Consumer Perceptions of Sustainability: A Free Elicitation Study

While sustainability has long been conceptualized as comprising three pillars (ecological, economic, and social), extant research and practice tends to focus on the ecological dimension of sustainability. Sustainable products and services are often marketed as a proxy for “environmentally appropriate” without considering other dimensions. As a result consumers may be under the misconception that sustainability is a one-dimensional concept and the way that researchers and marketers are employing this term may be perpetuating this (mis)understanding. This research explores the way that consumers interpret this construct. The results lend support to the argument that a one-dimensional operationalization of sustainability may be underestimating the importance of the social, economic, and time dimensions in consumer perceptions.     

The Determinants of Child Labour and Child Schooling in Ghana

This paper investigates the main determinants of child labourand child schooling in Ghana, with special reference to theirinteraction. The study provides evidence on the impact of povertyand quality of schooling on child labour hours, taking intoaccount their potential endogeneity. The exercise distinguishesbetween cluster poverty and household poverty in the two-stageHeckman estimation procedure. In addition, it relies on a setof non-common regressors to identify the child labour hoursregression from the selection equation. Other methodologicalfeatures include simultaneous equations estimation of childlabour, child schooling and poverty, taking into account theirjoint endogeneity. The empirical results contain some evidenceof sharp rural urban differences, thus, pointing to the needto adopt region specific policies in enhancing child welfare.However, rural, semi-urban and urban Ghana agree on the effectiverole that improved school attendance can play in curbing childlabour.     

International Poverty Comparisons on Unit Record Data of Developing and Developed Countries

Cross country poverty comparisons on unit records have, rarely, involved both developing and developed countries. The present study attempts to fill this gap by comparing poverty across fourteen nations with diverse economic and demographic characteristics and at vastly different stages of economic development. The study contains evidence on (a) cross country variation in the equivalence scales estimated in the presence of both household size economies and adult/child relativities, (b) impact of demographic adjustment of the poverty line, that incorporate household size and composition changes, on the poverty rates, and (c) sensitivity of the poverty estimates and their rankings to the ‘equivalence elasticity’. The study finds that country rankings based on per capita GNP bear very little resemblance with that based on the aggregate poverty rates. The latter hide substantial variation in the poverty estimates across different household types.     

An Intraday Examination of the Components of the Bid–Ask Spread

Using transactions data for a sample of NYSE stocks, we decompose the bid–ask spread (BAS) into order–processing (OP) and asymmetric information (AI) components using the techniques of George, Kaul, and Nimalendran (1991) and Madhavan, Richardson, and Roomans (1997). McInish and Wood (1992) demonstrate that the intraday behavior of BASs can be explained by variables measuring activity, competition, risk, and information. We investigate whether these variables explain the behavior of the OP and AI components of the spread over the trading day. We conclude that, on balance, the variables that determine the aggregate BAS also determine its intraday components.
