For other locations of this guide, see the section titled "1.5 Where to Obtain This Guide" in part 2. 13.0 Software 13.1.0 Internet Software 13.1.1 Adobe Acrobat Reader [freely available software to read "PDF" files] Adobe Acrobat PDF (portable document file) files contain all the information needed to fully describe a document: fonts, graphics, and even colors. It is a very useful way to exchange files that have such features, such as working papers. The IRS even uses PDF files to distribute tax forms through the Internet. To read PDF files, you need an Acrobat "reader." Adobe makes readers available freely at this site (they generate revenue from the software that creates PDF files). It is easy to configure web browsers to automatically invoke readers when they encounter PDF files. # http://www.adobe.com/ 13.1.2 Ghostscript, Ghostview, and GSview [freely available software to read "PostScript" files] This set of freely available software lets you read PostScript and PDF documents on your PC, and print them. Ghostscript prints them, while Ghostview and GSview display them on your PC (Ghostview is for Unix platforms, and GSview is for Windows platforms; both require Ghostview). This software is freely available. # http://www.cs.wisc.edu/~ghost/ 13.1.3 Netscape [leading browser manufacturer] Netscape makes the leading browser for the Internet. Its use is now free for all users, and the source code is available as well for the next version. # http://www.netscape.com/ 13.1.4 Real Networks [leading audio-visual software] This firm provides the leading audio and video software for the Internet. Some versions of their "player" software are freely available, and many platforms are available. # http://www.real.com/ 13.1.5 uuencode/uudecode [enables binary files to be e-mailed] If you don't have access to e-mail "attachments" (which use a technology known as "MIME"), this pair of programs can let you e-mail binary programs and data. Uuencode takes a binary file (such as a word processing file or a program) and converts it to text so that it can be e-mailed. Uudecode than converts it back to binary. Using this pair of programs, researchers can collaborate by e-mailing binary data or word processing files. (If one host is an IBM mainframe, be sure to use the -x option.) # ftp://ftp.TeX.ac.UK/ctan/tex-archive/archive-tools/uue/ 13.1.6 WinZip [leading decompression program] This very useful Windows shareware utility can decompress most any type of compressed or archived file found on the Internet (this includes ".tar" and ".gz" files). The $29 price is money well spent. It also operates as "add-on" for browsers to decompress from files from the net -- they can thus be downloaded in one step. # http://www.winzip.com/winzip/ 13.1.7 xpdf [another PDF file viewer] Derek Noonburg has written a pdf viewer for systems running X Window as an alternative to Adobe's version. Versions for many Unix systems can be found here. # http://www.foolabs.com/xpdf/ 13.2.0 Software Program Libraries 13.2.1 Guide to Available Mathematical Software (GAMS) [guide to 9,000 numerical routines] This database contains information on almost 9,000 numerical routines from about 80 packages. It can be searched interactively in several different ways and is frequently updated. It is run by the U.S. National Institute of Standards. # http://gams.nist.gov/ # telnet://gams@gams.nist.gov 13.2.2 Netlib [leading archive for numerical software] Netlib is a numerical software library with approximately 50 megabytes of code. The routines, mostly in Fortran, are generally of high quality (many were developed at U.S. national labs or by professional numerical analysts). The popularity of Netlib is attested by the number of times it has been contacted -- at last count, nearly 23 million times. Packages include Linpack, Eispack, and their successor, Lapack (including a pre-release version in C), fftpack, the Harwell sparse matrix routines, Hompack, Lanczos, and Minpack. There are many other more specialized libraries. There is also code from various texts (but not Numerical Recipes), and code from the ACM Transactions on Mathematical Software (more than 500 different routines here alone). There are also many directories organized not by package, but by subject (each entry is code by different authors). Finally, there are various tools for Fortran and C users. In all, there are nearly 150 directories covering nearly every imaginable area in numerical computation. Any user of numerical methods would be well advised to be familiar with it. Netlib is available via e-mail, ftp, gopher, and the web. Introductory material on Netlib can be found in the first entries of the web, ftp, and gopher interfaces. For an e-mail. introduction, write "send index" in the body of a message addressed to one of the sites listed below, and in return you will receive general directions. You can search the contents of Netlib via e-mail (the method is explained in the e-mail directions) and via the web interface. The latter is more flexible, but you must carefully read the directions. The netlib2 ftp site, web and gopher sites contain uncompressed files. # http://www.netlib.org/ # gopher://netlib2.cs.utk.edu:70/1/ # ftp://netlib2.cs.utk.edu # Mail Site: <netlib@ornl.gov> # ATT Mirror: <netlib@research.att.com> # UK Mirror: <netlib@unix.hensa.ac.uk> # Norway Mirror: <netlib@nac.no> # Australia Mirror: <netlib@draci.cs.uow.edu.au> 13.2.3 CodEc: Code for Economics and Econometrics [general archive] CodEc, part of the NetEc, contains computer programs of interest to economists. Different hardware platforms, programming languages, and application languages are supported. They include C and C++, DOS and Windows executables, Fortran, Gauss, Mathematica, Matlab, Rats, Shazam, and Xlisp-Stat. In all, there are about 20 different programs and packages, some of which are quite extensive. For instance, it includes Hal Varian's Mathematica Notebooks for "Microeconomic Analysis," Matlab routines from Hansen and Sargent's "Recursive Linear Models of Dynamic Economies," routines from Estima (who produces Rats), Lin's "GAUSS Programming for Econometricians" (with routines for least squares, simultaneous least squares, arima models, and nonlinear optimization),Gary Langer's BCI Data Manager, Rizzo's GAUSS routines for Tobit and Probit models, King's maximum likelihood routines for GAUSS, C++ matrix classes by both Chris Birchenhall and Robert Davies, King's "count+duration" regression software, Haerdle's "XploRe" for nonparametric regression and data-analysis as well as other programs. Information on the programs is identified by "software information" files that identifies the author, a description, software required, etc. CodEc also provides links to other code archives as well as links to some companies that offer programs frequently used by economists. Dirk Eddelbuettel kindly helped edit this entry. # http://netec.wustl.edu/CodEc.html # http://netec.mcc.ac.uk/CodEc.html # http://netec.ier.hit-u.ac.jp/CodEc.html # Information: Dirk Eddelbuettel <edd@qed.econ.queensu.ca> 13.2.4 Econometrics Laboratory Software Archive (ELSA) [archives and tests software for economists] This site at UC Berkeley is partially funded by the NSF. It is designed to " facilitate the interchange of computational algorithms that have economic applications. In addition to serving as a central location for experimental software, we want to work with developers of algorithms, at Berkeley and elsewhere, to produce standards for documentation and testing that will facilitate the exchange of new methodologies and solutions to complex computational problems. Authors of software that have potential applicability in economics are encouraged to submit algorithms that conform to our documentation and testing paradigm." One unique aspect of ELSA is that where possible, code is tested, so users have some assurance of quality. Researchers can easily submit their code to the archive; they have detailed instructions on how to do so. The archive also includes some data, and they round out their collection with a section on "Manuals, FAQs, and Working Papers" in the field. # http://elsa.berkeley.edu/ 13.2.5 GAUSS Source Code Archive at American Univ.

Some of the default fonts for TeX and LaTeX do not work well with PDF. I understand an easier method on some systems is to use the "times" package (with the "usepackage" command in the header). # http://www.adobe.com/supportservice/custsupport/SOLUTIONS/543e.htm 13.4.2 MT and MTs [make tables for word processors from Stata or SAS output] This set of programs, by Jonah Gelbach, takes Stata (MT) or SAS (MTs) output and generates tables. Specifically, it takes Stata log files, or SAS .lst files, and generates tables in either LaTeX or ASCII (which of course can be imported into any word processor). An advanced version is in the works. # http://nber.org/~gelbach/ 13.4.3 TeX and LaTeX References [where to start with TeX & LaTeX] TeX is a typesetting system that was developed by the computer scientist Donald Knuth of Stanford. To make it easier to use, a very extensive set of TeX macros, known as LaTeX, have been developed. Versions of it are used widely, if not exclusively, for word processing in math and physics. In part, this stems from the ease in which one can type equations. In addition, LaTeX has an interesting philosophy: you design the logical structure of the document, and LaTex handles the physical output. This makes a number of things easier. For instance, if you wish to add a section, you don't have to retype all the other section numbers; LaTeX handles this automatically. Or, if you decide to change the presentation style of equations, you can make the change in one place, rather than equation by equation. For TeX, let me cite two references. The first one is the classic, while the second one contains information on the huge number of macros and ancillary programs for TeX. The TeXbook, Donald Knuth, Addison Wesley, 1984, ISBN 0-201-13447-0, paperback 0-201-13448-9 Making TeX Work, Norman Walsh, O'Reilly and Associates, 1994, ISBN 1-56592-051-1. For LaTex, let me also give two references. The first is the second edition of the classic LaTeX reference. It covers the new version of LaTeX, LaTeX2e. To be honest, I often find its technical appendix to be of more use than the chapters. The second reference is designed as a very detailed companion for the first.

Finally, the following URL is for the "TeX Users Group" (TUG), which offers a wealth of information on TeX and LaTeX. # http://www.tug.org/ 13.4.4 TeX Macros for Economics and TeX/LaTeX Sources [generate TeX in styles for different journals] Since I am not a TeX user, let me defer to George Greenwade <bed_ gdg@SHSU.edu>, who is. In fact, he is an expert. This section was written by George and I simply copied, with a bit of editing, from his posting to the Usenet newsgroup sci.econ.research as archived by Forrest Smith. The TeX macros written by Hal Varian, known as "VerTeX" (for Visualize Economic Reports in TeX; release 1.0 of August, 1987) are available for ftp retrieval from this site: Also, the command: "SENDME VERTEX" in the body of a mail message to FILESERV@SHSU.edu will retrieve the set of 19 files via e-mail. I have to stress that these are NOT LaTeX styles; they are TeX macros. VerTeX's syntax differs somewhat from the more standard LaTeX-type commands; however, the syntax used in VerTeX is consistent throughout VerTeX (and, as an occasional user, I feel comfortable in saying they are relatively easy to follow, understand, and use). The file set is pretty well documented and demonstrated. Varian has very roughly hinted that he might have an interest at some later date in rewriting these to use LaTeX and BibTeX (probably after the release of LaTeX3 -- since I am quite involved in that project, I feel safe in telling you not to hold your breath on LaTeX3; I'll be surprised if it's out before 1996). The present Visualize Economic Reports in TeX styles include: # jpe.sty --- Journal of Polemical Economy # jep.sty --- Journal of Economic Perspectives # jet.sty --- Journal of Economic Theorems # aer.sty --- Armenian Economic Review # ecnmet.sty --- Economagica # restud.sty --- Review for Economic Students # qje.sty --- Quartered Journal of Economics I'll assume that you can figure out which of these look like what "real" journals. When you use one of these styles, VerTeX will automatically adjust the style of the document and the style of the references to be more-or-less consistent with the journal style. Some fine tuning may be needed, but the output generally looks pretty good.

The results offer roughly the same functionality as PowerPoint: incremental display of material, embedded graphics, and even movies. # http://ricardo.ecn.wfu.edu/~cottrell/xdvi/
