The position of countries in a network of external portfolio investments provides a novel macroeconomic characteristic to explain violations of uncovered interest rate parity. I derive a network centrality measure, where central countries are highly integrated with key suppliers of tradeable...

We construct correlation-based networks linking 86 assets (stock indices, bond indices, foreign exchange rates, commodity futures, and cryptocurrencies) and analyze the impact of asset selection on portfolio optimization using different centrality measures (including degree, eigenvector,...
