Regulating collateral-requirements when markets are incomplete

In this paper we examine the effects of default and collateral on risk sharing. We assume that there is a large set of assets which all promise a risk less payoff but which distinguish themselves by their collateral requirements. In equilibrium agents default, the assets have different payoffs, and there are as many linearly independent assets available for trade as there are states of the world. We derive necessary and sufficient conditions for equilibria to be Pareto-efficient in the presence of uncertainty. We explore some examples for which the collateral equilibrium allocation is identical to the Arrow–Debreu allocation, either when agents have a high preference for the durable good, or when the endowment distribution of the durable good is relatively homogeneous. We examine a series of examples to understand which collateral-levels prevail in equilibrium and under which conditions there is scope for regulating margin-requirements, that is, restricting the sets of tradable assets through government intervention. In these examples equilibrium is always sub-optimal but regulation never leads to a Pareto-improvement. While the competitive equilibria are constrained efficient, there do exist regulations which make large groups of agents in the economy better off. These regulations typically restrict all trades to take place in the low-collateral loans and benefit the poor and the rich agents in the economy through their effects on the equilibrium interest rate and the equilibrium prices of the durable goods.     

Individual risk attitudes and the composition of financial portfolios: Evidence from German household portfolios

This paper explores the relationship between the self-declared risk aversion of private investors and their propensity to hold incomplete portfolios of financial assets. The analysis is based on household survey data from the German Socioeconomic Panel (SOEP) that provides a reliable measure of individual attitudes toward financial risk. Our findings suggest that more risk averse households tend to hold incomplete portfolios consisting mainly of a few risk-free assets. We also find that the propensity to acquire additional assets is highly dependent on whether liquidity and safety needs are met.     

Political patronage in Ukrainian banking1

This paper empirically investigates the link between political patronage and bank performance for Ukraine during 2003Q3–2005Q2. We find significant differences between politically affiliated and non‐affiliated banks. The data suggest that affiliated banks have significantly lower interest rate margins and increase their capitalization. Furthermore, we show that the level of activity of affiliated deputies in parliament has a positive (negative) impact on banks’ capitalization ratio (interest rate margin). Our findings imply, in line with the related literature, that political affiliation has important effects on banks’ behaviour.     

Bad bank(s) and the recapitalisation of the banking sector

With banking sectors worldwide still suffering from the effects of the financial crisis, public discussion of plans to place toxic assets in one or more bad banks has gained steam in recent weeks. The following paper presents a plan how governments can efficiently relieve ailing banks from toxic assets by transferring these assets into a publicly sponsored workout unit, a so-called bad bank. This plan effectively addresses three key challenges. It provides for the transparent removal of toxic assets and gives the banks a fresh start. At the same time, it offers the chance to keep the cost to taxpayers low. In addition, the risk of moral hazard is curtailed.     

How to communicate sustainable tourism products to customers: results from a choice experiment

This multiphase and empirical study explores the best communication style for reaching different international tourism markets and provides an understanding of how purchase decisions could be better influenced in travel brochures. A pre-test experiment evaluated the perceived emotionality and rationality of communication elements in a fictional travel brochure designed for a typical beach holiday but managed according to sustainability principles. In phase two, a choice experiment was conducted to test how Swiss, German, British and US travellers could be influenced by varying visual and textual communication elements in the fictional brochure (based on Mexico for US respondents and Menorca for all others). The choice experiment produced 3006 responses from an online survey in the four countries. Results confirm a general preference for emotionally laden communication styles for sustainable tourism products, while respondents were indifferent to the emotionality of standard product feature communications. Respondents did not show a preference for the inclusion of a graph explaining the product's sustainability attributes.     

On the Regulation of Social Norms

A model is developed to understand how norms can be influencedby "norm entrepreneurs," for example, lawmakers, governmentagencies, unions, etc. Two instruments of influencing the dynamicsof norm-following behavior are analyzed, namely transformingthe (monetary) incentives and changing the meaning or the reputationalvalue of following a norm. Both forms of norm regulation areincorporated into Akerlof's model of social custom (1980), andthe comparative static properties of norm destruction and normcreation for different types of norms are derived. In particular,it is shown how norms should be regulated when almost everybodyfollows them and when they take the form of bandwagon and snobnorms.     

Corporations as Political Actors – A Report on the First Swiss Master Class in Corporate Social Responsibility

This paper presents a report on the first Swiss Master Class in Corporate Social Responsibility, which was held between the 8th and 9th December 2006 at HEC Lausanne in Switzerland. The first section of the report introduces the topic of the master class – ?Corporations as Political Actors – Facing the Postnational Challenge’ – as well as the concept of the master class. The second section gives an overview of papers written by nine young scholars that were selected to present their research. The brief summary of each paper also includes a summary of comments from the masters, practitioners, and NGO representatives at the event. The third section brings in the perspectives of one master and one NGO representative on the discussed issues. The final section offers a brief wrap-up of the discussed topics and outlines ways to structure future conceptual and empirical research.     

The impact of the financial system’s structure on firms’ financial constraints

We estimate firms’ cash flow sensitivity of cash to empirically test how the financial system’s structure and level of development influence their financial constraints. For this purpose we merge Almeida et al.’s work, a path-breaking design for evaluating a firm’s financial constraints, with that of Levine, who paved the way for comparative analysis of financial systems around the world. We conjecture that a country’s financial system, both in terms of its structure and its level of development, should influence the cash flow sensitivity of cash of constrained firms but leave unconstrained firms unaffected. We test our hypothesis with a large international sample of 30,000 firm-years from 1989 to 2006. Our findings reveal that both the structure of the financial system and its level of development matter. Bank-based financial systems provide constrained firms with easier access to external financing.
