Introduction

Game theory is a branch of applied mathematics which for the first time was discussed a letter written by James Waldegrave in 1713. In this letter Waldegrave provides a minimax mixed  solution to a two-person version of the card game le Her. It was not until the publication of Antoine Augustin Cournot’s Researches into the Mathematical Principles of the Theory of Wealth in 1838 that a general game theoretic analysis was pursued. The game theory studies strategic situations where players choose different actions in an attempt to maximize their returns. First developed as a tool for understanding  behavior, game theory is now used in many diverse academic fields, ranging from  to .

Game is an abstraction of the particular economic situation and such information may have either descriptive or normative.

In our case we’ll use game theory to analyze an oligopoly competition of two great rivals, Wal-Mart and Carrefour, in the Chinese market. This research will focus on particular sets of strategies known as equilibria, which form an extensive form game in our case.

Brief history of Wal-Mart:

In 1962 Sam Walton founded a discount store in Arkansas, US, and it was the first WAL-MART store. The advantage of her store over its rivals lied in everyday low prices offered to the customers and a promise of satisfaction together with high quality goods supplied. In the early 70’s Wal-Mart extended its operation all around the USA and started opening stores abroad. There were branches set in Canada, Mexico, Brazil and Western Europe. The first Wal-Mart superstore was established in Montana in 1988. The super centre was a new type of stores which was created through combination of a grocery store with a discount store. Wal-Mart had succeeded in selling general merchandise and durables, but besides that its managers wanted to make profits in grocery for people shop for food twice as often as for the other goods. At the same time Wal-Mart was developing a new concept called the NEIGHBOURHOOD market. Such markets used to sell and store fruit and vegetables, pharmacy, offered a 24-hour photo shop service and a selection of classic Wal-Mart hard goods. The purpose of these Neighborhood markets was to keep on attracting surrounding neighbors who might be in a hurry or want only a few items.

Apart from Wal-Mart’s everyday low prices strategy, the company has also established highly automated distribution centers accompanied with a wide-ranging commercial support and implemented a computerized inventory system. This meshwork allowed the company to check every commodity in stock and on shelf within more than 4000 stores globally during one hour. All these measures lowered expenses and sped up the check out.

Nowadays the company operates 3600 Wal-Marts: Sam’s club membership - only warehouse stores, Wal-Mart super centers worldwide with major operations in Latin America, Canada, Europe and Asia. The executives of Wal-Mart expect South American market to build many more stores.

In 1997 Wal-Mart acquired 21 stores of Wertkauf chain in Germany and in 1999 ASDA in Britain, a company which served over 100 million customers worldwide weekly, was bought by Wal-Mart too (Economist 2002). Besides that, in 2000 Wal-Mart sales exceeded those of GM for the first time and Wal-Mart became the largest world enterprise.

Brief history of Carrefour

The first ‘hypermarket’ was opened in France in 1950. Just after the world war the consumer’s shopping desire was active and the hypermarket became a profitable business. It was Carrefour’s idea to initiate ‘hypermarket’ which would specialize in mass-sales: low delivery cost and everyday discounts to achieve high stock rotation and asset turnover. The success aspect includes low selling price, one-step shopping, fresh food, free parking and self-service. Carrefour presented a public offering in 1970 and introduced its own payment card (pass card) in 1989. In 1991 45 shops were opened in Western Europe. Since 1999 the Carrefour group has drawn its developments and acquisitions into various businesses to implement an innovative strategy – the multi-format approach.

The first step that Carrefour made out of France was to Belgium and from mid-70’s Carrefour started expansion out of the EU to such countries as Brazil and the USA. However, the strategy appeared to be a failure in the USA. The only two hypermarkets in America had to close down and Carrefour completely withdrew its stores from the US retailing market.

 

Although Carrefour had no success in the United States, it still had 7 030 stores and more than 340 thousand employees all around the world. The sales ran up to 80 billion that made Carrefour become the largest retailer in Europe and the second largest in the world.

Asia conflict

These two giant retailers were rarely faced with each other in direct competition. Wal-Mart prefers not to enter Carrefour force regions in Europe – Germany and the UK. In South America - both Carrefour and Wal-Mart didn’t compete vehemently. It seems to be a tacit avoid notwithstanding that both retailers have increased the speed of global expansion.

Since China actualized open-door policy, the purchasing power dramatically increased. Since 1980 both traditional supermarket and department store hasn’t been meeting the demands of one-step shopping. Therefore, huge amount of retailers with required conditions emerged as time required.
