This study attempts to measure the inefficiency associated with aggregate investment in a transitional economy. The inefficiency is decomposed into allocative and production inefficiency based on standard production theory. Allocative inefficiency is measured by disequilibrium investment demand. Institutional factors are then taken into consideration as possible explanatory variables of the dis...

Unlike most of the existing methods in Space Time coding (STC) system which focus on design of STC gaining full rate and/or maximum diversity, we propose an approach to improve spectral efficiency of the code. The proposed scheme carries more information symbols in each transmission block as compared to its counterpart code, and yet retains the property of simple decoding. Simulation results sh...

Motivation: Protein surface roughness is fractal in nature. Mass, hydrophobicity, polarizability distributions of protein interior are fractal too, as are the distributions of dipole moments, aromatic residues, and many other structural determinants. The open-access server ProtFract, presents a reliable way to obtain numerous fractaldimension and correlation-dimension based results to quantify ...

Various types of basic income schemes are considered to compensate the allocative inefficiencies induced by unemployment insurance systems. This paper develops a dynamic general equilibrium model of a unionized economy where participation to the labor market is endogenous and the budget of the State has to balance. It is shown that basic income schemes reduce the equilibrium unemployment rate. ...

Pakistan is home to one of the largest and most complex irrigation infrastructure systems in the world, consisting of 25 million hectares of irrigated agriculture, 56,000 kilometers of main canals, and tubewells in excess of 600,000. Nearly 100 million people depend on 107,000 water courses that are fed by 44 canal systems. Ineffective water management policies in the past have affected water a...

In the classic Crawford-Sobel (CS) model of strategic communication between an informed Sender and uninformed Receiver, perfect information transmission is never achieved as an equilibrium outcome. I present a modified version of the CS cheap talk game with the following two innovations: (i) both players take actions, and (ii) actions are strategic substitutes. In contrast to the CS setup, the ...

the aim of this research was to measure the relative efficiency of forest management plans in north of iran. in order to fulfill the research, data of 12 forest management plans were collected from the financial balance sheets of shafaroud forest company during a ten years period. first of all, basic data envelopment analysis (dea) models (bcc and ccr) were used to determine the efficiency. the...

In the year that capital-poor countries open their stock markets to foreign investors, the growth rate of their typical firm’s capital stock exceeds its pre-liberalization mean by 4.1 percentage points. In each of the next three years the average growth rate of the capital stock for the 369 firms in the sample exceeds its pre-liberalization mean by 6.1 percentage points. However, there is no ev...

Allocative inefficiencies in online auction markets can result in the loss of revenues for sellers. It can also cause frustration for buyers who fail to win an item despite placing bids higher than other winners. The main contention of this work is that allocative inefficiencies present arbitrage opportunities, though not strictly in the traditional financial market sense, where risk-free profi...

Ultraviolet-visible (UV-vis) and fluorescence spectroscopy have been used to characterize the polyelectrolyte complexes (PECs) formed when potassium indigo tetrasulfonate (ITS) interacts with poly diallydimethylammonium chloride (PDADMAC) through columbic attraction in the presence of the reducing agent sodium bisulfite, NaHSO3. The PDADMAC facilitates both the reduction of the ITS and the stab...
