OPTIMAL MONETARY POLICY WITH THE STICKY INFORMATION MODEL OF PRICE ADJUSTMENT: INFLATION OR PRICE‐LEVEL TARGETING?

I investigate the optimal monetary policy in a New Keynesian macroeconomic framework with the sticky information model of price adjustment. The model is solved for optimal policy, and welfare implications of three alternative monetary policy regimes under this optimal policy are compared when there is a cost‐push shock to the economy. These monetary policy regimes are the unconstrained policy, price‐level targeting and inflation targeting regimes. The results illustrate that optimal policy depends on the degree of price stickiness and the persistence of the shock. Inflation targeting emerges as the optimal policy if prices are flexible enough or the shock is persistent enough. However, the unconstrained policy or price‐level targeting might be preferable to inflation targeting if prices are not very flexible and the shock is not very persistent. The results also show that as prices become more flexible, the welfare loss usually gets bigger.     

公允价值会计的反思

公允价值与历史成本之间的孰优孰劣一直就伴随着争议。我们不应该忽视公允价值固有的内涵缺陷及其与财务会计概念框架的冲突,以及在金融危机中的顺周期效应。文章将从会计决策有用目标和会计信息质量以及准则的经济后果角度重新反思公允价值会计。     

Bank loan announcements and borrower stock returns before and during the recent financial crisis

The impact of U.S. bank loan announcements on the stock prices of the corporate borrowers has been decreasing during the two last decades with estimated two-day cumulative abnormal returns slipping from almost 200 basis points in the beginning of the 1980s to close to zero by the turn of the Century. We estimate excess returns before and after the onset of the most recent financial crisis. We find that while prior to August 2007 returns were indeed close to zero, afterwards returns jump back up to around 200 basis points. We surmise that in a booming credit market the certification of corporate borrowers by banks started to play a lesser role, while during the crisis the banks’ role was revitalized. Consistent with this interpretation we find that after August 2007 excess returns increase especially for loans with a longer maturity, and for smaller, levered, less profitable or lowly rated firms.

Open-Market Stock Repurchase and Stock Price Behavior When Management Values Real Investment

This paper provides a simple explanation of open‐market stock repurchases and the stock price behavior surrounding them. There is ex ante asymmetry of information with regard to the private benefits that corporate managers can attain from real investments. In our model, open‐market repurchase announcements reveal information about the managers' private benefits when real investment opportunities are unprofitable in terms of firm values. This study differs from previous studies in that we show that announcements of open‐market repurchase programs can be believable without the restriction that the announcements are commitments. Empirically, the model simultaneously predicts that a stock price will drop prior to an open‐market repurchase announcement and will rise in response to the announcement. These predictions are consistent with stylized facts.     

会计信息真实性的法律保证

会计信息是经济信息中的重要组成部分，它的真实性决定着宏观和微观经济决策的正确性和准确性，直接影响到国家的经济发展和在国际经济交往中的形象。但长期以来，一些地方政府和企业的领导受利益驱动，提供虚假会计信息，导致会计造假现象十分严重。假数字、假报表充斥着我们经济生活的方方面面，会计打假势在必行。新《会计法》的颁布实施为规范会计行为，净化经济环境，保证会计信息的真实性提供了有力的法律保证。     

The Transmission of Pricing Information of Dually-Listed Stocks

We use the daily opening and closing prices of eighteen dually-listed Hong Kong companies to investigate the transfer of pricing information between the Stock Exchange of Hong Kong (SEHK) and the London Stock Exchange (LSE). Evidence shows that (1) SEHK overnight returns respond significantly to change in LSE intraday returns, but the transmission process is not completed at the opening of the SEHK; (2) LSE overnight returns respond significantly to changes in SEHK intraday returns, but the transmission process is not completed at the opening of the LSE, either; (3) the impact is stronger moving from the LSE to the SEHK. This evidence indicates that information transfer runs in both directions and that most of the transmitted information continues to be processed throughout the following trading day (JEL G15).
