摘要

Economic systems are recognized as complex systems that can be modeled as complex networks. Analyzing and simulating with the outcoming networks parameters can be obtained the vulnerability and robustness of system's network, assisting the developing of economic policies. In present work we built up an economic weighted directed network between the catalogued labors, the productive sub-sectors, based on 4-digits NAICS-2018, and the eight common household expenses. Weighting edges with total household incomes and total amount paid for each expense. The network is constructed with a sample size of more than one hundred-thirty thousand households. With complex network metrics and adding an inflation rate to each main Expense category, the simulation was performed obtaining key economic properties such as wealth distribution per household and sectors vulnerabilities as well as system robustness.
