In a directed search model, we allow the unemployed and the vacancies to choose whether to send or receive wage offers. This determines the market structure. There are several equilibria but a unique evolutionary stable one. Wage offers are made under incomplete information about the number of...

We consider an economy with symmetric buyers and symmetric sellers. Sellers are in locations and post prices, and buyers observe the prices and visit one location per period. If there are several sellers in a location, a uniform price is not a Nash equilibrium. We derive a pricing scheme with a...

We consider an economy with symmetric buyers and symmetric sellers. The sellers are in locations and post prices simultaneously. The buyers observe the prices, and each buyer visits one location. The buyers act independently and employ symmetric mixed strategies. We show that when there are...

We consider a standard search model with buyers and sellers. Upon meeting the buyers make a take-it-or-leave-it offer, but the sellers have an option not to trade immediately but wait for more agents to appear. If more buyers come, there is excess demand, and the buyers engage in auction to get...

Emissions trading in climate change can entail large overall cost savings and transfers between developed and developing countries. However, the search for acceptable JI or CDM projects implies a deviation from the perfect market framework used in previous estimations. Our model combines the...

The market mechanisms built into the Kyoto Protocol have the potential of significantly reducing costs of limiting greenhouse gases. But if trading proceeds on a bilateral project-by-project basis rather than on a frictionless market, the total cost saving potential of trading is unclear. This...
