To decarbonize the power sector policy-makers need to commit to long-term credible rules for climate and energy policy. Otherwise, time-inconsistent policy-making will impair investments into low-carbon technologies. However, the future benefits and costs of decarbonization are subject to...

This paper proposes a model where heterogeneous firms choose whether to undertake R&D or not. Innovative firms are more productive, have larger investment opportunities and lower own funds for necessary tangible continuation investments than non-innovating firms. As a result, they are...

In many countries entrepreneurship is promoted through tax reductions for small businesses and by various government support schemes. We analyze the effects of such policies to subsidize small businesses in a setting where both the risk-return characteristics of the selected innovation project...

We investigate conditions that aggravate market failures in energy innovations, and suggest optimal policy instruments to address them. Using an intertemporal general equilibrium model we show that “small” market imperfections may trigger a several decades lasting dominance of an incumbent...

This paper addresses two basic issues related to technological innovation and climate stabilisation objectives: i) Can innovation policies be effective in stabilising greenhouse gas concentrations? ii) To what extent can innovation policies complement carbon pricing (taxes or permit trading) and...

Using data from 1988 to 2007, we examine to what extent bilateral aid flows of an individual donor to a country depend on aid flows from all other bilateral and multilateral donors to that country. We thereby want to assess to what extent donor coordination, free-riding, selectivity,...

We show that, in competition between a developed country and a developing country over environmental standards and taxes, the developing country may have a ‘second-mover advantage.' In our model, firms do not unanimously prefer lower environmental-standard levels. We introduce this feature to...

This paper deals with a classic development question: how can the process of economic development – transition from stagnation in a traditional technology to industrialization and prosperity with a modern technology – be accelerated? Lewis (1954) and Rostow (1956) argue that the pace of...

A windfall of natural resource revenue (or foreign aid) faces government with choices of how to manage public debt, investment, and the distribution of funds for consumption, particularly if the windfall is both anticipated and temporary. We show that the permanent income hypothesis prescription...
