 4355.] and Campbell et al. [Campbell, J.Y., Viceira, L.M. and White, J.S. (2003). Foreign currency for long-term investors. The Economic Journal, Volume 113, Number 486, (March), pp. C1-C25(1)]). This paper analyzes the perspective of global investors based in emerging markets, for which hedging should imply increasing expected returns. The question thus is whether currency hedging is a "free lunch" in this case. No free lunch exists, as it turns out. Hard currencies act as natural hedges against global (and local) portfolio losses, since they tend to appreciate with respect to emerging market currencies when the world portfolio return is negative. Therefore, in this case currency hedging increases volatility-although also increasing expected returns. This result is likely to hold generally for relatively open economies with flexible exchange rate regimes. (C) 2007 Published by Elsevier Inc.
