Macroeconomics

‭●‬ ‭Balancing‬ ‭Perspective:‬ ‭While‬ ‭nominal‬ ‭values‬ ‭show‬ ‭the‬ ‭immediate‬ ‭state‬‭of‬‭the‬‭economy,‬‭real‬ ‭values give a more accurate and balanced understanding of economic changes.‬

‭In general, a real value is calculated by subtracting inflation from its nominal value:‬

‭Real value = nominal value − inflation‬

‭Real vs. Nominal Gross Domestic Product‬ ‭In‬‭the‬‭world‬‭of‬‭economics,‬‭adjusting‬‭GDP‬‭for‬‭price‬‭index‬‭changes‬‭is‬‭a‬‭crucial‬‭practice‬‭that‬‭allows‬‭us‬‭to‬ ‭decipher‬ ‭the‬ ‭true‬ ‭economic‬ ‭growth‬ ‭and‬ ‭understand‬ ‭how‬ ‭inflation‬ ‭or‬ ‭deflation‬ ‭impacts‬ ‭our‬ ‭economic‬ ‭landscape. Let's delve into this process and its core components:‬ ‭●‬ ‭Nominal‬‭(Current)‬‭GDP:‬ ‭When‬‭we‬‭talk‬‭about‬‭the‬‭nominal‬‭GDP,‬‭we're‬‭referring‬‭to‬‭the‬‭value‬‭of‬‭all‬ ‭goods‬ ‭and‬ ‭services‬ ‭produced‬ ‭within‬ ‭a‬ ‭nation's‬ ‭borders,‬ ‭measured‬ ‭using‬ ‭the‬ ‭actual‬ ‭market‬ ‭prices‬‭that‬‭exist‬‭at‬‭that‬‭specifc‬‭time.‬‭It's‬‭a‬‭snapshot‬‭of‬‭economic‬‭output‬‭at‬ ‭current‬ ‭price‬‭levels.‬ ‭However,‬ ‭it‬‭can‬‭be‬‭a‬‭misleading‬‭impression‬‭of‬‭how‬‭well‬‭a‬‭country‬‭is‬‭doing.‬‭This‬‭is‬‭because‬‭the‬ ‭value‬ ‭of‬ ‭nominal‬ ‭GDP‬ ‭can‬ ‭increase‬ ‭not‬ ‭because‬ ‭more‬ ‭goods‬ ‭and‬ ‭services‬ ‭are‬ ‭produced,‬ ‭but‬ ‭simply‬‭because‬‭prices‬‭have‬‭increased.‬‭Recall‬‭that‬‭GDP‬‭measures‬‭the‬‭monetary‬‭value‬‭of‬‭output,‬ ‭not the volume.‬ ‭For‬ ‭instance,‬ ‭if‬ ‭50‬ ‭billion‬ ‭products‬ ‭are‬ ‭produced‬ ‭at‬ ‭an‬ ‭average‬ ‭price‬ ‭of‬ ‭$4,‬‭GDP‬‭will‬‭be‬‭$200‬ ‭billion.‬‭If‬‭the‬‭next‬‭year‬‭the‬ ‭same‬ ‭output‬‭of‬‭50‬‭billion‬‭products‬‭is‬‭produced,‬‭but‬‭the‬‭average‬‭price‬ ‭rises‬ ‭to‬ ‭$5,‬ ‭nominal‬ ‭GDP‬ ‭will‬ ‭increase‬ ‭to‬ ‭$250‬ ‭billion.‬ ‭Therefore,‬ ‭to‬ ‭have‬ ‭a‬‭clearer‬‭picture‬‭of‬ ‭what is happening to output, nominal GDP is converted to real GDP.‬ ‭●‬ ‭Real‬ ‭(Constant)‬ ‭GDP:‬ ‭The‬ ‭real‬ ‭GDP‬ ‭takes‬ ‭a‬ ‭step‬ ‭beyond‬ ‭nominal‬ ‭GDP‬ ‭by‬ ‭accounting‬ ‭for‬ ‭changes‬ ‭in‬ ‭the‬ ‭average‬ ‭price‬ ‭level‬ ‭between‬‭different‬‭time‬‭periods.‬‭In‬‭other‬‭words,‬‭it‬‭reflects‬ ‭the‬‭economic‬‭output‬‭while‬‭keeping‬‭prices‬ ‭constant‬ ‭.‬‭Real‬‭GDP‬‭offers‬ ‭a‬‭truer‬‭representation‬‭of‬ ‭actual economic growth‬ ‭by eliminating the distortions‬‭caused by price fluctuations.‬ ‭Correcting GDP for Price Index (Nominal to Real GDP)‬ ‭To‬‭calculate‬‭the‬‭real‬‭GDP,‬‭we‬‭utilize‬‭the‬‭nominal‬‭GDP‬‭and‬‭a‬‭price‬‭index,‬‭which‬‭is‬‭typically‬‭measured‬‭by‬ ‭the‬‭GDP‬‭deflator.‬‭The‬ ‭GDP‬‭deflator‬ ‭is‬‭a‬‭measure‬‭of‬‭the‬‭overall‬‭price‬‭level‬‭in‬‭the‬‭economy,‬‭encompassing‬ ‭the prices of all goods and services‬ ‭produced, rather‬‭than consumed‬ ‭.‬

‭●‬ ‭Understanding‬‭the‬‭GDP‬‭Deflator:‬ ‭The‬‭GDP‬‭deflator‬‭measures‬‭the‬ ‭ratio‬‭of‬‭nominal‬‭GDP‬‭to‬‭real‬ ‭GDP‬ ‭,‬‭expressed‬‭as‬‭a‬‭percentage.‬‭This‬‭ratio‬‭reflects‬ ‭how‬‭much‬‭of‬‭the‬‭nominal‬‭GDP‬‭is‬‭inflated‬
