Water rates are designed to meet multiple objectives, typically resulting in tradeoffs among the objectives of economic efficiency, revenue sufficiency, and related revenue stability. Standard theory of natural monopoly is extended here to explain why long-run marginal cost (LMC) can be greater than both average cost and short-run marginal cost (SMC) for municipal water utilities. The distincti...

The integration of large amounts of distributed energy resources (DERs) as photovoltaic solar generation, micro-cogeneration, electric vehicles, distributed storage or demand response pose new challenges and opportunities on the power sector. In this paper, we review the current trends on: i) how consumers adopting DERs can self-provide energy services and provide other services at system level...

Fluorescence measurements and H/2H exchange experiments monitored by mass spectrometry have been applied to investigate the influence of the conserved disulfide bridges on the folding behavior and in vitro aggregation properties of the scFv fragment of the antibody hu4D5-8. A set of four proteins, carrying none, one, or both of the disulfide bridges have been compared regarding their stabilitie...

The present study was conducted in the lobbies of 16 Taiwanese urban hospitals to establish what contributes to the degree of noisiness experienced by patients and those accompanying them. Noise level measurements were then conducted by 15 min equivalent sound pressure levels (LAeq, 15m, dB) during daytime hours. The average LAeq itself was found to be poorly related to perceived noisiness. Lev...

Political corruption is a type of market failure. One area of public policy where corruption is relatively common is the contracting out of public services. Private firms can improve their chances of obtaining contracts by bribing politicians or public servants and funding political parties. In the same vein, firms can gain access to policy makers by hiring influential former politicians –a pra...

We recently identified FkpA by selecting for the increased yield of antibody single-chain Fv (scFv) fragments in phage display, even of those not containing cis-prolines. We have now investigated the properties of FkpA in vitro. The peptidylprolyl cis-trans-isomerase activity of FkpA was found to be among the highest of any such enzyme with a protein substrate, yet FkpA is not able to enhance t...

The regulation of monopolistic firms has been widely investigated in the economic literature. Particular emphasis has been placed on the relationship between the regulated monopolist and the regulator. The present work deals with problems that may arise from the presence of several regulators. If regulators have different objective functions, inefficiency is likely to arise. A theoretical model...

Negotiated settlements are a form of regulation of public utilities that is alternative or complementary to the conventional process of litigation. Since the early 1960s they have been seen primarily as a means of coping with a regulatory backlog and as saving regulatory processing time. More recently legal scholars and practitioners suggest that settlements better serve the needs of the partie...
