چکیده
Optimal climate policy is studied in a Ramsey growth model. A developing economy weighs global warming less, hence is more likely to exhaust fossil fuel and exacerbate global warming. The optimal carbon tax is higher for a developed economy. We analyze the optimal time of transition from fossil fuel to renewables, amount of fossil fuel to leave in situ, and carbon tax. Subsidizing a backstop without an optimal carbon tax induces more fossil fuel to be left in situ and a quicker phasing in of renewables, but fossil fuel is depleted more quickly. Global warming need thus not be alleviated.

متن کاملCall Me Maybe: Experimental Evidence on Using Mobile Phones to Survey Microenterprises
High-frequency data is useful to measure volatility, reduce recall bias, and measure dynamic treatment effects. We conduct the first experimental evaluation of high-frequency phone surveys in a developing country or with microenterprises. We randomly assign microenterprise owners to monthly in-person, weekly inperson, or weekly phone interviews. We find high-frequency phone surveys are useful a...
متن کاملThe Role of Institutions in the Dynamic Effects of Oil Revenues in Oil Economies
The purpose of this paper is to investigate the system of oil revenues effects on the production performance of oil-rich countries in both short and long-run.
