In this paper we model expenditure on housing for owners and renters by means of endogenous switching regression models using
cross-section data. We explain the share of housing in total expenditure from family characteristics and total expenditure,
where the latter is allowed to be endogenous. We apply various existing parametric and semiparametric techniques for cross-section
data. Exogeneity of total expenditure is rejected for the parametric models but not for most semiparametric models. The results
are compared on the basis of budget elasticities and graphs of the estimated relationship between the budget share spent on
housing and the logarithm of total expenditure.

This paper studies a two-machine flow shop scheduling problem with a supporting precedence relation. The model originates from a real production context of a chemical factory that produces foam-rubber products. We extend the traditional two-machine flow shop by dividing the operations into two categories: supporting tasks and regular jobs. In the model, several different compositions of foam rubber can be mixed at the foam blooming stage, and products are processed at the manufacturing stage. Each job (product) on the second machine cannot start until its supporting tasks (parts) on the first machine are all finished and the second machine is not occupied. The objective is to find a schedule that minimizes the total job completion time. The studied problem is strongly NP-hard. In this paper, we propose a branch-and-bound algorithm incorporating a lower bound and two dominance rules. We also design a simple heuristic and an iterated local search (ILS) algorithm to derive approximate solutions. The performances of the proposed algorithms are examined through computational experiments. 相似文献

While age is the variable most often used to explain household recycling behavior, research findings reveal only limited or contradictory effects. This study demonstrates the utility of several additional variables related to age in regard to explaining the effect of aging on household recycling behavior. These variables are generativity, available time, and perceived skills. By drawing on the theory of planned behavior, this paper offers a model that clarifies how age indirectly influences household recycling behavior. The model is tested on a stratified sample, and the results are analyzed through mediation tests and structural equation modeling. While aging is associated with lower levels of enthusiasm for recycling, more skills and available time allow recycling to be accomplished with increased ease. Finally, the results enable an explanation of the previous contradictory results about age effects and lead to managerial and societal recommendations on how household recycling can be effectively promoted. 相似文献

Modern customs administrations aim to both facilitate legal trade and combat fraud. To meet this dual objective, many customs administrations in developing countries must give risk management a highly prominent role. In this context of modernisation, this paper first provides stylised facts on the performance of the customs controls carried out at the Gabon border. Then, we compare Gabon′s granular import customs data with international trade statistics. Based on this comparison, we identify undetected fraud and present a methodology to target ex post audits. Finally, we define indicators to monitor the performance of customs valuation controls. 相似文献

Performance measurement is one of the most studied subjects in financial literature. Since the introduction of the Sharpe ratio in 1966, a large variety of new measures has appeared constantly in scientific journals as well as in practitioners' publications. The most complete and significant studies of performance measures, so far, have been written by Aftalion and Poncet, Le Sourd, Bacon, and Cogneau and H übner. A review of the most recent literature led us to collect several dozen measures that we classify into four families. We first present the class of relative measures, starting with the Sharpe ratio. Secondly, we analyse absolute measures, beginning with the most famous one ‐ the Jensen alpha. Thirdly, we study general measures based on specific features of the return distribution, where the pioneering contributions are those of Bernardo and Ledoit, and Keating and Shadwick. Finally, the fourth set concerns a few measures that explicitly take into account the investor's utility functions. 相似文献

This study focuses on legacy writing and the development of the life‐history business (e.g., family ghostwriters and writing workshops). A theoretical model is proposed to study the underlying mental processes that lead the elderly to consume such services. This model was empirically tested on a sample of 392 individuals aged from 60 to 92 years. Results highlighted the following: the role of generativity and death preparation reminiscence on identity preservation issues in later life, the strong desire to contribute to collective memories (i.e., to reach people outside of the family circle), and the social nature of the consumption of services that could be considered as a means of sharing emotions. The results of this study will lead to a more in‐depth understanding of consumer behavior regarding the transmission and preservation of the self at end of life, and may also help service providers to improve their products and services. 相似文献

Political polarization expressed through the spatial model of political competition explains the rejection of the Treaty Establishing a Constitution for Europe by French voters. The increasing polarization of the distribution of voters during the last 30 years made the outcome of the 29 May 2005 referendum a predictable event. 相似文献

Following the recent crisis and the revealed weakness of risk management practices, regulators of developed markets have recommended that financial institutions assess model risk. Standard risk measures, such as the value‐at‐risk (VaR), emerged during the 1990s as the industry standard for risk management and become today a key tool for asset allocation. This paper illustrates and estimates model risk, and focuses on the evaluation of its impact on optimal portfolios at various time horizons. Based on a long sample of US data, the paper finds a non‐linear relation between VaR model errors and the horizon that impacts optimal asset allocations. 相似文献
