This study examined the determinants and impacts of mobile money (MM) usage on maize productivity poverty likelihood (i.e., probability a household falling below international line at USD 1.9 per capita day) in Mbeya Region, Tanzania. The analysis was conducted using endogenous switching regression (ESR) model data from random sample 1310 households selected seven districts region. Results ESR ...

We study social welfare under monopoly using a version of the Kelton and Wallace (1995) two-good general-equilibrium monopoly production model. Individuals are heterogeneous with respect to preferences. They have identical production technologies and labor resources, but only a fraction of them share a monopoly license to produce one of the goods. Numerical evidence indicates that social welfar...

To generate big responses of unemployment to productivity shocks in a business cycle context or to productivity changes in a welfare state context, researchers have reconfigured matching models in various ways, e.g., by elevating the utility of leisure, by making wages sticky, by assuming alternating-offer wage bargaining, by introducing fixed matching costs, and the costly acquisition of credi...

Based on a numerical model where climate change affects productivity, the second-best optimal carbon tax is found to exceed marginal social damage by 53 percent, and " marginal private damage " (aggregate households' marginal willingness to pay) by 73 percent. Annual welfare gains from carbon taxation are estimated at $3.58 billion when marginal damage is $40 per ton; employment also increases....

During transition, maintaining employment and providing a social safety net to the unemployed are important to social stability, which in turn is crucial for the productivity of the whole economy. Because independent institutions for social safety are lacking and firms with strong profit incentives have little incentives to promote social stability due to its public good nature, state-owned ent...

In standardWalrasian macro-finance models, pecuniary externalities such as fire sales lead to overinvestment in illiquid assets or underprovision of liquidity. We investigate whether imperfect competition (Cournot) improves welfare through internalizing the externality and find that this is far from guaranteed. In a standard model of liquidity shocks, when liquidity is sufficiently scarce, Cour...

The release of the Final Guidance from the US Food and Drug Administration on the commercialization of genetically engineered animals has sparked renewed discussion over the ethical, consumer, and regulatory implications of transgenesis in animal agriculture. Animal welfare critiques have focused on unexpected phenotypic effects in animals used in transgenic research, rather than on the health ...

In this paper, the impact of alternative development strategies on growth and poverty is assessed in an economywide framework, using Egypt as a case study. The analysis is guided by the following question: By pursuing a development strategy different from the one actually pursued since the late 1970s, could Egypt’s government significantly have improved the status of its poor? To address this q...

This review examines the behaviour and productivity of the water buffalo (Bubalus bubalis) under different breeding systems and in relation to meat and milk production. At present, the steady increment in the consumption of products and sub-products of this species has generated the need to increase the number of animals incorporated into production by progressively expanding the use of stablin...
