This paper develops a continuous-time satiation preference with multiple needs and multiple goods. Goods meet different kinds of needs and the degree to which needs are met determines the utility. We derive closed-form solutions to the optimal consumption problems with a class of tractable...

We investigate the relationship between the gas spot market and the price of gas storage capacity. Contrary to the common belief, the auction prices for gas storage are mostly affected by the volatility of current market prices rather than by the winter-summer price differences. This paper...

Background: In the past couple of years, China's futures exchanges have launched nighttime trading sessions. Methods: We use daily data from 23 commodity futures to investigate the impact of this important policy change. Results: Our findings suggest that the launching of nighttime trading...

We apply utility indifference pricing to solve a contingent claim problem, valuing a connected pair of gas fields where the underlying process is not standard Geometric Brownian motion and the assumption of complete markets is not fulfilled. First, empirical data are often characterized by...

China, the world's largest energy consumer, has been increasingly relying on pricing policies to improve energy efficiency in recent years. This paper estimates the impact of Differential Electricity Pricing (DEP) policy, which covers the most energy-intensive industries in China. Under the DEP...

Present equivalents of future payouts elicited from individuals exhibit a high variability in the underlying discount rate, suggesting that multiple factors influence discounting. One such factor --- shown to be robust --- is the magnitude effect, whereby small future payouts are discounted more...

The standard continuous-time version of discounted utility does not possess the local inter-temporal substitution property (quantities consumed in nearby dates should be close substitutes, not complements), and hence does not define a continuous functional in the space of consumption paths. The...

When a consumer purchases an item, the presumption is that the benefit obtained from it exceeds the price paid—we can think of this difference as the consumer profit. How do consumers calculate this profit, especially when they do not immediately consume the purchased item? This technical note...
