The branch of economics represented by the headline "General Motors Closes Auto Plant in Wisconsin".
Answer to Problem 4P
The branch of economics represented by the headline "General Motors Closes Auto Plant in Wisconsin" is microeconomics.
Explanation of Solution
Microeconomics is the branch of economics that deals with the economic decision-making of micro units like consumers, firms, producers, labor, etc. The examples of microeconomic decisions are consumer choice, producer's choice, etc. General Motors is an individual company whose one of the plants is shut down. This is a microeconomic decision by a micro unit General Motors. Thus, the branch of economics represented by the headline "General Motors Closes Auto Plant in Wisconsin" is microeconomics.

The branch of economics represented by the headline "OPEC Action Results in a General Increase in Prices".
Answer to Problem 4P
The branch of economics represented by the headline "OPEC Action Results in a General Increase in Prices" is macroeconomics.
Explanation of Solution
Macroeconomics is the branch of economics that deals with the economics of the aggregative variables like aggregate demand, aggregate supply, inflation, unemployment, etc. An OPEC decision leading to increase in general level of prices would be a macroeconomic phenomenon since general price level is a macroeconomic variable. Hence, the branch of economics represented by the headline "OPEC Action Results in a General Increase in Prices" is macroeconomics.

The branch of economics represented by the headline "Lawmakers Worry About the Possibility of a US Recession".
Answer to Problem 4P
The branch of economics represented by the headline "Lawmakers Worry About the Possibility of a US Recession" is macroeconomics.
Explanation of Solution
Macroeconomics is the branch of economics that deals with the economics of the aggregative variables like aggregate demand, aggregate supply, inflation, unemployment, etc.Recession refers to the slowing down of economic activity characterized by falling output, prices and employment. Therefore, an issue of a possible recession would represent macroeconomic situation. Thus, the branch of economics represented by the headline "Lawmakers Worry About the Possibility of a US Recession" is macroeconomics.

Answer to Problem 4P
The branch of economics represented by the headline "Los Angeles Dodgers Make Pitcher Highest Paid Ballplayer" is macroeconomics.
Explanation of Solution
Macroeconomics is the branch of economics that deals with the economics of the aggregative variables like aggregate demand, aggregate supply, inflation, unemployment, etc. If Pitcher is declared the highest paid ballplayer, it is a national level title given to him. Thus, the branch of economics represented by the headline "Los Angeles Dodgers Make Pitcher Highest Paid Ballplayer" is macroeconomics.
