Abstract
Das neoklassische Wachstumsmodell von Solow aus dem Jahr 1956 gehört heute immer noch zu den wichtigsten Wachstumstheorien. Die heute gelehrten Formen, die sich in nahezu allen volkswirtschaftlichen Lehrbüchern befinden, verletzen jedoch einen wichtigen Zusammenhang aus der volkswirtschaftlichen Gesamtrechnung: die Identität von Nettoinvestitionen und Ersparnis. Die Lösungen der Lehrbuchmodelle widersprechen damit der ursprünglichen Solow-Lösung. Der vorliegende Beitrag zeigt die Konsequenzen dieser Ungenauigkeiten auf. Darüber hinaus wird ein Modell präsentiert, das die Identität von Nettoinvestitionen und Ersparnis wahrt und folglich mit der Solow-Lösung vereinbar ist.

Fiscal economy potentials of a county structure reform in Saxony-Anhalt
Simone Scharfe
Wirtschaft im Wandel,
No. 5,
2006
Abstract
In view of the foreseeable demographic and finance-political developments the public house holds of Eastern Germany are under considerable strain to consolidate. This applies particularly to Saxony-Anhalt and there especially to local authorities. In 2003 the municipal expenses level (running material expenses and personnel expenses) of counties and communities in Saxony-Anhalt amounted 1,015 Euro per inhabitant and was clearly higher than the other East German states. Beyond the means of economisation through the efficient application of public funds, considerations are given to the potentials of country structure reforms. In the last legislative period, the CDU/FDP government already established the amalgamation of 24 counties to eleven new ones with the bill of 11.11.2005. The SPD - as an oppositional party at that time - submitted a proposal for an even further-reaching structural change with a concentration to five counties. This article comprises an estimation of the fiscal economisation potentials of both versions. In the first step, the (long term accessible) county expense levels of Saxony-Anhalt within the scope of the existing structure of a county is determined with the help of a Benchmarkanalysis. These results are then compared with expected expense levels of a reformed county structure which leads to the saving effect of the respective county reform. In the result of the analysis it appears that the suggestion of the SPD to the county structure reform allows to expect clearly higher saving effects than the suggestion of the former CDU/FDP government, a strong meaning of the already enforced community administrative reform is imputable.

Heterogeneity in Lending and Sectoral Growth: Evidence from German Bank-level Data
A. Schertler, Claudia M. Buch, N. von Westernhagen
International Economics and Economic Policy,
2006
Abstract
This paper investigates whether heterogeneity across firms and banks matters for the impact of domestic sectoral growth on bank lending. We use several bank-level datasets provided by the Deutsche Bundesbank for the 1996–2002 period. Our results show that firm heterogeneity and bank heterogeneity affect how lending responds to domestic sectoral growth. We document that banks’ total lending to German firms reacts pro-cyclically to domestic sectoral growth, while lending exceeding a threshold of €1.5 million to German and foreign firms does not. Moreover, we document that the response of lending depends on bank characteristics such as the banking groups, the banks’ asset size, and the degree of sectoral specialization. We find that total domestic lending by savings banks and credit cooperatives (including their regional institutions), smaller banks, and banks that are highly specialized in specific sectors responds positively and, in relevant cases, more strongly to domestic sectoral growth.

The coalition treaty from a fiscal point of view
Kristina vanDeuverden
Wirtschaft im Wandel,
No. 12,
2005
Abstract
After weeks of negotiations the coalition finally agreed on the conditions for their political work. Not surprisingly, the coalition agreement is complex and intransparent – with a multitude of single measures far away from a precise definition. Quantifying the programme and estimating resulting cash flows is currently difficult; official calculations are – if at all – only partly available. Anyhow, the contract will form the basis for economic policy during the next four years; therefore its evaluation by now is indispensable. The thin red line of the agreement – not astonishingly when considering the precarious financial situation of the public sector – is consolidation. However, more than 80% of the consolidation volume results from the revenue side. Though one third of this is due to the cutback of tax exemptions, the lion’s share comes from raising tax rates, mainly the VAT standard rate. In contrast, cutting back public expenditure is minor and the agreement clearly comes short of the Koch/Steinbrück proposal; even new tax reliefs are created. The consolidation is almost completely borne by private households. Enterprises as a whole are barely hit. However, they have to wait until 2008 for a reform of company taxation – one of the most pressing problems in this legislative period. To reduce the companies tax burden until the reform starts the conditions for tax depreciation are temporarily relaxed. Anyway, from an international point of view the statutory tax rate is an important signal to enterprises deciding where to invest. Lowering effective tax rates by changing depreciation conditions is intransparent and, thus, will be less effective. Furthermore savings within the public sector are planned to accomplish consolidation; 10 billion Euro should result from efficiency gains and reduced expenditure. Consolidation measures mainly focus on the budget of the federal government. However, Länder and communities will participate in the additional tax revenues. In contrast, social securities will loose – and therefore also the share of employment that is subject to social insurance contribution. Particularly the unemployment insurance will be burdened by the decrease of its premium rate. Besides, the federal government will reduce its grants to the pension funds and most notably the health system. The contract is dominated by fiscal constraints. Cyclical requirements are considered only cursory and pressing structural reforms are put off. The reforms of company’s taxation, of fiscal federalism, of the health system as well as a proceeding reform of the labour market are only proposed. How and when measures in these fields are realised will determine whether fiscal policy can set a new course.

Determinants and Effects of Foreign Direct Investment: Evidence from German Firm-Level Data

Economic Policy,
No. 41,
2005
Abstract
Foreign direct investment is an essential aspect of ‘globalization’ yet its empirical determinants are not well understood. What we do know is based either on poor data for a wide range of nations, or good data for the US and Swedish cases. In this paper, we provide evidence on the determinants of the activities of German multinational firms by using a newly available firm-level data set from the Deutsche Bundesbank. The specific goal of this paper is to demonstrate the relative role of country-level and firm-level determinants of foreign direct investment. We focus on three main questions: First, what are the main driving forces of German firms’ multinational activities? Second, is there evidence that sector-level and firm-level factors shape internationalization patterns? Third, is there evidence of agglomeration effects in the foreign activities of German firms? We find that the market access motive for internationalization dominates. Firms move abroad mainly to gain better access to large foreign markets. Cost-saving motives, however, are important for some manufacturing sectors. Our results strongly suggest that firm-level heterogeneity has an important influence on internationalization patterns – as stressed by recent models of international trade. We also find positive agglomeration effects for the activities of German firms that stem from the number of other German firms that are active on a given foreign market. In terms of lessons for economic policy, our results show that lowering barriers to the integration of markets and encouraging the formation of human capital can promote the activities of multinational firms. However, our results related to the heterogeneity of firms and agglomeration tendencies show that it might be difficult to fine-tune policies directed at the exploitation of synergies and at the creation of clusters of foreign firms.

Sind Haushalte mit Wohneigentum sparsamer als Mieterhaushalte?
Ruth Grunert
IWH Discussion Papers,
No. 171,
2003
Abstract
In this paper examines the data of the income and consumption survey of 1998 with regard to savings and wealth. Households owning their property (owner households) and households renting the property (tenant households) are analysed seperatly and then compared. For further insight these two groups are also devided into East and West German households. In 1998, almost half of the West German and almost a quarter of the East German private households owned property they occupied themselves. The average owner household saves a monthly amount three times as large as the tenant household. The decisive economizing motive for the owner households is servicing its mortgages and loans. However, at the same time, there is the necessity to form reserves for the property maintainance as well as the renovation. In comparison to tenant households, owner households which no longer have to service mortgages or loans, have a higher average rate of saving. The estimate of the saving by means of regression analysis confirms the significant positive influence of the “owner” status on savings. However, in every estimate the houshold’s income proves to be the main influence on savings activity.

Bank Concentration and Retail Interest Rates
S. Corvoisier, Reint E. Gropp
Journal of Banking and Finance,
No. 11,
2002
Abstract
The recent wave of mergers in the euro area raises the question whether the increase in concentration has offset the increase in competition in European banking through deregulation. We test this question by estimating a simple Cournot model of bank pricing. We construct country and product specific measures of bank concentration and find that for loans and demand deposits increasing concentration may have resulted in less competitive pricing by banks, whereas for savings and time deposits, the model is rejected, suggesting increases in contestability and/or efficiency in these markets. Finally, the paper discusses some implications for tests of the effect of concentration on monetary policy transmission.
