Determinants of Evolutionary Change Processes in Innovation Networks – Empirical Evidence from the German Laser Industry
Muhamed Kudic, Andreas Pyka, Jutta Günther
Abstract
We seek to understand the relationship between network change determinants, network change processes at the micro level and structural consequences at the overall network level. Our conceptual framework considers three groups of determinants – organizational, relational and contextual. Selected factors within these groups are assumed to cause network change processes at the micro level – tie formations and tie terminations – and to shape the structural network configuration at the overall network level. We apply a unique longitudinal event history dataset based on the full population of 233 German laser source manufacturers and 570 publicly-funded cooperation projects to answer the following research question: What kind of exogenous or endogenous determinants affect a firm’s propensity and timing to cooperate and enter the network? Estimation results from a non-parametric event history model indicate that young micro firms enter the network later than small-sized and large firms. An in-depth analysis of the size effects for medium-sized firms provides some unexpected yet quite interesting findings. The choice of cooperation type makes no significant difference for the firms’ timing to enter the network. Finally, the analysis of contextual determinants shows that cluster membership can, but do not necessarily, affect a firm’s timing to cooperate.

Fiscal Spending Multiplier Calculations Based on Input-Output Tables? An Application to EU Member States

Intervention. European Journal of Economics and Economic Policies,
No. 1,
2012
Abstract
Fiscal spending multiplier calculations have attracted considerable attention in the aftermath of the global financial crisis. Much of the current literature is based on VAR estimation methods and DSGE models. In line with the Keynesian literature we argue that many of these models probably underestimate the fiscal spending multiplier in recessions. The income-expenditure model of the fiscal spending multiplier can be seen as a good approximation under these circumstances. In its conventional form this model suffers from an underestimation of the multiplier due to an overestimation of the import intake of domestic absorption. In this article we apply input-output calculus to solve this problem. Multipliers thus derived are comparably high, ranging between 1.4 and 1.8 for many member states of the European Union. GDP drops due to budget consolidation might therefore be substantial in times of crisis.

Pre-announcement and Timing: The Effects of a Government Expenditure Shock
Alexander Kriwoluzky
European Economic Review,
No. 3,
2012
Abstract
An econometric strategy to identify a pre-announced fiscal policy shock is proposed. I show that the reduced form innovations can be recovered by estimating a Vector-moving-average model using the Kalman filter. The structural effects are identified exploiting the shock's pre-announced nature, which leads to potentially different signs of the responses of some endogenous variables during the announcement and after the realization of the shock. I illustrate my strategy by identifying a pre-announced shock to government consumption expenditures. I find that the response of private consumption is significantly negative on impact, rises and becomes significantly positive two quarters after the realization of the policy shock.

Fiscal Policy and the Great Recession in the Euro Area
Mathias Trabandt, Günter Coenen, Roland Straub
American Economic Review: Papers and Proceedings,
No. 3,
2012
Abstract
How much did fiscal policy contribute to euro area real GDP growth during the Great Recession? We estimate that discretionary fiscal measures have increased annualized quarterly real GDP growth during the crisis by up to 1.6 percentage points. We obtain our result by using an extended version of the European Central Bank's New Area-Wide Model with a rich specification of the fiscal sector. A detailed modeling of the fiscal sector and the incorporation of as many as eight fiscal time series appear pivotal for our result.

The Financial Crisis from a Forecaster's Perspective
Katja Drechsel, Rolf Scheufele
Kredit und Kapital,
No. 1,

Abstract
This paper analyses the recession in 2008/2009 in Germany. This recession is very different from previous recessions in particular regarding their causes and magnitude. We show to what extent forecasters and forecasts based on leading indicators fail to detect the timing and the magnitude of the recession. This study shows that large forecast errors for both expert forecasts and forecasts based on leading indicators resulted during this recession which implies that the recession was very difficult to forecast. However, some leading indicators (survey data, risk spreads, stock prices) have indicated an economic downturn and hence, beat univariate time series models. Although the combination of individual forecasts provides an improvement compared to the benchmark model, the combined forecasts are worse than several individual models. A comparison of expert forecasts withthe best forecasts based on leading indicators shows only minor deviations. Overall, the range for an improvement of expert forecasts in the crisis compared to indicator forecasts is small.

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.

Regional Determinants of MNE´s Location Choice in Transition Economies
Andrea Gauselmann, Philipp Marek
WIFO Working Papers,
No. 412,
2011
published in: Empirica
Abstract
The article at hand analyses the impact of agglomeration effects, labour market conditions and other determinants on the location choice of MNEs in transition economies. We compare data from 33 regions in East Germany, the Czech Republic and Poland using a conditional logit model on a sample of 4,343 subsidiaries for the time period between 2000 to 2010. The results show that agglomeration advantages, such as sectoral specialization, a certain economic diversity as well as a region’s economic and technological performance prove to be some of the most important pull factors for FDI in transition regions. In addition, the labour market factors prove to play an important role in the location of FDI.

International Fragmentation of Production and the Labour Input into Germany’s Exports – An Input-Output-analysis
Hans-Ulrich Brautzsch, Udo Ludwig
IWH Discussion Papers,
No. 14,
2011
Abstract
The import penetration of exports has become a topic of public debate, particularly in the context of Germany’s position as one of the world’s leading exporters. The growth in the volume of intermediate products purchased from abroad for subsequent processing into export goods in Germany seems to be undermining the importance of exports as a driver of domestic production and employment. The gains that arise from an increase in exports seem to have been offset by the losses caused by the crowding out of local production by imports. Empirical evidence on the impact of this international integration of the goods market on the German labour market is ambiguous. Short-term negative effects on employment are claimed to be offset by the long-term benefit that the jobs lost in the short run will eventually be replaced by higher-skilled jobs with better
perspectives. Against this background, the following hypothesis is tested empirically: Germany is poor in natural resources, but rich in skilled labour. In line with the Heckscher- Ohlin theory, Germany should therefore specialize in the production of export goods and services that are relatively intensive in these factors and should import those goods and services that are relatively intensive in unskilled labour. The empirical part of the paper deals with the extent of the German export penetration by imports. At first, it analyses by what ways imports are affecting the exports directly and indirectly and shows the consequences of import penetration of exports for the national output and employment. Secondly, consequences for employment are split in different skill types of labour. These issues are discussed with the standard open static inputoutput- model. The data base is a time series of official input-output tables. The employment effects for Germany divided by skill types of labour are investigated using skill matrices generated by the authors.

An Economic Life in Vain − Path Dependence and East Germany’s Pre- and Post-Unification Economic Stagnation
Ulrich Blum
IWH Discussion Papers,
No. 10,
2011
Abstract
20 Jahre nach dem Vollzug der Einheit stagniert die Wirtschaftsentwicklung des „ostdeutschen Zwillings“ im Vergleich zu westdeutschen Einkommens- und Produktionskennzahlen. Der starke Wachstumsschub bis in die Mitte der 1990er Jahre ebbte ab, und die Wirtschaft verharrt seitdem auf einem Niveau, das 70% bis 80% der westdeutschen Referenzgrößen entspricht. In diesem Beitrag werden zwei voneinander unabhängige Hypothesen überprüft: (i), dass bereits die kommunistische Wirtschaft Ostdeutschlands vor der Einheit auf einem Stagnationspfad war, ganz im Gegensatz zu dem, was andere Untersuchungen ausweisen; (ii), dass eine starke Pfadabhängigkeit existiert und der Umstieg von der Zentralverwaltungs- zur Marktwirtschaft nur diese vorangegangene Stagnationsphase kompensierte, die tiefer liegenden strukturellen Defizite aber nicht löste. Im Falle Westdeutschlands reicht ein stabiler Entwicklungspfad vom 19. Jahrhundert in die Gegenwart. Daher ist die Analyse des ostdeutschen Entwicklungspfads gleichzeitig ökonomisch relevant und wirtschaftspolitisch bedeutsam.
