What are the uses and limitations of the real GDP in economics?

Real GDP is a term that stands for real Gross Domestic Product. This is a macroeconomic measure that shows the inflation-adjusted value of goods and services produced in the United States. The real GDP transforms the money-value measure into a usable index that gives the nation's total output. You can also view real GDP as a measure used to calculate the economic growth rate based on the percentage change in quantities produced from one year to another. The GDP is always expressed in terms of base-year prices and it is sometimes known as the constant dollar GDP.


Uses of Real GDP


Real GDP is used to measure the value of goods and services within the context of inflation, which provides a more accurate account of changes in price level than nominal GDP. In practical terms, real GDP is useful in reflecting price changes from a base year while the nominal GDP is not. To calculate the real GDP, it is necessary to look at the economic output of two specific periods of time in which the average prices of goods are the same. Without the real GDP, such estimates could be artificially inflated.


Limitations of Real GDP


The greatest limitation of real GDP is the fact that it is an incomplete measure of the nation's standard of living. It is only capable of measuring output and sales for products sold on the legal market. Because real GDP is used in business cycle forecasts, those forecasts are only as accurate as the data that can be assessed. Missing or unreported market information limits the scope and accuracy of real GDP estimates. Real GDP is also unable to assess factors such as overall improvements in happiness and more specific aspects of economic welfare, such as the distribution of economic improvements among different segments of the population.

etymology - Origin of the greeting "Sweet dreams".

Does anybody know the etymology of the phrase "sweet dreams"? I tried googling but did not find anything satisfying. Is this a relatively new phrase of the modern world or has this been in use for some time? I think it's the latter one. Answer The OED has the interjection as "a farewell to someone going to bed" from the 20th century: 1908 Sears Roebuck Catal. 198/1 Tenor Solos..Good Bye, Sweet Dreams, Good Bye. But it goes back until at least the 19th and possibly 18th centuries. John Wolcot, writing under the pseudonym of Peter Pindar, used it in his poem "Orson and Ellen; A Legendary Tale" published in 1801: Also from 1801 in The infernal Quixote (Page 287) by Charles Lucas: In the March 1776 of The Universal Magazine was published "The Serenade. A Pastoral Tale. From the German of Gesner" , where the shepherd Daphnis watches over his beloved as she sleeps and sings: The same tale appears in 1776's as Idyl XI, " Daphnis ...

Is there a word/phrase for "unperformant"?

As a software engineer, I need to sometimes describe a piece of code as something that lacks performance or was not written with performance in mind. Example: This kind of coding style leads to unmaintainable and unperformant code. Based on my Google searches, this isn't a real word. What is the correct way to describe this? EDIT My usage of "performance" here is in regard to speed and efficiency. For example, the better the performance of code the faster the application runs. My question and example target the negative definition, which is in reference to preventing inefficient coding practices. Answer This kind of coding style leads to unmaintainable and unperformant code. In my opinion, reads more easily as: This coding style leads to unmaintainable and poorly performing code. The key to well-written documentation and reports lies in ease of understanding. Adding poorly understood words such as performant decreases that ease. In addressing the use of such a poorly ...

What are the similarities between the relationships of the characters in The Outsiders and Romeo and Juliet?

At first glance, it might appear as if the characters in  The Outsiders  by S. E. Hinton and  Romeo and Juliet  by William Shakespeare do not have much in common; however, when one isolates the core of the conflicts, it becomes clear that the relationships in both stories are rooted in rivalry and secrecy.  In both  The Outsiders  and  Romeo and Juliet , an overarching theme is rivalry. While   socioeconomic status separates the greasers from the Socs in The Outsiders , last names separates the Montagues from the Capulets, who appear to be relatively equal in terms of socioeconomic status. Due to these rivalries, there are instances of deadly interactions in both stories. In  The Outsiders , Johnny kills Bob (whether his actions were justified or not is debatable). In  Romeo and Juliet , Romeo kills Tybalt and Paris, and Tybalt kills Mercutio. These deaths have profound effects on the main characters. In Ponyboy's case, the Johnny's death and other events in the novel inspire h...
