Empirical studies on industry lobbying sometimes reveal that certain firms within an industry behave atypically in that they promote cost driving regulations like, e.g., environmental standards. For analysing this phenomenon of 'strategic lobbying1, the present paper combines a heterogeneous...

This article investigates efficient policies against global warming in the case of multiple greenhouse gases. In a dynamic optimization model conditions for an efficient combination of greenhouse gases are derived. The model is empirically specified and adapted to a simulation approach. By...

The present paper develops a model of endogenous policy making where a 'low regulation' party / and a 'high regulation' party h compete for campaign contributions spent by a dominating low-cost firm within a regulated industry. The model shows that assuming an endogenous market structure...

This paper provides a rationale for taxing waste exports when closure risks are endogenous in that they depend on the importing country's accumulated stock of waste. The paper shows that the optimal time path of waste exports requires a progressively increasing tax rate which even surmounts a...

The probability that an agent takes a certain action or a certain event occurs depends often on the actions taken by some agents. If this probability depends not only on current actions but on the sum of all past actions, these stock-dependent risks imply an intertemporal effect. In the present...
