The impact of individual and managerial factors on salespeople's contribution to marketing intelligence activities

Although salespersons represent a unique and important channel of information, few of them contribute efficiently to marketing intelligence. This research aims to understand how salespeople's motivation and effort to gather and transmit marketing intelligence to management may be influenced by individual (organizational commitment, desire for upward mobility) and managerial (control system, participation in decision making, feedback, recognition) factors. The test of the proposed model shows that desire for upward mobility is the only individual determinant of behavior. Other than participation in decision making, all the managerial factors play influential roles in structuring both motivation and behavioral effort toward marketing intelligence by salespeople. The authors also discuss the limits of the model, some managerial implications, and future research opportunities.     

A never-decisive and anonymous criterion for optimal growth models

We address in this paper the question of the existence of a Social Welfare Function that would be sustainable and would allow us to obtain solutions to optimal growth models. We define sustainability by two new axioms called Never-decisiveness of the present and Never-decisiveness of the future. We first show that a SWF which has Never-decisiveness properties cannot be defined on a ball of $l_{\infty }^{+}$ . We must (i) restrict to the set of utility streams for which the value of the SWF is finite and (ii) introduce additional assumptions in order to obtain the Never-decisiveness properties. Our main result in this paper is therefore to show that the undiscounted utilitarian criterion is an anonymous and never-decisive criterion for optimal growth models. We consider the set of utilities of consumptions which are generated by a specific technology, namely a technology with decreasing returns for high levels of capital, and restrict ourselves to good programs, i.e., any program for which intertemporal utility is well defined.     

Preservation and exogenous uncertain future preferences

Summary. We extend the Beltratti, Chichilnisky and Heal's (1993) and (1998) continuous-time stochastic dynamic framework to analyze the optimal depletion of an asset whose consumption is irreversible, in the face of uncertainty about future preferences. Their model is rather general and so the results are general qualitative theorems. We show that in some interesting cases it is possible to solve their model analytically. The cases involve constant elasticity utility functions and the assumption of a Poisson process for the evolution of preferences.

市场经济的伦理缺陷研究

市场经济的伦理缺陷:首先,表现在市场经济基本理念与传统道德价值与原则的根本冲突;其次,表现在市场经济运行过程对经济原则的片面坚持与对伦理价值的顽固排斥与否定。克服市场经济伦理缺陷的根本办法在于重新审视经济理性的合理性,检讨经济发展的终极意义,使市场经济以及经济理性回复到在伦理规则指引下为人类主体性生存服务的合理轨道上来。     

TRADE LIBERALIZATION AND GROWTH: Evidence from Mexican Cities

Applying the most recent methodology for explaining economic growth differences across countries (Barro, 1997), education, learning by doing, infrastructure, and knowledge spillovers due to specialization have been considered relevant in explaining productivity growth differences in Mexican urban manufacturing (de León, 1999). In this article, I evaluated whether there is a significant change in the relevance of these variables under trade liberalization. In particular, I evaluated the hypothesis that trade liberalization would promote productivity growth in the northern cities as result of the dynamic effect of trade given that these cities are close to the new central market for Mexican manufacturing and the loss of relevance in the previous accumulated growth factors (Livas and Krugman, 1992; Hanson, 1994). In contrast to that hypothesis, I observed that urban manufacturing close to the United States did not show a better performance than the rest of the cities as expected and that accumulated growth factors, such as education, learning by doing, and infrastructure are still relevant in explaining productivity growth across urban manufacturing in Mexico.     

我国国际资本流入结构的变化:2001—2008

我国加入世界贸易组织以来，流入我国的国际资本结构发生了较大的变化。从资本数量结构来看，资本总量逐年增加，外商直接投资比重下降，间接投资的比重上升；从资本期限结构来说，短期资本总量超过长期资本总量，中长期债务余额比较稳定，而短期债务增速较快，贸易信贷比重逐年增加；国际资本主要来源地没有大的变化；国际资本流入的行业结构中，虽制造业仍占据较大的比重，但服务业所吸收的外资却快速增长，占比越来越大。
