The fragility of the global trading system

We use a parsimonious gravity framework to simulate and compare five potential shocks to the global shipping system: closures of the Panama Canal, the Suez Canal, and the Strait of Malacca, and openings of the Northwest ...Read more...

Sticky gravity

International trade flows show strong persistence over time. Standard static gravity models cannot rationalize this persistence and lack a micro-foundation for including lagged trade flows as a determinant of current tra...Read more...

Networks in trade - evidence from the legacy of the Hanseatic league

We study trade networks following the decline of the Hanseatic League, using a novel trade data set that covers cities and captains in Northern Europe over 190 years. By the time of its dissolution in 1669, trade on form...Read more...
