Effects of Environmental Uncertainty on Information and Decision Processes in Banks
研究了41家独立银行的环境多样性和波动性如何影响其决策策略，发现多样性影响贷款处理流程，而波动性则与特定决策的不确定性相关。
This research was partly supported by a grant from the Bank Administration Institute. The effect of environmental diversity and volatility on decision-making strategies is examined for 41 independent banks. Uncertainty is defined and measured in terms of an entropy equation, which combines environmental and probabilistic sources of decision uncertainty. Uncertainty was associated with loan managers' perceptions of the uncertainty of loan repayments and the information they collected before deciding on a loan application. The normal operations procedures used by the banks to process loans varied with the diversity, but not the volatility, of their environment. Volatility was associated with the uncertainty experienced for particular decisions. A theoretical framework with the implication of the two sources of uncertainty is discussed.e
