IMMEDIATE SETTLEMENT OR ENDURING A STRIKE: THE CHOICE OF SIGNALS

Some labour contract negotiations involve strikes while most conclude with immediate settlement. This article offers a model of union‐firm negotiation with private information to show that either strikes or immediate settlement will take place in the equilibrium. Different from most signalling literature where the signals are exogenously given, this article endogenizes the choice of signals. We compare two signals, the employment level and the strategic delay. We show that the low‐revenue firm will choose the signal which gives it higher payoff while separating itself from the high‐revenue firm.     

Regulation of relationships between heterogeneous farmers and an aquifer accounting for lag effects

Many environmental problems are due to damage caused by pollutants that accumulate with a time lag following their emission. In this study, we focus on nitrates used in agriculture, which can pollute groundwater many years after their initial application. A dynamic optimal control problem with heterogeneous farmers is proposed. The usual structural parameters such as the discount rate, the natural clearing rate and the lagged time interval between the occurrence of soil‐level pollution and the impact on groundwater are taken into account. We also examine pollution as caused by a continuous set of farms characterised by their individual performance index and by their individual marginal contribution to the pollution. The issue is further investigated by taking account of change in the information context, successively related to perfect information and to asymmetric information. As a result, when the delay between the spreading of N‐fertilizer and the impact on the aquifer increases, that is, the longer the lag, the steady‐state pollution stock and the steady‐state shadow price of the stock both increase. Moreover, we show that the optimal regulation may require a decreasing amount of fertilizer over time, even in the case of initial underpollution.     

导游实践中的跨文化交流

导游员是旅游业的灵魂,在旅游产品转化为旅游消费的过程起着至关重要的作用。由于游客来源与背景等文化差异,这一转化过程受到不同文化因素的制约,而跨文化交流意识的养成与跨文化交流技巧的运用是使这一转化顺利实现必不可少的一种手段。在导游实践中,合理运用跨文化交流知识与技巧,将有助于实现旅游产业的最优化,促进和谐的导游与游客的关系。

社会互动、相对财富关注及股市参与

已有的研究表明,社会互动推动了家庭的股市参与。依据社会互动推动家庭股市参与不同机制的理论基础和预测,本文对不同的具体机制进行了研究,我们发现在局部品支出比例高、收入分布集中度高的区(村),社会互动推动股市参与的作用更显著,这与外部习惯模型及相对财富关注模型的理论预测一致,事前对局部稀缺品的关注使得家庭的股市参与存在外部性。社会互动推动股市参与其他机制的理论预测则未得到数据的支持。     

Product Market Competition,Managerial Incentives and Firm Valuation

This paper contributes to the very small empirical literature on the effects of competition on managerial incentive schemes. Based on a theoretical model that incorporates both strategic interaction between firms and a principal agent relationship, we analyse the relationship between product market competition, incentive schemes and firm valuation. The model predicts a nonlinear relationship between the intensity of product market competition and the strength of managerial incentives. We test the implications of our model empirically based on a unique and hand‐collected dataset comprising over 600 observations on 200 Swiss firms over the 2002–2005 period. Our results suggest that, consistent with the implications of our model, the relation between product market competition and managerial intensive schemes is convex indicating that above a certain level of intensity in product market competition, the marginal effect of competition on the strength of the incentive schemes increases in the level of competition. Moreover, competition is associated with lower firm values. These results are robust to accounting for a potential endogeneity of managerial incentives and firm value in a simultaneous equations framework.

城镇化与工业化互动发展的协调性与驱动力研究——来自四川省21个市州的经验证据

城镇化与工业化互动协调发展是城乡经济发展的一个主要问题。在构建新型城镇化和新型工业化评价指标体系的基础上,采用四川省21个市州2007—2012年相关数据,运用“协调度—协调发展度模型”和灰色系统模型 GM（1,N）,对城镇化与工业化互动发展的协调性进行评价,并揭示其内在驱动力,结果表明：四川省城镇化与工业化互动发展的协调度与协调发展度处于不断提高的过程中,21个市州工业化发展对城镇化与工业化互动协调发展均起着促进作用,但经济发展水平极高和极低市州的城镇化发展对城镇化与工业化互动协调发展具有制约作用。因此,应以工业化带动城镇化发展,制定差别化的城镇化与工业化互动发展政策,全面深化制度改革,形成城镇化与工业化互动协调发展的良性机制。
