To connect with researchers in international economics and learn about publishing, it is recommended that you attend conferences. It is recommended that you attend major conferences such as the American Economic Association (AEA) or the European Economic Association (EEA) to meet experts in the field. You may also wish to consider joining professional associations, such as the AEA. Another option is to use academic platforms, such as ResearchGate and Google Scholar, to engage with researchers. You could also try networking online, for example by connecting with economists on LinkedIn or Twitter. Alternatively, you could contact researchers whose work interests you by email to request advice. Finally, you might find it helpful to engage with journals, for instance by reading leading journals and reviewing their editorial boards. Following these steps should help you to network with researchers and gain a better understanding of the publication process.
