{"title":"Does the Effect of Incentives on Survey Response Rates Differ by Income Support History?","authors":"Juan D. Baron, Robert V. Breunig, D. Cobb-Clark, Tue Gørgens, A.

We find that an incentive improves response rates primarily amongst those individuals with the longest history of income support receipt. Importantly, these individuals are least likely to respond to the survey in the absence of an incentive. The incentive thus improves both average response rates and acts to equalize response rates across different socio-economic groups, potentially reducing non-response bias. Interestingly, the main channel through which the incentive appears to increase response rates is in improving the probability of making contact with individuals in the group with heavy exposure to the income support system.","PeriodicalId":331095,"journal":{"name":"Melbourne Institute: Applied Economic & Social Research Working Paper Series","volume":"26 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2008-04-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"125827735","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Jensen, Elizabeth Webster","doi":"10.2139/ssrn.886462","DOIUrl":"https://doi.org/10.2139/ssrn.886462","url":null,"abstract":"This paper examines the effects of market power and product differentiation on demand for grocery products in Australia over the period 2002 to 2005. We construct a model of the relationship between demand, market power and brand characteristics and then estimate the model using monthly data on price, quantity and volume sold for a bundle of 92 brands in 12 product categories from major supermarket stores across Australia. We also use data on the characteristics of each brand such as whether the product is environment-friendly, is a “private label”, or is made from recyclable materials. Our results suggest that firms are able to affect their demand curves through both product differentiation strategies and through market power.","PeriodicalId":331095,"journal":{"name":"Melbourne Institute: Applied Economic & Social Research Working Paper Series","volume":"2020 16","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2006-02-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"120848944","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
