We investigate mergers in markets where quality differences between products are central and firms may reposition their product lines by adding or removing of different qualities following a merger. Such materially from those studied the existing literature. Mergers without synergies exhibit product-mix effect which raises consumer surplus, but only when pre-merger industry structure satisfies ...

This paper aims to evaluate the impact of several indices of market structure including entry to barrier, economies of scale and concentration degree on 140 active industries using the digit. Accordingly, we apply three methods including cost disadvantages ratio ( ), Herfindahl–Hirschman concentration index ( ) and Comanor and Willson criterion in order to assess the economies of scale and usin...

The aim of this paper is to identify the industrial markets coordinates with the help of Herfindahl–Hirschman concentration index, cost disadvantage ratio (CDR) index and Comanor and Wilson's economies of scale index (MES). The paper also attempts to recognize Iran's monopolistic industries through the Fuzzy TOPSIS method presented by Chen (2000) under triangular fuzzy membership function. Give...

The standard economic price theory of working with efficient source allocation is being confronted a series empirical findings asymmetric responses. objective the research was to examine whether distribution prices within dairy chain in Czech Republic fair and farmers progressed collective approach strengthen their position supply chain. We used pre-cointegration cointegration test for asymmetr...

The purportedly irreconcilable aims of “area studies” versus formal disciplines are a long-standing concern. In reality, their objectives often inseparable, and approaches that start from center region have strongly contributed to theory building within disciplines. Few social scientists been so productive in bridges between these competing frames as James C. Scott, evidenced by his celebrated ...

Carlen showed that the Beckner-Hirschman entropic uncertainty principle, which is an improvement of Heisenberg's equivalent to a quantitative logarithmic Sobolev inequality involving entropy Fourier-Wiener transform. In this work, we identify sharp spaces and prove non-quantitative stability results for Wasserstein $L^p$ metrics. Inter-alia, new relating transform with Fisher information metric...

The land-use mix index is a way to quantify the mixture of patterns. Due practical limitations, few studies have highlighted validity indices. This paper aims explore potential characteristics indices using three-step screening method. data precision was concluded after first-step screening. A total 10 virtual blocks and 217 in Melbourne city center served as case study reflected various struct...

This article revisits and empirically tests the conjecture that specialization in natural resource industries (NRI) might not necessarily be a ‘curse’ for developing countries if it generates opportunities export diversification backward-linked sectors à la Hirschman. The systematizes evolution of debate around NRI ‘curse’. Then whether represent sufficient ‘domestic representative demand’ Lind...
