Consumption vs. Expenditure
Full text linkStandard tests of the permanent income hypothesis (PIH) using data on nondurables typically equate expenditures with consumption. However, as noted by Becker (1965), consumption is the output of a home production' function that uses both expenditure and time as inputs. With this in mind, we revisit the retirement consumption puzzle by documenting that the dramatic decline in expenditures at the time of retirement is matched by an equally dramatic rise in time spent on home production. The innovation of our paper is that we empirically disentangle changes in actual consumption from changes in expenditures. To do so, we use a novel data set which collects detailed food diaries for a large cross-section of U.S. households. We show that despite the decline in food expenditures, neither the quantity nor the quality of food intake deteriorates with retirement status. However, unemployed households experience a decline in consumption commensurate to the impact of job displacement on permanent income. Taken together, the results on retirement and unemployment highlight how direct measures of consumption distinguish between anticipated and unanticipated shocks to income, while using expenditure alone obscures this difference and leads to false rejections of the PIH.
Restricting consumer credit access: household survey evidence on effects around the Oregon rate cap
Full text linkMany policymakers and some behavioral models hold that restricting access to expensive credit helps consumers by preventing overborrowing. The author examines some short-run effects of restricting access, using household panel survey data on payday loan users collected around the imposition of binding restrictions on payday loan terms in Oregon. The results suggest that borrowing fell in Oregon relative to Washington, with former payday loan users shifting partially into plausibly inferior substitutes. Additional evidence suggests that restricting access caused deterioration in the overall financial condition of the Oregon households. The results suggest that restricting access to expensive credit harms consumers on average.Consumer credit
The First of the Month Effect: Consumer Behavior and Store Responses
Full text linkPrevious research has used survey and diary data to carefully document that Food Stamp recipients decrease their expenditures and consumption of food throughout the benefit month, the beginning of which is defined by the date on which benefits are distributed. The reliance on survey and diary data has meant that researchers could not test two rational hypotheses for why food consumption cycles. Using detailed grocery store scanner data we ask 1) whether cycling is due to a desire for variation in foods consumed that leads to substitution across product quality within the month and 2) whether cycling is driven by countercyclical pricing by grocery retailers. We find support for neither of these hypotheses. We find that the decrease in food expenditures is largely driven by reductions in food quantity, not quality, and that prices for foods purchased by benefit households vary pro-cyclically with demand implying that benefit households could save money by delaying their food purchases until later in the month. The price effects are small relative to demand changes and relative to impacts found for other subsidy programs such as EITC, suggesting that most of the benefits accrue to the intended recipients particularly in product categories and stores where benefit recipients represent a small fraction of overall demand. We conclude by concurring with previous literature that food cycling behavior is most likely due to short-run impatience.
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
