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.

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."

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 James Dwight Dana House, also known as the Dana House, is a historic 19th-century Italianate house at 24 Hillhouse Avenue in New Haven, Connecticut, in the United States. This building, designed by New Haven architect Henry Austin, was the home of Yale University geology professor James Dwight Dana (1813–95). It was declared a National Historic Landmark in 1965 for its association with Dana, who produced the first published works emphasizing that the study of geology was a much broader discipline than the examination of individual rocks.

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.

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.

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 William H. Taft Mansion is a historical site located at 111 Whitney Avenue in New Haven, Connecticut, United States. It was built in 1870. It is known as the Taft Mansion because U.S. President William Howard Taft owned it for a period around the time of World War I, although he may never have lived in it. In 1920 it was famously burgled by Carl Panzram, in revenge for Taft sentencing him to three years in prison at Fort Leavenworth. After selling what he had stolen, he went on a further crime spree which often included shooting his victims with a gun he stole from the house. Taft owned the house until 1921.In 2014, the William F. Buckley Jr. Program at Yale University relocated to the mansion with an option to purchase it. The location across the street from the Peabody Museum is particularly apt for the group, as Taft was both a Republican and a Yale graduate.

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.

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.
