Risk arbitrage and hedging to acceptability under transaction costs

The classical discrete-time model of proportional transaction costs relies on the assumption that a feasible portfolio process has solvent increments at each step. We extend this setting in two directions, allowing convex transaction costs and assuming that increments of the portfolio process belong to the sum of a solvency set and a family of multivariate acceptable positions, e.g. with respect to a dynamic risk measure. We describe the sets of superhedging prices, formulate several no (risk) arbitrage conditions and explore connections between them. In the special case when multivariate positions are converted into a single fixed asset, our framework turns into the no-good-deals setting. However, in general, the possibilities of assessing the risk with respect to any asset or a basket of assets lead to a decrease of superhedging prices and the no-arbitrage conditions become stronger. The mathematical techniques rely on results for unbounded and possibly non-closed random sets in Euclidean space.

     

Compound trend renewal process with discounted claims: a unified approach

We derive recursive formulas for the moments of compound trend renewal sums with discounted claims. An integral expression for the moment generating function of this risk process is then obtained, from which particular distribution functions are found. We extend the compound (deterministic) trend renewal process by assuming a stochastic trend, a stochastic force of net interest and a stochastic dependence between the inter-occurrence times and the severities of the claims. Finally, stochastic dominance ordering is also observed between the compound trend renewal process and an associated non-homogeneous Poisson process.     

Adjusting an institutional framework to a globalising world: the creation of new institutions in the EEC, 1957-1992

ABSTRACT

This article explores the development of all new EEC institutions between 1957 and 1992 within policy areas relevant to the possible development of a European single currency. It argues that if most institutions created pre-1992 were not crisis management institutions as would be the case post-2008, some important institutions were created in response to the perception of a structural international banking/political/economic crisis, particularly in the 1970s. This comparison in time underlines the continuity of reflections about the missing elements of a functioning single currency area, the obstacles to reform, and sheds light on the radical institutional changes that occurred post-2008.     

Selecting Board Members: The Impact of Common Knowledge on Gender Diversity – An Experimental Investigation

Using a corporate governance experiment, we explore the role of common knowledge of diversity on board members' selection. Our results show that common knowledge of diversity impacts significantly and negatively the proportion of women selected on boards and in a higher proportion in sectors perceived as ‘masculine’. We also bring evidence of an order effect that makes the selection of men on boards likelier for the first chosen members. This bias is stronger for male decision makers. This article provides implications and directions for future research for the understanding of decision making involved in the selection process for board members.

What is the impact of problem loans on Japanese bank productivity growth?

This paper examines for the first time the impact of problem loans on Japanese productivity growth. We exploit a new data set of Japanese problem loans classified into two categories: bankrupt and restructured loans. We opt for a novel and flexible productivity growth decomposition that allows to measure the direct impact of these problem loans on productivity growth. The results reveal that Japanese bank productivity growth was severely constrained by bankrupt and restructured loans early in 2000s, whilst some persistence of the negative impact of problem loans on productivity growth is observed in the late 2000s. Thereafter, there is only some partial recovery in the productivity growth from 2012 to 2015. Further, we also perform cluster analysis to examine convergence or divergence across regions and over time. We observe limited convergence, though Regional Banks seem to form clusters in some regions.     

The impact of 11/13 Paris terrorist attacks on stock prices: evidence from the international defence industry

This study explores the effect of the Paris terrorist attacks on the stock returns and the volatility for the most important companies in the global defence industry. To this end, it employs the General Autoregressive Conditional Heteroscedasticity methodology. The findings clearly indicate that this terrorist event has a positive impact on both the returns and the volatility of these stocks.     

Ill‐Defined versus Precise Pre‐Play Communication in the Traveler's Dilemma

This article reports results from an experiment comparing the effects of vague versus precise pre‐play communication in a highly competitive two‐player game with conflicting interests. In the classic Traveler's Dilemma, non‐binding precise messages about intent of play are pure cheap talk. We conjecture that a form of imprecise pre‐play communication whereby subjects can submit ill‐defined messages may help foster cooperation because of their vagueness. Comparing behavior both across modes of communication and to a baseline case without communication, we find that cooperation is highest when players can communicate using precise numerical messages. When communication with ill‐defined messages is allowed, then conditional on receiving a message, subjects act more cooperatively than when no message is received. However, overall, the ability to exchange ill‐defined messages does not substantially improve cooperation.
