Peer Group Formation in an Adverse Selection Model

This paper develops an adverse selection model where peer group systems are shown to trigger lower interest rates and remove credit rationing in the case where borrowers are uninformed about their potential partners and ex post state verification (or auditing) by banks is costly. Peer group formation reduces interest rates due to a 'collateral effect', namely, cross subsidisation amongst borrowers acts as collateral behind a loan. By uncovering such a collateral effect, this paper shows that peer group systems can be viewed as an effective risk pooling mechanism, and thus enhance efficiency, not just in the full information set up.     

The Presence of Multinational Banks and the Supply and Quality of Credit in Emerging Economies

Barriers to entry for multinational banks (MNBs) have been reduced in many countries. This paper studies the effect of the presence of MNBs on the supply and quality of credit in emerging economies. This study uses data from the Bank for International Settlements and the International Monetary Fund. The results indicate that the credit supply declines in response to increased competition from MNBs. However, the adverse effect of MNBs on the credit supply is less pronounced when the presence of MNBs is larger. The paper also provides some tentative results on the effect of MNBs on the quality of loans. The results suggest that banks shift their portfolios away from loans as a result of increased international financial competition, thereby reducing default risk, which is also reflected in a negative relationship between MNB presence and the chance of a banking crisis occurring.     

Capital Mobility, Consumption Substitutability and the Effects of Monetary Policy in Open Economies

Abstract. I use a dynamic general equilibrium two‐country optimizing model to analyze the implications of international capital mobility for the short‐run effects of monetary policy in an open economy. The model implies that the substitutability of goods produced in different countries plays a central role for the impact of changes in the degree of international capital mobility on the effects of monetary policy. Paralleling the results of the traditional Mundell–Fleming model, a higher degree of international capital mobility magnifies the short‐run output effects of monetary policy only if the Marshall–Lerner condition, which is linked to the cross‐country substitutability of goods, holds.     

Bewertung und Steuerung von Gasspeichern bzw. Gasspeicherscheiben

In this paper you find a brief introduction to the German gas market as well as a draft of the resulting storage requirements in Germany. In the following different storage usages are looked into from an economical perspective. Additionally the presented evaluating methods in this paper are specified. This paper then introduces stochastic optimization methods which give the possibility to assess the storage against the spot price as well as against to the whole forward curve. For this models to evaluate the market price are illustrated and calibrated on the basis of empirical data.After this a sample storage slice is rated with the Least-Square-Monte-Carlo method based on a stochastic multi factor spot price model. Then the hedging evaluation against the whole forward curve is presented. Concluding you find a comparison of the two methods.     

Exploring the conditions under which salesperson work satisfaction can lead to customer satisfaction

A number of recent research studies have demonstrated the presence of a positive link between customer‐contact employees' work satisfaction and customer satisfaction. However, existing studies have largely neglected describing conditions under which the link between these two constructs is stronger or weaker. The authors of this study argue that certain customer characteristics (such as customer trust, customer price consciousness, and the importance of product/service to the customer) and salesperson characteristics (such as empathy, expertise, and reliability) moderate the relationship between salespeople's work satisfaction and customer satisfaction. Balance theory is used to justify the hypotheses of the study. Tests of the hypotheses are based on a dyadic data set collected across manufacturing and services industries in a business‐to‐business context. Results reveal that the link between work satisfaction and customer satisfaction is systematically moderated by the salesperson and customer characteristics under consideration. © 2005 Wiley Periodicals, Inc.     

Return Migration: Theory and Empirical Evidence from the UK

In this article, we discuss forms of migration that are non‐permanent. We focus on temporary migrations where the decision to return is taken by the immigrant. These migrations are likely to be frequent, and we provide some evidence for the UK. We then develop a simple model that rationalizes the decision of a migrant to return to his/her home country, despite a persistently higher wage in the host country. We consider three motives for a temporary migration: (i) differences in relative prices between host and home country, (ii) complementarities between consumption and the location where consumption takes place, and (iii) the possibility of accumulating human capital abroad, which enhances the immigrant's earnings potential back home. For the last return motive, we discuss extensions that allow for immigrant heterogeneity, and develop implications for selective in‐ and out‐migration.     

Unpacking tourism SMMEs in South Africa: structure,support needs and policy response

Small enterprise (SMME) support policy in post-apartheid South Africa has traditionally involved support initiatives in the form of ‘generic’ packages that overlook the specificities of particular sectors. In this article the specific issues concerning SMME development in tourism are investigated. Against a backcloth of a review of international scholarship on tourism small firms, the article presents findings from recent empirical investigations into the progress and problems of tourism SMME development in South Africa. Within the international scholarship and policy debates on tourism, it is argued that the South African experience is particularly distinctive in two respects: (1) the support of particular groups of tourism SMMEs linked to objectives of transformation and (2) the introduction of dedicated tourism-specific support programmes for SMME development.     

How broker ability affects institutional trading costs

The present paper shows that broker research and trade execution ability has a significant impact on the cost of institutional trading. The results reveal that there is significant variation in the ability of brokers to control execution costs. Trades executed by brokers with stronger research ability exhibit a higher permanent price impact, whereas those executed by brokers with better execution ability exhibit a lower temporary price impact. Brokers are also found to specialize on an industry level that gives rise to variation in ability within a brokerage house.
