+
+%% Main features of econ.bst.
+
+% "econ.bst" is a BibTeX style file for economics. It provids the following
+% features:
+
+% 1) The author-year type citation (you need "natbib.sty" as well).
+% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
+%    for a specific journal).
+% 3) Highly customizable.  You can easily customize reference style as you wish.
+% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
+%    (http://dx.doi.org/10.1257/aer.20161492).
+
+% Bug reports, requests and suggestions are welcome. 
+
+% For changelogs, see CHANGES.txt file.

+%% Main features of econ.bst.
+
+% "econ.bst" is a BibTeX style file for economics. It provids the following
+% features:
+
+% 1) The author-year type citation (you need "natbib.sty" as well).
+% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
+%    for a specific journal).
+% 3) Highly customizable.  You can easily customize reference style as you wish.
+% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
+%    (http://dx.doi.org/10.1257/aer.20161492).
+
+% Bug reports, requests and suggestions are welcome. 
+
+% For changelogs, see CHANGES.txt file.

+%% Main features of econ.bst.
+
+% "econ.bst" is a BibTeX style file for economics. It provids the following
+% features:
+
+% 1) The author-year type citation (you need "natbib.sty" as well).
+% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
+%    for a specific journal).
+% 3) Highly customizable.  You can easily customize reference style as you wish.
+% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
+%    (http://dx.doi.org/10.1257/aer.20161492).
+
+% Bug reports, requests and suggestions are welcome. 
+
+% For changelogs, see CHANGES.txt file.

+%% Main features of econ.bst.
+
+% "econ.bst" is a BibTeX style file for economics. It provids the following
+% features:
+
+% 1) The author-year type citation (you need "natbib.sty" as well).
+% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
+%    for a specific journal).
+% 3) Highly customizable.  You can easily customize reference style as you wish.
+% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
+%    (http://dx.doi.org/10.1257/aer.20161492).
+
+% Bug reports, requests and suggestions are welcome. 
+
+% For changelogs, see CHANGES.txt file.

+%% Main features of econ.bst.
+
+% "econ.bst" is a BibTeX style file for economics. It provids the following
+% features:
+
+% 1) The author-year type citation (you need "natbib.sty" as well).
+% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
+%    for a specific journal).
+% 3) Highly customizable.  You can easily customize reference style as you wish.
+% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
+%    (http://dx.doi.org/10.1257/aer.20161492).
+
+% Bug reports, requests and suggestions are welcome.

+%% Main features of econ.bst.
+
+% "econ.bst" is a BibTeX style file for economics. It provids the following
+% features:
+
+% 1) The author-year type citation (you need "natbib.sty" as well).
+% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
+%    for a specific journal).
+% 3) Highly customizable.  You can easily customize reference style as you wish.
+% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
+%    (http://dx.doi.org/10.1257/aer.20161492).
+
+% Bug reports, requests and suggestions are welcome. 
+
+% For changelogs, see CHANGES.txt file.

-%% Main features of econ.bst.
-
-% "econ.bst" is a BibTeX style file for economics. It provids the following
-% features:
-
-% 1) The author-year type citation (you need "natbib.sty" as well).
-% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
-%    for a specific journal).
-% 3) Highly customizable.  You can easily customize reference style as you wish.
-% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
-%    (http://dx.doi.org/10.1257/aer.20161492).

-%% Main features of econ.bst.
-
-% "econ.bst" is a BibTeX style file for economics. It provids the following
-% features:
-
-% 1) The author-year type citation (you need "natbib.sty" as well).
-% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
-%    for a specific journal).
-% 3) Highly customizable.  You can easily customize reference style as you wish.
-% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
-%    (http://dx.doi.org/10.1257/aer.20161492).

-%% Main features of econ.bst.
-
-% "econ.bst" is a BibTeX style file for economics. It provids the following
-% features:
-
-% 1) The author-year type citation (you need "natbib.sty" as well).
-% 2) Reference style used in economics papers ("econ.bst" is not a BibTeX style
-%    for a specific journal).
-% 3) Highly customizable.  You can easily customize reference style as you wish.
-% 4) You can use "certified random order" proposed by Ray ⓡ Robson (2018)
-%    (http://dx.doi.org/10.1257/aer.20161492).
