This paper analyses the relationship between rural poverty and soil degradation in the context of a shifting cultivating community. A deterministic optimal control model demonstrates how a representative household's labour allocation affects the natural resource base on which its livelihood...

A new instrument for hedging weather risks has made its appearance in the financial arena. Trade in 'weather derivatives' has taken off in the US, and interest is growing elsewhere. Whilst such contracts may be simply interpreted as a new tool for solving a historical problem, the question...

Monetary policy in the US is characterized by a substantial degree of inertia. While in principle this may well be the outcome of an optimizing central bank behavior, the ability of any derived policy rule to match the data relies on so large weights for interest rate smoothing into policy...

Non-strategic firms with rational expectations make investment and emissions decisions. The investment rule depends on firms' beliefs about future emissions policies. We compare emissions taxes and quotas when the (strategic) regulator and (nonstrategic) firms have asymmetric information about...

Firms grant to their employees non-tradable stock options as an incentive device. Is the opportunity cost of issuing these options equal to the amount the company would receive if it sold the same options to outside investors? No, it is not, since the options granted to employees are non...

Selectivity bias caused by protest responses in Contingent Valuation studies can be detected and corrected by means of sample selection models. This paper compares two methods: the Heckman 2-steps method and the full ML, applied to data on forest recreation - where WTP is elicited as a...

Investor confidence is a necessary condition for the development of emerging markets. Investors recognize that since market-oriented reform policies may be reversed or hindered, they face the risk of ex post policy changes with redistributive impact on investment returns. We argue that a...

The paper describes an algorithm for the generation of a general class of precedence- and resource-constrained scheduling problems. Easy and hard instances for the single- and multi-mode resource-constrained project scheduling problem are benchmarked by using the state of the art...

We consider the resource-constrained project scheduling problem (RCPSP). The focus of the paper is on a formal definition of semi-active, active, and non-delay schedules. Traditionally these schedules establish basic concepts within the job shop scheduling literature. There they are usually...
