Question: what is the economy of the capital of the state Russel Farnham was born?

full_context: Document 1: Mexico City: Mexico City is one of the most important economic hubs in Latin America. The city proper (Federal District) produces 15.8% of the country's gross domestic product. According to a study conducted by PwC, Mexico City had a GDP of $390 billion, ranking it as the eighth richest city in the world after the greater metropolitan areas of Tokyo, New York City, Los Angeles, Chicago, Paris, London and Osaka/Kobe (and the richest in the whole of Latin America). Excluding the rest of the Mexican economy, Mexico City alone would rank as the 30th largest economy in the world. Mexico City is the greatest contributor to the country's industrial GDP (15.8%) and also the greatest contributor to the country's GDP in the service sector (25.3%). Due to the limited non-urbanized space at the south—most of which is protected through environmental laws—the contribution of the Federal District in agriculture is the smallest of all federal entities in the country. Mexico City has one of the world's fastest-growing economies and its GDP is set to double by 2020.
Document 2: Russel Farnham: Russel Farnham was born in Massachusetts in 1784 and left home to join one of two expeditions organized by John Jacob Astor to establish the Pacific Fur Company at the mouth of the Columbia River. Farnham, hired as a clerk, was part of the "Tonquin" party under Captain Jonathan Thorn who were to travel by sea around Cape Horn arriving on the Pacific coast. However, the party soon met with disaster with the death of Thorn and the destruction of their ship soon after their arrival.
Document 3: Fort Clatsop: Fort Clatsop was the encampment of the Lewis and Clark Expedition in the Oregon Country near the mouth of the Columbia River during the winter of 1805 - 1806. Located along the Lewis and Clark River at the north end of the Clatsop Plains approximately 5 miles (8.0 km) southwest of Astoria, the fort was the last encampment of the Corps of Discovery, before embarking on their return trip east to St. Louis.
Document 4: New York City: New York is a global hub of international business and commerce. In 2012, New York City topped the first Global Economic Power Index, published by The Atlantic (to be differentiated from a namesake list published by the Martin Prosperity Institute), with cities ranked according to criteria reflecting their presence on similar lists as published by other entities. The city is a major center for banking and finance, retailing, world trade, transportation, tourism, real estate, new media as well as traditional media, advertising, legal services, accountancy, insurance, theater, fashion, and the arts in the United States; while Silicon Alley, metonymous for New York's broad-spectrum high technology sphere, continues to expand. The Port of New York and New Jersey is also a major economic engine, handling record cargo volume in the first half of 2014.
Document 5: Jonathan Russell: Born in Providence, Rhode Island on February 27, 1771, Russell graduated from Brown University (then Rhode Island College) in 1791. He studied law and was admitted to the bar, but did not practice. He engaged in mercantile pursuits for a number of years. In 1808 he was appointed Collector of the Port of Bristol.
Document 6: South Pass (Wyoming): In 1823 a St. Louis merchant named William Henry Ashley (started the rendezvous system) led a party up the Sweetwater to its source, rediscovered the pass (look back to previous paragraph), and spent the summer in its vicinity trapping. He returned again in 1824, this time going as far as Great Salt Lake and setting up a trading post there, which after three profitable years he sold to the Rocky Mountain Fur Company, headed by William Sublette, and David Jackson.
Document 7: Boston: In addition to city government, numerous commissions and state authorities—including the Massachusetts Department of Conservation and Recreation, the Boston Public Health Commission, the Massachusetts Water Resources Authority (MWRA), and the Massachusetts Port Authority (Massport)—play a role in the life of Bostonians. As the capital of Massachusetts, Boston plays a major role in state politics.
Document 8: Boston: Boston is an intellectual, technological, and political center but has lost some important regional institutions, including the acquisition of The Boston Globe by The New York Times, and the loss to mergers and acquisitions of local financial institutions such as FleetBoston Financial, which was acquired by Charlotte-based Bank of America in 2004. Boston-based department stores Jordan Marsh and Filene's have both been merged into the Cincinnati–based Macy's. Boston has experienced gentrification in the latter half of the 20th century, with housing prices increasing sharply since the 1990s. Living expenses have risen, and Boston has one of the highest costs of living in the United States, and was ranked the 129th most expensive major city in the world in a 2011 survey of 214 cities. Despite cost of living issues, Boston ranks high on livability ratings, ranking 36th worldwide in quality of living in 2011 in a survey of 221 major cities.
Document 9: Boston: A global city, Boston is placed among the top 30 most economically powerful cities in the world. Encompassing $363 billion, the Greater Boston metropolitan area has the sixth-largest economy in the country and 12th-largest in the world.
Document 10: Boston: Boston is sometimes called a "city of neighborhoods" because of the profusion of diverse subsections; the city government's Office of Neighborhood Services has officially designated 23 neighborhoods.
Document 11: Boston: With nearly a third of Bostonians using public transit for their commute to work, Boston has the fifth-highest rate of public transit usage in the country. Boston's subway system, the Massachusetts Bay Transportation Authority (MBTA—known as the "T") operates the oldest underground rapid transit system in the Americas, and is the fourth-busiest rapid transit system in the country, with 65.5 miles (105 km) of track on four lines. The MBTA also operates busy bus and commuter rail networks, and water shuttles.
Document 12: New Delhi: The 2011 World Wealth Report ranks economic activity in New Delhi at 39, but overall the capital is ranked at 37, above cities like Jakarta and Johannesburg. New Delhi with Beijing shares the top position as the most targeted emerging markets retail destination among Asia-Pacific markets.
Document 13: Boston: Tourism also composes a large part of Boston's economy, with 21.2 million domestic and international visitors spending $8.3 billion in 2011; excluding visitors from Canada and Mexico, over 1.4 million international tourists visited Boston in 2014, with those from China and the United Kingdom leading the list. Boston's status as a state capital as well as the regional home of federal agencies has rendered law and government to be another major component of the city's economy. The city is a major seaport along the United States' East Coast and the oldest continuously operated industrial and fishing port in the Western Hemisphere.
Document 14: Boston: Federally, Boston is split between two congressional districts. The northern three-fourths of the city is in the 7th district, represented by Mike Capuano since 1998. The southern fourth is in the 8th district, represented by Stephen Lynch. Both are Democrats; a Republican has not represented a significant portion of Boston in over a century. The state's senior member of the United States Senate is Democrat Elizabeth Warren, first elected in 2012. The state's junior member of the United States Senate is Democrat Ed Markey, who was elected in 2013 to succeed John Kerry after Kerry's appointment and confirmation as the United States Secretary of State.
Document 15: Fort William (Oregon): Fort William was a fur trading outpost built in 1834 by the American Nathaniel Jarvis Wyeth, a Boston merchant, backed by American investors. It was located on the Columbia River on Wappatoo Island near the future Portland, Oregon. After a few years, in 1837 Wyeth sold the post to the British Hudson’s Bay Company, which had much more power in the region from its base at Fort Vancouver on the north side of the Columbia River near Fort William.
