Extra votes to signal loyalty: regional political cycles and national elections in Russia

Under the system of presidential appointments of regional governors, which existed in Russia from 2005 to 2012, gubernatorial loyalty to the central government and particularly governors’ ability to deliver satisfactory results to the ruling party in national-level elections were crucial to their likelihood of being reappointed to the next term. In this paper, we argue that governors, anticipating the relationship between loyalty and reappointments, attempted to deliver additional votes to the ruling party, and show that those attempts were subject to regional political cycles. Exploiting variation in the starting and expiry dates of Russian regional governors’ terms of office, we find that the winning margins for a pro-government party across Russian regions in national-level elections held between 2007 and 2012 were substantially higher when elections were closer to the beginning or to the expiration of a regional governor’s term. The effect is driven almost exclusively by the governors serving their first terms. However, for elections held between 1999 and 2004, when governors were subject to direct votes by regional constituencies, no similar effect is found. The results can be explained by, e.g., first impression and recency biases in appointment decisions. We then implement several exercises to identify the sources of the additional votes for the ruling party and demonstrate that governors, while unlikely committing electoral fraud, likely exerted effort to stimulate turnout among ruling party supporters. © 2019, Springer Science+Business Media, LLC, part of Springer Nature.This research was supported by a grant from the CERGE-EI Foundation under a program of the Global Development Network (GDN).

Precise Measurement of the Pi+ -> Pi0 e+ nu Branching Ratio

Using a large acceptance calorimeter and a stopped pion beam we have made a precise measurement of the rare Pi+ -> Pi0 e+ Nu,(pi_beta) decay branching ratio. We have evaluated the branching ratio by normalizing the number of observed pi_beta decays to the number of observed Pi+ -> e+ Nu, (pi_{e2}) decays. We find the value of Gamma(Pi+ -> Pi0 e+ Nu)/Gamma(total) = [1.036 +/- 0.004(stat.) +/- 0.004(syst.) +/- 0.003(pi_{e2})] x 10^{-8}$, where the first uncertainty is statistical, the second systematic, and the third is the pi_{e2} branching ratio uncertainty. Our result agrees well with the Standard Model prediction.Comment: 4 pages, 5 figures, 1 table, revtex4; changed content; updated analysi

Spin physics with antiprotons

New possibilities arising from the availability at GSI of antiproton beams, possibly polarised, are discussed. The investigation of the nucleon structure can be boosted by accessing in Drell-Yan processes experimental asymmetries related to cross-sections in which the parton distribution functions (PDF) only appear, without any contribution from fragmentation functions; such processes are not affected by the chiral suppression of the transversity function $h_1(x)$. Spin asymmetries in hyperon production and Single Spin Asymmetries are discussed as well, together with further items like electric and magnetic nucleonic form factors and open charm production. Counting rates estimations are provided for each physical case. The sketch of a possible experimental apparatus is proposed.Comment: Presented for the proceedings of ASI "Spin and Symmetry", Prague, July 5-10, 2004, to be published in Czech. J. Phys. 55 (2005

Precise Measurement of the Pion Axial Form Factor in the Pi+ -> e+ nu gamma Decay

We have studied radiative pion decays Pi+ -> e+ nu gamma in three broad kinematic regions using the PIBETA detector and a stopped pion beam. Based on Dalitz distributions of 42,209 events we have evaluated absolute Pi -> e nu gamma branching ratios in the three regions. Minimum chi^2 fits to the integral and differential (E(e+),E(gamma)) distributions result in the axial-to-vector weak form factor ratio of gamma = F_A/F_V = 0.443(15),or F_A = 0.0115(4) with F_V = 0.0259. However, deviations from Standard Model predictions in the high-E(gamma)/low-E(e+) kinematic region indicate the need for further theoretical and experimental work.Comment: 5 pages, 4 figures, 1 table, revtex
