    Strategies to improve quality and safety and reduce cost of peroduction in organic and low-input crop production systems

    Organic crop production seeks to produce high quality foods while reducing the inputs in order to promote environmental quality and conserve resources. This necessitates optimal production systems in terms of soil fertility and plant health. Studies in QLIF subproject 3 have shown that soils may gain an improved potential to release N from badded amendments through adaptation of management practices. Likewise, long-term management strategies may influence suppressiveness of soils to economically important diseases. Application of manures and other organic soil fertility inputs do not pose any additional safety risk in ready-to-eat vegetables, such as head lettuce, if good farming practice is applied. Even under experimental worst-case conditions, pathogen transfer from soil treated with farmyard manure to vegetables was not substantial. Pest and disease control was studied both at seed and field levels, and it was shown, e.g., that Ăź-amino-butyric acid was efficient in controlling downy mildew in lettuce under field conditions. Finally, for organic wheat production systems, an integrated assessment indicated that yields and protein contents can be increased by improved cultivar choice and fertility management regimes promoting biological N fixation in the soil

    The Effect of Poverty on the Health of Newborn Children – Evidence from Germany

    Get PDF
    This paper analyses the association between health outcomes of newborn children and mother’s poverty status during pregnancy.We use a new questionnaire accompanying the GSOEP which collects abundant information on health outcomes. The findings indicate that there is generally no effect from poverty to health, except on the probability of preterm birth. Furthermore,we find some indication of intergenerational transmission of health status.Poverty, child birth, doctor visits

    System failures in public sector innovation support measures: The case of Estonian innovation system and dairy industry

    Get PDF
    The external and internal context of the firms is influenced by governmental interventions. For a long time the discussion over government interventions to the market processes and economic environment has taken place. It is accepted by different researchers including supporters of social market economy that some interventions are necessary to create general framework for and achieve desirable outcomes of economic processes through laws, regulations etc. There are different approaches discussing whether and how strongly government should intervene. Reasons for and circumstances in what public sector should intervene and weather the intervention itself creates additional failures or not have mainly been rested on two concepts: market and system failures (Edler, Georghiou 2007: 952). --Innovation Molkereiindustrie,Estland

    Does Money Buy Higher Schooling? Evidence from Secondary School Track Choice in Germany

    Get PDF
    The German schooling system selects children into different secondary school tracks already at a very early stage in life. School track choice heavily influences choices and opportunities later in life. It has often been observed that secondary schooling achievements display a strong correlation with parental income.We use sibling fixed effects models and information on a natural experiment in order to analyze whether this correlation is due to a causal effect of income or due to unobservable factors that themselves might be correlated across generations. Our main findings suggest that income has no positive causal effect on school choice and that differences between high- and low-income households are driven by unobserved heterogeneity, e.g. differences in motivation.Child poverty, educational attainment, secondary schools, sibling differences, natural experiment

    The Impact of a Large Parental Leave Benefit Reform on the Timing of Birth around the Day of Implementation

    Get PDF
    The introduction of the German parental leave benefit (Elterngeld) applied to all children born on January 1st, 2007 or later. The new Elterngeld considerably changed the amount of transfers to families during the first two years postpartum. We show that the incentives created by using a cut-off date led more than 1000 parents to postpone the delivery of their children from December 2006 to January 2007. Besides analyzing the timing of delivery the paper focuses on potential adverse health outcomes of children affected by the shift in date of birth.Cut-off date effect, fertility, policy evaluation

    Child Benefit Reform and Labor Market Participation

    Get PDF
    This paper examines the impact of a change in the German child benefit system in 1996, which led to a large increase in lump sum transfers to families with children.We analyze the impact on the labor force participation of family members. Comparing behavioral changes of adults with children with behavioral changes of adults without children,we find that single mothers and mothers with a working partner considerably reduced the number of working hours (conditional on participation). Participation rates however did not decrease. For single fathers neither participation rates nor working hours display any significant changes.Child support, labor supply, program evaluation
