This paper provides the theoretical explanation and Monte Carlo experiments of using a modified version of Durbin-Watson ( D W ) statistic to test an 1 ( 1 ) process against I ( d ) alternatives, that is, integrated process of order d, where d is a fractional number. We provide the exact order...

This paper is concerned with the determination of the optimal time horizon for the cake-eating problem under uncertainty. It is shown that if the uncertain exhaustible resource stock is a discrete random variable admitting at most a finite number of values, the optimal planning horizon is...

We introduce learning into a Hotelling model of a non-renewable resource market. By combining learning and scarcity we add significantly to the dynamics implied by learning and substantially enhance the volatility of commodity prices. In our learning model we show how a self confirming...

Unilateral second-best carbon taxes are analysed in a two-period, two-country model with international trade in final goods, oil and bonds. Acceleration of global warming resulting from a future carbon tax is large if the price elasticities of oil demand are large and that of oil supply is...

This paper shows that a seemingly simple assumption – that agents use a rolling planning horizon – can reconcile the puzzling long run price dynamics of exhaustible resources such as oil, gas and metals. A rolling horizon has the effect of removing the scarcity consideration of resource...

The optimal reaction to a pending productivity shock of which the expected arrival time increases with global warming is to accumulate more precautionary capital to smooth consumption and to levy a carbon tax, proportional to the marginal hazard of a catastrophe, to curb the risk of climate...

Meeting the demand for mineral commodities is crucial for sustainable development and social welfare. Prospecting and exploration in Poland in the second half of 20th century allowed to discover and demonstrate important resources of various minerals. National economic security regarding the...

The petroleum refining industry has changed over the past decades from one in which capacity primarily served local and regional markets to one in which trade in refined petroleum products has become more widespread. We investigate the hypothesis of increasing globalization by examining the...
