In economic development, structural change among the three main sectors of an economy accompanies with aggregate economic growth. Nevertheless the question whether economic growth causes structural change or change in the economic structure causes aggregate growth is still unanswered. To shed some more light on this issue, this study examines a Grangercausality test in a panel environment to de...

A multifunctional panel concept is presented in which a lightweight, structurally efficient sandwich panel is able to undergo a reversible change in shape upon application of a localized thermal stimulus while supporting significant load. The shape change is effected by shape memory alloy face sheet elements, which exploit a ‘‘one-way’’ shape memory effect only. Unlike other related designs, no...

In most gravity model applications, general equilibrium effects are disregarded altogether or ”controlled for” by country or country-time fixed effects, and the parameter estimates on observable trade cost variables are falsely interpreted as reduced-form marginal effects rather than only direct effects of such variables on trade. This paper proposes an empirical approach which employs panel da...

Results of an analytical and experimental study to characterize the structural response of two compression-loaded variable stiffness composite panels are presented and discussed. These variable stiffness panels are advanced composite structures, in which tows are laid down along precise curvilinear paths within each ply and the fiber orientation angle varies continuously throughout each ply. Th...

We develop a stochastic frontier model with unknown locations and number of structural breaks for both efficiency and technology. The structural changes in technology and efficiency are different. It is possible to identify these two types of changes even under a short panel context. The algorithm to estimate the model is designed to avoid the potential pitfalls with panel data. Parallel comput...

The objective of this paper is to develop a GME formulation for the class of spatial structural equations models (S-SEM) into a panel data framework. In this respect, two innovatory aspects are introduced: (i) the formalization of the GME estimation approach of SEM to allow for spatial heterogeneity and spatial dependence (spatially sampled data); (ii) the extension of the methodology panel data.

the primary objective of this research is to evolve “a model for organizational intelligence in iranian universities”. based on the literature review, the dimensions and components of organizational intelligence in public universities were identified using expert panel opinions and delphi technique. a novel model for organizational intelligence in iranian universities is investigated by using d...

this paper studies the effects of the structural variables of the iranian industries sector on the welfare cost using to the structure-conduct-performance (scp) theory. in other words, we investigate the role of structural components and their effects on the size of the welfare cost in iran's industry sector. we have used the leibenstein's model to calculate the deadweight loss and then the pan...

this study investigates the relationship between market structure and profitability in the iranian manufacturing industries. in this study, raw data based on international standard industrial classification (at four digit code) has been used. fixed effects panel estimation method (based on diagnostic test results) has been chosen for empirical investigation. the result of the study confirms the...
