Abstract

It is often asserted that consumers undervalue future expected electricity cost relative to purchase price when they choose among different types of refrigerators, or equivalently that they have high “implicit discount rates” for expected future electricity cost. This chapter illustrates how this can be tested by measuring how much that the consumers are willing to pay in purchasing price in exchange for reducing the future electricity cost that has a present value of one unit of CNY, using the random utility theory and standard logit model. To carry out the research, apart from establishing appropriate model, China’s cross-provincial electricity pricing policies are systematically investigated, classified, and approximated in order to get national population-weighted average electricity price to compute electricity cost. The dataset contains all the transaction information of Chinese refrigerator market in the year 2013. The empirical result indicates that consumers are indifferent between spending one more unit CNY in discounted future electricity cost and saving 4.47 unit CNY in refrigerator purchase price. This result verifies that there is considerable energy efficiency gap in China’s refrigerator market suggesting the need of using government subsidy to encourage consumption of energy-saving electronic appliances, especially in the refrigerator market.

Notes

  1. 1.

    The phenomenon that products with energy-conserving technologies which are apparently cost-effective cannot quickly get enough market share is called energy efficiency gap, or equivalently, energy paradox (Jaffe and Stavins 1994).

  1. Remarks:
  2. 1. Average price is measured in CNY. It is the average of actual transaction price
  3. 2. Sales volume is the quantity of sales of refrigerators in China throughout the year 2013
  4. 3. Three volume values: total volume (total), cold-closet volume (cold-closet) and freezer volume (freezer) are measured in liters. Total volume is not equal to the sum of cold-closet volume and freezer volume
  5. 4. Daily power consumption (DPC) is measured in kilowatt-hour, also called “DU” in Chinese
  6. 5. Market share is computed as: \( Market\ share\ of\ refrigerator=\frac{Value\ of\ sales}{Total\ market\ sales}, \)
  7. 6. The data of brand, code, average price, sales volume and value of sales is provided by CRMC
  8. 7. The data of three volume values and power consumption are gathered manually from producers, online shops and database websites. Part of the data also come from researchers in Nanjing University of Information Science and Technology (NUIST)
  9. Stylized facts of refrigerator market dataset:
  10. 1. Total observation: 2757 refrigerator types
  11. 2. Average price of the refrigerator: 2464.97 CNY
  12. 3. Total sales volume: 31151637 refrigerators
  13. 4. Total value of sales: 76787744440.00 CNY
  14. 5. Average daily power consumption: 0.59 kilowatt-hour per day

  1. Remarks:
  2. 1. All prices in above table are measured in CNY per kilowatt-hour
  3. 2. First class limit is measured in kilowatt-hour per month
  4. 3. Population weight is computed using statistics of population at the yearend in 2013, provided by National Bureau of Statistics (NBS)
  5. 4. Time weighted average price and population-weighted price are calculated using the method in 3.2.3
  6. 5. National population-weighted average residential electricity price ≈ 0.502045319 CNY per kilowatt-hour
  7. Notes
  8. 1. Beijing is regarded as not adopting peak and valley pricing. The reason is that only households in the suburb of Beijing who do not use central heating but use electric heating are required to undertake peak and valley pricing. The proportion of this part of households is relatively low. For the time being, Beijing has been drafting unified pricing policies since 2014, but it still takes time to do make adjustments
  9. 2. Chongqing, Hunan, and Shanxi are regarded as using tiered pricing only. The electricity supplies of the three regions are dependent on adjacent hydroelectric power stations. The prices of residential electricity in these three regions are therefore highly flexible to change with variation of water flow caused by seasonal weather change. Thus, the discount and penalty adjustments of peak and valley hours are also flexible to change. It is difficult to get a consistent value. Therefore, we use the estimated average price computed by corresponding local Bureau of Commodity Price to approximate the true residential electricity price
  10. 3. Xinjiang and Xizang are regarded as neither using tiered pricing nor peak and valley pricing. This situation in the short run will not be changed since the power system in these two provinces is less developed
