DESCRIPTION:*Selecting relevant variables in a model is a common problem fa
 ced by economists in general and in particular in causal effect estimation 
 models. We show\, with simulation evidence that autometrics-based methods p
 erform well in general\, and especially perform well when lasso-based metho
 ds fail. We apply these methods to two application in real database. We ret
 ain that autometrics-based methods should be preferred to lasso-based metho
 ds for their stability and their property for allowing to control the numbe
 r of irrelevant variable selected.**The disparities in economic activity ac
 ross and within regions have been one of the most studied empirical regular
 ities due to their implications for social and economic inequalities. Gover
 nments have implemented place-based policies to promote the economic develo
 pment of their most remote and lagged areas and so help to mitigate their r
 egional disparities. Despite the high prevalence of developing economies im
 plementing this policy tool\, the existing literature on place-based polici
 es has predominantly focused on examining their effects in developed econom
 ies. Nevertheless\, the experience with place-based policies in developed c
 ountries can hardly be transferred to less-developed economies where a subs
 tantial share of their labour force is employed informally. To shed light o
 n these\, this paper examines the effects of the Free Economic Zones (FEZs)
  regime established in Colombia in 2005. Based on a novel data set that com
 bines georeferenced data on FEZs\, municipalities and household characteris
 tics\, I measure the regional effects of the construction of these zones on
  labour market outcomes\, particularly focusing on informality\, using a no
 vel IV strategy. Preliminary findings suggest that the Free Economic Zones 
 regime increases the population and employment in the regions hosting a zon
 e. To assess the aggregate effects of these policies\, I aim to construct 
 a quantitative spatial economic model that incorporates labour market frict
 ions and imperfectly enforced regulations\, heterogeneous firms sorting int
 o the formal or informal sector\, and explains how the input-output linkage
 s between firms within and outside the zones\, influence the generation or 
 destruction of informal employment opportunities.\\n\\nContact: Camille Hai
