The electricity sector is the largest source of GHG emissions in the world, and reducing these emissions would often be costly. However, because electricity markets remain often only integrated at a shallow level (with different pricing regulations), many gains from deeper integration (adoption of marginal cost pricing everywhere) are yet to capture. This paper assesses the benefits of such dee...

We conduct a numerical analysis of bundling’s impact on a monopolist’s pricing and product choices and assess the implications for consumer welfare in cable television markets. Existing theory is ambiguous: for a given set of products, bundling likely transfers surplus from consumers to firms but also encourages products to be offered that might not be under à la carte pricing. Simulation of ‘‘...

Some recent literature has concluded that patent remedies result in systematically excessive royalties because of holdup and stacking problems. This article shows that this literature is mistaken. The royalty rates predicted by the holdup models are often (plausibly most of the time) below the true optimal rate. Further, those predicted royalty rates are overstated because of incorrect assumpti...

DiGeorge/velocardiofacial syndrome (DGS/VCFS) is a disorder caused by a 22q11.2 deletion mediated by non-allelic homologous recombination (NAHR) between low-copy repeats (LCRs). We have evaluated the role of LCR22 genomic architecture and PRDM9 variants as DGS/VCFS predisposing factors. We applied FISH using fosmid probes on chromatin fibers to analyze the number of tandem repeat blocks in LCR2...

A general problem in evolutionary biology is that quantitative tests of theory usually require a detailed knowledge of the underlying trade-offs, which can be very hard to measure. Consequently, tests of theory are often constrained to be qualitative and not quantitative. A solution to this problem can arise when life histories are viewed in a dimensionless way. Recently, dimensionless theory h...

An influential theoretical literature supports a discriminatory explanation for product bundling: it reduces consumer heterogeneity, sorting consumers in a manner similar to 2nd-degree price discrimination. This paper tests this theory and quantifies its importance in the cable television industry. The results provide strong support for the theory and suggest that bundling a top-15 cable networ...

In this paper, we studied some biological aspects of big eye scad (Selar crumenophthalmus) from Maldives. The fish sample was collected from the local fish market at Bangaa Faru, Male, Maldives. The length of the samples were ranged from 7.7 cm to 24.5 cm (mean value = 16.85 ± 2.82 cm) in fork length. Body weight ranged between 8 g to 255.6 g (mean value = 87.76 ± 40.41 g). The exponent values ...

With the increase in the number of urban highways constructed around residential and community areas around the city, has inevitably caused major noise pollution problems to city dwellers. The objective of the study was to assess the level of noise exposure and its impact to unfortunate residents residing around the vicinity of urban highways. Noise level recording was carried out at selected a...

This paper analyses optimal pricing for access to essential facilities in a competitive environment. The focus is on investment incentive issues arising from regulation under complete information. To that end, examining the provision of a natural monopoly infrastructure with unlimited capacity, it is shown that the fixed component of a regulated access price can be structured so as to induce a ...

A regulator anticipates learning about the relation between environmental stocks and economic damages. For a model with linear-quadratic costs and a general learning process, we show analytically that anticipated learning decreases the optimal level of abatement at a given information set. If learning causes the regulator to eventually decide that damages are higher than previously thought, lea...
