Abstract

Purpose

This paper examines the impact of forward guidance in monetary policy on the pass-through of interest rates in New Zealand by analyzing the degree of both the long-term and short-term pass-through.

Design/methodology/approach

We use dynamic OLS to estimate the long-term relationship between the official cash rate and the time-deposit rates and various lending rates of New Zealand banks. We use a standard error correction model to estimate the short-term dynamics.

Findings

The results show that implementing forward guidance improves the degree of long-term pass-through, especially for time-deposit interest rates and longer-term fixed mortgage rates. Furthermore, the markup for various lending rates decreased, and the degree of short-term pass-through increased slightly after the implementation.

Practical implications

Implementing forward guidance enhances the transmission of monetary policy. Commercial banks are able to respond more quickly to changes in monetary policy by adjusting their deposit and loan rates.

Originality/value

New Zealand is the first country to mandate inflation targeting. Since its birth in 1990, the 2% inflation target has become the norm for central banks all over the world, including the FED, European Central Bank, Bank of Japan, Bank of England, etc. To our knowledge, ours is the first paper to examine the impact of forward guidance on the interest rate pass-through.

Abstract

Purpose

Vision transformers (ViT) detectors excel in processing natural images. However, when processing remote sensing images (RSIs), ViT methods generally exhibit inferior accuracy compared to approaches based on convolutional neural networks (CNNs). Recently, researchers have proposed various structural optimization strategies to enhance the performance of ViT detectors, but the progress has been insignificant. We contend that the frequent scarcity of RSI samples is the primary cause of this problem, and model modifications alone cannot solve it.

Design/methodology/approach

To address this, we introduce a faster RCNN-based approach, termed QAGA-Net, which significantly enhances the performance of ViT detectors in RSI recognition. Initially, we propose a novel quantitative augmentation learning (QAL) strategy to address the sparse data distribution in RSIs. This strategy is integrated as the QAL module, a plug-and-play component active exclusively during the model’s training phase. Subsequently, we enhanced the feature pyramid network (FPN) by introducing two efficient modules: a global attention (GA) module to model long-range feature dependencies and enhance multi-scale information fusion, and an efficient pooling (EP) module to optimize the model’s capability to understand both high and low frequency information. Importantly, QAGA-Net has a compact model size and achieves a balance between computational efficiency and accuracy.

Findings

We verified the performance of QAGA-Net by using two different efficient ViT models as the detector’s backbone. Extensive experiments on the NWPU-10 and DIOR20 datasets demonstrate that QAGA-Net achieves superior accuracy compared to 23 other ViT or CNN methods in the literature. Specifically, QAGA-Net shows an increase in mAP by 2.1% or 2.6% on the challenging DIOR20 dataset when compared to the top-ranked CNN or ViT detectors, respectively.

Originality/value

This paper highlights the impact of sparse data distribution on ViT detection performance. To address this, we introduce a fundamentally data-driven approach: the QAL module. Additionally, we introduced two efficient modules to enhance the performance of FPN. More importantly, our strategy has the potential to collaborate with other ViT detectors, as the proposed method does not require any structural modifications to the ViT backbone.

Abstract

Purpose

This paper aims to solve the problem that multiscale dispersion entropy (MDE) is prone to information loss in the process of coarse-grain, which makes it difficult to extract bearing fault information comprehensively.

Design/methodology/approach

A new fault diagnosis method of rolling bearing using refined composite multiscale peak-to-peak normalized dispersion entropy (RCMPNDE) and sparrow search algorithm optimized probabilistic neural network (SSA-PNN) is proposed. First, coarse-graining employs the peak-to-peak value calculation instead of the segmented mean calculation in the RCMDE algorithm, which can overcome the shortcomings of traditional coarse-graining and highlight the fault characteristics. Then, the influence of the selection of different parameters is reduced through the normalization operation, and the RCMPNDE is formed. Finally, the extracted feature parameters are combined with SSA-PNN for diagnosis recognition to construct the RCMPNDE-SSA-PNN fault diagnosis method.

Findings

The proposed RCMPNDE-SSA-PNN fault diagnosis method is tested on actual data sets and its outcomes have been compared to those generated by methods built upon MDE, RCMDE and PNN. The comparison results showed that the proposed method can extract the fault feature information of rolling bearings more accurately and improve the accuracy of fault classification. The recognition accuracy reached 98.5% under the conditions of this experiment.

Originality/value

The RCMPNDE-SSA-PNN method can obtain more accurate fault diagnosis accuracy and provide a new reliable diagnosis method for rolling bearing fault diagnosis.

Abstract

Purpose

In the practice of live streaming e-commerce, the consumer demand is usually uncertain, and the inventory and prices can be decided by brand owners or streamers. To this end, this study examines the inventory and pricing decisions of the brand owner and streamer in a live streaming e-commerce supply chain under demand uncertainty.

Design/methodology/approach

In this study, four scenarios are considered, i.e. the brand owner determines the inventory and price (Scenario BB), the brand owner determines the inventory and the streamer determines the price (Scenario BS), the streamer determines the inventory and the brand owner determines the price (Scenario SB), and the streamer determines the inventory and price (Scenario SS).

Findings

The results show that the inventory and prices, as well as the profits of the brand owner and streamer increase with the consumer sensitivity to streamer’s sales effort level under the four scenarios. The inventory (price) is the highest under Scenario SS (SB), while that is the lowest under Scenario BB (BS). In addition, when the sensitivity is low, the brand owner’s profit is the highest under Scenario BB, otherwise, the profit is the highest under Scenario SS. Regardless of the sensitivity, the streamer’s profit is always the highest under Scenario SS.

Originality/value

Few studies focused on the inventory and pricing decisions of brand owners and streamers in live streaming e-commerce supply chains under demand uncertainty, while this work bridges the research gap. This study can provide theoretical basis and decision support for brand owners and streamers.

Abstract

Purpose

To deepen the structural reform of the financial system on the supply side and mitigate associated risks in the economic and financial fields, with significant practical implications for FinTech development.

Design/methodology/approach

Based on microdata of listed companies, this paper constructs multi-level indicators of FinTech development. Robustness tests include alternative measures of the degree of long-term use of short-term debts, sample adjustments and heterogeneity in firm characteristics and regional differences.

Findings

FinTech can significantly alleviate the long-term use of short-term corporate debt, although there are heterogeneous effects. The alleviation effect is more pronounced for state-owned enterprises, non-technology-intensive enterprises and other companies with lower levels of short-term debt maturity. Additionally, in regions with high capital mismatch and high levels of financial development, FinTech exhibits a significant suppressive effect on the long-term use of short-term corporate debt.

Practical implications

The paper suggests promoting the diversification of FinTech products, emphasizing the importance of inclusive finance through FinTech, and driving China’s economic transformation and high-quality development.

Originality/value

By constructing a theoretical analysis framework of “FinTech—corporate investment and financing term mismatch,” this paper provides a multi-level estimation of the factors influencing FinTech’s impact on the long-term use of short-term corporate debt. This framework aids in developing a more dialectical and objective understanding of the economic effects of FinTech’s development.

Abstract

Purpose

The high-load operation of the engine crankshaft causes severe wear and fatigue. This study aims to prepare in situ textures with effective density and study their wear mechanism on the surface of ductile cast iron, which optimizes the tribological properties of engine crankshafts and reduces wear.

Design/methodology/approach

A new method was proposed based on the hardness difference in graphite removal to form an in situ texture. The friction performance was evaluated using a combination of computational fluid dynamics and tribological testings. The influence of the texture characteristic parameters on the bearing capacity of the oil film was analyzed. The surface wear morphology was studied by scanning electron microscopy.

Findings

The texture density significantly affected the oil film bearing capacity. The surface texture can reduce the average friction coefficient (COF) by more than 35% owing to the oil film bearing and storage capacity. Specifically, the 13% texture density exhibited the lowest wear rate and COF under all three experimental conditions. The reduction in abrasive particles in the wear area of the textured surface indicates that the surface texture can improve the lubrication mechanism.

Originality/value

This study systematically explored the influence of the weight of each model parameter on tribological properties. Subsequently, focusing on the critical parameter (texture density), detailed tribological testings were carried out to reveal the specific effect of texture density on the wear mechanism under different working conditions, and the optimal texture density to achieve the optimal tribological performance was determined accordingly.

Abstract

Purpose

The article focuses on cross-sectoral analysis concerning services, especially ICT services, flowing from China to European manufacturing. The aim of the study is to analyse Sino-European relations in terms of ICT servicification. The article attempts to answer the following questions: does China’s relationship with Europe in terms of the servicification of manufacturing align with global servicification trends? Have global economic shocks, such as decoupling policies, diminished the flows of Chinese ICT services in European advanced manufacturing sectors?

Design/methodology/approach

This study employed input–output models to analyse the increasing role of China as a supplier of ICT services to European manufacturing. It also identified the industries that are most dependent on Chinese ICT services.

Findings

The analysis highlights the increasing reliance of European manufacturing on Chinese ICT services, with a notable rise across both Western Europe and CEE. This dependency is particularly strong in advanced sectors such as automotive and electronics, and there is no evidence of decoupling from China, even amidst global shocks or geopolitical tensions like the Trump presidency. Additionally, the BRI had limited direct impact, as the servicification trends appear driven more by broader globalization processes.

Originality/value

The study investigates all European countries and their manufacturing sectors’ reliance on Chinese services. It concentrates on services related to high technology, specifically ICT. Moreover, the previous research has focused on servicification of manufacturing, in general, neglecting industry-specific analysis. It contributes to the literature by providing insights into the relationships between developing and developed economies in terms of GVCs in the context of digital servicification and decoupling conditions.

Abstract

This research paper examines the complex interplay of trust, corruption, and governance during the COVID-19 pandemic, analysing how these sociopolitical factors influence public health outcomes. Utilising the Generalised Additive Model (GAM) for Corruption Risk and Trust, the study provides a fresh perspective on the pandemic’s multifaceted impact, extending beyond traditional biomedical approaches. Through an in-depth analysis of global data, the paper unveils the intricate links between public confidence in government and the perceived integrity of political systems, highlighting how these elements affect the pandemic’s fatality rates. It also sheds light on the role of misinformation and politicisation in moulding public perceptions and responses to the crisis. This work offers a crucial viewpoint for understanding the ongoing challenges posed by COVID-19, emphasising the critical need for transparent and reliable governance in managing public health emergencies. The findings underscore the significant influence of governance quality, societal trust, and corruption on health crises. Contributing to the broader discussion on the interaction between political, social, and health factors during emergencies, this study has important implications for policymakers, health professionals, and the international community.

Abstract

Purpose

The process of conveyance of solid–liquid mixtures poses a significant challenge due to the considerable wear and tear experienced by critical components. This issue not only affects the lifespan of the system but also jeopardizes its safe operation. The purpose of this study is to numerically and experimentally investigate the erosion wear behavior of impeller steels (SS-410 and S-317) using Computational Fluid Dynamics (CFD) and Design of Experiments (DOE) techniques, aiming to address the significant challenges posed by wear in slurry transportation systems.

Design/methodology/approach

In this study, a robust two-phase solid-liquid model combining CFD with Discrete Phase Modeling (DPM) was applied to simulate the effects of coal-ash slurries on impeller steel. Additionally, an experimental evaluation was conducted using the DOE approach to analyze the impact of various parameters on impeller steel. This integrated methodology enabled a comprehensive analysis of erosion wear behavior and the influence of multiple factors on impeller durability by leveraging CFD for fluid flow dynamics and DPM to model particle interactions with the steel surface.

Findings

Simulation results highlight a strong link between particle size and the wear life of impeller steel. Through simulations and experiments on SS-410 and SS-317 under varied conditions, it’s evident that SS-410 outperforms SS-317 due to its higher hardness and density. This is supported by Taguchi’s method, with SS-410 showing a higher Signal-to-Noise ratio. Notably, particle size emerges as the most influential parameter compared to others.

Originality/value

Current research primarily focuses on either CFD or experimentation to predict pump impeller steel erosion wear, lacking relevant erosion mechanism insights and experimental data. This study bridges this gap by employing both CFD and DPM methods to comprehensively investigate particle effects on pump impeller steel and elucidate erosion mechanisms.

Abstract

This study aims to investigate the impact of client size, client risk, client profitability, client complexity, audit reporting lag, client loss, audit firm size, and industry type on determining external auditor fees pre- and during the COVID-19 pandemic on the non-financial companies (53 industrial companies and 41 service companies) listed at the Amman Stock Exchange (ASE) for the period of 2017–2021. The initial number of observations started with 470 observations. The results of the regression analysis for the pooled sample revealed a significant positive impact for the factors of client size, client complexity, and audit firm size on external audit fees. The same results were found for the other two sub-samples. However, client loss and industry type indicated a significant negative impact on external audit fees, except for the pre-COVID-19 pandemic period for the loss and the COVID-19 pandemic period for the audit firm size. Moreover, client risk, audit report lag, and client profitability have an insignificant impact on external audit fees for all three samples. Furthermore, the study recommends the following: Allocate adequate resources for auditing and consider the influence of company size on audit fees, adjust audit budgets based on profitability and the potential complexity of financial statements, and analyze and communicate the level of complexity to auditors, especially for companies operating in multiple industries or with intricate structures.
