Semi-Parametric Weak Instrument Regressions with an Application to the Risk-Return Trade-off

Recent work shows that a low correlation between the instruments and the included variables leads to serious inference problems. We extend the local-to-zero analysis of models with weak instruments to models with estimated instruments and regressors and with higher-order dependence between instruments and disturbances. This makes this framework applicable to linear models with expectation variables that are estimated non-parametrically. Two examples of such models are the risk-return trade-off in finance and the impact of inflation uncertainty on real economic activity. Results show that inference based on Lagrange Multiplier (LM) tests is more robust to weak instruments than Wald-based inference. Using LM confidence intervals leads us to conclude that no statistically significant risk premium is present in returns on the S&P 500 index, excess holding yields between 6-month and 3-month Treasury bills, or in yen-dollar spot returns.

Assessing waiting times in the clinical trajectory of patients with lung cancer

Le cancer du poumon a une incidence et une létalité parmi les plus hautes de tous les cancers diagnostiqués au Canada. En considérant la gravité du pronostic et des symptômes de la maladie, l’accès au traitement dans les plus brefs de délais est essentiel. Malgré l’engagement du gouvernement fédéral et les gouvernements provinciaux de réduire les délais de temps d’attente, des balises pour les temps d’attente pour le traitement d’un cancer ne sont toujours pas établis. En outre, le compte-rendu des indicateurs des temps d’attente n’est pas uniforme à travers les provinces. Une des solutions proposées pour la réduction des temps d’attente pour le traitement du cancer est les équipes interdisciplinaires. J’ai complété un audit du programme interdisciplinaire traitant le cancer du poumon à l’Hôpital général juif (l’HGJ) de 2004 à 2007. Les objectifs primaires de l’étude étaient : (1) de faire un audit de la performance de l’équipe interdisciplinaire à l’HGJ en ce qui concerne les temps d’attente pour les intervalles critiques et les sous-groupes de patients ; (2) de comparer les temps d’attente dans la trajectoire clinique des patients traités à l’HGJ avec les balises qui existent ; (3) de déterminer les facteurs associés aux délais plus longs dans cette population. Un objectif secondaire de l’étude était de suggérer des mesures visant à réduire les temps d’attente. Le service clinique à l’HGJ a été évalué selon les balises proposées par le British Thoracic Society, Cancer Care Ontario, et la balise pan-canadienne pour la radiothérapie. Les patients de l’HGJ ont subi un délai médian de 9 jours pour l’intervalle «Ready to treat to first treatment», et un délai médian de 30 jours pour l’intervalle entre le premier contact avec l’hôpital et le premier traitement. Les patients âgés de plus de 65 ans, les patients avec une capacité physique diminuée, et les patients avec un stade de tumeur limité étaient plus à risque d’échouer les balises pour les temps d’attente.
