Accordingly, identify 5 news items. These items could be current or could be historical. The only thing is that the news and or the situation must be microeconomic related. In other words, consumer behavior, labor disputes, pricing strategies, merger and acquisition, healthcare, education, pollution, welfare, philosophy and systems of taxation, etc. are relevant microeconomic topics, while Federal Reserve decisions, government spending, inflation, unemployment, government debt, etc. are (normally) not since they are more macroeconomic oriented.
