  1. Re:Kind of innevitable and entirely reasonable on Canada Revenue Agency To Tax BitCoin Transactions · · Score: 2

    For an economy, efficiency isn't just about doing a particular thing with fewer resources. You can also be inefficient by doing the wrong things. Think of the badly organized communist state which manufactures - very efficiently - twice as many left shoes as right. Or more plausible government that piles its country's resources in to terrorism prevention, whilst ignoring road safety.

    - If the tax money collected by the government is spent on a program which yields a higher return (by increasing the nation's productivity) than if the money had remained in private hands, then tax evasion is stealing from other taxpayers.

    It isn't quite as simple as that. Suppose you're a better carpenter than me and I'm a better gardner than you. And suppose there's some carpentry I want I could do myself in 10 hours, and you could do in 8. And suppose there's some gardening you want you could do in 10 hours and I could do in 8. The logical thing - the efficient thing - is to swap tasks and do each others. We both get what we wanted with less effort. Now suppose there's a 25% or more tax - for every 8 hours work you do, you have to do another 2 or more effectively for the government. This swap is no longer in our interests, and we're better off doing the work ourselves even though its less efficient. So, added to the cost to individuals of taking away some of what they consume to provide government services, there's an additional cost caused by reduced efficiency. Considering efficiency grounds only, the public program needs to provide higher economic welfare than the amount lost to the individuals who are taxed, plus the amount used up administering the tax, plus the efficiency loss caused by the distortion of economic decision making.

    Of course, as any basic economics course will tell you, this effect can also be used to increase efficiency where purely private decision making comes out with poor results. Pollution is the classic case. And its also worth noting that the same effect occurs with monopoly prices.

    But there's more to an economy than being efficient. Its purpose is to promote the economic welfare of its citizens. In the political view of most people, this includes some (widely varying) amount of redistribution, too. And if you take maximum overall economic welfare as the goal (which is tricky, because adding welfare across people is rather conceptually difficult), and notice that giving a little to a poor person produces a much bigger increase in his welfare than giving a little to a rich person, the logical outcome would involve quite a lot of this redistribution.

    I think some variation between people has to be allowed for (not to mention locating households with several occupants who travel to different places). There are lot of differences between large cities and small towns/villages other than house size - air quality, noise levels, environment, leisure activities, crime levels and so on. Some people love the busy-ness, noise, access to shops, vibrancy and general shittiness of cities, whereas others hate those things. Those numbers aren't going to be the same for everybody - and some commuters will spend some chunk of their commuting time on foot, which makes a difference.

    It's a lot better with adequate transport and well chosen locations. My first commute from a village involved a five minute walk, 26 minutes on a train to travel 30 miles (to London), then another five minute walk. Many people travel for much longer than that just inside the city. London is a bit different to most US cities, though.....most journeys to central London are by public transport, and it's almost totally inaccessible by car for most commuters (outer parts are different, though). (There also aren't actually enough homes in London for everyone who works there to live there). And central London salaries can be 40% greater (and a lot more for some people).

    Why does population come into it? Does it really matter how many people there are in a country? Especially if a great deal of them are still barely scratching at the earth.

    Does it really matter what political boundaries have been drawn around a person? Does a subsistence farming hermit in the US have a moral right to emit more greenhouse gases and particulates than a subsistence farming hermit in Montserrat, or Myanmar, or Uganda? Does person X have more moral right to impose costs on others via pollution than person Y merely because of his habitual location? It's hard to imagine a reason why.

    Would people demand emission cutbacks from a country populated by a single cow, just because that country's methane output per capita was the highest in the world?

    If the country has no population then I can't help thinking demanding cutbacks from the local wildlife would be ridiculous. Besides, it's consumption that matters, not production, so if this magical cow were to export its own milk to import grass then the pollution burden is being caused by its customers.

    Correct me if I'm wrong but, economically speaking, wouldn't it be far better to measure pollution in relation to GDP (or another measure of national productivity)? A more "green" country is surely one which can manage to eke out more productivity with the same amount of pollution (or the same productivity while being less polluting). It surely shouldn't matter (in terms of ranking) if they manage that with solar power, people power, robots, or whatever?

    A more efficient economy would product more stuff with less cost (and pollution is still a cost, even if there's often no transfer of money to represent it). That more efficient economy could provide more consumption to its participants for the same amount of pollution rights. But I don't see why person X consuming more than person Y would give person X more right to impose pollution costs on others than person Y. Aside from being a destructive and inequitable feedback loop that entrenches the current world balance of resource use, it makes no sense. There's nothing inherent about person X that makes him 'worth' more pollution and deserving of more of its products. He's just a random human, no more or less than person Y.

    And FWIW, I have no idea which country would "win" using such a measure.

    Why do countries matter? Giving everyone equal rights to pollute would, of course, mean those rights would have to be traded (because most people don't do the polluting themselves, they do it via trade (ie, buying stuff from people who do it for them)). The outcome would be that most especially high consumers (but almost everyone to some degree) in the industrialized world would have to pay to buy pollution rights from low consumers outside it. There'd be very strong incentives to produce more efficiently, very strong incentives to substitue certain kinds of consumption for other kinds, and a large transfer of consumption to poorer parts of the world. In some ways it'd be a sort of global basic income. We'd all suffer lower pollution costs, but most people on slashdot (including me) would be a lot poorer. For that reason - self interest - neither I, nor most people here, nor our politicians are going to push for this. But don't pretend there's a moral excuse. There isn't.

    It's pretty much the same with and without the gold standard. There is no such thing as an absolute amount of 'value'. Money is a relative thing: it relates an amount of apples to an amount of oranges, an amount of labour to an amount of land, an amount of labour to an amount of gold, an amount of apples now to an amount of apples in six months. Given a random unknown currency you know nothing about, the number X$1 gives you no information at all. You need to know the price of at least one thing to know if that's a lot or a little. That's still true if the currency uses the gold standard. All the gold standard does is say that the price of gold a year from now (or any other time) will be the same as it is now, assuming no political upheaval that abolishes it. All of the other prices can still vary freely, relative to each other and to gold. It doesn't fix the price of labour to the price of apples, or of land to oranges, or anything actually important. It just keeps the relationship between an arbitrarily chosen unit and a not very useful product constant over time.

    Gold standard advocates like it because it ties the central bank's hands with respect to monetary policy. It does nothing at all to give a currency a fixed value because gold is mostly not what people want to consume.

    High public debt drains away valuable resources faster than low public debt

    How does it do that? Where do the resources go? Yes, in some cases countries (eg, Greece, Italy or Portugal) are losing huge proportions of their most qualified workers, but that's because of the recession rather than the debt itself. There's an argument that high debt causes high taxes which causes economic distortions which reduces activity, but the reduced activity isn't caused by resources being 'drained away', it's caused by those resources sitting there and not being used.

    Given the same amount of initial resource, a country with high public debt will have smaller chances for recovery

    That's an assertion. Do you have reasons? And why specifically public debt, and not total debt?

    It may be better to distinguish between foreign debt (public and private) and domestic debt. Greece had a lot of public debt borrowed from foreigners. Spain had little public debt, but lots of private debt borrowed from foreigners. When that debt was building up there was more being consumed in those countries than was produced.....the borrowing of money from abroad allowed this to happen, because without it there'd have been no euros left in those countries, they'd have all been used to pay for imports. Now they have to pay back their debts, and to do that they need to reverse those flows: make more than they consume, receive an inflow of euros in exchange for them, and send them back out again to pay the debts. This isn't happening, but not because of a lack of resources, or because of any sort of draining away. They have lots of unused resources. It's working because the control system of their economy - markets, prices, contracts, banks, laws and so on - can't do the right thing to organize those resources in to productive use. And, of course, one reason for that is because there's no exchange rate there to create across-the-board price reductions for their domestic inputs and outputs.....
