Setting the rules: private power, political underpinnings, and legitimacy in global monetary and financial governance

INTERNATIONAL AFFAIRS, Issue 3 2008
GEOFFREY R. D. UNDERHILL
The role of private market agents in global monetary and financial governance has increased as globalization has proceeded. This shift in both markets and patterns of governance has often been encouraged by states themselves in pursuit of liberalization policies. Much of the literature views these developments in a positive light, yet there are other aspects of these developments that also merit attention. This article supports its central propositions with two cases of emerging global financial governance processes: the Basel II capital adequacy standards for international banking supervision and the International Organization of Securities Commissions-based transnational regulatory processes underpinning the functioning of cross-border securities markets. Based on the case findings, the article argues first that private sector self-regulation and/or public-private partnership in governance processes can leave public authorities vulnerable to dependence on the information and expertise provided by private agents in a fast-moving market environment. Policy in the vital domain of financial regulation has been increasingly aligned to private sector preferences to a degree that should raise fears of bureaucratic capture. Second, the article contends that the overall outcome in terms of global financial system efficiency and stability has been mixed, bringing a range of important benefits but also instability and crisis for many societies to a degree that has led to challenges to global governance itself. The case material indicates that the input, output and accountability phases of legitimacy in global monetary and financial governance are highly problematic, and much of the problem relates to the way in which private market agents are integrated into the decision-making process. Third, the article posits that a better consideration of these three ,phases' of legitimacy and their interrelationships is likely to enhance the political underpinnings and legitimacy of global financial and monetary order.

Volatility dynamics and heterogeneous markets

INTERNATIONAL JOURNAL OF FINANCE & ECONOMICS, Issue 2 2006
David G. McMillan
Abstract Recent research has suggested that intra-day volatility may possess a component structure, resulting either from the arrival of heterogeneous information or the actions of heterogeneous market agents. This paper reports direct evidence for the existence of such components in S&P500 index and DM/$ exchange rate data. Estimation of a FIGARCH model supports the contention that volatility dynamics result from multiple sources. Using a HARCH conditional variance model which defines volatility components over differing time horizons, confirmatory evidence of heterogeneous components is reported, in which context the impact of high-frequency speculation and noise-trading are particularly apparent.

Small producers, supermarkets, and the role of intermediaries in Turkey's fresh fruit and vegetable market

AGRICULTURAL ECONOMICS, Issue 2009
Céline Bignebat
Supermarkets; Small farmers; Fresh fruit and vegetables; Turkey Abstract A wide range of empirical studies show the extent to which the rise of supermarkets in developing countries transforms domestic marketing channels. In many countries, the exclusion of small producers from so-called dynamic marketing channels (that is, remunerative ones) has become a concern. Based on data collected in Turkey in 2007 at the producer and the wholesale market levels, we show that intermediaries are important to understanding the impact of downstream restructuring (supermarkets) on upstream decisions (producers). Results show first that producers are not aware of the final buyer of their produce, because intermediaries hinder the visibility of the marketing channel, thereby restricting a producer's choice to that of the first intermediary. Econometric results show that producers who are indirectly linked to the supermarkets are more sensitive to their requirements in terms of quality and packaging than to the price premia compensating the effort made to meet standards. Therefore, the results lead us to question the role of the wholesale market agents who act as a buffer in the chain and protect small producers from negative shocks, but who stop positive shocks as well, and thereby reduce incentives.

A Markov regime switching approach for hedging stock indices

THE JOURNAL OF FUTURES MARKETS, Issue 7 2004
Amir Alizadeh
In this paper we describe a new approach for determining time-varying minimum variance hedge ratio in stock index futures markets by using Markov Regime Switching (MRS) models. The rationale behind the use of these models stems from the fact that the dynamic relationship between spot and futures returns may be characterized by regime shifts, which, in turn, suggests that by allowing the hedge ratio to be dependent upon the "state of the market," one may obtain more efficient hedge ratios and hence, superior hedging performance compared to other methods in the literature. The performance of the MRS hedge ratios is compared to that of alternative models such as GARCH, Error Correction and OLS in the FTSE 100 and S&P 500 markets. In and out-of-sample tests indicate that MRS hedge ratios outperform the other models in reducing portfolio risk in the FTSE 100 market. In the S&P 500 market the MRS model outperforms the other hedging strategies only within sample. Overall, the results indicate that by using MRS models market agents may be able to increase the performance of their hedges, measured in terms of variance reduction and increase in their utility. © 2004 Wiley Periodicals, Inc.
