why is barrier to entry important?

A barrier to entry is an important consideration when creating any business plan.  You must consider how you will enter into a market and if it is feasible.  If the barriers to entry are too high, then you are entering a monopolistic or oligopolistic market.  If barriers to entry are too low, then you are entering into a saturated market or a market which will become saturated.  \n\nFurthermore, if barriers to entry are low you need a larger degree of differentiation to retain a competetive advantage.  Barriers to entry can determine how much resources you will need to allocate to marketing to remain competetive.\n\nBarriers to entry are not only governmental regulations, they can be competitition, high amount of capital needed to enter into market, etc.  Market saturation I feel is an effect of low barriers to entry, but others will tell you that it is a barrier to entry (both perspectives are true).

If we don't have strict or a National Security policy in which we protect our borders ....then that leaves us vulnerable to any person immigrating into our Country with the wrong intentions or reasons for they are coming into our Country. The easier it is to get into our Country ....via our borders to the north and the south ....then the easier it is to commit terrorist acts in or on the USA.

From my experience, it is for a couple of reasons.  First, the holiday season can be crazy for stores, and it helps the store control crowds better if everyone enters through one door and exits through one door.  Also, it is a loss prevention issue.  Shoplifters want to make a quick exit, and employees can keep track of people leaving the store better if they are only exiting through one door.

The correct term and description is ILLEGAL Immigrant. The option to enter any country is always opened and available.But for some reasons best known to these people, they always seek for illegal ways to enter the country they desire. If u refer to them as UNDOCUMENTED IMMIGRANTs, u make it look as if the government is relunctant, or inefficient at documenting immigrants.The Posts are there for them to be checked and documented but they always avoid the legal means. That makes both the act, and the actor ILLEGAL. For example, a visitor has the privilege to knock at your door and seek for entry, and you can allow him if he has  genuine reasons, but if he choses to come in through the window, then he is a burglar, and NEVER an undocumented visitor.

Ignor it and go about your business. It is important for citizens to do that in order to show the ILLEGAL's the door.

I get the impression that most people are not even aware that it is there.  As for getting your answer in first, there is no reason not to go back and modify your answer.  It will still be first.

More important than the key codes is the record of who gets them and when.  This is done to prevent possible criminal activity.

If you mean the new one it is to get cheap labor for big business, if it passes.  However, no one knows what it will be like yet, until when and if it survives in the Bill when it goes to the House. \n\nThe idea is that if the border is sealed, we will need more legal immigration.  This will be better because we can screen the people who come.  However, many think that letting more come before the border is secure is the wrong way to go. (I'm one of them.)  We need to see what comes out of the House.

It has made reliable freight transportation more important.  \n\nIf a country cannot safely and effectively move its goods to a country that is buying, the buying country is going to find another supplier.  \n\nThe way it used to be, if you found a source for a product you were stuck with them until you found another source.  Now, with the world economy opening goods are becoming easier to find.  Because of that exporting countries have to make sure that the transactions are a smooth as possible.  The first step is to make sure they have good, reliable transportation.

Visa is important because it allows a country to regulate the entry of aliens by allowing only those with legitimate purposes.

Single layer films are generally quite permeable to most gases.Barrier films are usually multi-layer films that have been designed to be impervious to gas migration. Some common examples of barrier films will be found in any grocery store. Bags used for packaging potato chips and meat products are gas barrier bags, garbage, freezer, and sandwich bags are not. To understand the difference in practical terms, compare the longevity of a helium-filled balloon made of rubber to a balloon made of foil barrier- the rubber balloon will shrink within hours, but the barrier film balloon will continue to wish you a "happy birthday", or "get well soon" in mid-air for weeks. \n\nConstruction\n\nAlmost all gas barrier films are made of multiple layers. The outer/top layer will be a strong (usually transparent) plastic with a relatively high melting point, often made of polyester (Mylar) or polypropylene. The inner/middle layer will be the gas barrier material (see next). The inside/bottom layer is almost always low density polyethylene, which softens at relatively low temperatures. Additional inner layers are sometimes used to increase the barrier properties of the film, and adhesives may be used to cement the layers. Note that polyester, polypropylene, and polyethyelene are all poor barrier layers on their own.

EU countries have to let u in, because that's the law so we're told as justification for the UK's immigration recently. The Commonwealth is different, you need to get enough points, IE you need to be of worth to the country you want to go to. I'm not sure about the rest, but i bet it isn't that difficult to get into an African country.
