SEARCHING FOR ENDOGENOUS BUSINESS CYCLES IN THE U.S. POSTWAR ECONOMY

This paper explores the possibility that booms and busts are endogenous with an econometric examination of the U.S. economy. Although existing empirical results suggest the contrary, a theoretical literature discounts the stability verdict on the grounds that it is based on linear econometric evidence which is unreliable when the underlying phenomenon is non-linear. We study a simple Keynesian cycle model which is theoretically general enough to include convergence to equilibrium or endogenous cycles as special cases. We find one particular nonlinear econometric specification which exhibits a limit cycle when estimated on postwar data, while the estimate of its global linear approximation converges to a fixed equilibrium. Our results are an empirical investigation of the boundary between stability and instability.     

Monetary,Financial and Fiscal Stability in the East African Community: Ready for a Monetary Union?

We examine prospects for a monetary union in the East African Community (EAC) by developing a stylised model of policymakers' decision problem that allows for uncertain benefits derived from monetary, financial and fiscal stability and then calibrating the model for the EAC for the period 2003–10. When policymakers properly allow for uncertainty, none of the countries wants to pursue a monetary union based on either monetary or financial stability grounds, and only Rwanda might favour it on fiscal stability grounds; we argue that robust institutional arrangements assuring substantial improvements in monetary, financial and fiscal stability are needed to compensate.     

As time goes by: Examining the paradox of stability and change in business networks

Stability and change may seem contradictory features but in business networks, they coexist [Hakansson H, Snehota, I. Developing Relationships in Business Networks. London, Routledge; 1995]. This article explores the paradox of the coexistence of stability and change in an Australian context. Previous research illustrated that stability over time can exist in specific business relationships [Sutton-Brady C, Donnan, M. Nexus nonsense or is it? Conference Proceedings, 19th Annual IMP Conference, Lugano, Switzerland September 2003; 2003]. This research study further investigates time as a proxy variable of stability [Halinen A, Tornroos, J-A. The meaning of time in the study of industrial buyer–seller relationships. In: Moller K, Wilson DT, editors. Business Marketing: An Interaction Approach. Norwell, Mass: Kluwer Academic Publishers; 1995.] and attempts to uncover other variables, which may influence the stability of the relationship. Given the exploratory nature of the research a case study approach was utilized to gain an in-depth understanding of the variables, which may contribute to the stability. This article further advances the concept of time as a proxy variable for stability while investigating what other variables may be crucial in understanding this concept. From analysis of the case studies, the findings show that other variables do play a role in determining the stability and change in the relationships and networks, these included location, product/service quality, technology, cooperativeness, adaptations and cost. The major contribution of this article is the reopening of discussions on time as a proxy variable for stability and attempts to broaden this to include other variables.     

Matrix Representation of Conflict Resolution in Multiple-Decision-Maker Graph Models with Preference Uncertainty

Explicit matrix representations of solution concepts in a graph model of a multiple-decision-maker conflict with preference uncertainty are developed. In a graph model, the relative preferences of each DM over the available states are crucial in determining which states are stable according to any stability definition (solution concept). Unfortunately, it is often difficult to obtain accurate preference information in practical cases, so models that allow preference uncertainty can be very useful. In this work, stability definitions are extended to apply to graph models with this feature. The extension is easiest to implement using the matrix representation of a conflict model, which was developed to ease the coding of logically-defined stability definitions. Another benefit of matrix representation is that it facilitates modification and extension of the definitions.     

Thoughts about Monetary and Fiscal Policy in a Postinflation World

There is a cultural lag in economic policy, particularly when it comes to inflation. Should inflation continue to be a concern, or is the new “normal” one in which inflation is low on the list of threats? In particular, central banks should focus on their original mission of ensuring financial stability and recognize that monetary accommodation is likely to continue to be appropriate. Budget policy, too, must play a role in promoting economic health—but expenditures should be shifted toward investment that increases productivity rather than consumption. Also, the federal tax codes and entitlements should be restructured so that they promote rather than impede growth. Finally, it is important to guard against institutions and individuals that have enormous financial power using that power to gain short-run advantage for themselves at the expense of long-term stability and prosperity for all.     

基于成本收益视角的我国显性存款保险制度有效性分析

银行体系的稳定是金融稳定的核心。我国一直实行的是隐性存款保险制度,由于其隔断了各银行资金运用收益和资金筹集成本之间的制衡关系,使政府实施这种制度的成本越来越高。本文从显性存款保险制度与隐性存款保险制度的比较分析入手,基于成本和收益的视角,指出引入显性存款保险制度的最大成本在于其引致了新的道德风险问题,而且我国的制度环境薄弱加大了建立成本。在此基础上本文对建立我国显性存款保险制度的有效性进行论述,并提出一系列配套改革措施。     

Diversification,efficiency and risk of banks: Evidence from emerging economies

This paper examines the impact of business diversification of banks on their risk, with efficiency taken into consideration as a conduit. Using bank-level data from more than 1000 commercial banks in 39 emerging economies during the period of 2000–2016, we find that increased business diversification exerts two competing effects on bank risk. The direct effect of increased diversification bolsters the stability of banks, but it is offset by the indirect effect whereby lowered efficiency, which is resulted from higher diversification, increases the riskiness of banks. Thus, the overall benefits from bank business diversification on bank stability rely on the trade-off of the two competing forces.     

What Have I Done to Deserve This? Effects of Employee Personality and Emotion on Abusive Supervision

Drawing on victim precipitation theory, we propose that certain employees are more likely to perceive abusive supervision because of their personality traits. Specifically, we hypothesize that subordinates’ emotional stability, conscientiousness, and agreeableness will be negatively related to perceived abuse from their supervisor and that negative emotions at work will mediate these relationships. We surveyed 222 employees and found that emotional stability and conscientiousness negatively predicted employees’ self-reports of abusive supervision and that this relationship was mediated by negative emotions. Thus, employees lower in emotional stability or conscientiousness are more likely to experience negative emotions, which in turn is related to higher levels of abuse.     

The natural environment as a salient stakeholder: non-anthropocentrism, ecosystem stability and the financial markets

The current debate as to whether the natural environment should be accorded stakeholder status involves an assumption that it is in some way 'different' from other stakeholders, requiring favourable discriminatory treatment. Essentially it is regarded as passive, requiring regulatory agencies to represent its interests or the wider public to demand its protection on the occasion of, for example, oil spills that leave wildlife in a visibly distressed state. But the natural environment does not have 'consciousness' as do traditional classes of stakeholders such as employees, shareholders and contractors, nor does it negotiate in markets over the price at which it sells its output in the way that a trader haggles with potential buyers. This paper proposes that in the context of financial markets the natural environment possesses stakeholder status, founded upon the essentiality of ecosystem stability for their proper functioning and the structuring of instruments traded on them.     

The role of elasticity optimism in choosing an optimal currency basket with applications to Israel

In a world in which exchange rates are floating each country must have some device for measuring the average exchange rate change, whatever exchange rate policy it chooses. The weight for each currency in computing such an average depends on the objective which exchange rate stabilization, or change, is expected to achieve. If balance of trade stability is the desideratum, the optimum weights (optimum currency basket) are shown to be a function of demand elasticities, GNP, trade shares, etc. We derive a loss function measuring the cost of using a ‘wrong’ basket, and compute the value of this function for our ‘optimal’ Israeli basket as a case study.
