Global Insight • Macroeconomics Datasets • provides data on national income accounts, balance of payments, foreign debt, exchange rates, money supply and employment - among other national level categories. Also provides data on the IMF series and the OCDE series. • XLS format • Up to September 2004

  18. Getting familiar with data • Go to finance database website • http://finance.eller.arizona.edu/research/dataresources.aspx • http://www.ic.arizona.edu/ic/trombley/ • http://www.ic.arizona.edu/ic/trombley/dbdocs/ibes.html • Go to finance server Z drive • Get database manual

  19. Where to get help? • WRDS: http://wrds.wharton.upenn.edu/support/dataoverview.shtml • CRSP, Compustat and IBES documentation • UA: www.ic.arizona.edu/ic/trombley/dbdocs/docs.html • WRDS: wrds.wharton.upenn.edu/support/docs/manual.shtml • Unix Programming • UA: www.u.arizona.edu • WRDS: wrds.wharton.upenn.edu/support/index.shtml • SAS programming • support.sas.com/onlinedoc/913/docMainpage.jsp • Fortran 77 or 95 programming • http://docs.sun.com/app/docs/doc/802-2998

  20. Unix of UA and WRDS • How to get account • finacct group • Email Mark at accounting department • Each account: 12 MB • WRDS: same username and password • Each account: 750 MB • Where to download SSH • http://www.u.arizona.edu/ssh/ • Help for programming in Unix • http://www.u.arizona.edu • http://wrds.wharton.upenn.edu/support/index.shtml

  21. WRDS • Request account • wrds.wharton.upenn.edu/wrdsauth/account_req.shtml • Our subscription • http://wrds.wharton.upenn.edu/mywrds/dslist_desc.shtml • CRSP • Compustat • ExeuComp • A lot of free data: Fama French factors, etc.

  22. Data Not Available Through WRDS • Finance server Z drive • Trade and Quote (TAQ) Data • Fixed Income Securities Database (FISD) • Global Insight (monthly and quarterly files) • SDC Mergers and Acquisitions Data • Unix of UA • IBES

  23. Some Common Data—Nowhere to Get • CRSP / Compustat Merged Database • Thomson Financial Institutional Ownership and Insider Trading Data • Compustat Bank and Utilities Data

  24. Database in WRDS • How to access? • Web Querying? • If files are too large, you may have to split • Unix of WRDS • Where is the data in Unix of WRDS • /wrds/crsp/sasdata (fortran C++ etc) • How to access data in Unix? • Download directly • SSH file transfer • Program to retrieve data • SAS • Fortran and C++

  25. Database in WRDS—Contd. • Where is sample program codes? • wrds.wharton.upenn.edu/support/dslist/dslist.shtml • Unix of WRDS • /wrds/compustat/samples • Free SAS viewer • www.sas.com

  26. How to SAS in WRDS? • Three Ways: • PC SAS • Remote Submit • Remote Library Services (RLS) • SAS in Unix of WRDS • Where to get help? • wrds.wharton.upenn.edu/support/index.shtml

  27. PC SAS– Remote Submit • Where to get help? • wrds.wharton.upenn.edu/support/docs/wrdsSASConnect.shtml • Use WRDS server to remote execute SAS • Good for stupid old computers • Easily get disconnected • Not always so fast

  28. PC SAS—Remote SubmitSample Codes • %let wrds=wrds.wharton.upenn.edu 4016;options comamid=TCP remote=WRDS;signon username=_prompt_;rsubmit;libname comp '/wrds/compustat/sasdata';data mydata;set comp.compann;where yeara=2002;proc print data=mydata (obs=30);run;endrsubmit;

  29. PC SAS—Remote Library Services (RLS) • To use local libraries and remote libraries in the same time • SAS dataset in WRDS server and the dataset in your own computer • Your computer cannot be too old • It is in fact using your computer CPU and memory to execute program

  30. Sample Codes—RLS • %let wrds = wrds.wharton.upenn.edu 4016; • options comamid=TCP remote=WRDS; • signon username=_prompt_; • options linesize=72 nocenter nodate; • libname crsplib remote '/wrds/crsp/sasdata' server=wrds; • libname locallib 'c:\sas'; • data a; • set crsplib.msi; • where '01JAN2000'd <= date <= '31DEC2000'd; • run; • data b; • set locallib.msi_local; • where '01JAN2001'd <= date <= '31DEC2001'd; • run; • data c; • set a b; • run; • proc print data=c; • var date vwretd ewretd; • run; • signoff;

  31. SAS in Unix of WRDS • Write program and compile it • Use WRDS server, and is faster than UA Unix • Personal account: 750 MB • Nearly unlimited temporary capacity • /wrds/sastemp01-09 • Only 48 hours or even shorter

  32. Sample SAS—in Unix of WRDS • cp /wrds/crsp/samples/ina.sas my_ina.sas • sas my_ina.sas • How to read the results? • SAS viewer • File transfer to download to your local PC
