Consistency and Recovery in Retail Supply Chains

Practitioners and researchers describe inventory service level with metrics that communicate the likelihood of demand fulfillment without considering the ongoing capabilities of the supplier, for example, in‐stock and fill rate. We develop a method for measuring inventory service level that incorporates such supplier capabilities, namely consistency (the ability of a supplier to fulfill orders repeatedly) and recovery (the ability of a supplier to fulfill orders after a lapse in service). Using data from two retail supply chains, we illustrate our approach. To demonstrate the impact of consistency and recovery on supply chain performance, we model a retailer purchasing from competing suppliers with different levels of consistency and recovery. The model incorporates the retailer's uncertainty about demand and the retailer's uncertainty about its suppliers' service levels. We characterize how the retailer's orders and profitability change with a supplier's delivery performance through numerical experiments calibrated with field data. We find notable differences in market share across suppliers with similar traditional inventory service level metrics but differences in consistency and recovery. Further, we observe that a retailer can increase its profitability by determining orders via consistency and recovery in lieu of common metrics like in‐stock. Given the influence of consistency and recovery on supply chain outcomes, we discuss implications for practice and future research.     

In love with the debit card but still married to cash

Using shopping diary survey data, we show that changing payment patterns is a challenging task; even when consumers have fallen in love with a new payment instrument, they find it hard to divorce from their old payment instrument. We find a discrepancy between how consumers prefer to pay and how they actually pay. Half of the consumers who prefer the debit card to cash don’t use the debit card to pay a majority of their point-of-sale transactions. Our regression results show that the habit of paying cash plays a significant role explaining the presence of a gap.     

Wealth inequality: Theory,measurement and decomposition

This paper reviews the basic principles of inequality measurement, underlining the advantages and shortcomings of alternative measures from a theoretical standpoint and in the context of the study of the distribution of wealth. Adopting the two most popular measures, the Gini index and the P‐shares, the paper documents wealth inequality in Canada using the 1999, 2005 and 2012 Survey of Financial Security (SFS). It carries out several decompositions with covariates, featuring DFL‐type reweighting methods and Gini and P‐shares RIF regressions. The latter parallel decompositions deepen our understanding of how changes in socio‐demographic characteristics, including the compensating role of family formation and human capital, impact wealth inequality.     

A preliminary look at readmission and mortality among chronically critically ill and other medically complex Medicare patients

Chronically critically ill and other medically complex patients (CCI/MC-Ps) are those who are hospitalized with long-term intensive care needs and require extended periods of hospital-level care. CCI/MC-Ps may be at higher risk for readmission and mortality than other populations due to the severe nature their illnesses. This article examines factors that lead to increased probability of hospital readmission or mortality among CCI/MC Medicare patients. Logistic regression analyses are used to examine mortality and readmissions among the CCI/MC population. Numerous factors including length of stay in the acute hospital, age and gender affect whether a patient is readmitted to the acute care hospital within 90 days of discharge or dies within 60 days following a hospital stay.     

Family formation and economic insecurity among youth in South Africa

ABSTRACT

Youth unemployment continues to be a burden and concern for the South African government. Being economically insecure, the situation is dire with the government needing to provide resources to a population who should be economically independent. There is a need to look at the social determinants of economic insecurity among youth in South Africa. Family formations could either promote or inhibit economic well-being. This article aims to assess whether economic security improves as youth enter into unions and/or have children. The South African National Income Dynamics Study is used. Unmarried youth with no children are measured at baseline (2008) and followed up over time to examine whether economic security status changes as union status changes. Results show that while economic security, employment (from 7.61% to 25.67%) and net income per month (from 19.48% to 32.79%) increase over time, youth who marry but have no children have the lowest risk of economic insecurity (relative risk ratio?=?0.02, p < 0.05) compared with those who remain unmarried but have children. Special attention needs to be given to youth who have children and are unmarried and among those who marry and have children soon after.     

Agglomeration and the export decisions of French firms

This paper asks whether export spillovers influence the export behavior of French manufacturers. I use a database containing export flows by firm and importing country between 1986 and 1992. The decision to start exporting to a particular country is estimated using a logit model, controlling for the specific characteristics of firms, locations, countries and years. The export spillovers identified are industry- and/or destination-specific, and are computed at a very disaggregated geographical level. The results indicate that the pool of local exporters positively affects the decision to start exporting to a country. These effects are clearly destination-specific, and are larger for firms that export to remote markets.     

The implications of differing tourist/resident perceptions for community-based resource management: a Hawaiian coastal resource area study

Despite globally increasing interest in restoring local-level management of natural resources, few studies examine differences between residents’ and tourists’ place connections and implications for community-based natural resource management. This article reports findings from a survey (n = 264) in Haena, Kauai, Hawaii, where resource management is shifting from state-level government to local residents. Tasked with creating new, local-level rules governing use of coastal resources, Haena community members must consider the perspectives, resource use, and values of residents as well as of multiple, diverse user groups including the burgeoning tourist population. We found significant differences in how residents and tourists learn about the area; the activities in which they engage; their perceptions of resource health; who they think is responsible for caretaking of resources; and their views of personal responsibilities to the place. The findings have implications for local-level resource management and use of popular tourist destinations including the importance of guidebooks in mediating visitor perceptions of a place, the possibility of concurrent but separate visitor and resident use of the same area, visitors’ and residents’ sense of responsibility to mitigate impacts of their actions, and the potential of engaging residents’ place caretaking preferences toward more organized community-based resource management efforts.     

Reassessing Moral Legitimacy in Times of Instability

The presence of conflicting cues about what is legitimate provided by various stakeholders, begs the question of how the legitimacy of contested institutionalized practices is justified. Recent critique of tax minimization strategies exemplifies this difficulty: on one hand, practitioners need to increase shareholders' profits; on the other, a growing number of stakeholders push for ‘fairer’ corporate tax payments. Conducted during a time of public criticism of Australian corporate tax strategies, our study draws on justifications of corporate tax minimization strategies by senior tax practitioners and corporate submissions to a Senate Inquiry on corporate tax avoidance. The study explores how legitimacy judgements come under pressure by conflicting cues. Through the application of Boltanski and Thévenot's (2006) Economies of Worth (EW) framework, we advance legitimacy scholarship by clarifying what constitutes situated judgements in times of instability. Our work puts forward the concept of perceived forecasted consensus as a guide for individuals in making situated legitimacy judgements in times of instability.     

National minorities and their representation in social surveys: which practices make a difference?

This paper presents a systematic study of survey mechanisms that produce or reduce minority bias in social surveys. It extends the work of Lipps et al. (2011) who have demonstrated that, in the Swiss context, the more an ethno-national minority community differs, socio-culturally and socio-economically, from the national majority, the less it is likely to be represented in its proper proportion in the major national surveys. Minority bias furthermore has a vertical dimension: socio-economic bias against individuals from the most deprived backgrounds becomes extreme within ethno-national minority communities. Using data from the Swiss Labour Force Survey, the Swiss Household Panel, and the Swiss sample of the European Social Survey, in the present work we empirically assess the impact of three types of survey practices on minority bias: (1) strategies to increase overall response rates of the whole population indiscriminately from its minority status, (2) the use of pre- and post-stratification measures that take into account the overall share of foreigners in the national population, and (3) the conduct of interviews in a wider range of languages, in order to facilitate survey response among certain (linguistic) minorities. Our findings show that efforts to increase overall response rates can, paradoxically, create even more minority bias. On the other hand, they suggest that a combination of stratified sampling and a wider range of survey languages can have a positive effect in reducing survey bias, both between and within national categories. We conclude that measures that take into account and adapt to the social and cultural heterogeneity of surveyed populations do make a difference, whereas additional efforts that only replicate existing routine practices can be counter-productive.
