Duplicate meta tags will not affect rankings directly, but the click through rate will suffer due to ignored site pages. The target visitor will not attempt to click your site because of redundant descriptions.

Duplicate is never good. Always have them unique.

Yes mate! This is very effective for ranking and never make copy past on that. Thanks

It is not a good SEO practice that you have duplicate Meta description for the different page.
Duplicate meta description indicates that your site has more than same page and content inside your site.
Google can penalize your site and not indexed the site.

So define the Meta description for each page unique, concise and puts your keywords properly.
Because it is effective to get traffic and rank in Search Engine Result Page.

Thanks
