Optimal Capital Income Taxation with Tax Evasion

The paper discusses the applicability of optimal taxation theory to source-based capital incomes when significant tax evasion is observed. Without tax evasion a modified Ramsey Rule may reduce distortions brought by international capital mobility, leading to levying differentiated tax rates in domestic sectors inversely proportioned to observed elasticities in terms of capital mobility. The introduction of tax evasion brings additional complexity. The viability of optimal tax rates à la Ramsey is explored, and additional requirement (namely that tax evasion is either very low or very homogeneous) are shown to be necessary in order to allow policy-makers to obtain the tax rates minimizing total excess burden. Results are also provided to solve the optimal taxation objective when tax evasion is a relevant phenomenon and is not homogeneous throughout domestic sectors

Effects of deficit irrigation using saline water on 'chenopodium quinoa willd.' Grown in a mediterranean environment

Chenopodium quinoa Willd. is an Andean species that shows a good adaptability to different environmental conditions. A field trial was carried out in 2009 at the CNR-ISAFoM research station to evaluate the response of quinoa under combined stresses of salinity and water shortage. Three irrigation treatments were compared 100, 50, and 25% of the water necessary to replenish to field capacity the soil layer explored by roots. Each treatment was irrigated with saline (ECw 20 dS m-1) and nonsaline water. Standing up to the high expectations, quinoa confirmed the resistance to salinity and water deficit and yield was not significantly different for both water and saline. Similar results were found also for plant water status parameters. © ISHS
