We examine the relationship between market structure and the persistence of US dollar-based sectoral real exchange rates for 14 OECD countries. Our empirical results based on disaggregated data suggest that differences in market structure significantly determine the rates at which deviations from sectoral purchasing power parity decay. Specifically, industries with a larger price-cost margin ar...

  Because of the piecewise linear nature of the data envelopment analysis (DEA) frontier, the optimal multipliers of the DEA models may not be unique. Choosing weights from alternative optimal solutions of dual multiplier models is one of the most frequently studied subjects in the context of DEA. In this paper, the authors have been inspired by the idea of Cooper et al. (2011) to propose a li...

Since 2010, and in line with austerity measures, public employment public-sector compensations to employees have been significantly reduced most Euro Area member states particularly Spain Greece. At the same time, unemployment these two economies was greatly increasing. In a dynamic stochastic general equilibrium (DSGE) model, we demonstrate that cuts wages are more damaging terms of output los...

The variation of circular microstrip antenna, a Sectoral microstrip antenna is discussed. The detail analysis to study the effects of antenna parameters like, feed point location and the substrate thickness for Sectoral angle increasing from 270 to 340 on the patch first four resonant modes is presented. The variation in angle tunes the spacing between three patch resonant modes which yields op...

Two alternative methodologies are compared for identifying common trends and cycles in a set of variables. One, following Harvey, uses an unobserved components structural time series model. The other, following Vahid and Engle, is based on a multivariate BeveridgeNelson decomposition. Both approaches are applied to a four sector model of output in the UK over the period 1970Q1-1993Q2, producing...

Middle-income countries are currently undergoing massive structural changes towards more industrialized economies. In this paper, we carefully examine the impact of these transformations on the environmental quality of middle-income countries. Specifically, we examine the role of sector value addition to GDP on CO2 emission nexus for middle-income economies controlling for the effects of popula...

‎in this paper‎, ‎we prove the nonexistence of two weighing matrices of‎ ‎weight 81‎, ‎namely $cw(88,81)$ and $cw(99,81)$‎. ‎we will apply two‎ ‎very different methods to do so; for the case of $cw(88,81)$‎, ‎we‎  ‎will use almost purely counting methods‎, ‎while for $cw(99,81)$‎, ‎we‎ ‎will use algebraic methods‎.
