Are there any cost and profit efficiency gains in financial conglomeration? Evidence from the accession countries

Diversified banks should benefit from an efficient allocation of resources, debt coinsurance and scope economies. At the same time, critics of diversification question these advantages pointing to agency problems such as managerial entrenchment and empire building that could also lead to diversification but for the ‘wrong’ reasons. This paper sheds further light on the issue of bank diversification by taking a direct look into how efficiently financial conglomerates operate and by measuring to what extent size and other bank- and market-specific factors matter in evaluating the relationship between diversification and efficiency. We focus on banks operating in the accession countries over the period 2001–2007 and estimate their cost and alternative profit efficiencies using a data envelopment analysis estimator. The results indicate that banks suffer from relatively high cost and profit inefficiencies and that there are noticeable differences in the efficiency levels across countries. Concerning banks’ degree of diversification, we find strong evidence to suggest that more diversified institutions are more likely to be cost- and profit-efficient and that size is a key factor in explaining best practice, particularly on the profit side.     

Looking for a safe haven after fancy thrills: a psychometric analysis of risk perception in alpine tourist destinations

Visitors’ risk perceptions have been found to influence the on‐site behaviour of tourists and their intention to return to a destination or to recommend it to others. The present study analyses the perception of tourism risks in the Tyrol, Austria. Building on the psychometric paradigm, participants (N = 207) assessed 15 vacation risks on nine risk characteristics that are derived from psychometric research and completed with characteristics relevant in a tourism context. Findings suggest that additionally to managing the most likely risks, alpine destinations should be prepared to cope with worst case scenarios such as ‘potable water poisoning’, ‘food poisoning’, ‘breaking of an embankment dam’, ‘rock fall on a village’, ‘cable car accident’ and ‘terrorist attack’. Considering these rather low‐probability risks is of decisive importance since such risks are especially prone to evoke public outrage if they – against all expectations – result in damaging events.     

Analysing the determinants of bank efficiency: the case of Italian banks

Since PHILLIPS (1958) wrote his landmark article on the relationship between money wage rates and unemployment, much work has been conducted concerning ‘Phillips’ curves'. While some writers, such as LIPSEY (1960), SAMUELSON and SOLOW (1960) and HANSEN (1970), remained relatively close to Phillips' original model, other strayed from it. BRECHLING (1968), DICKS-MIREAUX and DOW (1959), ECKSTEIN (1968), ECKSTEIN and WILSON (1962), HAMERMESH (1970), KUH (1967), PERRY (1966), PHELPS (1968), and TAYLOR (1970) are a few researchers who felt Phillips' formulation did not adequately explain changes in money wage rates. Their approaches ranged from formulating entirely new models to merely adding other explanatory variables to Phillips' model.

The present study estimates a Phillips' curve for the United Kingdom within the framework of Phillips' basic hypothesis. He grouped all observations according to unemployment levels, averaged the wage changes for each group, and fitted a curve by trial and error to the compact body of data. The current approach fits a curve to all data points using a direct estimation procedure. Only two basic variables are used; money wage rates and unemployment.

REES and HAMILTON (1967) pointed out that the estimated relation between wage changes and unemployment is highly sensitive to the form of the variables and the regression employed. One can obtain widely scattered results by either changing the type of numerical analysis on existing data or by changing the defined variables. It would not be surprising if the results of the present analysis differ from previous works. Not only are some of the data sources different from those previously employed but the numerical analysis is entirely new to Phillips' curve theory. Spline theory is used to fit the Phillips' curve.     

Information and size of coalitions

We consider a set of asymmetrically informed agents, where the information of each trader is susceptible of being altered when she becomes a member of a coalition. For this, we consider a general rule that depending on the coalition, a signal (or an information partition) is assigned to each member of the coalition. We set examples showing that Grodal’s (Econometrica 40:581–583, 1972), Schmeidler’s (Econometrica 40:579–580, 1972) and Vind’s (Econometrica 40:585–586, 1972) core characterizations of a continuum economy may fail in this general informational setting. However, under mild assumptions on the rule, we extend Schmeidler’s and Vind’s results to economies that allocate information to agents in each coalition according to the rule. We then focus on information mechanisms based on the size of coalitions and provide a general characterization result for the corresponding cores. Moreover, we pay close attention to the rule that assigns the shared information to each member of specific coalitions. We prove that the resulting cores are exactly the same independently of whether arbitrarily small or large coalitions share information.     

Makroprudenzielle Politik

The aim of macroprudential policy is to oversee financial stability and to safeguard the stability of the financial system. Systemic risk arises if distressed financial institutions put the stability of the entire financial system at risk, thus impairing its functioning and the provisioning of services to the real economy, with negative implications for economic growth. Macroprudential policy aims at increasing the overall resilience of the financial system by monitoring the allocation of risk in the financial system and by preventing the build-up of excessive risks. In the aftermath of the crisis, new institutions were established and macroprudential instruments were created. Responsibility for macroprudential policy is located mostly at the national level. Due to its international dimension it is embedded into a network of international institutions     

Openness and growth: The long shadow of the Berlin Wall

The question whether international openness causes higher domestic growth has been subject to intense discussions in the empirical growth literature. This paper addresses the issue in the context of the fall of the Berlin Wall in 1989. We analyze whether the slow convergence in per capita incomes between East and West Germany and the lower international openness of East Germany are linked. We address the endogeneity of openness by adapting the methodology proposed by Frankel and Romer (1999) to a panel framework. We instrument openness with time-invariant exogenous geographic variables and time-varying exogenous policy variables. We also distinguish the impact of different channels of integration. Our paper has three main findings. First, geographic variables have a significant impact on regional openness. Second, controlling for geography, East German states are less integrated into international markets along all dimensions of integration considered. Third, the degree of openness for trade has a positive impact on regional income per capita.     

Testing the relationship between competition and efficiency in banking: A panel data analysis

The relationship between competition and efficiency in the banking sectors of five EU countries is investigated using Granger-type causality test estimations. We find positive causation between market power and efficiency, whereas the causality running from efficiency to competition is weak.     

Existence of Edgeworth equilibria for economies with asymmetric information

We analyze a general equilibrium model with asymmetrically informed agents. A basic and well-known consequence of asymmetric information is the failure of equal treatment property. Despite of this, we show that in every replica economy a private core allocation, which treats agents of the same type equally, exists. This result is provided in the framework of two different models, with and without expectations, and it suffices to guarantee in both cases the existence of a private Edgeworth equilibrium.

Do discounted food products end up in the bin? An investigation into the link between deal‐prone shopping behaviour and quantities of household food waste

Household food waste is considered to be the largest share of food waste along the food supply chain. Given that its recoverability is also more challenging compared to food waste in other stages of the chain, most studies on household food waste adopt a pre‐emptive approach by aiming to identify and address consumer beliefs, attitudes and actions that are linked to food waste. In scientific literature, household food waste has often been studied in relation to the habit of purchasing discounted food products (DFP). However, findings have been contradictory. Specifically, while some authors found that deal‐prone consumers are usually of lower income and therefore display a wiser and more attentive attitude towards grocery shopping, other authors reported that the purchase of discounted products was usually linked to compulsive shopping, hence resulting in higher food waste quantities at home. Due to these discrepant findings, a definitive answer on the impact of DFP on household food waste does not currently exist in the literature. This paper analyses the correlation between the purchase of DFP and weekly household food waste quantities. To do so, we examine (a) the results of a food waste diary experiment carried out on a representative sample of 385 households in Italy in February 2017, and (b) the results of a 23‐items Computer Assisted Web Interview survey administered to the same householders, in which shopping habits were investigated. Results revealed no evidence of either a positive or negative relationship between the purchase of DFP and household food waste quantities. Frequency of grocery shopping was the only variable found to have a significant impact on household food waste quantities.
