We elaborate the recently introduced asymptotically exact semiclassical quantum gravity derived from the Wheeler-DeWitt equation by finding a particular coherent state representation of a quantum scalar field in which the back-reaction of the scalar field Hamiltonian exactly gives rise to the classical one. In this coherent state representation classical spacetime emerges naturally from semicla...

This paper documents patterns in international trade costs in processed foods for a large cross-section of developing and developed countries, during the 1976-2000 period. A trade costs index is inferred from a micro-founded gravity equation that incorporates bilateral ‘iceberg’ trade costs. For 2000, the weighted average tariff equivalent of trade costs ranges from 73% for the North to 134% fo...

Detection of subsurface structures by means of gravity method can be used to determine mass distribution and density contrast of rock units. This distribution could be detected by different geophysical methods, especially gravity method. However, gravity techniques have some drawbacks and can't be always successful in distinguishing subsurface structures. Performance of the gravity technique co...

We point out that extended gravity theories, the Lagrangian of which is an arbitrary function of scalar curvature R, are equivalent to a class of the scalar tensor theories of gravity. The corresponding gravity theory is ω = 0 BransDicke gravity with a potential for the Brans-Dicke scalar field, which is not compatible with solar system experiments if the field is very light: the case when such...

Gravity modelling has been used extensively in analysing trade flows but less so for crossborder investment. Recent theoretical work provides an underpinning for applications to FDI. In this paper we estimate a gravity model to evaluate the potential for increased FDI for a sample of Eastern European countries, following accession to the EU. Preliminary results suggest limited potential in manu...

ABSTRACT This article introduces students and new scholars to key issues in nonprofit accounting research. Three historic vignettes illustrate the role of internal controls legitimizing delegitimizing organizations. Building on these vignettes, I explore five topics: use reports mitigate principal-agent problems, caused by problematic measures, strategic reaction organizations being measured, d...

Today export diversification has become one of the most important economic objectives of development strategies in the developing countries. For various reasons, such as preventing instability in export prices of primary products in global markets, reducing fluctuations in exchanges of them compared with industrial goods, producing dynamic benefits resulted from exporting various goods and incr...
