The conventional dividend–price ratio is highly persistent, and the literature reports mixed evidence on its role in predicting stock returns. We argue that the decreasing number of firms with a traditional dividend‐payout policy is responsible for these results, and develop a model in which the long‐run relationship between the dividends and stock price is time varying. An adjusted dividend–price ratio that accounts for the time‐varying long‐run relationship is considerably less persistent. Furthermore, the predictive regression model that employs the adjusted dividend–price ratio as a regressor outperforms the random‐walk model. These results are robust with respect to the firm size.  相似文献

This case illustrates the effects of the proposed new lease standard by the Financial Accounting Standards Board and the International Accounting Standards Board on existing outstanding operating leases. Specifically, the case examines the effects of the proposal that all firms report existing operating leases as capital leases upon the initial adoption of the proposed standard. By applying a constructive capitalization model to two firms who rely on operating leases for financing, FedEx and UPS, we found that both companies would have to record billions of dollars of liabilities that had only appeared in the footnotes of their financial statements under the current lease standards. In addition, the firms would experience a decline in retained earnings and key financial ratios, such as the debt‐to‐equity, return‐on‐assets, and interest coverage ratios, by reporting operating leases as capital leases under the new proposed standard. Furthermore, the magnitude of the lease capitalization impact is much smaller for UPS than for FedEx.  相似文献

A new product originates from an idea, or in many cases, integration of multiple ideas. The process of transforming an idea into a robust concept requires definition of the underlying technologies, identification of expected customer benefits, and assessment of the market opportunity. The idea-development and subsequent idea-selection stages of new product development are often referred to as the "fuzzy front end" because they typically involve ad hoc decisions and ill-defined processes. To address this shortcoming, Nortel developed an idea-to-opportunity front-end process that provides a consistent and structured approach for idea development and evaluation. This article describes the process and how it was implemented using electronic performance support technology.  相似文献

The aim of this paper is to propose an integrative framework for understanding the determinants of business strategies to reduce greenhouse gas emissions and the impact of these determinants on performance. The proposed structural equation model is based on a survey of 319 Canadian manufacturing firms. The study calls into question the traditionally positive relationship between a firm's environmental commitment and its economic motivations. However, the results also show a win–win relationship between the commitment to reduce greenhouse gas emissions and financial performance. This study contributes to the understanding of the motivations underlying the efforts manufacturers make to tackle climate change and their economic benefits.

Previous studies have shown that regulated firms diversify for reasons that are different than for unregulated firms. We explore some of these differences by providing a theoretical model that starts by considering the firm–regulator relationship as an incomplete information issue, in which a regulated incumbent has knowledge that the regulator does not have, but the firm cannot convey hard information about this knowledge. The incumbent faces both market and nonmarket competition from a new entrant. In that context, we show that when the firm faces tough nonmarket competition domestically, going abroad can create a mechanism that makes information transmission to the regulator more credible. International expansion can thus be a way to solve domestic nonmarket issues in addition to being a catalyst for growth. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献

Drawing on the contextual perspective, this study provides novel empirical evidence on how the organisational context (specifically, the firm's human resource strategy) has an effect on employee proactivity. We use matched data from managers and employees in 102 Spanish professional service firms to examine how high performance work systems contribute to enhance employee proactive behaviours through two motivational variables: role breadth self‐efficacy and flexible role orientation. Results of a multilevel study demonstrate that role breadth self‐efficacy mediates between HPWS and employee proactivity, but flexible role orientation does not mediate this relationship.  相似文献

This paper applies the DSGE‐VAR methodology to assess the size of fiscal multipliers in the data and the relative contributions of two transmission mechanisms of government spending shocks, namely hand‐to‐mouth consumers and Edgeworth complementarity. Econometric experiments show that a DSGE model with Edgeworth complementarity is a better representation of the transmission mechanism of fiscal policy as it yields dynamic responses close to those obtained with the flexible DSGE‐VAR model (i.e. an impact output multiplier larger than one and a crowding‐in of private consumption). The estimated share of hand‐to‐mouth consumers is too small to replicate the positive response of private consumption. Copyright © 2016 John Wiley & Sons, Ltd.  相似文献

This paper explores the factors influencing the board composition of an international sample of commercial banks over the period 1996–2006. After considering the dual role of the board as monitor and advisor, our analysis shows that no one board composition is optimal for the banking industry and that any such recommendation could harm bank governance. Our results suggest that more complex banks that have a low ownership concentration and are headquartered in a civil law country should have larger and more independent boards.

This article develops a dynamic model to investigate renewable resource markets under different property rights. We find that different property rights regimes in renewable resource markets yield very different equilibria. Under private property rights, the valve point increases with the natural growth rate, productivity, number of firms, and marginal costs. Under common property rights, “the tragedy of the commons” inescapably occurs. This study suggests how to avoid ecological disaster by implementing a set of public policies.  相似文献
