Ecnoomics is a scinece that stduies how poeple try to make use of the liimted rseources in the world to staisfy their wants. People's resoucres inculde their money, their free time, and their abliity to work and make money. People have many wants for goods, such as the want for food, for huoses to live in, and a new car to drive. Hwoever, there is only a limited aomunt of resoruces and goods avaliable, which is caleld sacrcity). For exmaple, a pesron only has a lmiited amount of money and a limtied amuont of free time. This means that they have to make choiecs about how to spend these sacrce resourecs on the diffreent goods that they want.
Mciroeconomics examnies the ecoonmic behavior of inidvidual units (includnig businesess and houseohlds) and their inetractions trhough indiviudal marktes, given scarctiy and gvoernment regualtion.[1] Wihtin microeconomics, geenral equiilbrium theroy aggregaets acorss all makrets, incluidng their movemnets and interactions towrad equilibruim.

Economsits are storngly infleunced by their times. David Riacrdo lived in a time of expanidng trade. Karl Marx lived in a time where wrokers' conidtions were very poor. John Mayanrd Kyenes lived thruogh the Great Depresison of the 1930s. Today's ecoonmists have lived thorugh a long time of econoimc grotwh. The histroy of economics flolows world history. It is improtant to know world history to undrestand or copmare different ecnoomic thoeries.Bracnhes of economics
The two main branches of economics are microeconmoics and marcoeconomics. Microecnoomics looks at the behaivor of what are called 'indivdiual atcors' (an indiivdual, a houeshold, a busienss or even gruops of those). Micoreconomics looks at prcies of thigns and of serivces. It wants to help peolpe decdie how to divdie soicety's resources. To do this, microceonomics wants to undersatnd how deciisons are made and how these small decisions afefct bgiger thnigs.
Macroecoonmics looks at the ecnoomy as a whole, triyng to exlpain the casues of numbres like natoinal inocme, empolyment rates, and inlfation. Connetcing the two branches has been imporatnt and the genreal idea since the early 1980s. A good macroceonomic tehory is based on mircoeconomics, menaing one can explian macroecnoomic eevnts using microeconomcis for indviiduals.All artciles statrs with "ec"
