减少汽车业的浪费

汽车制造商和零件供应商可以节省巨大开支，但前提是双方要更为紧密地合作在一起麦肯锡的研究表明，北美汽车业每年在产品开发和组装过程中由于汽车生产商与供应商缺乏良好的计划和协调不当，造成了超过100亿美元的浪费。事实上．这只是较为保守的估算。因为我们的研究仅涵盖了供应商发生的成本，如：附加设计、生产工具最后改型和零件自身的附加成本。这还不包括因设计问题生产商需额外支付的改型费用、生产问题引发的车辆最终成本的增加或质保支出。这几项每年给汽车行业带来的浪费约为120亿美元。     

Taking a Second Look in a Warped Crystal Ball: Explaining the Accuracy of Revised Forecasts

The fundamental questions we address are whether firms with a higher initial forecasting ability are able to accurately revise the exit forecasts of their investments; and how co‐investment partners and value‐adding commitment with their investment influence the main effect. We explore these questions with novel and unique data collected via mixed research methods on venture capital firms’ forecasts of 114 portfolio companies. We find that venture capital firms that are better at making initial forecasts are less effective in revising their forecasts. In addition, while the number of co‐investment partners positively moderate this relationship, venture capital firms’ value‐adding commitment moderates it negatively. Our findings contribute to the literature on organizational forecasting as well as inter‐organizational knowledge transfer and knowledge creation. They also provide novel insights into venture capital literature and practice.     

Intangible assets and value relevance: Evidence from the Portuguese stock exchange

We assess the value relevance of the amounts for identifiable intangible assets and goodwill reported in the financial statements of all non-finance companies listed on the main market of the Portuguese Stock Exchange from 1998 to 2008. Additionally, we use panel data to explore the impact on value relevance of Portugal’s formal adoption of International Accounting Standards [IAS] and International Financial Reporting Standards [IFRS] in 2005. A distinctive feature of the accounting by our sample companies is that when they adopted IAS 38 and IFRS 3 in 2005, they were no longer required to recognise some intangible assets (such as start-up costs and research expenditures) and were no longer required to amortise goodwill.We find that net earnings, reported goodwill and other intangible assets are highly significantly associated with stock price. However, whereas earnings are related positively to stock prices when Portuguese Generally Accepted Accounting Principles (GAAP) were applied prior to 2005, the value relevance of earnings appears to have declined after the adoption of IAS/IFRS in 2005. Although the change to IAS/IFRS had no impact on the value relevance of identifiable intangibles as a whole, the evidence suggests that there was a positive effect on the value relevance of goodwill. When the subclasses of identifiable intangible assets are considered, we found evidence of an increase in value relevance of goodwill, other intangible assets, and research and development expenditures.     

Do Newspaper JOAs Charge Monopoly Advertising Rates?

Conventional wisdom argues that all commercial and economic competition between two daily newspapers stops when they merge their advertising and printing capabilities to form a joint operating agreement (JOA). Clearly the JOA acts a monopolist in the sale of advertising, but there are two forces that may constrain the JOA to sell more advertising than a profit maximizing single paper monopolist would find optimal. First, there is the possibility of what is sometimes termed ``end game competition'. Disposition of assets from a JOA are often not determined until the JOA is near its termination date, and this may induce the weaker paper to maintain quality, both to improve its bargaining position and to keep open the possibility of remaining in the market as a competitor at the end of the JOA. Second, a daily paper arguably has to maintain a certain level of advertising and maintain a certain ``look' and ``feel' if it is to be considered a daily paper. This may constrain the JOA to sell more advertising and maintain a higher joint circulation than might be optimal for a single paper monopolist. We present econometric evidence that shows JOAs to have ad rates that are closer to those of competitive dailies than to those of single paper and 2-edition monopolists.     

The timing of final charitable bequest decisions

• Understanding the timing of final charitable bequest decisions permits nonprofits to co‐ordinate their marketing efforts to correspond with donor decision‐making. Using probate data from Australia and longitudinal survey data from the USA, this paper seeks to identify the timing of decisions that resulted in realized charitable bequests. We find evidence that charitable transfers result mostly from decisions that occur during the last 5 years of life and at the oldest ages. Charitable plans made earlier in life are often discarded.

Estimating the covariance matrix for regression models with ar(1) errors and lagged dependent variables

We propose a simple procedure, based on an artificial linear regression, for consistently estimating the covariance matrix of the parameter estimates for linear regression models with serially correlated errors and lagged dependent variables.     

Testing the permanent income hypothesis using a general rational lag formulation

This paper estimates a permanent income model of consumption with a constrained moving average error process. Our results do not support the permanent income theory.
