Investors typically measure an asset’s potential to diversify a portfolio by its correlations with the portfolio’s other assets, but correlation is useful only if it provides a good estimate of how an asset’s returns co-occur cumulatively with the other asset returns over the investor’s...

In July 2017, issued a call for papers for a special issue on "The Practice of Replication." In that call, the journal explained that there was no generally accepted procedure for how to do a replication. Likewise, there was no generally accepted standard for determining whether a replication...

Complexity in financial markets is slowly overwhelming canonical statistical modelling. With global crises which stemming from contagion effects becoming more frequent, new tools for financial distress transmission c apture are needed. Graph theory , with its branch on minimum spanning trees can...

This paper examines the econometric causal model for policy analysis developed by the seminal ideas of Ragnar Frisch and Trygve Haavelmo. We compare the econometric causal model with two popular causal frameworks: Neyman-Holland causal model and the do-calculus. The Neyman-Holland causal model...

Binomial, and log linear models. We show why these interaction term coefficients cannot be interpreted as a DIS or … how interaction terms can be easily transformed into a DIS and derive the asymptotic distribution of this estimator. We …

We consider the implications of choosing weighting matrix (projection) on the asymptotic risk of the restricted GMM and WLS estimators. Decomposing expected square error risk into variance part and squared bias part, we show that for both GMM and WLS its variance part is minimized by choosing...

requires repeated re-calculation of the estimator. In Honoré and Hu (2015), we propose a computationally simpler bootstrap … contribution here is that rather than repeated re-calculating the U-statistic-based estimator, we can recalculate a related … estimator based on single-sums. A simulation study suggests that the approach leads to a good approximation to the standard …

Identification in a regression discontinuity (RD) design hinges on the discontinuity in the probability of treatment when a covariate (assignment variable) exceeds a known threshold. If the assignment variable is measured with error, however, the discontinuity in the first stage relationship...
