Yes - though not the installer is signed (inskcape doesn't use one btw - the DMG is not an installer), it's the application bundle itself. Newer versions of OS X include a feature called 'Gatekeeper' which checks apps which have been downloaded from the internet, as soon as the user attempts to launch them, and allows or blocks the launch based on whether they are signed or not. It was initially introduced as 'malware protection'. Developer IDs which can be used to sign applications are only available for registered Apple Developers. The membership costs 100$ per year.
