Integrating sustainability and resilience in the supply chain: A systematic literature review and a research agenda

Sustainability has emerged as an important industrial strategic outlook expanding beyond organizational boundaries to include the supply chain. Simultaneously, the industry has also been faced with supply chain resilience concerns. Research on the intersection of supply chain sustainability and resilience is nascent and is a consequence of their observed mutual influences. However, confusion about concepts, implementation methods, and measurements of sustainable and resilient supply chains remains. This study completes a systematic literature review that critically examines several major observations and directions. We find the concept of sustainable supply chains is more established, and general agreement on its theoretical foundations exists. Supply chain resilience is relatively less mature. The nexus and relationships between the two topics are often incoherent: there is confusion on sustainable and resilient supply chains establishment; there is no clarity on what practices could jointly advance both areas. A major conflict exists since sustainability generally focuses on efficiency, while resilience seeks effectiveness. We recommend studies to analyze implementation relationships and impact. We also observe that performance measurement systems should be developed to assess supply chain sustainability and resilience performance taking with explicit consideration time horizons considered in these measures.     

A bioeconomic model for estimating the optimal level of deer and tag sales

This paper presents a dynamic model that determines the optimal number of deer hunting permit sales, subject to the objective of maximizing the discounted economic benefits stream from both the consumptive and nonconsumptive uses of deer. This bioeconomic model integrates economic benefits estimated using the dichotomous choice contingent valuation method with biological growth constraints on deer. Using a hunting zone in California as a case study, the model found that the optimal levels of buck hunting permits sold should change on a rotational basis over time and that the current practice of not selling doe hunting permits for that zone is non optimal.     

Auctions for PURPA purchases: A simulation study

Competition was introduced into the electric utility industry with the passage of the Public Utilities Regulatory Policy Act (PURPA) of 1978. Increasing interest has appeared in structuring the PURPA purchase market into an auction system. This paper addresses the design issues associated with setting up such markets and introduces a simulation model to study them. The simulation analysis is guided by theoretical issues such as the alleged inefficiency of first-price auctions. We find that efficiency concerns raised about first-price auctions turn out to be less important than simple theoretical concerns would suggest.     

Embodied and Disembodied Technical Change in Fisheries: An Analysis of the Sète Trawl Fishery, 1985–1999

Overfishing and excess capacity in mostfisheries around the world have generated considerableand increasing concern about their biological and economic performance ramifications. Theseproblems, in part, stem from substantialinvestment in technical improvements to boats andequipment in fishing fleets, which exacerbatesexcess fishing capacity and low returns tofishing effort and investment, given regulatoryand biological constraints. However, little attempt hasbeen made to quantify the extent or effects oftechnical change in fisheries. In this paper, we usedetailed data on innovation patterns for 19vessels in the Sète trawl fleet of southernFrance to evaluate the contributions oftechnical change to catch rates. We find thatembodied technical change enhanced productivity by approximately one percent per year between 1985 and 1999, but that external (disembodied) events counteractedthis trend, causing a net output decline ofabout three percent per year.     

Comparing the impact of management support on police officers’ perceptions of discretionary power and engagement: Australia,USA and Malta

Abstract

This paper uses Social Exchange Theory as a lens for comparing the impact of management support upon police perceptions of discretionary power and employee engagement, across three countries. A survey-based, self-report process collected data from 193 police officers in Australia, 588 from the USA, and 249 from Malta. Structural equation modelling was used to analyse the data. The findings suggest a significantly different management support context across the three countries, as well as significantly different perceptions of discretionary power. Across the three countries, police perceived relatively poor satisfaction with organizational management support and only some engagement levels. However, USA police perceived significantly more discretionary power than the other country samples. These findings provide greater clarity about the link between management support, discretionary power and engagement for the police officers. Since employee engagement likely affects policing outcomes, the findings suggest that poor management support of police officers could negatively affect the provided service. Potential strategies to enhance police engagement include (a) training police managers about how to manage so as to promote greater engagement, and (b) modifying police managers’ performance indicators in line with achieving better police engagement.     

Wage inequality, technology, and trade

The recent widening of wage inequality has been attributed by some to skill-biased-technical-change and by others to trade liberalization. This paper examines the two explanations within a unified model and also presents a new modeling of skill-biased-technical-change, where skilled workers replace unskilled ones. As a result technology adoption is endogenous and does not occur in all countries. Hence, wages for both types of workers, trade patterns and also factor productivities in all countries are endogenously determined. The model sheds light on the relationship between technology and trade, on the reasons for global productivity differences and on the causes for the recent rise in wage inequality.     

CEO compensation and the seasoned equity offering decision

Empirical research on seasoned equity offerings indicates that the decision to make an SEO typically engenders a decline in firm value, as investors interpret this decision as a signal of poor financial health or that the stock is overpriced. Here, we add to the literature by analyzing the short‐term market reaction to SEO announcements and the chief executive officer's link to firm performance (i.e. the proportion of CEO equity‐based compensation). Results support the hypothesis that investors are more likely to view the announcement of an SEO as a last resort source of capital when the proportion of CEO equity‐based compensation is high. In such cases of high equity‐based compensation, our findings indicate that the SEO announcement provides an incremental signal of financial distress above that provided by financial statements. We also find this relationship (last resort signal) to be stronger when large information asymmetries exist between management and investors. Thus, managers should consider the ramifications of executive compensation structure when considering whether to make an SEO. Copyright © 2006 John Wiley & Sons, Ltd.     

Ratings and confirmation

We present a formalism which makes explicit and precise the confirming effect of multiple observers and repeated trials on composite ratings, considering the relevant subjective inputs.     

Local public goods with mobility: Existence and optimality of a general equilibrium

The existence and optimality of a general equilibrium in a model with a finite number of locations among which the continuum of individuals (each individual belonging to one of a finite number of types) have to choose is investigated. Each community finances its own production of public goods by taxes. The way in which the tax burden in shared among the different types in the different regions is left arbitrary. The model allows for: restrictions on the mobility of either residents and/or workers, congestion and externalities in both production and consumption, commuting costs, preferences of an individual may also depend on his location as well as on the distribution of all individuals across locations.
