one of the unique characteristic of agricultural agreement is to order the countries to accept the commitments in three different areas such as domestic support, market access and export subsidy. although the main goal of this type of classification is the reduction of distortion interventions of trade, but indicates that the agricultural agreement has special attention to political tools again...

Given a multivariate complex polynomial p∈C[z1,…,zn], the imaginary projection I(p) of p is defined as variety V(p) onto its part. We focus on studying polynomials and we state explicit results for certain families them with arbitrarily large degree or dimension. Then, restrict to conic sections give full characterization their projections, which generalizes classification case real conics. Tha...

The paper develops an overlapping generations model that highlights interactions between social security, unemployment and growth.The social security system has two components: old age pensions and unemployment insurance. Pensions have a direct effect on economic growth. Both pensions and unemployment benefits influence equilibrium unemployment caused by wage bargaining. Since unemployment impa...

In this paper we prove that, if p is a boundary point of a smoothly bounded pseudoconvex Reinhardt domain in Cn, then the variety type at p is identical to the regular type. In this paper we study the finite type conditions on pseudoconvex Reinhardt domain. We prove that, if p is a boundary point of a smoothly bounded pseudoconvex Reinhardt domain in C, then the variety type at p is identical t...

conclusions this study showed that hiv-infected patients with jobs enjoy a great deal of acceptance from the people around them and a higher quality of life in general. it also led to suggestions for further study with the purpose of finding more effective solutions for hiv prevention and better strategies for dealing with psychological disorders. such research could also help in providing an e...

Domains of generalized single-peaked preferences are classified in terms of the extent to which they enable well-behaved strategy-proof social choice. Generalizing the Gibbard-Satterthwaite Theorem, we characterize the domains that admit non-dictatorial strategy-proof social choice functions. We also provide characterizations of the domains that enable locally non-dictatorial, anonymous, and ne...

It is known that on some social choice and economic domains, a social choice function is coalition strategy-proof if and only if it is Maskin monotonic (e.g. Muller and Satterthwaite, 1977). This paper studies the foundation of those results. I provide a set of conditions which is sufficient for the equivalence between coalition strategy-proofness and Maskin monotonicity. This generalizes some ...

This paper studies how children learn to bargain. We performed simple anonymous bargaining experiments with real payoffs with 256 children from age 8 to 18. Average offers by even the youngest children were close to the amount that maximized their expected monetary payoff. Furthermore offers and responses were similar to what others have reported for adults. The variance of proposals was higher...

background: availability of antiretroviral therapies has transformed aids into a manageable chronic condition and im­proved well-being among people living with hiv/aids (pha) in developed countries. in developing countries however, such transformations are yet to occur due to socio-economic, systemic and environmental constraint. this study examined the impact of social, economic, psychological...

Cooperating and trusting behavior may be explained with preferences over social outcomes (people care about others, are unselfish and helpful), or attitudes to work and social responsibilities (plans have to be carried out, norms have to be followed). We test the relative importance of these two factors considering personality traits of subjects in experiments with costly mental effort provisio...
