In his seminal paper of 1928, Ramsey conjectured that if agents discounted the future differently, in the long run all agents except the most patient would live at the subsistence level. The validity of this conjecture was investigated in different environments. In particular, it has been...

We introduce a continuous time overlapping generations demographic model, in which a social planner seeks to generate an optimal policy for influencing the demographic change of the underlying population in a neoclassical growth model. The model has the notable feature that the underlying state...

Energy and climate policies are usually seen as measures to internalize externalities. However, as a side effect, these policies redistribute wealth between consumers and producers, and within these groups. While redistribution is seldom the focus of the academic literature in energy economics,...

We present a decomposition approach for integrated assessment modeling of climate policy based on a linear approximation of the climate system. Our objective is to demonstrate the usefulness of decomposition for integrated assessment models posed in a complementarity format. First, the...

Greenhouse gas policies confront the trade-off between the costs of reducing emissions and the benefits of avoided climate change. The risk of uncertain and potentially irreversible catastrophes is an important issue related to the latter, and one that has not yet been well incorporated into...

This work follows the series of studies conducted in Ipea, in order to compare the efficiency of the Brazilian health system to health systems of other countries. We evaluate the efficiency of expenditure in health care provision by comparing various output measures (life expectancy; infant...

One of the key decisions that economists working on integrated studies of climate change face is the selection of the method of accounting for damages resulting from possible climate change across a long temporal scale and the method for the intertemporal comparison of the costs associated with...

This paper evaluates product efficiency in the Spanish automobile market. We use non parametric frontier techniques in order to estimate product efficiency scores for each model. These scores reflect the minimum price for which each car could be sold, given the bundle of tangible features it...

By interlinking power systems, significant welfare gains can be achieved. However, different approaches for coupling electricity markets exist. A recent development in this field is the implementation of flow-based market coupling (FBMC) in Central Western Europe (CWE). Indeed, FBMC has proven...

Despite favourable ecological and economic results, many developing countries have not yet adopted an integrated pesticide management (IPM). Given rising marginal costs and diminishing marginal benefits from IPM technology transfer, an optimal control framework is used to identify optimal rates...
