Firm Responses to Income Inequality and the Cost of Time

The full cost of shopping includes the cost of the shopper's time.When that cost increases, stores have incentives to respond in waysthat economize on shopper time. One response is to substitute in-storelabor for shopper time. Pooled cross-sectional tests using data fromsuburban and city food stores show that various labor intensitymeasures are higher where the opportunity cost of shopper time ishigher. We distinguish between income and cost of time effects byshowing that store labor intensity depends on the composition ofincome between male and female members of the family, and notonly on the level of family income. We obtain similar results for twoother ways that food stores can economize on shopper time – locatingcloser to the customer and offering more check out stations withina store. We also use a unique shopping time survey to showthat shoppers from higher income households make fewer visitsto food stores, spend less time per visit in the check out line andare more likely to shop at stores with longer hours.

Trade Liberalization and Productivity Growth

This paper presents a trade model with firm‐level productivity differences and R&D‐driven growth. Trade liberalization causes the least productive firms to exit but also slows the development of new products. The overall effect on productivity growth depends on the size of intertemporal knowledge spillovers in R&D. When these spillovers are relatively weak, then trade liberalization promotes productivity growth in the short run and makes consumers better off in the long run. However, when these spillovers are relatively strong, then trade liberalization retards productivity growth in the short run and makes consumers worse off in the long run.     

Equity and asset growth among Subchapter S banks

Since 2004, commercial banks in the United States have been allowed to elect Subchapter S (hence Sub-S) status with up to 100 shareholders. That limitation may promote more effective monitoring of bank managers by shareholders which can, in turn, explain previous findings of superior performance among Sub-S banks. The present research focuses on the possibility that the shareholder limitation also constrains opportunities for bank growth, or a slow growth hypothesis for Sub-S banks. Using a differences-in-differences regression approach for a sample of community banks (i.e., less than $1b in assets) from 2004 to 2014, and controlling for initial assets and urban location, it is found that annual growth in real assets and equity was significantly higher among banks that never held Sub-S status than for banks that always held Sub-S status, and that banks switching to Sub-S later grew significantly faster than those that always held Sub-S status. Fixed effects regressions show that switching to Sub-S status significantly reduced equity growth, with asset growth significantly reduced after 2008. In conjunction with earlier findings, the results suggest that the availability of Sub-S status helped to protect and strengthen community banks across a time period including substantial financial turmoil.     

Bank net interest margins,the yield curve,and the 2007–2009 financial crisis

Using quarterly call report data from 2000 to 2016, we reexamine the relationship between net interest margins (NIM) and the yield curve for more than 5,500 U.S. commercial banks. In the full sample, yield curve and RGDP growth have positive effects on NIM, while inflation and deposit‐to‐loan ratios (D/L) have negative effects. Splitting the sample around the 2007–2009 crisis, we show the impact of yield curve and RGDP growth on NIM increasing during the “recovery” (2009Q3 to 2016Q4), and inflation and D/L changing signs. Positive effects of yield curve on profits vary with bank size and change over time.     

Are consumers' perceptions of price–quality relationships well calibrated?

Past research has shown that, to varying degrees, consumers tend to believe price is an indicator of quality, even though there is in fact often very little correlation between objective measures of price and quality (PQ). Moreover, consumers have been observed to be poorly calibrated in their knowledge of precisely which categories exhibit the strongest association between PQ for products. Given the profound changes that have occurred in consumer markets, such as the rise of the Internet and the flood of product quality information now readily available online, the present work seeks to update this line of research. Specifically, it seeks to determine if changes in the marketplace have affected (1) consumers' perceptions of the PQ relationship; and (2) consumers' PQ calibration. Data from two sources were collected and compared: (1) Subjective ratings of the PQ relation for various common products, collected using a questionnaire format in a survey of 313 US consumers; and (2) Objective estimates of the actual PQ association of the same products, gathered from independent third‐party information providers who report both prices and rank‐ordered quality measures for each. Results indicate that consumers today (1) continue to perceive a modest positive relationship between PQ (more so for durables, less for non‐durables); and (2) are modestly calibrated for durable products. But they are much less well calibrated in the realm of non‐durables, where consumers expect a positive link between price and quality in precisely those product categories in which the relationship is actually negative. Relative to past research, the calibration of consumers has apparently ‘flipped’ from non‐durables to durables today. Potential explanations for this result include (1) the rise of the Internet as an information source for quality ratings of durables; (2) a higher level of perceived risk for durable goods purchases; (3) a greater tendency for durables to exhibit a positive correlation between actual quality and price; and (4) the rising quality level of private label brands, which may render prior price–quality perceptions for non‐durables outdated or obsolete.     

Animal foods and climate change: shadowing eating practices

Animal farming exceeds all forms of transport in terms of global greenhouse gas (GHG) emissions. Despite the implications of the seriousness of addressing animal farming in relation to mitigating the effects of GHG emissions, to date, the relationship between consumer behaviour and climate change has tended to neglect the role of animal foods. This paper reports on a pilot study in which six UK households were ‘shadowed’ to facilitate the investigation of the relationship between animal food practices and environmental practices, as they emerge in day‐to‐day life. Results indicate that most participants make no connection between the two issues at present, in terms of awareness or practice. However, animal foods do have an ambiguous and complex status in most participants' food practices; for instance, being viewed as problematic for reasons of health or animal welfare. This finding suggests that further research is needed into the potential for raising awareness of the link between animal‐based foods and climate change. This might have a role to play in shifting food practices towards more plant‐based, less GHG intensive, foods.
