The dual crop coefficient (Kc) approach to estimate crop evapotranspiration (ETc) separately considers soil evaporation (E) and plant transpiration (T) by computing a soil evaporation coefficient (Ke) and a basal crop coefficient (Kcb), respectively, with Kc=Ke+Kcb. This approach may be more...

High resolution climate data, derived from the ENSEMBLES Regional Climate Models outputs, were used to assess the impacts of climate change on crop water and irrigation requirements and yield of winter wheat and tomato in the Mediterranean region. Data, based on the A1B emission scenario, were...

Water use concepts and performance descriptors that may be useful in defining conservation and saving of water are discussed with the aim of improving the overall performance and productivity of water use. New indicators are proposed which include consideration of water reuse and aim to assist...

We examine the additivity of stock-market expectations over different time intervals. When asked about a ten-year interval, survey respondents expect a stock-price change that is not equal to, but closer to zero than, the sum of their expectations over two shorter time intervals that cover the...

Growing evidence indicates that utility over time is different from utility under risk. Hence, measuring intertemporal preferences (discounting and utility) exclusively from intertemporal choices is desirable. We develop a simple method for measuring intertemporal preferences. It is...

Intertemporal choices are affected by both discount rate and utility curvature. We investigate how the two aspects of time preference are affected by the size of the total budget using an intertemporal allocation task. At the aggregate level as well as at the individual level, we find magnitude...
