World food prices have hit an all-time high, driven up by price increases in wheat, corn, sugar, and oils. The price of wheat has doubled within a six-month period. While these soaring prices have had only a modest effect on U.S. inflation, they have devastated the world’s poor who spend a majority of their income on basic food staples.Politicians and scientists continue to argue over the cause of rising food prices. Some believe the jump in prices can be attributed to bad policies set by the U.S. Federal Reserve, and others believe that commodities speculation is to blame. But most scientists, including those from the U.S. Department of Agriculture, believe higher food prices were caused by two major factors: (1) low production due to severe weather around the world, including extreme heat in Russia, drought in Brazil, and flooding in Australia; and (2) a large portion of the world’s corn going toward ethanol production instead of food. Regardless, the world’s poor continue to suffer.Which of the following are plausible solutions to the given problem?Choose 3 answers Develop ways of growing crops indoors so weather will no longer be a factor. Reconsider tax incentives offered for production of alternative fuels. Keep U.S.-produced crops in the United States to take care of the nation's poor. Set government policies that will lower the cost of basic food staples to the poorest people. Consider the effects of greenhouse gases on climate change and set policies accordingly. Increase subsidies to encourage farmers to produce more of the basic crops such as wheat and corn. Rely on world food organizations to redistribute and ration the food in a fair and equitable way so the poor get a share.

Food prices can account for as much as 17 percent of consumer spending in advanced economies and more than 40 percent of consumer spending in more developing economies and the overall rise in food prices for 2022 was 23.1 percent globally. According to economists, such a rise is not unexpected due to the global rate of inflation. Such trends can be seen when the prices of different food items rise at a fairly consistent rate. When the price of one specific food item rises or falls outside of this trend however, it tends to point to the presence of external forces interrupting the normal supply chain by either drastically increasing or decreasing global supply of that item, which would result in a significant decrease or increase in price respectively. New research by the International Monetary Fund analyzed the rising cost of food prices from the end of 2021 through the beginning of 2022. The writers of the study posit that ------- Which choice most effectively uses data from the graph to illustrate the claim? the price of rice indicates that some external force increased the global supply of rice in September 2021.eliminatethe price of wheat indicates that some external force decreased the global supply of wheat in March 2022.eliminatethe fluctuations of food price from September 2021 to July 2022 can be largely attributed to the expected increase caused by global inflation.eliminatethe drop in price of wheat from March 2022 to July 2022 was indicates that global demand for wheat was less in July than it was in March. eliminate

Food versus fuel – a classic application of opportunity costWorld food prices have been rising since 2007. The riseshave been particularly strong for vegetable oil, wheatand corn. This has resulted in civil unrest and riots inmany poor countries. In response, for example in India,exports of grain products have been banned in order tomaintain supplies in the home market. China has alsotaken steps to quell the rise in the price of cooking oil.One factor that has been driving up world food priceshas been the increased demand for biofuels which areproduced from agricultural crops traditionally used forfood and animal feed. The most important biofuel isethanol which is produced from corn and sugar cane.These crops are very important sources of biofuelproduction in the USA, Brazil and India.As global oil prices increase, there is a growing needfor the increased agricultural production of corn, soyabeans and sugar cane for conversion into biofuels. Thismay be good news for farmers producing these productsand indeed, for users of biofuels. It is not good newsfor livestock farmers who experience increased feedprices or for consumers who experience rising grain andmeat prices.Source: Adapted from S.

Some underlying factors of the recent world food crisis discussed in lecture include:Question 26Select one:a.demand for biofules and rising price of oilb.declining agricultural productivityc.growing global demand for meatd.all of the answers are valid

Between 2004 and 2011, we observed a significant increase in commodity prices. In Australia, we would expect that this increase would cause: Group of answer choicesa larger increase in the CPI compared to the GDP deflator. an equal increase in the CPI and GDP deflator. a larger increase in the GDP deflator compared to the CPI. no change in the CPI and an increase in the GDP deflator. no change in the GDP deflator and an increase in the CPI.
