Modes of production in home maintenance: accounting for the choice between formality,off the books and self‐provisioning

Households depend on the existence of a home, and therefore, maintenance plays an important social and economic role. Formal outsourcing is often overestimated here and alternative modes, such as informal outsourcing and do‐it‐yourself (DIY), are overlooked. This paper estimates and accounts for the choice of one mode of production in Flemish households. First, the different modes of production are quantified according to two different methods. Further, an explanation of the choice made is constructed. The complexity of maintenance work has an impact as well as the dimensions of social and cultural capital. Factors such as dexterity, occupational acquaintance with maintenance work, social trust and social contacts play a role. Finally, a model of a sequence of decisions is tested. This ramification mechanism shows that the primary choice is formal commissioning or not, inspired by technical complexity. The second choice between off‐the‐books outsourcing and DIY is influenced by the capital resources of the households.     

The geneva hydrocarbon protocol: Economic insights from a belgian perspective

This paper extends the methodology for the economic analysis of tropospheric ozone regulation reported in Repetto (1987). Firstly, the acid rain objective is explicitly incorporated by assigning an additional benefit to the acidifying precursors of ozone. Secondly, we introduce the transboundary dimension which is of particular importance to Europe. The methodology is applied to the evaluation of the costs and benefits of the Geneva Protocol on hydrocarbons for Belgium.     

Optimal location of new forests in a suburban region

This paper looks at the optimal location of new forests in a suburban region under area constraints. The methodology takes into account use benefits, non-use benefits (both bequest and existence values), opportunity costs of converting agricultural land, as well as planting and management costs of the new forest. The recreational benefits of new forest sites are estimated using function transfer techniques. We show that the net social benefit of the total afforestation project varies up to a factor 6. The recreational value of a site varies considerably with the available substitutes.     

A toolkit in SAS for the evaluation of multiple imputation methods

This paper outlines a strategy to validate multiple imputation methods. Rubin's criteria for proper multiple imputation are the point of departure. We describe a simulation method that yields insight into various aspects of bias and efficiency of the imputation process. We propose a new method for creating incomplete data under a general Missing At Random (MAR) mechanism. Software implementing the validation strategy is available as a SAS/IML module. The method is applied to investigate the behavior of polytomous regression imputation for categorical data.     

Assignment Games Satisfy the CoMa-Property

A balanced game satisfies the CoMa-property if and only if the extreme points of its core are marginal vectors. In this note we prove that assignment games satisfy the CoMa-property. Journal of Economic Literature Classification Numbers: C71, C78.     

A political economy model of road pricing

In this paper, we use a simple majority voting model to study the introduction of urban congestion tolls. The model allows for different types of uncertainty and considers different uses of the toll revenues. The following results are obtained. First, we show that individual uncertainty with respect to modal substitution costs may imply that a majority votes against road pricing ex ante, although a majority would have been in favor after its introduction ex post. Moreover, if a majority is against road pricing ex ante, there will also be no majority for organizing an experiment that would take away the individual uncertainty. Second, political uncertainty with respect to the use of the revenues corroborates the finding that ex ante more voters will be against the introduction of tolls. Third, both types of uncertainty suggest that fewer voters are against road pricing when toll revenues are used to subsidize public transport than when they are redistributed to all voters. Importantly, the results of this paper are consistent with a number of recent empirical observations on efforts to introduce road pricing, including the systematic rejection of road pricing in referenda, the more favorable attitudes towards road pricing after than before its introduction, and tying the toll revenues to support public transport.     

Yet another look at temporal aggregation in diffusion models of first-time purchase

This paper gives yet another look at the impact of temporal aggregation on the parameter estimates for the familiar Bass diffusion model. It is shown that aggregation leads to larger values of the innovation parameter p and that it is leads to smaller values of the imitation parameter q, at least in theory. The last finding is in contrast with the results in Technological Forecasting and Social Change [51 (1996) 265]. We use simulation experiments to substantiate our results.
