Which of the following is not always true with respect to a per unit tax on suppliers of a commodity where the demand curve is downward sloping and the supply curve is upward sloping?
It will result in an increase in the price the consumer pays for the commodity in the market.

Rangimarie consumes two goods, X and Y, and is currently consuming optimally – that is, in a utility maximising fashion. Her marginal utility (MU) from another unit of X is 5 and her MU from another unit of Y is 10. If X costs $1 per unit and Rangimarie’s income is $100, what can we conclude about the price of Y?
It must be E0.50
It must be E1
It must be E2
There is not enough information to identify the price of Y exactly.
If the substitution effect of a price change moves quantity demanded in the opposite direction to the income effect, then we can tell that:

A price ceiling is most likely to:
lead to a reduction in the volume of transactions as we move down the supply curve, below the equilibrium price, to the price ceiling
lead to a reduction in the volume of transactions as we move up the demand curve, above the equilibrium price, to the price ceiling.
lead to excess supply
be effective only if set at a level above the equilibrium price
If a firm is a price-taker on its input markets and experiences diminishing marginal returns to each factor, then as output rises we can definitely conclude that:
the firm experiences decreasing returns to scale

The following table gives the value of each meal to you (i.e., the maximum you would be willing to pay for such a meal) and the price of each meal. Meal Fish Chicken Value E15 E12 Price E20 E10 In order to maximise your consumer surplus you should:-
definitely choose the Fish.
choose the Chicken if everyone else chooses the Chicken.
definitely choose the Chicken.
choose the Fish only if everyone else chooses the Chicken.

some prices are rising faster than others
the economy’s overall price level is rising
the economy’s overall price level is high, but not necessarily rising
the economy’s overall output of goods and services is rising faster than the economy’s overall price level.

keep inflation as low as possible
maintain a stable exchange rate
keep inflation between 1% and 3% on average over the medium term
keep unemployment as low as possible subject to maintaining inflation below 5%.

the impact of the policy may last longer than the problem it was designed to offset.
