Increasing block tariffs seek a cross-subsidy mechanism between the water network users, based on the common assumption of weak water price elasticity. In Manaus, the capital city of the Brazilian state of Amazonas where most of the 1.6 million dwellers are supplied through the municipal water...

This paper analyses the effect of uncertainty on investment spending. We analyse twotypes of investment, i.e. aggregate investment and investment in energy saving technologies,using subjective evaluations of expectations and uncertainty of Dutch firms in 1997. Weestimate several models...

Given disparate beliefs about economic growth, technical change and damage caused by climate change, this paper starts with the seeming impossibility of determining a unique time profile of the social costs of carbon as a benchmark for climate negotiations and for infrastructure decisions that...

Three methods have been developed by the authors for solving optimal experimentation problems. David Kendrick (1981, 2002, Ch.10) uses quadratic approximation of the value function and linear approximation of the equation of motion to simulate general optimal experimentation (active learning)...

This paper estimates the probability distribution of budgets, revenues, returns and profits to G-, PG-, PG13-, and R-rated movies. The distributions are non-Gaussian and show a self-similar stable Paretian form with non-finite variance and non-stationary mean.

Since Kahneman and Tversky (1979), it has been generally recognized that decision makers overweight low probabilities and underweight high probabilities. Of the several weighting functions that have been proposed, that of Prelec (1998) has the attractions that it is parsimonious, consistent with...

Evidence shows that (i) people overweight low probabilities and underweight high probabilities, but (ii) ignore events of extremely low probability and treat extremely high probability events as certain. Decision models, such as rank dependent utility (RDU) and cumulative prospect theory (CP),...

The changing environment affects agriculture introducing sources of uncertainty. On the other hand, policies to cope with risks may have strong impacts on the environment. We evaluate the effects of public risk management programmes, such as subsidised crop insurance, fertilizer use and land...
