Before revision:  Our analysis of the ITN detects indirect effects that are not captured by traditional macroeconomic analyses focused only on weighted first-order country-specific properties, and highlights the limitations of models and theories that overemphasize the need to reproduce and explain such properties .
After revision:  Our analysis of the ITN . In the binary case, they do not focus on the degree sequence and hence cannot characterize or replicate higher-order properties. In the weighted case, they generally focus on the strength sequence, but the knowledge of the latter is not enough in order to understand or reproduce indirect effects .
