We analyze positive theories of redistribution, social insurance and public good provision in a dynamic macroeconomic framework. Political outcomes are determined via repeated voting and driven by a conflict of interests between agents. Voters and politicians rationally forecast the impact of current political choices on future political and economic outcomes. The theory is consistent with larg...

Using an individual panel data set to control for student fixed effects, we estimate the impact of charter schools on students in charter schools and in nearby traditional public schools. We find that students make considerably smaller achievement gains in charter schools than they would have in public schools. The large negative estimates of the effects of attending a charter schools are neith...

It is vividly debated how the ongoing process of European integration will a¤ect the need and scope for welfare state activities. To some this process signals that welfare state activities have to be rolled back, while others stress that international integration may increase the need for (explicit or implicit) social insurance arrangements.

This paper measures the extent to which the presence of religious state-funded secondary schools in England impacts on the educational experiences of pupils who attend neighbouring schools, whether through school effort induced by competition or changes in peer groups induced by sorting. National administrative data is used to estimate pupil test score growth models between the ages of 11 and 1...

It is shown with the help of a voting model that both the proportion of informed voters in a society and the state of the economy matter for determining who ...

OBJECTIVES Invasive pulmonary aspergillosis is associated with high mortality. To assess new antifungal therapy options, animal models have to be developed to assess, in an appropriate setting, the activity of new drugs. METHODS Male albino CD rats (125-150 g) were fed with a protein-free diet and received dexamethasone thrice weekly subcutaneously during the whole experiment. After 2 weeks, ...

The aim of this study was to evaluate and validate the efficiency of 12C6+ irradiation of Aspergillus niger (A. niger) or mutagenesis via mixed Trichoderma viride (T. viride) culturing as well as a liquid cultivation method for cellulase production via mixed Trichoderma reesei (T. reesei) and A. niger culture fermentation. The first mutagenesis approach was employed to optimize yield from a cel...

UNLABELLED The presence of highly pathogenic Shiga-toxin-producing Escherichia coli (STEC) in shellfish, upstream waters and sediment from coastal shellfish sites was evaluated using the ISO/TS-13136 method. Shellfish (oysters, mussels and cockles), water and sediment samples were collected monthly over a period of 1 year. The method used real-time PCR detection of stx1, stx2 and eae genes and ...
