Is there an ‘interest rate – speculation’ relationship? Evidence from G7 in the pre- and post-2008 crisis

The article revisits the IS-LM macroeconomic model by incorporating speculation into the investment function. The discussion is supported empirically by using data from the G7 countries to examine the different interest rate regimes in the pre- and post-2008 financial crisis. The estimation of an ‘anchor’ interest rate provides a reference rate for the G7 countries. The empirical study is extended to examine if the three quantitative easing (QE) episodes in the U.S. are growth promoting. The article concludes that the maintenance of a high and stable interest rate policy is needed for sustainable growth in the G7 countries.     

股票市场周日历效应传导关系研究

以上证综指、深证成指、恒生指数、日经225指数四种指数为研究对象,实证研究四个股市的周日历效应及其传导关系。研究发现,上证综指在一周中有三天存在周日历效应,周二负效应和周三、周五正效应;深证成指在周三和周五两天存在正效应;恒生指数和日经225指数则分别在周五和周一存在正效应和负效应。上证综指的周三、周五正效应与深证成指的周三、周五正效应互相传导;上证综指与恒生指数的周五正效应互相传导;深证成指与恒生指数的周五正效应亦互相传导;日经225指数与其他三种指数的周日历效应却不存在传导关系。     

宏观经济变量冲击与我国银行间市场风险传染

虽然宏观经济变量对我国银行同业拆借市场的影响比较小,但随着时间的推移,风险传染规模呈扩大趋势,同时银行风险的溢出效应比较明显。本文模型结构和模拟结果显示的四个特征表明,监管当局在防范我国银行风险传染方面不仅要关注宏观经济变量冲击的负面影响和银行在同业拆借市场中的具体交易情况,还需要关注银行风险的传染源和风险溢出效应。监管机构可以通过建立银行偿付水平对应于不同宏观经济变量的敏感系数,时刻关注宏观经济的异常波动对银行偿付能力的影响。

Model uncertainty in Panel Vector Autoregressive models

We develop methods for Bayesian model averaging (BMA) or selection (BMS) in Panel Vector Autoregressions (PVARs). Our approach allows us to select between or average over all possible combinations of restricted PVARs where the restrictions involve interdependencies between and heterogeneities across cross-sectional units. The resulting BMA framework can find a parsimonious PVAR specification, thus dealing with overparameterization concerns. We use these methods in an application involving the euro area sovereign debt crisis and show that our methods perform better than alternatives. Our findings contradict a simple view of the sovereign debt crisis which divides the euro zone into groups of core and peripheral countries and worries about financial contagion within the latter group.

Financial Crisis and Intertemporal Linkages Across the ASEAN-5 Stock Markets

The stock indices of five ASEAN countries, namely, Singapore, Malaysia, Indonesia, Thailand and the Philippines have experienced a structural change after mid-1997 due to the Asian financial crisis, and another shift slightly more than a year later when the markets rebounded. Contemporaneous correlation in stock returns is the strongest and Indonesia leads the movements of the other indices during the crisis. The relative influence of foreign shocks is much more felt during the crisis, as seen in the stronger and longer horizon of responses of all the markets. The stock indices are cointegrated before, but not during the crisis. Price feedbacks between the larger markets of Singapore, Malaysia and Indonesia that existed before the crisis disappear once the crisis is over. Short-run linkages of Malaysia with the other markets have weakened after the crisis. With an increase in the degree of exogeneity of its stock market, contemporaneous co-movements with the other markets have reduced and the causal relationships no longer exist.JEL Classification: G15, F30An earlier draft of this paper was presented at the 11th Annual Conference on Pacific Basin Finance, Economics & Accounting held in Taipei. This paper benefited from the discussions at the conference. We are grateful to two anonymous referees for helpful comments and suggestions which led to further improvement of the paper.     

Crony Capitalism and Sovereign Default

Cronyism provides policymakers with marked incentives to repay sovereign debt. This takes place at the expense of the average citizen who bears both steep costs of debt repudiation and high costs of debt service, as clientelism increases both financial fragility and the debt burden. The paper sets up a model of strategic debt default that nails down this point, with political distortions and where a representative agent can dismiss the government and overrule its decision. Economic hard times provide an opportunity to implement reforms fighting clientelism, as the implicit coalition between groups of cronies may break down. A model is built along these lines, which highlights cross-country contagion of debt repudiation.JEL Classification Numbers: F3, E6, D8     

Do business customers perceive what salespeople believe? Perceptions of salesperson adoption of innovations

A salesperson's commitment and effort toward an innovation can determine whether the customer agrees to buy it, such that customers' perceptions of such commitment and effort are critical. But these perceptions also might differ fundamentally from the salesperson's self-perceptions of commitment and effort. Therefore, this paper presents a theoretical framework of the relation between salesperson-perceived and customer-perceived commitment and effort, as exhibited by the salesperson while selling an innovation, which represents salesperson adoption. In the framework, job satisfaction factors also exert contingent, moderating effects. The authors gather unique, dyadic data from surveys of salespeople and their (potential) business customers during visits to sell a conventional, incremental innovation, complemented by objective purchase data gathered from company records. Three key insights emerge fromt this study. First, salespeople's own perceptions of their commitment and effort have only moderate influences on customers' perceptions of salespeople's commitment and effort. Second, customers seem to recognize salesperson effort more readily than salesperson commitment, although salesperson commitment has a higher sales performance impact than salesperson effort. Thus, sales managers should seek to encourage and support both the commitment of salespeople and also perceptions of that commitment among customers. Third, while a higher organizational support or job autonomy strengthens customers' perceptions of salesperson adoption, a higher pay satisfaction diminishes it. Thus, firms might need to find ways to increase the support for the salespeople and their autonomy and to reduce salespeople's satisfaction with their (direct) payments. In total, these findings suggest significant scientific and managerial implications.
