2015/9/18
Comparisons of within and between estimators using the conventional Hausman test may besubject to statistical problems if the within variation is not su￠ ciently large. Adopting an alternative asympto...
ESTIMATING WELFARE IN INSURANCE MARKETS USING VARIATION IN PRICES
INSURANCE MARKETS PRICES
2015/7/17
We provide a graphical illustration of how standard consumer and producer
theory can be used to quantify the welfare loss associated with inefficient pricing

An ADMM Algorithm for a Class of Total Variation Regularized Estimation Problems
Signal processing algorithms stochastic parameters parameter estimation
2015/7/9
We present an alternating augmented Lagrangian method for convex optimization problems where the cost function is the sum of two terms, one that is separable in the variable blocks, and a second that ...
The Maturity of Debt Issues and Predictable Variation in Bond Returns
Borrowing and Debt Bonds Investment Return Financial Markets Forecasting and Prediction
2015/5/13
The maturity of new debt issues predicts excess bond returns. When the share of long term debt issues in total debt issues is high, future excess bond returns are low. This predictive power comes in t...
