Volume and skewness in international equity markets

We examine the relation between trading volume and skewness in 11 international stock markets using daily and monthly data from January 1980 to August 2004. We construct single equation and VAR models of the relation between the first three moments of market returns and trading volumes. Our results show hitherto unrecognised channels of influence, and support the investor heterogeneity approach to explaining return asymmetries.     

Cultural influences on consumer satisfaction with impulse and planned purchase decisions

This study examines factors thought to influence consumers' planned and impulse purchase decisions including subjective culture (individualist or collectivist consumers) and the presence of another person at the time of purchase. Data was collected in four countries — the USA, Australia, Singapore, and Malaysia. The results indicate that overall, consumers are differentially influenced by others in planned and impulse purchase situations, even after controlling for price. These differential influences can be explained by culture. Compared to more individualist consumers, more collectivist consumers are likely to be more satisfied with an impulse purchase when another person is present at the time of purchase.     

From conflict to crisis in collaborative NPD

While manufacturer–supplier co-development of projects can contribute shared knowledge and expertise, such commitment also presents managerial challenges, particularly where crisis threatens the entire project. This paper explores how crisis is manifested, amplified, handled, and its outcomes in two longitudinal case studies, one between a food manufacturer and its packaging supplier and another between a window manufacturer and its software supplier. The analysis, the first to focus on co-development crisis, results in a better understanding of crisis episodes and in propositions around the crisis management challenges in co-developing new product projects.     

Temporal and spatial modelling of tropical deforestation: a survival analysis linking satellite and household survey data

We estimate a spatially explicit model of the forest clearance process among smallholder farmers in an agricultural frontier of southern Mexico. Our analysis takes as its point of departure a simple utility‐maximising model that suggests many possible determinants of deforestation in an economic environment characterised by missing or thin markets. Hypotheses from the model are tested on a data set that combines a time series of satellite imagery with data collected from a survey of farm households whose agricultural plots were geo‐referenced using a global positioning system (GPS). We implement a survival analysis to identify the effect of household level explanatory variables on the probability of deforestation. This approach allows us to introduce a measure of the time until clearance as a covariate, thereby affording a control for the effect of potentially important explanatory variables that vary through time but are not directly observable. In addition to identifying several variables relevant for policy analysis, including household demographics, proximity to roads, and government provision of agricultural support, model results suggest that the deforestation process is characterised by non‐linear duration dependence, with the probability of forest clearance first decreasing and then increasing with the passage of time.     

The Economics of Controlling Insect-Transmitted Plant Diseases

A framework is developed to analyze a spatially dependent economically significant pest problem emanating from a source and spreading via a carrier such as an insect. Transmission and/or source control to combat the pest or disease problem are explored. Alternative assumptions about the effectiveness of transmission control and the feasibility and costs, both social and private, of reduction of the pest population at the source are examined in an application of the model to controlling Pierce's disease in California wine grapes.     

Targeting and distribution in complex emergencies: Participatory management of humanitarian food assistance

The extensive literature on community participation in the targeting and management of humanitarian food assistance suggests that participatory approaches work best in slow-onset emergencies with no conflict or displacement. Yet the policies of many agencies—and compliance with Sphere minimum standards—require that the recipient community participate in decisions about the assistance they receive including targeting, regardless of the causes of the emergency. This paper analyzes current practice in the targeting and management of humanitarian food assistance in complex emergencies, the constraints to recipient communities’ participation, and the possibilities for participatory approaches to improve targeting.     

Strategic market environments

The marketing strategy literature stresses the need to find an optimum “fit” between the firm and its environment. Utilising a relatively novel clustering technique, five distinct environments facing marketing managers in the United Kingdom were identified and the marketing strategies adopted in each environment examined. Marketing objectives and strategic focii were found to differ markedly by strategic environments, while competitive advantages created and pursued did not. The latter were found to be company, rather than environment, specific.
