The Economics of Reducing the County Road System: Three Case Studies in Iowa, HR-242, 1986

This research project looked at the economic benefits and costs associated with alternative strategies for abandoning low volume rural highways and bridges. Three test counties in Iowa were studied, each 100 square miles in size: Hamilton County having a high agricultural tax base and a high percentage of paved roads and few bridges; Shelby County having a relatively low agricultural tax base, hilly terrain and a low percentage of paved road and many bridges; and Linn County having a high agricultural tax base, a high percentage of paved roads and a large number of non-farm households. A questionnaire survey was undertaken to develop estimates of farm and household travel patterns. Benefits and costs associated with the abandonment of various segments of rural highway and bridge mileages in each county were calculated. "Benefits" calculated were reduced future reconstruction and maintenance costs, whereas "costs" were the added cost of travel resulting from the reduced mileage. Some of the findings suggest limited cost savings from abandonment of county roads with no property access in areas with large non-farm rural population; relatively high cost savings from the abandonment of roads with no property access in areas with small rural population; and the largest savings from the conversion of public dead-end gravel roads with property or residence accesses to private drives.

Treatment of genital mycoplasma in colonized pregnant women in late pregnancy is associated with a lower rate of premature labour and neonatal complications.

Mycoplasma hominis and Ureaplasma spp. may colonize the human genital tract and have been associated with adverse pregnancy outcomes such as preterm labour and preterm premature rupture of membranes. However, as these bacteria can reside in the normal vaginal flora, there are controversies regarding their true role during pregnancy and so the need to treat these organisms. We therefore conducted a retrospective analysis to evaluate the treatment of genital mycoplasma in 5377 pregnant patients showing symptoms of potential obstetric complications at 25-37 weeks of gestation. Women presenting with symptoms were routinely screened by culture for the presence of these bacteria and treated with clindamycin when positive. Compared with uninfected untreated patients, women treated for genital mycoplasma demonstrated lower rates of premature labour. Indeed preterm birth rates were, respectively, 40.9% and 37.7% in women colonized with Ureaplasma spp. and M. hominis, compared with 44.1% in uncolonized women (Ureaplasma spp., p 0.024; M. hominis, p 0.001). Moreover, a reduction of neonatal complications rates was observed, with 10.9% of newborns developing respiratory diseases in case of Ureaplasma spp. colonization and 5.9% in the presence of M. hominis, compared with 12.8% in the absence of those bacteria (Ureaplasma spp., p 0.050; M. hominis, p <0.001). Microbiological screening of Ureaplasma spp. and/or M. hominis and pre-emptive antibiotic therapy of symptomatic pregnant women in late pregnancy might represent a beneficial strategy to reduce premature labour and neonatal complications.

Estudio sobre los procesos de integración laboral de los inmigrantes. Study of immigrants' labour integration process

El presente trabajo pretende mostrar los resultados de un estudio cuya intención era identificar posibles variables que afectan a los procesos y estrategias de integración laboral de personas procedentes de otros países; las necesidades formativas en relación al colectivo de referencia y ampliar el conocimiento del fenómeno en aras de la intervención psicoeducativa y social. A partir de una metodología de investigación de orientación cualitativa se ha concluido que las diferencias en cuanto a las estrategias de integración y sus logros están más determinadas por los niveles de cualificación en el país de origen que por las propias diferencias culturales. The article shows the results of a study carried out by the authors to identify possible variables that affect the processes and strategies of occupational integration of people coming from other countries, to establish training needs in relation to the reference group and to extend the knowledge of the phenomenon for the sake of the educational and social intervention. Using a qualitative research methodology, it was concluded that the differences in integration strategies and their accomplishments are better explained by the levels of qualification attained in the country of origin than by cultural differences.

¿Y después del trabajo, qué? Más allá de la integración laboral de las personas con discapacidad = What happens after work? Going further than labour integration for disabled people

La actividad profesional es fundamental en la vida de cualquier persona y en el caso de las que padecen una discapacidad tiene una gran importancia para contribuir a configurar su identidad adulta. En este sentido, la finalidad del artículo es valorar la importancia del trabajo en los procesos de participación social y de calidad de vida de las personas con discapacidad. Por ello, en el artículo se pone de manifiesto la relación que se establece entre la dimensión laboral y la integración social de los individuos con discapacidad mediante el análisis de investigaciones desarrolladas en nuestro contexto, entre las que figuran diversos estudios realizados por nuestro grupo de investigación durante los últimos años. Con la voluntad de conocer con más detalle esta cuestión, se presenta una investigación reciente realizada por nuestro equipo. En ella desarrollamos un estudio de casos centrado en personas con discapacidad psíquica que han participado en experiencias de integración laboral en el mercado ordinario, con el objetivo de obtener información sobre la incidencia de la inserción laboral en diferentes dimensiones de la vida de los trabajadores con discapacidad. Los resultados nos permiten valorar que la experiencia genera cambios positivos, sobre todo a nivel personal (expectativas personales, potenciación del proyecto de vida, mejora de competencias…). Sin embargo, a pesar de que se aprecian mejoras en la dimensión social, el estudio plantea la necesidad de emprender acciones alternativas para potenciar la participación comunitaria de las personas implicadas en la investigación. El artículo concluye con algunas propuestas orientadas a mejorar los procesos de inserción social del colectivo

Construcción de un índice de calidad ocupacional (ICO) para el análisis de la inserción profesional de los graduados universitarios = Building an employment quality index (EQI) to analyse graduates’ access to the labour market

En este trabajo se propone la construcción de un índice de calidad ocupacional (ICO) a partir de los datos de la Encuesta de Inserción Laboral de los Graduados de las Universidades Catalanas realizada por la Agencia para la Calidad del Sistema Universitario de Catalunya (AQU), que ha de permitir un mejor análisis de la información que proporciona la encuesta y facilitar su comparación con estudios similares. La encuesta se realiza tres años después de la graduación. En este artículo, se utiliza la segunda encuesta realizada el año 2005 entre 11.456 graduados (52,63%) de la promoción 2001 (AQU, 2005, Serra-Ramoneda, 2007). El índice se ha elaborado a partir de los indicadores objetivos ‘tipo y duración del contrato laboral’, ‘retribución económica’, ‘adecuación entre la formación universitaria y el empleo’ a los que se otorga una puntuación ponderada según las respuestas dadas por los graduados. La suma de las puntuaciones se matiza con un coeficiente derivado del indicador subjetivo ‘satisfacción con el trabajo en general’. A partir de la información proporcionada por el índice, se realiza un análisis comparativo del nivel de calidad ocupacional que han logrado los graduados de áreas de conocimiento, ámbitos de trabajo, ramas de actividad y ubicaciones territoriales del empleo diferentes. Los resultados obtenidos permiten observar que entre los graduados catalanes los siguientes hechos son buenos predictores de la calidad de la ocupación: haber estudiado una carrera que no sea de Humanidades, ser un hombre, haber desempeñado durante la carrera un trabajo relacionado con los estudios, estar ocupado en la construcción, en instituciones financieras o en servicios a empresas, haber tenido algún tipo de movilidad por motivos de trabajo, trabajar fuera de Cataluña y hacerlo en empresas grandes, especialmente con más de 500 trabajadores. Finalmente, se presentan algunas reflexiones y propuestas que pueden resultar de interés para la orientación de los estudiantes y la planificación universitaria

Saving lives: Evidence from a conditional food supplementation program

Many governments in developing countries implement programs that aim to address nutrionalfailures in early childhood, yet evidence on the effectiveness of these interventions is scant. Thispaper evaluates the impact of a conditional food supplementation program on child mortality inEcuador. The Programa de Alimentaci?n y Nutrici?n Nacional (PANN) 2000 was implementedby regular staff at local public health posts and consisted of offering a free micronutrient-fortifiedfood, Mi Papilla, for children aged 6 to 24 months in exchange for routine health check-ups forthe children. Our regression discontinuity design exploits the fact that at its inception, the PANN2000 was running for about 8 months only in the poorest communities (parroquias) of certainprovinces. Our main result is that the presence of the program reduced child mortality in cohortswith 8 months of differential exposure from a level of about 2.5 percent by 1 to 1.5 percentagepoints.

The effect of tax enforcement on tax elasticities: Evidence from charitable contributions in France

Optimal tax formulas expressed in "sufficient statistics" are usually calibrated under the assumptionthat the relevant tax elasticities are unaffected by other available policy instruments.In practice though, tax authorities have many more instruments than the mere tax rates andtax elasticities are functions of all these policy instruments. In this paper we provide evidencethat tax elasticities are extremely sensitive to a particular policy instrument: the level of taxenforcement. We exploit a natural experiment that took place in France in 1983, when the taxadministration tightened the requirements to claim charitable deductions. The reform led to asubstantial drop in the amount of contributions reported to the administration, which can becredibly attributed to overreporting of charitable contributions before the reform, rather thanto a real change in giving behaviours. We show that the reform was also associated with asubstantial decline in the absolute value of the elasticity of reported contributions. This findingallows us to partially identify the elasticity of overreporting contributions, which is shown tobe large and inferior to -2 in the lax enforcement regime. We further show using bunching oftaxpayers at kink-points of the tax schedule that the elasticity of taxable income also experienceda significant decline after the reform. Our results suggest that optimizing the tax rate fora given tax elasticity when other policy instruments are not optimized can lead to misleadingconclusions when tax authorities have another instrument that could set the tax elasticity itselfat its optimal level as in Kopczuk and Slemrod [2002].

On the impact of microcredit: Evidence from a randomized intervention in rural Ethiopia

We use data from a randomized controlled trial conducted in 2003-2006 in rural Amhara andOromiya (Ethiopia) to study the impacts of the introduction of microfinance in treated communities. We document that borrowing increased substantially in locations where the programs started their operations, but we find mixed evidence of improvements in a number ofsocio-economic outcomes, including income from agriculture, animal husbandry, non-farm self-employment, schooling and indicators of women's empowerment.

The economics of infertility

Infertility is a growing issue that affects thousands of Spanish couples; increasingly there are more and more people who cannot raise a family by themselves. Instead they have to resort to ART, adoption -local or international- or surrogacy abroad, a practice that many couples consider but that isn’t legalized in Spain. In this paper we have broken down each option in detail by analysing the market, differentiating its variants and specific steps, calculating its “price” and suggesting possible improvements that could be made from an economic perspective. We end our paper with the “SWOT” analysis of a hypothetical surrogacy market in Spain by calculating an estimated price, using the US as a reference, and the degree of acceptance it would have, based on the results of random surveys.
