Although the effects of both news sentiment and expectations on price in financial markets have now been extensively demonstrated, the jointness that these predictors can have in their effects on price has not been well-defined. Investigating causal ordering in their effects on price can further our understanding of both direct and indirect effects in their relationship to market price.

We use autoregressive distributed lag (ARDL) methodology to examine the relationship between agent expectations and news sentiment in predicting price in a financial market. The ARDL estimation is supplemented by Grainger causality testing.

In the ARDL models we implement, measures of expectations and news sentiment and their lags were confirmed to be significantly related to market price in separate estimates. Our results further indicate that in models of relationships between these predictors, news sentiment is a significant predictor of agent expectations, but agent expectations are not significant predictors of news sentiment. Granger-causality estimates confirmed the causal inferences from ARDL results.

Taken together, the results extend our understanding of the dynamics of expectations and sentiment as exogenous information sources that relate to price in financial markets. They suggest that the extensively cited predictor of news sentiment can have both a direct effect on market price and an indirect effect on price through agent expectations.

Even traditional financial management firms now commonly track behavioral measures of expectations and market sentiment. More complete understanding of the relationship between these predictors of market price can further their representation in predictive models.

This article extends the frequently reported bivariate relationship of expectations and sentiment to market price to examine jointness in the relationship between these variables in predicting price. Inference from ARDL estimates is supported by Grainger-causality estimates.

This paper aims to answer the following important questions: Is public debt in Sub-Saharan African (SSA) countries sustainable? What are the determinants of public debt sustainability in these countries, and do these determinants exhibit heterogeneity due to regional, natural resource, and income differences among SSA countries?

This study analyzes the public debt sustainability in SSA countries using the theoretical model known as the Present Value Budget Constraint (PVBC) model developed by Hamilton and Flavin (1986), and adopts the econometric testing method proposed by Trehan and Walsh (1991). Moreover, to empirically investigate the determinants of public debt sustainability in SSA countries, the System-Generalized Method of Moments (System-GMM) method is applied. Furthermore, this study conducts heterogeneity analysis by categorizing the sample based on different regions, natural resource endowments, and income levels. The data of this study are sourced from the IMF and World Bank databases for 45 SSA countries from 2005 to 2021.

Findings reveal that public debt in SSA countries is not sustainable in the long run, with factors such as the previous government debt, long-term debt ratio, debt repayment capacity, economic growth rate, inflation rate, export to GDP, and government fiscal deficit rate influencing sustainability. Additionally, the factors exhibit heterogeneity attributed to regional, natural resource, and income variations among SSA countries.

The findings of our study will serve as a catalyst for policymakers in the SSA countries to embrace and sustain robust fiscal consolidation and debt stabilization measures. Moreover, countries with distinct characteristics should implement tailored approaches. Additionally, policymakers in SSA countries should implement economic measures to address public debt issues. These measures include improving the macroeconomic structure, promoting economic transformation and diversification of industries, fostering sustainable economic growth, ensuring price stability, and strengthening resilience against external shocks and debt risks. Specifically, countries endowed with indigenous species, resources, and tourism potential should adopt a well-coordinated strategy that utilizes agriculture, tourism, ecotourism, and the hospitality industry as instruments for sustainable local community and rural development.

Firstly, it assesses the sustainability of public debt and its determinants for countries in SSA, which distinguishes it from previous studies that only focus on either debt sustainability or determinants of debt separately. Secondly, by including multiple SSA countries in the analysis, this study stands out from prior research that predominantly concentrates on specific nations. Thirdly, the utilization of the System-GMM method for analyzing determinants adds a novel dimension to this study, departing from earlier literature primarily focused on debt thresholds. Lastly, the heterogeneity analysis conducted in this study provides an empirical foundation for tailoring policies to different countries, addressing a facet often overlooked in earlier literature.

This study aims to optimize the levels of factors for a green supply chain (GSC) while concurrently gaining valuable insights into the dynamic interrelationships among several factors, leading to reductions in CO₂ emissions and the maximization of the average service level, thereby enhancing overall supply chain performance.

Response surface methodology (RSM) is employed as a technique for multiple response optimization. This study uses a supply chain simulation model that includes decision variables related to the level of inventory control parameters and vehicle capacity. The desirability approach is adopted to achieve optimization objectives by focusing on minimizing CO₂ emissions and maximizing service levels while simultaneously determining the optimum levels of considered decision variables.

The high R² values of 97.38% for CO₂ and 97.28% for service level, along with adjusted R² values reasonably close to predicted values, affirm the models' capability to predict responses accurately. Key significant model terms for CO₂ encompassed reorder point, order up to quantity, vehicle capacity, and their interaction effects, while service level is notably influenced by reorder point, order up to quantity, and their interaction effects. The study successfully achieved a high level of desirability value of %99.1 and the validated performance levels confirmed that the results fall within the prediction interval.

This study introduces a metamodel framework designed to optimize various design parameters for a GSC combining discrete event simulation (DES) and RSM in the form of a simulation optimization model. In contrast to the literature, the current study offers an exhaustive and in-depth analysis of the structural elements of the supply chain, particularly the inventory control parameters and vehicle capacity, which are crucial for comprehending its performance and environmental impact.

This study investigates the optimum size for manufacturing firms and the impact of subcontracting on firms' likelihood of achieving their optimal scale in Vietnam.

Using data from the enterprise census in 2017 and 2021, the paper first estimates the production function to identify the optimum firm size for manufacturing firms and then, applies the logit model to investigate factors associated with the optimal firm size.

The study reveals that medium-sized firms exhibit the highest level of productivity. Nevertheless, a consistent trend emerges, indicating that nearly 90% of manufacturing firms in Vietnam operated below their optimal scale in both 2017 and 2021. An analysis of the impact of subcontracting on firms' likelihood to achieve their optimal scale emphasizes its crucial role, especially for foreign firms, exerting an influence nearly five times greater than that of the judiciary system.

The paper's findings offer crucial policy implications, suggesting that initiatives aimed at enhancing the overall productivity of the manufacturing sector should prioritise facilitating contract arrangements to encourage firms to reach their optimal size. These insights are also valuable for other countries with comparable firm size distributions.

This paper provides the first empirical evidence on the relationship between firm size and productivity as well as the role of subcontracting in firms' ability to reach their optimal scale in a country with a right-skewed distribution of firm sizes.

The link between entrepreneurial intention and positive attitudes towards entrepreneurship for established and nascent entrepreneurs has been well documented in the extant literature, with the theory of planned behaviour (TPB) viewing entrepreneurial intention as a pre-requisite for entrepreneurial pursuit. Whilst scholars generally agree on these insights, little empirical evidence exists on how marginalised social groups can convert their intentions into action. This study aims to understand to what extent the elements of TPB, the attitudes towards entrepreneurship, self-efficacy and subjective norms, help explain the emergence of entrepreneurial activity amongst marginalised demographic groups.

This research focuses on unemployed women residing in social housing located in a deprived urban area of the United Kingdom to empirically examine how multiple layers of disadvantage faced by this group shape their motivations and intentions for entrepreneurial pursuit. A multi-source qualitative methodology was adopted, drawing upon inductive storytelling narratives and extensive fieldwork on a sample of unemployed ethnic minority women residing in social housing in a deprived urban area of the United Kingdom. Community organisation representatives and housing association employees within the social housing system were included to assess the interpretive capacity of TPB.

The findings display that TPB illuminates why and how marginalised groups engage in entrepreneurship. Critically, women’s entrepreneurial intentions emerge as a result of their experiences of multiple layers of disadvantage, their positionality and the specificity of few resources they can activate from their disadvantageous position for entrepreneurial activity.

By illuminating the linkages between marginalised women’s positionality and their associated access to the limited pool of resources using the TPB lens, this study contributes to emerging works on disadvantaged populations and entrepreneurial intention-action debate. This work posits that despite facing significant additional challenges through their positionality and reduced ability to mobilise resources, women in social housing can defy the odds and develop ways to overcome limited capacity and structural disadvantage.

Working mothers experienced dramatic changes to their daily routines during the COVID-19 pandemic. Many began to work from home as they simultaneously tried to balance work demands with tending to their children. The purpose of the current study was to examine working mothers’ experiences during the pandemic.

In order to examine working mothers’ experiences of telework during the pandemic, we conducted a focus group study. 45 working mothers participated, and they answered questions about their experiences.

Three themes emerged from the focus groups: (1) motivation shifts amongst working mothers; (2) difficulty balancing roles as mother and employee; and (3) workplace expectations and support. Many mothers reported that their overall motivation as employees had decreased and that they experienced difficulty in fully attending to their work and their child(ren)’s needs. As mothers navigated the stress of working during the pandemic, they reported varying levels of workplace support and many credited working with other parents as a primary contributor to feeling supported.

The findings from the current study add to the growing body of literature documenting the dark side of teleworking for mothers who struggled immensely with work–life balance. This study builds on past research by allowing mothers to share their experiences in their own words and offering suggestions for how organizations can support mothers in navigating these ongoing challenges as teleworking continues to remain prevalent. The narratives collected hold important implications for practices and policies to best support the needs of mothers as they continue to work and care for their children within the home.
