Purchasing power parity as an approximation to the equilibrium exchange ratio

Purchasing power parity (PPP) is re-examined in models with trade impediments and intermediate products that are not traded. A distinction is made between ‘local consumption PPP’ and ‘total consumption PPP’. These are tested on several data sets, with largely negative results.     

A comparative analysis of factors influencing the socioeconomic impacts of electric generating facilities

In recent years electric generating facility developments have become the foci of extensive controversy and resulting project delays, due in part to uncertainties and unknowns pertaining to a broad range of socioeconomic impacts which may occur. Unfortunately, socioeconomic impact research has not resolved many of these unknowns. Case study research findings have generally provided little new knowledge as to socioeeonomic impact dimensions and their causes. This paper attempts to avoid some shortcomings of prior research via a comparative analysis of some socioeconomic impact dimensions as they occurred in a sample of U.S. electric generating facilities. The paper focuses on an investigation of factors which may influence the extensiveness of developmentinduced local impacts. Both facility characteristics and characteristics of the locale which hosts facility development are suggested as possible impact determinants. Using correlational and regression procedures, expectations regarding the effects of facility size, construction time, distance to a metropolitan center, local population density and growth rates, and local labor force characteristics on overall “community service” impacts are examined. Results indicate both consistency and inconsistency with prior research conclusions, and suggest that some characteristics of the development and the development area are important in projecting the likely levels of some facility-induced socioeconomic impacts.     

Technology Adoption and Its Impact on Production Performance of Dairy Operations

Data from the 1993 Agricultural Resource Management Study were used to examine the impact of technology adoption on production performance of a sample of dairy farms. Findings showed that the adoption of a capital- or a management-intense technology would measurably lower the likelihood of a farmer being in the lowest quartile of production performance. The economic costs of milk production by the top-performance group were estimated to be 53% lower than those by the low-performance group, providing evidence of the importance of improved production practices to the viability of many dairy operations.     

Site selection to test an integrated approach to agricultural research for development: combining expert knowledge and participatory Geographic Information System methods

The sub-Saharan Africa challenge programme is designed to address the problems of failures of agricultural markets, inappropriate policies and natural resource degradation, that contribute to the continuing deterioration of livelihoods and food security in the region. It is seeking to do this by redefining the roles of scientists and farmers through collaborative learning processes, addressing questions about the level, timing, type and formof participation, as well as themost effective approaches andmethods to foster them. The research domains of the programme deal with sustainable intensification of smallholder agriculture, the sustainable management of natural resources, the development of efficient markets, and the promotion of enabling policies. One question that was addressed in designing the initiative was deciding where to work so as to maximize the chances of successful testing of this new approach, so that it would lead to significant reductions of rural poverty. A participatory process was put in place to design a framework to accomplish this site selection, and then to apply it in west, east and southern Africa. A mixture of spatial data analysis and expert knowledge on spatial and non-spatial factors was used, and one primary site in each region was identified to form the basis for the next phase of the challenge programme. Several lessons were learnt from the process, including the importance of adapting themethods to actual conditions, the increased utility of targetting when the quantitative and the qualitative are freely combined, and the continued need for baseline spatial and non-spatial data to improve the targeting of research in the future that is designed to alleviate poverty in sub-Saharan Africa.     

‘RE‐OPENING THE BLACK BOX’: THE STORY OF IMPLEMENTING A RISK ANALYSIS METHOD IN A FRENCH LOCAL GOVERNMENT

This research is a study of the implementation of a risk analysis method (RAM) in a French local government. Based on the sociology of translation framework, this study shows that the success of the implementation of this management device is due to the transformation of its initial characteristics. Indeed, the RAM was initially designed to analyze the risks of outsourcing public services and thereby to aid elected officials with decision making. But in the hands of the actors in charge of its implementation, it progressively became a means for the members of the administrative services to inform elected officials about the consequences of their choices. This paper thus describes the ‘trajectory’ of this management device in a local government and, in doing so, emphasizes how it progressively became what it is (and what it is not) at present in this local government.
