Could lean practices and process innovation enhance supply chain sustainability of small and medium‐sized enterprises?

Small and medium‐sized enterprises (SMEs) adopt lean practices (LP) to reduce waste across their organisational value chain, which helps achieve sustainability. Process innovation (PI) has also been applied through cleaner production, environmental management system, ecodesign, and so on to address both customers' needs and legislations by policymakers. Although prior studies reveal the effect of sustainable practices, LP, and PI on sustainable performance separately, less is known on the integrated effect of them on sustainability performance. Moreover, studies on mediating effect of LP and PI on sustainability performance are scant. This is significant as LP and PI are considered to be the enablers for achieving sustainability performance. This research addresses this knowledge gap. The research first theorises a model integrating these four major constructs (sustainability practices, LP, PI, and sustainability performance) through hypotheses development. Subsequently, using structural equation modelling, it is tested whether each of sustainability practices, LP, and PI effect sustainability performances. Additionally, mediating effect of LP and PI between sustainability practices and performances is derived. The study uses data from 119 SMEs within manufacturing industries in the Midlands, United Kingdom. Further, a few case studies have been undertaken to validate the findings from quantitative analysis. The overall results show that although sustainability practices, LP, and PI help achieve sustainability performance of SMEs supply chain through efficiency and responsiveness respectively, the mediating effect LP is more compared with PI. Moreover, SMEs adopt LP when they are economy focused and implement PI when they are pressurised by customers and/or policymakers.     

Team Production with Punishment Option: Insights from a Real‐Effort Experiment

This paper analyzes the consequences of allowing for punishment in a real‐effort pair production experiment. The behavior of the best performer in the team differs on whether he or she can impose a sanction on the less performing partner. When sanctions are not allowed, good performers reduce their effort in response to the advantageous difference in scores; when they can impose sanctions, their change in effort is no longer related to the difference in scores. To some extent, a sanction mechanism allows good performers to focus on their own performance. In the case of costless sanctions, not sanctioning a partner who under‐performs, what we refer to as forgiveness, prompts the latter to improve his or her performance, but applying the sanction has a stronger push effect.

The U.S.–Brazil relationship opportunity: Business synergies for a dynamic global environment

The U.S.–Brazil relationship features an intersection of public and private sectors characteristic of the post‐2000 dynamics of international business and governmental relations. As a triple helix reference for the private sector, the public sector, and academia, this article explores how further alignment of public and private interests of the United States and Brazil can improve the bilateral relationship between the two largest countries in the Western hemisphere. The first section recaps the U.S.–Brazil public relationship and cultural perspectives shared between Brazil and the United States. The second section reviews the relevance of the U.S.–Brazil relationship in Brazil's economy and business marketplace. Sections 3 through 5 discuss specific trade, investment, and tax agreements that can be mutually beneficial for the United States and Brazil. The final section recommends further areas for public–private cooperation between the United States and Brazil.     

Bank market power, economic growth and financial stability: Evidence from Asian banks

This paper examines whether Asian banks are still prone to moral hazard in the aftermath of the 1997 Asian crisis. Using a sample of commercial banks from 12 Asian countries during the 2001–2007 period, our empirical findings highlight that greater market power in the banking market results in higher instability. Although banks are better capitalized in less competitive markets their default risk remains higher. A deeper investigation however shows that such behaviour is dependent on the economic environment. Higher economic growth contributes to neutralize greater risk taking and higher instability in less competitive markets.     

Publish or teach? Analysis of the professor's optimal career path

This paper analyzes how faculty members dynamically allocate their efforts between improving their research and teaching skills, taking into account the organizational structures and incentives implemented by academic institutions. The model builds on the assumption that organizational structures have an impact on the nature of spillover effects between teaching and research competencies. We analyze the dynamic equilibrium under unilateral and bilateral spillovers, using the no-spillover case as a benchmark. The bilateral spillover case is the most appealing as it achieves the highest overall performance; however, the nature of the equilibrium and the career paths can be quite different depending on the parameters of the problem such as the obsolescence of competencies or the strength of the spillover effect. This finding provides interesting insights on what could be the most productive configuration of a higher education institution.     

From free oil to ‘freedom oil’: terrorism,war and US Geopolitics in the Persian Gulf

Oil has been a major driving force behind foreign interests, regional and domestic balance of power, and territorial conflicts in the Persian Gulf. As a result of the ‘9/11’ terrorist attacks debates on oil and the United States' security agenda have significantly shifted. If on one side, those opposing US military interventionism have argued that the ‘war on terror’ provided one more convenient cover for a renewed ‘imperialist oil grab’ in this region; on the other, links between oil and terrorism pointed at problems of governance in oil-producing countries. As the ‘war on terror’ became justified as a ‘war of liberation’ against oil-funded dictators, the US portrayed its foreign policy as shifting from ensuring free access to oil for the world market, to ensuring that oil is delivering ‘freedom’ to local populations. Although engaging the crucial issue of oil governance, there is yet little evidence given the number of war victims and potential vested interests that a US policy shift from ‘free oil’ to ‘freedom oil’ is genuine and viable.     

Analysis of ruin measures for the classical compound Poisson risk model with dependence

In this paper, we consider an extension to the classical compound Poisson risk model. Historically, it has been assumed that the claim amounts and claim inter-arrival times are independent. In this contribution, a dependence structure between the claim amount and the interclaim time is introduced through a Farlie–Gumbel–Morgenstern copula. In this framework, we derive the integro-differential equation and the Laplace transform (LT) of the Gerber–Shiu discounted penalty function. An explicit expression for the LT of the discounted value of a general function of the deficit at ruin is obtained for claim amounts having an exponential distribution.     

Race, ethnicity, and insurance as determinants of epidural use: analysis of a national sample survey

Despite widespread availability of pain interventions in childbirth, for most women, childbirth is associated with labor pain that exceeds expectations. Although epidural is superior to other medical interventions, the choice to use epidural still remains a matter of patient and doctor preference. Whether racial or ethnic characteristics influence preference of physician use or interact with insurance coverage is still unknown. This study used a large national sample of women to measure significant determinants of epidural use in order to discuss disparities in pain management. The findings suggest the need for nurse leaders to foster health policies that are sensitive to diversity and economics.
