The overexpression of fdm, which encodes the formaldehyde dismutase from Pseudomonas putida F61, resulted in the formation of inclusion bodies made up of aggregated enzyme, leaving little activity in the soluble fraction of the transformant cells. On the other hand, coexpression of groESL along with fdm facilitated in vivo solubilization of the enzyme protein in its active form. When coexpresse...

We compare the rationality of choice under risk – utility maximization, stochastic dominance, and expected-utility maximization – of students from one of the best universities in the US and one of the best universities in Africa. The US subjects came nearer to consistency with utility maximization and the dominance principle, but there are no differences between the two samples in consistency w...

In this paper the heterogeneous firms and trade literature is extended by integrating quality of inputs and outputs in a food and agricultural setting, along with an analysis of how the ability to translate capability into higher product quality is critical in evaluating the cut-offs for food processing firms to enter domestic and export markets. Specifically, it is found that the direction of ...

Two groups of seller firms—local sellers and foreign sellers—may face different degrees of search frictions even though they are identical in terms of productivity. Two groups of buyer firms are considered: one group accepts local and foreign sellers equally,...
