Combining Panel Data Sets with Attrition and Refreshment Samples
Hirano, Keisuke; Imbens, Guido W.; Ridder, Geert; … - 2021
In many fields researchers wish to consider statistical models that allow for more complex relationships than can be inferred using only cross-sectional data. Panel or longitudinal data where the same units are observed repeatedly at different points in time can often provide the richer data...

International Risk Sharing in the Short Run and in the Long Run
Baxter, Marianne - 2011
International risk-sharing has far-reaching implications both for economic policy and for basic research in economics. When countries do not share risk, individuals in those countries experience fluctuations in their consumption levels that are undesirable and possibly unnecessary. This paper...

On the Correlation Structure of Microstructure Noise : A Financial Economic Approach
Diebold, Francis X. - 2010
volatility estimation. In particular, we use market microstructure theory to derive the cross-correlation function between latent … returns and market microstructure noise, which feature prominently in the recent volatility literature. The cross-correlation … geometrically. If market makers are sufficiently risk averse, however, the cross-correlation pattern is inverted. Our results are …

Testing the Correlated Random Coefficient Model
Heckman, James J. - 2012
The recent literature on instrumental variables (IV) features models in which agents sort into treatment status on the basis of gains from treatment as well as on baseline-pretreatment levels. Components of the gains known to the agents and acted on by them may not be known by the observing...

The Lucas Orchard
Martin, Ian - 2011
This paper investigates the behavior of asset prices in an endowment economy in which a representative agent with power utility consumes the dividends of multiple assets. The assets are Lucas trees; a collection of Lucas trees is a Lucas orchard. The model generates return correlations that vary...

Estimating the Effects of Large Shareholders Using a Geographic Instrument
Becker, Bo - 2011
Large shareholders may play an important role for firm performance and policies, but identifying this empirically presents a challenge due to the endogeneity of ownership structures. We develop and test an empirical framework which allows us to separate selection from treatment effects of large...

Hybrid Tail Risk and Expected Stock Returns : When Does the Tail Wag the Dog?
Bali, Turan G. - 2013
We introduce a new, hybrid measure of stock return tail covariance risk, motivated by the under-diversified portfolio holdings of individual investors, and investigate its cross-sectional predictive power. Our key innovation is that this covariance is measured across the left tail states of the...

International Asset Allocation with Time-Varying Correlations
Bekaert, Geert - 2008
It is widely believed that correlations between international equity markets tend to increase in highly volatile bear markets. This has led some to doubt the benefits of international diversification. This article solves the dynamic portfolio choice problem of a US investor faced with a...

The Forecasting Ability of Correlations Implied in Foreign Exchange Options
Campa, José Manuel - 2008
This paper evaluates the forecasting accuracy of correlation derived from implied volatilities in dollar-mark, dollar …-yen, and mark-yen options from January 1989 to May 1995. As a forecast of realized correlation between the dollar-mark and … dollar-yen, implied correlation is compared against three alternative forecasts based on time series data: historical …

Risk Reduction in Large Portfolios : Why Imposing the Wrong Constraints Helps
Ma, Tongshu - 2002
Mean-variance efficient portfolios constructed using sample moments often involve taking extreme long and short positions. Hence practitioners often impose portfolio weight constraints when constructing efficient portfolios. Green and Hollifield (1992) argue that the presence of a single...
