Consumption, Dividends, and the Cross-Section of Equity Returns

We show that aggregate consumption risks embodied in cash flows can account for the puzzling differences in risk premia across book-to-market, momentum, and size-sorted portfolios. The dynamics of aggregate consumption and cash flow growth rates, modeled as a vector autoregression, are used to measure the consumption beta of discounted cash flows. Differences in these cash flow betas account for more than 60% of the cross-sectional variation in risk premia. The market price for risk in cash flows is highly significant. We argue that cash flow risk is important for interpreting differences in risk compensation across assets. Copyright 2005 by The American Finance Association.

Regulatory Pressure and Fire Sales in the Corporate Bond Market

This paper investigates fire sales of downgraded corporate bonds induced by regulatory constraints imposed on insurance companies. Regulations either prohibit or impose large capital requirements on the holdings of speculative-grade bonds. As insurance companies hold over one third of all outstanding investment-grade corporate bonds, the collective need to divest downgraded issues may be limited by a scarcity of counterparties and associated bargaining power. Using insurance company transaction data from 2001-2005, we find insurance companies that are relatively more constrained by regulation are, on average, more likely to sell downgraded bonds. This forced selling generates elevated selling pressure around the downgrade which causes price pressures and subsequent price reversals that are indicative of significant periods during which transaction prices deviate from fundamental values. Most importantly, bonds widely held by constrained insurance companies experience significantly larger price reversals. Investors providing liquidity to this market appear to earn abnormal returns.

What Segments Equity Markets

We propose a new, valuation-based measure of world equity market segmentation. While we observe decreased levels of segmentation in many developing countries, the level of segmentation is still significant. In contrast to previous research, we characterize the factors that account for variation in market segmentation both through time as well as across countries. While a countrys regulation with respect to foreign capital flows is important in determining its level of segmentation, we find that non-regulatory factors are also related to the cross-sectional and time-series variation in the level of segmentation. We identify a countrys political risk profile and its stock market development as two additional local segmentation factors as well as the U.S. corporate credit spread as a global segmentation factor.

Market Efficiency, Asset Returns, and the Size of the Risk Premium in Global Equity Markets

An important economic insight is that observed equity prices must equal the present value of the cash flows associated with the equity claim. An implication of this insight is that present values of cash flows must also quantitatively justify the observed volatility and cross-correlations of asset returns. In this paper, we show that parametric economic models for present values can indeed account for the observed high ex-post return volatility and cross-correlation observed across five major equity markets. We present evidence that cash flow growth rates contain a small predictable long-run component; this feature, in conjuction with time-varying systematic risk, can justify key empirical characteristics of observed equity prices. In many cases, our model can also capture observed equity price levels. Our evidence suggests that the ex-ante risk premium on the global market portfolio has dropped considerably - we show that this fall in the risk premium is related to a decline in the conditional variance of global real cash flow growth rates.

The European Union, the Euro, and equity market integration.

We use industry valuation differentials across European countries to study the impact of membership in the European Union as well as the Eurozone on both economic and financial integration. In integrated markets, discount rates and expected growth opportunities should be similar within one industry, irrespective of the country, implying narrowing valuation differentials as countries become more integrated. Our analysis of the 1990–2007 period shows that membership in the EU significantly lowered discount rate and expected earnings growth differentials across countries. In contrast, the adoption of the Euro was not associated with increased integration. Our results do not change when the sample is extended to include the recent crisis period.

The European Union, the Euro, and Equity Market Integration

At a time of historic challenges to the viability of the Eurozone, we assess the contribution of the EU and the Euro to equity market integration in Europe. We use a simple and essentially model free measure of bilateral market segmentation: two countries are segmented if there is a wide divergence in the valuations of their industries. We first establish that segmentation is significantly lower for EU versus non- EU members. Bilateral valuation differentials remain lower for EU members even after we control for several possible channels of integration, such as bilateral trade, direct investment positions, financial regulation, and interest rate differences. Importantly, we find that EU membership reduces equity market segmentation between member countries whether or not members have also adopted the Euro. The Euro adoption as well as the anticipation of the Euro adoption has minimal effects on market integration.

Why Do Term Structures in Different Currencies Comove

Yield curve fluctuations across different currencies are highly correlated. This paper investigates this phenomenon by exploring the channels through which macroeconomic shocks are transmitted across borders. Macroeconomic shocks affect current and expected future short-term rates as central banks react to changing economic environments. Investors could also respond to these shocks by altering their required compensation for risk. Macroeconomic shocks thus influence bond yields both through a policy channel and through a risk compensation channel. Using data from the US, the UK, and Germany, we find that world inflation and US yield level together explain over two-thirds of the covariance of yields at all maturities. Further, these effects operate largely through the risk compensation channel for long-term bonds.

Mark-to-Market Accounting and Systemic Risk: Evidence from the Insurance Industry

One of the most contentious issues raised during the recent crisis has been the potentially exacerbating role played by mark-to-market accounting. Many have proposed the use of historical cost accounting, promoting its ability to avoid the amplification of systemic risk. We caution against focusing on the accounting rule in isolation, and instead emphasize the interaction between accounting and the regulatory framework. First, historical cost accounting, through incentives that arise via interactions with complex capital adequacy regulation, does generate market distortions of its own. Second, while mark-to-market accounting may indeed generate fire sales during a crisis, forward-looking institutions that rationally internalize the probability of fire sales are incentivized to adopt a more prudent investment strategy during normal times which leads to a safer portfolio entering the crisis. Using detailed, position- and transaction-level data from the U.S. insurance industry, we show that (a) market prices do serve as ‘early warning signals’, (b) insurers that employed historical cost accounting engaged in greater degrees of regulatory arbitrage before the crisis and limited loss recognition during the crisis, and (c) insurers facing mark-to-market accounting tend to be more prudent in their portfolio allocations. Our identification relies on the sharp difference in statutory accounting rules between life and P&C companies as well as the heterogeneity in implementation of these rules within each insurance type across U.S. states. Rather than promoting a shift away from market-based information, our results indicate that regulatory simplicity may be preferred to the complexity of risk-weighted capital ratios that gives rise, through interactions with accounting rules, to distorted risk-taking incentives and potential build-up of systemic risk.

Political Risk and International Valuation

Measuring the impact of political risk on investment projects is one of the most vexing issues in international business. One popular approach is to assume that the sovereign yield spread captures political risk and to augment the project discount rate by this spread. We show that this approach is flawed. While the sovereign spread is influenced by political risk, it also reflects other risks that are likely included in the valuation analysis — leading to the double counting of risks. We propose to use “political risk spreads” to undo the double counting in the evaluation of international investment projects.

Interpreting Risk Premia Across Size, Value, and Industry Portfolios

In this paper, we model cash flow and consumption growth rates as a vector-autoregression (VAR), from which we measure the response of cash flow growth to consumption shocks. As the appropriate cash flow proxy is not unambiguous, nor likely to be measured without error, we consider three alternatives for portfolio cash flows: cash dividends, dividends plus repurchases and corporate earnings. We find that the long-run exposure of cash flows to aggregate consumption risk can justify a significant degree of the observed variation in risk premia across size, book-to-market, and industry sorted portfolios. Also, our economic model highlights the reasons for the failure of the market beta to justify the cross-section of risk premia. Most importantly, our results indicate that measured diferences in the long-run exposures of cash flows to aggregate economic fluctuations as captured by aggregate consumption movements contain very valuable information regarding diferences in risk premia. In all, our results indicate that the size, book-to-market and industry spreads are not puzzling from the perspective of economic models.
