There is no question that the Irish economy changed when the euro was introduced. But whether converting to the euro was what caused those changes is a matter of speculation. Because Ireland is an island, and because it is located rather far away from other EU countries, some economists thought that the introduction of the euro would cause an increase in exports. The reasoning was that countries on the continent were used to trading with one another before the advent of the euro, and that Ireland would gain attention by being the new trading partner on the block.

This isn’t to say that the continent didn’t trade with Ireland before the euro, just that it became significantly easier with a common currency.

However, that’s not how it went down.

Ireland’s property price bubble began shortly before the introduction of the euro. After 2003, capital inflows rose more than 50% of the GDP – a phenomenal rate. Much of this capital was absorbed by locally controlled Irish banks.

The collapse in construction and real estate and the fall of property prices, along with the troubles of the banking system worldwide harmed employment and weakened the economy as the world headed into recession in 2008. But studies of other small economies in the periphery of Europe have found that the euro was neither necessary nor sufficient for the economic trouble in Ireland. In other words, the euro was along for the ride, but it wasn’t the euro’s fault that the economy rose rapidly then fell.

What the euro did was trigger low interest rates that got the property bubble underway, and eased the financing of the property bubble. This weakened some of the traditional restraints on emerging imbalances: it was uncharted territory for the Irish economy. The other economies in Europe and its surrounding regions that also suffered major economic setbacks, specifically Iceland and Latvia, were not members of the EU. So the introduction of the euro is not likely to be to blame for the economic downturn.

Another example, the fortunes of Portugal, another small country on the periphery of Europe and an EU member, show that a massive price bubble was not inevitable with the adoption of the euro.

There is no denying that after the introduction of the euro in 2002 there was a wave of optimism in EU countries based on the new currency system. But though the euro can be blamed as a cause of low interest rates that fueled the property boom, the currency itself does not appear to have changed the Irish economy any more than it would have changed had it not adopted the euro.

It’s hard to know what to do with old financial statements – which ones to keep and which to shred. But there are guidelines, and in general, if the statement could have to do with taxes, you should keep it for a long time, perhaps several years. Of course, if you do all your banking online, it is rather a moot point, because there aren’t paper records to protect. But how do you know what to do with other financial statements?

Tax returns should have the longest shelf life, as should cheques and receipts for things like charity contributions, mortgage interest, and other documents that may affect your taxes. You should keep such records for several years, if not permanently.

Documents related to pensions should be kept for at least a year, and permanently if possible. The same goes for bank statements where there might be something that relates to your taxes. For bank statements that don’t have any long term importance, you can get rid of them after a year.

You should keep your credit card statements anywhere from a couple of months to several years. Again, it depends on whether the statements contain tax related expenses. If not, keep your receipts until you get your monthly credit card statement. If they match up, go ahead and shred the receipts. Hang onto the credit card statement for another month or so, and if there are no purchases with long term importance or related to taxes, you can get rid of them then.

The term “get rid of” goes well beyond tossing your statements into the bin. At the very least, they should be run through a shredder. Cross cut shredders are more destructive than regular shredders, but even with regular shredders, if you mix up the shredded paper that collects, you’re going to put off all but the most determined (or crazy) criminals wanting your financial information.

Some people go farther than shredding their financial records. Some incinerate them, and others get very creative, using them to line the cat box or composting the bits with chicken manure (if they have chickens). These measures are probably not necessary, but it does point up the need to keep your financial information close to the chest.

If you have the option of having your statements online, it may be worthwhile. For one thing, they’ll be archived, and for another, you won’t accidentally leave them lying around in plain view where a dishonest repairman or dodgy roommate might see them.

Ireland is the only country that has a credit card stamp duty. A stamp duty is a tax the government imposes on certain legal documents. The word “stamp” is a holdover from the days when an actual physical stamp was attached to a document to prove that the duty had been paid. The stamp duty on Irish credit cards and charge cards is for €30 per year per account. Charge cards are like credit cards except there is no interest because you pay it off at the end of the month.

It is important to note that multiple cards attached to one account, such as an account where both spouses have a copy of the credit card, only one stamp duty is imposed. If you transfer a credit card account from one issuer to another, you can avoid paying the stamp duty again as long as you close the old account and have documentation from the account you’re closing saying so.

In 2007, Ireland had more than 2.3 million credit cards in circulation, more than double what it was in 1997. Even if only a quarter of those were attached to unique accounts, it would add up to over €20 million in credit card stamp duty income per year.

There is also a stamp duty levied on debit laser cards and ATM cards. For these cards, the tax is €10 on every ATM card or debit laser card, or €20 annually on every combined Laser/ATM card.However, with debit laser cards and ATM cards the duty is affixed on every card rather than every account.

While you may balk at having to prove that you’ve already paid the credit card stamp duty once in a year if you’ve switched cards, or if you think that it’s too much trouble to bother with, consider what would happen if 100,000 Irish citizens didn’t bother. The Irish government would get an extra €30 million in a year for no good reason.

Same thing with the duties on ATM and debit laser cards. If nobody bothered disputing the stamp duty if they switched cards after having paid the tax for the year, the government would rake in an extra €10 million. There’s no sense in trying to get out of paying the stamp duty, but at the same time there’s no reason for you to pay it twice in a year if you don’t have to.

Depending how you interpret the word “design,” you can pick a “best” in many ways. If you’re looking for a credit card that looks nice, then there are credit card issuers like Capital One whose platinum MasterCards can be personalized in many different ways. However, if you get a credit card with the lowest interest rate that does not have a “smart chip” as some European Visa cards do, you can personalize your card in an almost infinite number of ways with credit card skins.

Think of credit card skins like the “skins” that people choose to dress up their iPod. It’s like a wardrobe of tiny clothing that won’t keep your card from working like it’s supposed to (unless you have a “smart chip” Visa). Credit card skins are basically super thin stickers that you apply to the front of your card with a hole over where your name, card number, and expiration date go.

There are websites where you can choose from a dizzying array of credit card skins with every kind of graphic or message you can imagine, from gay pride to preppy Argyle designs. Creditcovers.com has hundreds of designs to choose from and an opportunity to make your own design and make royalties from it if it sells.

Businesses can order custom credit card skins as unique and fun promotional giveaways. You can also make your own graphic credit card skins using a template in Adobe PhotoShop or a similar graphics program using t-shirt transfer paper and a color inkjet printer. Once you have the design the right size and the right shape (with the hole for your name, card number, and expiration date, print it out onto t-shirt transfer paper then cut the design out with scissors. You then put spray mount on the card, peel the backing from the transfer paper and place the design on the card. Put the ironing paper that comes with the t-shirt transfer paper over the card on an ironing board or reasonable facsimile. Preheat iron to “low.” Iron the card for 15 seconds. Check if the design adheres. If not, iron for 15 more seconds. But be careful, lest you melt your credit card with too much heat. Let cool. After the card has cooled cut away excess transfer paper with a mat knife.

Sometimes the best design for a credit card is the one that brings you the lowest interest rate. Once you have that, if it isn’t beautiful enough for you, then skins are the way to personalize your card into a statement about yourself.
