Production-location decision and free entry oligopoly: A correction

This paper shows that there is no interior solution in Mai–Hwang's 1992 oligopolistic location model with free entry when the production function exhibits constant or decreasing returns to scale. The comparative static results of the impact of a demand change on the location decision only apply to the case where the production function exhibits increasing returns to scale. It re-examines the impact of a demand change on the location decision of an oligopolistic firm and corrects the propositions derived by [C.C. Mai, H. Hwang, Production-location decision and free entry oligopoly, Journal of Urban Economics 33 (1992) 252–271. Reprinted in: M.L. Greenhut, G. Norman (Eds.), The Economics of Location, vol. I: Location Theory, Edward Elgar, Aldershot, 1995].     

Optimizing the credit term decisions in supply chain finance

We study a credit term determination problem in the context of a supplier-buyer supply chain. The supplier's credit term decision is simultaneously made with its production and inventory decisions, and most importantly, it is impacted by the buyer's order quantity. We present a new game-theoretic framework to model this problem, which captures the interaction between the supplier's credit term decision and the buyer's order decision in a multi-period setting. An exact method based on nonlinear programming is implemented to obtain the optimal solutions. We apply our methodologies on a real world case. The computational results show that our approach significantly outperforms the heuristics with fixed credit terms, and either a short or a long credit term can be sub-optimal for the supplier in profitability. Our work offers the first data-driven model and solution approach that assists purchasing and supply managers to make optimal dynamic credit term decision in conjunction with production, ordering and inventory decisions in a game-theoretic setting.     

What Causes Banking Crises? An Empirical Investigation for the World Economy

We add the Bernanke-Gertler-Gilchrist model to a world model consisting of the US, the Euro-zone and the Rest of the World in order to explore the causes of the banking crisis. We test the model against linear-detrended data and reestimate it by indirect inference; the resulting model passes the Wald test only on outputs in the two countries. We then extract the model’s implied residuals on unfiltered data to replicate how the model predicts the crisis. Banking shocks worsen the crisis but ‘traditional’ shocks explain the bulk of the crisis; the non-stationarity of the productivity shocks plays a key role. Crises occur when there is a ‘run’ of bad shocks; based on this sample Great Recessions occur on average once every quarter century. Financial shocks on their own, even when extreme, do not cause crises—provided the government acts swiftly to counteract such a shock as happened in this sample.     

Can Management Turnover Restore the Financial Statement Credibility of Restating Firms? Further Evidence

This paper investigates the association between management turnover following financial restatements and the probability of subsequent restatements. We find that restating firms that replace management (CEO and/or CFO) are more likely to restate their financial statements again. We also find that subsequent restatements are mainly attributable to the new management. Overall, our results suggest that management turnover following restatements may not be an effective mechanism to remediate financial restatements, but the change to a new management results in a greater possibility of lower earnings quality (i.e., higher probability of subsequent financial restatements and accruals‐based earnings management). Our study supports prior literature's findings that the change in the top management leads to organizational instability and higher accounting information risk. Our findings have implications for internal decisionmaking with regard to top executive replacement.     

商业银行流动性危机传染机理研究

银行危机传染往往给一个国家或地区的经济带来巨大的损失.不完全的银行间拆借市场中隐含了更大的银行危机传染的可能性;银行间的长期资产越多,银行间拆借的短期利率和银行间存款的长期利率越高,银行间拆借市场就越稳定,在遭受流动性冲击时,这一市场发生银行危机传染的可能性就越小.适量的银行存款对传染效应具有阻碍作用.为防范系统性风险,中国商业银行应逐步建立完备的银行间存款市场,减少政府干预,让市场约束力来强化商业银行的风险管理意识.

The Impact of Sovereign Credit Ratings on Corporations: A Literature Review and Research Recommendations

During the financial crisis, sovereign ratings have come under increased public scrutiny due to their strong impact on sovereign borrowing costs and hence financial stability of countries. However, their influence on corporations within and outside the respective nations has so far attracted only limited attention, although several academics have provided intriguing insights in this regard. In order to obtain a structured overview of this relatively young strand of research, this paper reviews key insights and conclusions that the extant literature offers on the role of sovereign creditworthiness for corporations. Herein, it focuses on the effects that have been observed for the corporate business environment, access to capital, and foreign investment activities. Different research issues providing fertile ground for future studies are identified.
