Succeeding Dutta, Sen and Vohra (1995) and Saijo, Tatamitani and Yamato (1995), we define several conditions of natural mechanisms in production economies, and proposed two types of natural mechanisms, that is, the quantity and price-quantity types.

We propose a simple model of competition for the production of energy between a thermal station and an hydrostation. We show analytically and geometrically that, despite its static characteristics, the output from the thermal station is determined by the intertemporal specifications of costs and...

We study the development of an industry-evolution of capacity, production and prices- in a continuous-time real-options model under various assumptions on competition. Investment takes the form of sequential acquisition of indivisible units of capacity. As benchmarks, we determine the optimal...
