A Model of the Household's Demand for Durables and Energy
用一个简单模型，在确定性和不确定性下分析能源价格和财富对耐用品需求及其使用强度的影响，假设更换耐用品成本很高，因此耐用品的容量可能超过家庭需求。
Using a simple model, the effects of the price of energy and wealth on the demand for durables and their utilization are examined under certainty as well as uncertainty. This simple model is based on the assumption that the transaction costs involved in replacing the durable before it is obsolete are very high. Therefore it is possible that at times during the planning horizon, the optimal capacity (size) of the durable may exceed the household's needs. The static analysis results in each period depend on whether or not the household uses the durable at its full capacity.
