Hedging,Financing and Investment Decisions: A Simultaneous Equations Framework

We empirically investigate the interactions among hedging, financing, and investment decisions. We argue that the way in which hedging affects a firm's financing and investing decisions differs for firms with different growth opportunities. We find that high growth firms increase their investment, but not leverage, by hedging. However, we also find that firms with few investment opportunities use derivatives to increase their leverage.

Financial integration and the price of world covariance risk: Large- vs. small-cap stocks

We investigate whether recent country-level evidence of global pricing is particular to large-cap stocks. Specifically, we examine cross-country return correlations and conduct asset pricing tests on three size-based stock portfolios for nine developed countries over the period from 1980 to 2004. We find that large-cap stocks realize significant comovements across countries, whereas small-cap stocks realize smaller average correlations (relative to both large-cap stocks and small-cap stocks across countries). More important, asset pricing tests suggest that while large-cap stocks are priced globally, global pricing is rejected for most small-cap stocks. Finally, the evidence indicates that financial integration deepened in recent years primarily for large-cap stocks. Overall, the results suggest that the global pricing pertains chiefly to large-cap stocks.     

Optimum currency areas and the European experience

Across nations or regions, the debate on optimum exchange rate cum monetary policies is not yet resolved on three levels. First is the optimum domain of fixed exchange rates versus keeping them flexible. Second is the subordinate debate on whether one needs full monetary union (as in continental Europe) to secure an optimum currency area's internal domain; or, whether virtually fixed exchange rates — where national currencies remain in circulation — can be sufficient. Third is whether a regional grouping of economies with close trade ties (as in East Asia) gain by collectively pegging to an outside currency such as the US dollar. Using an axiomatic approach, which limits the set of cross‐country financial claims to what is feasible, I analyse how best to both share and reduce macroeconomic risks on these three levels. JEL classification: F31, F36.

From rationality to hyperreality: paradigm poker

This paper, following McGoun's (1997) seminal article comparing the economy of financial securities to a hyperreal poker game, argues that finance and accounting researchers should take the “linguistic turn” that has rejuvenated theory and research in many, if not most, of the social science and humanities in recent decades. In general terms, this means following Ludwig Wittgenstein's language game paradigm rather than Karl Popper's scientific deductive hypothesis testing methodology. The paper illustrates this by drawing on some of Jean Baudrillard's' ideas, particularly his concept of hyperreality and his phases of the image theoretic.The paper presents a poststructuralist genealogical analysis of the radical ruptures and reformulation of the meaning attributed to the accounting sign of earnings over the feudal, counterfeit, production, and simulation eras. It concludes that, as with many other signs in contemporary society, the earnings sign no longer has any relationship with, nor does it any longer refer to, any real or intrinsic profit but instead floats ungrounded in today's financial economy.The paper recommends that researchers in finance and accounting adopt paradigms from literary theory, semiotics, linguistics, and semiology rather than continue to rely on economics-based theory, which has lost its power for explaining and predicting happenings in today's financial economy of self-referencing models and images.     

Thoughts on the Reformation of the Enterprises＇ Financial Concept

Financial concept is the guiding ideology of all kinds of financial behaviors, and it is the foundation of enterprise financial culture. Now, Chinese enterprises have some low-efficiency, none - efficiency and even negative - efficiency financial behaviors. These block the enterprise from developing, and they are due to these none-rational financial concepts. To enhance firm＇s financial efficiency, and promote firm＇s sustainable development, we should set up scientific financial concepts. This paper discusses that scientific financial concepts should include： stakeholder benefits, trustworthy financial concept, green financial concept, risk management conceot and human -orientation, and so on.
