A risk-neutral agent optimizes extraction of dividends or renewable natural resources modelled by a jump-diffusion stock process, where the optimal strategy is characterized as the minimal intervention required to keep the stock process inside a given region. The introduction of a small fixed...

We analyze how the threat of a potential future regime shift affects optimal management. We use a simple general growth model to analyze four cases that involve combinations of stock collapse versus changes in system dynamics, and exogenous versus endogenous probabilities of regime shift. Prior...

Sustainability and efficiency are potentially conflicting social objectives in natural resource management. We propose a market mechanism to allocate use rights over a stochastic resource to private managers. The mechanism endogenously determines the maximal tenure length guaranteeing that the...

This paper uses a transaction cost approach in order to classify the different policy options that are currently discussed in relation to the Kyoto protocol. It analyses the market as only one of the possible collective decision making processes, which are available to operationalize the concept...

In the high-frequency limit, conditional expected increments of fractional Brownian motion converge to a white noise, shedding their dependence on the path history and the forecasting horizon, and making dynamic optimization problems tractable. We find an explicit formula for locally...

We investigate the effect of the regime-switching transaction costs and dividends on liquidity premium and investor's optimal strategy. With reasonably calibrated parameters, we show that counter-cyclical transaction costs substantially raise liquidity premium while pro-cyclical dividends...

We investigate renewable resources when the harvesting agents face self-control problems. Individuals are conceptualized as dual selves. The rational long-run self plans for the infinite future while the affective short-run self desires to maximize instantaneous profits. Depending on the degree...

We investigate how a resource user who is present-biased manages a renewable resource stock with variable growth that could undergo a reversible regime shift (an abrupt, persistent change in structure and function of the ecosystem supplying the resource). In a discrete-time quasihyperbolic...
