We study the optimal timing of adoption of a cleaner technology and its effects on the rate of growth of an economy in the
context of an AK endogenous growth model. We show that the results depend upon the behavior of the marginal utility of environmental
quality with respect to consumption. When it is increasing, we derive the capital level at the optimal timing of adoption.
We show that this capital threshold is independent of the initial conditions on the stock of capital, implying that capital-poor
countries tend to take longer to adopt. Also, country-specific characteristics, as the existence of high barriers to adoption,
may lead to different capital thresholds for different countries. If the marginal utility of environmental quality decreases
with consumption, a country should never delay adoption; the optimal policy is either to adopt immediately or, if adoption
costs are “too high”, to never adopt. The policy implications of these results are discussed in the context of the international
debate surrounding the environmental political agenda.

This article develops a latent class model for estimating willingness-to-pay (WTP) for public goods using simultaneously contingent valuation (CV) and attitudinal data to identify individuals with similar characteristics, such as WTP and protest attitudes. We find evidence that the answer to the CV question influences the responses to the attitudinal questions. In our case, this influence reflects rational behavior (budget constraint issues) and justification biases related to protest reasons, such as lack of trust in institutions or fairness issues with respect to the distribution of the burden of preservation. The results from our empirical application confirm the importance of accounting for those biases. 相似文献
