* "Consuetudo, vel lex mercatoria, or the Ancient Law Merchant" (1622): This work is a comprehensive treatise on commercial law and practice, focusing on topics like bills of exchange, insurance, and maritime law. It was influential in shaping legal thought and practice during the early modern period.
* "The Maintenance of Free Trade, as Well By Sea As By Land" (1622): This work is a key statement of Malynes's mercantilist views. It argues that a nation's wealth is determined by its stock of gold and silver and that government intervention is necessary to maintain a favorable balance of trade.
* "Lex Mercatoria, or the Ancient Law Merchant" (1629): This work is a revised and expanded version of his earlier treatise on commercial law. It further elaborated on his views on international trade and the role of the merchant in society.
* "The Center of the Circle of Commerce" (1623): This book argued against the overvaluation of money, advocating for a stable currency and the importance of credit in stimulating trade.
* "England's View in the Unmasking of Two Principal Abuses, One in the Use of Foreign Coins, and the Other in the Exportation of the Kings Coin" (1603): This work was written early in his career and focused on the challenges of managing currency in England.
These works established de Malynes as a leading voice in the development of early modern economic theory. His mercantilist ideas, while not universally accepted today, were influential in shaping economic policies during his lifetime.
