Document Summary

Incomplete and symmetric information: all market participants don"t know some information. Example: the market for insurance contracts that cover the risk of an earthquake in california. Incomplete and asymmetric information: some market participants don"t know some information. Economics of information: asymmetric information leads to market failures: e. g. credit markets, insurance markets, labor markets; Was integrated with game theory in the 1980s. Answer: there is asymmetric information in the market for 1 year old cars, but not in the market for new cars. After 1 year, owners have more information about the car than buyers. Owners with negative information are more likely to sell than owners with positive information. 1 year old cars that are sold are more frequently bad than new cars. Lemons = used cars that are not good. At every price p buyers anticipate which qualities of cars will be offered. Buyers then compare their expected willingness to pay for the cars to the price.

Q:This week, we are discussing market types. In this forum, please pick one of the market types that are presented in your textbook and provide your own definition (use your own words) and example. What do you think are the benefits vs. deficiencies of your chosen market type?

Answer 1)

Perfect Competition

This kind of market type stipulates the overall advantage that a market has. In this market, there are many sellers and buyers.These players do not control the price of commodities or services but the prices are controlled by the demand and supply of goods and services. As a result of this, no one can determine the market price of commodities because customers will switch to the next best alternative. All the market players in this sense are price takers and the customers that subscribe to these goods have a lot of experience about the goods offered. It means therefore that they have adequate information about the goods available, which means, therefore, they are aware of the prices that are being charged. All the firms that exist in this kind of market type have a relatively small market share because of the existence of so many of them. The market is also characterized by free entry and exit of firms. New firms can enter the market if they so wish and create competition to the existing firms. Due to this nature of many firms, most of them only earn enough to keep them on the market and nothing more for these firms (Makowski & Ostroy, 2001).

Answer 2)

The Oligopoly; best recognized by few sellers, identical (or similar) products, and its difficult entryinto the market. A good way to determine if a market has an oligopoly is if the change in one seller, causes its "competition" to change likewise. Automotive, cell phone industries, and aviation are some examples of markets that have an oligopoly. In the automotive industry, if one vehicle producer (lets say Chevrolet) changes the body style of its line up, other "completion" is soon to follow. Notice how cars these days are getting nicer and nicer for the base model? Research and Development is greatly valued in an industry that has an oligopoly. This is because if a seller lowers prices, they understand that its competitors will soon follow with ease. But, if they develop a better improvement over its last model in technology, it is much harder to follow than just a reduction in price.

The advantage of an oiligolpoly is that the leaders can set prices instead of take them. Which leads to those that are in charge having the ability to increase profit margins above what they would be in a truly free market.

The disadvantage is that for those looking to try to get into the market will have much difficulty because of the common huge capitol expenditures required to actually compete with the big boys.

Mexico's automobile industry is booming. Bolstered by $19 billion in new investment from foreign carmakers, including Nissan, Honda, Volkswagen, and Mazda, vehicle production doubled between 2009 and 2014 to an estimated 3.2 million vehicles. This investment surge has transformed Mexico into the eighth-largest automaker in the world, and it's not over yet. In 2014 and 2015, Toyota, Mercedes-Benz, Hyundai-Kia, BMW, and Volkswagen all outlined plans to build new state-of-the-art factories in Mexico. Audi is also constructing a $1.3 billion factory that is slated for producing luxury sport-utility vehicles. The Audi factory is scheduled to open in 2016. Taken together, these new factories represent another $20 billion in investment that will push Mexico past Brazil and South Korea to become the sixth-largest car producer in the world by 2020 with an annual output of 4.7 million vehicles (for comparison, the U.S. industry makes some 11.5 million autos a year). The initial stimulus for the dramatic growth of the Mexican auto industry was the establishment of the North American Free Trade Agreement (NAFTA) in 1994. Prior to NAFTA, Mexico's auto industry was small and protected from foreign competition by high tariff barriers. Car prices in Mexico were two to three times higher than in the United States. Not only were cars in Mexico more expensive, exporting or importing cars and parts was also very tough. Shipments got delayed at the border and were difficult to move around because of poor infrastructure, which is a major problem in an industry in which tight logistics is critical. NAFTA removed most tariff and nontariff barriers to trade between Mexico, the United States, and Canada. This initially led to a flood of low-priced auto imports into Mexico from the United States, but it also gave auto manufacturers based in Mexico duty-free access to the large U.S. market next door. With labor costs in Mexico just a fraction of those in the United States, auto manufacturers now had to consider Mexico when planning new plants to serve the North American market. Mexico's shift to free trade didn't stop with NAFTA. Mexico spent much of the 2000s hammering out free trade deals with over 40 other countries, including the 28 states of the European Union, Japan, and Brazil. These deals give auto factories based in Mexico duty-free access to markets that contain 60 percent of the world's economic output, and they have helped transform Mexico into the fourth-largest auto exporter in the world. Eighty percent of the cars now produced in Mexico are exported to other countries, two-thirds of them to the United States. This unprecedented network of regional trade agreements has given Mexico an important edge when it comes to attracting new investment. For example, when BMW ships cars to Europe from its 20-year-old plant in South Carolina, it is hit with a 10 percent import duty. For a $50,000 car, that amounts to $5,000, which is a much bigger factor than differences in labor costs. A factory in Mexico can supply both the U.S. and the EU markets with duty-free automobiles. This was a major factor behind BMWs 2014 decision to build a new factory in central Mexico rather than the United States, far outweighing the $500 a car labor cost advantage that Mexico currently enjoys over the United States. The new BMW factory will supply the U.S. and EU markets, as well as Latin America. Indeed, because of differences in trade barriers, a car exported from the United States to Brazil costs 55 percent more than one exported from Mexico. As Mexico's auto industry has grown, auto-part suppliers have also followed manufacturers to Mexico. The large auto parts supplier Delphi, for example, has 30 factories in Mexico and generates revenues of $3 billion in the country. Employment at Delphi's facilities doubled to 24,000 between 2007 and 2014. Infrastructure has also improved dramatically, and customs clearance at the border is now quick and efficient. All of this bodes well for the future of the Mexican auto industry. However, not everyone is happy with what has happened. Some argue that growth in Mexico has come at the expense of factories in the United States, which has had a negative impact on employment growth in the U.S. auto industry. When BMW decided to build a factory in central Mexico, for example, it meant that it would not be expanding its South Carolina plant. The South Carolina plant will continue to operate, and no plants have been closed as a result of the growth of production in Mexico, but it is true that new plants are increasingly being located south of the border.

CASE DISCUSSION QUESTIONS

1. What was the initial impact of NAFTA on the U.S. and Mexican automobile markets? Who benefited most from this?

2. How did the impact of NAFTA start to change location decisions by automobile manufacturers over the years? How did this start to impact automobile production in Mexico and the United States?

3. Mexico has been very proactive in signing regional free trade deals in addition to NAFTA. How has this strategy impacted automobile consumers and producers in Mexico? How has it impacted automobile consumers and producers in the United States?

4. What lessons can United States policymakers draw from the growing success of the Mexican automobile industry that can be applied to future free trade deals, such as the deal currently being negotiated between the United States and the European Union?
