Block trades in options markets

Block trading, which was sparse before the reduction of the minimum permissible block size threshold in October 2012, currently accounts for about 30% of the trading volume in WTI crude oil options. Block orders share similar characteristics to those routed at the pit, but they have lower information content and face higher execution costs, due to high search costs. However, our results show that such block orders would have been costlier to execute at the pit, which suggests that some pit order flow may have migrated to the upstairs market, contributing to the eventual demise of energy options pits.     

Supply chain immune system: concept,framework, and applications

Behind every product and service is a supply chain. These supply chains are extremely complex and vulnerable to multifarious risks that threaten their performance and stability, ranging from simple machine or truck breakdowns to catastrophic natural disasters. This paper presents a novel framework for supply chain risk management based on the analogy of the biological immune system, which has multiple layers of increasing sophistication to neutralise a variety of risks. The various layers include: physical barriers, innate response, and adaptive response. The working of the framework is explained with an illustrative semiconductor supply chain. Applications of this framework include short-term disruption response and long-term immunisation, providing planner and manager level insights respectively.     

Excessive Dollar Debt: Financial Development and Underinsurance

We propose that the limited financial development of emerging markets is a significant factor behind the large share of dollar-denominated external debt present in these markets. We show that when financial constraints affect borrowing and lending between domestic agents, agents undervalue insuring against an exchange rate depreciation. Since more of this insurance is present when external debt is denominated in domestic currency rather than in dollars, this result implies that domestic agents choose excessive dollar debt. We also show that limited financial development reduces the incentives for foreign lenders to enter emerging markets. The retarded entry reinforces the underinsurance problem.     

Evidence on the Joint Determination of Audit and Non-Audit Fees

In this study we investigate whether the characteristics of clients, auditors, and the auditor‐client relationship simultaneously determine audit and non‐audit fees. As done in prior studies, we maintain that fees proxy for the level of service provided and follow the physical flow of knowledge. Estimating single‐equation models of audit and non‐audit fee models, we confirm prior findings of an association between audit and non‐audit fees. Studies conclude that such evidence is consistent with knowledge spillovers between the two services. However, we document empirically that audit and non‐audit fees are simultaneously determined. Because the data indicate audit and non‐audit fees are jointly determined, we then investigate whether previously documented associations between audit and non‐audit fees are the result of biased estimation induced by using endogenous variables in single‐equation models. In contrast to results from single‐equation estimations, we find no association between audit and non‐audit fees using a simultaneous specification of the fee system, suggesting that single‐equation estimations suffer from simultaneous‐equations bias. In sum, the findings are not consistent with the existence of economies of scope from the joint performance of audit and non‐audit services after controlling for the joint behavior of audit and non‐audit fees. Given the ongoing debate over the level of allowed non‐audit services by auditors, the argument for the joint provision of audit and non‐audit services is less justified than if joint‐supply benefits had been documented.     

Residual Claims in Co‐operatives: Design Issues

This paper examines issues in the design of a co‐operative member's contractual relationship with the other agents (including the remaining members) using organizational economics. The paper assumes that the central defining characteristic of a co‐op is the residual claim specification. Agency theory identifies certain inherent problems of the co‐op form, the horizon problem, common property problem, and non‐transferability. Non‐transferability both reduces the incentive to monitor and imposes limits on portfolio diversification. This paper argues that features such as claim incompleteness and non‐transferability are not inherent to the co‐op but may be transaction‐cost economizing. The paper also argues that the pre‐emptive payoff feature by which the residual claimants (the co‐op members) also become fixed payoff agents can affect the risk of other agents, and is an important determinant of co‐op risk. A co‐op may have more than one potential residual claim base. Five generic design choices are available for handling possible multiple claim bases: battleground, pre‐specified allocation, limited return, alignment, and fixed payoff. The paper uses the design of residual claims in sugar co‐ops to show how a co‐op can partly overcome some of the problems identified by agency theory. This illustration ties together the issues of claim incompleteness and non‐transferability, pre‐emptive payoff, and multiple claim bases.     

The Quality of Life in England and Wales*

Local amenities play an important role in determining where we choose to live and our overall quality of life (QOL). In many cases, however, amenities do not have prices and will therefore be underprovided by the market. In this paper, we use individual and county level data for England and Wales to estimate implicit amenity prices and to calculate an index of QOL for each county. Among our findings is a large negative price on air pollution. The range in QOL across counties is estimated to be in excess of 2,000 pounds per year.
