Trade or freedom of trade is an economic concept that can be understood towards domestic trade and abroad. Towards the interior it is equivalent to the freedom of enterprise in a free market economy (economic freedom), and refers to the absence of obstacles that impede the access of economic agents to commercial activity, expressing themselves in different freedoms (freedom of prices , freedom of schedules, freedom to open establishments, freedom of hiring, etc.). Economic liberalism argues that the main obstacles to freedom of internal trade are state interventionism and the formation of interest groups: unions, employers, or, historically, the unions that during the Old Regime established rigid regulations to hinder access to trades, industries and businesses.
