Do We Need New Modelling Approaches in Macroeconomics?

Financial Cycles and the Real Economy: Lessons for CESEE Countries,
2014
Abstract
The economic and financial crisis that emerged in 2008 also initiated an intense discussion on macroeconomic research and the role of economists in society. The debate focuses on three main issues. Firstly, it is argued that economists failed to predict the crisis and to design early warning systems. Secondly, it is claimed that economists use models of the macroeconomy which fail to integrate financial markets and which are inadequate to model large economic crises. Thirdly, the issue has been raised that economists invoke unrealistic assumptions concerning human behaviour by assuming that all agents are self-centred, rationally optimizing individuals. In this paper, we focus on the first two issues. Overall, our thrust is that the above statements are a caricature of modern economic theory and empirics. A rich field of research developed already before the crisis and picked up shortcomings of previous models.

On the Economics of Ex-Post Transfers in a Federal State: A Mechanism Design Approach
Martin Altemeyer-Bartscher, T. Kuhn
WWDP, 95,
No. 95,
2008
Abstract
As a common feature in many federal states grants-in aid are payed to jurisdictions ex post, i.e. after local policy measures have chosen. We show that the central government cannot offer grants ex ante in a federal states with informational asymmetries as well as inter-temporal commitment problems. Local governments’ incentives to provide public goods are distorted if they rely on federal grants-in-aid offered ex post. Furthermore it becomes obvious that local governments are apt to substitute tax revenue for higher grants-in-aid if relevant local data are unobservable for the central government. To which extend ex post transfers mitigate local governments’ incentives crucially depends on the information structure predominant in the federation.

Banks’ Internationalization Strategies: The Role of Bank Capital Regulation
Diemo Dietrich, Uwe Vollmer
IWH Discussion Papers,
No. 18,
2006
Abstract
This paper studies how capital requirements influence a bank’s mode of entry into foreign financial markets. We develop a model of an internationally operating bank that creates and allocates liquidity across countries and argue that the advantage of multinational banking over offering cross-border financial services depends on the benefit and the cost of intimacy with local markets. The benefit is that it allows to create more liquidity. The cost is that it causes inefficiencies in internal capital markets, on which a multinational bank relies to allocate liquidity across countries. Capital requirements affect this trade-off by influencing the degree of inefficiency in internal capital markets.

Currency Crisis Prediction Using ADR Market Data: An Options-based Approach
Stefan Eichler, Dominik Maltritz
International Journal of Forecasting,
No. 4,
2010
Abstract
During capital control episodes, large price deviations between American Depositary Receipts (ADR) and their underlying stocks signal that a currency crisis is about to occur. We interpret this price spread as the price of a call option. Using option pricing theory we derive detailed information about both the probability of a currency crisis and the expected magnitude of devaluation. Analyzing daily ADR market data preceding the Venezuelan crisis (1996), our approach predicts crisis probabilities of almost 100% and forecasts the exchange rate after floating quite accurately. During the Argentine crisis (2002), the estimated exchange rates are similar to the actual ones.

Prävention und Management von Staatsinsolvenzen in der Europäischen Währungsunion
Oliver Holtemöller, Tobias Knedlik
Wirtschaftsdienst,
2011
Abstract
Der Umgang mit den Schuldenkrisen in einigen Euroländern steht derzeit ganz oben auf der Tagesordnung der EWU-Gremien. Der Rettungsschirm zur aktuellen Krisenbewältigung ist allerdings bis 2013 befristet. Danach sollte ein dauerhafter Krisenpräventions- und Krisenmanagementmechanismus eingesetzt werden. Wie ein solcher Mechanismus zu gestalten ist, erläutern die Autoren in diesem Beitrag.

Staying, Dropping, or Switching: The Impacts of Bank Mergers on Small Firms
Hans Degryse, Nancy Masschelein, Janet Mitchell
Review of Financial Studies,
No. 4,
2011
Abstract
Assessing the impacts of bank mergers on small firms requires separating borrowers with single versus multiple banking relationships and distinguishing the three alternatives of “staying,” “dropping,” and “switching” of relationships. Single-relationship borrowers who “switch” to another bank following a merger will be less harmed than those whose relationship is “dropped” and not replaced. Using Belgian data, we find that single-relationship borrowers of target banks are more likely than other borrowers to be dropped. We track postmerger performance and show that many dropped target-bank borrowers are harmed by the merger. Multiple-relationship borrowers are less harmed, as they can better hedge against relationship discontinuations.

Enhancing Market Power by Reducing Switching Costs

Abstract
A proportional decrease in switching costs increases competition and social welfare. However, a lump-sum decrease in switching costs softens competition and does not invariably increase social welfare.

Credit Allocation and Value Creation of Banks: The Impact of Relationship Banking in Normal and Crisis-times
Hans Degryse, Steven Ongena
Revue d'économie financière,
No. 106,
2012
Abstract
Cet article passe en revue la littérature sur l’allocation de crédit et la création de valeur par les banques. Il se concentre sur l’activité de banque relationnelle, à savoir le fait qu’une banque et un emprunteur se lancent dans de multiples interactions et que chacun des deux agents s’efforce d’obtenir des informations spécifiques sur l’autre. Il montre comment la banque relationnelle génère des coûts et des bénéfices à la fois pour les entreprises et pour les banques, mais qu’en règle générale, elle est source de valeur pour chacun d’eux. Néanmoins, l’incidence de ce type de relation est en grande partie fonction du contexte économique (période normale ou période de crise). Est aussi abordée la manière dont l’allocation de crédit, mesurée par la spécialisation sectorielle, affecte les entreprises et les banques. Enfin, l’examen de la littérature récente en matière de titrisation et de relation bancaire permet de mettre en évidence la manière dont la titrisation affecte les effets de la banque relationnelle.

Foreign Bank Entry, Credit Allocation and Lending Rates in Emerging Markets: Empirical Evidence from Poland
Hans Degryse, Olena Havrylchyk, Emilia Jurzyk, Sylwester Kozak
Journal of Banking and Finance,
No. 11,
2012
Abstract
Earlier studies have documented that foreign banks charge lower lending rates and interest spreads than domestic banks. We hypothesize that this may stem from the superior efficiency of foreign entrants that they decide to pass onto borrowers (“performance hypothesis”), but could also reflect a different loan allocation with respect to borrower transparency, loan maturity and currency (“portfolio composition hypothesis”). We are able to differentiate between the above hypotheses thanks to a novel dataset containing detailed bank-specific information for the Polish banking industry. Our findings demonstrate that banks differ significantly in terms of portfolio composition and we attest to the “portfolio composition hypothesis” by showing that, having controlled for portfolio composition, there are no differences in lending rates between banks.
