    Hmm, how much does some notion of market value matter now compared to, say, forty years ago? People didn't change employer so much. I suspect that pay forty years ago was more likely to follow bureaucratic formulae - this much for three years service, that much for a going up a 'grade' because it's your turn - rather than be related to how much you could achieve and what you'd be worth in the marketplace. If that's true we might expect a 'flattening' of pay compared to age - with better younger workers outpacing less skillful older workers more quickly, but finding that their pay doesn't keep going up just because they've got, say, 12 years experience of writing software instead of eight.

    Ultimately it's those in poor countries that must bring themselves out of poverty, by developing their political systems and economies (markets, finance, industries, infrastructure businesses themselves, enforceability of contracts etc.). Many have huge problems with corruption. In many it takes dozens of official steps to do something as simple as set up a business as a legal entity simply because more steps means more bribes. In some, official property rights to land are near impossible to get, harming stability for businesses and making it impossible to obtain mortgages. Electricity is unreliable or rationed (unless you live next door to an important politician), which hardly makes running a business easier because they all need their own generators and fuel. In some places you have to be on a waiting list for years to get a phone line. Now put all of this together and imagine trying to run a business.

    Also, it's not always true that the admin charges and amount taken by the ticketing-system supplier are equal.

The venue may set the admin charge to be the same, but isn't required to do so.


    Oh, and sometimes suppliers will have very long contracts with venues which prohibit the sale of tickets through any other system (and 'system' may include the software running on the computers in the venue's own box office - any decent system will integrate the two, so that buyers through any sales channel can choose a seat out of all of those available).

    There is no reason that numbers need to be stored - even for subscriptions.


    There ARE reasons to store numbers with the current system - and especially there are reasons to store enough to be able to return money. Consider, for example, an event which is cancelled with a few tens of thousands of tickets sold. Are you going to call all of the ticketholders and ask for the card number? What will you do when someone spoofs those calls? What if you receive an order which you believe to be fraudulent (because you've discovered a connection with other fraudulent orders, for example)? If you have the PAN you can get a message to the issuer who can suspend the card until it's been checked with the holder. If not, you can't. And storing at least hashes of a card number can be useful for detecting the suspicious reuse of a card across multiple transactions, and for refusing cards for which you've received questionable chargebacks in the past.


    You are, however, right that it's not actually necessary, but the card industry needs to get its act together. Why is the number which identifies the card so valuable?

    I think you may have missed the point of combined heat and power. The idea is to generate electricity and heat simultaneously in the winter instead of just heat. As you no doubt know, power stations throw away two-thirds of the energy going in in the form of heat released in to the environment (AFAIK there are no cases in the UK where this heat is pumped in to homes). Combined heat and power in a home can be MORE efficient overall than a power station even if it produces less electricity from the input because it can use a large amount of what would have been waste heat.

    Does the US need to do more to reduce its (carbon) emissions? Hell yes. But so does everyone else.
    Make it simple. Everyone...reduce your individual countries emissions by x% in y years. No breaks, no 'trading', no excuses. X%.


    This is a bad idea, for two reasons.


    Firstly, trading is essential to both finding new ways to cut emissions and to cutting emissions efficiently (which in turns allows more cuts because they are more politically acceptable). It helps cut emissions more efficiently because some industries and countries have easier routes to cuts than others. If one country can cut more than their 'fair share' cheaply and sell their credits to another that can only do so expensively for an intermediate price then both countries gain, the same global reduction occurs and people's lives are better because there is more economic output. It helps find new ways to cut emissions by making finding them pay. If you, as a company, only need to go below some bar and no more then you'll invest and research so as to just about meet it. If you can sell credits you don't need (or have to buy expensive credits) then you suddenly have an incentive to be inventive - you can increase your profits by cutting by more than your 'fair share' demands.


    Secondly, any regime which demands differing carbon allowances for different people is not going to survive politically in the long term. If you say to a chinese person 'you can only emit one tenth of what I can emit' and, as a result, that person suffers drastically reduced economic well-being, then countries with lower quotas will sooner or later either fail to agree to quotas, quietly cheat on quotas more than otherwise or just outright tell you to fuck off. Parity for carbon allowances worldwide, whilst rather frightening for the rich, is an eventual and inevitable consequence of running such a scheme because anything else is effectively saying 'we're more entitled to this earth than you are'.

  16. Re:Interlectual Property is not scarce on US Opposes G8 Climate Proposals · · Score: 3, Interesting

    That is why appeals to non-scarcity cannot differentiate IP from other property.


    You're joking, right??? The term this thread is searching for is 'non-rival' ( http://en.wikipedia.org/wiki/Rivalry_(economics) ). Apples are rivalrous goods. If I eat an apple I reduce the amount of apple left for everyone else. Housing services (think 'house-months') are, too. If I live in a house for a month, I reduce the amount of housing left for everyone else for that month. A musical recording, or a piece of software, is non-rival. If I listen to (or copy) some country music it doesn't - regrettably - reduce the amount of country music left in the world for everyone else.


    That is the difference, and is why intellectual property is fundamentally different. No free market can produce an optimal outcome for an economy containing non-rival goods (see my other post on the first theorem of welfare economics). With no IP protection there's too little incentive to generate IP. With IP protection people who might benefit from the IP but not by enough to pay the market price cannot make use of it, and this can add up to a lot of lost economic welfare (especially for those in poorer countries - consider AIDS drugs). There's a second-best maxima at some level of IP protection, but it isn't as much as the perfect economic choices (all IP which costs less to produce than the total benefits is produced, and anyone who can benefit from it uses it freely).

  17. Re:sanctions are inevitable on US Opposes G8 Climate Proposals · · Score: 1

    The only problem with a pure free market is that it acts under the assumption that what makes the best business sense will be inherently good for everyone.


    If you'll excuse me being pedantic, markets don't assume anything as they're mechanisms and don't have brains. What's important are the people involved in them and the effect the mechanism has on their behaviour. The lay-belief in 'free markets' (without, of course, any adequate definition of 'free') has it's more rigorous counterpart in the first theorem of welfare economics. This shows that the economic outcome of a whole free-market economy is 'efficient' (see http://en.wikipedia.org/wiki/Pareto_efficiency , but in summary it means no-one can be made better off without making someone else worse off) and distribution of wealth neutral if certain conditions are met. These include:
    • There are no missing markets, for ANYTHING in limited supply which affects human economic welfare. As others have already said this would require a market in pollution rights, with supply ultimately limited by the capacity of the earth to cope with every pollutant. (This implication of 'no missing markets' is sometimes made a separate assumption - an assumption of no externalities; see http://en.wikipedia.org/wiki/Externalities . Whether you consider this to be a 'missing market' or not, this IS a requirement of the theory).
    • Everyone has all the same information.
    • There are no monopolies, (or industries which are 'natural monopolies').
    • There are no 'public goods': http://en.wikipedia.org/wiki/Public_good . This means that for the theorem to work you have to assume the non-existence of literature, software, street-lighting, policing, defence and so on.


    This theorem is essentially the entire theoretical basis for a 'free market', but the assumptions are ridiculous. It's an excellent starting point, practically and theoretically, but the economic argument for pure free markets falls massively short of what some lay-economists think it supports. To come to any sensible conclusion about free markets you REALLY have to understand the first theorem of welfare economics. Unfortunately, the wikipedia article (http://en.wikipedia.org/wiki/First_fundamental_th eorem_of_welfare_economics) is awful and I can't find any good alternatives, so you may have to resort to a library...
