'Macro economic science †Chapter 10: The Aggregate prerequisite/Aggregate furnish sit chain reactor * Keynesian Economics †Economists who cogitate on the brusque endure * John Maynard Keynes †their expireing encourage the originator of macro instructioneconomics as a part discipline from micro * Classical Economists †economists who focused on long- come off anesthetizes much(prenominal) as growth * Aggregate Demand counseling †government’s attempt to keep the entireness incorporate aim of spending in the sparing * Equilibrium Income †the take aim of income toward which the parsimoniousness gravitates in the short get because of the accumulative cycles of declining or increasing production * authorisation Income †the take of income that the frugality is technically adequate to(p) of producing without generating accelerating inflation * Paradox of Thrift †and assortment magnitude in savings can buoy summit to a decrease in expenditures, lessen railroad siding and cause a ceding back * Multiplier Model †the amaze that was meant to begin Keynesian economics * This model accent totality outturn fluctuations * Explored why those widening fluctuations generally would not lead to chaotic fluctuations in issue †slumps * Instead lead to smaller fluctuations †recessions * The AS/AD Model †aggregate add/aggregate inquire Is a pedagogical model †intentional to give a framework to prink thinking about macro economy * Does not focus on problems that bloodline out because of interactions between individuals * Consists of 3 carouses * Short-run aggregate submit (SAS) bring deal * Aggregate enquire (AD) thin * Long-run aggregate publish (LAS) bow †highest sustainable aim of production * The cost take aim of all goods is on the vertical axis and the aggregate fruit is on the horizontal axis * It is a historical model †starts at mavin p oint in time and says what ordain likely happen when changes affect the economy * Aggregate expenditures ( look at) †the sum of intake, investment, government spending, and solve exports †p. 234 * Discuss the historical development of macroeconomics * The depression began in the 1930s and lasted 10 long time * During he depression product signal skin by 30% and unemployment rose to 25% * This was the beginning of macro’s focus on the pick up side of economics * Keynes started asking what short run forces were causing the Depression and what society could do to damp them * This created the framework that focuses on short-run issues such as business cycles and how to stabilize getup fluctuations * By the 1950s, Keynesian economics had been recognised by most economists and taught almost all over in the US * In the seventies inflation became a serious issue which meant that the multiplier model was not in truth helpful * It assumed that the set train is fix ed * The standard model taught in macro then shimmyinged to the Aggregate Supply/Aggregate Demand (AS/AD) model * inform the sour to the aggregate make convolute and what performers shift the curve * Aggregate pick out (AD) curve †a curve that shows how a change in harm take leave behind change aggregate expenditures on all goods and services * It is downwardly-sloping The reasons for the downward slope atomic number 18 due to the: * invade rate depression †the feeling that a lower price train has on investment expenditures through the effect that a change in the price level has on interest rates †p. 234 * foreign effect †as the price level falls (assuming the exchange rate does not change), net exports will bear witness †p. 234 * silver wealth effect (real balance effect) †a fall in the price level will make the holders of money richer, so they buy more †p. 234 * The multiplier effect strengthens each of these effects * Multipl ier effect †the amplification of initial changes in expenditures †p. 235 * Shifts in the AD curve †means that at every price level, total expenditures check changed †p. 236 * Shift factors of aggregate drive: alien Income †recessions and expansions occurring in other countries cause demand for US goods decreases or change magnitudes respectively * substitution Rate Fluctuations †when a country’s currency loses value, relative to foreign currencies, demand for foreign goods decreases and demand for domestic goods step-ups; exports as well gain * Distribution of income †* Expectations †expectations of future railroad siding and future prices * Government Policies †spending indemnity, measure policy, etc †p. 238 * When consumption expenditures increase, the AD curve shifts to the right, when consumption expenditures decrease, the AD curve shifts to the left * apologize the shape of the short-run aggregate supply curve and what factors shift the curve †p. 39 * Short-run Aggregate Supply (SAS) curve †a curve that specifies how a shift in the aggregate demand curve affects the price level and real output in the short run, other things unending * The curve is upward-sloping which means that other things unending, an increase in output is accompanied by an purloin in price level * When aggregate demand increases, the price level rises * Two reasons that the SAS curve slopes upward, other things constant: * Upward-sloping curves in auction markets * Firms’ tendency to increase their markup when demand increases * The shape of the SAS curve reflects two different types of markets * The auction market †markets be by the supply/demand model * Posted-price markets †prices are set by the producers and change infrequently * Often called Quantity-adjusting Markets †markets in which firms answer to changes in demand primarily by changing production instead of changing th eir prices * Shifts in the SAS curve: †p. 239 qualifys in input signal prices, such as reward or supply cost * If input prices rise, the SAS curve shifts up, if input prices fall, the SAS curve shifts down * Change in the productivity factors of production * An increase in productivity shifts the curve down * A reduction of input costs per unit of output shifts the curve down * Changes in consequence prices of final goods * consequence prices are a shift factor because they are a component of an economy’s price level * When import prices rise the SAS curve shifts up * Changes in excise and sales tax income * higher(prenominal) sales tax shifts the curve up * How much will the curve shift: The percentage change in wages and other factor prices minus changes in productivity * If productivity rises by 3% and wages rise by 7%, we can expect that the price level will rise by 4% for a given level of output * Explain the shape of the long-run aggregate supply (LAS)curve ⠀ p. 241 * Long-run aggregate supply (LAS)curve †a curve that shows the long run relationship between output and the price level * The position of the LAS curve is situated by potential output * solely where to position the curve is somewhat in debate * The range is bounded by a high level of output and a low level of output and the LAS curve can be design of as being the mid-point of that range * The shape of the LAS curve * The LAS curve is vertical At potential output all resources are being fully utilized * A rise in the price level mean that the price of goods and factors of production, including wages, will rise * Show the effects of shifts of the aggregate demand and aggregate supply curves on the price level and output in two the short run and long run †p. 243 * Short run equilibrium is where the SAS curve and the AD curve intersect * If the AD curve shifts to the right * terms level will rise * rig will increase * If the SAS curve shifts up * Price level w ill rise * Output will decrease * Long run equilibrium is where the LAS and AD curves intersect * AD curve can only order price level, it has no effect on output * If the AD increases, price levels rise Explain how dynamic feedback effects can destabilize the economy †p. 246 * * Discuss the limitations of the macro policy model †p. 250 * Fiscal policy †changing government spending and tax policy is a slow care for * Changes cannot be completed in a timely fashion * Potential output cannot be measured accurately * numerous other interrelationships that the model does not take into account * Rate of unemployment fluctuates and is difficult to pretend * Falling asset prices and falling price level on expectations of aggregate demand * When there are pressures for price levels to fall there are also pressures for asset prices to fall\r\n'
