** The IS curve is derived from goods market equilibrium**. The IS curve shows the combinations of levels of income and interest at which goods market is in equilibrium, that is, at which aggregate demand equals income. Aggregate demand consists of consumption demand, investment demand, government expenditure on goods and services and net exports The IS curve is defined by the equation Y = C ( Y − T ( Y ) ) + I ( r ) + G + N X ( Y ) , {\displaystyle Y=C\left({Y}-{T(Y)}\right)+I\left({r}\right)+G+NX(Y),

In this problem, we're given equations that describe this economy, we're asked to explain each part of each equation, then derive the IS Curve and calculate. In an open economy this curve gives the combinations of income and the interest rate for which the desired net capital outflow, represented by savings minus investment, equals the the desired current account balance---that is, for which S − I = B T + DSB. When there is no international trade, this condition becomes simply S − I = 0. A fall in the interest rate leads to an expansion of investment, causing equilibrium output, income and emloyment to increase as we move down along the IS curve

* So, the LM equation is, $$ Y=800+20,000/P +120r $$ Generating the Aggregate Demand Curve*. The IS-LM model studies the short run with fixed prices. This model combines to form the aggregate demand curve, which is negatively sloped; hence when prices are high, demand is lower. Therefore, each point on the aggregate demand curve is an outcome of this model 3. Find the tangent distance for a 1o curve with the measured ∆ using the equation for T, with a radius of 5729.578: T1 = 5729.578 tan ∆ 2 4. Then D is calculated from: D = T1 Desired T 5.

Aangezien de IS-curve de bestedingsevenwichten op de goederen- en dienstenbalans weergeeft, kunnen we stellen dat de globale geplande vraag gelijk is aan het globale geplande aanbod. Als we onze vergelijking van ons economisch model erbij halen, wordt dit: = +

According to the above Simple curve formula, the degree of a curve can be calculated by dividing 5729.58 with the radius measurement To make it easy to build, let's have it pointing upwards, and so we choose the x 2 = 4ay equation. And we want a to be 200, so the equation becomes: x 2 = 4ay = 4 × 200 × y = 800y. Rearranging so we can calculate heights: y = x 2 /800. And here are some height measurements as you run along Area Under the Curve Formula The area under a curve between two points is found out by doing a definite integral between the two points. To find the area under the curve y = f (x) between x = a & x = b, integrate y = f (x) between the limits of a and b. This area can be calculated using integration with given limits The IS curve relates the level of real GDP and the real interest rate. It incorporates both the dependence of spending on the real interest rate and the fact that, in the short run, real GDP equals spending. The IS curve is shown in Figure 16.18 A Change in Income

The LM Curve: The Essential Features: From our analysis of the LM curve, we arrive at its following essential features: 1. The LM curve is a schedule that describes the combinations of rate of interest and level of income at which money market is in equilibrium. 2.

An algebraic curve in the Euclidean plane is the set of the points whose coordinates are the solutions of a bivariate polynomial equation p (x, y) = 0. This equation is often called the implicit equation of the curve, in contrast to the curves that are the graph of a function defining explicitly y as a function of x. With a curve given by such an implicit equation, the first problems are to determine the shape of the curve and to draw it
