We provide a graphical illustration of how standard consumer and producer theory can be used to quantify the welfare loss associated with inefficient pricing in insurance markets with selection. We then show how this welfare loss can be estimated empirically using identifying variation in the price of insurance. Such variation, together with quantity data, allows us to estimate the demand for i...

We address the problem of visualizing multivariate correlations in parallel coordinates. We focus on multivariate correlation in the form of linear relationships between multiple variables. Traditional parallel coordinates are well prepared to show negative correlations between two attributes by distinct visual patterns. However, it is difficult to recognize positive correlations in parallel co...

Brazil is the largest Coffea arabica L. producer and exporter in world market. In view of need for nitrogen fertilization, objective this work was to evaluate use digital images coffee leaves as a function concentration cultivars, well most adequate sampling technique predict leaf nitrogen. The experiment set greenhouse, at UNESP - Experimental Campus Registro-SP, using 12L pots with medium san...

User’s choices of conical picks currently involve specifying their material and geometric parameters (functional requirements), incorporating the place conditions work (operational requirements). The selection is usually made based on solely one criterion, which price. Thus, at stage both purchase operation, quality picks, as well matching for a specific machine, are not assessed. problem defin...

It is always attempted to reduce the costs of comminution in mineral processing plants. One of thedifficulties in size reduction section is not to be designed properly. The key factor to design size reductionunits such as crushers and grinding mills, is ore’s work index. The work index, wi, presents the oregrindability, and is used in Bond formula to calculate the required energy. Bond has defi...

sarcheshmeh copper complex is the largest producer of copper in iran. with copper production, high amounts of so2 are being produced in this complex and emmited into the environment. so, in this study, the social optimum level of so2 released from this complex and the optimal tax rate will be evaluated. for this purpose, md and mac curves were estimated. the wtp for the reduction of so2 emissio...
