Introduction
Bribery
Bribes
I Likhoimstvo = taking bribes for doing bad stuff.I Mzdoimstvo = taking bribes for doing stuff youre supposed to do for free.
Problems
I First one obvious, ex-post verifiable.I Second one a transfer.I This paper: there are welfare implications for the second type of bribe.

Literature
Empirical Literature
I Exposure to corruption less investment, slower growth.I Corrupt economies are heavily regulated.I Putin is blamed for economic development, but not for corruption.
Theoretical Literature
I Stealing from governmental coffers is bad for development.I Rent-seeking is vacuous.I Bribes can improve the allocation.

I investor gets a random project, need to invest K, after investmentobserves return R, needs to pass an inspection.
I inspector asks for a bribe, if not paid does not pass the project.

I If investors have a signal about R before investment, almost the same story.I If inspectors have a signal about each project, need to be able to convince
the investor that he needs to pay higher bribe.

I Complaining to superiorsI Lowers the participation constraint.I Does not have to lower the bribe.I Total welfare should increase...

Discussion and Conclusion
ConclusionI Transfer bribery is not welfare-neutral.
I It might improve welfare when outside wage is low.I It might put the economy in a bad equilibrium, where not all projects start
up.
I Decentralization creates an inefficiency: bribe-takers cannot coordinate toswitch to a better equilibrium.
I Recovery rate higher bribe can go down (does not have to!)I There are some nontrivial implications for the size and efficiency of
government.I Not rent-seeking.I No strategic complementarities.
