Ex-Day Price Behaviour, Market Microstructure and Settlement Costs

It is well documented that share prices on ex-dividend days drop by less than the value of the dividends paid. However, the explanations offered to date remain inconclusive. This study examines the behaviour of share prices on ex-dividend days using data from the UK after the introduction of the 1988 Income and Corporation Taxes Act. Following [10] we sub-divide the data conditional on the size of the dividend paid. We find that for the large dividend sub-sample, when the impact of market micro-structure is taken into account, the ex-dividend price drop is not significantly different to the value of the dividend paid.     

Competition, interlisting and market structure in options trading

This paper applies a game theory approach to examine the effects of a market structure change in options trading from a monopoly to a Cournot-type oligopoly that occurred in two successive periods on the Montreal exchange. We analyze the intra-day behaviour of option bid-ask spreads and find that cross-listing has a differential impact on spreads, affecting quoted but not effective spreads under oligopoly. We also find that the impact of the change in structure on effective spreads comes mostly from an increase in limit orders and is consistent with a switch from Cournot to Bertrand-type strategic behaviour for such orders. We conclude that market structure effects within an options exchange are enough to realize most of the benefits of inter-market competition even in the context of market thinness.     

Regulation and competition in the European mobile communications industry: An examination of the implementation of mobile number portability

Over the past two decades, the mobile communications industry has seen a considerable drop in the consumer switching charges made by service providers in order to promote effective competition and ensure a level playing field for new market entrants. Mobile Number Portability (MNP) is an important regulatory measure taken to reduce switching costs, and it is believed to play an important role in fostering competition in the mobile market. MNP implementation has varied significantly across European Union countries, particularly with respect to porting time and customer fees, both of which are important factors when deciding whether to switch to another provider. The research examines the effects of MNP implementation on competition in the European mobile communications industry. The study findings indicate that subscriber churn rates are negatively affected by both the level of charges levied on subscribers wishing to maintain their current number (porting) when switching mobile providers and the length of time required to switch. The implications of the effectiveness of MNP regulation for competition in the mobile communications industry are discussed.     

Catastrophe futures and reinsurance contracts: An incomplete markets approach

We present a theoretical methodology for the pricing of catastrophe (CAT) derivatives with event‐dependent and non‐convex payoffs given the price of a CAT indexed futures contract. We do not assume a fully diversifiable CAT event risk, nor do we assume knowledge of the martingale probability measure beyond the futures price. We derive tight bounds on the contract value and present trading strategies exploiting the mispricing whenever the bounds are violated. We estimate the bounds of the reinsurance contract with data from hurricane landings in Florida. Our method is also applicable when there is no futures market but the price of a CAT‐indexed bond is available.     

International law as a negotiation tool in Banking Union; the case of the Single Resolution Fund

EU’s response to the recent Euro-crisis has involved a mixture of EU and international law, with the latter being linked to all the arrangements that may have fiscal implications for national Member States. The SRF embodies all the controversial characteristics of Banking Union. This article illustrates the legal implications that this political choice creates, and how the interrelation between the SRM, the SRF and the ESM, allows leading economies, including Germany, to control the resolution framework both before and after crisis. This raises questions as to the direction that European Integration is taking and its highly nationalised character.

The Timeliness of Income Recognition by European Companies: An Analysis of Institutional and Market Complexity

This study examines international differences in the asymmetric timeliness of accounting earnings by modelling international exposure to different jurisdictions as a firm-specific effect, using an index of regulatory complexity that relates to conditions in each of the capital markets in which the firm's equity is listed. The companies investigated are those with shares cross-listed on European stock exchanges, some of which are also listed in New York. Variation across jurisdictions and markets with respect to earnings timeliness and conservatism can be explained in part as an interaction of market effects and regulatory effects, with some evidence of opposition between the two, and the sensitivity of earnings to stock price changes shows a common, converging trend towards greater accounting conservatism in Europe.     

Productivity change and its determinants among leading mobile operators in Europe

The European mobile telecommunications industry has seen increased competition and market saturation in recent years, so improving productivity will become crucially important for mobile operators in the near future. This study adopts a bootstrap Malmquist index approach to estimate productivity change among a sample of 23 of Europe's leading mobile operators over the 2008 to 2009 period. Using a second-stage regression, this article also analyses the determinants of productivity changes in terms of regulation, competition and ownership structure. The results show that mobile companies operating in countries that have recently joined the EU have a positive association with productivity change, in contrast to their counterparts in South-East Europe. Concerning market competition, the leading mobile operators that experience higher productivity changes operate in more concentrated markets. The results also indicate that international mobile operators perform better in terms of productivity change than their national equivalents. Finally, some of the implications of the findings for mobile operators’ management and policymakers are provided.
