The agro-ecosystems of semi-arid and dry sub-humid SSA are inherently dynamic. At this point in time they are also experiencing a series of complex social–ecological changes that make their future even more uncertain. To ensure that development investments made today in the small-scale farming systems that dominate these regions make sense also in a long-term perspective they should benefit the local communities over a range of potential futures. We applied a participatory scenario planning approach to a smallholder farming community in semi-arid Tanzania, exploring four alternative development trajectories for the area, to increase the robustness of current investments in small-scale water system technologies. We found that water system... |

El Acuerdo de Cooperación Técnica entre COLCIENCIAS, República de Colombia y la UNIVERSIDAD JUSTUS LIEBIG de Giessen, República Federal de Alemania, entró en toda su vigencia a partir del I9 de enero de 1976 y el mismo se prolongará hasta el 3 1 de diciembre de 1978. Los objetivos propuestos en el Convenio, relacionados con la investigación básica, la investigación aplicada y la formación de personal científico colombiano, se cumplieron de acuerdo con lo esperado. Precisamente esta publicación refleja lo fructífera que ha sido la labor de INVEMAR en los últimos años. Digo en los últimos años, pues es lógico, que buena parte de los trabajos científicos que aquí se publican, tienen sus raíces desde antes de firmarse el Convenio entre ambos países. Los... |

This paper applies a semi-parametric approach to estimating a generalised model of investments in energy installations. The model accounts for irreversibility and lumpiness of investments by linking a parametric specification of the unobservable dynamic shadow price to observed investment behaviour using a non-parametric specification of the adjustment cost function. The results suggest that marginal costs of investments in energy installations increase quickly at small investment levels, whereas the increase slows down at higher investment levels. Therefore, standard parametric adjustment cost models are likely biased such that they over-estimate small investments and under-estimate large investments. |

In this paper we evaluate empirically the impact of policies on farm investment and output decisions, considering risk-averse farmers making inter-temporal choices on current and future profits. We refer specifically to the recent reform of the CAP, while estimation and simulation results are carried out on a FADN sample of Italian arable crop farms. The main message of the paper is that a policy change that shifts resources from price support to direct payments tend to consistently reduce farm investments, mainly as a result of the increased output price volatility, which increases the level of uncertainty faced by farmers. However, this is not clearly reflected in a negative impact on farm output. |

This paper highlights the difference between secure investor property rights and loosely defined individual property rights. Globalization and fiscal decentralization have intensified this difference. On the one hand, in the presence of mobile foreign direct investments and under the arrangement of fiscal decentralization, local governments compete vigorously to offer various protections on the property rights of investors; on the other hand, local governments and developers attempt to acquire land at as low price as possible by taking advantage of the loopholes inherent in the Chinese law. Secure investor property rights together with weak protections on individuals’ land property rights is argued to be one of the major drivers of China’s rapid economic... |

The paper studies the incentive for providers to invest in new health care technologies under alternative payment systems, when the patients' benefits are uncertain. If the reimbursement by the purchaser includes both a variable (per patient) and a lump-sum component, efficiency can be ensured both in the timing of adoption (dynamic) and the intensity of use of the technology (static). If the second instrument is unavailable, a trade-off may emerge between static and dynamic efficiency. In this context, we also discuss how the regulator could use the control of the level of uncertainty faced by the provider as an instrument to mitigate the trade-off between static and dynamic efficiency. Finally, the model is calibrated to study a specific technology. |
