Quantitative analysis of trade networks: data and robustness

Abstract A common issue in trade network analysis is missing data, as some countries do not report flows. This paper explores what constitutes suitable how to deal with and demonstrates the results using key measures. All-to-all potential connectivity of between considered a starting point, contrast approach analyzing networks only that actually In order fill gap two approaches, more complete dataset than just reporting reconstructed robustness studying this bigger examined. The difference imputed actual adjacency matrices evaluated based on several centrality are illustrated ten commodity groups from United Nations Database, which demonstrate under proposed reconstruction procedure ranks change significantly size becomes or smaller. Further, degree distributions trading partners same within their uncertainties. So, it robust study provides richer insights into relations, particularly for nonreporting countries.
