No. Its success is not guaranteed. Firstly, the Marshall-Lerner condition must hold (PEDx + PEDm > 1). Secondly, the J-curve effect means the deficit will likely worsen in the short term before it improves. Thirdly, devaluation raises the price of imported raw materials, which can cause cost-push inflation, eroding the competitive advantage gained.

Not necessarily. While they can be effective in reducing import spending, they do so by slowing down the entire economy. This can lead to a recession, rising unemployment, and falling living standards. It is often described as 'curing the disease by killing the patient', highlighting a severe conflict with other major macroeconomic objectives.

It also harms domestic consumers through higher prices and less choice, and it protects inefficient domestic firms from international competition, leading to a misallocation of resources.
