Exploring consistency between stated and revealed preferences for the plastic bag ban policy in Chile

Submitted by Cristóbal Vásquez on

This paper exploits individual-level data before the implementation of a national policy to understand the factors driving avoidance of plastic consumption and explore potential inconsistencies between revealed and stated preferences for a plastic bag ban policy. We estimate a bivariate ordered probit model that allows us to account for a potential correlation between these types of preferences. The data reveals that while 71% of respondents take a reusable bag for shopping, only 58% of the sample state to strongly agree with prohibiting plastic bags.

There is no economic case for new coal plants in India

Submitted by Ishita Datta on

India is the world’s third-largest emitter of CO2 and coal-fired power plants contribute approximately half of India’s CO2 emissions. Indian government policies assume a significant expansion of coal-fired power in India over the next two decades. This paper compares the costs of coal and renewable power, including  quantifiable domestic external costs, in 2018 as well as projections for 2025. Our estimate for the environmental cost of coal is 2.4 US ¢/KWh (1.64 Rs.KWh) in the financial year 2018–19.
