Green technology innovation is imperative to sustainable and environmentally sound economic development currently facing increasingly serious environmental threats. However, existing research has overlooked the uncertainties in policies. Based on logical relationship between regulation, policy uncertainty, green innovation, this study empirically analyzed quantitative among these three variable...

Many empirical studies have demonstrated large discrepancies between willingness to accept (WTA) and willingness to pay (WTP) measures. This paper examines the extent to which uncertainty about the environmental quality improvement can lead to a divergence between WTP and WTA measures. Indirect utility function parameters and uncertainty about the environmental quality change affect the extent ...

The precautionary principle, presented as a guide to environmental policy decisions in the presence of uncertainty, has been the subject of vigorous debate. However, the has generally not been discussed in relation to formal theories of choice under uncertainty developed as generalizations of the expected utility model. In this paper, it is argued that a formal basis for the precautionary princ...

The paper proposes a new communication system named SOBAR which employs environmental sensors for achieving human-robot interaction with physical world objects or environmental affairs. However, there is the uncertainty of human’s attention when he/she interacts with the objects. The uncertainty causes misinterpretation of sensor information. The mechanism resolves the uncertainty by drawing hu...

In many engineering applications, we have to combine probabilistic and interval uncertainty. For example, in environmental analysis, we observe a pollution level x(t) in a lake at different moments of time t, and we would like to estimate standard statistical characteristics such as mean, variance, autocorrelation, correlation with other measurements. In environmental measurements, we often onl...
