Economic equilibrium is a condition or state in which economic forces are balanced. In effect, economic variables remain unchanged from their equilibrium values in the absence of external influences. Economic equilibrium is also referred to as market equilibrium.
Economic equilibrium is the combination of economic variables (usually price and quantity) toward which normal economic processes, such as supply and demand, drive the economy. The term economic equilibrium can also be applied to any number of variables such as interest rates or aggregate consumption spending. The point of equilibrium represents a theoretical state of rest where all economic transactions that “should” occur, given the initial state of all relevant economic variables, have taken place.
In economics, general equilibrium theory attempts to explain the behavior of supply, demand, and prices in a whole economy with several or many interacting markets, by seeking to prove that the interaction of demand and supply will result in an overall general equilibrium. General equilibrium theory contrasts to the theory of partial equilibrium, which analyzes a specific part of an economy while its other factors are held constant. In general equilibrium, constant influences are considered to be noneconomic, therefore, resulting beyond the natural scope of economic analysis. The noneconomic influences is possible to be non-constant when the economic variables change, and the prediction accuracy may depend on the independence of the economic factors.
Walrasian equilibrium
The first attempt in neoclassical economics to model prices for a whole economy was made by Léon Walras. Walras' Elements of Pure Economics provides a succession of models, each taking into account more aspects of a real economy (two commodities, many commodities, production, growth, money). Some think Walras was unsuccessful and that the later models in this series are inconsistent.
In particular, Walras's model was a long-run model in which prices of capital goods are the same whether they appear as inputs or outputs and in which the same rate of profits is earned in all lines of industry. This is inconsistent with the quantities of capital goods being taken as data. But when Walras introduced capital goods in his later models, he took their quantities as given, in arbitrary ratios. (In contrast, Kenneth Arrow and Gérard Debreu continued to take the initial quantities of capital goods as given, but adopted a short run model in which the prices of capital goods vary with time and the own rate of interest varies across capital goods.)
Walras was the first to lay down a research program widely followed by 20th-century economists. In particular, the Walrasian agenda included the investigation of when equilibria are unique and stable- Walras' Lesson 7 shows neither uniqueness, nor stability, nor even existence of an equilibrium is guaranteed. Walras also proposed a dynamic process by which general equilibrium might be reached, that of the tâtonnement or groping process.
Marshallian equilibrium
In partial equilibrium analysis, the determination of the price of a good is simplified by just looking at the price of one good, and assuming that the prices of all other goods remain constant. The Marshallian theory of supply and demand is an example of partial equilibrium analysis. Partial equilibrium analysis is adequate when the first-order effects of a shift in the demand curve do not shift the supply curve. Anglo-American economists became more interested in general equilibrium in the late 1920s and 1930s after Piero Sraffa's demonstration that Marshallian economists cannot account for the forces thought to account for the upward-slope of the supply curve for a consumer good.

Supply curve can not be negetively sloped when you made the second diagram the supply curve is wrong in that case.

[@simran_1506]

That is what she is talking about that the demand curve is intersecting the supply curve from below

[@MunawarHussain-ux8ls]

Impressive elaboration and productive content.

[@saraalizadeh1832]

Thanks. I'm looking forward to learning more about marshallian equilibrium

[@RanjithKumar-bd1ql]

Very nice lecture mam I proud of your lecture

[@economicspedia7096]

Glad to hear that

[@khumanthempoireiton5036]

15:39 so Marshallian is saying that as quantity increase price will fall. Wdf is going on

[@vickyingole5140]

Why is the supply curve downward slipping??

[@lyrixo]

That's what I'm thinking as well. The supply curve should be upward sloping to the right.

[@mxqueen7669]

Plzz make videos for economics optional paper for upsc mains...,it will be very helpful 🙏

[@dixitChaudhari-ue6zl]

This question came in 2021 upsc cse optional paper 1 question number 1

A request to you that please make separate Playlist of units.

[@nirajdayal]

Good

[@kuldeepdussad3621]

Mam supply curve ki shape aapane negative hi banaa rakhi hai?

[@aniketbhattacharya9256]

Good content…

[@elsageorge3787]

What rubbish. Supply curve galat banake itne confidently padha rahi hai

[@economicspedia7096]

I would ask you to go through your book and recheck once. Thank you so much for all the support.
