Disentangling and quantifying market participant volatility contributions

Thanks to the access to labeled orders on the CAC 40 index future provided by Euronext, we are able to quantify market participants contributions to the volatility in the diffusive limit. To achieve this result, we leverage the branching properties of Hawkes point processes. We find that fast intermediaries (e.g. market maker type agents) have a smaller footprint on the volatility than slower, directional agents. The branching structure of Hawkes processes allows us to examine also the degree of endogeneity of each agent behavior, and we find that high-frequency traders are more endogenously driven than other types of agents.     

The fundamental theorem of asset pricing under transaction costs

This paper proves the fundamental theorem of asset pricing with transaction costs, when bid and ask prices follow locally bounded càdlàg (right-continuous, left-limited) processes. The robust no free lunch with vanishing risk condition (RNFLVR) for simple strategies is equivalent to the existence of a strictly consistent price system (SCPS). This result relies on a new notion of admissibility, which reflects future liquidation opportunities. The RNFLVR condition implies that admissible strategies are predictable processes of finite variation. The Appendix develops an extension of the familiar Stieltjes integral for càdlàg integrands and finite-variation integrators, which is central to modelling transaction costs with discontinuous prices.     

On the Segment Identification Issue

Disclosure of financial data disaggregated by business and/or geographic segment is currently being considered by the Accounting Standards Committee. This paper reports the views of a group of preparers and users of segment reports on the segmental reporting issue. Identifying reportable segments is of primary importance if the disaggregated financial data are to have any meaning or value. Yet, the imposition of a rigid and arbitrary set of rules suggesting a single form of presentation is unlikely to gain universal approval. Based on the criteria of the preparers and users interviewed alternative forms of presentation are proposed.     

Performance and Merton-type default risk of listed banks in the EU: A panel VAR approach

This paper provides empirical evidence that sheds new light into the dynamic interactions between risk and efficiency, a highly debated issue. First, we estimate three alternative measures of bank performance, by employing a directional distance function framework, along with a cost frontier and a profit function. As a second step, we calculate a Merton-type bank default risk. Then, we employ a panel VAR analysis, which allows the examination of the underlying relationships between efficiency and risk without applying any a priori restrictions. Most evidence shows that the effect of a one standard deviation shock of the distance to default on inefficiency is negative and substantial. There is some evidence of a reverse causation. As part of a sensitivity analysis, we extent our study to investigate the relationship between efficiency and default risk for banks with different types of ownership structures and across financial systems with different levels of development.     

Sociality and money1

This is a translation of ‘Socialité et argent’, a text by Emmanuel Levinas originally published in 1987. Levinas describes the emergence of money out of interhuman relations of exchange and the social relations – sociality – that result. While elsewhere he has presented sociality as ‘nonindifference to alterity’ it appears here as ‘proximity of the stranger’ and points to the tension between an economic system based on money and the basic human disposition to respond to the face of the other person. Money both encodes and effaces sociality, both designates and disguises social relations. It arises from the way that needs and interests are manifested in exchange relations, in what he calls the ‘interestedness’ of economic life. But interests are always already cut through by the fact that being is always ‘being with others’. Being is always ‘interbeing’. Interestedness is always confronted by disinterestedness, that is, by a sociality marked by the ‘goodness of giving’, attachment to and concern for the poverty of the other person. Levinas concludes with a discussion of sociality and justice, posing questions about the tension between the demand to respond to an Other immediately before me and at the same time to respond to the demands of an other Other (the third person) who also invites a response.     

Cross-border restaurant price and exchange rate interactions

Purchasing power parity suggests that international price ratios for identical goods should approximate nominal exchange rates for the currencies in which the prices are denominated. Deviations of the price ratios from exchange rates can occur for a number of reasons and mixed evidence has been recorded for how long those deviations last. Empirical evidence for international restaurant prices in El Paso, Texas and Ciudad Juarez, Mexico confirms that menu item price ratios are strongly correlated with the peso/dollar exchange rate. An earlier exploratory study of eight individual products also indicated that half-life deviations in this market are very short. This study utilizes additional data from a larger and more extensive sample to examine if the prior results are confirmed.     

Value Creation in Inter-Organizational Collaboration: An Empirical Study

Over the last decade, businesses, policymakers, and researchers alike have advocated the need for (and potential of) value creation through inter-organizational collaboration. Researchers have widely argued that organizations that are engaged in collaborative processes create value. Because researchers have tended to focus on the identification of organizational motivations and on key success factors for collaboration, however, both the nature and processes of value creation in inter-organizational collaboration have yet to be examined. A recent theory by Austin and Seitanidi (Nonprofit Volunt Sect Q 41(5):726–758, 2012a; Nonprofit Volunt Sect Q 41(6):929–968, 2012b) has proposed an analytical framework for analyzing value creation in inter-organizational collaboration, based on four types of value. The purpose of this current study is to empirically test this framework, and to provide key pointers for analyzing the nature of value, particularly in relation to learning. Our detailed empirical research is based on a 6-year retrospective case study of an inter-organizational partnership within an international development project for local economic development in Guatemala. The study’s contributions are twofold. First, it provides evidence of the critical path of the creation of diverse types of values in a collaborative process; second, it links the different types of value creation with the types of learning that occur in an inter-organizational process.     

(Not So) Easy Come, (Still) Easy Go? Footloose Multinationals Revisited

The central question of this paper is to test whether multinational firms (MNFs) are more likely to exit the local market than domestic firms. Using firm‐level data for Belgium, we estimate a random effects probit model taking into account the endogeneity of firm size, total factor productivity (TFP) and sunk costs in firm exit. Our results highlight two features of the ‘footloose’ nature of MNFs. First, controlling for firm and sector characteristics, the exit probability of MNFs is larger than that of domestic firms. Second, MNFs have a lower sensitivity to TFP and size than do domestic firms. This means that an improvement in economic performance on the local market will not prevent a multinational from closing its local plant as much as it would for a domestic firm.     

The Performance of Trading Firms in the Services Sectors – Comparable Evidence from Four EU Countries

We examine trade complexity and the implications of adding additional dimensions of trade for firm performance among services producers. We use unique firm‐level data to compare these patterns across four EU countries. Overall, services firms are relatively less engaged in trade than manufacturing firms; they mostly trade goods and are more likely to import than to export. Trade in services is quite rare; services are more likely to be traded by firms already trading goods. Trading firms in the services sectors are significantly larger, more productive and pay higher wages than non‐traders. Two‐way traders outperform one‐way traders. Changes in trading status by either adding another dimension of trade (imports, exports) or another type of product (goods, services) are infrequent and are associated with significant preswitching premia. In contrast, learning effects from switching trading status are uncommon. This points to significant fixed cost of being engaged in trade and confirms some previous findings that trading services firms have similar traits as their manufacturing counterparts. Apart from greater trade participation in smaller countries, we do not observe systematic differences in terms of trade or switching premia between the four countries that might be attributable to differences in country characteristics.     

Service sabotage: The dark side of service dynamics

While many aspects of services research assume that employees are largely compliant to management prescribed service standards, a number of recent studies have highlighted the deliberate sabotage by service workers as a key issue. We contend that service sabotage is important not simply because of the pervasiveness of such behaviors, but also because of the impact that such acts can have on firm growth and profitability. Consequently, we seek to achieve three inter-linked objectives in this article. First, we highlight how service saboteurs harm customers’ service experiences and negatively affect the performance of the firm. Second, in order to assist managers in recognizing these behaviors, we identify the most common types of service saboteurs and forms of sabotage. Specifically, we classify and describe four main types of service saboteurs: Thrill Seekers, Apathetics, Customer Revengers, and Money Grabbers. Finally, and most importantly, we provide a series of suggestions regarding how managers might effectively address service sabotage in their firms. These include gathering information and exploiting existing data to establish the extent and nature of sabotage, recruiting the right quality of service staff, training and rewarding employees, enriching and empowering employees, developing a service culture, and initiating better monitoring systems and procedures.
