Abstract
Purpose
The purpose of this paper is to propose and demonstrate a new additive manufacturing approach that breaks the layer-based point scanning limitations to increase fabrication speed, obtain better surface finish, achieve material flexibility and reduce equipment costs.
Design/methodology/approach
The freeform additive manufacturing approach conceptually views a 3D article as an assembly of freeform elements distributed spatially following a flexible 3D assembly structure, which conforms to the surface of the article and physically builds the article by sequentially forming the freeform elements by a vari-directional vari-dimensional capable material deposition mechanism. Vari-directional building along tangential directions of part surface gives surface smoothness. Vari-dimensional deposition maximizes material output to increase build rate wherever allowed and minimizes deposition sizes for resolution whenever needed.
Findings
Process steps based on geometric and data processing considerations were described. Dispensing and forming of basic vari-directional and vari-dimensional freeform elements and basic operations of joining them were developed using thermoplastics. Forming of 3D articles at build rates of 2-5 times the fused deposition modeling (FDM) rate was demonstrated and improvement over ten times was shown to be feasible. FDM compatible operations using 0.7 mm wire depositions from a variable exit-dispensing unit were demonstrated. Preliminary tests of a surface finishing process showed a result of 0.8-1.9 um Ra. Initial results of dispensing wax, tin alloy and steel were also shown.
Originality/value
This is the first time that both vari-directional and vari-dimensional material depositions are combined in a new freeform building method, which has potential impact on the FDM and other additive manufacturing methods.

Abstract
Purpose
This paper provides a systematic review of literature pertaining to the welfare impact of financial inclusion. We identify the 50 most influential publications in the field that have evolved into three distinct categories, each of which we critically review to identify the main contributions of this research area.
Design/methodology/approach
By conducting a state-of-the-art literature review, this paper identifies the most influential papers in the research fields on the welfare impact of financial inclusion. One caveat is that as newer publications generally have fewer citations, reviewing prior work can result in a misleading account of emerging trends and research directions. Manual assessment of publications after 2018 facilitates a discussion of important emerging research trends and their directions.
Findings
The three key research streams are identified as financial services and financial accessibility, financial capability, and financial literacy and household welfare. By assessing publications from 2018 to 2023, we also document four key emerging research trends: Fintech and digital financial inclusion, sustainability and climate change, growth, poverty, income inequality, financial stability, and Entrepreneurship. Drawing on these emerging trends, we highlight the opportunities for future research.
Research limitations/implications
Keyword searches have limitations as some papers might be overlooked if they do not match the specific search criteria, despite their relation and significance to the overall topic of the welfare impact of financial inclusion. To address this issue, we have expanded this review by incorporating more literature from other databases, such as the Scopus database which may alleviate this issue.
Practical implications
The three key research streams contribute to a comprehensive understanding of the welfare impact of financial inclusion. The emerging trends integrate existing knowledge and leave the chance for innovative research to expand the research frontier.
Originality/value
This paper fulfils the systematic literature review streams in the welfare impact of financial inclusion and provides fruitful opportunities for future research.

Abstract
Purpose
This study aims to systematically review the literature in the fields of liquidity, informational efficiency and default risk. The authors outline the key research streams and provide possible pathways for future research.
Design/methodology/approach
The study adopts bibliographic mapping to identify the most influential studies in the research fields of liquidity, informational efficiency and default risk from 1984 to 2021.
Findings
The study identifies four key research themes that include efficiency and transparency of markets; corporate yield spreads; market interactions: bonds, stocks and cryptocurrencies; and corporate governance. By assessing publications published from 2018 to 2021, the authors also document seven key emerging research trends: cross markets, managerial learning and corporate governance, state ownership and government subsidies, international evidence, machine learning (FinTech approaches), environmental themes and financial crisis. Drawing on these emerging trends, the authors highlight the opportunities for future research.
Research limitations/implications
Keyword searches have limitations since some studies might be overlooked if they do not match the specified search criteria, even though their relevance to the topic is under investigation. Adopt the R project to expand this review by incorporating more literature from other databases, such as the Scopus database could be a possible solution.
Practical implications
The four key research streams contribute to a comprehensive understanding of liquidity, informational efficiency and default risk. The emerging trends integrate existing knowledge and leave the chance for innovative research to expand the research frontier.
Originality/value
This study fulfills the systematic literature review streams in the fields of liquidity, informational efficiency and default risk, and provides fruitful opportunities for future research.

Abstract
Purpose
This study investigates how finance contributes to socioeconomic development through an inclusive financial system and the impact of financial inclusion programs pursued by non-bank financial institutions (NBFIs) in Ghana.
Design/methodology/approach
In this study, we leverage a rich, nationally representative household survey (ICPSR, 2014) from 17 Ghanaian MFIs (1,629 households), sponsored by the World Bank, to analyze microfinance impacts using a generalized method of moment (GMM) and channel analysis.
Findings
Our findings reveal a statistically significant positive impact of donor-funded financial inclusion projects on targeted households’ welfare, regardless of implementing agency (donor, government or microfinance institution). The channel analysis further suggests that credit unions and savings and loan (S&L) institutions may be particularly effective conduits for delivering these welfare gains through financial inclusion programs. These findings hold valuable insights for funders seeking to maximize the welfare impact of such interventions: credit unions and S&Ls may be preferential channels for delivering financial inclusion programs aimed at improving household well-being.
Research limitations/implications
The poverty-reducing impact of informal non-bank financial intermediaries like credit unions and susu groups highlights the need for policies that integrate these institutions into the formal financial system. Therefore, donor-funded initiatives should not rely solely on local government implementation. Since the focus of this study is on Ghana, we caution readers to exercise caution when generalizing the findings to other jurisdictions.
Practical implications
The World Bank/IMF-backed financial sector reform in Ghana has many important implications for financial inclusion and welfare impacts which are rare in other jurisdictions. Our finding has policy implications for agencies that wish to translate financial inclusion into significant economic inclusion, especially in middle- and low-income countries (LICs) where the COVID-19 pandemic and the global impact of the recent war in Ukraine could exacerbate the exclusion gap.
Originality/value
The focus of this study is to understand if MFIs, funded by different sources, can contribute to inclusive growth and welfare. This research employs channel analysis, considering that donor and government programs are often channeled through community-based NBFIs and offer key contributions to the existing body of knowledge on financial inclusion and household welfare. This study extends the current literature by providing a deeper understanding of the role of each NBFI type in deepening financial inclusion and improving household welfare and allows policymakers, donors and governments to target inclusion efforts for maximum impact.

Abstract
Purpose
This study examines the influence of CEO characteristics on firm innovation within the Australian market, using R&D expenditure as a proxy for innovation. The aim is to analyze how factors such as CEO gender, educational background and dual roles (CEO-chairman) impact firms' R&D investment across various industries.
Design/methodology/approach
Panel and Tobit regression models are employed to assess the relationship between CEO characteristics and R&D expenditure. The study controls for endogeneity and applies firm-level control variables to ensure robustness, examining CEO traits like gender, educational qualifications and CEO-chairman duality.
Findings
The study reveals that CEO gender and educational level significantly impact firm innovation, particularly R&D expenditure, compared to other characteristics like CEO-chairman duality. Female CEOs and those with PhD degrees are associated with higher R&D spending, with variations across industries such as basic materials and healthcare.
Research limitations/implications
The study is limited by its focus on Australian firms and the time span of 2006–2016. Additionally, mixed results for CEO-chairman duality and CEO location may reduce the generalizability of the findings across all industries on the ASX.
Practical implications
The findings highlight the importance of gender diversity and CEO education in driving firm innovation. Companies aiming to enhance competitiveness and performance through R&D activities, especially in industry-specific contexts, should consider these CEO characteristics.
Originality/value
This study provides novel insights by analyzing the impact of CEO characteristics, such as gender and education level, on firm innovation in the underexplored Australian market. By using R&D expenditure as a proxy for innovation and employing both panel and Tobit regression models, it highlights the significance of CEO traits, particularly in specific industries. The findings emphasize the stronger influence of CEO gender and educational level compared to CEO-chairman duality and location, offering valuable implications for gender diversity and industry-specific innovation strategies in enhancing firm competitiveness.

Abstract
Purpose
This study sheds new light on the personality trait and provides evidence regarding the relation between narcissism and desirable accounting practices, specifically the impact of CEO narcissism on accounting conservatism.
Design/methodology/approach
The authors test the relation between CEO narcissism and accounting conservatism for a sample of 907 US companies and their corresponding CEOs for the period between 2010 and 2018. The authors apply three established models of accounting conservatism and measure executives' narcissism using a non-intrusive approach ubiquitous in the literature.
Findings
The authors find that CEO narcissism is associated with speculative accounting practices in the form of timely recognition of positive news and more prudent financial reporting of anticipated negative news. The authors provide the first empirical evidence that, despite its well-known negative effects on corporate financial reporting, executive narcissism can also produce positive outcomes.
Originality/value
While managerial overconfidence has received much attention, the effects of executives' narcissism are still widely unexplored (Chatterjee and Hambrick, 2007). The authors thus contribute to the literature by investigating the relationship between CEOs' narcissism and accounting conservatism. The authors conjecture CEO narcissism should have a twofold effect on prudent financial reporting. On the one hand, CEOs' narcissism should be associated with low levels of unconditional conservatism due to excessively fast good news recognition. On the other hand, narcissistic executives should be associated with early recognition of negative news and hence with higher levels of conditional conservatism.

Abstract
This paper examines the relationship between transportation quality, customer satisfaction and profitability. Specifically, this study examines the simultaneous and asynchronous effect of quality of transportation services on customer satisfaction and financial performance and then performs the same examination in relation to the effect of customer satisfaction on financial performance. The partial least squares approach to structural equation modelling is used to examine longitudinal data from 1995 to 2018 from the US airline industry. The findings suggest that low service quality in transportation has adverse effects on customer satisfaction and financial performance, while the impact of customer satisfaction on financial performance in the US Airline transportation industry is mixed. The authors found that the impact of customer satisfaction on financial performance is significant in full-service airlines but not in low-cost airlines. Surprisingly, the authors found no significant direct relationship between transportation quality and financial performance in the US airline industry.
