This study employs the correspondence test method to investigate discrimination in access to sports clubs in France. This involves sending requests for information to sports clubs. Eight fictitious candidate profiles were created to assess three discrimination criteria: gender, ethnic origin, and income level. The profiles sent emails to 1,200 sports clubs, requesting information on access to training for four different sports, chosen for their highly gendered practices. The results demonstrate the absence of quantitative discrimination in three of the four sports tested. Nevertheless, there is a considerable disadvantage for the three criteria in horseback riding, a sport with considerably higher practice costs than the other disciplines under investigation. Furthermore, the content of the emails received suggests a preference for the reference candidate over the North African and opposite-sex candidates.

We show that a firm’s profits under Cournot oligopoly can be increasing in the number of firms in the industry if wages are determined by (decentralised) bargaining in unionised bilateral oligopoly. The intuition for the result is that increased product market competition following an increase in the number of firms is mirrored by increased labour market rivalry which induces (profit-enhancing) wage moderation, a result which does not occur if unions can coordinate their wage demands under centralised bargaining. Whether the product or labour market effect dominates depends on the nature of union preferences, with a higher preference for wages making profit-raising entry more likely. We analyse how our results are sensitive to the curvature of the demand function, and the extent to which structural advantages due to incumbency enhance the benefits of entry. We also consider: (i) the impact of entry on a measure of social welfare comprising union utility, consumer surplus and firms’ profits, and (ii) a setting in which unionisation is determined endogenously through the decision of firms on whether or not to recognise unions.

The BRICS countries have a significant influence on global environmental issues, ranking among the world's top polluters. Similarly, they possess the world's largest foreign exchange reserves. Nevertheless, this intriguing intertwining has not been investigated. This research gap inspired the study to examine how environmental conditions react to the accumulation of international reserves and to explore the potential existence of an inverted U-shaped relationship between 1993 and 2020. The empirical findings using Method of Moments Quantile Regression (MMQR) indicate an inverted U-shaped relationship between international reserves and environmental degradation in the BRICS countries. Initially, reserve accumulation is harmful to the environment, suggesting a prioritization of reserve accumulation over environmental sustainability. However, once a certain level is reached, reserves start to help protect the environment. Additional findings reveal that nonrenewable energy consumption, GDP, and population negatively affect the environment, whereas exports have a positive influence. The impact of FDI, however, is inconsistent and frequently lacks significance over time. Furthermore, the causality analysis supports all of the aforementioned findings.

This research aims to examine the influence of environmental tax, green innovation, and digital financial inclusion on energy transition in OECD countries during the period from 1994 to 2020. Results from the panel quantile regression analysis reveal that environmental tax positively influences the energy transition at the lower and middle quantiles whilst financial inclusion is positively associated with energy transition across all quantiles. Our results also show a positive relationship between green innovation and energy transition, though the lack of significant coefficients across all quantiles suggests a disparity between green innovation and immediate energy transition outcomes. Our findings highlight the need for regulatory agencies to design a flexible and fair environmental tax system, particularly in applying taxes according to the pollution intensity of different energy sources.

This paper builds on Clague's argument that countries with skilled workers have lower costs for producing nontradable services, leading to a lower price level. It formalizes this idea in a model and validates it empirically using data from 95 countries over five decades. The analysis shows a significant negative effect of workforce education on the price level, confirming the Clague effect. However, this effect has diminished in the last two decades, likely due to skill-intensive services becoming more tradable through international e-commerce. The study highlights omitted variable bias in Balassa-Samuelson hypothesis tests, as they often exclude workforce skill level, which affects price level and productivity.

In this paper, we explore the agglomeration effect of culture on foreign direct investment (FDI). Using data on US FDI to 74 host countries from 1984 to 2017, our analysis shows a negative effect of bilateral cultural distance on US FDI to a host, consistent with previous studies. Central to our research is the application of a higher-order spatial model, which enables us to examine correlations of FDI across various hosts along both geographical and cultural dimensions. We find that US FDI across culturally similar host nations move together. Specifically, our results show that US FDI in a host may rise by 0.25% with every 1% increase in US FDI in other hosts that are culturally similar to the host of interest. Such results are robust to a battery of sensitivity checks, such as controlling for spatial correlation of geographically proximate hosts. Further, the agglomeration effects also display significant variations across industries.

This study investigates the impact of Vermont's Act 166 of 2014, which established universal pre-kindergarten, on birth rates among women aged 20–44. Contrary to the expectation of increased fertility, no meaningful increase in total, first, or subsequent birth rates was observed after program implementation. This aligns with existing research suggesting limited effectiveness of pronatalist policies. However, subsequent birth rates in Vermont declined at a slower rate than first birth rates compared to a synthetic control group, hinting at a potential positive influence on existing parents' decisions to have additional children.

This study evaluates the risk associated with capital allocation in cryptocurrencies (CCs) using a basket of 27 CCs and the CC index EWCI-. We apply basic statistical tests to model the body distribution of CC returns. Consistent with prior research, the stable distribution (SDI) is the most suitable model for the body distribution. However, due to less favorable properties in the tail area for high quantiles, the generalized Pareto distribution is employed. A combination of both distributions is utilized to calculate Value at Risk and Conditional Value at Risk, revealing distinct risk characteristics in two subgroups of CCs.

This study examines how the abundance of natural resources influences income inequality in India for the period 1971 to 2020. The study employs the Lee and Strazicich unit root test to identify structural break in the data, the Bayer-Hanck test of Co-integration and, methods for example FMOLS, DOLS and CRR to estimate long run coefficient. Further, to determine the direction of causality among the variables, Pairwise Granger Causality Tests is used. The results of Bayer-Hanck test for Co-integration confirms the presence of long-run association among variables. Empirical results show that income inequality is positively and significantly related with natural resources, urbanization, digitalization and physical capital, while it is negatively associated with human capital. The Granger Causality test reveals a bidirectional causal relation between natural resources and digitalization, whereas a unidirectional causal relationship is observed from human capital and physical capital to income inequality. The result of this study recommends policymakers, addressing income inequality in India requires effective and equitable allocation of resources, ensuring digital inclusion of its citizens, economic integration, promoting sustainable urban development and investment in both human and physical capital.
本研究考察了1971年至2020年期间印度自然资源的丰富程度如何影响收入不平等。本研究采用Lee and Strazicich单位根检验来识别数据中的结构断裂,采用bayer - hank协整检验,采用FMOLS、DOLS、CRR等方法估计长期系数。此外,为了确定变量之间的因果关系方向,使用了成对格兰杰因果关系检验。协整的bayer - hank检验结果证实变量之间存在长期关联。实证结果表明,收入不平等与自然资源、城市化、数字化和物质资本呈显著正相关,与人力资本呈负相关。格兰杰因果检验表明,自然资源与数字化之间存在双向因果关系,而人力资本和物质资本与收入不平等之间存在单向因果关系。这项研究的结果建议政策制定者,解决印度的收入不平等问题需要有效和公平的资源分配,确保其公民的数字包容,经济一体化,促进可持续的城市发展以及人力和物质资本投资。

We applied a method of estimating multiple effect sizes to agricultural efficiency data in Ghana. We used multi-efficiency data from 195 publications and 345 observations and fitted it to ordinary least squares regression to illustrate how the model works. The data is unique in the meta-regression efficiency space, containing all efficiency measures. We depart from existing frontier efficiency meta-regression by estimating the combined effect sizes of technical efficiency and other dimensions of frontier efficiency. We extended the single effect size estimation model to a multiple effect size estimation model. The application of the data showed that the strongest differences related to profit efficiency, the meta-regression of which has never been published. The average of the arithmetic means should not be considered as the overall efficiency, rather, the combined effect size in frontier efficiency meta-regression models.
