Abstract

El objetivo principal en este trabajo fue usar regresion LASSO (Least Absolute Shrinkage and Selection Operator) como metodo de seleccion de instrumentos en la estimacion de minimos cuadrados en dos etapas (MC2E) en un sistema de ecuaciones simultaneas propuesto para realizar un analisis econometrico del mercado de carne de bovino en Mexico en el periodo 1972-2011. Un factor determinante en el desempeno de los estimadores es el grado de correlacion de los instrumentos con las variables endogenas en la primera etapa. Cuando los instrumentos son debiles, los estimadores de MC2E son inconsistentes, sesgados, y tienen varianzas grandes; los resultados asintoticos fallan incluso con muestras grandes. Los resultados muestran que mediante LASSO es posible seleccionar instrumentos relevantes, y obtener mejores estimadores que redunden en un mejor diseno de politicas.
