Do Human Rights Trials after Transition Make Difference?Hunjoon Kim
University of Minnesota
AbstractThis research asks whether human rights trials have the capacity for improving human rights protection in transitional societies. The new dataset on human rights trials in the world (Kim; Sikkink and Walling) were used. Two-stage probit models were used to examine the possible endogenous relationship between domestic human rights trials and human rights practices. To model the spatial dependence across states, spatio-temporal lag variables were included. Contrary to the recent arguments made by realist scholars (Vinjamuri and Snyder 2003/4), human rights trials after transition lead to improvement in human rights protection. Moreover, both human rights trials and improvement turned out to have positive impact on other states within the same region, which is a possible sign of regional diffusion.
Research Question
Figure 1. Cumulative Number of States with Political Transition and Human Rights Trials
Background
Since 1974, 100 states have experienced transition from nondemocratic regime to democracy or armed conflict to peace.
By 2004, 40 states have used domestic transitional human rights trials to address past human rights violations.
Research Question
Do human rights trials improve human rights situation in countries that have gone through political transition?
Methodology
Two-Stage Probit Model
1. Estimate two reduced-form equations for (1) human rights trials and (2) human rights improvements.
2. Compute the linear predictors of two dependent variables and substitute them for the endogenous regressors in the structural equations.
3. Correct the bias in standard errors.

Findings and
Result
Findings and ConclusionDomestic transitional human rights trials improve human rights protection in transitional societies. However, improvement in human rights protection does not necessarily lead to the frequent use of trials.
The probability of using trials increases if countries with a same religion in the continent used trials in the previous year. Also, the probability of experiencing improvement in human right protection increases if states within an immediate region experienced improvement in the previous year. (Diffusion effect)
States are more likely to experience the improvement in
human rights protection in 2~3 years after the last
improvement. On the contrary, states are most likely to use
transitional human rights trials immediately after their
political transition or the previous use of trials. The chance
of using trials decrease as years since transition or years
since the last use elapse.

Complications Solutions
Inefficient and Incorrect Standard Errors
Asymptotically correct covariance matrix (Maddala, 1983)
Huber’s (1967) robust standard errors (clustering observations by states)
Duration Dependence
(Temporal correlation)
Cubic polynomial – t, t2, t3
(Carter & Signorino, 2006)
Spatial Correlation Inclusion of the regional precedents variable at year t-1 as the spatio-temporal lag variable.
Precedents(HRT) = W1 · HRT (NT×1) (NT×NT) (NT×1)
W1: spatial weights matrix1
Membership in the same continent and religion
w1ij=1, if state i at year t and state j at year t-1 share common continent and religion w1ij=0, otherwise
Precedents(HRI) = W2 · HRI (NT×1) (NT×NT) (NT×1)
W2: spatial weights matrix2
Membership in the same region (UN subregion)
w2ij=1, if state i at year t and state j at year t-1 share common region (UN subregion) w2ij=0, otherwise
Event Dependence
(repeated spells)
Inclusion of the number of previous events (sequence or count variable – n) as variables - n, n2, n3
