A specific concept of structural model is used as a background for discussing the structurality of its parameterization. Conditions for a structural model to be also causal are examined. Difficulties and pitfalls arising from the parameterization are analyzed. In particular, pitfalls when...

literature, this estimator is consistent, asymptotically normal and very stable across partitions of the sample. Further, we show … in an extensive simulation study that this estimator outperforms in finite samples the logs, blocks and runs estimation … methods. Finally, we apply this new estimator to test for clustering of extremes in monthly time series of unemployment growth …

Allowing for misspecification in the linear conditional quantile function, this paper provides a new interpretation and …–Bassett estimator minimizes a weighted distribution approximation error, defined as F Y (X ′ β(τ)|X)−τ , i.e., the deviation of the … conditional distribution function, evaluated at the linear quantile approximation, from the quantile level. The second result …
