Accessibility and affordability of tertiary education in Brazil, Colombia, Mexico and Peru within a global context

This paper examines the financing of tertiary education in Brazil, Colombia, Mexico and Peru, comparing the affordability and accessibility of tertiary education with that in high-income countries. To measure affordability, the authors estimate education costs, living costs, grants, and loans. Further, they compute the participation rate, attainment rate, and socio-economic equity index in education and the gender equity index as indicators of accessibility. This is the first study attempting to estimate affordability of tertiary education in Latin America within a global context. The analysis combines information from household surveys, expenditure surveys, and administrative and institutional databases. The findings show that families in Latin America have to pay 60 percent of per-capita income for tertiary education per student per year compared with 19 percent in high-income countries. Living costs are significant, at 29 percent of gross domestic product per capita in Latin America (19 percent in high-income countries). Student assistance through grants and loans plays a marginal role in improving affordability. Moreover, the paper confirms previous findings of low access to tertiary education in the region. One policy implication of the findings is that Latin American governments could take steps to make tertiary education more affordable through student assistance.Tertiary Education,,Access&Equity in Basic Education,Access to Finance,Teaching and Learning

Can student loans improve accessibility to higher education and student performance? An impact study of the case of SOFES, Mexico

Financial aid to students in tertiary education can contribute to human capital accumulation through two channels: increased enrollment and improved student performance. We analyze the quantitative importance of both channels in the context of a student loan program (SOFES) implemented at private universities in Mexico. With regard to the first channel, enrollment, results from the Mexican household survey indicate that financial support has a strong positive effect on university enrollment. Given completion of upper secondary education, the probability of entering higher education rises 24 percent. Two data sourcesare used to investigate the second channel, student performance. Administrative data provided by SOFES are analyzed using a regression-discontinuity design, and survey data enable us to perform a similar analysis using a different control group. Empirical results suggest that SOFES recipients show better academic performance than students without a credit from SOFES. However, the results cannot be interpreted as a purely causal impact of the student loan program, since the impacts also could reflect (self-) selection of students.Primary Education,Public Health Promotion,Health Monitoring&Evaluation,Teaching and Learning,Environmental Economics&Policies,Health Monitoring&Evaluation,Primary Education,Environmental Economics&Policies,Teaching and Learning,Gender and Education

Progress in Participation in Tertiary Education in India from 1983 to 2004

Using nationally representative household surveys, this paper examines the trends in attainment, enrollment, and access to tertiary (higher) education in India from 1983 to 2005. The findings suggest that there has been considerable progress in attainment and participation; however, they remain low. Important gaps exist in enrollment between rich and poor, rural and urban areas, men and women, disadvantaged groups and the general population, and states. Analysis of transition rates from secondary education to tertiary education and regression analysis indicate that inequality in tertiary education between disadvantaged groups and the general population is explained by low completion rates of secondary education. Inequality in tertiary education related to income, gender, rural residence, and between states is explained by: (i) differences in completion rates of secondary education, and (ii) differences in the probability of transitioning from secondary education to tertiary education. In particular, the importance of household income has grown markedly. Equitable expansion of secondary education is therefore critical for improving the equity of tertiary education. There is also a need to help qualified youth from low-income families and rural backgrounds to attend tertiary education, in particular the technical and engineering streams, in which participation is lower.access to higher education; access to tertiary education; age cohort; age group; age groups; colleges; competition for entry; completion rate; completion rates degree courses; degrees

Education, earnings, and inequality in Brazil, 1982-98 - implications for education policy

The educational attainment of Brazil's labor force, has gradually increased over the past two decades. At the same time, the government has pursued a series of economic structural adjustment policies. The authors investigate how these simultaneous advances have altered the relationship between labor market earnings, and education. They find that the returns to education in the labor market, fundamentally changed between 1982, and 1998. While the returns to tertiary education increased sharply, the returns to primary education dropped by 26 percent, and those to lower secondary, by 35 percent. Moreover, the authors argue, the marginal reduction in wage inequality that occurred in this period was linked primarily to a reduction in the returns to schooling, and only secondarily, to a more equitable distribution of schooling. The findings suggest that the supply of highly skilled labor is inadequate to meet demand. That suggests a need for policy action aimed at increasing access to, and completion of tertiary education. Increasing the supply of highly skilled labor, would improve prospects for both economic growth, and reduce wage inequality.Public Health Promotion,Curriculum&Instruction,Decentralization,Teaching and Learning,Health Monitoring&Evaluation,Teaching and Learning,Curriculum&Instruction,Gender and Education,Health Monitoring&Evaluation,Girls Education

Trade liberalization and labor market adjustment in Brazil

The authors study the impact of the 1988-94 trade liberalization in Brazil on wage distribution. They explore three main channels through which trade liberalization could have affected wage distribution: (1) increasing returns to skilled workers because of Hecksher-Ohlin adjustments to trade policy; (2) trade-induced skill-biased technological change; and (3) changes in industry wage premiums. The results suggest that trade reform inBrazil did contribute to the growing skill premium through skill-biased technological change, which was partially instigated by increased foreign competition. The authors also find that sector-specific returns to skill increased more in sectors with bigger tariff reductions. But they find little support for Hecksher-Ohlin type adjustments to trade reform. Overall, the effects of trade reform on wage inequality seem relatively small.Water and Industry,Municipal Financial Management,Health Monitoring&Evaluation,Environmental Economics&Policies,Public Health Promotion,Municipal Financial Management,Health Monitoring&Evaluation,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT,Environmental Economics&Policies,Water and Industry

Human capital and university-industry linkages'role in fostering firm innovation : an empirical study of Chile and Colombia

A firm's absorptive capacity, human capital and linkages with knowledge institutions have been shown to increase the firm's probability of innovating in OECD economies. Despite its importance for national- and firm-level competitiveness, few papers examine the impact of the same variables for firms innovation in Latin America. This paper investigates the link between firm innovation and its absorption capacity as proxied by the presence of a R&D department, the firm's human capital, and its interaction with research centers and universities. We analyze the case of Chilean and Colombian manufacturing firms using data from innovation surveys. A probit regression model is applied to identify the determinants of innovation activity. We find that collaboration with university and research institutions is associated with an increase in the probability of introducing a new product in Chilean and Colombian firms of 29 and 44 percent, respectively, and it can increase up to 58 percent in the case of Colombian firms interacting with research centers. Moreover, firms whose employees have a higher level of education, or whose managers/supervisors have a higher (perceived) level of knowledge, are more likely to innovate. Although the estimates could be affected by biases and suffer from shortcomings in data, the findings suggest that policies and incentives to increase firm-level human capital and industry-university linkages are important to increase innovation in Latin America.E-Business,Education for Development (superceded),Innovation,Agricultural Knowledge&Information Systems,Labor Policies

Synthetic inversions for density using seismic and gravity data

Density variations drive mass transport in the Earth from plate tectonics to convection in the mantle and core. Nevertheless, density remains poorly known because most geophysical measurements used to probe the Earth's interior either have little sensitivity to density, suffer from trade-offs or from non-uniqueness. With the ongoing expansion of computational power, it has become possible to accurately model complete seismic wavefields in a 3-D heterogeneous Earth, and to develop waveform inversion techniques that account for complicated wavefield effects. This may help to improve resolution of density. Here, we present a pilot study where we explore the extent to which waveform inversion may be used to better recover density as a separate, independent parameter. We perform numerical simulations in 2-D to investigate under which conditions, and to what extent density anomalies may be recovered in the Earth's mantle. We conclude that density can indeed be constrained by seismic waveforms, mainly as a result of scattering effects at density contrasts. As a consequence, the low-frequency part of the wavefield is the most important for constraining the actual extent of anomalies. While the impact of density heterogeneities on the wavefield is small compared to the effects of velocity variations, it is likely to be detectable in modern regional- to global-scale measurements. We also conclude that the use of gravity data as additional information does not help to further improve the recovery of density anomalies unless strong a priori constraints on the geometry of density variations are applied. This is a result of the inherent physical non-uniqueness of potential-field inverse problems. Finally, in the limited numerical setup that we employ, we find that the initially supplied anomalies in S- and P-velocity models are of minor importance

The imprint of crustal density heterogeneities on regional seismic wave propagation

Density heterogeneities are the source of mass transport in the Earth. However, the 3-D density structure remains poorly constrained because travel times of seismic waves are only weakly sensitive to density. Inspired by recent developments in seismic waveform tomography, we investigate whether the visibility of 3-D density heterogeneities may be improved by inverting not only travel times of specific seismic phases but complete seismograms. As a first step in this direction, we perform numerical experiments to estimate the effect of 3-D crustal density heterogeneities on regional seismic wave propagation. While a finite number of numerical experiments may not capture the full range of possible scenarios, our results still indicate that realistic crustal density variations may lead to travel-time shifts of up to  ∼ 1 s and amplitude variations of several tens of percent over propagation distances of  ∼ 1000 km. Both amplitude and travel-time variations increase with increasing epicentral distance and increasing medium complexity, i.e. decreasing correlation length of the heterogeneities. They are practically negligible when the correlation length of the heterogeneities is much larger than the wavelength. However, when the correlation length approaches the wavelength, density-induced waveform perturbations become prominent. Recent regional-scale full-waveform inversions that resolve structure at the scale of a wavelength already reach this regime. Our numerical experiments suggest that waveform perturbations induced by realistic crustal density variations can be observed in high-quality regional seismic data. While density-induced travel-time differences will often be small, amplitude variations exceeding ±10 % are comparable to those induced by 3-D velocity structure and attenuation. While these results certainly encourage more research on the development of 3-D density tomography, they also suggest that current full-waveform inversions that use amplitude information may be biased due to the neglect of 3-D variations in density

The spectrum of skin‐related conditions in primary care during 2015–2019–A Finnish nationwide database study

Background: Skin‐related conditions are the frequent cause of doctors’ consultations in primary care. Methods: Based on nationwide data bank information of the Finnish Institute for Health and Welfare, we analysed the 20 most frequent main diagnoses for each ICD‐10 category of all general practitioners’ visits in the public health care in Finland over the years 2015–2019. Results: The total amount of doctor’s visits was 19 204 613 of which 1 489 228 consultations (7.80%) had a skin‐related condition as the main diagnosis. The most frequent skin‐related conditions were eczematous eruptions, bacterial skin infections and benign skin neoplasms accounting for 749 351 consultations (50.32%). The spectrum of skin‐related conditions was diverse, with a large quantity of rarer diagnoses. Some diagnoses showed significant proportional changes. Conclusions: The results demonstrate that a limited amount of conditions comprises most of the skin‐related consultations in primary care in Finland. Undergraduate education in dermatology should concentrate on the most frequent conditions seen by general practitioners, but also address the wide range of skin problems.Peer reviewe

Seismic waveform tomography of the central and eastern Mediterranean upper mantle

We present a seismic waveform tomography of the upper mantle beneath the central and eastern Mediterranean down to the mantle transition zone. Our methodology incorporates in a consistent manner the information from body and multimode surface waves, source effects, frequency dependence, wavefront healing, anisotropy and attenuation. This allows us to jointly image multiple parameters of the crust and upper mantle. Based on the data from ∼ 17 000 unique source–receiver pairs, gathered from 80 earthquakes, we image radially anisotropic S velocity, P velocity and density. We use a multi-scale approach in which the longest periods (100–150 s) are inverted first, broadening to a period band of 28–150 s. Thanks to a strategy that combines long-period signals and a separation of body and surface wave signals, we are able to image down to the mantle transition zone in most of the model domain. Our model shows considerable detail in especially the northern part of the domain, where data coverage is very dense, and displays a number of clear and coherent high-velocity structures across the domain that can be linked to episodes of current and past subduction. These include the Hellenic subduction zone, the Cyprus subduction zone and high-velocity anomalies beneath the Italian peninsula and the Dinarides. This model is able to explain data from new events that were not included in the inversion
