This paper estimates the financial returns to higher education quality in the UK. To account for the selectivity of students to institution, we rely on a selection on observable assumption. We use several estimates including the Generalised Propensity Score (GPS) of Hirano and Imbens, which relies on a continuous measure of institutional quality. This highlights that the returns to quality are heterogeneous and mostly driven by high-quality institutions. Moving from an institution in the third quality quartile to a top quality institution is associated with a 7% increase in earnings.

Users' knowledge contribution behaviors are critical for online Q&A communities to thrive. Well-organized question threads in online Q&A communities enable users to clearly read existing answers and their evaluations before contributing. Based on the social comparison and peer influence literature, the authors examine peer influence on the informativeness of knowledge contributions in competitive settings. The authors also consider three levels of moderating factors concerning individuals' perception of competitiveness: question level, thread level and contributor level.

The authors collected data from one of the largest online Q&A communities in China. The hypotheses were validated using hierarchical linear models with cross-classified random effects. The generalized propensity score weighting method was employed for the robustness check.

The authors demonstrate the peer influence due to social comparison concerns among knowledge contribution behaviors in the same question thread. If more prior knowledge contributors choose to contribute long answers in the question thread, the subsequent contributions are more informative. This peer influence is stronger for factual questions and questions with higher popularity of answering but weaker in recommendation-type and well-answered questions and for contributors with higher social status.

This research provides a new cue of peer influence on online UGC contributions in competitive settings initiated by social comparison concerns. Additionally, the authors identify three levels of moderating factors (question level, thread level and contributor level) that are specific to online Q&A settings and are related to a contributor's perception of competitiveness, which affect the direct effect of peer influence on knowledge contributions. Rather than focus on motivation and quality evaluation, the authors concentrate on the specific content of online knowledge contributions. Peer influence here is not based on an actual acquaintance or a following relationship but on answering the same question. The authors also illustrate the competitive peer influence in subjective and personalized behaviors in online UGC communities.

The aim of this study is to evaluate five job qualification programs for young apprentices, in Goiás, a Brazilian State. We expect to contribute to the improvement and strengthening of the job training programs in developing countries.

We applied propensity score matching and extensions such as the generalized propensity score method (dose–response effect).

We found evidence of the heterogenous effects of the five job qualification programs on employability. We found that the duration of the programs influences employability in up to two years after the program.

This research is based on secondary data provided by the responsible institutions. The evidence is obtained through a nonexperimental method.

The research has implications for public or private institutions dedicated to the professional qualification of young apprentices.

The findings of the study provide some ways of comparing training programs, for young workers, that can be applied in different types of institutions.

This study provides new insight about the professional qualification of young apprentices, by comparing fives programs in Midwest Brazil.

The purpose of this paper is to investigate the relationship between the characteristics of the incubation industry, government funding, and the intensity of funding for different services. Because the incubation industry has particular characteristics, government funding varies for different services, and its intensity varies with service.

Government funding is classified as incubation subsidy and incubation incentive. Besides, incubation services include property management, business mentoring as well as investment and financing. Based on this, this study examines the influence mechanism of different subsidy and incentive on incubation services by using the generalized propensity score matching method.

The empirical results show that subsidy and incentive have an inverse-U shape effect on property management service, but a linear effect on business guidance service. Furthermore, subsidy does not affect investment and financing service, but incentive that can have a significant impact.

The theme of government funding and incubator services plays an important role in helping entrepreneurs expand their businesses. Incubation subsidy and incentive can provide important support to help enterprises obtain more preferential loans, technical services and technical support in the incubator. Applying it to incubator services can provide better technology and entrepreneurship guidance. These services can help new entrepreneurs understand products and markets, and how to develop more successfully in the early stage. In short, incubators supported by government funds can provide important support to entrepreneurs to help them successfully realize their business plans.

The purpose of this paper is to determine the impact of microcredit on smallholder poultry production and its subsequent role on domestic protein and food supply.

Cross-sectional farm-level data from 61 farmers with at least two years of microcredit access and 39 farmers without microcredit access in the Dormaa Municipality of Ghana collected in 2016 via semi-structured questionnaire were used. Using the propensity score matching, PSM, and data envelopment analyses approaches, the authors analysed the propensity of farmers’ taking microcredit and its effect on beneficiaries’ technical efficiency, productivity, profitability and domestic production of chicken and eggs, farm performance. The authors addressed selection biases with the PSM and answered the research question of whether farmers with microcredit access perform better than non-microcredit farmers.

Farmers with high years of education, farming experience, technology and machinery as well as micro-savings and female farmers are more likely to take microcredit whereas large farm size reduces farmers’ propensity to take microcredit. Furthermore, farms with microcredit access were more technically efficient, productive and profitable than they would have been in the absence of microcredit.

The paper can be useful to policymakers and microcredit institutions since it provides evidence of microeconomic impacts of microcredit on agricultural production and the determinants of farmers’ participation in microcredit.

The study helps to understand how access to credit can improve smallholders’ technology adoption, production efficiency and productivity and output thereby enhancing domestic food supply.

Transformation of smallholder agriculture from subsistence to more commercially-oriented production is one of the strategies advocated for improving rural households' food security and general welfare. The purpose of this paper is to assess potential differential effects of smallholder commercialization intensity on the different dimensions of food security.

Using household data from rural Tanzania, the study employed Tobit regression and Generalized Propensity Score (GPS) approaches to analyze smallholder commercialization intensity and associated food security effects.

Results show that smallholder commercialization has heterogeneous effects on the different dimensions of food security. Specifically, lower levels of commercialization are associated with lower food availability, access, utilization and stability. At higher intensities of commercialization, smallholders have higher food availability and access but modest improvements in food utilization and stability. Findings suggests that heterogeneous effects of commercialization on food security and the multi-dimensional nature of food security are important aspects to consider in the design of strategies to improve smallholder agriculture for enhanced food security and welfare.

It is important to point out that while food security is still a complex phenomenon, one that cannot be analyzed easily, so is commercialization. This study has used only one of the many definitions of commercialization.

Most existing literature on smallholder commercialization groups farmers into commercial and subsistence-oriented households. However, smallholders commercialize at various levels of intensity. This paper, conversely, analyzes the potential effects of different levels of commercialization on the various aspects of food security. Further, unlike extensive literature that focus on a narrow definition of food security, this paper expands the evidence of the implications of smallholder commercialization on the different dimensions of food security namely, food availability, access, utilization and stability.

Motivated by the enactment of non-financial reporting regulations by the European Parliament, this paper aims to investigate the impact of European Union (EU) directive 2014/95/EU on the quantity of environmental, social and governance (ESG) disclosures by the S&P Europe 350 index firms. This study also investigates whether the implementation of the non-financial information (NFI) reporting regulations influences the association between ESG disclosures and firms’ earnings risk.

To measure the impact of mandatory regulations on the quantity of ESG disclosures, this study estimates the average treatment effects using a propensity weighted sample. Then this study uses the difference-in-differences method to estimate the differences in the association between ESG disclosures and earning risk before and after implementation of the EU directive.

The results show a significant positive impact of the EU directive on the quantity of ESG disclosures for the sample European public-interest entities, which indicates that the mandatory NFI reporting requirements could boost the availability of increasingly demanded ESG related information. The enhanced association between the ESG disclosures and firms’ earnings risk during the post-directive period reveals that mandating NFI reporting also increases the quality of ESG disclosures.

Using the legitimacy and decision-usefulness theories, this study provides novel evidence concerning the impact of the EU directive on the quantity and quality of ESG disclosures.

This chapter studies the large sample properties of a subclassification-based estimator of the dose–response function under ignorability. Employing standard regularity conditions, it is shown that the estimator is root-n consistent, asymptotically linear, and semiparametric efficient in large samples. A consistent estimator of the standard-error is also developed under the same assumptions. In a Monte Carlo experiment, we investigate the finite sample performance of this simple and intuitive estimator and compare it to others commonly employed in the literature.

Theory suggests that the market for corporate control, which constitutes an important external governance mechanism, may substitute for internal governance. Consistent with this notion, using a novel measure of takeover vulnerability primarily based on state legislation, this paper aims to investigate the effect of the takeover market on board characteristics with special emphasis on board gender diversity.

This paper exploits a novel measure of takeover vulnerability based on state legislation. This novel measure is likely exogenous as the legislation was imposed from outside the firm. By using an exogenous measure, the analysis is less vulnerable to endogeneity and is thus more likely to show a causal effect.

The results show that a more active takeover market leads to lower board gender diversity. Specifically, a rise in takeover vulnerability by one standard deviation results in a decline in board gender diversity by 10.01%. Moreover, stronger takeover market susceptibility also brings about larger board size and less board independence, corroborating the substitution effect. Additional analysis confirms the results, including propensity score matching, generalized method of moments dynamic panel data analysis and instrumental variable analysis.

The study is the first to explore the effect of the takeover market on board gender diversity. Unlike most of the previous research in this area, which suffers from endogeneity, this paper uses a novel measure of takeover vulnerability that is probably exogenous. The results are thus much more likely to demonstrate causality.

This study examines the impact of participation in a STEM Enrichment Summer Bridge Program, funded by the NSF Houston-Louis Stokes Alliance for Minority Participation, on undergraduate student success outcomes, particularly for under-represented students.

The study uses propensity score matching and logistic regression analysis to examine the effects of participation in the STEM enrichment program on graduation and retention in STEM after matching on baseline socio-demographic and pre-college characteristics.

The analysis found that program participation had a significant effect on increasing both the graduation rates and retention of under-represented minority students in STEM fields. In addition, results indicated that program participation had a particularly strong impact for Pell-eligible students in terms of course grades.

Data obtained for this study were limited to a single Hispanic-serving/Asian-serving institution, and therefore are not necessarily representative of the graduation and retention trends of the larger population of underrepresented minority (URM) students across the nation.

This study uniquely adds to the existing body of literature surrounding the retention of URM students in STEM fields by accounting for baseline variables, such as pre-college academic achievement and socio-demographic characteristics, that could lead to bias in estimating results. Specifically, this study addresses limitations of previous studies by comparing participants and non-participants of the STEM enrichment program who are matched on a selection of baseline characteristics.
