Estimating Monetary Policy Rules for South Africa
Tobias Knedlik
South African Journal of Economics,
2006
Abstract
The paper combines the estimation of the Monetary Conditions Index (MCI) with the theoretic modelling of optimal monetary policy in South Africa. The idea that monetary policy is not only interested in optimal monetary conditions but also in external stability, provides the basis for the analysis. The paper introduces the concept of the MCI and estimates the relative influence of interest rates and exchange rates on the output gap. The estimated weights are 1.9:1. This estimation result is used to specify operating target rules for South African monetary policy.

Interregional equalization policy in focus: Donor regions and beneficiary regions and their economic performance
Gerhard Heimpold, Peter Franz
Wirtschaft im Wandel,
No. 11,
2006
Abstract
The future of the interregional equalization policy in Germany is discussed intensively at present. While in the past the interest of equalization policy was focussed primarily on the regions which benefit from interregional equalization policy (beneficiary regions) and the effects obtained there, recently the view is directed also toward the regions which bear the fiscal burden of the equalisation policy (donor regions). Concerning the donor regions, a fear of growth-absorbing withdrawal effects exists, which gives reason in view of declining economic growth rates on the national level to think about the future of interregional equalization policy. The IWH contributed to this debate together with two project partners by an investigation, which was accomplished on behalf of the Federal Office for Building and Regional Planning. The following findings will show the economic performance of the donor regions (exclusively West German regions) and of the beneficiary regions (all East German regions and a few West German regions) and their changing economic growth patterns. Concerning the level of economic performance, measured by means of the gross domestic product (GDP) per capita, as expected, the donor regions, consisting of West German regions, in the period 1992-2003 altogether show an above average GDP per capita. In contrast, the beneficiary regions, both the East German and (less strongly) the West German show a GDP per capita below average. Concerning the development of the economic performance, which was measured on the basis of the relative GDP per capita (GDP per capita of the region concerned in relation to the national average), the East German beneficiary regions could catch up in the first period (1992-1998) strongly. This catching up process, however, clearly slowed down in the second period 1998-2003. Like a mirror-image the lead of the donor regions regarding GDP per capita in relation to the national average became smaller. But after 1998 many West German donor regions regained their growth dynamics. Additionally the contributions of the regions to the absolute increase of the GDP in the period 1998-2003 were investigated: 30 of 271 regions have a share of around 50% in the overall GDP increase, 28 of them located in West Germany, and 21 of them donor regions. This in mind, the policy should further provide and secure favourable development conditions for those regions, which contribute at most to the increase of the overall economic performance and thus create the economic base for the interregional equalization policy.

Do House Prices Drive Aggregate Consumption?
Marian Berneburg, Axel Lindner
Wirtschaft im Wandel,
No. 10,
2006
Abstract
In recent times increasing house prices have been credited with a stong positive influence on aggre-gate consumption. But it is questionable in how far higher prices are at all able to lift the purchasing power of the economy as whole: The seller’s profit of a high price, equals the buyer’s loss. But while a positive correlation between house prices and consumption is evident, it is not a sign of irra-tional behaviour by market participants. In fact it seems that both factors are driven by other pa-rameters: the interest rate and expectations about future interest rates and economic activity. For a selection of four developed countries, the follow-ing article tries to give an explanation for the house price developments of the past 15 years. While disregarding country specific risk as well as institutional aspects and demographic factors, a present value caluclation forms the basis for esti-mating a fundamentally justified price movement. Expectations for future rents and discount rates are being proxied by a moving average of past values. It can be observed how interest rate changes and long-run economic growth, two as-pects that clearly also drive private consumption, play a key role here.

Money and Credit Market Integration in an enlarging Euro Zone: Methodological Issues
Johannes Stephan, Jens Hölscher
European Economic Policies - Alteratives to Orthodox Analysis and Policy Concepts,
2006
Abstract
“The chapter discusses methodological issues of money and credit market integration within the context of an enlarging Euro area. Common methods of interest parity tests are rejected in favour of a comparison of nominal interest rates. Hölscher and Stephan find that from an institutional point of view the new EU member countries look under-banked, whereas interest rates are converging. As policy implication the paper argues for a Euro adoption of the new EU members rather sooner than later.“

The IWH signals approach: the present potential for a financial crisis in selected Central and East European countries and Turkey
Hubert Gabrisch, Simone Lösel
Wirtschaft im Wandel,
No. 8,
2006
Abstract
The steep increase of oil prices, general threats rooting from Iran’s nuclear program, and doubts about the future policy of important central banks recently caused more uncertainties of investors on international financial markets. This explains the higher volatility and the fall of indices on stock markets including those of some Central and East European countries. International investors could respond with adjustments of their portfolio and trigger off a financial crisis. On this background, the article studies the potential for a financial crises in the region mentioned. The analytical tool is the IWH signals approach. The study concludes that the risk of the outbreak of a financial crisis within the next 18 months is rather unrealistic in most countries. A stable economic policy, high real growth rates, a financial system already robust compared to earlier times of transition, and appropriate exchange rate arrangements protect the countries against speculative attacks and portfolio adjustments. When the composite indicator shows deterioration like in the Baltic countries, it turned out to be negligible. For the Slovak Republic and Slovenia, the composite indicator even improved. A closer look to individual indicators reveals still some problems in the banking sectors of the Czech Republic, Poland, and Hungary, however, without out major impact on the composite indicator.
This general assessment does not apply to Romania, and, in particular, to Turkey. The composite indicator signals a significant increase of the risk potential for the next 18 months in both countries. There is a considerable need for sound policy action.

Excess Volatility in European Equity Style Indices - New Evidence
Marian Berneburg
IWH Discussion Papers,
No. 16,
2006
Abstract
Are financial markets efficient? One proposition that seems to contradict this is Shiller’s finding of excess volatility in asset prices and its resulting rejection of the discounted cash flow model. This paper replicates Shiller’s approach for a different data set and extends his analysis by testing for a long-run relationship by means of a cointegration analysis. Contrary to previous studies, monthly data for an integrated European stock market is being used, with special attention to equity style investment strategies. On the basis of this analysis’ results, Shiller’s findings seem questionable. While a long-run relationship between prices and dividends can be observed for all equity styles, a certain degree, but to a much smaller extent than in Shiller’s approach, of excess volatility cannot be rejected. But it seems that a further relaxation of Shiller’s assumptions would completely eliminate the finding of an overly strong reaction of prices to changes in dividends. Two interesting side results are, that all three investment styles seem to have equal performance when adjusting for risk, which by itself is an indication for efficiency and that market participants seem to use current dividend payments from one company as an indication for future dividend payments by other firms. Overall the results of this paper lead to the conclusion that efficiency cannot be rejected for an integrated European equity market.

Unternehmensbewertung, Rating und Risikobewältigung
Ulrich Blum, Werner Gleißner
Wissenschaftliche Zeitschrift der Technischen Universität Dresden,
2006
Abstract
We inquire into the possibilities to improve the stability of the firms by better managing risk. We propose to directly link risk management to rating, i.e. the ability to meet future financial obligations. Principal elements of rating methodology are discussed against the background of risk management. Next to the rating mark the risk-related requirements for equity become the central measure for risk. Firms must balance the costs of improving their rating against the gains of an improved rating. Risk management is a major driver to improve shareholder value. Risk aggregation is the dominant method that uses information from risk management and synthesizes unique measure of value.

Are Botswana and Mozambique ready for CMA enlargement?
Tobias Knedlik
Botswana Journal of Economics,
No. 3,
2006
Abstract
The paper elaborates on the appropriateness of a potentially enlarged Common Monetary Area in Southern Africa including Botswana and Mozambique. The theory of optimum currency areas including some extensions by accounting for costs of non-integration and considering the external relations of currency areas are presented. Various indicators such as the structure of the economies, interest rates, inflation rates, exchange rates, factor mobility and trading partners are observed empirically. The paper concludes that current changes in the exchange rate policy of Botswana are expected to lead to increasing, though already high, convergence with CMA countries. Botswana is therefore an appropriate candidate for CMA enlargement. Mozambique is converging towards South Africa but still remains on a lower level. Taking into account the costs of non-integration, however, the target of integration should be formulated for the medium term.

Armut von jungen Erwachsenen in der Bundesrepublik
Eva Reinowski, Christine Steiner
Vierteljahreshefte zur Wirtschaftsforschung,
No. 1,
2006
Abstract
In recent years the youth unemployment rate increased rapidly in Germany and reached the European average. Unemployment is considered as the main poverty risk. But even though the share of social benefit receivers among the youths is above average, youth poverty - unlike child poverty - has been neglected in recent research. Regarding youth, poverty is seen more as a temporary phenomenon. Considering only the standard poverty measure is not enough to figure youth poverty, because one would neglect the personal income situation of the youths. The article´s aim is to combine the equivalised household income and the individual income to find most effected young people. In a further step the socio-demographic factors of those persons are included to draw a more precise picture of the circumstances of poor young people in Germany. The analysis is based on the German Micro Census 2002.

Determinants of employment - the macroeconomic view
Christian Dreger, Heinz P. Galler, Ulrich (eds) Walwai
Schriften des IWH,
No. 22,
2005
Abstract
The weak performance of the German labour market over the past years has led to a significant unemployment problem. Currently, on average 4.5 mio. people are without a job contract, and a large part of them are long-term unemployed. A longer period of unemployment reduces their employability and aggravates the problem of social exclusion.
The factors driving the evolution of employment have been recently discussed on the workshop Determinanten der Beschäftigung – die makroökonomische Sicht organized jointly by the IAB, Nuremberg, and the IWH, Halle. The present volume contains the papers and proceedings to the policy oriented workshop held in November 2004, 15-16th. The main focus of the contributions is twofold. First, macroeconomic conditions to stimulate output and employment are considered. Second, the impacts of the increasing tax wedge between labour costs and the take home pay are emphasized. In particular, the role of the contributions to the social security system is investigated.
In his introductory address, Ulrich Walwei (IAB) links the unemployment experience to the modest path of economic growth in Germany. In addition, the low employment intensity of GDP growth and the temporary standstill of the convergence process of the East German economy have contributed to the weak labour market performance. In his analysis, Gebhard Flaig (ifo Institute, München) stresses the importance of relative factor price developments. A higher rate of wage growth leads to a decrease of the employment intensity of production, and correspondingly to an increase of the threshold of employment. Christian Dreger (IWH) discusses the relevance of labour market institutions like employment protection legislation and the structure of the wage bargaining process on the labour market outcome. Compared to the current setting, policies should try to introduce more flexibility in labour markets to improve the employment record. The impact of interest rate shocks on production is examined by the paper of Boris Hofmann (Deutsche Bundesbank, Frankfurt). According to the empirical evidence, monetary policy cannot explain the modest economic performance in Germany. György Barabas and Roland Döhrn (RWI Essen) have simulated the effects of a world trade shock on output and employment. The relationships have been fairly stable over the past years, even in light of the increasing globalization. Income and employment effects of the German tax reform in 2000 are discussed by Peter Haan and Viktor Steiner (DIW Berlin). On the base of a microsimulation model, household gains are determined. Also, a positive relationship between wages and labour supply can be established. Michael Feil und Gerd Zika (IAB) have examined the employment effects of a reduction of the contribution rates to the social security system. To obtain robust results, the analysis is done under alternative financing scenarios and with different macroeconometric models. The impacts of allowances of social security contributions on the incentives to work are discussed by Wolfgang Meister and Wolfgang Ochel (ifo München). According to their study, willingness to work is expected to increase especially at the lower end of the income distribution. The implied loss of contributions could be financed by higher taxes.
