Abstract
The important role of credit has long been identified as a key factor for economic development (see e.g. Wicksell (1898), Keynes (1931), Fisher (1933) and Minsky (1957, 1964)). Even before the financial crisis most researchers and policy makers agreed that financial frictions play an important role for business cycles and that financial turmoils can result in severe economic downturns (see e.g. Mishkin (1978), Bernanke (1981, 1983), Diamond (1984), Calomiris (1993) and Bernanke and Gertler (1995)). However, in practice researchers and policy makers mostly used simplified models for forecasting and simulation purposes. They often neglected the impact of financial frictions and emphasized other non financial market frictions when analyzing business cycle fluctuations (prominent exceptions include Kiyotaki and Moore (1997), Bernanke, Gertler, and Gilchrist (1999) and Christiano, Motto, and Rostagno (2010)). This has been due to the fact that most economic downturns did not seem to be closely related to financial market failures (see Eichenbaum (2011)). The outbreak of the subprime crises ― which caused panic in financial markets and led to the default of Lehman Brothers in September 2008 ― then led to a reconsideration of such macroeconomic frameworks (see Caballero (2010) and Trichet (2011)). To address the economic debate from a new perspective, it is therefore necessary to integrate the relevant frictions which help to explain what we have experienced during recent years.
In this thesis, I analyze different ways to incorporate relevant frictions and financial variables in macroeconometric models. I discuss the potential consequences for standard statistical inference and macroeconomic policy. I cover three different aspects in this work. Each aspect presents an idea in a self-contained unit. The following paragraphs present more detail on the main topics covered.

The GVAR Handbook: Structure and Applications of a Macro Model of the Global Economy for Policy Analysis
Filippo di Mauro, M. Hashem Pesaran
Oxford University Press,
2013
Abstract
The recent crisis has shown yet again how the world economies are globally interlinked, via a complex net of transmission channels. When it comes, however, to build econometric frameworks aimed at analysing such linkages, modellers are faced with what is called the "curse of dimensionality": there far too many parameters to be estimated with respect to the available observations. The GVAR, a VAR based model of the global economy, offers a solution to this problem. The basic model is composed of a large number of country specific models, comprising domestic, foreign and purely global variables. The foreign variables, however, are treated as weakly exogenous. This assumption, which is typically held when empirically tested for virtually all economies - with the notable exception of the US which is treated differently - allows to estimate first the individual country models separately. Only in a second stage country-specific models are simultaneously solved, thus allowing global interactions.This volume presents - for a first time in a compact and rather easy to read format - principles and structure of the basic GVAR model and a number of its many applications and extensions developed in the last few years by a growing literature. Its main objective is to show how powerful the model can be as a tool for forecasting and scenario analysis. The clear modelling structure of the GVAR appeals to policy makers and practitioners as shown by its growing use among major institutions, as well as by econometricians, as shown by the main extensions and applications.

Testing for Structural Breaks at Unknown Time: A Steeplechase
Makram El-Shagi, Sebastian Giesen
Computational Economics,
No. 1,
2013
Abstract
This paper analyzes the role of common data problems when identifying structural breaks in small samples. Most notably, we survey small sample properties of the most commonly applied endogenous break tests developed by Brown et al. (J R Stat Soc B 37:149–163, 1975) and Zeileis (Stat Pap 45(1):123–131, 2004), Nyblom (J Am Stat Assoc 84(405):223–230, 1989) and Hansen (J Policy Model 14(4):517–533, 1992), and Andrews et al. (J Econ 70(1):9–38, 1996). Power and size properties are derived using Monte Carlo simulations. We find that the Nyblom test is on par with the commonly used F type tests in a small sample in terms of power. While the Nyblom test’s power decreases if the structural break occurs close to the margin of the sample, it proves far more robust to nonnormal distributions of the error term that are found to matter strongly in small samples although being irrelevant asymptotically for all tests that are analyzed in this paper.

Central Bank, Trade Unions, and Reputation – Is there Room for an Expansionist Manoeuvre in the European Union?

A. Heise (ed.), Market Constellation Research: A Modern Governance Approach to Macroeconomic Policy. Institutionelle und Sozial-Ökonomie, Bd. 19,
2011
Abstract
The objective of this reader is manifold: On the one hand, it intends to establish a new perspective at the policy level named 'market constellations': institutionally embedded systems of macroeconomic governance which are able to explain differences in growth and employment developments. At the polity level, the question raised is whether or not market constellations can be governed and, thus, whether institutions can be created which will provide the incentives necessary for favourable market constellations.

An Evolutionary Algorithm for the Estimation of Threshold Vector Error Correction Models
Makram El-Shagi
International Economics and Economic Policy,
No. 4,
2011
Abstract
We develop an evolutionary algorithm to estimate Threshold Vector Error Correction models (TVECM) with more than two cointegrated variables. Since disregarding a threshold in cointegration models renders standard approaches to the estimation of the cointegration vectors inefficient, TVECM necessitate a simultaneous estimation of the cointegration vector(s) and the threshold. As far as two cointegrated variables are considered, this is commonly achieved by a grid search. However, grid search quickly becomes computationally unfeasible if more than two variables are cointegrated. Therefore, the likelihood function has to be maximized using heuristic approaches. Depending on the precise problem structure the evolutionary approach developed in the present paper for this purpose saves 90 to 99 per cent of the computation time of a grid search.

Africa and the Global Financial Crisis - Impact on Economic Reform Processes
R. Adelou Alabi, J. Alemazung, Achim Gutowski, Robert Kappel, Tobias Knedlik, O. Osnachi Uzor, Karl Wohlmuth, Hans H. Bass
African Development Perspectives Yearbook, Vol. 15,

Abstract
In volume XV of the African Development Perspectives Yearbook, the Research Group on African Development Perspectives investigates the impact of the GFC on economic reform processes in Africa. The analysis is structured in such a way so as to reflect the opportunities and dangers of policy reversals in the face of the GFC. The impact of the crisis on different types and forms of governance in the region is considered. The first question is therefore which macro-economic policy instruments have to be applied in order to overcome the crisis and to continue with sustainable development. The second question is how the GFC has affected Africa's external economic relations and if the path of opening up to the world markets is continued. The third question raised is how the crisis has affected social cohesion, impacted on poverty alleviation strategies and the achievement of Millennium Development Goals (MDGs). All these questions are discussed in the various contributions which comprise general studies and country case studies. The authors also looked into the role of international financial institutions during and after the crisis. The volume XV of the African Development Perspectives Yearbook is structured into three Units. Unit 1 addresses general issues regarding the impact of the GFC on reform processes in Africa. Unit 2 presents case studies from countries and sub-regions. Unit 3 presents reviews and book notes of current literature focusing on issues of African development perspectives.

Midterm Projection: Economic Development and the Public Budget in the Years 2011 - 2015
Kristina vanDeuverden, Rolf Scheufele
Wirtschaft im Wandel,
No. 1,
2011
Abstract
Die deutsche Wirtschaft hat sich im Jahr 2010 kräftig erholt. In der ersten Jahreshälfte zogen der Welthandel und in dessen Gefolge die deutschen Exporte kräftig an. Im Verlauf des Jahres wurde das Wachstum der Wirtschaft
in Deutschland aber zunehmend von der Binnennachfrage gestützt. Nicht nur die Investitionen erholten sich, auch vom privaten Konsum kamen Impulse. So liegt die Zahl der Beschäftigten zurzeit auf einem historischen Höchststand, und die Zahl der Arbeitslosen hat sich im Lauf des Jahres immer weiter zurückgebildet.
Auch mittelfristig wird das wirtschaftliche Wachstum in Deutschland verhältnismäßig hoch sein. Der deutsche Außenhandel erhält weiterhin Impulse vom Welthandel. Wesentlich wird die weitere Entwicklung allerdings von der Binnenwirtschaft bestimmt. So werden die Investitionen in der mittleren Frist deutlich expandieren. Dazu trägt bei, dass das Zinsniveau bis zum Ende des Projektionszeitraums relativ niedrig sein wird. Auch der private Konsum wird zum Wirtschaftswachstum beitragen. Die günstige Lage auf dem Arbeitsmarkt und der
hohe Beschäftigungsstand lassen die Lohnsumme kräftig zunehmen und erhöhen zudem den Grad an Beschäftigungssicherheit. Dies führt dazu, dass die privaten Haushalte ihre Konsumausgaben merklich erhöhen. Alles in allem wird das reale Bruttoinlandsprodukt im Jahr 2011 mit 2,3% und im Jahr 2012 mit 1,7% zulegen. In den Restjahren des Projektionszeitraums wird es mit 1½% steigen.

Worker Remittances and Capital Flows to Developing Countries
Claudia M. Buch, A. Kuckulenz
International Migration,
No. 5,
2010
Abstract
Worker remittances constitute an increasingly important channel for the
transfer of resources to developing countries. Behind foreign direct investment,
remittances are the second-largest source of external funding for developing countries. Yet, literature on worker remittances has traditionally focused on the impact of remittances on income distribution within countries, on the determinants of remittances at a micro-level, or on the effects of migration and remittances for specific countries or regions. Macroeconomic determinants and effects of remittances have received more attention only recently. Hence, the focus of this paper is on the macroeconomic determinants of remittances and on differences in these determinants between remittances and other capital flows. We find that
remittances respond more to demographic variables while private capital
flows respond more to macroeconomic conditions.
