What does the saving-investment (SI) relation really measure and how should the (SI) relation be measured? These are two of the most discussed issues triggered by the so called Feldstein-Horioka puzzle. Based on panel data we introduce a new variant of functional coefficient models that allow to separate long and short to medium run parameter dependence. We apply the latter to uncover the determinants of the SI relation. Macroeconomic state variables such as openness, the age dependency ratio, government current and consumption expenditures are found to affect the SI relation significantly in the long run.

This paper presents a cost-benefit analysis of three different use systems for the remaining cloud forests in Ethiopia which at present are being depleted at a rate of 8% per year. These use systems are traditional conversion to crop land, sustainable management of the forest (e.g. by growing high-quality semi-forest coffee), and strict protection. We find that conversion to cropland yields the highest net present income value for the local population, and at discount rates of 10% is even in the best interests of the country. For discount rates of at 5% or lower, sustainable forest use is in the best interests of the country. Taking into account the global benefits of biodiversity conservation and carbon storage, sustainable forest management yields the highest total economic value.

We develop a numerical filtering procedure that facilitates efficient likelihood evaluation in applications involving non-linear and non-gaussian state-space models. The procedure approximates necessary integrals using continuous or piecewise-continuous approximations of target densities. Construction is achieved via efficient importance sampling, and approximating densities are adapted to fully incorporate current information.

The paper provides Monte Carlo evidence on the performance of general-to-specific and specific-to-general selection of explanatory variables in linear (auto)regressions. In small samples the former is markedly inefficient in terms of ex-ante forecasting performance.
