The challenge of achieving socially optimal incentives for innovation in public goods faces twin market failures: a market failure to adequately promote public goods invention and a market failure to implement innovative public goods once developed. Though innovation in private goods sometimes...

I investigate a simple model of advance-purchase contracts as a mode of financing costly projects. An entrepreneur has to meet some capital requirement in order to start production and sell the related good to a limited number of potential buyers who are privately informed about their...

I investigate a simple model of advance-purchase contracts as a mode of financing costly projects. The analysis can easily be reinterpreted as a model of the monopolistic provision of excludable public goods under private information. An entrepreneur has to meet some capital requirement in order...

Technological innovations are inherently problematic (risky, uncertain, possess public goods properties (enhances free-riding since it is easy to steal), but once they succeed, they create negative externalities for incumbents in the form of economic resources redistribution. Economic resources...

The literature on patent buyouts has focused on single-economy settings, where buyouts are welfare improving relative to patents unless there are frictions such as imperfect information or commitment problems. We expand the analysis to a world with two heterogeneous countries featuring different...

How should governments best allocate their budget to support private research activities? The consensus in the literature is that sector-specific R&D support policies should be increasing in the degree of compatibility of sectoral innovation with the practices of the wider economy. Using a...

We show that, in a model without commitment to future policies, geoengineering breakthroughs can have adverse environmental and welfare effects because they change the (equilibrium) carbon taxes. In our model, energy producers emit carbon, which creates a negative environmental externality, and...

There is widespread concern that climate policy is moving too slowly and that decarbonization of economic development is coming too late for effective climate protection. We analyze three different effects that emerge endogenously during decarbonization and amplify current policies: growing...

In this paper, we examine the similarities and the differences between two global problems, the Coronavirus pandemic and climate change, and the extent to which the experience with the Covid19 pandemic can be of use for tackling climate change. We show that both problems share the same...

This paper develops a theoretical model to study how investment decisions in innovation taken by a single agent are influences by environmental externalities produced by investment decisions taken by other agents. The model acts in a dynamic framework, where knowledge stock represents the...
