Paroush and Wolf (1989) modeled output hedging in the presence of basis risk. They showed that (in the absence of scale shift) the optimal hedging and output fall in response to basis risk. However, they used a second-order Taylor's approximation of the utility function. Also, they did not show...

This paper develops a general theoretical framework within which a heterogeneous group taxpayers confront a market that supplies a variety of schemes for reducing tax liability, and uses this framework to explore the impact of a wide range of anti-avoidance policies. Schemes differ in their...

We use Malliavin calculus and the Clark-Ocone formula to derive the hedging strategy of an arithmetic Asian Call option in general terms. Furthermore we derive an expression for the density of the integral over time of a geometric Brownian motion, which allows us to express hedging strategy and...

This paper looks at the evolution of the world wine industry in the period 1961-2005. A particular stylized fact is the appearance of non-traditional producing and exporting countries of wine from the beginning of the nineties. We show that the success of these new producing and exporting...

Cecchetti et al. (2006) develop a method for allocating macroeconomic performance changes among the structure of the economy, variability of supply shocks and monetary policy. We propose a dual approach of their method by borrowing well-known tools from production theory, namely the Farrell...

We study the screening problem that arises in a framework where, initially, the agent is privately informed about both the expected production cost and the cost variability and, at a later stage, he learns privately the cost realization. The specifi?c set of relevant incentive constraints, and...

Untreated wastewater being directly discharged into rivers is a very harmful environmental hazard that needs to be tackled urgently in many countries. In order to safeguard the river ecosystem and reduce water pollution, it is important to have an effluent charge policy that promotes the...

We examine the use of subsidies to R&D in a mixed and a private duopoly market. We show that the socially optimal R&D subsidy is increasing in the degree of spillovers but it is lower in the private duopoly. The optimal R&D subsidy leads to an increase in total R&D and production, however, it...

We present a model of spatial price discrimination where R&D spillovers are endogenous as they depend on firms' location. We establish that both the distance between locations and R&D efforts are increasing functions of the transportation cost coefficient and show that there is a continuum of...

We present a three-stage game where two firms choose location, R&D and price, under the assumption that R&D spillovers depend on firms' location. That is, the closer firms are to each other, the greater the benefit they receive from their rivals' efforts in quality-enhancing R&D. We show that...
