The American Economic Association's Journal of Economic Perspectives can be accessed free of charge. It is definitely a reputable outlet (articles are mainly solicited from top economists), although it tends to publish original syntheses rather than primary research.
This happens all the time and is normal. Its due to measurement error. It is hard to measure these things in real time and as time goes by more data comes in which allows measurement of GDP and other macroeconomic variables to be better so they are revised. Sometimes the revisions can be quite large. Typically the latest data is also the least reliable.
Be more specific on what you need.
Quandl would be a pretty general source which hasn't been mentioned yet.
For macro data the St. Louis Fed is pretty good and thorough. Eurostat for European data. historicalstatistics.org for historical data.
Review of Economic Analysis
appears to be a respectable attempt (although I cannot tell about quality). It is peer-reviewed, and published by a private Italian - Canadian non-profit (with a lot of Greek names involved I have to point out), but it appears to have strong academic ties (for example, its Editor-in Chief, whose name I recognized since it so ...
I feel this barely qualifies as an answer, but doesn't Shiller have house prices data on his webpage? Currently here.
Historical housing market data used in my book, Irrational Exuberance [Princeton University Press 2000, Broadway Books 2001, 2nd edition, 2005], showing home prices since 1890 are available for download and updated monthly: ...
The Bureau of Economic Analysis (BEA) is the primary source for US economic data. Other US sources include the Dept of Labor, The Census Bureau, Dept of Commerce, and the US Energy Information Administration. Vizala combines data from a number of international sources. Other international sites/sources include The World Bank, UN Data Statistics Division, ...
Max Roser (2014) – ‘International Trade’. Our World in Data provides data on overall international trade growth during the requested time period, citing as their sources:
International Historical Statistics (by Brian Mitchell)
Correlates of War Bilateral Trade (as mentioned in the comments)
The Maddison Project (which I love)
The Rise and Fall of World ...
You have a few options for data. With questions of this nature, Quandl is your friend.
See here for historical gold prices, 1833 until present. I've not read about the methodology here though.
This resource has the gold/silver price ratio. Annual data. It seems pretty easy to transform this into price of silver.
It also looks like the Perth ...
@BB King's answer is good, but I want to make one point very clear:
The Fed did not change the data.
The Bureau of Economic Analysis revised the data as a part of its 2013 comprehensive revision process, which it engages in every five years using data from the most recent Economic Census.
It may be worth noting that the BEA, which is the agency that is ...
You could try searching the Harvard Dataverse for fileType:"R Data" like this: https://dataverse.harvard.edu/dataverse/harvard?q=fileType%3A%22R+Data%22
I think your use case of wanting to search for data in specific formats such as RData is a common one so I just created an issue about improving Dataverse to support this use case better: https://github.com/...
Quick answer, as I'm on my phone, but product by product input output tables can be obtained from Eurostat for EU countries, and are probably your best bet. Individual countries may have more detail from their own National Statistical Institutes' websites.
The production functions in these are derived under some fairly strong assumptions, though, and you'...
The Economic Bulletin is (among other things) an attempt to provide an open access alternative to Economics Letters. For authors, it has the additional advantage of not requirering submission fees (as Economic Letter does).
I don't know in details the extent of editorial content in the Economic Bulletin, but there is definitively some. I am far from a ...
I wanted to add two more journals focused on game theory, market, and institutional design :
These are new journal (the second is planning its first issue sometimes in 2016) but they are managed by serious people and are likely to become good references.
To answer your question of whether you can get a number for 'total home value,' the answer is no–at least not easily.
Zillow (somewhat) recently made available a data set similar to what you are searching for. I suspect, however, that they do not want the public to have access to aggregated value because it would showcase the volatility of Zillow home value ...
There have been several changes to the way the CPI is calculated over the years. A significant change occurred with respect to weights and hedonic adjustments in 1998 (I believe the pre-1998 series is what ShadowStats, without having any of the underlying data, attempts to replicate), and one in 1983 that, among other things, changed the way that housing ...
The IMF created its Historical Public Debt Database a few years back; that should do the trick for you. It's described in this paper, with annual data from 2012 back to as far as the late-1800s for some countries. You could pair that with the IMF/World Bank Quarterly Public Sector Debt statistics.
The OECD has nearly the exact data you are looking for. I haven't figured out how to get it into a raw data dump. I am pretty confident that this problem has more to do with me than it does with the data available.
The WTO holds similar quality information. I think somewhere a UK govt body is publishing this. Not sure where exactly though.
The UN has ...
One possibility would be to use Wolfram Alpha.
If I type the search phrase market capitalization msft 3rd December 2010 then the search engine returns the following:
If you use Wolfram Mathematica on your PC then you can import the data directly for processing using the FinancialData command (see here).
As I understand it, you're trying to estimate a demand system for different goods.
Have a look at Aguiar and Bils (forthcoming AER), who use the consumption expenditure survey to do exactly that. The previous link also contains their data and code.
From their abstract:
We do so by constructing an alternative measure of consumption expenditure, using ...
St. Louis Fed:
Has very good US data.
I am not aware of a database that systematically aggregates city-level data. I recommend state government sites and, for larger cities, city government sites.
Interestingly I could not locate quantitative data on Firing Costs (aka Separation Costs aka Severance Pay) for the US Economy. Perhaps because, as US Dpt of Labor says
There is no requirement in the Fair Labor Standards Act (FLSA) for
severance pay. Severance pay is a matter of agreement between an employer and an employee (or the employee's ...
Compustat Annual is used in Gabaix and Landier (2008). A famous stylized fact is the power-law distribution (by Gabaix again) of firm sizes. But power-law claims have been criticized as resulting from poor measurement.
