Judicial subversion: The effects of political power on court outcomes

Journal of Public Economics, 217 Doi: 10.1016/j.jpubeco.2022.104788 - Fulltekst i vitenarkiv

Are politicians in power treated more leniently in court? We show that Brazilian mayoral candidates charged with misconduct are 65 percent less likely to be convicted if they narrowly win the election. Politicians play no direct role in the judges’ careers, suggesting that formal independence does not completely insulate the judiciary from political influence. The effect is driven by districts with few judges and by judges with higher career instability.

Errors and monotonicity in judicial decision-making

Economics Letters, 215(110486) Doi: 10.1016/j.econlet.2022.110486 - Fulltekst i vitenarkiv

Recent literature raises concerns about monotonicity conditions required to interpret IV estimates under heterogeneous effects. A prominent example involves random decision-maker IV designs where decision-makers exhibit systematic differences in both preferences and skills. We develop tests of monotonicity in the context of judicial decision-making using proxies of judicial errors based on appeals and reversals of trial decisions from Norwegian court records. Our tests fail to reject average monotonicity. This suggests that differences in stringencies across judges are not sufficiently driven by skills to raise concerns about the validity of the random judge IV literature.

The dual approach for measuring multidimensional deprivation: Theory and empirical evidence

Journal of Public Economics, 177(September), s. 1- 12. Doi: 10.1016/j.jpubeco.2019.06.004 - Fulltekst i vitenarkiv

This paper is concerned with the problem of ranking and quantifying the extent of deprivation in multidimensional distributions of dichotomous deprivation variables. To this end, we introduce a family of measures of deprivation justified on the basis of dual social evaluation functions. Two alternative criteria of second-degree deprivation count distribution dominance are shown to divide the proposed family of deprivation measures into two separate subfamilies, which can be justified by a combination of correlation increasing and count neutral rearrangements. Based on EU-SILC data, we show that application of the proposed measures might lead to conclusions that differ from those attained by standard cut-off measures, and that results based on cut-off measures are more sensitive to the choice of specific measure.
