Trade protection is the deliberate attempt to limit imports or promote exports by putting up barriers to trade. Despite the arguments in favour of free trade and increasing trade openness, protectionism is still widely practiced.
The main arguments for protection are:
Protect sunrise industries: Barriers to trade can be used to protect sunrise industries, also known as infant industries, such as those involving new technologies. This gives new firms the chance to develop, grow, and become globally competitive.
Protection of domestic industries may allow them to develop a comparative advantage. For example, domestic firms may expand when protected from competition and benefit from economies of scale. As firms grow they may invest in real and human capital and develop new capabilities and skills. Once these skills and capabilities are developed there is less need for trade protection, and barriers may be eventually removed.
Protect sunset industries: At the other end of scale are sunset industries, also known as declining industries, which might need some support to enable them to decline slowly, and avoid some of the negative effects of such decline. For the UK, each generation throws up its own declining industries, such as ship building in the 1950s, car production in the 1970s, and steel production in the 1990s.
Protect strategic industries: Barriers may also be erected to protect strategic industries, such as energy, water, steel, armaments, and food. The implicit aim of the EUs Common Agricultural Policy is to create food security for Europe by protecting its agricultural sector.
Protect non-renewable resources: Non-renewable resources, including oil, are regarded as a special case where the normal rules of free trade are often abandoned. For countries aiming to rely on oil exports lasting into the long term, such as the oil-rich Middle Eastern economies, limiting output in the short term through production quotas is one method employed to
