We consider a two-step estimator which first selects a small number of \u2018important\u2019 covariates through a localised lasso-type procedure, and then, in a second step, estimates the treatment effect by including the selected covariates linearly into the usual local linear estimator. We provide an in-depth analysis of the algorithm\u2019s theoretical properties, showing that, under an approximate sparsity condition, the resulting estimator is asymptotically normal, with asymptotic bias and variance that are conceptually similar to those obtained in low-dimensional settings. Bandwidth selection and inference can be carried out using standard methods. We also provide simulations and an empirical application.<\/jats:p>","DOI":"10.1093\/ectj\/utac029","type":"journal-article","created":{"date-parts":[[2022,12,22]],"date-time":"2022-12-22T19:50:23Z","timestamp":1671738623000},"page":"105-123","source":"Crossref","is-referenced-by-count":5,"title":["Inference
