In this paper we develop and estimate a new-Keynesian model of inflation and use it to investigate the hypothesis that prices in the UK are re-set more frequently during periods of high inflation. In the model, firms are assumed to condition their expectations on an optimally-selected but incomplete information set and we further assume that the probability that they will reset their price in a...

The demise of the Old Telecoms Industry began in the mid-1980s when, due to different combinations of political-economic circumstances, the monopoly of telecoms was ended in the US, UK and Japan. By the late1990s, with the agreement of the European Union to fully liberalise its telecoms markets and the similar agreement of the WTO, there was a widespread consensus that the liberalisation of tel...

the beet armyworm, spodoptera exigua, is one of the most important pests of sugar beet in iran. the aim of this study was to determine the effect of water and nitrogen treatments of sugar beet planton developmental time and fecundity life table parameters of the pest. an experiment was carried out under laboratory conditions (25±2oc, 70±5% r.h. and 12l: 12d) on larvae reared on sugar beet leave...

The last decade has seen a growing interest in solver portfolios, automated solver configuration, and runtime prediction methods. At their core, these methods rely on a deterministic, consistent behaviour from the underlying algorithms and solvers. However, modern state-of-the-art solvers have elements of stochasticity built in such as randomised variable and value selection, tie-breaking, and ...

gypsiferous soils occur in xeric, ustic, and aridic moisture regimes. environmental conditions affect the mode of gypsum formation. gypsiferous soils in fars province, southern iran, are found in piedmont plains, flood plains, and alluvial plains. the objective of this work was to investigate the micromorphology of gypsum crystals formed under different soil moisture regimes. the results indica...
