Equity compensation and the sensitivity of research and development to financial market frictions

When financial market frictions exist, executives may have to decide which investment activities to reduce when internal funds decrease. Expenditures on research and development (R&D) may be particularly vulnerable because of the long-term nature of innovative activity. We find that equity compensation is associated with lower levels of firm R&D expenditures. Rewarding executives to incur more risk has little effect on R&D expenditures, but rewarding executives for higher returns reduces R&D expenditures and makes R&D expenditures more sensitive to financial market frictions. In contrast, cash compensation reduces the sensitivity of R&D expenditures to financial market frictions.     

Pot of gold or winner's curse? An event study of the auctions of 3G mobile telephone licences in the UK

Commentators have suggested that the winning companies in the UK 3G mobile telephone auction overpaid for their licences. However, event‐study method using the market model under ordinary least squares (OLS), robust and structural time‐series estimation yields no systematic evidence of the ‘winner's curse’. Positive as well as negative one‐day wealth effects are observed amongst both winners and losers, and there is no lasting adverse market reaction to the winners, taken as a group. We conclude there is no case for easing the regulatory stance in the industry on grounds that the winners paid too much.

A corporate governance explanation of the A-B share discount in China

B-shares listed in China are traded at substantial discounts to their corresponding A-shares although they have identical rights. We offer a governance explanation and suggest that relative to domestic investors, foreign investors care more about a firm’s governance quality. Results are supportive, as the B-share price discount is higher for firms that have weaker governance characterized by 1) higher ownership concentration, 2) ineffective boards with a higher proportion of directors appointed by the parent company, 3) lower dividend payouts, and 4) higher levels of information asymmetry.     

The G4's role in the evolution of the international accounting standard setting process and partnership with the IASB

Between 1992 and 2001, representatives of the G4 national accounting standard setting bodies and the International Accounting Standards Committee (IASC) participated in a working group known as the G4+1. Immediately following the formation of the International Accounting Standards Board (IASB), the G4 announced that the working group would no longer meet. Alternatively, the G4 national standard setters would form a partnership with the IASB via liaison representatives.This paper focuses on the objectives and mission of the G4+1, the G4's relationship with the IASC, the impact of the G4 on the restructuring of the IASC to establish a quality independent global accounting standard setter, former G4 participants’ perceptions of the IASB, and the significance of the IASB's current partnership with the G4 national accounting standard setters. The paper additionally discusses recent changes to the IASC Foundation Constitution and considers now modifications to the liaison structure may impact the IASB's partnership with its G4 national standard setting partners.Portions of a monograph published by the Institute of Chartered Accountants in England and Wales entitled Inside G4+1: The Working Group's Role in the Evolution of the International Accounting Standard Setting Process provide the background for the paper.     

Evidence on the role of accounting conservatism in monitoring managers’ investment decisions

Watts (2003), among others, argues that conservatism helps in corporate governance by mitigating agency problems associated with managers’ investment decisions. We hypothesize that if conservatism reduces managers’ex ante incentives to take on negative net present value projects and improves the ex post monitoring of investments, firms with more conservative accounting ought to have higher future profitability and lower likelihood (and magnitude) of future special items charges. Consistent with this expectation, we find that firms with more conservative accounting have (i) higher future cash flows and gross margins and (ii) lower likelihood and magnitude of special items charges than firms with less conservative accounting.     

Bailout uncertainty in a microfounded general equilibrium model of the financial system

This paper develops a micro-founded general equilibrium model of the financial system composed of ultimate borrowers, ultimate lenders and financial intermediaries. The model is used to investigate the impact of uncertainty about the likelihood of governmental bailouts on leverage, interest rates, the volume of defaults and the real economy. The distinction between risk and uncertainty is implemented by applying the multiple priors framework to beliefs about the probability of bailout.Results of the analysis include: (i) An unanticipated increase in bailout uncertainty raises interest rates, the volume of defaults in both the real and financial sectors and may lead to a total drying up of credit markets. (ii) Lower exante bailout uncertainty is conducive to higher leverage, which in turn raises moral hazard and makes the economy more vulnerable to expost increases in bailout uncertainty. (iii) Bailout uncertainty affects the likelihood of bubbles, the amplitude of booms and busts as well as the banking and the credit spreads. (iv) Higher bailout uncertainty is associated with higher returns’ variability in diversified portfolios and higher systemic risks, (v) Pre-crisis expansionary monetary policy reinforces those effects by inducing higher aggregate leverage levels. (vi) The larger the change in bailout uncertainty and the change in aversion to this uncertainty, the stronger the pre-crisis buildup and the deeper the ensuing crisis.A central policy implication of the analysis is that the vaguest is bailout policy prior to a crisis, the lower is the magnitude of investments destroyed or missed due to errors in evaluating bailout and other intervention policies. On the other hand, the clearer is bailout policy upon the eruption of a crisis, the smaller the contraction of credit and the destruction of investment activity.     

Changes in the value relevance of goodwill accounting following the adoption of IFRS 3

This study examines the value relevance effects of changes in goodwill accounting in a European setting. International Financial Reporting Standard (IFRS) 3 replaced accounting rules that emphasized goodwill amortization over short useful lives which kept goodwill balances low. Goodwill accounting under IFRS 3 largely relies on manager fair value estimates of acquired business units. Using Swedish data, we show that goodwill amortizations were not value-relevant prior to the adoption of IFRS 3. However, impairments reported in addition to amortization were significantly related to stock returns during that period. In contrast, under the impairment-only regime prescribed by IFRS 3, impairments are no longer statistically related to stock returns.
