Currently the economic growth forecast of South Africa isn't looking as promising as thought, while  additionally its budget deficit is going to be higher than promised. 4.8 percent of GDP instead of 4.6 percent. According to the president, Gordhan, this is due to slower economic growth and not due to increase in government spending. He emphasizes that there will be no increase in government spending. From a neoclassical side this is a good thing as an increase in spending accompanied by a decrease in taxes will only further increase the governments budget deficit. The mining strikes ongoing in South Africa have had two significant consequences. 1. more people have become unemployed due to the strikes for higher wages.2. Offshore investors are worried that the government will increase spending to ease the social tensions. As a result both decreases AD as there is less consumption and investment. 

At the moment globally there has been a spike in food prices. One of the causes has been the severe droughts in the United states which have driven up the food prices. In response to this inflation the government of Brazil decided to reduce taxes on basic household goods to support an economic recovery. This action also leads to stabler prices, which is one of the macro-economic goals of a country. The tax break on household goods allows for a increase in consumption as consumers will feel wealthier and have an increase in purchasing power. As a result this will increase Brazil's GDP to a certain extent as Consumption is one of the factors that influence the gross national product. 

This article describes how the Brazilian government tries to increase investment and consumption through tax cuts. In particular on trucks, machinery, and automobiles the government reduces or gives an extension on the taxes. Another measure to stimulate investment in the country is via reducing its interest rate to an all-time low of 7.5 %.
