Abstract. In our earlier studies of the supermarket industry in Edmonton, Alberta, we tested for predation in a spatial setting and found evidence which supported the predation hypothesis. In this paper we use data on the locations, entry, exit and market area populations of supermarkets in Edmonton to test whether the entry deterrence and timing-of-expansion implications of the reputation hypothesis are confirmed. We find that our time series data are consistent with entry's being deterred and with delayed opening of new supermarkets by the dominant established firm. [ABSTRACT FROM AUTHOR]

Costs and supply in petroleum exploration: the case of Alberta. A stochastic production function for the discovery of new petroleum reserves is developed which incorporates the following features: the effects of the accumulation of geological knowledge, the effects of the eventual exhaustion of undiscovered reserves, and the tendency for the largest reservoirs to be found early in the development of a region. The associated marginal exploration cost function, which is the quantity of ultimate interest, is derived from the production function in the usual way. The marginal exploration cost function is then estimated for several traditional producing regions in Alberta by estimating the parameters of the production function directly. The empirical results indicate that marginal exploration costs are rising rapidly in these regions. [ABSTRACT FROM AUTHOR]
