Peer heterogeneity,school tracking and students’ performances: evidence from PISA 2006

This paper analyses the interaction between school-tracking policies and peer effects in OECD countries. Using the Programme for International Student Assessment (PISA) 2006 data set, we show that linear peer effects are slightly concave-shaped in both early-tracking and comprehensive educational systems, but generally stronger in the early-tracking one. Second, and more interestingly, the effect of peer heterogeneity goes in opposite directions in the two systems. In both student- and school-level estimates, peer heterogeneity reduces students’ achievements in the comprehensive system while it has a positive impact in the early-tracking one. This reversal effect is robust to different definitions of early-tracking system, to the inclusion of pseudo-school fixed effects and to the exclusion of outlier countries. Finally, peer effects are stronger for low-ability students in both groups of countries.     

Effects of attending preschool on adolescents’ outcomes: evidence from China

This study examines whether attending preschool enhances the cognitive abilities, health and socialization of junior high school students in China. Using propensity score matching to control for a rich data set of student, family and school characteristics, I find that attending preschool enhances cognition among seventh graders but those gains fade among ninth graders. The greatest benefits from preschool accrue to both seventh and ninth graders from economically disadvantaged families. Results for non-cognitive categories are mixed, and no evidence suggests superior health outcomes. Evidence also shows cognitive benefits among adolescents – especially those economically disadvantaged – who entered preschool earlier.     

Catching up? The educational mobility of migrants’ and natives’ children in Europe

Migrants into European countries are often less educated than European natives. We analyse whether migrants’ children are more or less likely than natives’ children to achieve upward educational mobility across generations, and study differences in the factors, which contribute to differences in mobility for the two groups. We find that migrants’ descendants are more often upwardly mobile (and less often downwardly mobile) than their native peers in the majority of countries studied, and show that the main factor contributing to these patterns is the education level of parents. Although a lower parental education means that their children are less likely to access the same amount of human, social and financial capital as children of more highly educated parents, migrants’ descendants over the last two generations were able to make significant progress in reducing education gaps with natives.     

Workforce gender effects on firm performance and workers’ pay: evidence for the UK

Using linked workplace–worker data for the UK, a number of hypotheses are tested related to individual gender and the gender composition of the workforce. The proportion of female workers per establishment is strongly negatively associated with median workplace pay. There is some evidence that workplace performance (but not employment size or growth) is positively associated with the female–male workforce ratio. For workers, the female wage penalty (which is substantial) is strongly influenced by the female–male workforce ratio. In addition, commensurate with gender discrimination, those who manage female workers receive lower wages but professional workers in the same establishments do not.     

The effects of households’ and firms’ borrowing constraints on economic growth

This paper considers an endogenous growth model with asymmetric information between lenders and borrowers, that leads to credit-rationing a proportion of borrowers. However, in contrast to the existing literature, in this model, both firms and consumers face borrowing constraints. Nonetheless, the borrowing constraints facing a firm and those encountered by a consumer have opposing effects on growth. Relaxing borrowing constraints on firms is growth-promoting, as more funds become available for productive investment. In contrast, relaxing borrowing constraints facing consumers has a detrimental effect, as funds are diverted from productive investment to consumption. Such an adverse effect may offset the externality effect present in the production function that would otherwise ensure perpetual growth. Furthermore, it is shown that the interaction between households’ and firms’ borrowing constraints may give rise to endogenous cycles.     

R&D spillover effects on firms’ export behavior: evidence from South Korea

This paper investigates the spillover effects of R&D investments made by foreign multinational enterprises (MNEs) and domestic firms on their export activities, using a manufacturing firm-level panel dataset from South Korea. The theoretical framework predicts two conflicting spillover effects: positive technology spillovers and negative market rivalry spillovers. Thus, the net spillover effect is determined by the relative degree of the two conflicting spillovers. The empirical results show that negative intra-industry spillovers exist from the R&D of foreign MNEs on the export performance of firms, which implies that, in general, negative market rivalry spillovers dominate positive technology spillovers. However, notably, in the case of firms equipped with absorptive capacity, the negative spillovers can be alleviated; firms can gain positive spillovers by muting negative ones. Firms without absorptive capacity cannot avoid such negative effects. This paper shows that absorptive capacity is vital in capturing positive spillovers as firms build competency by accumulating their own know-how and improving their ability to capture better external technologies.     

The effects of old and new media on children’s weight

Childhood obesity rates have recently been rising in many countries. It has been suggested in the literature that changes in children’s media exposure may contribute to explaining this trend. I investigate whether or not this hypothesis is supported by data. I contribute to the literature by focusing not only on television but also on new media – computers and video games. The Child Development Supplement to the Panel Study of Income Dynamics is used for the analysis. To address the endogeneity of children’s media exposure, I use dynamic and panel data models. This is another improvement upon the existing literature. Additionally, an extensive list of control variables is included in the regressions. I find that video game playing or computer use has no effect on children’s body weight. On the other hand, television viewing may increase children’s body weight slightly.     

Differential effects of mother’s and child’s postnatal WIC participation on breastfeeding

We evaluate the effect of postnatal participation in the Women, Infants, and Children (WIC) programme on breastfeeding decisions using the data from the IFPS II. We find that the infant’s WIC participation positively affects the hazard of discontinuing breastfeeding, both partial and exclusive (and is thus associated with abbreviated breastfeeding duration). No significant association is found between the mother’s participation and the hazards of stopping exclusive or partial breastfeeding. Such differential effects might be a result of the programme’s policy, according to which the infant, but not the mother needs to be enrolled to receive free formula.     

The effects of human resource management on small firms’ productivity and employees’ wages

This paper analyses whether employees and firms differently benefit from particular human resource (HR) practices. The focus is on small firms that may be badly informed on the impact of HR practices on firm performance. In this study on Dutch pharmacies, it is found that firms do not reward employees’ skills according to their contribution to firms’ productivity, as (1) employees are over-rewarded for their sector-specific skills and under-rewarded for the productivity enhancing effect of their computer skills and (2) employees’ work experience positively affects their wages but does not have real productivity effects. Moreover, it is found that training employees in case of vacancy problems seems to be an adequate HR practice, since it increases productivity without affecting the average wage level. The opposite holds for offering higher wages to newly recruited employees. Furthermore, we find that only the employees benefit from performance evaluation interviews, whereas employing many employees by temporary contracts appears to have a negative effect on productivity, without affecting the wage level.     

The impact of science and technology parks on firms’ product innovation: empirical evidence from Spain

Science and Technology Parks (STP) have attracted considerable attention and public funds in recent years. However, the conclusions on their effectiveness remain mixed. This work evaluates the impact of STP on firm product innovation in the Spanish context, as an example of a less developed innovation system in which regional and national governments are prioritizing STP initiatives. This work draws on a large sample of firms provided by the Spanish Survey on Technological Innovation that is conducted annually by the National Statistical Institute. We explore alternative econometric methods to obtain average treatment effects for firms located in 22 Spanish STPs. Our results show that Spanish STPs have a strong and positive impact on the probability and amount of product innovation achieved by STP located firms. These results hold when the endogeneity of STP location is taken into account.     

The effects of local govemment investment on economic growth and employment： evidence from transitional China

Based on the panel data of 28 provinces in the year of 1987-2001, this paper examines the effects of the local government investment on economic growth and employment. The empirical result shows that the local government investment plays a significant positive role in economic growth and employment. However, while the proportion of local government investment to GDP had a remarkable rise after 1998, the elasticity of local government investment on economic growth declined, which shows that there is a big room for raising the efficiency of local government investment. Moreover. the empirieal examination shows that although local government investment had positive effect on employment, the elasticity had a decrease after 1994 when the tax-sharing system reform was put into practice. This shows that the positive role of local government investment on employment is also limited This paper argues that the role of local governments as investors must be weakened, and local governments of different levels should lessen direct economic intervention and concentrate on public regulation.     

Assessing the effect of educational programs on public schools’ performance

This paper provides evidence on the effectiveness in the implementation of an educational program which offered public schools in Catalonia (Spain) the opportunity to improve the quality of educational provision. We employ a difference-in-differences approach on rich balanced panel data of public schools. The results confirm that the program did effectively improve students’ achievement and reduce absenteeism, albeit not for all modules and school types or across all years. Our results highlight that it is important to condition the delivery of resources upon specific academic goals depending on the characteristics of the treated population. Additionally, program results suggest the need to enhance educational program design in order to get better evaluation feedback.

Labour effects of foreign and domestic remittances – evidence from Pakistan

Remittances are playing an increasingly important role in the economies of developing countries. In this paper, we study the effects of these flows on Pakistan’s labour market. We employ the 2007–2008 Household Integrated Economic Survey and Probit as well as Propensity Score Matching techniques to examine the impact on labour participation, quantity of work and activities of working as well as non-active members of remittance-receiving households. We find that both foreign and domestic remittances tend to lower labour supply of the recipient households. This impact is higher among women and among the young. The impact is more pronounced in the rural areas. In addition, foreign remittances increase the likelihood of household members attending middle school. We also examine the quantity of labour supplied by the remittance-recipient households. Results show little difference in the number of months and days worked between the households receiving and not receiving remittances. Furthermore, we find that the likelihood of being self-employed and cultivating one’s own land is higher among remittance recipients. In sum, our analysis highlights a higher role of foreign remittances in the labour market as compared to internal remittances.     

The true effect of students’ employment on the duration of studies

We examine the effect of the first-degree students’ employment on the prolongation of their studies. When employing a popular instrumental variable, the regional unemployment rate, we find a negative impact of students’ employment on duration of studies. Then, adding a predetermined IV – the individual’s employment prior to the beginning of academic studies – turns the estimate positive. Furthermore, we find that the relationship between the extent of students’ employment and duration of their studies depends on their age: among the younger students (aged 22–26), the extent of employment has no effect on the duration of studies, while among the older students, the effect is positive and statistically significant.     

On the incentive effects of monitoring: evidence from the lab and the field

Several experimental studies have shown that the crowding-out effect of monitoring may outweigh its disciplining effect through intrinsic motivation destruction, thereby reducing effort. However, most of these experiments use numeric effort tasks that subjects may not be intrinsically motivated to complete. This paper aims to analyze the incentive effects of monitoring using a real-effort task for which intrinsic motivation is more likely to exist. We conducted two similar experiments, in the lab in Montreal and in the field in Ouagadougou. In contrast to the lab, subjects in the field are unaware they are taking part in an experiment.     

IPOs’ signalling effects for speculative stock detection: evidence from the Stock Exchange of Thailand

Using a unique data set from the Thai stock market about the so-called, ‘Turnover List (TOL)’ of speculative stocks spanning the period 2004–2012, we investigate and provide new evidence on the relationship between IPOs’ pricing effects and subsequent classification as speculative investments. To be more specific, we examine the signalling effects for the detection of speculative stocks in relation to the degree of their prior IPOs underpricing. We also employ the market-feedback hypothesis to investigate this signalling process. Our results reveal a significant positive relationship between the magnitudes of the IPO underpricing and the probability of an IPO firm being classified officially as speculative on the TOL. Furthermore, we find that a 6-month abnormal return after going public increases the probability of speculative dealing in the IPOs. Next, we consider all listed firms in the Thai stock market and highlight the role of both abnormal return and trading volume in the transmission of probability for appearing on the TOL. In addition, we find that IPOs and non-dividend paying companies further increase the risk of being on the TOL.     

Work and play take school time away? The impact of extracurricular and work time on educational time for live-at-home college students

We use data from the 2003–2014 American Time Use Survey to estimate the effects of time allocated to work and extracurriculars on time spent in educational activities (class and homework) for live-at-home college students, who make up a large share of the college population. Our instrumental variables strategy indicates that students are more likely to substitute time away from homework than from class, and that the effects are generally stronger for work than for extracurriculars. These findings, which remain even after correcting for selection on unobservables through non-parametric matching methods, show that work leads to decreases in the amount of time spent in class by 47 min and on homework by 56 min, whereas extracurriculars lead to a loss of 22 min of homework time. Thus, while after-school activities (extracurriculars and work) may be beneficial with respect to human capital development, they may also have a counteracting, unintended effect due to students’ substitution away from educational pursuits.     

Corruption: what are the effects on government effectiveness? Empirical evidence considering developed and developing countries

This study analyses the impact of corruption on government effectiveness for a sample of 130 countries. The findings suggest that less-corrupt countries have better quality of public service, better quality in the formulation and adoption of policies and greater credibility and government's commitment to such policies. The findings also suggest that the effect of corruption on government effectiveness is higher in developed countries. Moreover, the estimates also reveal that countries with the most indebted governments and with higher inflation rates have less-efficient governments, and an increase in rule of law represents a good strategy to improve government effectiveness. In turn, regarding developing countries, the findings show that countries with more democratic regimes have a higher degree of government effectiveness.     

The effects of education on spouses’ satisfaction in Europe

This article identifies the effects of both own and spouses' education levels on individual economic satisfaction for European households. To that end, it estimates several specifications based on the family collective approach, for each of the 14 EU countries, by using the eight waves of the European Community Household Panel, 1994–2001. After demonstrating that the IV Hausman–Taylor procedure is the selected estimation method in the majority of cases, the empirical results show that male and female income satisfaction significantly increases when the husband achieves higher education qualifications in the majority of European countries. However, the positive effect of the wife's higher education on female income satisfaction only appears in a very limited number of countries. Additionally, increases in individual wage and nonwage incomes generally lead to higher satisfaction levels.     

Input–output evidence on the relative price effects of total productivity shift

This paper provides empirical evidence on the relative price effects of a notional shift in total productivity using data from ten Symmetric Input–Output Tables of five European economies. The results suggest that the direction of the price-movements is, more often than not, governed by the (traditional) labour cost condition and this could be connected to the effective ranks of the matrices of the relative shares of the capital goods.
