This paper investigates how stock market returns respond to economic policy uncertainty shocks. Based on the vector autoregression (VAR) analysis of monthly changes in index United States and CRSP value-weighted from 1985:M2 2012:M6, results show that negatively shocks first, fourth, fifth, eighth, night, tenth eleventh months. In addition, Granger causality Wald tests is helping predicting returns. Finally, time-varying OLS regression also predict negative

The parity-violating longitudinal analyzing power, Az, has been measured in pp elastic scattering at an incident proton energy of 221 MeV. result obtained is Az =(0.84 +/- 0.29 (stat.) 0.17 (syst.)) x 10^{-7}. This experiment unique that it selects a single parity violating transition amplitude, 3P2-1D2, and consequently directly constrains the weak meson-nucleon coupling constant h^pp_rho When this taken together with existing violation data, constants h^pp_omega can, for first time, both...

This study examines if economic policy uncertainty in the U.S. has any effect on returns stock markets BRIC (Brazil, Russia, India and China) countries. The current also investigates how market four countries respond to shock. Granger causality tests are performed determine cause markets. results show that negatively affect Brazil, Russia; this negative is statistically significant at 10% level for Brazil 1% Russia. Stock China affected by uncertainty; however, not significant. of becomes...

TRIUMF experiment 497 has measured the parity-violating longitudinal analyzing power Az in p→p elastic scattering at 221.3 MeV incident proton energy. This comprehensive paper includes details of corrections, some magnitude comparable to itself, required arrive final result. The largest correction was for effects first moments transverse polarization. addition result, Az=[0.84±0.29(stat.)±0.17(syst.)]×10−7, parity-violation experimental data base greatly improves constraints on weak...

Economic uncertainty is closely followed and analysed by businesses, policy makers academic scholars because the world economies have now become very interconnected more than ever. This study to examine a relationship between economic United States Europe. The results reveal long-run equilibrium (cointegration) in findings provide evidence of interconnectedness conditions State Europe line with international transmission spill-over literature.

This paper examines the impulse response function of economic policy uncertainty (EPU) and stock market returns in Eurozone. Using a vector autoregression analysis, this study explores how Eurozone's responds to uncertainty; feedback from is also examined. monthly data changes index on Eurozone 1993 2012, shows that respond positively statistically significant second, seventh eighth months. However, pooled OLS increase predicts lower returns. The results reveal strong market. are...
