For the following example I'm getting Missing $ inserted... with regard to the \rho command:

a tangible benefit from acquiring positive reputation that is not captured within 
\citet{d05a}, in particular, it implies that in this setting \rho rises over time.

If you can use unicode-enabled engines such as XeTeX or LuaTeX, you can simply add the greek letter ρ into the document.

If you stick to tex of pdftex as engines, you can find a way by the inputenc package, for example here you can find some help.

In all cases, \(\rho\) or $\rho$ will give you a ρ in italics. If you need in upright shape, you can use the upgreek package for that.
