A productivity study of the Norwegian building industry

Slow productivity growth in the building and construction industry is often put forward as the cause of rising building costs. In view of the importance of the building sector in the national economy, factual empirical knowledge is hard to come by. The few studies found are usually carried out on a sectoral level and based on time-series data. However, to come to grips with the real causes for slow productivity growth, one has to analyze at the microlevel of actual decision making. Our study is based on establishment data for 1986. The method of analysis is the deterministic frontier approach. The efficiency distributions show large variations with average structural efficiency about 20 percent. Thus, there is significant scope for productivity improvement if average performance can catch up with best practice.The refereeing process of this article was handled through T.G. Cowing.     

Targeting public services through the unequal treatment of unequals

When private goods are publicly provided, government authorities have to determine the distribution of in-kind benefits to recipients. In this paper, the public service provider is assumed to maximize utility defined over public service supply to different target groups, given a budget constraint. The production technology is target-group-specific and depends on the ability of each target group to produce service outcomes. Three benchmark allocation principles are identified: equality of treatment (ET), equality of outcome (EO), and equality of marginal cost (EMC). These principles can be considered to be consistent with special cases of a public preference model, which allows for compromises between different allocation principles. The condition of technological dominance implies that there is a clear-cut equity–productivity trade-off, whereas violations of this condition may reduce the significance of the trade-off.     

Preisdeterminanten des Stromgroßhandels in Frankreich

This article provides a model-based analysis of the French spot market for electricity. Therefore a cost optimizing dispatch model is applied in order to derive a broader understanding of the liberalized electricity market in France considering empirical spot market prices in 2009. At first analysis of market structure and power plant mix is done in accordance with the european framework. The state of supply side competition is suggested as well. Due to the high portion of nuclear energy in the French energy mix the technical availability forecast of the plants plays a crucial role during the price formation on the wholesale market. As a result prices determined by the model are highly correlated with the French spot market. The results suggest a functioning pricing mechanism although deviations occur by ex-ante uncertain demand or unscheduled non-usability of generating units.     

Trends in living conditions and satisfaction among poorer older South Africans: objective and subjective indicators of quality of life in the October Household Survey

The majority of South Africa's older population is income poor and lives in multigeneration households. Since the first democratically elected government came into power in 1994, South Africans have been promised ‘a better life for all’. A range of policies and programmes has been implemented to improve the living standards and quality of life of the poor. The article asks how the older poor have benefited from government interventions in the period 1995–8. Drawing on data compiled from Statistics South Africa's household surveys in 1995 and 1998 (n=20 000–30 000 households), a set of over 35 objective and subjective indicators broken down by income and younger and older households is reviewed. Older households include at least one member over 60 years of age. Results show that access to services and opportunities improves systematically from poor to rich households. Major material gains for the poor and older households during the review period include access to clean water, electricity and home ownership. Older poor households with better access to services and opportunities are more likely to express overall satisfaction with their living circumstances. The study concludes that the most effective mechanism for poverty alleviation appears to be the non-contributory, means-tested state old-age pension, which lifts some households out of the most disadvantaged bottom income group. Policies under discussion promise further opportunities for empowering poor households with older members.     

Telecommunications in developing countries

The conditions in which telecommunication services are established and expanded in the developing countries are very different from those experienced in the industrial nations. The author provides insight into the peculiarities of the telecommunication sector in developing countries, discussing characteristics related to the structure of the sector, system size and quality, telecommunications as a business, limitations to faster growth, and some particular problem areas, including the impact on economic development, especially in rural areas, training and education directed towards high technical and managerial positions, and the manufacture of equipment.     

The supply side in a post-Keynesian two-sector model

Summary In order to avoid missing the wood for trees a brief summary of the results having been obtained above appears to be appropriate.Firstly, we regard it as a result in itself of the present paper to have presented a two-sector model encapsulating a Kaleckian (and Kaldorian) vision of a capitalist economy, a model in which supply conditions of primary products take up a prominent position.Secondly, it belongs to the main results of the paper that it has laid bare, through the model presented, an astoundingly simple pattern in the way economic key-concepts such as activity, employment and distributive shares are affected by on one hand the demand side (which has so far captured an excessive amount of attention in macroeconomic modelling) and on the other hand the largely neglected supply side of the economy.Thirdly, by means of an arbitrary but not implausible numerical example we have attempted to indicate how changes in activity and distributive shares caused by exogeneous changes on the demand and supply side of the economy, respectively, are in themselves crucially dependent on (the assumptions concerning) the supply elasticity of primary products.The notation applied will be as follows C consumption - C ⁰ autonomous element of the consumption function - I investment (gross) - A autonomous expenditure - S savings (gross) - U stock of the primary product - Q real output (not necessarily real income) (gross) - Y income (gross) - W wage bill - L employment - w money wage rate - p price level - mark-up factor - level parameter of the production function pertaining to the primary sector - a labour-input coefficient of the industrial sector - b raw-material input coefficient of the industrial sector - s _w marginal propensity to save out of wages - s marginal propensity to save out of profits - s (weighted) average ofS _w ands - (unit) raw material costs as a proportion of total (unit) prime costs - share of wages in total income - E _{y, x} partial or total elasticity ofY with respect toX.

Managing interaction for learning and value creation in exchange relationships

Firms create value by establishing and maintaining appropriate exchange relationships. However, beyond the generally recognized importance of trust and commitment, there is a lack of specific cues as to how such value creation can be managed. In an attempt to gain more insight this study examines the success formulas in three different types of interactions in exchange relationships. The purpose is to investigate how different types of interactions can be managed so that buyer firms make important contributions to the development of their suppliers' capabilities. The study empirically examines how inter-organizational management facilitates value creation in three different types of interactions in exchange relationships: unilateral learning, unilateral development, and bilateral learning. This study uses a partial least squares analysis (PLS) to analyze survey data from 142 exchange relationships in the seafood industry. The main contribution to the literature is the assessment of how various types of inter-organizational management promote value-creation initiatives (such as information supply and coaching), and ultimately, value creation.
