Abstract
One-sided leniency policies and asymmetric punishment are regarded as potentially powerful anti-corruption tools, also in the light of their success in busting price-fixing cartels. It has been argued, however, that the introduction of these policies in China in 1997 has not helped fighting corruption. Consistent with this view, the Central Committee of the Chinese Communist Party passed on 23 October 2014 a Decision concerning Several Major Issues in Comprehensively Advancing Governance According to Law which stressed the current government’s strong commitment to fight corruption introducing heavier penalties but also severe restrictions of leniency offered to bribe-givers. Claims on the effects of the 1997 reform are not backed by data, to our knowledge, while evaluating the effects of a policy on crimes like corruption is difficult. These crimes are typically only observed if detected and convicted by the police, and an increase in observed convictions may as well be due to an increase in the total number of crimes rather than to a positive effect of the policy. We collected data on the investigations of bribery and public official corruption, available for most Chinese provinces for the period 1986-2010. The available evidence so far points to a substantial and stable reduction in the number of major corruption cases around the 1997 reform, a result per se ambiguous but consistent with a positive deterrence effect of the 1997 reform. Here we describe the planned case study analysis under way to corroborate and help the interpretation of these preliminary findings.

Primary Outcomes

Primary Outcomes (end points)
Share of cases initiated by the bribe-giver or by an innocent whitness. After the introduction of leniency, we should in general expect a higher frequency of cases in which the bribe-giver comes forth and reports the crime to the authorities. However this will also depend by the severity of sanctions and the actual likelihood of obtaining leniency in practice.

Size of the bribe, value of the favor exchanged, income or status of the bribe-giver (and the bribe-taker). If the reform, through the introduction of leniency, makes detection easier because of the incentives provided to the bribe-giver, this amounts to an increase in the expected fine (even aside the actual increase in sanctions) for the bribe-taker. We expect this to lead to an increase of bribe size: the threshold to unertake corrupt behavior is now raised, hence individuals will only exchange bribes if the returns from this corrupt agreement are higher. In other words, we expect cases of petty corruption to be deterred to a larger extent. In reading the cases we might nd some proxies of the value of the corrupt deal for the bribe-giver, or use as a proxy some measure of her income or status.

Experimental Design

Experimental Design
We select a sample of prosecution case files to be read and analyzed in detail. The total number is determined by a power calculation. A Chinese law student that we hired for the purpose will access all the documents related to the cases in the Procuratorates' archives, read through them and extract for us information about the outcomes that we specified.
