Does trust increase willingness to pay higher taxes to help the needy?

The article studies the causal effect of trust on the willingness to pay higher taxes to help the needy in a sample of 29 countries of Eastern and Southern Europe, and the former Soviet Union and Mongolia. It is hypothesized that interpersonal trust leads to a greater willingness to pay taxes to help the needy since (i) trust increases the likelihood of helping strangers; (ii) trust fosters solidarity and cooperation when working to solve common problems in society; and (iii) trust reduces suspicion with respect to the perceived misuse of redistributed money. Three key findings are that the more people trust each other, the more they are ready to support the welfare state; the effect of trust on welfare state support holds even in a contextual environment characterized by rather lower levels of trust and relatively underdeveloped systems of redistribution; and higher individual‐level trust fosters tax morale and helps deter tax evasion.     

Bringing the owners back in: An analysis of a 3-mode interlock network

This paper examines the association between ownership and director interlocks in Swedish big business during the period 1990–2005. By analyses of the 3-mode network of owners, firms, and directors, multiple director assignments are shown to be highly dependent on owner interlocks. The findings provide a new understanding of the mechanisms behind the formation of director interlocks. Furthermore, the association between the interlock types suggests that the ownership network may potentially (co-)produce some of the phenomena that have been attributed to the director network. Future analyses of director interlocks have to bring the owners back in.

Linking taxation and social protection: Evidence on redistribution and poverty reduction in Ethiopia

Although redistribution results from the simultaneous effects of taxes and transfers, analyses of their distributional effects in low‐income countries have largely been undertaken from singular perspectives. This article jointly assesses the distributional effect of taxes and transfers (through social protection) using Ethiopia as a case study. We find that Ethiopia's flagship social protection programme is more effective than income taxation in achieving poverty reduction, while neither policy achieves a sizeable reduction in overall inequality. We also find that Ethiopia does not currently have the capacity to close the poverty gap or to fully fund its main safety net programme using domestic income sources alone.

Analysis of child labour in Peru and Pakistan: A comparative study

This paper analyses child labour participation and its key determinants using data sets from Peru and Pakistan. The results include tests of the ‘Luxury’ and ‘Substitution’ hypotheses that play key roles in recent studies on child labour and child schooling. The results reject both hypotheses in the context of child labour in Pakistan and suggest that income and related variables do not have the expected negative effect on children's work input. Rising wages of adult female labour in Pakistan, and falling adult male wage in Peru lead to increased participation of children in the labour market. The results on the combined country data formally establish the presence of strong individual country effects in the estimated regressions. For example, ceteris paribus, a Peruvian child is more likely to experience schooling than a Pakistani child. However, both countries agree on the positive role that adult female education and infrastructure investment in basic amenities can play in discouraging child labour and encouraging child schooling.

SrBPO5:Ce3 的光谱特性

运用高温固相法,在空气中合成了SrBPO5:Ce3 荧光体,通过研究SrBPO5:Ce3 的光谱特性,发现激发光谱随Ce3 的掺入量增加而红移,据此认为Ce3 在进入格位时有两种电荷补偿方式,发射光谱则随Ce3 的掺入量增加而增强.
