Machine learning is an increasingly key influence on the financial services industry. In this paper, we review the roles and impact of machine learning (ML) and artificial intelligence (AI) on the UK financial services industry. We survey the current AI/ML landscape in the UK. ML has had a considerable impact in the areas of fraud and compliance, credit scoring, financial distress prediction, robo-advising and algorithmic trading. We examine these applications using UK examples. We also review the importance of regulation and governance in ML applications to financial services. Finally, we assess the performance of ML during the Covid-19 pandemic and conclude with directions for future research.

The use of machine learning as an input into decision-making is on the rise, owing to its ability to uncover hidden patterns in large data and improve prediction accuracy. Questions have been raised, however, about the potential distributional impacts of these technologies, with one concern being that they may perpetuate or even amplify human biases from the past. Exploiting detailed credit file data for 800,000 UK borrowers, we simulate a switch from a traditional (logit) credit scoring model to ensemble machine-learning methods. We confirm that machine-learning models are more accurate overall. We also find that they do as well as the simpler traditional model on relevant fairness criteria, where these criteria pertain to overall accuracy and error rates for population subgroups defined along protected or sensitive lines (gender, race, health status, and deprivation). We do observe some differences in the way credit-scoring models perform for different subgroups, but these manifest under a traditional modelling approach and switching to machine learning neither exacerbates nor eliminates these issues. The paper discusses some of the mechanical and data factors that may contribute to statistical fairness issues in the context of credit scoring.

This article reviews the existing literature about management practices in family firms, the most prevalent form of corporate ownership around the world. I summarize the existing evidence that shows family firms are less likely to adopt structured management practices, especially ‘dynastic’ family firms that combine family ownership and control. I discuss what might be the unique features of family firms that drive the lower adoption of management practices, despite the evidence that improving management boosts their productivity and performance.

An enduring idea in economics and management sciences is that successful business strategies exploit complementarities across management practices within a firm. From this complementarity perspective, the success of business strategy requires utilizing a variety of interdependencies across management practices. Navigating large arrays of possible interdependencies implies that strategic decision-making is often conducted under high complexity and uncertainty. This paper provides an introduction to the conceptual foundations of complementarities in business strategy, and its implications for strategic decision-making and managerial learning. Against this backdrop, I outline issues of measurement and data collection for strategy practices, drawing on recent measurement efforts by academic researchers as well as national statistical agencies. The last part of the paper discusses how increased large-scale data collection on firm activity complementarities and strategy practices can inform a variety of policy areas, such as antitrust policy and merger review, industrial and innovation policy, tax policy, and public–private partnerships.

The empirical management literature has found that the education of both managers and the workforce more generally appears to be an important driver of better management practices. This article sets out how such relationships might be conceptualized, and suggests that in a complementarities framework, modern management practices can be thought of as a type of skill-biased technology. It then summarizes the literature that has explored the relationships between human capital and surveyed management practices in manufacturing firms and other sectors, highlighting the handful of papers that have found a positive correlation between management practices and measures of local skills supply. It concludes with a discussion of the policy implications that stem from what we know so far, together with avenues for future research that could shed more light on the causal mechanisms at play.

There is increasing interest in measuring management in schools. This paper discusses a popular measurement tool: the World Management Survey (WMS) for schools. Drawing on WMS data, secondary sources, and the recent literature on school management, we take stock of the WMS and make recommendations for its use in future research and policy. We conclude that the WMS remains a highly useful tool for its stated purpose—the standardized measurement of (a subset of) management practices within schools—and make two sets of recommendations. First, we encourage those seeking to benchmark management practices in schools to take a systems perspective by extending the WMS approach upwards into the education bureaucracy. Second, when measuring practices within schools, we recommend that researchers consider: how best to assess alignment across practices in the operations domain; the challenge of measuring student learning for monitoring and target-setting; and the context specificity of people management.

We review the literature on people management and performance in organizations across a range of disciplines, identifying aspects of management where there is clear evidence about what works as well as aspects where the evidence is mixed or does not yet exist. We organize our discussion by four lenses, or levels of analysis, through which people management can be viewed: (i) individual extrinsic, intrinsic, and psychological factors; (ii) organizational people management, operational management, and culture; (iii) team mechanisms, composition and structural features; and (iv) relationships, including networks, leadership, and individuals’ relationships to their job and tasks. Each of these four lenses corresponds not only to a body of literature but also to a set of management tools and approaches to improving public employees’ performance; articulating the connections across these perspectives is an essential frontier for research. We find that existing people management evidence and practice have overemphasized formal management tools and financial motivations at the expense of understanding how to leverage a broader range of motivations, build organizational culture, and use informal and relational management practices. We suggest that foregrounding the role of relationships in linking people and performance—relational public management—may prove a fertile and interdisciplinary frontier for research and practices.

In Europe, it is quite common for public opinions and national politicians to blame economic insecurity and rising inequality on deeper regional integration within the European Union (EU), and especially on the euro. There is, however, no empirical research that clearly identifies the euro as the cause of the recent increase in income inequality. Using the synthetic counterfactual methodology developed by Abadie and Gardeazabal (2003), I estimate what would have happened to inequality in both gross and net income within euro-area countries, had these countries not switched to the single currency. In most countries (especially peripheral countries), without the euro, gross-income inequality would have been lower, while net-income inequality would have been higher. These results imply that, while deeper economic integration might have exacerbated gross income inequality, lower interest rates allowed countries to counteract these disparities with their social welfare programmes.

This article charts the changing context of regional economic development and the advancement of both policy thinking and analysis on this issue. The shift away from ‘traditional’ regional policies, designed to bring about regional convergence, towards new approaches, designed to exploit the economic development potential of regions, is the focus of the article. Specific attention is paid to the emergence of regional development strategies in the process, where ‘regions’ may be defined functionally rather than administratively. We outline the elements of such strategies—including redefining objectives, new types of interventions, involvement of new actors, and the broadening and integration of regional interventions—which distinguish them from traditional policy and which will determine the degree of success achieved. In conclusion, the paper raises two points of interest, namely the need for more inclusive regional development processes and better implementation of these demanding strategies.
