Note. OLS regression (absolute deviation, Models 1a, 2, 3a, 4, 5, and 6), logit regression (relative deviation; 1/0 refer to >10%/≤10% relative deviation between partners, Models 1b and 3b). The table shows standardized regression coefficients (beta values) for the OLS models and unstandardized regression coefficients for the logit models; t-values for OLS models and z values for logit models are given in parentheses. Education: High school refers to the Austrian school-leaving exam required for admission to university studies. Time spent together with the partner was measured in hours on a normal day. Talking about energy saving was measured on a Likert-type scale from 7 = daily to 1 = never. In annual car mileage as driver, seven outliers larger than 26,000 km were excluded from the analysis. Consistency models use household-level predictors; time spent together, talking about energy saving, and age refer to the sum of the answers of both partners. Accuracy models use individual-level predictors of the proxy-reporting person and standard errors clustered on households as the independent units of observation. OLS = ordinary least squares.
