This paper, conducted as part of the research activities of SOSE S.p.A., develops a simple and innovative model to evaluate the performance of local government in the provision of local public services. The model employs a reduced set of information and fewer assumptions than traditional...

We study distributive politics inside cities by analysing how local governments allocate investment projects to voters across neighbourhoods. In particular, we ask whether politicians use investment to target their own supporters. To this aim, we use detailed geo-located investment data from...

France has a track record of persistent general government deficits, partly reflecting pro-cyclical fiscal policies in upswings. This has resulted in a quadrupling of its public debt-to-GDP ratio since the 1970s to above 80% of GDP. Reducing public debt is crucial because a high level of public...

While central governments encourage intermunicipal cooperation to achieve economies of scale, municipalities are often reluctant to integrate. This paper provides new evidence on the factors explaining their resistance by exploiting a 2010 reform in France that forced non-integrated...

Global climate change and other environmental challenges require the development of new energy technologies with lower emissions. In the near-term, R&D investments, either by government or the private sector, can bring down the costs of these lower emission technologies. However, the results of...

The paper derives the optimal carbon tax in closed-form from an integrated assessment of climate change. The formula shows how carbon, temperature, and economic dynamics quantify the optimal mitigation effort. The model’s descriptive power is comparable to numeric models used in policy...

This paper discusses techniques for measuring the incidence of carbon taxes across different household income groups and provides some cross-country estimates of these effects for selected advanced countries. The general message of this paper is that distributional concerns should not...

The economics of climate change involves a vast array of uncertainties, complicating both the analysis and development of climate policy. This study presents the results of the first comprehensive study of uncertainty in climate change using multiple integrated assessment models. The study looks...

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...

The Ramsey rule for the consumption rate of discount assumes a transfer of money of a (representative) agent at one point in time to the same agent at another point in time. Climate policy (implicitly) transfers money not just over time but also between agents. I propose three alternative...
