Empirical Economics,
No. 1,
2020
Abstract
Economic forecasts are an important element of rational economic policy both on the federal and on the local or regional level. Solid budgetary plans for government expenditures and revenues rely on efficient macroeconomic projections. However, official data on quarterly regional GDP in Germany are not available, and hence, regional GDP forecasts do not play an important role in public budget planning. We provide a new quarterly time series for East German GDP and develop a forecasting approach for East German GDP that takes data availability in real time and regional economic indicators into account. Overall, we find that mixed-data sampling model forecasts for East German GDP in combination with model averaging outperform regional forecast models that only rely on aggregate national information.

Fiscal Policy and Fiscal Fragility: Empirical Evidence from the OECD
Makram El-Shagi, Gregor von Schweinitz
Abstract
In this paper, we use local projections to investigate the impact of consolidation shocks on GDP growth, conditional on the fragility of government finances. Based on a database of fiscal plans in OECD countries, we show that spending shocks are less detrimental than tax-based consolidation. In times of fiscal fragility, our results indicate strongly that governments should consolidate through surprise policy changes rather than announcements of consolidation at a later horizon.

Progressive Tax-like Effects of Inflation: Fact or Myth? The U.S. Post-war Experience
Matthias Wieschemeyer, Bernd Süssmuth
IWH Discussion Papers,
No. 33,
2017
Abstract
Inflation and earnings growth can push some tax payers into higher brackets in the absence of inflation-indexed schedules. Moreover, inflation may affect the composition of individuals’ income sources. As a result, depending on the relative tax burden of labour and capital, inflation may decrease or increase the difference between before-tax and after-tax income. However, whether some and if so which percentiles of the income distribution net benefit from inflation via taxation is a widely unexplored question. We make use of a novel dataset on U.S. pre-tax and post-tax income distribution series provided by Pike ty et al. (2018) for the years 1962 to 2014 to answer this question. To this end, we estimate local projections to quantify dynamic effects. We find that inflation shocks increase progressivity of taxation not only contemporaneously but also with some repercussion of several years after the shock. While particularly the bottom two quintiles gain in share, it is not the top but the fourth quintile that lastingly loses.

The German Economy: Economic Activity Spurred by Private Consumption and Construction
German economic activity remains robust due to strong domestic demand. IWH forecasts gross domestic product (GDP) to increase by 1.3% in 2017. The growth rate is half a percentage point lower than in 2016 due to calendar effects and a negative contribution of external trade. Consumer price inflation also remains modest (1.3%). “Unemployment is expected to increase slightly due to a protracted integration of refugees into the labor market”, says Oliver Holtemöller, Head of the Department Macroeconomics and IWH vice president

Much Ado About Nothing: Sovereign Ratings and Government Bond Yields in the OECD
Makram El-Shagi
IWH Discussion Papers,
No. 22,
2016
Abstract
In this paper, we propose a new method to assess the impact of sovereign ratings on sovereign bond yields. We estimate the impulse response of the interest rate, following a change in the rating. Since ratings are ordinal and moreover extremely persistent, it proves difficult to estimate those impulse response functions using a VAR modeling ratings, yields and other macroeconomic indicators. However, given the highly stochastic nature of the precise timing of ratings, we can treat most rating adjustments as shocks. We thus no longer rely on a VAR for shock identification, making the estimation of the corresponding IRFs well suited for so called local projections – that is estimating impulse response functions through a series of separate direct forecasts over different horizons. Yet, the rare occurrence of ratings makes impulse response functions estimated through that procedure highly sensitive to individual observations, resulting in implausibly volatile impulse responses. We propose an augmentation to restrict jointly estimated local projections in a way that produces economically plausible impulse response functions.

A Systemic View on Knowledge-based Development Metrics
Mirko Titze, Michael Schwartz, Matthias Brachert
International Journal of Knowledge-Based Development,
No. 1,
2012
Abstract
Drawing on the systems perspective of innovation processes, this article proposes a conceptual approach for a comprehensive analysis of regional knowledge generation and transfer. Instead of focusing on one single indicator, the approach emphasizes the importance to take multiple channels of knowledge transfer into account. This provides valuable insights into the spatial structure of innovation processes on different levels. We disentangle the innovation process and consider four different layers: i.) publications in peer-reviewed journals, ii.) patent applications, iii.) formal R&D collaboration projects, the iv.) localized input-output relations. Further, we demonstrate the relevance of the „multi-layer approach‟ by applying it empirically to a specific regional innovation system: The Free State of Saxony – a federal state in Germany. We argue that the approach could be a valuable tool to inform policy-makers about knowledge-based regional development strategies.

Economic Effects of Investment Grants for Water and Sewerage Infrastructure – The Case of Saxony
Peter Haug
Wirtschaft im Wandel,
No. 11,
2010
Abstract
The article deals with the regional economic growth effects of the German “Joint Scheme” for the improvement of regional economic structures (“GA-Infra”). It focuses on water and sewerage projects located in the federal state of Saxony (Germany) during the funding period 2000-2007. Evaluating these projects is important for scientific as well as for economic policy reasons.
First of all, according to general economic theory, the potential direct and indirect supply-side effects of the water and sewerage infrastructure as well as the price effects caused by this infrastructure are relevant for location decisions only to certain branches of the manufacturing industry.
Subsidies for the development of the sewerage infrastructure have been granted mostly according to the growth target of regional policy, i.e. primarily to municipalities with above-average volumes of industry sewage. This finding could not be confirmed for water provision.
A regression analysis (estimating the labour demand of the local manufacturing industry) showed no empirical evidence for any relationship between the changes in labour demand and the amount of GA-Infra funded water and sewerage infrastructure investments. This might be a consequence of the already satisfactory development condition of the infrastructure in question at the beginning of the funding period (“ubiquitous infrastructure”).
According to a survey of local governments conducted by the IWH, these results might be explained by the fact that business customers did not benefit from price reductions despite the GA-Infra funding granted to their local water and sewage disposal providers. Even though there might be some intuitively plausible reasons (decreasing population, no connection fees) for these findings, no effect on firm location decisions can be expected under these circumstances.
All in all, we do not consider the further extension of these funding priorities to be necessary. Especially, the GA-Infra water/sewerage grants should neither be used to mitigate the cost effects of demographic changes or regulation nor to compensate for losses caused by the buyer power of large firms.

What are the Long-Term Benefits of the Economic Stimulus Package II for German Local Governments? – The Case of Saxony
Peter Haug
Wirtschaft im Wandel,
No. 4,
2010
Abstract
This article deals with the question whether the investments subsidized by the economic stimulus package II („Konjunkturpaket II“) do not only have short-term effects on demand but also long-term effects e.g. on local economic growth. As far as the short-term effects are concerned, the case of the German state of Saxony shows – with some delay – a rise in local government´s investments. Hence, the time-lag problem inherent in all governmental spending programmes seems to keep within reasonable limits. Up to now there have been no signs of inflationary price tendencies in the construction sector.
According to - for example - the „new“ economic growth theory, one ought to be sceptical about the long-term effects of the projects supported by the programme: Even for genuine public intermediate goods the withdrawal effects of financing have to be weighed against the positive effects on private enterprise sector productivity. Furthermore, the effects on factor prices caused by the investment grants might encourage the excess use of physical capital in public production.
This sceptical attitude of the theory is confirmed for Saxony by the fact that primarily public consumption goods (sports and leisure facilities) or educational facilities (kindergartens, primary schools), which are of no direct relevance to the local enterprises, are supported by the programme. Investments in vocational training, research and development play only a minor role at the local government level or are explicitly excluded from the programme.
Especially because of the incentives to misallocate public resources it is recommended to rely on unconditional grants in future support programmes. Then the local governments could use the grants for either „investments” in human capital (new [fixed-term contract] hires, qualification) or in physical capital, according to their needs.

New Growth and Poverty Alleviation Strategies for Africa – Institutional and Local Perspectives. African Development Perspectives Yearbook, Vol. 14
Tobias Knedlik, Karl Wohlmuth, Philippe Burger, Achim Gutowski, Mareike Meyn, T. (eds) Urban, Afeikhena Jerome
,
2009
Abstract
The Volume XIV analyses the “New Growth and Poverty Alleviation Strategies for Africa“. Institutional issues and perspectives in designing new growth and poverty alleviation strategies are considered in various case studies (Cote d'Ivoire, Nigeria, Botswana and Tanzania). Other studies deal with institutional problems of resource-rich countries after conflict (Sudan) and with the institutions to enhance environmental protection parallel to economic growth and poverty reduction (Niger). Further studies deal with institutions to bridge the gap between formal and informal entrepreneurial sectors in Kenya and Tanzania. Local issues and perspectives for designing new growth and poverty alleviation strategies are considered in case studies on rural-urban development gaps in Tanzania and on microfinance as an instrument for new growth and poverty alleviation strategies (Tanzania and Eritrea). A study on small farmers in Ghana provides information on the role they can play in value chains. Two studies on Nigeria highlight the local and the sub-regional health and poverty alleviation programmes and the relation to growth. Book reviews and book notes on the theme are part of the volume. This volume builds the foundation for a comprehensive strategy of policy reforms in Africa so as to integrate new growth and poverty alleviation strategies. Complementary to Volume XIV is Volume XIII on “New Growth and Poverty Alleviation Strategies for Africa - Interational and Regional Perspectives“. Both volumes are of importance for all those who work in African countries as officials, executives, managers, researchers, and policy-makers, but also for all those who actively support Africa's development concerns at the international, regional, country, local, and project levels. They will experience this Volume XIV and also the complementary Volume XIII as indispensable sources of insight, reference, and inspiration.
