Antitrust and trade regulation jobs focus on laws of competition and trade as among sovereign nations and private companies. These kinds of legal jobs are concerned with promoting competition and fair business practices domestically and globally in an effort to keep consumer prices down and promote free, fair and productive flow of goods and services across borders. Antitrust lawyers work with major antitrust laws such as the Clayton and Sherman Acts, which were passed to ensure that no single company (or combination of companies) is able to dominate the market, fix prices and engage in other anti-competitive behavior. Trade lawyers work with major laws and policies regarding trade between states and among nations. Trade lawyers must be familiar with the rules and regulations of the World Trade Organization and other trade organizations that seek to regulate trade and the imposition of tariffs and sanctions between nations in the global marketplace.
