The Cowles Foundation for Research in Economics is an economic research institute at Yale University. It was created as the Cowles Commission for Research in Economics at Colorado Springs in 1932 by businessman and economist Alfred Cowles. In 1939, the Cowles Commission moved to the University of Chicago under Theodore O. Yntema. Jacob Marschak directed it from 1943 until 1948, when Tjalling C. Koopmans assumed leadership. Increasing opposition to the Cowles Commission from the department of economics of the University of Chicago during the 1950s impelled Koopmans to persuade the Cowles family to move the commission to Yale University in 1955 where it became the Cowles Foundation.As its motto Theory and Measurement implies, the Cowles Commission focuses on linking economic theory to mathematics and statistics. Its advances in economics involved the creation and integration of general equilibrium theory and econometrics. The thrust of the Cowles approach was a specific, probabilistic framework in estimating simultaneous equations to model an economy. Its ultimate goal in doing so was to gain policy insight. The Cowles approach structured its models from a priori economic theory. One of its main contributions was in exposing the bias of ordinary least squares regression in identifying coefficient estimates. Consequently, Cowles researchers developed new methods such as the indirect least squares, instrumental variable methods, the full information maximum likelihood method, and the limited information maximum likelihood method. All of these methods used theoretical, a priori restrictions. According to an article by Carl F. Christ, the Cowles approach was grounded on certain assumptions: 1. simultaneous economic behavior; 2. linear or logarithmic equations and disturbances; 3. systematic, observable variables without error; 4. discrete variable changes as opposed to continuous; 5. a priori determination of exogeneity and endogeneity; 6. the existence of a reduced form; 7. independence of the explanatory variables; 8. a priori identified structural equations; 9. normally distributed disturbances with zero means, finite and constant covariances, a nonsingular covariance matrix, and serial independence; 10. a dynamically stable system of equations.Several Cowles associates have won a Nobel Memorial Prize in Economic Sciences for research done while at the Cowles Commission. These include Tjalling Koopmans, Kenneth Arrow, Gérard Debreu, James Tobin, Franco Modigliani, Herbert A. Simon, Joseph E. Stiglitz, Lawrence Klein, Trygve Haavelmo, Leonid Hurwicz and Harry Markowitz. The Cowles Foundation is located at 30 Hillhouse Avenue, New Haven, Connecticut.

The Whitney and Betty MacMillan Center for International and Area Studies at Yale, commonly known as the MacMillan Center, is a research and educational center for international affairs and area studies at Yale University. It is named after Whitney MacMillan and his wife Betty.

The Yale Collection of Musical Instruments, a division of the Yale School of Music, is a museum in New Haven, Connecticut. It was established in 1900 by a gift of historic keyboard instruments from Morris Steinert, and later enriched in 1960 and 1962 by the acquisition of the Belle Skinner and Emil Herrmann collections. Initially housed under the dome of Woolsey Hall, it was moved in 1961 to a historic Romanesque structure on Hillhouse Avenue, constructed in 1895 for the Alpha Delta Phi fraternity.

Rudolph Hall (built as the Yale Art and Architecture Building, nicknamed the A & A Building, and given its present name in 2007) is one of the earliest and best-known examples of Brutalist architecture in the United States. Completed in 1963 in New Haven, Connecticut, the building houses Yale University's School of Architecture. Until 2000, it also housed the School of Art.

The Russell Henry Chittenden House is a historic house at 83 Trumbull Street in New Haven, Connecticut. Built in the 1880s, it was the longtime home of Russell Henry Chittenden, who lived there from 1887 to his death in 1943. Chittenden, known as the "father of American biochemistry", was a professor at Yale University, and the house was declared a National Historic Landmark in 1975 in recognition of his importance.

Hillhouse Avenue is a street in New Haven, Connecticut, famous for its many nineteenth century mansions, including the president's house at Yale University. Both Charles Dickens and Mark Twain have described it as "the most beautiful street in America." Much of the avenue is included in the Hillhouse Avenue Historic District, which extends to include houses on adjacent streets.

The Yale Jackson School of Global Affairs (formerly the Yale University Jackson Institute for Global Affairs) is a professional school of Yale University that specializes in global affairs. Based in New Haven, Connecticut, the school's mission is to "inspire and prepare Yale students for global leadership and service." It was established in 2010 and offers degrees for both undergraduate and graduate levels and includes the following programs: the Kerry Initiative, the Global Health Studies Program, the Yale World Fellows, and the Leitner Program on Effective Democratic Governance. It also hosts the Johnson Center for the Study of American Diplomacy. As of 2022, the school is led by dean James A. Levinsohn, Charles W. Goodyear Professor in Global Affairs. The Jackson Institute transitioned to a professional school in 2022. It is the first new Yale professional school created since 1976.

St. Mary Church is a Roman Catholic church in New Haven, Connecticut, part of the Archdiocese of Hartford. It is the seat of the city-wide Blessed Michael McGivney Parish. As of July 1, 2023, the consolidated city-wide parish operates eight churches for regularly scheduled worship. The parish now known as Blessed Michael McGivney Parish was the first Catholic parish erected in New Haven, and is the second oldest Roman Catholic parish in Connecticut. The parish was originally established in 1832 as Christ Church Parish, becoming Saint Mary Parish in 1848. The current Saint Mary church building, located on Hillhouse Avenue near Yale University, was dedicated in 1874. In 1882, Michael J. McGivney, the Saint Mary's assistant pastor, founded the Knights of Columbus at the parish. McGivney, whose remains are interred within the church, was beatified by Pope Francis in 2020. For 135 years, from 1886 until their departure in December 2021, St. Mary's parish had been run by friars of the Dominican Order. In 2021, priests from the archdiocese were assigned to Saint Mary Parish as part of second major restructuring of parishes in New Haven. On July 1, 2023, all parishes within the city of New Haven were formally merged into Saint Mary Parish to form Blessed Michael McGivney Parish. In 2018, the parish of St. Mary had previously merged with nearby St. Joseph Parish as part of an earlier diocesan-wide restructuring. The churches constituting the city-wide parish include: Saints Aeden and Brendan Church, Saint Anthony Church, Saint Francis Church, Saint Joseph Church, Saint Mary Church, Saint Michael Church (Italian), Saint Thomas Moore Chapel at Yale, Saint Martin de Porres Church, and Saint Stanislaus Church (Polish). Saint Bernadette Church, though within the city of New Haven, is part of St. Pio of Pietrelcina Parish of East Haven, Connecticut. A separate Eastern Catholic parish of Saint Michael, part of the Ukrainian Eparchy of Stamford, also exists within New Haven.

Benjamin Franklin College is a residential college for undergraduates of Yale College in New Haven, Connecticut. It opened to students for the 2017 academic year.

Berzelius is a secret society at Yale University named for the Swedish scientist Jöns Jakob Berzelius, considered one of the founding fathers of modern chemistry. Founded in 1848, 'BZ', as the society is called often, is the third oldest society at Yale and the oldest of those of the now-defunct Sheffield Scientific School, the institution which from 1854 to 1956 was the sciences and engineering college of Yale University. Berzelius became a senior society in the tradition of Skull and Bones, Scroll and Key, and Wolf's Head in 1933 when the Sheffield Scientific School was integrated into Yale University. Book and Snake and St. Elmo, also societies from Sheffield, followed suit. Skull and Bones, founded in 1832, Scroll and Key, founded in 1841, and Wolf's Head, founded in 1883, catered to students in the Academic Department, or liberal arts college.The alumni trust organization, the 1848 Association, owns the society's building. Outsiders refer to the building as a 'tomb', the customary appellation for a secret society structure at Yale; however, many BZ members refer to their building as "The Hall." This is likely a transferred linguistic remnant of the tradition of the 'Sheff' secret societies, which had 'halls' for residential use and 'tombs' as separate meeting places, in contrast to the Yale College senior secret societies, which maintained only "tombs."

Yale College is the undergraduate college of Yale University. Founded in 1701, it is the original school of the university. Although other Yale schools were founded as early as 1810, all of Yale was officially known as Yale College until 1887, when its schools were confederated and the institution was renamed Yale University. It is ranked as one of the top colleges in the United States.Originally established to train Congregationalist ministers, the college began teaching humanities and natural sciences by the late 18th century. At the same time, students began organizing extracurricular organizations: first literary societies, and later publications, sports teams, and singing groups. By the middle of the 19th century, it was the largest college in the United States. In 1847, it was joined by another undergraduate school at Yale, the Sheffield Scientific School, which was absorbed into the college in 1956. These merged curricula became the basis of the modern-day liberal arts curriculum, which requires students to take courses in a broad range of subjects, including foreign language, composition, sciences, and quantitative reasoning, in addition to electing a departmental major in their sophomore year. The most distinctive feature of undergraduate life is the school's system of residential colleges, established in 1932, and modeled after the constituent colleges of English universities. Undergraduates live in these colleges after their freshman year, when most live on the school's Old Campus.
