How entrepreneur applys behavioral economic strategy to do decisionBehavioral economics theories can also apply to assist any policy makers to make right and reasonable decision in right time. I shall indicate new principles to recommend and I also shall give any psychological cases to explain how policy makers can apply behavioral economic theories to judge how to make their any decision is the most right and the most reasonable.Behavioral economy is an independent and demonstrates real economic well-being. It aims to improve quality of life by promoting innovative solutions that challenge mainstream thinking on economic, environment and social issues. Also, behavioral economy is different branches of more alternative economies into a form that is useful primarily for policy-makers. I think behavioral economy can be given an aid to policy makers how who use economic tools to the broader policy making community by providing a theoretical behaviour for many policy approaches to be used. The standard economic analysis assumes that humans are rational and behave in a way to maximize their individual self-interest. This rational man assumption indicates a powerful tool for analysis. However, it has many shortfalls that can lead to unrealistic economic analysis and policy-making. Also, I think behavioral economics and psychology has these principles to influence human behaviour. These principles include, such as below: In common, people do many things by observing others and copying; people are encouraged to continue to do things when they feel other people approve of their behaviour. People do many things without consciously thinking about time. These habits are hard to change. There are cases where money is de-motivating as it undermines people's intrinsic motivation. People want their actions and commitments to be values usually. People put undue weight on recent events and who cann't calculate probabilities well and worry too much about unlikely events and who are strongly influences by how the problem/information is presented to them. People need to feel effective to make a change, even just giving who the incentives and information is not necessarily enough in any environment usually. So policy makers ought concern about these human behavior principles to judge whose behaviors are right or wrong, then who can decide to do any economic activities more reasonable, e.g. decisions of consumption, policies making, investment etc.In fact, much of our behaviour is strongly influenced by other people's behaviour. Social learning is a process by which we take in the behavior of others to learn how to behave. In more complex situations with which we are unfamiliar, we consciously watch and learn from the behavior of others. For example, when use a new library for the first time. When we mist make a conscious decision on how to behave, our sense of social identity is important, we think: how would other from my group behave in this situation? In situations where there is high social capital. i.e. where there are strong networks between people and a high level of mutual trust, so its seems other people's behaviour and our sense of social identity may be extremely important in influencing our own behavior and policy makers ought need to know how to judge their behaviour whether their behavior is either right and reasonable or wrong and unreasonabe in any learning process of environment. The standard economic theory is tried to explain where people's preferences come from, so it does not take account of the direct influence of the people's behaviour and social norms on our behaviour. The theory assumes we independently know what we want and that our preferences are fixed.
