4 Motivation State capacity Many countries lack state capacity, despite large payoffs Weak states: argued to be the root of civil wars (Fearon and Laitin, 2003). Difference between economically successful and unsuccessful countries (Evans, 1995, Herbst, 2000, Besley and Persson, 2011, Acemoglu and Robinson, many others). Variation in state capacity related to many different factors: historical path dependence (Evans), ecology population density (Herbst), political economy (Besley and Persson, Acemoglu and Robinson).

5 Motivation But how does a state with low capacity build it? Paying for performance? Capacity is multi-dimensional: fiscal, bureaucratic, legal......and key: monopoly of violence. How should a state which lacks monopoly of violence acquire it? Imagine a political majority in favor of building capacity. Alvaro Uribe s presidential election in May To attain monopoly of violence could expand on: extensive margin (hire more soldiers), or intensive margin (make existing soldiers work harder). How to manage the intensive margin? One way is high-powered incentives. Brazilian Econometric Society ( ) How Not to Build a State Colombia s False Positives 5 / 68

6 Motivation This research Paying for performance in Colombia and its consequences We investigate high-powered incentives in the Colombian army. We show these incentives: 1 Are systematically related to murder of civilians portrayed as guerrillas killed, false positives, especially: 1 In units of military officers with pressing career concerns. 2 Where the judiciary is weak. 2 Created an incentive to corrupt the judiciary, hence eroding other dimensions of institutions. High-powered incentives can have very perverse effects. Innocents killed. Stronger military, but not consensually strong. Other institutions hurt. Hard to build state in one dimension. Complementary efforts in several dimensions are needed. Brazilian Econometric Society ( ) How Not to Build a State Colombia s False Positives 6 / 68

9 Context Introducing incentives Trends and regulation FP had long existed in Colombia, but more common in 2000s. Figure Increase coincided with incentives to fight insurgents: Law 782 of 2002: fund for intelligence operations and rewards to demobilized rebels. 2003: Democratic Security document announces system of rewards for information (regulated by decrees 128 of 2003 and 2767 of 2004). Other directives and decrees: Directive 029 of 2005 (and 015 and 016 de 2007): incentive scheme for informants leading to captures or killings. ( Secret documents not so secret). Decree 1400 of 2006 (Boina or Beret). Brazilian Econometric Society ( ) How Not to Build a State Colombia s False Positives 9 / 68

10 Context Introducing incentives Features of incentives: formal and informal Formally set a reward schedule for killings and capturing insurgents, seizing weapons and sharing information: 1 Military personnel was not explicitly excluded (also not explicitly included, except in Boina: up to one year salary), 2 No authorization ex ante by a superior officer required for operation, 3 Posterior intelligence could be used to justify the killings. Informal and unregulated incentives (see, e.g. UN Special Rapporteur): Days off when holidays approached, send to platoon on Sinai (foot soldiers). Medals, and promotions (commanders). Brazilian Econometric Society ( ) How Not to Build a State Colombia s False Positives 10 / 68

11 Context Removing incentives FP fall substantially in late 2008: media scandal after killing of several men from Soacha, near Bogotá. Government claimed victims were guerrillas killed in combat. Judicial investigations revealed this was not the case, and FP were widespread. Government issued new directives changing incentive structure: 1 Explicitly exclude rewards to military personnel. 2 Prioritize rewards to successful operations that did not involve killings (demobilizations, captures). 3 Require first investigation of combat-related deaths by judiciary. 4 Require prior intelligence for operations. Also ousted high-ranked officials involved in FPs and created special unit for FPs at Office of Attorney General.

12 Context False positives and career concerns The case of colonels Colombian army nearly tripled during 2000s some brigades commanded by colonels, not generals. Career concerns attached to new incentives more likely to affect colonels, who still can go up the military ladder. Captain Rozo Valbuena testimony against other officer: His only objective was to gather enough statistics to be able to be promoted to General. 27 soldiers expelled by platoon commander (a colonel) for not killing two people (dressed as civilians). Soldier description: When my colonel came in he started insulting us and scolding us, and told us that we were good for nothing, that we did not understand that a guerrilla member alive was useless for him, and that what mattered were killings because he was going to be promoted to general and that is how his performance was measured. He told us he was going to have us all expelled. Brazilian Econometric Society ( ) How Not to Build a State Colombia s False Positives 12 / 68

13 Context False positives and institutional weakness The case of weak judicial institutions The difficulty in controlling abuses reflects, and promotes, institutional weakness. Of the 1,056 cases of killings by armed forces that were assigned to the Fiscaĺıa (Attorney General) through April 2009, only 16 resulted in convictions (Alston, 2010, p. 13). Example: testimony from witnesses in case against Colonel Mejía Mejía had no trouble doing it because the local director of the Attorney General Office helped him with the setup When a person disappeared, his family members went to denounce it to the Police or the Ombudsman or any other institution in charge and, after this, the next victims where those denouncing.

16 A simple model Incentive scheme and agent utility A principal sets a linear incentive scheme. Focus on implications for agent, who exerts: good effort: a T q T (true positives), or bad effort: a F q F (false positives). Output linear in effort and noise ε J, independent and N(0, σ 2 J ): q J = a J + ε J, for J {T, F }, CARA preferences over wage w net of effort costs Ψ(a T, a F ), [ ] E e η(w Ψ(a T,a F )).

17 A simple model Technological complementarity or substitutability Effort cost: Ψ(a T, a F ) = 1 2 (c T a 2 T + c F a 2 F ) + δa T a F for δ c T c A Effort substitution, δ = Ψ a T a F > 0: Extreme with specialization: δ = c T c A Ψ(a T, a F ) = 1 2 ( c T a T + c F a F ) 2. Technological complements, δ = Ψ a T a F < 0 Extreme with constant ratio: δ = c T c A Ψ(a T, a F ) = 1 2 ( c T a T c F a F ) 2.

18 A simple model Reported killings and wage Introducing misreporting and differential incentives Misreporting: α false positives can be portrayed by true positives. α: poor quality of local institutions. Reported true positives ˆq T : ˆq T = q T + αq F. Incentives: colonels payoff depends more on output. π: relative importance of output in the agent s wage. Flat salary t plus linear incentive s based on reported killings: w = (1 π)t + πsˆq T = (1 π)t + πs(q T + αq F ).

Provided risk aversion and output volatility are not too large (bound on ησf 2 ): u(at, a F ) > 0 α 2 u(at, a F ) > 0. α π Agent s are especially interested in reducing the quality of institutions when facing stronger incentives (high π).

26 Data and Empirical Strategy Data Measuring FP Source: Colombian Human Rights NGO CINEP. Compiles list of events of arbitrary executions of alleged rebels. Information on: date and place of recruitment and execution; victim presented as guerrilla or paramilitary; perpetrators from Army, Police, or Navy; battalion or brigade responsible. Alternative datasets are likely to be less accurate: Official counts based on investigations: underreporting or geographic bias related to state capacity. Counts from victims associations: criticized as overstating FP. Our data: 925 cases of FP involving 1,513 victims from 1988 to Brazilian Econometric Society ( ) How Not to Build a State Colombia s False Positives 26 / 68

50 The impact on true positives and institutions Impact on institutions Size of the effects Taking 2003 as the post year A one-standard deviation increase in Judicial Inefficiency implies an increase, relative to the pre-period,... about 1-2 percentage points higher probability of a FP occurring (FP dummy: average increase was from 0.7% to 7%)... about more false guerrilas killed (FP killed: average increase was from 0.02 to 0.13). A colonel rather than a general implies an increase, relative to the pre-period,... about 3 to 5 percentage points higher FP dummy... about 0.16 more FP killed... about 0.02 higher judicial inefficiency (Judicial inefficiency constant on average at 0.06).

52 Conclusions Conclusion: How Not to Build a State How does a State lacking the monopoly of violence acquire it? High-powered incentives to army members in the fight against the insurgency in Colombia: Are systematically related to false positives. Specially for military officers with career concerns & where state judicial institutions are weak. Created an incentive to corrupt other institutions. What do we learn from this? Building state capacity in one dimension is difficult, even counterproductive, when state is generally weak. High-powered incentives in this context can have very perverse effects. Complementary efforts in several dimensions at the same time are required. Brazilian Econometric Society ( ) How Not to Build a State Colombia s False Positives 52 / 68
