To determine whether each newspaper headline deals with a microeconomics (micro) or a macroeconomics (macro) issue, we can look at the scope and scale of the topic.

Microeconomics focuses on individual actors (individuals, households, companies) and their interactions in specific markets. It examines how individual choices and decisions affect the allocation of resources. Microeconomics often deals with issues related to supply and demand, pricing, production, consumer behavior, etc.

Macroeconomics, on the other hand, studies the overall behavior and performance of an economy as a whole. It looks at aggregate measures such as national income, GDP, inflation, unemployment, exchange rates, etc. Macroeconomics examines the interactions between different sectors of the economy and the role of government in managing economic policies and outcomes.
