We construct a Gause-type predator-prey model with concave prey isocline and (at least) two limit cycles. This serves as a counter-example to the global stability criterion of Hsu [Math. Biosci. 39:1-10 (1978)].

In this work, I construct an extended model of the Heckscher-Ohlin model, in which there is an assignment problem of how to assign workers to two types of endowments, skilled and unskilled labor. In the comparative statics for a small open economy, when product prices change, the outputs change more than in the HeckscherOhlin model. In the comparative statics for a whole economy, when consumer ...

The Heckscher-Ohlin model with arbitrary number of goods, factors and countries (consumers) and no restrictions on factor trading is shown to be equivalent to an exchange model whose goods are the productive factors while consumer’s indirect demands for factors are derived from their actual demands for consumption goods. This equivalence enables one to import properties like the pathconnectedne...
