DESCRIPTION:*Post-Double-Lasso is becoming the most popular method for esti
 mating linear regression models with many covariates when the purpose is to
  obtain an accurate estimate of a parameter of interest\, such as an averag
 e treatment effect. However\, this method can suffer from substantial omitt
 ed variable bias in finite sample. We propose a new method called Post-Doub
 le-Autometrics\, which is based on Autometrics\, and show that this method 
 outperforms Post-Double-Lasso. Its use in a standard application of economi
 c growth sheds new light on the hypothesis of convergence from poor to rich
  economies.**I analyse the transmission of Quantitative Easing and assess i
 ts distributional effects in a heterogeneous monetary union. Focusing on Eu
 ropean Monetary Union (EMU)\, I capture two types of heterogeneity: cross-
 country –- debt profiles (long-term debt liquidity\, short-term to long-
 term debt\, debt-to-GDP ratio) and within-country heterogeneity -- unequa
 l households financial participation. I develop a Two-Country\, Two-Agent N
 ew Keynesian model with a liquidity constraint\, calibrated to EMU core and
  peripheral countries during the Global Financial Crisis. My main finding i
 s that heterogeneity within a monetary union critically shapes the impact o
 f Quantitative Easing. Across countries\, differences in debt profiles shap
 e the the aggregate response of output via the portfolio rebalancing channe
 l. Bond liquidity governs the strength of the portfolio reallocation while 
 short-to-long-term debt ratio drives the direction of these reallocations. 
 Within countries\, disparities in households’ access to financial markets
  condition both the aggregate output response and the distributional effect
 s of Quantitative Easing.\\n\\nContact: Alexandre Arnout : alexandre.arnout
