Answer 1

Answers:

1] b. holding constant all other variables.

Explanations:This commonly-used phrase stands for 'all other things being unchanged or constant'. It is used in economics to rule out the possibility of 'other' factors changing, i.e. the specific causal relation between two variables is focused.

2]b. nominal variable

Explanation: The nominal values of something are its money values in different years.

3]b. Money is important in macroeconomics but not microeconomics.

As microeconomics is concerned with functioning of industries, but not the economy. Eg: macroeconomics is concerned with how salaries are determined in labor markets and macroeconomics deals with whole economy.

4]a. Positive economics is descriptive and predictive; normative economics is prescriptive.

Explanation:Positive Economics is a branch of economics that has an objective approach, based on facts. It analyses and explains the casual relationship between variables. The economics that uses value judgments, opinions, beliefs is called normative economics.

5]C: the quantity of a good demanded increases as the price declines.

The demand for good is an inverse relationship between price and quantity. The equation of the demand curve gives the quantity demanded as a function of price. The graphical relationship between price and quantity demanded is depicted by the demand curve. Any point on the demand curve shows the quantity consumer demands for any particular price. The inverse demand curve is represents price as a function of quantity.

6]b. The demand curve shifts to the left.

Due to increase in price of beads, the demand curve shifts to the left.

7] A. The demand curve for bread shifts to the right.

8]d. An increase in the price of flour

9]a. at every price, firms find producing the good to be more profitable.

An improvement in technology shifts the supply curve outward because at every price, firms find producing the good to be more profitable.

10]b. The demand for bread

11]d. If producers expect prices to rise in the future, they supply less at every price.

12]b. the quantity supplied exceeds the quantity demanded.

13]b. rise.

If demand for bread increases at every price, the equilibrium price of bread will rise

14]b. at the original equilibrium price, there is excess supply.

If the demand for bread declines, then at the original equilibrium price, there is excess supply.
