The medical expense deduction and income levels: Progressive or regressive?

The medical expense deduction (MED) allows taxpayers to deduct from taxable income a proportion of their out-of-pocket medical insurance and health care expenses. Because the rate of subsidy is equal to the marginal tax rate previous studies have found MED to be a regressive tax mechanism biased toward benefiting higher-income taxpayers. The authors demonstrate, using GINI coefficients, that MED makes the tax structure more progressive than it would otherwise be and increases equality of after-tax incomes.     

Changes needed in agricultural policy for female-headed farm families in tropical Africa

The decline in per-capita agricultural production has been reversed somewhat in tropical Africa by the structural adjustment programs which have increased producer prices, liberalized marketing and devalued currencies. But the 30% of smallholder farm households which are female-headed will not be assited much due to their special constraints of shortages of labor and credit, lack of extension visits and appropriate labor-saving technologies. For these households, the authors argue, improved extension services, credit for agricultural inputs, small ruminant animals and poultry, labor-saving devices and craft inputs will be necessary to increase their incomes and levels of living.     

AN ANALYSIS OF SUPPLY CHAIN COLLABORATIONS AND THEIR EFFECT ON PERFORMANCE OUTCOMES

This research examined how operational outcomes, relational outcomes and business performance are affected by a collaboration project between buyers and suppliers in a supply chain. It is hypothesized that interdependence of knowledge and process, supply chain partner insight, and the level of collaboration between the firms affect the outcomes of a collaboration project. Survey data from buyers and suppliers from a wide range of industries and organizations were used in this analysis. Among these participants, higher levels of collaboration led to improvements in operational and relational outcomes, which together led to improvements in asset utilization, competitive position, organizational performance, and profitability.     

Russia’s salt industry: Problems of development

The paper describes the current situation in the salt industry. It points to the inadmissibly high and expanding market share of imported salt products despite the country’s own colossal resource base and the domestic enterprises’ huge unused capacities. It has been shown that OAO Russian Railroads (OAO RZhD) will economically benefit due to its reasonable policy of selective reduction of the railroad shipment tariffs for salt for domestic producers due to the inevitable growth of the country’s own salt output.
