We present CoMargin, a new methodology to estimate collateral requirements in derivatives central counterparties (CCPs). CoMargin depends on both the tail risk of a given market participant and its interdependence with other participants. Our approach internalizes trading externalities and enhances the stability of CCPs, thus, reducing systemic risk concerns. We assess our methodology using proprietary data from the Canadian Derivatives Clearing Corporation that includes daily observations of the actual trading positions of all of its members from 2003 to 2011. We show that CoMargin outperforms existing margining systems by stabilizing the probability and minimizing the shortfall of simultaneous margin-exceeding losses

This paper focuses on the unique Danish setting in examining the consequences of abandoning a mandatory joint audit regime. We study the effects on audit costs (measured by audit fees) and audit quality (measured by abnormal accruals) of the abandonment of the mandatory joint audit in Denmark in 2005. We perform our analysis on non-financial listed Danish companies for the 2002–2010 period. Our results show that a joint audit is associated with higher fees, but that the association between joint audit and abnormal accruals is insignificant. This suggests that the higher audit fees cannot be explained by higher audit quality. Our results are robust to alternative measurements of fees and audit quality. Additional analyses show that the fee premium related to a joint audit decreases over time and that the Big 4 concentration in our sample has increased since the switch from mandatory to voluntary joint audit. Our results are consistent with the motivations driving the regulatory change in Denmark and are of interest to regulators and actors in the audit market

Constructing, Contesting, and Overloading: A Study of Risk Management Framing

In this study, we examine the ways in which actuarial consultants attempt to motivate their clients to see pension-related accounting regulations and market volatility as ‘risks’ that need to be managed through particular risk-mitigating technologies. This study is predicated on 23 interviews conducted with actuarial consultants and their clients and consulting agencies’ publically available documents. Taking framing theory and the sociological literature on risk as conceptual starting points, we find that consultants engage in specific framing strategies to persuade clients by rhetorically weaving a series of financial risk objects, financial de-risking strategies, and calls for action. We also find that current and prospective clients sometimes contest consultants’ prescriptions, despite the pervasiveness of risk management as the ultima ratio of organizational governance. This contestation occurs, ironically, because adopting de-risking solutions in one area is perceived by some clients as triggering new risks in areas unforeseen by consultants. This research increases our knowledge of how new risk objects and de-risking solutions come into existence and why some risk management practices fail to be diffused within organizations despite the staggering success of the risk management rationality. We explain the latter through the concepts of frame diffraction and overload

Estimating Value Creation from Revealed Preferences: Application to Value-Based Strategies

We develop and apply a new set of empirical tools consistent with the tenets of value-based business strategies, leveraging the principle that “no good deal comes undone” and the methods of revealed preferences to empirically estimate drivers of value creation. We demonstrate how to use these tools in an analysis of value creation in buyer–supplier relationships in the UK corporate legal market. We show how the method can uncover evidence of subtle mechanisms that traditional methods cannot easily distinguish from each other. Furthermore, we show how these estimates can be used as parameters of biform games for out-of-sample analyses of strategic decisions. With readily available data on relationships between firms, this approach can be applied to many other contexts of interest to strategy researchers
