Economics Essay 73: Perfect Competition and Efficiency

Explain how perfect competition should lead to outcomes which are both productively and allocatively efficient.

Perfect competition is a market structure characterized by a large number of buyers and sellers, homogeneous products, free entry and exit, perfect information, and no market power. In such a competitive market, the forces of supply and demand interact freely, leading to outcomes that are both productively and allocatively efficient.

1. Productive Efficiency: Productive efficiency occurs when goods and services are produced at the lowest possible cost. In perfect competition, firms face intense competition, which drives them to minimize their costs of production. This is achieved through various mechanisms:

a. Price competition: In perfect competition, all firms sell homogeneous products at a market-determined price. Firms have no control over the price and must accept it as given. To stay competitive, firms strive to minimize their costs and increase their efficiency to ensure profitability. This drives firms to adopt cost-saving technologies, improve production processes, and achieve economies of scale, resulting in productive efficiency.

b. Entry and exit: Perfect competition allows for free entry and exit of firms in the market. If a firm is unable to operate efficiently and incur losses in the long run, it can exit the market. On the other hand, if a firm identifies an opportunity for profit, it can enter the market. This constant entry and exit mechanism ensure that only efficient firms survive in the long run, leading to overall productive efficiency in the market.

2. Allocative Efficiency: Allocative efficiency occurs when resources are allocated in a way that maximizes social welfare, where the marginal benefit of consuming a good equals its marginal cost of production. In perfect competition, allocative efficiency is achieved through the following mechanisms:

a. Price as a signaling mechanism: In a perfectly competitive market, the price of a product is determined by the interaction of demand and supply. The price acts as a signal for both consumers and producers. When demand exceeds supply, prices rise, signaling producers to increase production. Conversely, when supply exceeds demand, prices fall, signaling producers to reduce production. This process ensures that resources are allocated to the production of goods and services that are in high demand, leading to allocative efficiency.

b. Zero economic profit in the long run: In the long run, firms in perfect competition earn only normal profits, where total revenue equals total cost. This implies that firms are operating at the point where marginal cost equals price. At this equilibrium, resources are allocated efficiently, as any reallocation would lead to either higher costs or lower revenues. Therefore, perfect competition ensures that resources are allocated in a way that maximizes social welfare.

In summary, perfect competition leads to outcomes that are both productively and allocatively efficient. Productive efficiency is achieved through cost minimization and the entry and exit of firms, while allocative efficiency is achieved through the price mechanism and zero economic profit in the long run. These characteristics of perfect competition ensure that resources are allocated optimally and goods and services are produced at the lowest possible cost, benefiting both consumers and society as a whole.

Economics Essay 52: Evaluation Monopolistic Competition

 To what extent is monopolistic competition a more desirable market structure than perfect competition? 

Differentiation between Monopolistic Competition and Perfect Competition:

Monopolistic Competition: Monopolistic competition is a market structure characterized by a large number of firms that produce similar but differentiated products. Each firm has some degree of market power, allowing them to differentiate their products through branding, quality, features, or other attributes. Firms in monopolistic competition have control over pricing decisions and face a downward-sloping demand curve due to product differentiation.

Perfect Competition: Perfect competition is a market structure where there are numerous small firms that produce identical products. In perfect competition, firms are price takers, meaning they have no control over prices and must accept the prevailing market price. Firms in perfect competition face a horizontal demand curve as their products are perfect substitutes for each other.

Evaluation of Desirability:

Monopolistic Competition: Advantages:

1. Product Differentiation: Monopolistic competition provides a wide variety of products, allowing consumers to choose based on their preferences and tastes. This product diversity enhances consumer welfare and satisfaction.
2. Innovation and Creativity: The competitive nature of monopolistic competition encourages firms to innovate, differentiate their products, and seek unique features or branding to attract customers. This drive for differentiation can lead to increased product innovation and consumer benefits.
3. Potential for Higher Profits: In the short run, firms in monopolistic competition can earn economic profits due to their market power and ability to set prices above costs. This potential for higher profits can incentivize firms to invest in research and development, leading to further innovation.

Disadvantages:

1. Inefficiency: Monopolistic competition can be less efficient compared to perfect competition. Firms in monopolistic competition may have excess capacity and duplication of efforts due to product differentiation, resulting in higher costs and potential inefficiencies.
2. Higher Prices: Firms in monopolistic competition may have pricing power, which can lead to higher prices compared to perfect competition. These higher prices can reduce consumer welfare and affordability.
3. Limited Competition: Monopolistic competition can result in limited competition due to barriers to entry arising from the need for product differentiation. Limited competition can hinder market efficiency and restrict the benefits of vigorous price competition.

Perfect Competition: Advantages:

1. Allocative Efficiency: Perfect competition ensures that resources are allocated efficiently to meet consumer preferences. The market mechanism of supply and demand determines prices, leading to optimal allocation of resources.
2. Lower Prices: Firms in perfect competition have no pricing power, resulting in competitive prices that maximize consumer welfare and affordability.
3. Promotes Competition and Innovation: Perfect competition encourages firms to be efficient, innovate, and seek cost reductions to stay competitive in the market. This drive for efficiency and innovation benefits consumers and the overall economy.

Disadvantages:

1. Lack of Product Differentiation: Perfect competition involves homogeneous products, which can limit consumer choices and variety.
2. Limited Profits: Firms in perfect competition can only earn normal profits in the long run, as they are price takers and have limited control over their profit margins. This limitation may discourage firms from investing in research and development or pursuing long-term growth strategies.
3. Lack of Branding and Consumer Loyalty: Perfectly competitive markets focus on price as the primary differentiating factor, which may lead to less emphasis on branding and customer loyalty.

In conclusion, the desirability of monopolistic competition versus perfect competition depends on various factors and perspectives. Monopolistic competition offers advantages such as product diversity, potential for higher profits, and innovation. However, it also exhibits disadvantages such as inefficiency, higher prices, and limited competition. Perfect competition, on the other hand, promotes efficiency, lower prices, and competition but lacks product differentiation and may limit firm profits and investment in innovation. The choice between the two market structures depends on the specific context, industry

My perfect affair – how I’m getting away with it

Anonymous as told to Joan McFadden in The Guardian


Tell no one, put nothing in writing, pay in cash, don’t drink, and keep off the phone. How to have an affair for nine years and get away with it

Love and happiness are certainly important to me in my 20-year marriage to Stephen. They are also important to me in my nine-year affair with Michael. I didn’t have an affair lightly. I know people have affairs for all sorts of reasons and think ultimately that they have a goal in mind – the end of their marriage, a lasting new relationship or a complete change to what they see as a boring life.

I’m none of these things. I want no drama disrupting my family. I want to stay happily married and carry on my affair and I never, ever want anyone else to know, so I have every detail planned and covered. My husband doesn’t suspect, my sisters and my best friends have no idea and I make sure there’s no evidence at all that can trip me up.

I didn’t start an affair because I’m lacking anything with Stephen. He’s a brilliant dad and funny, intelligent, fit and attractive. We’ve always made an effort to keep things fresh – of course you get bogged down in daily life, but we go out for dinner by ourselves or have a day off when we pack the kids off to school and go back to bed for a few hours. We also do a lot as a family, as well as socialising with friends and enjoying a variety of hobbies, so being organised is vital and, like many working mothers, I keep a meticulous diary to make sure everyone is in the right place at the right time.


I also have a diary in my head of my times with Michael, but I never put anything in writing. No love missives – texts are about the families getting together – and any emails are work related because we work in the same field. Stephen was friends with Michael first, having met him at a school event when our youngest child was just starting. He couldn’t believe we hadn’t met professionally and soon introduced us. He’s completely different from Stephen, who is very forthright, enthusiastic and go-getting while Michael is dreamy and creative, but with an incisive sense of humour and very witty, so they get on well.

I was quite shaken when I started to find Michael attractive. I’m not stupid enough to think you can go through life fancying only one person, but I’d kept any previous little crushes firmly in my head. Stephen is quite a flirt himself and the odd little bit of jealousy never did me any harm, and tended to respark my interest in my husband.

This was different. For the first time since we got married, I could imagine myself having an affair and at first it made me uncomfortable. I started plotting how we could do it and never get found out, and almost convinced myself that I was just being academic about it. Then we all got quite drunk at a party and Michael and I really started flirting. I thought life would go back to normal the next day and it did in front of Stephen and Jane, but we had a completely different relationship when we were alone.

We started talking dirty. At first it was just a little edgy – do you still fancy Stephen/Jane? Ever been unfaithful? Ever thought of it? It got more and more explicit and I couldn’t get him out of my mind. But I got a bad shock when he sent me a filthy text one night. I was sure he was drunk as it was short but very graphic. At that point my conscience was almost clear as we’d done nothing but talk, so I said, “Oh my God, Stephen – Michael’s just sent me a text that’s meant for Jane!”

Stephen thought it was hilarious and I texted back and said, “Isn’t this for Jane? Stephen says lucky her!”

Stephen teased him about it for ages but the next time I was alone with him I was furious and told him never to do something so stupid again. He said he thought I fancied him and I said very calmly that I did, but I wouldn’t risk my marriage or kids for anyone. It took another six months of discussion and planning before the affair started. We agreed that it was to be an added extra to an already strong friendship, but organised calmly and dispassionately, so no one would suspect.

By the time we slept together, we were both in a total state and it was a complete disaster. He’d been to the first day of a conference – I arrived that afternoon and checked into the same hotel. We had three hours in the late afternoon till his flight home and despite all our talk about being calm and dispassionate we were both unbelievably nervous. We were like two teenagers, and not in a good way.

For months I’d been totally turned on every time we were anywhere close to each other, but not now. The sex was clumsy and painful and a couple of times I wondered what the hell I was doing. He had his own worries – it was over far too soon and I felt dissatisfied as well as guilty – and he clearly felt the same. We had another go before he had to rush for his plane and it was just as bad. He said he would text me and I snapped at him not to – had he forgotten all we agreed? Stephen phoned later and in the midst of the chat about the kids asked if Michael was at the conference so I said he’d popped in before he left.

Coming home the next night was hellish. I was sure Stephen could tell I’d had sex with someone else but he was the same as ever and I was pathetically pleased that I was able to enjoy sex with him as normal. It was another two days before I saw Michael again and I was desperate to phone him, despite my rules, though I managed not to. He looked so miserable I was instantly irritated, convinced Jane would have guessed something was up. I was tempted to suggest we just forget it but I didn’t want to make him even more upset so I was reassuring and said we’d sort something out.


We went away for a week’s holiday and I did a lot of thinking. I decided that nerves had made the sex awkward, and once we got over the hump – so to speak – we’d be fine, so I deliberately made plans. Stephen took the kids to the cinema that weekend. I phoned their house, telling Jane I had mislaid papers from the conference and asking if Michael could bring me his so I could copy them. I read one of Stephen’s porn mags to get me in the mood, opened the front door and literally dragged him into the toilet, where we had exactly the sort of sex I’d imagined.

That was the last risk I took. I’m sure no one suspects we’re having an affair. We meet as lovers about twice a month, which probably does keep the magic and anticipation going, but I’m endlessly careful; I do worry about CCTV now as it’s everywhere. We usually meet at a conference hotel or at the airport and I might say to Stephen that I bumped into Michael and had a coffee with him, though I obviously won’t tell him that was after lunch and before sex. We’ve managed to resist that temptation to tell others by talking to each other instead. There are no romantic letters, emails or texts – and because we have fairly constant contact, there’s none of that terrible panic that illicit lovers seem to have about when the next encounter will be.

This care is also my safety net should Michael ever want more. He says he still loves Jane but if he decides otherwise I would just deny everything and there’s no proof. Not a note, credit card bill or hotel receipt – everything is paid by cash – so I’d just walk away.

I wouldn’t be friends with Jane if I didn’t want the smokescreen that provides – we’re too different and there’s a slightly snobbish side to her that irks me, but a monthly coffee or occasional girls’ night makes it seem that we have a separate friendship and so she’s much less likely to suspect anything. She’s even said that I’m good for Michael as he doesn’t have sisters so it’s nice to see him have a friendship with a woman.

I love both men, I’m harming no one and have no intention of doing so. I know we’re being greedy but it’s not affecting anyone else badly. If anything, it enhances my sex life with Stephen and when you’ve got two men seeing you naked you certainly keep yourself fit. I want everything to continue as it is, whereas many people having affairs want something to change, usually other relationships, so they can be together all the time. Strange as it may seem, my biggest worry is that, years on, Michael may die first and I won’t be able to grieve properly, because although the close friendship is known and taken for granted, obviously the affair isn’t. In a matter of fact way, we also assume that, when we’re much older, if our partners die we’ll end up together almost by default. Like everyone else, I’m aiming to live happily ever after, but with both men as part of my life. The only way to make that feasible is to keep everything as tidy as possible.

Perhaps we don’t want to explore the premise that for most people it’s not fidelity and love that keeps them constant to their partner, but fear of potential messiness should they be discovered. How many people, no matter how satisfied with their sex lives and happy with their partners, would say “no thank you” to an explosive sexual encounter if it was guaranteed that they’d never be found out? Domesticity doesn’t do it for everyone long term, no matter how much we’d like it to and although that’s apparent in male behaviour over the centuries now that women are on a par with men, surely this means such potential restlessness applies equally to both sexes?

It takes a very brave person to give an honest response, but, before judging me, ask yourself just one question – what’s stopping you from doing exactly the same?

I'm an everythingist – craving new experiences, but unwilling to put the work in

Everythingism is the deadly combination of perfectionism plus narcissism plus utter laziness – which explains why I haven't read Crime and Punishment

Crime and Punishment: details available on Wikipedia. Photograph: CBW/Alamy

When I was pregnant, someone told me that she read Dostoevsky novels to her baby, both in the womb and after he was born. Apparently, at about two months old, he would respond with delight every time he heard the character names he had heard so many times in utero.

Massively annoyed by this insufferable woman and her competitive wankery, I resolved to go home and do exactly the same thing. Only I had never read any Dostoevsky, and wasn't sure that I could be arsed, in my seventh month of gestation, to begin a literary journey into desperate horse-flogging Russians and Siberian internment camps. So I went straight to the Wikipedia page for Crime and Punishment and skipped to the list of character names instead.

"Raskolnikov! Svidrigailov! Dunechka!" I barked at my foetus for no discernible reason, the laptop balanced precariously on my bump, while my internal smugometer wavered somewhere between pride and existential despair. A little like the characters in the books. Perhaps.

It was some time after this that I took a long, soft look at my slapdash, half-arsed approach to life, and realised that I am an everythingist. This is a word I have invented to describe the sort of person who is greedy for the benefit of all new experiences, but unwilling to put the work in to fully commit to any of them. An everythingist leaves no experiential stone unturned, which means doing absolutely everything by halves. It is the deadly combination of perfectionism plus narcissism plus utter laziness. It will get you nowhere in the end. Halfway there at best. Every time an everythingist's mother opens her mouth, the words "oh just bloody well get on with it" come out.

Here's how to tell if you, too, are an everythingist. Do you clutch your phone in your hand at all times, like a beacon against the cold, a magic talisman with its promise of otherness, betterness, of more attractive people desirous of your company elsewhere? Does it ensure you are unable to quite go with a plan or be in the moment because of all the other plans and moments where you might be, cheating on yourself with your other selves? Does your phone give you FOMO (AKA fear of missing out) for the party you're not at, even when you're at it? Did the news that Prism could be spying on all of our data give you a giddy rush when you thought that one of the lockdown powergeeks might be looking in and realising that you – you! – are the chosen one? Do you tend to fall asleep in your clothes, just in case the revolution should begin outside your bedroom window in the night?

Do you, like me, think that fairytale endings will magically happen to your life – ie, you will fall in deep rewarding love and raise daughters with Rapunzel hair in a beautiful Welsh farmhouse one day, writing novels on a typewriter, milking your nanny goats at dawn? Of course, this all will have to happen magically as you absolutely refuse to give up nightclubs and the closest you have come to milking your nanny goats at dawn was all a case of mistaken identity and that restraining order for going within a 40-metre ring of the late-night Turkish greengrocers is a gross infringement on your civil liberties, which you will sort out as soon as you find the bit of paper they wrote it on.

The everythingist can't be tied down by a job and so they work freelance (ie are self-unemployed). They don't want to be restricted by narrow labels like straight or gay because they believe their sexuality to be a fluid concept (i.e. they keep getting dumped). They are breathlessly addicted to their youth, despite being 12 years older than their parents were when they had them; can't read a book to the end because they've already started two more; and they need to know, at all times, that they could, in theory, if they wanted to, at any point, run away to Rio de Janeiro.

The everythingist works from home, revelling in their freedom to go for a walk in the sunshine while other sad jobsworthy losers are stuck at their desks with not so much as a freelancer's liedown to look forward to. The everythingist has been planning this walk in the sunshine for 17 days now, having been quite distracted by all the freelancer's liedowns that it is their right and freedom to enjoy. In their lunch hour. I mean, why not? It's not as if there's any lunch.

If you are not an everythingist, and you're one of those people who gets stuff done and gets over it – I realise now that you have the greatest freedom of all. The freedom to finish things, and not have all your half-read books, half-written books and half-experienced experiences clanking around your neck like shells. I can only apologise for how I used to giggle at you for being boring and keeping lists and being on time while I dashed over half an hour late to meet you, hopes and dreams blinding my eyes so that I couldn't read a bus timetable. I'm so sorry now. For everything.

How to let your kids fail

by Elizabeth Hartley-Brewer in The Times

Don't confuse your success with your children's. Separate yourself from your children. Neither their failures nor their successes are yours. Ask yourself why either matter so much to you.

Don't set unrealistic standards. Allow your children to set their own achievable goals and move on to the next one when they are ready.

Don't punich failure and see it as shameful; this can lead to lying, cheating, defiance, self-doubt and anxiety.

Don't generalise from any setback or mistake. It is not helpful to say, "You'll never be successful in life if you carry on skimping ...."

Don't reject them if they disappoint you or adore them if they succeed. Love them for who they are, not for what they can do.

Don't demand perpetual progress so that no success ever seems good enough. This could lead to anxious perfectionism and burnout.
