Yes, there is some evidence that immoral behavior, as exemplified though political corruption, is bad for economic development. The body of literature is large and to the extent that I am familiar with it, some corruption can "grease the wheels" and hasten development. In general, massive amounts of corruption is seen as a serious hinderence to development.
Also, I think that the utilitarian ideal suggests that all else being equal, more wealth and consumption is better. This implies that economic development carries a moral weight. That is to say, an ethical society should develop economically, to raise the standard of living and reduce suffering.
