You can read US Code. I think it's only federal law, because it is foreing trade and interstate commerce. In Europe there is only European Law, and State law but nowdays are the same

Check the "Buy America" act which restricts the purchase of materials and supplies on federally funded construction projects.

Thank you so much for your kind answer @Mr. Gransberg and @Mr. Castoldi.

Dear Prof. Patrick Navatte,

Thank you for kind response. I have gone through the paper.The paper nicely exploit change in regulation in retail industry to solve endogeneity problem. I am also looking for similar shock (e.g. change in state level law in USA). I am reading literature and have asked many law & finance professors BUT have not got any mechanism to solve endogeneity issue in trade credit.

Thank you again for your help.

Sincerely,

Masud
