Linking green purchasing capabilities to environmental and economic performance: The moderating role of firm size

This study identifies firms’ green purchasing capabilities, classified into operational capabilities and dynamic capabilities, and measures their effects on the environmental and economic performance of a firm. We developed instruments to measure operational green purchasing capabilities and dynamic green purchasing capabilities. This study also investigates the moderating effect of firm size on the relationship between green purchasing capabilities and firm performance. The structural equation model (SEM) is used to analyse 239 responses from Japanese manufacturing companies. The results indicate that their green purchasing capabilities positively affect environmental and economic performance. Operational capabilities and dynamic capabilities have different levels of effects on green purchasing performance. A further analysis of the moderating effect of firm size shows that the high economic performance of green purchasing relies on the level of dynamic capabilities rather than firm size.     

Dynamic modelling of agroforestry and soil fertility interactions: implications for multi-disciplinary research policy

This paper attempts to contribute to one of the major aspects of international research agenda in agroforestry. A general framework is developed in this paper to capture the dynamic interactions of various components of agroforestry system. Using a multi-seasonal model of agroforestry, the competition among the system components in resource and input use and the trade-offs between different outputs of agroforestry system are analyzed. Policy implications for multi-disciplinary research are derived. It is argued that quantifying the potential benefits of agroforestry system requires reformulation of existing economic methods of analyzing agroforestry technology to contribute to the fuller understanding of the dynamic interactions among its various components.     

Why Are Mothers Working Longer Hours in Austria than in Germany? A Comparative Microsimulation Analysis*

Labour force participation rates of mothers in Austria and Germany are similar; however, full‐time employment rates are much higher among Austrian mothers. In order to find out to what extent these differences can be attributed to differences in the tax‐transfer system, we perform a comparative microsimulation exercise. After estimating structural labour supply models for both countries, we interchange two important institutional characteristics of the two countries ‐ namely, (i) the definition of the tax unit within the personal income tax and (ii) the parental leave benefit scheme. As our analysis shows, differences in mothers’employment patterns can partly be explained by the different tax systems: while Germany has a system of joint taxation with income splitting for married couples, Austria taxes everyone individually, which leads to lower marginal tax rates for secondary earners than in the German system.     

Subscription Mechanisms for Network Formation

We analyze a model of network formation where the costs of link formation are publicly known but individual benefits are not known to the social planner. The objective is to design a simple mechanism ensuring efficiency, budget balance, and equity. We propose two mechanisms towards this end; the first ensures efficiency and budget balance but not equity. The second mechanism corrects the asymmetry in payoffs through a two-stage variant of the first mechanism. Journal of Economic Literature Classification Numbers: C71, C72, D20.     

Managing information sharing and stewardship for public-sector collaboration: a management control approach

Information sharing is essential for public-sector collaboration but needs to be balanced with information stewardship obligations. There is little research on how public-sector managers can influence the attitudes and behaviours of their employees to achieve these competing objectives. To investigate this, the study applies a management control framework to a case study of a law enforcement organization attempting to improve its information sharing and stewardship. The study extends prior literature by providing insights into the specific effects that different management controls have for the information sharing and stewardship behaviours of employees involved in public-sector collaboration.     

Holliston Helping Hands

This case focuses on fraud investigation in a not‐for‐profit organization, along with an examination of governance and management control practices. The student assumes the role of an accountant investigating a possible fraud. The student is first presented with sample invoices paid by the organization that are fraught with irregularities and red flags of potential fraud. Drawing on the student's knowledge of control systems and corporate governance, the student's task is to identify suspicions of possible fraudulent transactions, identify key suspects, and develop an investigative plan. The class can also discuss recommendations to improve governance and control mechanisms to avoid future occurrences of fraud. The case is presented in three parts, and closely parallels a fraud investigation as additional information is revealed in each successive part of the case. This is much like peeling the layers of an onion which is a common way to describe the evolution of a fraud investigation. This case is based on a real fraud investigation conducted by one of the authors who was engaged by the province's Ministry of Health. Students who express disbelief about issues portrayed in the case can be reassured that these faithfully represent actual events.     

Mountain City Transit: Management Control and Performance Measurement

Mountain City Transit (MCT) is a short in‐class case based on a real‐life city transit department, a context with which students are very familiar. The case allows three delivery options for instructors. A first option is for instructors to use the case to introduce various elements of management control—the case is rich, thereby allowing students to identify multiple issues facing the organization. As a second option, instructors can use it as a performance management case wherein students build a balanced scorecard and receive a completed strategy map to analyze. As a third delivery option, the case can be used twice during the course, both to introduce management control and to discuss performance measurement. Students will also discuss real life implementation challenges that MCT and other organizations face.
