Abstract

The authors observed few sectors with many connections and many sectors with few connections, “in the Brazilian input-output network,” which meant that sectoral idiosyncratic shocks may lead to aggregate fluctuations.Design/methodology/approachThe authors considered the Brazilian input–output tables for the years 2010 and 2015 and found a significant asymmetry in the roles that sectors play as input suppliers to others.FindingsGeneralized Pareto exponents decreased from one period to the other, which suggested that the input–output network has become more vulnerable to shocks.Practical implicationsThe authors identified real estate as the most important sector and, given its high connectivity, shocks to it could become a major driver of the Brazilian business cycle.Originality/valueThis is the first paper examining the asymmetric structure of the Brazilian input–output table, and results are compared with those for the US table.
