Individuals behave differently when they know the objective probability of events and when they do not. The smooth ambiguity model accommodates both ambiguity (uncertainty) and risk. For an incomplete, competitive asset market, we develop a revealed preference test for asset demand to be consistent with the maximization of smooth ambiguity preferences; and we show that ambiguity preferences constructed from finite observations converge to underlying ambiguity preferences as observations become dense. Subsequently, we give sufficient conditions for the asset demand generated by smooth ambiguity preferences to identify the ambiguity and risk indices as well as the ambiguity probability measure. We do not require ambiguity beliefs to be observable: in a generalized specification, they may not even be defined. An ambiguity free asset plays an important role for identification.

This paper takes Suzhou Industrial Park as the research case, collects data through residents' questionnaires, and constructs a structural equation model to explore residents' satisfaction with "healthy house" and its influencing factors, in order to provide reference for better construction of "healthy house".The research draws the following conclusions: 1. Residents' overall satisfaction with the "health cabin" is 70.46%, which is relatively high; 2. The residents are highly satisfied with the blood pressure meter, temperature detector, opening time and frequency of the "Health House", but are less satisfied with the publicity work, lectures and propaganda activities of the "Health House"; 3. Policy factors have a positive impact on hardware environment satisfaction and hardware environment satisfaction; 4. Objective factors have a positive impact on software environment satisfaction and hardware environment satisfaction.
