Based at the Department of Economics of the Federal University of Rio Grande do Norte, NEDLab is a research group focused on economic systems whose behavior is shaped by feedback, interdependence, heterogeneity, cumulative processes, and institutional constraints. Its work examines how economies amplify shocks, accumulate fragility, transmit disturbances across connected structures, and move between different regimes over time.
The group’s research is organized around three closely related domains: macroeconomic dynamics, regimes, and structural change; financial fragility, interconnectedness, and systemic instability; and analytical, computational, and statistical methods for nonlinear economic models. Across these domains, NEDLab combines economic theory, nonlinear dynamics, recursive methods, network analysis, statistical tools, and computational modeling.
This perspective informs research on regime shifts, financial cycles, systemic risk, shock propagation, and structural transformation, while also motivating methodological work on the analysis, simulation, estimation, and validation of nonlinear economic models. More broadly, NEDLab is concerned with how economic systems evolve through feedback mechanisms, interdependence, cumulative processes, institutional conditions, and changes in their underlying structure.
NEDLab is also conceived as a collaborative and international research network. It welcomes interaction with scholars and students from economics, finance, mathematics, statistics, data science, engineering, computer science, and related fields. Its activities include joint research projects, seminars, methodological workshops, student training, and academic exchange.
NEDLab is listed as a certified research group in the CNPq Directory of Research Groups in Brazil.
