It depends on how big a difference you are seeing. The header for AIFF might be slightly bigger (even without metadata). It maybe that if the file previously had metadata even though you have deleted the space previously used might still be there but now empty.
Full specifications for the AIFF format are available here

The size difference I see are very minimal. For example, 37,248,668 bytes for the WAV file and 37,250,942 bytes for the AIFF file. Is this normal? And wile I'm at it, what is the difference between the given "size" (in bytes) and the given "size on disk"?

As you said the difference is ver small only about 2K, I would attribute this to small differences in the header.
With regards to size, and size on disk, this probably refers to the fact that while a file may be only XXX in size, it will use XXY on the disk because it has to use whole disk blocks, so even if it only use 1 byte in the last disk block which might be 1K in size it will be allocated that entire block.
