Query: Reconstruction methods for networks: the case of economic and financial
  systems   When studying social, economic and biological systems, one has often access
to only limited information about the structure of the underlying networks. An
example of paramount importance is provided by financial systems: information
on the interconnections between financial institutions is privacy-protected,
dramatically reducing the possibility of correctly estimating crucial systemic
properties such as the resilience to the propagation of shocks. The need to
compensate for the scarcity of data, while optimally employing the available
information, has led to the birth of a research field known as network
reconstruction. Since the latter has benefited from the contribution of
researchers working in disciplines as different as mathematics, physics and
economics, the results achieved so far are still scattered across heterogeneous
publications. Most importantly, a systematic comparison of the network
reconstruction methods proposed up to now is currently missing. This review
aims at providing a unifying framework to present all these studies, mainly
focusing on their application to economic and financial networks.
