Question: How did the political union that St. Barts joined in 2012 rank the economy of the nation where Wengen, and the birthplace of Fränzi Aufdenblatten are located?

full_context: Document 1: Switzerland: Switzerland has an overwhelmingly private sector economy and low tax rates by Western World standards; overall taxation is one of the smallest of developed countries. Switzerland is a relatively easy place to do business, currently ranking 20th of 189 countries in the Ease of Doing Business Index. The slow growth Switzerland experienced in the 1990s and the early 2000s has brought greater support for economic reforms and harmonization with the European Union. According to Credit Suisse, only about 37% of residents own their own homes, one of the lowest rates of home ownership in Europe. Housing and food price levels were 171% and 145% of the EU-25 index in 2007, compared to 113% and 104% in Germany.
Document 2: Saint Barthélemy: One senator represents the island in the French Senate. The first election was held on 21 September 2008 with the last election in September 2014. St. Barthélemy became an overseas territory of the European Union on 1 January 2012, but the island's inhabitants remain French citizens with EU status holding EU passports. France is responsible for the defence of the island and as such has stationed a security force on the island comprising six policemen and thirteen gendarmes (posted on two-year term).
Document 3: Franz Klammer: Franz Klammer (born 3 December 1953) is a former champion alpine ski racer from Austria. Klammer overwhelmingly dominated the downhill event for four consecutive World Cup seasons (1975-78). He was the gold medalist at the 1976 Winter Olympics in Innsbruck, winning the downhill at Patscherkofel by a margin of 0.33 seconds with a time of 1:45.73. He won 25 World Cup downhills, including four on the Hahnenkamm at Kitzbühel. He holds the record for the most victories (four) on the full course at Kitzbühel.
Document 4: Alps: The lower regions and larger towns of the Alps are well-served by motorways and main roads, but higher mountain passes and byroads, which are amongst the highest in Europe, can be treacherous even in summer due to steep slopes. Many passes are closed in winter. A multitude of airports around the Alps (and some within), as well as long-distance rail links from all neighbouring countries, afford large numbers of travellers easy access from abroad.
Document 5: Saint Barthélemy: Saint-Barthélemy (French: Saint-Barthélemy, French pronunciation: ​[sɛ̃baʁtelemi]), officially the Territorial collectivity of Saint-Barthélemy (French: Collectivité territoriale de Saint-Barthélemy), is an overseas collectivity of France. Often abbreviated to Saint-Barth in French, or St. Barts or St. Barths in English, the indigenous people called the island Ouanalao. St. Barthélemy lies about 35 kilometres (22 mi) southeast of St. Martin and north of St. Kitts. Puerto Rico is 240 kilometres (150 mi) to the west in the Greater Antilles.
Document 6: Saint Barthélemy: Saint Barthélemy was for many years a French commune forming part of Guadeloupe, which is an overseas region and department of France. Through a referendum in 2003, island residents sought separation from the administrative jurisdiction of Guadeloupe, and it was finally accomplished in 2007. The island of Saint Barthélemy became an Overseas Collectivity (COM). A governing territorial council was elected for its administration, which has provided the island with a certain degree of autonomy. The Hotel de Ville, which was the town hall, is now the Hotel de la Collectivité. A senator represents the island in Paris. St. Barthélemy has retained its free port status.
Document 7: Switzerland: Switzerland is one of the richest and wealthiest countries in the world. Switzerland ranks top or close to the top in several metrics of national performance, including government transparency, civil liberties, quality of life, economic competitiveness, and human development. It has the highest nominal wealth (financial and non-financial assets) per adult in the world according to Credit Suisse and the eighth-highest per capita gross domestic product on the IMF list. Zürich and Geneva have each been ranked among the top cities with the highest quality of life in the world, with the former ranked 2nd globally, according to Mercer.
Document 8: Economy of Switzerland: The economy of Switzerland is one of the world's most stable economies. The service sector has also come to play a significant economic role, particularly the Swiss banking industry and tourism. The economy of Switzerland ranks first in the world in the 2015 Global Innovation Index and the 2017 Global Competitiveness Report. According to United Nations data for 2016, Switzerland is the third richest landlocked country in the world after Liechtenstein and Luxembourg, and together with Norway the only two countries in the world with a GDP per capita above US $70,000 that are neither island nations nor ministates.
Document 9: Alps: In the first half of the 20th century the Olympic Winter Games were held three times in Alpine venues: the 1924 Winter Olympics in Chamonix, France; the 1928 Winter Olympics in St. Moritz, Switzerland; and the 1936 Winter Olympics in Garmisch-Partenkirchen, Germany. During World War II the winter games were canceled but after that time the Winter Games have been held in St. Moritz (1948), Cortina d'Ampezzo (1956), Innsbruck, Austria (1964 and 1976), Grenoble, France, (1968), Albertville, France, (1992), and Torino (2006). In 1930 the Lauberhorn Rennen (Lauberhorn Race), was run for the first time on the Lauberhorn above Wengen; the equally demanding Hahnenkamm was first run in the same year in Kitzbühl, Austria. Both races continue to be held each January on successive weekends. The Lauberhorn is the more strenuous downhill race at 4.5 km (2.8 mi) and poses danger to racers who reach 130 km/h (81 mph) within seconds of leaving the start gate.
Document 10: Alps: The region is serviced by 4,200 km (2,600 mi) of roads used by 6 million vehicles. Train travel is well established in the Alps, with, for instance 120 km (75 mi) of track for every 1,000 km2 (390 sq mi) in a country such as Switzerland. Most of Europe's highest railways are located there. Moreover, plans are underway to build a 57 km (35 mi)-long sub-alpine tunnel connecting the older Lötschberg and Gotthard tunnels built in the 19th century.
Document 11: Fränzi Aufdenblatten: Born in Zermatt, Valais, Aufdenblatten made her World Cup debut in March 2000 in a giant slalom at Sestriere. She scored four podium finishes on the World Cup: one win in a super-G in Val-d'Isère in December 2009, and three third places in downhill at Haus im Ennstal (2004), Bad Kleinkirchheim (2006), and Lenzerheide (2014). Aufdenblatten competed in three Winter Olympics (2002, 2006 and 2014) and her best finish was a sixth place in the 2014 super-G at Rosa Khutor.
Document 12: Otto Furrer: Furrer was born in Zermatt. He became a world champion in the combined event, received a silver medal in the slalom and a bronze medal in the downhill in Cortina d'Ampezzo in 1932. He was killed in an accident on the Matterhorn.
Document 13: Saint Barthélemy: On 7 February 2007, the French Parliament passed a bill granting COM status to both St. Barthélemy and (separately) to the neighbouring Saint Martin. The new status took effect on 15 July 2007, when the first territorial council was elected, according to the law. The island has a president (elected every five years), a unicameral Territorial Council of nineteen members who are elected by popular vote and serve for five-year terms, and an executive council of seven members. Elections to these councils were first held on 1 July 2007 with the last election in March 2012.
Document 14: Switzerland: The World Economic Forum's Global Competitiveness Report currently ranks Switzerland's economy as the most competitive in the world, while ranked by the European Union as Europe's most innovative country. For much of the 20th century, Switzerland was the wealthiest country in Europe by a considerable margin (by GDP – per capita). In 2007 the gross median household income in Switzerland was an estimated 137,094 USD at Purchasing power parity while the median income was 95,824 USD. Switzerland also has one of the world's largest account balances as a percentage of GDP.
Document 15: Alps: Some high mountain villages, such as Avoriaz (in France), Wengen, and Zermatt (in Switzerland) are accessible only by cable car or cog-rail trains, and are car free.
