I develop a dynamic model of private provision of public bads allowing investments in technologies. The analysis is tractable and the MPE unique. The framework is used to derive optimal incomplete contracts in a dynamic setting. While the noncooperative equilibrium is very inefficient,...

I study dynamic private provision of public goods (or bads) when agents (or countries) can invest in cost-reducing technologies and sign incomplete contracts. The model leads to a dynamic common pool problem that is more severe than its static counter-part. Nevertheless, a sequence of short-term...

We analyze a repeated game in which countries are polluting as well as investing in technologies. While folk theorems point out that the first best can be sustained as a subgame-perfect equilibrium when the players are sufficiently patient, we derive the second best equilibrium when they are...

We characterize the optimal policy and policy instruments for self-enforcing treaties when countries invest in green technology before they pollute. If the discount factor is too small to support the first best, then both emissions and investments will be larger than in the first best, when...

We present a novel benefit of linking emission permit markets. We consider a dynamic setting, and let the countries issue permits non-cooperatively. With exogenous technology levels, there are only gains from permit trade if countries are different. With endogenous technology, however, we show...

This paper seeks to give insights into how domestic voters form their preferences pro or contra compliance with IEAs and therefore how public concern for the environment and interest group activity influence national compliance behaviour. Three hypotheses are developed. First, compliance...

I explore possible impacts of reciprocal preferences on participation in international environmental agreements. Reciprocal countries condition their willingness to abate on others' abatement. No participation is always stable. A full or majority coalition can be stable, provided that...

International climate negotiations have been troubled by mutual mistrust. At the same time, a hope seems to prevail that once enough countries moved forward, others would follow suit. If the abatement game faced by climate negotiators is a Prisoners' Dilemma, and countries are narrowly...

We study the delegation of climate policy to a supranational environmental authority. We demonstrate that the authority faces a dynamic inconsistency problem that leads to welfare losses. The losses can be kept small if the mandate of the authority penalizes the local cost of emissions heavily,...

Out of a total of 2,976 double tax agreements (DTAs), some 60% are signed between a developing and a developed economy. As DTAs shift taxing rights from capital importing to capital exporting countries, the prior would incur a loss. We demonstrate in a theoretical model that in a deal one...
