“…Several possibilities have been proposed by previous literature to solve this problem: (i) the introduction of instrumental variables in the OLS models in various stages (2SLS, 3SLS) [12,15,[32][33][34][35]; (ii) the application of maximum likelihood estimation methodologies [36][37][38][39]; and (iii) the use of OLS with Nordin's difference variable, which is sufficient to address this issue [40]. Nordin's difference variable is defined as the difference between the total bill and the cost if all units were charged at the marginal price, and it captures the impact of changes in intra-marginal prices on consumers' income.…”

Water is a key aspect for any tourist destination. The pressure of tourism on water resources, and specifically by the hotel sector on islands and coastal areas, threatens the sustainability of the resource and, ultimately, of the destination. Several international organizations propose price policy as an instrument to promote efficiency and penalize excessive water consumption. This study analyzes the short-term effectiveness of a water tariff reform, implemented by the regional government of the Balearic Islands in 2013, on hotel water consumption. The change consists in moving from a linear to an increasing block rate system. The study applies quantile regression with within-artificial blocks transformation on panel data for the period 2011–2015. The results conclude that the reform was not effective as a means to reduce the levels of water consumption. The disproportionate fixed component of the water tariff and the oversized initial block of the sanitation fee can explain the ineffectiveness of the reform.

“…In addition, SF and HM were developed considering consumption habits from different eras (Cortés 2008;Buchberger et al 2017). The daily cycle in water consumption has a close relationship with the weather factors that occur in a region (García et al 2004;Polebitski and Palmer 2010;Ghimire et al 2016), so the demand that can be generated at the domestic level, can vary between regions.…”

Water demand is a non-deterministic variable; current normative deliver different flow rates than might occur. Adaptations have been developed in different countries mainly for Hunter's method. The Hydro-Sanitary Standard 'Norma Hidrosanitaria Ecuatoriana' (NHE) 2011 in Ecuador proposes a demand calculation through a modification to the Norme Francaise NF P 40–202. This study proposes an adaptation to the Hunter’s Method using a binomial probability function, based on the disaggregation of time series of pressure and flow, during 62 consumption days, in different water meters, in academic facilities in Loja, Ecuador. Flow curves were developed based on consumption units, which gave very assertive values in relation to the maximum recorded flow rates. Also, in order to approach different estimation methods and since water consumption over time follows a Poisson distribution, synthetic series were generated using the Neyman Scott Rectangular Pulse Model (NSRPM), as this is the one that most adheres to the actual user behavior. Maximum flow rate was also determined with Water Demand Calculator (WDC) and NHE 2011 for comparison with NSRP and research results. Current research is an exploratory approach, has a methodological value for subsequent studies. Proposed Hunter's Method adaptation can provide an accurate flow estimation. Flows obtained with NHE 2011 method were closed to observed only in small facilities. NSRPM method showed an exactness high level, with only a 1.1% percentage difference compared to the measured one.

“…Second, in irrigation water consumption, the economic value of irrigation water was analyzed [6] and estimated using the residual imputation method in the Teesta River, Bangladesh [7], and Ohab-Yazdi and Ahmadi [8] used genetic-algorithm-based optimization model to evaluate the potential maximum net benefit of irrigation water. Third, in urban water consumption, Hester and Larson [9] used breakpoint and decomposition analyses to study changes in water use for three North Carolina cities between 1990 and 2014, and Ghimire et al [10] determined the price and income elasticity of household water demand under the unified water price.…”

a b s t r a c tWater is one of the essential resources to production and living. Agriculture, industry, and living are considered as the direct water consumption. This paper employs the concept of marginal product value to estimate the water consumption marginal benefits in Henan Province. We use data on agricultural water consumption, industrial water consumption, and domestic water consumption of 18 cities in Henan Province surveyed from 2006 to 2013 and considered the Cobb-Douglas production function. The results showed that, during the study period, except for the marginal benefit of agriculture in high developed area, the industrial and domestic water use increased, and the industrial and domestic water use benefits were much higher than agricultural. At the same time, the benefit of the developed area was higher than the developing area. The benefits of agricultural water consumption and industrial water consumption in high developed area have made great improvements gradually, while benefits in low developed area have made small changes; but the benefits of domestic water consumption presented the opposite trend. For the moment, the water consumption marginal benefit still has climbing space. The results are needed for determining the ways in which scarce water resources could be assigned to different areas and sectors.
