April 2017A Strategy for Evaluating the Opportunity Cost of Time Estimates from New Choice Margins
with K.E. McConnell, V. Kerry Smith: w23349
Information frictions imply it is reasonable to expect the same commodity, in a given location, to sell for different prices at the same time. Aguiar and Hurst (AH) [2007] demonstrate how the search behavior implied by these price differences can be used estimate the opportunity cost of time. Their important insight allows the estimation of time prices over the lifecycle and the evaluation of the impacts of macro shocks on them. We provide the first assessment of the plausibility of this type of search behavior as a window on time prices. AH’s measures of the opportunity cost of time are shadow values that are jointly determined with individuals’ decision to search for bargains. Our analysis overcomes the challenges posed by this endogeneity by exploiting the complementarity between time a...
February 2015Individual Time Preferences and Energy Efficiency
with Richard G. Newell: w20969
We examine the role of individual discount rates in energy efficiency decisions using evidence from an extensive survey of U.S. homeowners to elicit preferences for energy efficiency and cash flows over time. We find considerable heterogeneity in individual discount rates. We also find that individual time preferences systematically influence willingness to invest in energy efficiency, as measured through product choices, required payback periods, and energy efficiency tax credit claims. Individual discount rate heterogeneity is in turn significantly related to characteristics of the individual and their household, including their financial situation. Individuals with less education, larger households, low income, and low credit scores had systematically higher discount rates, as did black...

July 2013Nudging Energy Efficiency Behavior: The Role of Information Labels
with Richard G. Newell: w19224
We evaluate the effectiveness of energy efficiency labeling in guiding household decisions. Using a carefully designed choice experiment with alternative labels, we disentangle the relative importance of different types of information and intertemporal behavior (i.e., discounting) in guiding energy efficiency behavior. We find that simple information on the economic value of saving energy was the most important element guiding more cost-efficient investments in energy efficiency, with information on physical energy use and carbon emissions having additional but lesser importance. The degree to which the current EnergyGuide label guided cost-efficient decisions depends importantly on the discount rate assumed. Using individual discount rates separately elicited in our study, we find that th...
