Lorem Ipsum is <b>simply dummy text<b> of the printing and typesetting industry. Lorem Ipsum has been the industry's standard dummy text ever since the 1500s, when an unknown printer took a galley of type and scrambled it to make a type specimen book. It has survived not only five centuries, but also the leap into <a href="somesite.com"><b>electronic</b></a> typesetting, remaining essentially unchanged.
Do both elements place emphasis on the page its on or does one place more emphasis than another?
But today's algo is more holistic than the kind of "add up the scorecard" approach that search engines used in the -90s, so it's hard to give the kind of quantitative answer you seem to be asking for.
If you aren't yet familiar with Google's phrase-based indexing patents [webmasterworld.com], I suggest a bit of study.
[0042] ...grammatical or format markers, for example by being in boldface, or underline, or as anchor text in a hyperlink, or in quotation marks.[0133] ...whether the occurrence is a title, bold, a heading, in a URL, in the body, in a sidebar, in a footer, in an advertisement, capitalized, or in some other type of HTML markup.
A webmaster on this forum if memory serves recently said he was penalized by Google for bolding most if not all of an entire page.
I wouldn't bother using bold as a way to score ranking points. Even if Google gives it some value, it would be so minimal it may not even affect ranking. It has to be near the bottom of a long list of things Google uses to evaluate page or site value.
I don't think any of my webpages that use bolding for anchor text get penalized or helped (unless it overuses many other optimization techniques at the same time). I bold many text links but only for usability.
You're more likely to get penalized with the 950 penalty for overusing a particular word in text links on one page versus bolding all the links.
