The effects of land-use development policies on forest management

Cunha-e-Sá, Maria A.; Franco, Sofia F.

This paper develops a model of a forest owner operating in an open-city environment, where the rent for developed land is increasing concave in nearby preserved open space and is rising over time reflecting an upward trend in households’ income. Thus, our model creates the possibility of switching from forestry to residential use at some point in the future. In addition it allows the optimal harvest length to v...

Forest management in an urbanizing landscape

Cunha-e-Sá, Maria A.; Franco, Sofia F.

This paper aims at building a theoretical framework to examine the impact of development pressure on private owner’s forest management practices, namely, on regeneration and conversion cut dates. As the rent for developed land is rising over time, our model creates the possibility of switching from forestry to residential use at some point in the future, thus departing from the Faustmann’s traditional setup. Co...

Urban containment: An effective tool for environmental protection?

Cunha-e-Sá, Maria A.; Franco, Sofia F.

This paper examines the effectiveness of urban containment policies to protect forestland from residential conversion and to increase the provision of forest public goods in the presence of irreversible investments and policy uncertainty. We develop a model of a single landowner that allows for switching between competing land uses (forestry and residential use) at some point in the future. Our results show tha...

Protest attitudes and stated preferences: Evidence on scale usage heterogeneity

Cunha-e-Sá, Maria A.; Nunes, Luis C.; Otrachshenko, Vladimir

We contribute to the stated preference literature by addressing scale usage heterogeneity regarding how individuals answer attitudinal questions capturing lack of trust in institutions and fairness issues. Using a latent class model, we conduct a contingent valuation study to elicit the willingness-to-pay to preserve a recreational site. We find evidence that respondents within the same class, that is, with si...

Urban deforestation and urban development

Cunha-e-Sá, Maria A.; Franco, Sofia F.; Rosa, Renato

This paper has developed a model of a single forest owner operating with perfect foresight in a dynamic open-city environment that allows for switching between alternative competing land uses (forest and urban use) at some point in the future. The model also incorporates external values of an even-aged standing forest in addition to the value of timber when it is harvested. Timber is exploited based on a multip...

Protesting or justifying? A latent class model for contingent valuation with at...

Cunha-e-Sá, Maria A.; Madureira, Lívia; Nunes, Luis C.; Otrachshenko, Vladimir

This article develops a latent class model for estimating willingness-to-pay for public goods using simultaneously contingent valuation (CV) and attitudinal data capturing protest attitudes related to the lack of trust in public institutions providing those goods. A measure of the social cost associated with protest responses and the consequent loss in potential contributions for providing the public good is pr...

Innovation and environmental policy: Clean vs. dirty technical change

Cunha-e-Sá, Maria A.; Leitão, Alexandra; Reis, Ana B.

We study a two sector endogenous growth model with environmental quality with two goods and two factors of production, one clean and one dirty. Technological change creates clean or dirty innovations. We compare the laissez-faire equilibrium and the social optimum and study first- and second-best policies. Optimal policy encourages research toward clean technologies. In a second-best world, we claim that a port...

Experimentation with accumulation

Cunha-e-Sá, Maria A.; Santos, Vasco

We study signal-dependent experimentation in the presence of accumulation and show that the passive-learner’s action surprisingly coincides with the experimentor’s when the unknown term is the one determining the decay rate of the stock, while they differ when the parameter being learned is the one measuring the accumulation rate. These results highlight the importance of the dynamic structure of the problem in...
