This paper investigates the relationship between trade policy and growth using a dynamic panel regression model with GMM estimates for data on 44 developing countries over 1980-1999. Trade policy is captured by measures of tariffs, import and export taxes. Typically, the average effects of changes in such policy variables have been investigated. However, from a policy perspective, the different...

A number of health state descriptive systems have been specifically designed for calculating a single index value for every state defined within the system. Since most descriptive systems define more health states than it is feasible to elicit direct valuations for in an empirical study, choices have to be made about how best to estimate values for all states from direct observations on a subse...

This study aimed to extend the shelf life of walnut kernels by appropriate packaging conditions and physical methods. For this purpose, the kernels were heated at 50 or 70°C for 2 or 10 minutes. About 100g of walnuts were packed in low-density polyethylene (LDPE) packages under ordinary, vacuum or nitrogen conditions. Samples were stored for 18 months at room temperature. Peroxide value and aci...
