The Economic Value of Land-based Ecosystem Services in Portugal
This study estimates the economic value of seven land based ecosystem services for mainland Portugal in 2018. The estimated services are Climate Regulation, Drought Regulation, Erosion Prevention, using the market price methodology, and Food Supply, Pollination, Recreation and Water Purification using a meta-analytic benefit transfer function. By estimating a unique meta-analytic benefit transfer function for each service, the commodity consistency condition is addressed. Different welfare measures were not pooled together and methodological variables are not included in the vector of explanatory variables. The results are spatially explicit at the hectare level providing the benchmark to which the consequences of land-use changes to the value of ecosystem services and, therefore, to the welfare of local populations can be adequately assessed.
Crowdfunding Vs. Taxes
The effect of the payment vehicle (PV) on economic valuation estimates has been addressed since the early literature on stated preferences studies. Particularly, some studies have focused on willingness to pay (WTP) sensitivity to mandatory/collective vs. voluntary/individual PVs, by comparing tax increases or redistribution based on specific taxes with donation-like contributions. These two payment schemes may induce different types of strategic behavior and eventually free riding by the economic agents involved. We conducted a choice experiment through a face-to-face survey held in 2020 for a representative sample of the Portuguese population. We investigate the national population's WTP t...
Innovation and Environmental Policy
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 portfolio that includes a tax on the polluting good combined with optimal innovation subsidy policies is less costly than increasing the price of the polluting good alone. Moreover, a discriminating innovation subsidy policy is preferable to a non-discriminating one.

The Impact of Industrial Pollution Exposure on Hospital Admissions
The effect of individual-level daily silicon dust exposure from cement production on the probability of hospital admissions for respiratory-related reasons is examined. The dataset was collected at the cement plant in Bryanskii region, Russia. We use an aerodynamic dispersion model to calculate pollutants' exposure. We find a significant impact of silicon dust on hospitalizations for children and elderly adults. We identify a non-linear response of the individual probability of hospital admissions to the average daily inhaled concentrations in the city area where exposure is higher. Our findings contribute to better inform policymakers aiming at reducing industrial air pollution exposure in Russia.
