The need for a strategic approach on the railways to the management of the vehicle–track interface

Network Rail's decision in 2003 to bring track maintenance back in-house was long-overdue recognition that responsibility for safety on Britain's railways cannot be abdicated – but there was more to it than that. The accidents at Hatfield and Potter's Bar (both in Hertfordshire, UK), in particular, had exposed very vividly how privatisation had encouraged each now separated and competing part of the industry to operate in its own interests: records, data and expertise were fragmented, and track and train operators alike each sought to minimise their individual costs in isolation. This paper argues from a systems analysis perspective that, on vehicle and track maintenance at least, the overall costs to the industry are in such circumstances likely to be higher than if the various parties were to work together towards minimising total track and train maintenance costs between them. Far from increasing efficiency, privatisation had the effect of reducing it.     

The impact of credit scoring on consumer lending

We study the adoption of automated credit scoring at a large auto finance company and the changes it enabled in lending practices. Credit scoring appears to have increased profits by roughly a thousand dollars per loan. We identify two distinct benefits of risk classification: the ability to screen high‐risk borrowers and the ability to target more generous loans to lower‐risk borrowers. We show that these had effects of similar magnitude. We also document that credit scoring compressed profitability across dealerships, and provide evidence consistent with the view that credit scoring may have substituted for varying qualities of local information.     

Rising top-income persistence in Australia: Evidence from income tax data

Using income tax administrative data for Australia, we examine levels and trends in the persistence in top-income group membership, focusing on the top 1 percent. Top-income persistence increased markedly between 1991 and 2018, with most of the increase occurring in the mid-2000s and early 2010s. In the mid- to late-2010s, Australian top-income persistence rates were near the top of the range of tax-data estimates for other countries. We decompose the increase into factors associated with (i) changes in the composition of the top-income group and (ii) increases in persistence rates for specific population subgroups. We find that the rise in top-income persistence is accounted for by changes in subgroup persistence rates, notably for individuals aged 35–64, and especially those aged 55–64. We suggest that these effects are partially related to increases in the effective retirement age over the relevant period.     

Global critical leadership: Educating global leaders with critical leadership competencies

Global critical leadership competency means espousing critical thinking skills in all aspects of leadership decision making in the global context. This paper reviews the actions of critical thinking, argues that global leaders too must lead critically, and draws attention to the deficiency of critical thinking curricula in higher education and subsequent lack of recent graduates with critical thinking competencies. Leading critically is defined as applying critical thinking skills to decisions about leadership actions in different situations and is a challenge for leaders, followers, and educators. Nevertheless, global leaders, stakeholders, and educators in global leadership programs must embrace this challenge in order to make informed decisions in global contexts.     

Growth and enduring epidemic diseases

This paper analyzes the interplay of human capital formation and economic growth when there is premature adult mortality. Failing adequate insurance arrangements, a long wave of such mortality can so undermine human capital formation as to induce an economic collapse. In nuclear family structures, random matching of partners is superior to assortative mating only if the shock is not too big and initial levels of human capital are not too low. Full pooling of mortality risks with equal treatment of all children in extended families may fend off a general collapse, depending on the initial conditions and the size and duration of the shock. To avoid undesirable effects on expectations, awareness campaigns should be complemented by policies that credibly promise to reduce future mortality. If mortality depends on the general level of human capital, indeterminacy can arise in the form of more than one rational expectations path.     

New development: All change? Performance assessment regimes in UK local government

Contrasting approaches to assessing the performance of public services highlight important issues for policy-makers and future research. We need systematic comparisons between countries. We should use a broader range of evidence. The public ought to have a greater role in designing performance criteria, and we need to know more about the impacts of assessments.     

Emerging Market Footholds and Knowledge: An Examination of New Product Launch Performance

As developed markets become more saturated, managers increasingly recognize the value of emerging markets as venues for growth opportunities. Yet, launching products into these markets is extremely risky due to weak institutional environments (e.g., lack of physical infrastructure), making success more uncertain. To alleviate this challenge, theory points to using emerging market footholds that yield market-specific knowledge. However, it is unclear whether knowledge is realized and, if so, what facets of harvested knowledge are effective in driving performance. Accordingly, we used data collected from a survey of business professionals to examine emerging market footholds and market-specific knowledge (i.e., customer, competitor, and logistics knowledge). Our results show that the extent of market presence held by an emerging market foothold is positively associated with all types of knowledge, yet only competitor and logistics knowledge—not customer knowledge—is positively associated with product launch performance. A supplemental sample of new product launches in developed markets revealed the opposite results wherein customer knowledge was the only significant predictor. Viewed collectively, the results suggest a market maturity threshold wherein logistics and competitive knowledge becomes less influential in driving performance, and customer knowledge becomes more influential.     

What is digital possession and how to study it: a conversation with Russell Belk,Rebecca Mardon,Giana M. Eckhardt,Varala Maraj,Will Odom,Massimo Airoldi,Alessandro Caliandro,Mike Molesworth and Alessandro Gandini

ABSTRACT

The platformisation of digital consumption, means that increasingly many of the things that we call ours – our messages, photos, music, achievements – are entangled in complex socio-technical arrangements which require ongoing market mediation. In this context, refining our understanding of what digital possessions are and how to study them is vital. This requires refocusing research away from existing comparative analyses between digital and material possessions. To do so, we organised an interdisciplinary roundtable discussion with critical marketers and digital media scholars, consumer researchers, digital sociologists and researchers in Human Computer Interaction (HCI) at the 11^th Interpretive Consumer Research Conference held in Lyon in May 2019. The result of that discussion is this curation of comments which deal with theoretical, methodological and critical issues and a bold agenda for future research.     

Earnings management,audit adjustments,and the financing of corporate acquisitions: Evidence from China

Acquirers are motivated to overstate earnings prior to stock-financed acquisitions. We hypothesize that audits help to detect and correct such overstatements. We test this using a difference-in-differences design, which compares audit adjustments to earnings for stock-financed and cash-financed acquirers before versus after the acquisitions. Consistent with our hypothesis, we find larger downward adjustments in the audits immediately before stock-financed acquisitions. Further analysis of regulatory sanctions suggests the downward adjustments are in fact warranted, rather than auditors being overly conservative. Moreover, modifications in audit reports suggest that downward adjustments do not correct all of the reporting irregularities in audited financial statements.
