Determinants of Customer Loyalty and Financial Performance

Abstract: Recent research in accounting advocates nonfinancial measures of company performance, such as customer satisfaction and loyalty, as useful indicators of aspects of firm performance. But what are the drivers of customer satisfaction and loyalty? We provide an integrated causal model of company performance in the personal computer (PC) industry that simultaneously tests links between product value attributes resulting from business process performance, customer loyalty, and financial outcomes. Our results extend prior accounting research (e.g., Banker et al. 2000; Ittner and Larcker 1998) in two directions: (1) by explaining the determinants of customer loyalty, and (2) by clarifying the relation between customer loyalty and measures of financial performance. We report that product value attributes directly and differentially impact levels of customer loyalty as well as prevailing average selling prices. Furthermore, measures of customer loyalty explain levels of relative revenue growth and profitability, a...

Relative risk of extinction of passerine birds on continents and islands.

Abstract: Greater numbers and higher proportions of recent species extinctions have been on islands rather than on continents. In contrast, predictions of massive future extinctions stem from the current clearing of continental, tropical forests1. For instance, since 1600, 97 out of 108 bird extinctions have been on islands2. However, 452 of the total 1,111 species currently considered to be threatened are continental3. Island flora and fauna are uniquely vulnerable to the human introduction of previously absent predators, diseases and other menaces4, whereas species on continents are not so ecologically naive. So could predictions of future continental extinctions based on island histories be exaggerated1? Most threatened species have small geographic ranges5, and the ranges of island species are inevitably smaller than those of continental species. For a given range size, how do the proportions of threatened island and continental species compare? Here we compile the ranges of thepasserine (perching) birds of the Americas. Corrected for range size, continental species are more—not less—likely to be threatened. We use this unexpected vulnerability of continental species with small ranges to produce a map showing where species losses might occur in the long term.
