Production externality and productivity of labor.

In this paper we consider two imperfectly competitive industries, with the polluting emissions from one industry harming the productivity of labor in the other. The polluting industry has to pay an environmental tax chosen by the government. In this framework, we analyze how the different organizational structure adopted by workers affect the environmental tax set by the government, total pollution emissions from the polluting industry and the productivity of workers in the industry that suffers the externality. We obtain that this depends on the degree to which pollution emissions from the polluting industry affects the marginal product of labor in the other industry.Production externality, productivity of labor, environmental taxes, imperfect competition, unionized labor.

Strategic Delegation and Semipublic Firms

By considering a mixed oligopoly and considering that public firms are less efficient than private firms, White (2001) shows that if private firms hire managers then the public firm does not do so. We show in this paper that if we consider that a private firm competes with a firm that is owned jointly by both the private and public sectors (a semipublic firm) and that all the firms are equally efficient, then in equilibrium both firms hire managers.Mixed duopoly, Semipublic Firms, Managerial incentive contracts, Cournot competition

Cost-saving production technologies and partial ownership

This work analyzes the incentives to acquire cost-saving production technologies when cross-participation exists at ownership level. We show that cross-participation reduces the incentives to adopt the cost-saving production technology.

Endogenous Timing in a Mixed Duopoly: Wighted Welfare and Price Competition

In this paper we analyse the endogenous order of moves in a mixed duopoly for differentiated goods. Firms choose whether to set prices sequentially or simultaneously. The private firm maximises profits while the public firm maximises the weighted sum of the consumer and producer surpluses (wighted welfare). It is shown that the result obtained in equilibrium depends crucially on the weigth given to the consumer surplus in weighted welfare and on the degree to which goods are substitutes or complements. We also anlyse whether the equilibria obtained maximise the sum of the consumer and producer suspluses or not. Finally we study whether the nationality of the private firm influences the results.mixed duopoly, price competition, endogenous timing, weighted welfare

Empowerment of Indigenous Women and Social Exclusion in Combating Poverty in the State of Veracruz Mexico

In Mexico, the Productive Organization Program for Indigenous Women (POPMI) seeks the empowerment of productive capacities in indigenous women. Our study analyzes POPMI outreach, focusing our attention on women beneficiaries who present a high degree of social exclusion and multidimensional poverty in the State of Veracruz. In the study area, the 542 indigenous women benefited in POPMI, presented a condition of multidimensional poverty and a degree of social exclusion: very high, high and medium, they represent only 22.19% of the total beneficiaries of this program In 2010, since at the state level a total of 2,243 indigenous women were cared for. The results show that the localities where the condition of multidimensional poverty and very high, medium and high levels of social exclusion have been excluded in the coverage of POPMI

Tungsten and the Vestiges of Colonialism in Peru

El artículo propone una reflexión frente a las diversas expresiones del colonialismo que se manifiestan en El tungsteno, la novela social de Vallejo, destacando su plano político y estable­ciendo un paralelo con el pensamiento crítico de Aimé Césaire. Se busca de­mostrar que la iniciativa de reivindicar al mundo indígena desde el marxismo-leninismo constituye, en últimas, una variable más del colonialismoThis article proposes a reflection before different expressions of Colonialism, which are shown in Tungsten, Vallejo’s social novel, highlighting its political plane and setting up a parallel with Aimé Césaire’s critical thinking. It searches for demons­trating that the initiative of defending the indigenous world from Marxist-Lenin theories constitutes one more variable of colonialism
