CET/Free trade
Therefore tariffs are OK to protect farmers, yes?
But, hang on, tariffs against EU farmers restrict free trade and therefore are against the greater good...aren't they?
So how can tariffs be good and bad?

The Bank of England should seek to deliberately increase inflation!
The reasoning behind this would be to ensure that there were negative real interest rates.
If the Bank of England commits itself to producing significant inflation then real interest rates could become negative.
Thus people might borrow money (at 0% interest) and repay in their (devalued) pounds.
This would give people a significant incentive to borrow and spend.
A little more inflation might be preferable to rising unemployment or a series of fiscal measures that pile on debt bequeathed to future generations.
The idea of negative interest rates may strike some people as absurd, the concoction of some impractical theorist. Perhaps it is. But remember this: Early mathematicians thought that the idea of negative numbers was absurd. Today, these numbers are commonplace. Even children can be taught that some problems (such as 2x + 6 = 0) have no solution unless you are ready to invoke negative numbers.Specific tax
From 6.00 pm on 22nd April 2009, tobacco duty will increase by 2 per cent. The rates will be:
| Product | Duty | Effect of tax* on typical item (increase in pence) | Typical unit |
|---|---|---|---|
| Cigarettes | 24 per cent of the retail price plus £114.31 per thousand cigarettes | 7p | packet of 20 |
| Cigars | £173.13 per kilogram | 3p | packet of 5 |
| Hand-rolling tobacco | £124.45 per kilogram | 7p | 25g |
| Other smoking tobacco and chewing tobacco | £76.12 per kilogram | 4p | 25g of pipe tobacco |
* Tax refers to duty, plus VAT
This increases tobacco duty in line with inflation.
Here's a diagram showing tobacco tax.
The problem is that the cigarettes in my local tobacconist went up by the 7p i.e. the full amount of tax. This means the price rose by ALL the tax.
Does this mean that the demand is perfectly inelastic?
I think not.
Try drawing the diagram with the price rising by 7p i.e. the full amount of tax.
Then consider beer.
From Thursday 23 April 2009, alcohol duty rates will increase by 2 per cent above the rate of inflation.
Alcohol duties will increase by 2 per cent above the rate of inflation in each of the next four years.
| Product | Effect of tax* on typical item | Typical unit |
|---|---|---|
| Beer (4.2% abv) | 1p | pint of beer |
| Wine | 4p | 75cl bottle |
| Sparkling wine | 5p | 75cl bottle |
| Spirits (37.5% abv) | 13p | 70cl bottle |
| Spirits-based ready to drink | 1p | 275ml bottle |
| Cider and perry | 1p | litre |
* Tax refers to duty, plus VAT
Beer in my local went up by 1p - but demand is not perfectly inelastic.
So - what's happened?
Is the tax diagram rubbish?
Monday
Perfect competition
If they cost anything at all then that would be a barrier to entry!
Therefore as they cost nothing to produce all a firm has to do is produce (with no resources) an infinite number of goods and thus make an infinite profit.
Easy!
...or is it?
Comparative advantage
If a country has absolute advantage in both products which one do you specialise in?
Obviously the one where the gap between the maximum output of Country A and Country B is the greatest! If you draw it with two straight lines it's where there's the greatest distance.
That's what the IB Economics book says - so it must be right...mustn't it...?
Friday
Income elasticity of demand
This will have begative income elasticity of demand.
Thus as income falls, demand rises.
Equally as income rises, demand falls.
OK....
If the price of the inferior good rises then real income falls.
Thus as per above, more is demanded.
So, the price of inferior godos rises and so does demand. So all retailers who sell cheap and tacky goods have to do is...raise the price!
Yeah?
Now let's deal with some of the comments:
The rise in price depends on the reaction of demand?????

-
"If the price of the inferior good rises then real income falls.
Thus as per above, more is demanded."
Not agree,about inferior goods,we're not considering about the price
Income and demand
Income increases so the demand curve shifts to the right.
Now let's talk about elasticity.
One of the factors that affects elasticity is...income.
Therefore if income rises the SLOPE (gradient) of the demand curve changes...to the right.
Yeah?

Prostitutes, rice and Giffen goods.
"...show that in each case Giffen behavior is closely associated with poor consumers’ need to maintain subsistence consumption in the face of an increase in the price of a staple commodity. We then present evidence on the existence of Giffen behavior among extremely poor households in two provinces of China. In order to obtain an unbiased estimate of the key price elasticity, we conducted a field experiment in which we randomly subsidized households’ primary dietary staple (rice in Hunan province and wheat flour in Gansu province). Using consumption data gathered before, during and after the intervention, we find strong evidence of Giffen behavior with respect to rice in Hunan province."
This suggests that rice is a Giffen good, remember that a Giffen good is an extreme type of inferior good. The negative income effect of changes in price of a Giffen good is actual stronger than the substitution effect. This leads to its bizarre quality: when the price of a Giffen good rises, consumers actually buy more.
But what has this got to do with prostitution?
Quoting from the Prostitution index...
Prostitution is a unique labour market. Most people find it an extremely undesirable job, but on the high end, it can be quite lucrative and requires few skills (though a fair helping of unequally distributed natural endowments). These factors make the prostitution market exceptionally sensitive to large fluctuations in wealth and expectations.
The most interesting part is that the market is counter cyclical. In bad times more (and more attractive) women enter the market, but they have a higher reservation wage, so they charge more. Less attractive and even cheaper prostitutes may still be available, but for a variety of very good reasons, the customer will not desire the cheapest option, suggesting prostitution services can be classified as a Giffen good.
Does this mean that you can quote prostitutes as being a Giffen good in your Economics papers?
Thursday
Deflation
"The question is if we are in a situation which is deflation ,So the value of our money will decrease right? And what about our export it will cheaper or more expensive? "
Value of money falls - does this mean the exchange rate falls?
If the exchange rate falls will exports always be more expensive?
Will imports always be cheaper?
If your economy deflates but so do other economies also deflate, what happens?
Monday
The current recession
Thus the current fall in demand - for houses, for expensive goods etc - is merely a symptom, not a casue of the recession.
In which case....it makes no sense to prop the demand, treating the symptom, as long as the root cause of depression, a drop in profitability of production, due to misallocation of resources, is not fixed.
Sunday
Government should not regulate the banks!
It is widely believed that government intervention in industry can and does benefit consumers. But does regulation in practice have these desirableeffects?
Adam Smith certainly doubted its efficiency. To restrain people from entering into voluntary transactions ‘Is a manifest violation of that natural liberty which it is the proper business of law not to infringe but to support’. Nevertheless, he argued, ‘those exertions of the natural liberty of a few individuals which might endanger the security of the whole society, are, and ought to be, restrained by the laws of all governments . . . ’
He defended regulation in such cases in principle. But he objected to the practice. The legislature, he argued, is directed not by a view of the common good, but ‘the clamorous importunity of special interests’. His view was that whatever regulation could do in theory, in practice it usually benefits those regulated.
What does the evidence say?
A pioneer in this area is George Stigler. In a study of the electricity industry in the US, he found that regulation affected neither rates charged to customers nor profi ts earned for shareholders. In a study of the securities industry, he found that regulation governing the listing of new securities, presumably intended to protect the investor, had no significant effect on the returns to new shares as compared to ones already in the market.
A current UK example which should lead one to wonder about the benefits of regulation is food. When it was feared that eggs were likely to be harmful, and sales dropped, egg farmers were offered compensation – which was paid of course by a levy on consumers, who had just very plainly indicated in the market that they did not wish to support egg farmers!
In contrast, how was a different group, one not close or important to the regulators, treated?
Producers of non-pasteurised cheeses – a tiny group of farmers – and foreign cheese makers, were both threatened with having their products banned on health grounds before consumers had a chance to show if they were concerned!
Regulation has two vices. It restricts competition – all producers are compelled to behave in a similar way. And it restricts information – information has to go to the regulator, but not to the consumers who buy the product. Informed choice is not possible without information; and restricting competition means that there is less pressure to raise quality and lower cost.
For these reasons, regulation by government generally harms the consumer.
The best regulation is by competition combined with provision of information.
Low interest rates for economic recovery
We cut interest rates.This makes:
a. consumption rise
b. exchange rate fall (hot money) thus exports (multiplier) increase
c. savings down
d. investment up
e. imports (SPICED) now more expensive
f. demand up, unemployment down thus government spending down
g. more working, tax revenue up
h. mortgages down, discretionary spending up, more spending
Thus economic problems solved...aren't they?
But maybe we should RAISE interest rates?
When individuals choose to save part of their income, they free resources (that otherwise would have been used to make consumer goods) for the production of capital goods, i.e., plant equipment and machinery. And it is through investment in the production of more and better capital goods that the society creates the ability to make more and better consumer goods over time. Savings — and the wise investment of that savings by private businesses — is what is the source of a rising standard of living and real job opportunities in the long run.
Money is the medium of exchange — it is the means through which individuals are more able to exchange efficiently and economically with one another, including transferring savings from lenders to borrowers. Creating more money does not create more capital goods. Creating more money merely means that people have more pieces of paper with which to bid against each other in the attempt to acquire control over resources and commodities in the market. In other words, the ultimate result of a monetary expansion, in an attempt to stimulate trade and jobs, is a rise in prices in general in the economy, i.e., price inflation.But in the intermediary stage between the time the supply of money is increased and prices in general in the economy have increased, there often appears the illusion of economic prosperity and productive investment. But it is a transitory prosperity and an unstable investment climate. The prosperity lasts only as long as the inflationary process keeps selling-prices rising sooner and faster than cost-prices. Artificial profit margins are the source of the appearance of prosperity, but inevitably cost increases catch up with rising sales prices, and the boom ends.
Furthermore, the lower rates of interest resulting from the monetary expansion made available for lending purposes in the banking system, induce a large number of additional investment projects to be undertaken that turn out to be unsustainable in the long run. Investment requires savings, i.e., the availability of resources for the construction and maintenance over time of new and improved capital goods. But some of these investment projects will have been started purely on the basis of the illusion of greater savings created by the availability of more money for lending purposes. When the inflation finally ends or slows down, these investments will be found to lack the necessary savings base to sustain them. Hence, the investment boom produced by the monetary expansion has within it the seeds of a future investment recession.
So -should we raise interest rates - or drop them?Consumption is the main source of growth

Consumption (rather than savings/investment) is the source of economic growth. Surely that's obvious?
If we say that aggregate demand, shifts to the right and if there is spare capcity then the economy grows (rather than having demand pull inflation.)
What are the components of aggregate demand?
1. Consumption (C = f(Y))
2. Government spending
3. Investment
4. Net exports
If consumption increases then there will be an increase in investment (accelerator) and thus that injection in turn will create an increase in national income (multiplier) and thus growth.
UNLESS all the consumption is on imports, an increase in consumption will shift AD to the right (ceteris paribus).
If savings increase then demand falls (paradox of thrift). Thus if savings fall (consumption increases) there is growth.
Firms will not invest if they do not anticipate demand so without consumption, no investment.
Consumers consume and pay taxes. Taxes are revenue for government from which comes government spending. Without revenue (unless they borrow) governments cannot spend.
Thus consumption is needed.
Exports are to...people who consume.
Thus consumption is the main source of growth.
Tax cuts boost the economy

There are some who think this is incorrect.
Let's think about this though. The Laffer curve (see left) shows us that if you cut taxes this MIGHT lead to an increase in tax revenue - but it might not, especially if taxes are cut to zero!
But in some cases tax cuts will boost the economy.
Cut taxes....disposable income rises...spending increases...some of it on domestic goods. Indirect tax revenue rises. Employment rises owing to the increase in demand. More taxes received.
Maybe total tax revenue has fallen....but also maybe with lower taxes people work harder. Supply-side: people unemployed look for work.
Administration costs for unemployed, fall.
Benefits given out fall. Thus government spending falls so less need to borrow.
So tax cuts DO boost the economy because:
a. tax revenue may rise
b. unemployment costs fall
c. confidence and motivation improve. Productivity rises.
That's correct....isn't it?
Tax cuts make people work harder
Let's think about this.
Taxes cut, I keep more of my money earned. I am therefore more motivated UNLESS a) I have reached my target income and trade off work for leisure and also b) I am ABLE to cut down on my hours. (How many jobs let you do this?)
So either a) I will look for more work, more overtime (as the rewards have risen) or there will be no reaction other than short-term benefit.
Theerfore out of ten people, 7 may have no effect or only short-term, three will work more overtime.
Then there's the self-employed. They work hard anyway but cut their tax and the rewards are greater and so they may work even harder. Maybe they have more control over their work-life balance, maybe less.
If tax cuts don't make people work harder then why do companies offer higher wages to attract new workers? Why offer productivity bonuses?
Unemployment
Immigrants.
Get rid of them and you get rid of unemployment.
“Immigrants who come over here are willing to work for lower paid jobs and thus they create unemployment for local people.”
Yep - it's simple.
Immigrants take jobs that natives won't do - and these people then sign on for Job Seekers Allowance and a host of other benefits. Remove the immigrants and then the jobs would be there.
If I employ an immigrant then I pay the immigrant (or any labour, for that matter) less than the value of his/her output - how else would I make a profit? Thus the immigrant adds less to the demand than to the supply - thus excess supply, thus unemployment.
Immigrants pay tax, sure but that's out of their wages paid by me. So their disposable income PLUS the tax they pay is less than what they produce. Therefore supply > demand.
Having low unemployment and high immigration does not disprove this either. Where demand exceeds supply there is a need for labour up to the point where demand is met by supply. When this is met any extra labour will be unemployed. If part of that 'excess' is made up of immigrants then they are unemployed (but may not be claiming and so will not show in official statistics). Some of those working will be immigrants thus remove them and unemployed natives can take their jobs.
Is there anything wrong with the logic above?
Unemployment
Surely it is that easy isn't it?
Increase taxes, use the money to create jobs.
Bingo!
The end of unemployment except for those who are work-shy.
Or is it not that simple?
Free Trade

Can Britain follow a free trade policy? If so should this be unilateral?
We have free trade within Europe - but round Europe is the Common External Tariff.
How can this be the best option?
What about offering subsidies to our exporters?
The fact remains that regardless of whether a foreign producer is offering a better and cheaper product because of competitive efficiency or because of governmental support, that producer's product is offered to the British consumer at a lower price than the domestic seller is willing to offer it.
This cannot be good - can it?
For every job saved in the protected industry, other job opportunities are lost or fail to come into existence. Limiting imports means that the foreign producer earns fewer dollars than otherwise would have been the case. And with fewer earnings, the foreigners will buy fewer European exports, with a resulting loss of jobs in the exporting sectors of the economy.
At the same time, because European consumers must pay the higher prices charged by European producers, the standard of living of Europeans in general is lower than it could have been. This also means that the Euros that could have been saved if the less expensive foreign product had been bought are not available to European consumers to buy more of other products; as a consequence, jobs that would have come into existence to meet the demand for these other products never have a chance to materialize.
So we shouldn't have a Common External Tariff - and yet we do - why?
Current account deficit
MANY COMMENTATORS LAMENT that Britain is running a deficit in the current account of the balance of payments. Some worry particularly about our deficit in goods - what is called the visible balance. The second concern is always misplaced. The first is slightly more complicated. It is therefore better to deal with the simple matter first. International trade is basically of two types - trade in goods and trade in services. Exports of either generate foreign earnings, so, from that point of view, it does not matter what is exported. Indeed, it is perfectly normal as countries develop for them to produce and trade in services. International trade in services has been in recent years the fastest-growing part of such trade.
Some people worry because manufactured goods have become a smaller part of our output. That is a separate concern. But it is worth remarking that the arguments and evidence do not support the claim that it is intrinsically better to produce manufactured goods rather than services.
Given that the composition of exports does not matter, what about their total? Does it matter if we are exporting fewer goods and services than we are importing?
The best way to answer this question is to start with another How are we paying for these goods and services?
Some of them are paid for by our export earnings. Others are paid for in one of two ways - by running down our savings or by borrowing. Like an individual or a company, more can be spent than is earned, provided savings are reduced or borrowing increased. There are many circumstances where such action is perfectly sensible. There can be favourable investment opportunities, a temporary drop in income, or a chance to buy something more cheaply than usual. There is nothing wrong with borrowing; what matters is what it is for. If spending is wasteful, it is wasteful whether current income or borrowed funds are used.
The same is true for a country. If individual decisions by residents, whether firms or individuals, lead to a current account deficit, then a decision has been taken to spend more than income. If the funds being borrowed to finance that spending are used wisely, there is no problem. If they are not used wisely, then it is foolish spending, not the act of borrowing, that is the problem.
A striking example occurred in the United States. On average, that country ran a deficit on current account from the last quarter of the 19th century into the first decade of the 20th. It did so because there was a tremendous demand for funds to invest. Population, industry, and agriculture were all expanding westwards. The funds were lent from the residents of European countries, where the expected rate of return on investment was on average lower than in the United States. No one - at any rate, no one I know of - has claimed that the decline of the US set in with that foreign borrowing. It was used productively. The balance-of-payments deficit it engendered was in no way symptomatic of a problem.
Sometimes such deficits can be symptoms of problems (though not problems in themselves). For example, the symptom can be of 'excess demand'. Easy monetary policy may have over-stimulated demand, leading not just to rising prices, but also (as goods become harder to obtain or more expensive at home) to more purchases from abroad. If the exchange rate is floating, it will be driven down. And if it is pegged, there will be pressure to devalue.
Before summing up, one point remains. If a country is borrowing abroad, it is not necessarily increasing net overseas indebtedness. That may seem surprising - if a person borrows, his or her debts increase. But even in that case, if he or she has assets, they may be increasing in value more rapidly than the new debts. The same can be true of a country. The value of Britain's overseas assets has in recent years increased more rapidly than her overseas debts; increasing borrowing need not, and in this case did not, bring increased indebtedness.
Now to conclude.Overseas earnings are overseas earnings; it does not matter whether they come from sale of goods or sale of services. A current account deficit - more goods and services being bought from abroad than are sold here - is not itself a problem. It implies foreign borrowing. What matters is not the borrowing, but what has produced it and what it is being spent on. Current account imbalances are symptoms - but they can be symptoms of sensible decisions or of folly.
So, the current account deficit does not matter - does it?
Budget Deficit
Thus the government can create jobs.
But...
Government spending of debt money does not result in any net creation of jobs at all. It only confiscates wealth from private citizens and forces them to pay for centrally-planned jobs that the real economy usually neither needs nor benefits from.
Consider three people living in an island, running their own tiny economy. Bob, Sarah and Charlie are all farmers who grow their own food, making an honest living by working 8 hours a day to create the food, clothing and shelter they need to survive.
One day, Charlie decides he wants to be the Governor of the island. He tells Bob and Sarah that as Governor, he'll bring wealth and prosperity to them both. Initially, that sounds good, so Bob and Sarah agree to elect him Governor.
Then it turns out that the Governor is busy governing things on the island (i.e. deciding what everybody else should do), so he has no time to grow his own food. So he initiates a 50% tax on the productivity of Bob and Sarah, confiscating their food, clothing and resources in order to provide those items to himself without actually having to work for them. (This is a key function of government: To confiscate wealth from those who really work and redistribute it to those who pretend to work.)
Now, Bob and Sarah each have a choice: They can either work twice as much in order to pay their tax and still have enough to survive, or they can quit working altogether and hope to get aid from the government.
Sarah decides to work twice as much, so she starts working 16 hours a day, earning enough to pay the taxes to the Governor while still having some remaining food to feed herself and her family. Bob, on the other hand, decides he doesn't want to work 16 hours a day and would rather do nothing and apply to the Governor for "public assistance."
So now on this island of three people, where each of the three people used to work to feed themselves, only one person is working (Sarah), and the other two are living off the wealth that's being confiscated from her efforts.
One day Charlie, the Governor, says he has a solution! He says he will write a series of IOUs to Sarah in exchange for an extra portion of her food and other belongings. Using that currency borrowed from Sarah, he says he will "create a new job" for Bob and "end unemployment on the island."
Sarah reluctantly agrees and turns over the fruits of her labou to the Governor, who invents a job for Bob. "Bob," he says, "We need to build a bridge across this island!" And with the wave of his hand, he puts Bob to work creating a bridge (that nobody needs) while getting paid by wealth that has been confiscated from the only person on the island still working (Sarah).
So now we have ONE person actually doing productive work, a second person living off the confiscated wealth of that person (the Governor), and a third person working a useless job that's now paid for by the first person as well. This means we have ONE person supporting THREE. And while the island is at "full employment," two out of three people are actually doing jobs that don't materially contribute to the wealth and abundance of island's residents.
And the best part? Guess who gets to work even more to pay back the IOUs that the Governor traded with Sarah? Well Sarah, of course, because those IOUs are public debt paid back by taxpayers.
The problem on this little island is NOT that insufficient money is being spent on an economic stimulus program; the problem is that the island suffers from too many bureaucrats and too much debt spending.
The solution?
Fire the Governor and the government worker, shrink the size of government and get everybody back to working their own gardens, growing their own food and supporting their own families. Productivity on the island would triple, and people would have to get back to doing honest, productive work instead of living like parasites off the efforts of taxpayers.

If the price for inferior good rises the difference between inferior good and normal good will get less and because of that more people will switch to the normal good.
Yes but not everyone. I am referring to the people that do NOT switch!
In addition to that if the price of an inferior good rises it doesn't mean that the real income of all people becomes less. It will become less only for those who buy only that good.
I think the answer could be :
If the real income falls because of people spent more on inferior goods, therefore the inferior goods wont be demanded more because they bought inferior goods already.
But if the good is a consumer non-durable then there may be regular puchases
Rise in price of inferior goods will depend on how much demand response to the change in prise, it does not depend on the YED.
