Dialogues between professionals and their clients are at the core of relationship marketing of professional service firms. To nurture dialogues, professionals need to extend the scope of the dialogue to new issues that impact the client organization's performance. We develop and examine (N?=?431) a model grounded in the theory of planned behavior to highlight factors that impact the willingness of professionals to initiate the extension of client dialogues. Three main results are found. First, affective and instrumental attitudes are distinct and different motivational antecedents that simultaneously impact willingness. Second, affective and instrumental attitude are intermediate psychological considerations shaped by extrinsic rewards, reciprocal relationships, and client relationship quality. Third, organizational pressure operates indirectly by instilling a personal professional norm to extend client dialogues. 相似文献

This article analyses comovements and discusses possibly greater market integration between aggregate food commodity and stock prices in the period 1990 to 2012. Return correlations, price return distributions, cointegration and Granger-causalities are tested in subsamples on monthly FAO Food Price Index and MSCI World Stock Market Index. Empirical results suggest that while there is only weak indication of greater comovements concurrent with structural changes such as changed agricultural policies, new demand due to growth in emerging markets and energy mandates and the financialization of food markets since the early 2000s, they did start to increase substantially in particular during the financial stress of the Lehman crisis and the Great Recession. While structural changes may have amplified price linkages across markets, results do not suggest that they are the key factors for greater price comovements. Instead, the effects of the late-2000s recession as a time of great economic weakness and uncertainty may have changed concurrently the behaviour of both food and financial market participants, such that different market prices exhibit large comovements. 相似文献

The existence of a linear equilibrium in Kyle’s model of market making with multiple, symmetrically informed strategic traders
is implied for any number of strategic traders if the joint distribution of the underlying exogenous random variables is elliptical.
The reverse implication has been shown for the case in which the random variables are independent and have finite second moments.
Here we extend this result to the case in which the underlying random variables are not necessarily independent and their
joint distribution is determined by its moments.

We show that for a spatially differentiated economy reduced product variety is the likely outcome of mergers except in cases where exit costs in relation to (outlet specific) fixed costs are high. Our empirical analysis of the Austrian retail gasoline market confirms that increases in concentration reduce product variety. Ignoring this product variety effect is likely to lead to an underestimate of market power in structural merger analysis. 相似文献

This paper exposes mathematically Charasoff s results on linear production systems. Charasoff developed an algorithm for the iterative calculation of the Leontief inverse, the concepts of basic and non-basic commodities, as well as the Srajfian standard system. This allowed him, given the real wage rate, to calculate the profit rate independently of prices as the ratio of two physically homogeneous magnitudes, and then the prices for an already given profit rate. Therefore, as early as 1910, Charasoff had developed significant concepts of the theory of linear production systems, which long afterwards became more broadly known through the works of Leontief and Sraffa. 相似文献

The environmental company strategy of the case company Oslo Sporveier includes scenarios for the development of person transport in Oslo up to year 2016. The basis for three different scenarios is described. This paper presents the use of scenarios as background for environmental reporting. Emissions, energy, land and time use from person transport in the three different scenarios were determined. The scenarios were (i) a private car scenario, where the main growth in person transport is to be met with a strong increase in the use of private cars, (ii) a public transport scenario, where the increase in person transport is to be taken care of with a strong increase in the public transport, and (iii) the sustainability scenario, with a reduction in total person transport, increased share of public transport and walking/bicycling, and reduced share of private car use. The total energy use, CO2 emissions, NOx emissions and particle emissions from person transport in Oslo are reduced in all three scenarios compared with the situation in 1996. The reduction is smallest in the private car scenario and largest in the sustainability scenario. The land use increases in the private car scenario and the public transport scenario, while there is a reduction in land use in the sustainability scenario. The total time consumption connected to person transport increases in all three scenarios. Copyright © 2004 John Wiley & Sons, Ltd and ERP Environment. 相似文献

We test the assimilation hypothesis, as initially proposed by Chiswick (1978), by making use of a rich panel-data set for Germany, which permits us to allow for unobserved population heterogeneity and potential selectivity bias arising from an individual's remigration decision and employment behaviour. To take into account the institutional aspects of the German guest-worker system we use information on an immigrant's expected duration of stay in Germany to distinguish between temporary and permanent migrants and to test for differences in earnings/experience profiles with respect to a foreigner's expected duration of stay. We find that years of schooling in Germany have a strong positive effect on earnings, that earnings/experience profiles of guest-workers differ by expected duration of stay, and that the renumeration of labour market experience in Germany is higher for natives than for most foreigners. The assimilation hypothesis is therefore not supported by the evidence for Germany. 相似文献
