The impact of tax burden on welfare attitudes: Micro evidence from welfare states

The attitudes of the general public with regard to social welfare are of crucial importance in determining the efficacy and stability of a nation’s welfare system. The manner in which taxation is employed as a means of funding mechanism for welfare policies is of great consequence. Nevertheless, existing research on the subject of welfare attitudes has largely neglected the tax perspective, underscoring the need for investigations that bridge this gap and provide a more comprehensive understanding of the intertwined dynamics between taxation and public perception of social benefits. This study investigates the influence of tax burdens on attitudes towards welfare using an ordered probit model applied to data from the 2019 International Social Survey Program (ISSP 2019 Social Inequality V), encompassing 11 welfare states. Our key findings are as follows: (1) Empirical analysis reveals that a moderate tax burden correlates with a reduction in public expectations regarding governmental responsibility for welfare provision. (2) Heterogeneity analysis elucidates a negative association between tax burdens and welfare attitudes across diverse welfare regimes. (3) The mediating effect test suggests that perceptions of social fairness partially mediate the relationship between tax burdens and welfare attitudes. (4) The moderating effect test indicates that government efficacy negatively moderates the impact of tax burden on welfare attitudes. This study offers insightful perspectives for policymakers aiming to design and implement tax systems that align effectively with societal structures.

Willingness to pay of Portuguese sparkling wine consumers: Econometric and machine learning approaches

Abstract Understanding consumer choices and their drivers of willingness to pay (WTP) for a bottle of wine has been a research challenge in wine economics, particularly in niche markets such as sparkling wine. This study investigates the determinants of WTP for sparkling wine based on data from Portuguese consumers. The results provided by two alternative methodologies are compared: a traditional econometric model, based on the estimation of an ordered probit model; and a modelling approach based on data-driven and using machine learning algorithms. Both approaches present similar results, highlighting the relevance of some determinants including income, Champagne brand, not being a protected designation of origin and being a red wine consumer as main predictors of WTP for sparkling wine in Portugal.

Religious beliefs and social class identification: micro evidence from China.

Residents' sense of social class identity is of great significance for enhancing self-happiness and maintaining social stability. As a spiritual force, religious beliefs can significantly influence residents' subjective perceptions. Based on this, using data from the 2021 Chinese General Social Survey (CGSS 2021), this paper explores the impact of religious beliefs on residents' sense of social class identity through the probit model and Ordinary Least Squares (OLS) method, and analyzes potential mechanisms. The baseline regression results indicate that religious beliefs significantly enhance residents' sense of social class identity(p < 0.05), a conclusion that holds true even after rigorous robustness tests. Furthermore, female residents(p < 0.05), residents with lower education levels(p < 0.05), and those who believe in domestic religions(p < 0.05) exhibit higher social class identification compared to those who believe in foreign religions. Mechanism analysis suggests that economic capital and social capital play mediating roles, indicating that religious beliefs enhance the economic(p < 0.01) and social capital of believers(p < 0.01), thereby increasing their sense of social class identity. Therefore, this paper suggests respecting residents' religious beliefs, while religious organizations should actively adapt to the needs of social development, providing spiritual comfort and moral guidance to residents.

The Effect of Economic Uncertainty on Access to Finance: An Empirical Examination for European SMEs

This study examines the effect of economic uncertainty on the probability of access to finance for the years between 2015 and 2020. Survey on Access to Finance of Enterprises (SAFE) dataset is used for measuring the level of access to finance and The IMF World Uncertainty Index (WUI) is considered as a proxy for uncertainty. According to probit regression model results, the uncertainty negatively affects the probability of firms’ access to bank loans while positively affecting the likelihood of access to trade credit. The results also reveal that some firm-level and macroeconomic indicators significantly impact access to finance.

Determinants of smallholder wheat farmers’ participation in cluster farming in Lemu-Bilbilo and Hetosa Districts of Arsi Zone, Ethiopia

AbstractDespite devoting significant efforts to develop and implement policies aimed at enhancing the sustainability of its food systems, promoting resilience, and reducing greenhouse gas emissions, Ethiopia encounters constraints with these approaches. Therefore, this study was conducted to identify the determinants of smallholder farmers’ participation in wheat cluster farming in the Lemu-Bilbilo and Hetosa Districts of Arsi Zone, Ethiopia. The study utilized cross-sectional data and a multistage sampling procedure to select a total of 381 respondents from the two districts of Arsi Zone, Ethiopia. The study employed a binary probit regression to achieve the research objectives. The study indicates that sex of household head, farm size, household head education level, access to credit, membership in farmer’s cooperative, access to information from government extension, access to information on climate, and farmers climate perception were significant and positively affecting cluster farming participation, whereas distance from the nearest market and off-farm activities participation had a negative relationship with cluster farming participation decision. Cluster farming practices provide a practical means of lessening the effects of stresses related to climate change. Therefore, to increase participation in cluster farming, it is essential to strengthen efforts to raise awareness about climate change and its impacts among farming communities. The study also recommends that institutional and governmental support is essential in the areas of cooperatives, education, extension services, credit availability, climate-related information, and infrastructure development, especially in the area of market accessibility. Furthermore, the issue of gender differences in CF involvement should be addressed by policy and development initiatives.

Impact of financial literacy and education on breast and cervical cancer screening participation in Japan.

Despite government efforts, the uptake of screening for breast and cervical cancers among Japanese women remains low. This study employs financial literacy and financial education as proxies for rational decision-making to explore their potential to enhance cancer screening practices in Japan. Using data from Osaka University's Preference Parameters Study, mean comparison tests and probit regression models are utilized to examine the association between breast and cervical cancer screening and financial literacy and financial education. The results of probit regression show that individuals with higher levels of financial education tend to participate in both breast and cervical cancer screening. In contrast, individuals with higher financial literacy are likely to participate in breast cancer screening, whereas no significant impact is observed for cervical cancer screening. Furthermore, our findings reveal that financial education positively influences both breast and cervical cancer screening. Factors such as employment, marriage, higher education, increased household income, and greater assets demonstrate robust positive relationships with breast and cervical cancer screening. Meanwhile, psychological factors including happiness, a myopic view of the future, anxiety about later life, and perceived health status have no significant associations, except for a positive association between anxiety about life and cervical cancer screening. Our study suggests the development of targeted educational programs that leverage financial literacy and financial education to raise awareness about the importance of breast and cervical cancer screening.

Unlocking high-growth potential: does intellectual capital efficiency drive European entrepreneurial ventures?

PurposeThis paper investigates the influence of intellectual capital (IC) efficiency and its components – human capital efficiency (HCE), structural capital efficiency (SCE) and capital employed efficiency (CEE) – on the growth paths of small and medium-sized enterprises (SMEs) and their likelihood of becoming high-growth firms (HGFs).Design/methodology/approachDrawing on the resource-based view (RBV), our study reveals a positive relationship between IC efficiency and the likelihood of becoming HGFs. Using a longitudinal dataset of 554,076 firm-year observations corresponding to approximately 79,158 European SMEs from 2012–2019, our study employs probit regression to examine the impact of IC efficiency on the probability of becoming an HGF. To investigate the impact of IC efficiency across the growth rate distribution, we conduct further analyses via generalized least squares.FindingsThe results show that IC efficiency positively influences the growth paths of small entrepreneurial ventures and their likelihood of experiencing high-growth episodes.Practical implicationsFor practitioners, the findings underscore the importance of investing in IC to enhance the growth process of entrepreneurial firms and increase their likelihood of achieving HGF status. Investments in IC can maximize growth potential and competitiveness, informing strategic decision-making.Social implicationsPolicymakers should consider the critical role of IC in promoting SME growth and formulate policies that encourage the development of IC among entrepreneurial firms. Such initiatives can stimulate economic growth, innovation and job creation across European economies.Originality/valueThis study contributes to the literature by focusing on entrepreneurial firms and examining how IC efficiency drives their transition to HGF status. This study provides empirical evidence across several European contexts over an extended period, emphasizing the role of IC efficiency in shaping the growth paths of entrepreneurial firms.

BPE on contrast-enhanced mammography: relationship with breast density, age and menopausal status.

This retrospective study aimed to evaluate the relationship between BPE on CEM and breast density, age and menopausal status. Our analysis included all women eligible for CEM as a second-level examination in the diagnostic phase in a 12-month period. CEM were performed on a dedicated low-dose digital mammography unit after the injection of 1.5ml/kg body weight Iohexol 350 mgI/ml. Both breast composition and BPE were assessed independently by two breast radiologists according to the CEM supplement to the 2013 ACR BI-RADS Mammography. A two-stage ordered probit regression model was fitted to evaluate the relationship between BPE and the other factors considered. 49 patients were included (median age = 55years, 28.6% premenopausal and 71.4% postmenopausal). Breast composition was classified as ACR BI-RADS a in 4.1%, ACR BI-RADS b in 36.7%, ACR BI-RADS c in 46.9%, and ACR BI-RADS d in 12.2% of cases, by both Readers. A BPE 1 category was assigned in 53.1-55.1% of patients (by Reader 1 and 2, respectively), BPE 2 in 22.4%, BPE 3 in 18.4-12.2%, and BPE 4 in 6.1-10.2%. Higher breast density was strongly associated with higher levels of BPE, while BPE was not directly associated with age, both in fertile and postmenopausal patients. No significant differences were observed between the two Readers. Increased BPE is associated with a well-established breast cancer risk factor as high breast density, while it was not directly dependent on the other non-modifiable factors considered.

Evaluation of Fumigant Toxicity of Eucalyptus globulus Essential oil (Family: Myrtaceae) against the Mechanical Vector, American Cockroach, Periplaneta Americana (Linnaeus, 1758) (Blattodea: Blattidae)

The American cockroach, Periplaneta americana (Linnaeus, 1758), one of the largest and most resilient cockroach species, possess significant threats to public health and food safety due to its ability to transmit diseases and contaminate food. The widespread application of chemical pesticides to control cockroach infestations raises significant public health concerns due to its residual toxicity. The continued use of insecticides results in resistance development in cockroach populations which demands alternative pest management strategies wherein the chemical insecticides were completely restricted in human dwelling areas such as apartments, hospitals, restaurants and food preparation areas. The plant’s diverse profile of bioactive compounds and secondary metabolites, coupled with its complex nature, renders it a promising natural resource for the development of safe alternative against cockroach management. The median lethal dosage LD50 of E. globulus essential oil was found to be 16.74784 µL against the male American Cockroach, P. americana analysed using probit analysis. The present study was conducted to evaluate the fumigant toxicity of eucalyptus essential oil (Eucalyptus globulus) against the male American Cockroach, Periplaneta americana in a laboratory experiment. Five different doses of E. globulus essential oil 5, 10, 20, 30, 40 and 50 µL against male American Cockroach, P. americana were evaluated and compared to the untreated control (negative control). Results, indicated a dose dependent response with 100 per cent mortality achieved at 50 µL of eucalyptus essential oil followed by 40 (80%), 30 (60%), 20 (46.67%) and 5 (26.67) µL. The Eucalyptus globulus essential oil can be used as a potent fumigant against the male American Cockroach, P. americana which is an ecofriendly management of cockroach infestation.

Unveiling housing preferences amidst flood risks: an empirical study in an emerging market

Purpose This study investigates the interplay between flood risk, financial constraints and buyer behavior in the housing market. It aims to discern how flood experience influences housing choices, particularly among financially constrained buyers. Design/methodology/approach Using hedonic pricing models and probit analysis, this research examines the implicit prices of house characteristics and evaluates the determinants of housing choices, considering factors such as flood risk, financial status and past flood experience. Findings The study underscores that lower house prices incentivize buyers to opt for homes in flood-prone areas, thereby increasing their vulnerability to flood risks. Consequently, financial constraints exacerbate this situation, compelling low-income buyers to accept higher flood risks. However, flood experience fosters risk awareness among buyers, encouraging them to steer clear of flood-prone areas, albeit with lesser efficacy among financially constrained individuals. Originality/value This research contributes to the understanding of how flood risk and financial limitations shape housing decisions. It highlights the role of flood experience in influencing buyer behavior and emphasizes the need for targeted policies to mitigate flood-related risks in the housing market, particularly among economically vulnerable populations.

Effect of crystalloidsolution co-loading infusion rate on the dose requirements of prophylactic phenylephrine for preventing hypotension following combined spinal-epidural anesthesia for cesarean delivery.

Intravenous fluid administration and prophylactic vasopressor infusion are the primary methods for preventing spinal anesthesia-induced hypotension during cesarean delivery. However, evidence regarding the impact of different volumes of crystalloid solution on the phenylephrine infusion dosage for preventing this hypotension remains inconclusive. This study aimed to determine the effect of two IV fluid infusion rates (10 or 20 mL/kg/h) on phenylephrine requirement for preventing spinal anesthesia-induced hypotension. Eighty healthy parturients undergoing elective cesarean delivery under combined spinal-epidural anesthesia were enrolled. Participants were randomly assigned to receive either 10 mL/kg/h (group 10) or 20 mL/kg/h (group 20) of lactated Ringer's solution. The first patient in each group received 0.5µg/kg/min of phenylephrine infusion immediately after intrathecal injection. The phenylephrine dose in subsequent patients was adjusted by increments or decrements of 0.05µg/kg/min based on the previous patient's response. The ED50 of phenylephrine infusion for preventing spinal-induced hypotension for cesarean delivery was estimated using a modified up-down sequential analysis, with probit analysis applied as a backup sensitivity analysis. The ED50 values for preventing spinal anesthesia-induced hypotension were 0.30µg/kg/min (95% CI, 0.29-0.32µg/kg/min) for group 10, and 0.19µg/kg/min (95% CI, 0.16-0.22µg/kg/min) for group 20, respectively. The estimated relative potency for phenylephrine in group 10 compared to group 20 was 1.52 (95%CI, 1.24-1.97), showing a significant difference in the ED50 values between the two groups. This study found that a higher crystalloid co-loading rate significantly reduces prophylactic phenylephrine requirement for preventing spinal anesthesia induced hypotension. https://www.chictr.org.cn/showproj.html?proj=125918 (Trial number: ChiCTR2100048002).

Re-partnering and fertility

Abstract European divorce rates have been rising since the 1970s. Concurrently, as more couples choose cohabitation over marriage, there has also been an increase in separations among cohabiting partners. Nearly 50% of separated individuals form new relationships within five years. These trends may have important implications for fertility research. Are re-partnered women more likely to continue having children than women who have never separated? Do re-partnered women approach fertility decisions differently? Does re-partnering help recover the births 'lost' due to separation? To address these questions, we utilise longitudinal data from 2004 to 2018 across 32 European countries, employing probit models for our analysis. We find that women in higher-order unions are, on average, more likely to have an additional child compared to those who already have children with their current partner. The former group appears less burdened by having more or older children and is less influenced by family income. Predictions from our models indicate that births lost due to union dissolution can only be recovered when re-partnering occurs relatively quickly.

Does alcohol consumption cause poverty? Evidence from Vietnam

ABSTRACT This paper examines the impacts of alcohol expenditure on poverty. A main challenge of doing so is to remove the endogeneity arising from the bidirectional relationship between the two variables that seriously distorts the estimated correlation coefficients. This paper proves that an instrumental variable (IV) probit model outperforms the treatment effect and the panel probit models in terms of purging this endogeneity. When this IV probit model is applied to the Vietnamese data, the results show that alcohol expenditure increases the likelihood of consumers becoming poor; therefore, it is crucial to prioritize the regulation of alcohol spending as a fundamental element in the execution of poverty alleviation initiatives.

Land rights, resource allocation and urban settlement choices of migrant workers in Yunnan, Western China

Using the cross-sectional data from the 2015 and 2021 Yunnan Migrant Workers Urban Integration Survey, this study assesses the different effects of the three types of land rights that migrant workers possess in their rural hometowns on their urban settlement choices in Yunnan, western China. Specifically, it examined the existence of migrant workers moving between urban and rural areas in response to the importance of land rights for rural migrant workers, in western China, a region with the lower level of economic development and fastest growing number of migrant workers in China. After controlling for the impact of other variables, the multinomial Probit model was used to estimate the impact of the migrant workers' land rights in their rural hometowns on their settlement choices in urban areas. We found that rural land rights significantly increased migrant workers' willingness to return to their hometowns. This indicates that land right security is a key factor affecting Yunnan migrant workers' urban settlement intentions, although it is conditional in terms of age groups and places of origin. Importantly, we found that migrant workers in western China are more inclined to keep their dual identities as both urban migrant workers and rural residents. They, hence, are more inclined to rationally allocate their resources between urban and rural areas to maximize their economic outputs. Particularly, they prefer to only working - rather than settling - in urban areas, while retaining their rural land as assets and income sources. Instead of settling in either urban or rural areas, the older migrant workers who migrate to smaller and economically underdeveloped cities are more inclined to drift between urban and rural areas without permanent settlement. This confirms the argument of livelihood resource maximization and migratory bird-type migration as important mechanisms via which land right ownership affects migrant workers’ urban settlement intentions. This study suggests that policymakers should consider the land rights of rural migrant workers when making urban settlement policies, especially for small and medium-sized cities, where migrant settlement intention is weaker. Policymakers should also promote the flexibility of rural land use rights transfer and explore reforms concerning the separation of the three types of land rights to achieve a balance between urbanization and land use efficiency, particularly in small and medium-sized cities.

Effectiveness of military spending in reducing the intensity of armed conflict in Sub-Saharan Africa

Abstract This study empirically examines the effectiveness of military spending in reducing the intensity of armed conflict in Sub-Saharan Africa. We use a dynamic probit model, and the results show that military spending reduces the intensity of conflict. It significantly reduces low-intensity conflicts more than high-intensity conflicts. Additionally, the effectiveness of military spending depends on its level and the quality of institutions. Finally, the analysis of transmission channels shows that military spending affects conflict intensity mainly through the channel of military capabilities. We conducted several tests and robustness checks to ensure the validity of our results.

Determinants of Microfinance Demand (Evidence from Chiredzi Smallholder Resettled Sugarcane Farmers in Zimbabwe)

Despite the MFI insurgency, agricultural financing remains critically low, even though microcredit is widely accepted as both a substitute and compliment to formal credit. Zimbabwe is an agro-based economy and very little is known about the determinants of microcredit demand and microcredit size in smallholder resettled sugarcane farmers. Research is concentrated in short-term agriculture activities. Thus, this study aims to fill the unattended gap in lagged returns agriculture activities such as sugarcane production which takes at least a year to mature, hence, the greater need for agriculture financing alternatives such as microfinance. The study examined the determinants of both microcredit demand and loan size (magnitude of microcredit participation) by smallholder resettled A2 sugarcane farmers in Chiredzi. Primary data from 370 smallholder resettled sugarcane farmers (214 borrower participants and 156 non-borrower participants) were used. Probit and Tobit regression models were used for data analysis in STATA. Operational costs, interest rate, grace period, and land size significantly affect both the demand for microcredit and microcredit size, while education, household farming assets, extension services, and payback period significantly affect microfinance demand, and risk attitude/perception additionally determine microcredit size. Special microfinance schemes best suitable for the agriculture sector and crop/plant-specific agriculture financing schemes, currency, and macroeconomic stability are the major policy recommendations.

Disentangling the gender-differentiated determinants of home-based self-employment choices in Nigeria

Abstract Understanding gender disparities in home-based self-employment (HBS) and their links to homeownership and socioeconomic factors is crucial for advancing sustainable development goals (SDGs) in Sub-Saharan Africa, especially Nigeria. This study uses data from the 2010/2011, 2012/13, 2015/16, and 2018/19 waves of the Nigerian General Household Survey (GHS). It employs random effect probit regression, the LASSO method for identifying predictors, and the Blinder–Oaxaca decomposition technique to analyse gender differences in nonlinear binary outcomes. The results show that female business owners are more likely to engage in HBS compared to males, highlighting the importance of gender equality (SDG 5) and decent work (SDG 8). While male entrepreneurs are mainly driven by profit, females prioritise balancing paid and unpaid work, reflecting motivations beyond profit within heterodox economics. Significant gender-differentiated impacts are observed in relation to monthly rent, post-secondary education, dwelling space, energy, and regional locations. Notably, the presence of children significantly increases female involvement in HBS, a trend not seen among males. Marriage also influences female participation, suggesting that marital circumstances and economic benefits play a role. These findings highlight the need for policies addressing gender-specific constraints, challenging traditional gender roles, and promoting inclusive human development within the SDG framework.

Evaluating factors influencing youth participation in agricultural enterprises: Implications for food security and agribusiness

Background: Agriculture is crucial for economic growth, yet youth engagement in agricultural enterprises is declining due to concerns related to perceived profitability, resource access, and social stigmas. Understanding these determinants is vital for fostering youth interest in agriculture and promoting sustainable rural development and food security.Aim: This study examines the factors affecting youth engagement in agricultural enterprises in Umzimvubu Local Municipality, South Africa, and their implications for food security and agribusiness.Setting: Addressing youth unemployment and enhancing agriculture’s contribution to gross domestic product (GDP) require understanding barriers to youth participation. This study was conducted in Umzimvubu Local Municipality, South Africa.Methods: A structured questionnaire was administered to 210 youths through stratified random sampling. Descriptive statistics and a univariate probit regression model were used for analysis.Results: Findings indicate male dominance in agriculture, with educational background positively correlating with participation. Single youths showed greater interest than married counterparts. Challenges like land availability and a lack of financial support hinder engagement. Significant determinants include age, education, farming skills, social group membership, and household revenue, while factors like household size, gender, and limited access to credit negatively impact willingness to participate.Conclusion: Addressing financial barriers through improved access to loans is essential to enhance youth involvement. Policies should cater to youth-specific traits and environmental challenges to build a resilient agricultural sector driven by young innovators.Contribution: The study emphasises the need for a comprehensive policy framework collaboratively developed by the government, the Department of Agriculture, and non-governmental organisations.

Impact of agricultural extension services on rice productivity and profitability in Bangladesh

Agricultural extension services play a pivotal role in promoting sustainable agriculture, particularly in developing countries where many farmers are resource-poor. Enhancing farmers’ profitability and productivity is essential to meet the increasing demand of a growing population. This study aims to examine the impact of agricultural extension services on the profitability and productivity of rice farmers in Bangladesh. The analysis uses unbalanced panel data from the International Food Policy Research Institute’s Bangladesh Integrated Household Survey for 2015 and 2018. The Mann–Whitney U test was used to assess whether the differences between the participant and non-participant groups were statistically significant. Additionally, a probit regression model is used to identify the determinants of participation in agricultural extension services. The findings reveal that participation is positively influenced by access to subsidies, distance to market, occupation and livelihood vulnerability. The impact of agricultural extension services on farm productivity and profitability is assessed using difference-in-difference and random effect generalized least squares models. The results show that agricultural extension services significantly contribute to both farm profitability and productivity. This suggests that governments should intensify and monitor the delivery of agricultural extension services, particularly focusing on the timely provision of support resource-poor farmers.

Effect of Lidocaine on Ciprofol Dosage and Efficacy in Patients Who Underwent Gastroscopy Sedation.

BACKGROUND Intravenous ciprofol is a short-acting sedative with minimal respiratory and circulatory suppression and limited analgesia. Intravenous lidocaine provides analgesia during surgical procedures. This study included 70 patients who underwent gastroscopy with analgesia and aimed to evaluate the effects of intravenous lidocaine on the dose of ciprofol required to produce 50% of the maximal effect (ED50). MATERIAL AND METHODS Seventy patients scheduled for elective painless gastroscopy were randomly assigned into 2 groups: group L (n=35, received ciprofol and 1.5 mg/kg lidocaine) and group S (n=35, received ciprofol and normal saline). The primary outcomes measured were the ED50 and the 95% effective dose (ED95) of ciprofol, determined using the modified up-down sequential method and Probit analysis. Secondary outcomes included induction, operation, and recovery times; monitoring of vital signs such as mean arterial pressure, heart rate, and oxygen saturation; and evaluation of postoperative adverse reactions, including sore throat, nausea, vomiting, abdominal pain, and satisfaction scores from endoscopists and anesthesiologists. RESULTS The ED50 of ciprofol in group L was 0.315 mg/kg (95% CI, 0.291-0.342 mg/kg), which was significantly lower than that in group S, 0.42 mg/kg (95% CI, 0.371-0.491 mg/kg). Additionally, group L exhibited shorter induction and recovery times, a lower incidence of postoperative sore throat, and a temporary drop in blood pressure following induction. CONCLUSIONS Intravenous lidocaine during painless gastroscopy reduces the required ciprofol dose, shortens induction and recovery times, and lowers the incidence of postoperative complications, such as sore throat. These findings support its effective role in improving sedation quality and patient outcomes during gastroscopy.
