Piana, V. (2001.) “Gross Domestic Product.” Economics Web Institute. Retrieved March 17,2017 from the World Wide Web : http://www.economicswebinstitute.org/glossary/gdp.htm
This article summarizes Gross Domestic product by talking the expenditures , income and consumption in the economy . The author relates what makes the changes in GDP and why they are so important to the process in finding the GDP. In this article, there is a process of measurement to finding economic growth when figuring out the change in the GDP and where it fits in the economy .
An evaluation of this article and author is as follows. I find the author decently credible given what sources of information is included in their speech and also the source is

There are wider impacts on consumption, production and the economy as a whole . This source goes over the kind of impacts that immigration is a part of when it gets involved with the labor markets and increase the skill trade coming from another homeland to the U.S. This is textbook source from a Nationally known Academy in the Science ,Engineering and Medicine. I consider this to be valid and accurate even though I didn’t see any author name or owner . I found the text very dry but to the point so I din’t find any reason to not believe the source . There was publishing in 2016 so it is very accurate

There also is discussion of the theories , arguments, reviews of the concepts related to the government spending . In this article, there are countries that have shown significantly reduced government spending as a share of national economic output, this article does its share to analyzes the economic consequences of those radical changes in reforms.
The author is a libertarian economicist which studies and speaks on the social political reforms in todays literature. I would say this guy is more than credable for his work in the economy and writing about the ideas shaping government and economic concepts . With his work , I can better understand how the government spending works as well as to understand the arguments of spending to influence or shut down economic expansion . In 2005, this seems so long ago that it could be outdated but I was able to take away the conceptual ideas of government spending which is what I wanted no more no less.
