‘Subjective well-being comprises of people's emotional responses, domain satisfactions, and global judgements of life satisfaction’ (Diener et al., 1999). The health-related Sustainable Development Goal (SDG-3) aims to ensure ‘good health and well-being’ for all, over the globe. The World Happiness Report (2022) reported a highly significant relation between the SDG-3 and the subjective well-being scores and hence for the improvement of citizen well-being suggested for a holistic approach to economic development. The present chapter examines the impact of global economic crisis 2008–09 on the subjective well-being using time series data for six selected countries for the time period 2004–2019. Considering the crisis as an ‘intervention’, this chapter performs interrupted time series analysis for single- and multiple-group (country) comparisons. The single group analysis finds that in the immediate year of crisis, there appeared to be significant decrease in subjective well-being, followed by a significant decrease in the annual trend subjective well-being relative to pre-crisis for most of the countries. In case of multiple group analysis, the regression results reveal that initial mean level difference between any country and remaining countries was significant for most of the countries. The difference in the subjective well-being trend between a particular country and remaining countries after initiation of the crisis compared to pre-crisis period has appeared to be significantly negative for all the countries considered in the analysis.

The primary focus of this study is to examine the distributional consequences of the widespread increase in prices. The fundamental question the study aims to address is whether the dynamics of income distribution due to higher inflation differ in the short term compared to the long run.

The authors estimated a panel-data model (fixed effects) using inequality and inflation data available at a high frequency, i.e. on a quarterly basis for over 30 years, and found evidence that inflation causes rapid swings in income distribution.

The authors’ contribution to the literature lies in providing evidence that inflation rapidly causes swings in income distribution, even after controlling for the state of the economy. The authors also demonstrate that the magnitude and direction of the effect of inflation on income inequality depend on whether the initial inflation rate is below or above the Federal Reserve’s target of 2%.

To the best of the authors’ knowledge, the authors are the first to emphasize that the targets set by central banks can drive the strength and direction of the relationship between inflation and income inequality.

The Organization for Economic Cooperation and Development (OECD) countries are facing unprecedented challenges related to climate change and population aging. The purpose of the analysis is to explore the relationship between population aging and environmental degradation, accounting for human capital, using a sample of 19 OECD countries over the period 1980–2019.

On the empirical methodology, the analysis uses panel estimators with heterogenous coefficients and an error structure that takes into consideration cross-country heterogeneity and cross-sectional dependence for a panel of 19 OECD countries over the period 1980–2019. To examine the relationship between population aging and environmental degradation, the authors employ two alternative measures of environmental degradation that is energy consumption and CO2 emissions in metric tons per capita. Concerning the regressors, the authors account for two alternative aging indicators, namely the elderly population and the old-age dependency ratios to confirm robustness.

The analysis provides evidence that population aging and human capital development (IHC) lead to lower energy consumption in the OECD sample. Overall, the growing number of elderly people in the OECD seems to act as a mitigating factor for energy consumption. The authors view these results as conveying the message that the evolution of population aging along with channeling government expenditures towards human capital enhancement are important drivers of curbing energy consumption and ensuring environmental sustainability. The authors' research is of great significance for environmental policymakers by illuminating the favorable energy consumption patterns that population aging brings to advanced economies.

The main limitation of this study concerns data availability. Future research, and subject to greater data availability in the future, could dig deeper into understanding the dynamics of this complex nexus by incorporating additional control variables. Similarly, the authors focus on aggregate renewable energy consumption, and the authors do not explicitly model the sources of renewable energy (wind, hydropower, solar power, solid biofuels and other). Additional analysis of the breakdown of renewable energy sources would be insightful – subject to data availability – especially for meeting the recently agreed new target of 42.5% for European Union (EU) countries by 2030. A deep transformation of the European energy system is needed for the EU to meet the target. Finally, extending the model to include a range of non-OECD countries that are also experiencing demographic transformations is a promising avenue for future research.

To the best of the authors' knowledge, this study is the first to examine the effects of population aging and human capital on environmental degradation using a broad set of OECD countries and advanced spectrum estimation methods. Given cross-sectional dependencies and cross-country heterogeneity, the authors' empirical results underline the importance of cross-OECD policy spillovers and knowledge diffusions across the OECD countries. The new “energy culture” calls for concerted policy action even in an aging era.

This study aims to examine whether social inclusion policies promote financial inclusion. Three social inclusion policies were analyzed: gender equality policies, environmental sustainability policies and social protection (SP) policies.

The study used the panel fixed effect regression methodology to analyze data from 48 low- and medium-income countries.

The results show that social inclusion policies do not have a significant effect on financial inclusion. Also, the older population is less likely to own an account at a formal financial institution in low- and medium-income countries that have strong environmental sustainability policies and institutions. The implication of the finding is that the policies and institutions established to promote environmental sustainability can discourage the older population from keeping the population's wealth in formal financial institutions in the country.

Policy makers should consider how social and environmental policies and programs can be designed to promote financial inclusion for older individuals in the individuals' countries.

The financial inclusion literature has not considered the role of social inclusion policies in promoting financial inclusion for individuals, businesses and the excluded groups in a country.

This article aims to study the nonlinear effect of financial inclusion on tax revenue of 21 low financial development countries (LFDCs) and 22 high financial development countries (HFDCs) from 2004 to 2020.

The study calculates the world average financial development index (FD̅) for all countries using data from the IMF. The average FD of HFDCs is higher than (FD̅). On the other hand, the average FD of LFDCs is lower than (FD̅). Data of 21 LFDCs and 22 HFDCs cover the period 2004–2020. With the small sample problem, we applied the Bayesian method to examine the nonlinear effect of financial inclusion on the tax revenue of the two groups of countries.

Using the Bayesian method, the results show that financial inclusion negatively impacts tax revenue with an absolute probability of 100% in LFDCs and a lower probability of 92.45% in HFDCs. Additionally, the financial inclusion threshold at LFDCs is 18.90. Below this threshold, financial inclusion promotes tax revenue with a 100% probability. On the contrary, when financial inclusion exceeds the threshold, it will have a negative effect on tax revenue. Similarly, the financial inclusion threshold at HFDCs is 20.14, with a probability of 92.45%.

To the best of the authors’ knowledge, this is the first paper to examine the nonlinear impact of financial inclusion on tax revenue in high and low financial development countries.

Lack of access to finance is a major constraint to the growth of small and medium-sized enterprises (SMEs) and entrepreneurship in developing countries. The recent proliferation of mobile phone services, access to the internet and emerging technologies has led to a surge in the use of FinTech in Africa and is transforming the financial sector. This paper aims to examine whether FinTech developments heterogeneously contribute to the growth of digital finance for SMEs and entrepreneurship in 47 African countries from 2013 to 2020.

The paper uses a novel method of moments quantile regression, which deals with heterogeneity and endogeneity in diverse conditions for asymmetric and nonlinear models.

The empirical results reveal that the rise of FinTech companies offering services in Africa heterogeneously increases digital finance for SMEs and entrepreneurship in their different stages of growth. FinTech developments have a strong and positive impact in countries with higher levels of digital finance than those with lower levels. FinTech developments and digital finance positively and significantly influence entrepreneurship in Africa, particularly in the nascent and transitional development stages of entrepreneurship. Institutional quality has a considerable positive moderating effect when used as a control rather than an interaction variable.

The results suggest the need to promote FinTech developments in Africa: to provide a wide range of alternative digital finance schemes to SMEs and to promote entrepreneurship, especially in countries where entrepreneurship is in the nascent and transitional development stages. The results also underscore the need to promote FinTech development through supportive regulations and institutional quality to reduce risks related to FinTech and digital financing schemes.

To the best of the authors’ knowledge, this paper is one of the first attempts to account for the often overlooked heterogeneity effects and show that the influence of FinTech developments is not homogenous across the varying development stages of digital finance and entrepreneurship.

This study aims to examine the diametrically opposite effects of probabilistic (risk) and nonprobabilistic uncertainty (ambiguity) on accounting conservatism.

This study uses panel regression models with year and industry-fixed effects. It uses financial and market data from the communication and energy sectors of 24 countries, encompassing 1,946 firms and 5,838 firm-year observations.

The study reveals that conservatism is a rational response to risk. However, in the presence of higher ambiguity where uncertainty exceeds firm control and outcomes become unpredictable, management reduces conservative accounting practices. Robustness tests support the validity of these findings across different institutional frameworks, agency risks, sample selection and heterogeneity.

This study contributes to the existing literature by exploring the contrasting effects of risk and ambiguity on accounting conservatism. It enhances the understanding of how various institutional factors influence the asymmetric recognition of bad news compared to good news under conditions of uncertainty.

By understanding the role of accounting conservatism in responding to uncertainties, regulators can develop more informed and effective policies that align with the dynamic nature of business environments.

This research provides novel and original ideas suggesting that the change in accounting conservatism is contingent upon the firms’ ambiguity or risk.

The purpose of this paper is to report on the use and content of written guidance produced by mental health services in England and Wales describing hospital leave for informally admitted patients.

Guidance on leave was requested from National Health Service (NHS) mental health trusts in England and health boards in Wales (n = 61) using a Freedom of Information submission. Data were analysed using content analysis.

In total, 32 organisations had a leave policy for informal patients. Policies varied considerably in content and quality. The content of policies was not supported by research evidence. Organisations appeared to have developed their policies by either adapting or copying the guidance on section 17 leave outlined in the Mental Health Act Codes of Practice for England and Wales (Department of Health, 2016; Welsh Government, 2016). Definitions of important terms, for example, leave and hospital premises, were either absent or poorly defined. Finally, some organisations appeared to be operating pseudo-legal coercive contracts to prevent informal patients from leaving hospital wards.

Research should be undertaken to explore the impact of local policies on the informal patient’s right to life and liberty.

All NHS organisations need to develop an evidence-based policy to facilitate the informal patient’s right to take leave. A set of national standards that organisations are required to comply with would help to standardise the content of leave policies.

To the best of the author’s knowledge, this is the first study to examine the use and content of local policies describing how informal patients can take leave from hospital.
