In developing countries, local buyers often rely on relational contracting based on reciprocity and trust. This paper analyzes relational contracting and global value chain (GVC) governance by focusing on how domestic and foreign coffee exporters in Rwanda confront challenges.

Semi-structured interviews were conducted with 25 representatives of Rwandan private, Rwandan cooperative-owned and foreign exporters, and four coffee sector stakeholders.

Foreign firms export most Rwandan coffee, and local exporters express concerns about their ability to compete. Rwandan exporters face challenges accessing capital, competing with foreign firms and managing high transaction costs. They use relational contracts to reduce transaction costs, and they benefit from a monopsony zoning regulation that reduces competition. Foreign exporters face regulatory challenges: a government-set coffee price and the zoning regulation. They vertically integrate to reduce costs and lock in suppliers through prefinancing.

Future research should analyze differences between local and foreign exporters in other contexts to advance understanding of the different challenges faced and contracting approaches used.

Few GVC governance studies address the role of relational contracts in contexts where enforcement is costly. Considering relational contracts within GVCs can improve value chain analysis, specifically in the developing countries where many GVCs start.

This study aims to improve our understanding of side selling in farmer cooperatives. Cooperative member side selling, in which farmers divert produce from cooperatives to competitors, threatens coffee cooperatives. This is a problem in Burundi, where many households earn income from coffee and cooperatives serve a collective action function.

Using data from a survey of Burundian coffee farmers, we assess the determinants of two types of cooperative member side-selling behavior: selling to both cooperative and non-cooperative buyers and selling solely to non-cooperative buyers.

Farmers who sell to both cooperative and non-cooperative buyers are more likely to be male household heads, be more invested in coffee and have larger farms than non-side sellers, among other characteristics. Farmers who only sell to non-cooperative buyers are poorer and less invested in coffee than non-side sellers.

Additional research is needed to better understand why side-selling behavior differs between groups and to better understand how household head gender influences side selling. In addition, this study lacks qualitative data supporting quantitative findings. Future research should include qualitative methods to better understand motivations for side-selling behavior.

The study provides important information on what influences cooperative member side selling and focuses on specific types of side-selling behavior that have been largely overlooked. The study focuses on the role of household head gender in side selling, which is important, given the centrality of women to African agriculture.

Interest in car-sharing initiatives, as a tool for improving transport network efficiency in urban areas and on interurban links, has grown in recent years. They have often been proposed as a more cost effective alternative to other modal shift and congestion relief initiatives, such as public transport or highway improvement schemes; however, with little implementation in practice, practitioners have only limited evidence for assessing their likely impacts.

This study reports the findings of a Stated Preference (SP) study aimed at understanding the value that car drivers put on car sharing as opposed to single occupancy trips. Following an initial pilot period, 673 responses were received from a web-based survey conducted in June 2008 amongst a representative sample of car driving commuters in Scotland.

An important methodological aspect of this study was the need to account for differences in behaviour to identify those market segments with the greatest propensity to car share. To this end, we estimated a range of choice model forms and compared the ability of each to consistently identify individual behaviours. More specifically, this included a comparison of:

Standard market segmentation approaches based on multinomial logit with attribute coefficients estimated by reported characteristics (e.g. age, income, etc.);

A two-stage mixed logit approach involving the estimation of random parameters logit models followed by an examination of individual respondent's choices to arrive at estimates of their parameters, conditional on know distributions across the population (following Revelt & Train, 1999); and

A latent-class model involving the specification of C classes of respondent, each with their own coefficients, and assigning each individual a probability that they belongs to a given class based upon their observed choices, socioeconomic characteristics and their reported attitudes.

As hypothesised, there are significant variations in tastes and preferences across market segments, particularly for household car ownership, gender, age group, interest in car pooling, current journey time and sharing with a stranger (as opposed to family member/friend). Comparing the sensitivity of demand to a change from a single occupancy to a car-sharing trip, it can be seen that the latter imposes a ‘penalty’ equivalent to 29.85 IVT minutes using the mixed logit structure and 26.68 IVT minutes for the multinomial specification. Segmenting this latter value according to the number of cars owner per household results in ‘penalties’ equivalent to 46.51 and 26.42 IVT minutes for one and two plus car owning households respectively.

The purpose of this paper is to determine recidivism costs and benefits for 1,030 community-based male offenders enrolled in a domestic abuse program (DAP) compared to an untreated control group (n=1,030) matched on risk factors.

The study time frame was October 1, 2007-June 30, 2010 with reconvictions measured to December 31, 2010. Follow up averaged 19 months. Controls received standard community supervision, but no domestic violence group interventions. Follow up measures included court costs for violent and non-violent reconvictions; re-incarcerations and community-based orders costs measured in days.

Adjusting for time at risk, DAP enrollees had 29 percent fewer reconvictions, 46 percent fewer violent reconvictions, 34 percent fewer custodial days, but 23 percent more days on community orders. Costs: DAP enrollment avoided $2.52 M in custodial costs, but higher community correction costs (+$773 K) and court costs (+$5.8 K), reducing the DAP’s criminal justice system cost savings to $1.754 M ($8.92 M for the DAP group compared to $10.67M for controls). Cost benefits: when the 64 DAP program costs were deducted ($602 K), the net benefit to the New South Wales criminal justice system was $1,141 M, or $1,108 per enrollee, providing a net benefit/cost ratio of 2.89. If the DAP was completed, the net benefit was $1,820 per offender. These results compares favorably to economic evaluations of other community-based interventions.

Group interventions for domestically violent (DV) offenders can provide good investment returns to tax payers and government by reducing demand on scarce criminal justice system resources. The study provides insights into justice costs for DV offenders; a methodological template to determine cost benefits for offender programs and a contribution to cost-effective evidence-based crime reduction interventions.

Using a rigorous methodology, official court, custodial and community correction services costing data, this is the first Australian cost benefit analysis of a domestic violence group intervention, and the first to justify program expenditure by demonstrating substantial savings to the criminal justice system.

This study is among the very few to examine the firm's simultaneous use of both dimensions of open innovation and its influences on the firm's process innovation performance (PIP). Specifically, the authors consider the relationship between firm's external technology acquisition (ETA) and external technology exploitation (ETE) and examine their direct, indirect and mediating effect on the firm's PIP. The authors also examine the moderating effect of the organizations' unabsorbed slack (UASL) on the relationship between ETA and ETE.

Analyzing data collected from 311 small- and medium-sized software development firms in emerging market; Thailand, we show that both ETA and ETE have a positive effect on PIP and that ETE fully mediates the relationship between ETA and PIP.

The authors show that both ETA and ETE have a positive effect on PIP and that ETE fully mediates the relationship between ETA and PIP. Moreover, the relationship between ETA and ETE is positively moderated by the firms' unabsorbed slack (UASL) and that the influence of ETA on PIP through ETE is stronger under higher unabsorbed slack.

The authors extend the “traditional” performance outcome of outbound dimension of open innovation concept, which focuses exclusively on commercialization and market (Chesbrough, 2003b), by showing that ETE positively influences the firm's PIP. Moreover, the study explains the mechanism through which ETA influence the firm's PIP by proposing that ETE fully mediates the relationship between ETA and PIP.

The purpose of this paper is to explore the potential for developing a model for differentiating school shooters based on their characteristics (or risk factors) before the attack took place.

Data on 40 school shootings was compiled from the National School Safety Center’s Report on School Associated Violent Deaths and media accounts. Content analysis of the cases produced a set of 18 variables relating to offenders’ characteristics (or risk factors). Data were subjected to Smallest Space Analysis (SSA), a non-metric multidimensional scaling procedure.

Results revealed three distinct themes: Disturbed School Shooter, Rejected School Shooter and Criminal School Shooter. Further analysis identified links between these themes with the family background of the offender.

These findings have both significant theoretical implications in the understanding of school shooters and the crime in general. They offer potential for practical applications in terms of prevention and intervention strategies. A key limitation relates to the quality of data.

This is the first study to develop a model for differentiating school shooter characteristics.
