YOU sir are amazing (+rep).

One question though: With regards to price discrimination, I find it difficult to evaluate why it won't achieve allocative efficiency.
Also, you've listed the difference between 1st, 2nd and 3rd degree but can you please give real life exams where it happens in pratice? 3rd degree is easy to understand because it's between different countries; 2nd is like different bus fares for students and pensioners, right? But then what is 1st degree?
Thank you so much

Because price doesn't equal marginal cost.

1st is where each consumer is charged the maximum they are willing to pay, the closest you can get to it is like a sealed bid or an auction but it's not very realistic.

2nd Is where a firm will profit maximise, and then sell what is left over where AR=MC, so this could be last minute flights, you are selling it to two different groups at different time periods.

3rd is where two portions of the market have different elasticities of demand, for example peak and off peak train tickets, or telephone calls. Firms then exploit this difference in elasticity by profit maximising in each market separately, because the revenue curves are different but the cost curves are constant the firm can make a higher profit.

What is carbon trading? Is it just selling pollution permits?

I think price discrimination may come up, haven't seen it in a while if I remember correctly.

Yes, it's basically the market that is created due to the introduction of pollution permits. It is good to use specific examples like that instead of just saying "pollution permits", shows you have done your research.

an example of first degree is like an auction, or when you go to a car boot sale (you haggle - you get low prices)

Why is allocative efficiency not achieved with price discrimination? Thanks for the notes

Oh hahha just seen the reply above, sorry

I'm at college, and they are doing building work with massive drills in the "quiet area" of the library... resulting in the best spot to do work at the computers with noisy AS kiddies who have finished their exams chatting around me.

I'm glad this is one of the few pm exams I have

Anyone think that cost benefit analysis essay question will come up? It came up once if I can remember correctly in the jan 2010 paper. Good Luck everyone! You'll all do well!

A contestable market is costless to enter or exit, right?

All firms have costs on entering or exiting an industry. There are no sunk costs when entering a contestable market, which means that the firms would recover all costs when entering the contestable industry.

good luck everyone

The exam was quite good, I'm glad poverty came up. would National minimum wage be considered a supply side policy?

[Stabilopink]

Did anyone do the small and large firms essay question? I have no idea whether what I wrote was relevant!
