Sorry that I can only come up with an approximate solution. Hopefully, more capable people of TeX.SE will provide better solutions.
My c.tex is as follows.
\documentclass{article}
\usepackage[authorformat={and,firstnotreversed,abbrv},bibformat={compress},dota\
fter={bibentry}]{jurabib}
\begin{document}
\nocite{*}
\bibliographystyle{jurabib}
\bibliography{c}
\end{document}
My c.bib is as follows.
@incollection{Ahmed94,
author = {Ahmed, Bashir and J. Gregory Robinson},
year = 1994,
title = {Estimates of Emigration of the Foreign-Born
Population: 1980--1990},
booktitle = {Census Bureau Population Division No. 9},
}
@article{Akay17,
author = {Akay, Alpaslan and Olivier Bargain and Klaus
F. Zimmermann},
year = 2017,
title = {Home Sweet Home? Macroeconomic Conditions in Home
Countries and the Well-Being of Migrants},
journal = {Journal of Human Resources},
volume = 52,
number = 2,
pages = {351-373},
}

natbibis primarily a citation management package. As such, it does not govern how the individual entries in a bibliography are formatted. Instead of asking how you may achieve your formatting objective withnatbib-- to which there really is but one answer, viz., "it can't be done" -- it would be more promising if you mentioned a particular bib style you wish to work with and asked how it would have to be modified in order to achieve your formatting objective. – Mico Jul 22 '21 at 19:03
