Using time-series cross-section data from the manufacturing sector of the 11 West German 'Bundesländer' (Federal States) from 1970 to 1996, I examine the impact of public capital on private production. My econometric analysis explicitly takes into account four of the most frequent specification issues in the context of time-series crosssection data analysis: serial correlation, groupwise heteroscedasticity, cross-sectional correlation and non-stationarity of data. For all approaches and tested specifications, I find that public capital is a significant input for production in the manufacturing sector. Moreover, I find that differences in public capital endowment can explain long-term differences in productivity across the Bundesländer. One tentative conclusion that can be drawn from this finding is that differences in public capital endowment might also explain a part of the still-existing productivity gap between manufacturing in East and West Germany. However, I emphasise that the existence of positive effects of public capital on private production is a necessary, but not a sufficient condition for concluding that public investments should be boosted in the future.  相似文献

We determine when an unfettered auction will ensure the welfare‐maximizing allocation of a scarce input that enhances product quality and may reduce production costs. A supplier values the input for this “use value” and for its “foreclosure value,” because once the input is acquired, it is unavailable to rivals. An unfettered auction often ensures the welfare‐maximizing allocation of an input increment. However, it can fail to do so when the input would increase relatively rapidly the competitive position of a rival with a moderate competitive disadvantage. Bidder handicapping that ensures auctions generate welfare‐maximizing input allocations differ from standard handicapping policies.  相似文献

The results of this study indicated that consumers had a favorable attitude toward advertising by lawyers, though some specific differences were found between users and nonusers of legal services. The importance of consumer demographic characteristics and the appropriateness of advertising media were also examined. The major implication is that the traditional void in advertising activity by lawyers should now be reexamined.  相似文献

In the western world, and in the United States in particular, there has been an abundance of food, materials and fuel over the past several decades. However, many futurists suggest this condition will soon change and a wide range of scarcities will result. Conditions in underdeveloped countries suggest one probable reaction to shortages in hoarding. In light of the predicted shortages this paper (1) develops definition and conceptualization of what constitutes hoarding, and (2) examines the influence hoarding activities have on channel decisions. An overriding purpose of the paper is to generate interest and research into the topic before conditions necessitate that concern.  相似文献

This paper analyses the presence of financial constraint in the investment decisions of 367 Brazilian firms from 1997 to 2004, using a Bayesian econometric model with group-varying parameters. The motivation for this paper is the use of clustering techniques to group firms in a totally endogenous form. In order to classify the firms we used a hybrid clustering method, that is, hierarchical and non-hierarchical clustering techniques jointly. To estimate the parameters a Bayesian approach was considered. Prior distributions were assumed for the parameters, classifying the model in random or fixed effects. Ordinate predictive density criterion was used to select the model providing a better prediction. We tested thirty models and the better prediction considers the presence of 2 groups in the sample, assuming the fixed effect model with a Student t distribution with 20 degrees of freedom for the error. The results indicate robustness in the identification of financial constraint when the firms are classified by the clustering techniques.  相似文献

This paper explores the issue of sustainability at the macro scale employing multi-criteria decision aid (MCDA) methods. The incommensurability of values and the essentially multi-dimensional and dynamic nature of sustainability challenge the use of composite measurement indices. This determined the choice of MCDA methods. Austria was chosen as a case study, due to the wide availability of data, especially on indicators of strong sustainability. The structure of the multi-criteria problem comprised the evolution of different sustainability dimensions over time. The process for selecting criteria included a critical assessment of institutional sustainability agendas (UN, EU and Austrian Government) and theoretical recommendations.After an assessment of MCDA methods, the NAIADE method demonstrated the most suitable properties for sustainability assessment. The application of this outranking approach was undertaken in three separate settings: long-term from 1960 to 2003, medium-term, 1970-1995, and short-term, 1995-2003 with varying numbers of criteria. The response of results to the addition of evaluating criteria and periods was tested. The degree of credibility for accepting preference relations was also employed for sensitivity analysis.According to the results of long-term and medium-term assessments, especially in the weak sustainability setting, sustainable progress is taking place in Austria. In the short term, in the stronger sustainability setting and, especially as the number of criteria increases, more incomparable periods appear and trends are less determined. Moreover, it is shown how results crucially depend on the methodological choices.This is one of the first applications of the multi-criteria tools to the dynamic analysis of sustainability at the macro scale.  相似文献

Contrary to the popular belief, specialization is not necessary for gravity equations. This paper shows that the simple gravity equation holds if and only if the market share of an exporting country is constant across all importing countries. Specialization is just one special case satisfying this condition. The constant‐share condition can hold in a variety of situations where multiple producers compete with a homogeneous good. Further, this paper shows that the ratio of bilateral trade to the product of partner incomes is increasing in the extent of specialization and in the intensity of intra‐industry trade. Since the relationship is not model‐specific, the correlations among these variables do not support any specific model.  相似文献
