At the first sign of excess profitability in the industry, competitors flock to the industry. As shown in Figure 1, an industry that is easy to enter but difficult to leave has intense industry rivalry and low profitability. If we combine entry and exit, we can predict industry rivalry, stability and profitability. High fixed costs - High levels of dedicated fixed costs tend to be an impediment to leaving an industry.Specialized skills - Highly specialized skills by industry participants that cannot be utilized in other industries tend to be an impediment to leaving the industry. ![]() Investment in specialist equipment - Investments in specialized equipment that cannot readily be used in other industries tends to be an impediment to leaving the industry.Government standards - Industries where rigid industry standards exist tend to have limited entry.Permitting requirements - Industries where permitting and licenses are required to establish production tend to have limited entry.Established brand identity - Industries dominated by branded products are difficult to enter due to the large amount of time and money required to create a competing branded product.High switching costs - The tendency for buyers of an industry’s products to be reticent about switching to a new supplier tends to limit entry.Intellectual property - Patents and other types of proprietary intellectual property are very effective in limiting industry entry.Capital intensive - A large capital investment per unit of output in facilities tends to limit industry entry.Economies of size - The need for a large volume of production and sales to reach the cost level per unit of production for profitability is a barrier to entry.Some of the common barriers to entry and exit are listed below. On the other end, industries that are difficult to exit have more rivalry than industries that are easy to leave. So, rivalry among competitors can be intense. Conversely, industries that are easy to enter attract new companies into the industry during periods of profitability. In general, industries that are difficult for new competitors to enter may enjoy periods of good profitability and limited rivalry among competitors. A barrier to exit is something that blocks or impedes the ability of a company (competitor) to leave an industry. The overwash habitat is home to cord grass and sawgrass.Teaching activity Barriers to Entry and ExitĪ barrier to entry is something that blocks or impedes the ability of a company (competitor) to enter an industry. The dune part of the island is also a hostile habitat due to its high salt content with the primary plants being bitter panicum and sea oats whose root systems help in stabilizing the dunes. The animals found include crabs and burrowing worms which feed on bacteria in the sand. The beach habitat of the barrier island is a harsh environment to sustain life due to its lack of fresh water and frequent submerging during high tides. The type of plant and animal species located on the barrier islands is dependent on their location on the island. The over-wash area of the island is also known as the barrier flat and is formed when sediments are pushed further inwards by hurricanes. Stability of the sand dune is caused by the growth of natural vegetation or grows artificially through the construction of fences. The dune is the part of the island formed by sand deposited and shaped by winds. The beach is the part of the island which borders the open ocean and consists of the sand which is deposited by the ocean waves. After hundreds of years, the sediments built up and formed barrier islands.Ī barrier island is comprised of a beach, sand dunes, over-wash, and salt marshes. The sea levels also began to rise, bringing with them sediments which were deposited on the exposed ridges along the beaches. The theory argues that 18,000 years ago, increased global temperatures caused glaciers to melt which also caused them to recede towards the poles. One theory links the formation of barrier islands to the end of the most recent Ice Age. There are several theories which have been fronted. Scientists have yet to come up with a solid explanation of how the barrier islands were formed, but it is accepted that the barrier islands are formed in micro-tidal coasts where tides do not exceed two meters. Barrier islands vary in size with some islands extending over 100 miles. While barrier islands are found all over the world, they are more prominent on the North American east coast and specifically around the Gulf of Mexico. ![]() A barrier island is a critically important feature on the coast as it acts as the coast’s first line of defence against storms and hurricanes and minimizes the impact and potentially lethal effects of the storms. A barrier island is a ridge made of sand, found parallel to the main coast with a lagoon or a bay separating the two.
