Systemic risk,macroprudential policy frameworks,monitoring financial systems and the evolution of capital adequacy

This paper analyses various issues that need to be tackled when promoting financial stability, reviewing the progress made in certain key areas and the remaining challenges. It explores the measurement of systemic risk and of individual institutions’ contribution to it. It discusses aspects of macroprudential frameworks, including how the countercyclical capital buffer envisaged in Basel III takes into account the properties of the financial cycle and the strengths and weaknesses of macro-stress tests. It analyses some of the challenges of how best to monitor financial systems and the broader economy in order to detect signs of vulnerability that might lead to future bouts of financial instability and of how to set prudential policy accordingly. And it discusses the evolution of capital adequacy standards and the new emphasis on liquidity standards in international regulation.     

Trade credit in Europe: Financial constraint and substitution effect in crisis times

This paper aims to prove whether financial rationing condition leads European enterprises to increase trade debt during the period 2008–2016 and whether companies offering deferred payments to customers obtain trade debt from suppliers. The work contributes to the existing literature by finding new empirical evidence on the substitution and matching hypotheses in times of crises, measuring the specific rationing conditions for businesses and distinguishing large, medium, small and micro-sized companies. The results revealed that, in times of crisis, medium, small and micro firms, highly likely to be constrained, employ trade credit more extensively, as those granting deferred payment terms.     

Executive compensation and the performance of the firm

A sample of large industrial corporations is examined to determine whether there is a relationship between the levels of compensation received by the senior executives of those firms and the firms' economic performances. We find consistent evidence of such a relationship, with differences across firms in the total compensation of their three highest-paid officers being positively related to differences in both the common stock returns and operating profitability of the firms. The implication is that compensation packages are designed to reduce agency costs.     

Measuring and Optimizing Portfolio Credit Risk: A Copula‐based Approach*

In this work, we present a methodology for measuring and optimizing the credit risk of a loan portfolio taking into account the non‐normality of the credit loss distribution. In particular, we aim at modelling accurately joint default events for credit assets. In order to achieve this goal, we build the loss distribution of the loan portfolio by Monte Carlo simulation. The times until default of each obligor in portfolio are simulated following a copula‐based approach. In particular, we study four different types of dependence structure for the credit assets in portfolio: the Gaussian copula, the Student's t‐copula, the grouped t‐copula and the Clayton n‐copula (or Cook–Johnson copula). Our aim is to assess the impact of each type of copula on the value of different portfolio risk measures, such as expected loss, maximum loss, credit value at risk and expected shortfall. In addition, we want to verify whether and how the optimal portfolio composition may change utilizing various types of copula for describing the default dependence structure. In order to optimize portfolio credit risk, we minimize the conditional value at risk, a risk measure both relevant and tractable, by solving a simple linear programming problem subject to the traditional constraints of balance, portfolio expected return and trading. The outcomes, in terms of optimal portfolio compositions, obtained assuming different default dependence structures are compared with each other. The solution of the risk minimization problem may suggest us how to restructure the inefficient loan portfolios in order to obtain their best risk/return profile. In the absence of a developed secondary market for loans, we may follow the investment strategies indicated by the solution vector by utilizing credit default swaps.     

Currency unions and trade: The special case of EMU

In this paper, the impact of the adoption of the euro on the commercial transactions of EMU countries is investigated. It seeks to disentangle the effects of eliminating exchange rate volatility — and those of other policy factors that promote integration — from the influence of the emergence of the European currency union. Since EMU is a relatively new phenomenon, a panel estimation of the gravity equation in a dynamic framework is used in order to capture effects like trade persistence. The main finding is that the adoption of the euro has had a positive but not an exorbitant impact on bilateral trade between European countries (ranging between 9 and 10 per cent). The impact is much lower than that shown in the recent literature on a larger and heterogeneous set of countries. One reason for this divergence seems to be that the euro was adopted after decades of integration policies had already worked through in Europe. JEL no. F4, F15, C230     

Socialism and Intrafirm Asset Allocation

We rely on a survey of Swiss firms to document deviation from first‐best for reasons of internal ‘fairness’ when allocating resources. This ‘socialist’ practice is more widespread in smaller than in larger firms. It ignores the reputation and past performance of the managers who apply for funding, but takes into account their hierarchical position and their past use of resources. Socialism is only partially explained by concerns about empire building and managerial optimism, and it is not meant to benefit shareholders.     

Credit Counseling and Mortgage Termination by Low-Income Households

Published research on credit counseling and mortgage termination is surprisingly scarce, despite substantial growth in this industry. While the purpose of counseling is to assist low-income borrowers to improve their handling of debt and thereby reduce default, counseling may also improve the borrowers understanding of their financial position and thus induce optimal mortgage termination. Using a competing-risks framework, we study the effects on default and prepayment of a counseling program implemented in several Midwest states. We find weak evidence of that the default hazard was lower for graduates of the counseling program, but that their default behavior was more optimal. The prepayment hazard was higher for counseled borrowers, but their prepayment behavior was not more optimal. Overall, counseling seems to affect the lenders profits, but the net effect should be evaluated both in terms of prepayment and default.     

Beyond the labour income tax wedge: the unemployment-reducing effect of tax progressivity

In this paper, we argue that, for a given overall level of labour income taxation, a more progressive tax schedule increases employment. From a theoretical point of view, higher progressivity increases overall employment through a wage moderating effect and also because employment of low-paid workers is more elastic to wages. We test these theoretical predictions on a panel of 21 OECD countries over 1998–2008. Controlling for the burden of taxation at the average wage, our estimates suggest that a more progressive tax schedule reduces the unemployment rate and increases the employment rate. These findings are confirmed when we account for the potential endogeneity of both average taxation and progressivity. Overall, our results suggest that policy-makers should not only focus on the detrimental effects of tax progressivity on in-work effort, but also consider the employment-enhancing effects.     

Board Overlap, Seat Accumulation and Share Prices

We examine the board overlap among firms listed in Switzerland. Collusion, managerial entrenchment, and financial participation cannot explain it. The overlap appears to be induced by banks and by the accumulation of seats by the most popular directors. We also document that seat accumulation is negatively related to firm value, possibly because of the conflicts of interest that multiple directorships induce and the time constraints directors face. Contrary to popular beliefs, however, the directors of traded firms do not generally hold more than one mandate in other traded firms. They do hold multiple seats in non-traded firms.     

Stepwise Approach to the Long‐Term Management of Radioactive Waste1

Stepwise decision making has long been utilised as a tool for handling the technical complexity of radioactive waste management (RWM). Recently, it is being recognised as a useful means to address social complexities. This paper reviews—through a number of examples—the current developments regarding the stepwise approach to managing long‐lived wastes from a societal point of view with the aim of pinpointing where it stands, highlighting its social dimensions, and identifying guiding principles and issues in implementation. It is observed that there is convergence between the approach taken by the practitioners of RWM and the indications received from social research, and that general guiding principles can be distilled from the analysis of RWM case histories. The paper concludes that a stepwise approach to decision‐making indeed constitutes an effective tool, and that competing requirements of social sustainability and efficiency, openness and analytical rigour will need to be balanced. A long‐term process of decision‐making incorporating the views of national and local stakeholders will very likely be a difficult process to implement. The concrete arrangements for sketching out and agreeing on decision phases, for selecting and involving stakeholders in a participatory process, and for adapting institutions to meet long‐term requirements, will require careful reflection and tuning in each national context.
