The purpose of the present paper is to describe the role of uncertainty and technical change in an environmental … context. Which impact does ecological uncertainty have on physical and R&D investments' decisions? How are pollution … trajectories modified when uncertainty is taken into account? To reply to these questions we modify the ETC-RICE model described in …

activity on optimal consumption and investment. Here, learning introduces two sources of risk about future payoffs: structural … uncertainty and uncertainty from the anticipation of learning. The latter renders control and learning nonseparable. We present … decreases optimal consumption are provided. The effect depends on the strengths and directions of the two sources of risk, which …

We present a model of firm investment under uncertainty and partial irreversibility in which uncertainty is represented … by a jump diffusion. This allows to represent both the continuous Gaussian volatility and the discontinuous uncertainty … related to information arrival, sudden changes and large shocks. The model shows how both sources of uncertainty negatively …

Consumers benefit from such … depreciates over time and has a cost in terms of current consumption, the model determines an optimal investment in literacy. The … aggregate data, we find a strong effect of financial literacy on wealth accumulation and national saving, and also show that …

We derive robust predictions on the effects of uncertainty on short run investment dynamics in a broad class of models … of UK firms and a stock returns-based measure of uncertainty. As predicted we find that uncertainty reduces firms …
