This paper measures the performance in terms of costs of Swiss drinking water utilities accounting for environmental factors. We estimate a translog stochastic variable cost frontier using two different techniques on an unbalanced panel of 141 water distri ...
The renewable and non-renewable exergy and CO2 costs of petroleum derived fuels produced in Brazil are evaluated using exergoeconomy to rationally distribute the exergy costs and the CO2 emitted in processes with more than one product. An iterative procedu ...
We propose a model of a firm's reversible investment decision with macroeconomic conditions based on optimal switching of a diffusion regime. The switching costs and the cash flow generated from the firm depend on a business cycle alternating via a Markov ...
Financial factors are central to the recent economic crisis. Most macroeconomic models treat banks and financial intermediation as a veil. These models are unable to account for the recent financial crisis and they cannot be used for policy evaluation. Fin ...
The aim of this paper is to propose for the first time a reconstruction scheme and a stability result for recovering from acousto-optic data absorption distributions with bounded variation. The paper extends earlier results in [3] and [5] on smooth absorpt ...
The costing of the CAMEA spectrometer as proposed, involving the prices of guides and shielding, the spectrometer itself and the key pieces of sample environment equipment needed to fulfill the science goals of CAMEA, is estimated at 19.519 M€, which shoul ...
Standard addition strips were prepared for the quantitative determination of caffeine in different beverages by electrostatic spray ionisation mass spectrometry (ESTASI-MS). The gist of this approach is to dry spots of caffeine solutions with different con ...
This paper contributes to the debate on the impact of accounting measurement rules for financial assets. We examine the association between fair value accounting for financial assets and market price volatility for nonfinancial firms in an experimental set ...
We present two variants of OMD which are robust against nonce misuse. Security of OMD---a CAESAR candidate---relies on the assumption that implementations always ensure correct use of nonce (a.k.a. message number); namely that, the nonce never gets repeate ...
This paper proposes an efficient modeling technique for transient electromagnetic analysis of a rectangular metallic enclosure with multiple apertures, using the surface equivalent principle (SEP) and integral equations. The SEP is used to replace the aper ...
