There are two other areas where some analysis of actions has been
necessary: command-logics and logics and theories of obligation. For
the former the best reference is Rescher's book (1966) which has an
excellent bibliography. Note also Simon's counterarguments to some of
Rescher's theses (Simon 1965, 1967). Simon proposes that no special
logic of commands is necessary, commands being analyzed in the form
`bring it about that p!' for some proposition p, or, more
generally, in the form `bring it about that P(x) by changing x!',
where x is a command variable, that is, under the agent's
control. The translations between commands and statements take place
only in the context of a `complete model', which specifies
environmental constraints and defines the command variables. Rescher
argues that these schemas for commands are inadequate to handle the
conditional command `when p, do q', which becomes `bring it
about that 
!': this, unlike the former, is satisfied by making
p false.
There are many papers on the logic of obligation and permission. Von Wright's work is oriented in this direction; Castañeda has many papers on the subject and Anderson also has written extensively (his early influential report (1956) is especially worth reading). The review pages of the Journal of Symbolic Logic provide many other references. Until fairly recently these theories did not seem of very much relevance to logics of action, but in their new maturity they are beginning to be so.
