The ground motion and damage caused by the 2015 Gorkha, Nepal earthquake can be characterized by their widespread distributions to the east. Evidence from strong ground motions, regional acceleration duration, and teleseismic waveforms indicate that rupture directivity contributed significantly to these distributions. This phenomenon has been thought to occur only if a strike-slip or dip-slip r...

During the Asian financial crises, interest rates were raised immediately, and then reduced sharply. We describe an environment in which this is the optimal monetary policy. ∗Northwestern University and Tilburg University. †Northwestern University, and NBER. ‡International Monetary Fund. §Braggion thanks the European Central Bank-Research Department for its hospitality.

The efficacy of a ready-to-use 5% dicyclanil pour-on formulation as a preventative of natural flystrike on Merino lambs was investigated in a field trial involving 5 sites in the southern Cape Province. A total of 1,804 lambs treated with dicyclanil were compared with 882 untreated control lambs for up to 25 weeks after treatment. Efficacy was assessed by calculating the weekly cumulative strik...

This paper analyzes collective bargaining using Spanish firm level data. Central to the analysis are the joint determination of wage and strike outcomes in a dynamic framework and the possibility of segregate wage equation for strike and non-strike outcomes. Conditional to strikes taking place, we confirm a negative relationship between strike duration and wage changes in a dynamic context. Fur...

One of the remarkable tectonic features of the Earth’s crust is the widespread presence of long, approximately straight and geomorphically prominent strike-slip faults which are a kinematic consequence of large-scale motion of plates on a sphere (Wilson 1965). Strike-slip faults form in continental and oceanic transform plate boundaries; in intraplate settings as a continental interior response...

using amplitude spectra and polarity (aspo) is a way for determining focal mechanisms of earthquakes. in the paper, the method has been used to determine the focal mechanism of zarand dahuiye earthquake dated 22 february 2005. the method uses frequency-wave number approach for calculating green functions and inverts full waveforms (from p arrival time up to the end of surface waves). at first s...
