### Is an "arms race" between wages and inflation inevitable?

### Is an "arms race" between wages and inflation inevitable?

As the 1muflon1 answer states the best argument you are already making is that single employer committing to such policy does not matter. This would not necessarily be true if every employer would try ...

### Why doesn't it matter, whether you draw Demand and Supply Curves as arcs, or straight lines?

It doesn’t matter if you are just demonstrating some simple concept such as shift of demand or supply curve as in pictures above, because as long as the supply and demand are continuous and at ...

### What should a producer do in this scenario?

Scarcity has nothing to do with what you ask. To make this interesting, suppose the supplier did not know before hand of the demand curve they would face (because if they did, they would produce less)....

### Should firecrackers which disturb neighbours be a production externality or consumption externality?

### How price is determined in the following monopoly model question?

So far so good for part (a). The basic idea for part (b), is that if the parking lot goes first to set the price first, the store is going to have to allow the costumers to get at least enough ...

### Different methods to calculate price elasticity

For a differentiable function $V(P)$ the elasticity, more precisely the point elasticity, at price $P$ is defined as $\frac{dV}{dP}\frac{P}{V}$. This corresponds to the local rate of change of the ...

### Different methods to calculate price elasticity

Hint: Suppose you use Methodology 1 but take the percentages of the values in $(V,P)_2$ instead of $(V,P)_1$. Then $\%\Delta V= 50\%$ and $\%\Delta P = -28\%$ giving $\epsilon=-1.79\%$. What does ...

### Why does supply (and demand) shift left and right as opposed to up and down?

The supply curve is defined by a function $Q_{S} = a + bP$. When plotting on a price-quantity graph, we have to invert the function: $P = -\frac{a}{b} + \frac{Q_{S}}{b}$. We set $Q_{S}=0$ to get the y-...

### Why don't producers of goods with inelastic demand refuse to increase supply?

That's because "farmers" as a collective is not a decision maker. Decisions, e.g. on how much food to burn, are made by individual farmers. Now an individual farmer, by her own decision, has ...

### When talking about the supply curve, does a price increase always result in an increase in quantity sold?

The answer should be false. Law of supply states that quantity supplied increases in price. Quantity supplied $\neq$ quantity sold. For example if we have supply given by: $S= 10 +p$, then if price ...

### How does artificial scarcity benefit the seller?

First it is not appropriate to call it scarcity or artificial scarcity, since in economics that term has special technical meaning. Better term would be output/supply restriction. Restricting output ...

### Is the supply and demand elasticity equal at the equilibrium?

It is not true that at the equilibrium point the elasticity of demand is equal to the elasticity of supply. This is a coincidence in your particular example, depending on the fact that the slope of ...

### Individual Consumers Representation on the Demand Curve

### why is increasing price not more profitable when the demand is unitary elastic?

The theory says that total revenue remains the same. That is not the same as claiming total profit is same. Total revenue is by definition given as a price times quantity: $R=PQ$. Total profit on the ...

### If the government subsidizes electric vehicle (EV) purchases , then we can predict a higher price for non-EV vehicles?

A couple of things: In a competitive market, the supply curve of a good is based on the marginal cost of producing that good, so there will be no shift in the supply curve. Think about where the ...

### When talking about the supply curve, does a price increase always result in an increase in quantity sold?

This is a trick question, apparently with an educational intent. Supply and Demand curves are curves that reflect intentions, not realized events. Statement A: Supply curves slope upwards is ...

### tax imposition on supply and demand curve

If you have taxes, it is important to distinguish between the price that consumers pay $p_D$ and the price that producers receive $p_S$. Assume that the demand curve and the supply curve are linear, ...

### tax imposition on supply and demand curve

Let $p_d$ be the consumer price and let $p_s$ be the producer price. If there is a specific tax $t$ on consumption, then a consumer pays $t$ on top of the producer price $p_s$, so that $p_d=p_s+t$. ...

### How do free goods change the equilibrium price?

Response to original question It depends on parameters that you assume there might be no effect or some effect. Market price is given such that $S(p)=D(p)$, supplying 3 extra units of good for free to ...

### About the basics in marginal benefit

My lecturer said that it is also the maximum willingness to pay for an extra unit of good. Why so? This comes just from the definition. E.g. if my marginal benefit of one extra bottle of milk is 2e I ...
