Decomposing Excess Returns in Stochastic Linear Models
Lin, Carl - 2012
We present a theorem helpful in estimating the mean and variance of a linear function with arbitrary multivariate randomness in its coefficients and variables. We derive a generalized decomposition result from two random linear functions in which the result can be applied to most models using...

Testing CAPM with a Large Number of Assets
Pesaran, M. Hashem - 2012
This paper is concerned with testing the time series implications of the capital asset pricing model (CAPM) due to Sharpe (1964) and Lintner (1965), when the number of securities, N, is large relative to the time dimension, T, of the return series. In the case of cross-sectionally correlated...

The Identification and Economic Content of Ordered Choice Models with Stochastic Thresholds
Cunha, Flavio - 2008
This paper extends the widely used ordered choice model by introducing stochastic thresholds and interval-specific outcomes. The model can be interpreted as a generalization of the GAFT (MPH) framework for discrete duration data that jointly models durations and outcomes associated with...

A Job Ladder Model with Stochastic Employment Opportunities
Bradley, Jake - 2018
We set up a model with on-the-job search in which firms infrequently post vacancies for which workers occasionally apply. The model nests the standard job ladder and stock-flow models as special cases while remaining analytically tractable and easy to estimate from standard panel data sets....

Stochastic Complementarity
Manzini, Paola - 2018
The Hicksian definition of complementarity and substitutability may not apply in contexts in which agents are not utility maximisers or where price or income variations, whether implicit or explicit, are not available. We look for tools to identify complementarity and substitutability satisfying...

Testing for Restricted Stochastic Dominance
Davidson, Russell; Duclos, Jean-Yves - 2006
Asymptotic and bootstrap tests are studied for testing whether there is a relation of stochastic dominance between two distributions. These tests have a null hypothesis of nondominance, with the advantage that, if this null is rejected, then all that is left is dominance. This also leads us to...

Predictability of Asset Returns and the Efficient Market Hypothesis
Pesaran, M. Hashem - 2010
This paper is concerned with empirical and theoretical basis of the Efficient Market Hypothesis (EMH). The paper begins with an overview of the statistical properties of asset returns at different frequencies (daily, weekly and monthly), and considers the evidence on return predictability, risk...

The Cyclical Volatility of Labor Markets Under Frictional Financial Markets
Petrosky-Nadeau, Nicolas - 2010
Financial frictions are known to raise the volatility of economies to shocks (e.g. Bernanke andGertler 1989). We follow … this line of research to the labor literature concerned by the volatility of labor market outcomes to productivity shocks … are a good candidate to solve the volatility puzzle and rejoin Pissarides (2009) in arguing that hiring costs must be …

They are Even Larger! More (on) Puzzling Labor Market Volatilities
