Additive and Multiplicative Uncertainty Revisited: What Explains the Contrasting Biases?

above the certainty level while for additive uncertainty the price should be lower than the certainty level. This note gives an intuitive explanation for the result after first presenting a parsimonious review of the two models. We also discuss which, if either, of the two models is more realistic.

日本主银行制度演变的路径分析

日本主银行制度源于战前的银行体制和二战期间的“军需企业指定金融机关”制度。战后，日本金融体制基本被保留下来，在日本经济恢复和高速增长期，日本企业与银行通过相互持股紧密结合起来，形成了企业和银行相互促进、共同发展的良性循环．但是，在20世纪90年代日本泡沫经济崩溃以后，紧密的银企关系加剧了企业危机与银行危机的连锁反应，导致银行与企业相互羁绊的恶性循环．

A consumer education programme based on the Transtheoretical Model of Change

MONEY 2000? is a successful consumer education programme that was implemented by Cooperative Extension personnel in over two dozen states of the USA between 1996 and 2002. One of the unique features of this programme is that it was based on the Transtheoretical Model of Change (TTM), a framework that has been widely used to study health‐related behaviour changes such as smoking cessation. This paper first describes how the MONEY 2000? programme was developed around major constructs contained within the TTM. Findings are reported from a survey conducted with participants in the first two states that delivered the programme. The findings suggest that several change processes used by MONEY 2000? participants are associated with specific stages of change. In addition, there may be differences in behavioural changes between participants who increased their savings and those who reduced their debts.
