In economics, a good is something that is intended to satisfy some wants or needs of a consumer and thus has economic utility. It is normally used in the plural form—goods—to denote tangible commodities such as products and materials.

Although in economic theory all goods are considered tangible, in reality certain classes of goods, such as information, may only exist in intangible forms. For example, among other goods an apple is a tangible object, while news belongs to an intangible class of goods and can be perceived only by means of an instrument such as print, broadcast, or computer.

Goods are contrasted with services, which are intangible commodities.

Goods may increase or decrease their utility directly or indirectly and may be described as having marginal utility. Some things are useful, but not scarce enough to have monetary value, such as the Earth's atmosphere, these are referred to as 'free goods'.

In economics, a bad is the opposite of a good. Ultimately, whether an object is a good or a bad depends on each individual consumer and therefore, it is important to realize that not all goods are good all the time and not all goods are goods to all people.

Aamir Hussain Khan (pronounced [ˈaːmɪr ˈxaːn]) (born 14 March 1965) is an Indian film actor, director and producer who has established himself as one of the leading actors of Hindi cinema.

Starting his career as a child actor in his uncle Nasir Hussain's film Yaadon Ki Baaraat (1973), Khan began his professional career eleven years later with Holi (1984) and had his first commercial success with Qayamat Se Qayamat Tak (1988). He received his first National Film Award as a Special Jury Award for his roles in the films Qayamat Se Qayamat Tak (1988) and Raakh (1989). After eight previous nominations during the 1980s and 1990s, Khan received his first Filmfare Award for Best Actor for his performance in the major grosser Raja Hindustani (1996) and later earned his second Best Actor award for his performance in the Academy Award-nominated Lagaan, which also marked the debut of his own production company.

Following a four-year break from acting, Khan made his comeback playing the title role in the historical Mangal Pandey: The Rising (2005), and later won a Filmfare Critics Award for Best Actor for his role in Rang De Basanti (2006). The following year, he made his directorial debut with Taare Zameen Par, for which he received a Filmfare Award for Best Director. This was followed by Ghajini (2008), which became the highest grossing film of that year, and 3 Idiots (2009), which became the highest-grossing Bollywood film of all-time, unadjusted for inflation. The Government of India honoured him with the Padma Shri in 2003 and the Padma Bhushan in 2010 for his contributions towards the arts.

Katrina Kaif (born 16 July 1984) is a British Indian actress and former model who appears in Indian films, mainly in the Hindi-language film industry. She has also appeared in Telugu and Malayalam films. She was voted the sexiest Asian woman in the world by Eastern Eye in the years 2008, 2009 and 2010. Being a British citizen, she works in India on an employment visa.

Kaif made her acting debut with Kaizad Gustad's box office bomb Boom (2003). She tasted success in 2007 with Vipul Shah's Namastey London and followed with such films as Anees Bazmee's Welcome (2007), Abbas-Mustan's Race (2008) and Kabir Khan's New York (2009). She has since appeared in critically and commercially successful films like Prakash Jha's political thriller Rajneeti (2010) and Zoya Akhtar's dramedy Zindagi Na Milegi Dobara (2011).

Kaif was born in Hong Kong, to an Indian Kashmiri father, Mohammed Kaif, and an English mother, Susanna Turquotte, both of whom are British citizens. Her parents divorced when she was very young. Kaif once stated, "My dad, unfortunately, and not out of choice, has had no influence on our upbringing, on our religious or social or moral bearings." When she came to India, she changed her surname to Kaif, because it was Indian in origin. Furthermore, Ayesha Shroff has maintained that the actress' original name is Katrina Turquotte. Kaif has seven siblings; a brother and six sisters. From Hong Kong, she and her family moved to China, then to Japan. From there she went to France when she was 8, and thereafter lived for a few months at a time in Switzerland, Poland, Germany, Belgium, and other European countries. Then she moved with her family to Hawaii, and eventually to her mother's home country of England. Although it is often assumed that Kaif is from London, she lived there only for three years before finally moving to Mumbai.
