Abstract
In this paper we test the ability of three of the most popular methods to forecast the South African currency crisis of June 2006. In particular we are interested in the out-ofsample performance of these methods. Thus, we choose the latest crisis to conduct an out-of-sample experiment. In sum, the signals approach was not able to forecast the outof- sample crisis of correctly; the probit approach was able to predict the crisis but just with models, that were based on raw data. Employing a Markov-regime-switching approach also allows to predict the out-of-sample crisis. The answer to the question of which method made the run in forecasting the June 2006 currency crisis is: the Markovswitching approach, since it called most of the pre-crisis periods correctly. However, the “victory” is not straightforward. In-sample, the probit models perform remarkably well and it is also able to detect, at least to some extent, out-of-sample currency crises before their occurrence. It can, therefore, not be recommended to focus on one approach only when evaluating the risk for currency crises.

For a Sustainable Contribution Rate of the Statutory Unemployment Insurance
Ingmar Kumpmann
Wirtschaft im Wandel,
No. 11,
2007
Abstract
The German Federal Government has decided to decrease the contribution rate of the statutory unemployment insurance from 4.2 to 3.3 per cent of gross wages. The unemployment insurance retards the income loss in times of increasing unemployment, which has a dampening effect on the business cycle. In order not to countervail this effect it is necessary to hold the contribution rate stable over times with high and low unemployment. Therefore, the budget surplus of the unemployment insurance agency in the current economic upswing is no sufficient argument for a contribution cut. A present reduction of the contribution rate induces the risk of a new contribution rise in the next economic slowdown. It would be better to build up sufficient reserves so that a contribution rise will be avoidable even in times with increasing unemployment.

The German Upswing Takes a Break
Wirtschaft im Wandel,
2. Sonderausgabe
2007
Abstract
The world economy continues to expand healthily, but risks have increased during summer. The crisis of the housing sector in the US has deepened: A revaluation of mortgage backed assets has triggered turbulences on global financial markets. The institutes expect that financial markets will calm down during the coming months, but that the downswing in the US will slow the pace of the world economy. The economy in the euro area will, in addition, be dampened by the appreciation of the euro. The German economy is, in spite of a restrictive fiscal policy, in a robust upswing. Because wage setting and inflation continues to be moderate, there will be no need for a restrictive monetary policy. Thus the German economy will, due to slower demand from the US and higher costs of financing, lose momentum, but chances are good that the upswing will only take a break. In the coming year private consumption is expected to be the main contributor to growth, because wage incomes will expand strongly. Unemployment will continue to shrink, albeit at a smaller rate than during 2007. Fiscal policy will no longer be restrictive. Economic policy has improved the conditions for growth in Germany; there is, however, still much to do. Public finances have to be consolidated further, but at the same time, public investment has to be strengthened. This can be achieved if public consumptive expenditure growth is limited. The institutes suggest to increase public expenditure by 2% per annum over the cycle in nominal terms; this is, by less than by the trend growth rate of nominal GDP.
The institutes advise against a reversal of the recent labour market reforms. Instead, incentives for taking up jobs should be increased further.

The Role of Credit Ratings in Banking Regulations. Credit Ratings Are Insufficiently Anticipating the Risk for Currency Crises.
Tobias Knedlik, Johannes Ströbel
Wirtschaft im Wandel,
No. 10,
2007
Abstract
This contribution analyses whether the behaviour of rating agencies has changed since their failure to predict the Asian crisis. The paper finds no robust econometric evidence that rating agencies have started to take micro-mismatches into account when assigning sovereign ratings. Thus, given the current approach of credit rating agencies, we have reservations concerning the effectiveness of Basel II to prevent the transmission from currency crises to banking crises for potential future crises.

Market Follows Standards
Ulrich Blum
Wirtschaft im Wandel,
No. 10,
2007
Abstract
Standards are an important part of the codified knowledge of a society. In contrast to industry standards, formal standards are created in a consensus-based procedure open to all interested parties. Only if an economic interest for application exists will formal standards be produced. Interested parties have to shoulder participation costs themselves, which enforces economic interest. Up to a certain extent, governments also trigger and finance formal standardisation processes through the new approach, which creates a framework that is filled by private activity. Standards stand at the end of intellectual property rights if the totality of the value chain of knowledge production is looked at. One important aspect is their accessibility and the inclusion of all necessary intellectual property rights, especially patents, at reasonable prices. Conversely, consortia may exclude groups from the use of their standards. By preventing the licensing of those patents included in a standard, they can effectively block market entry. Thus, “successful” standards often face antitrust problems. Formal standards reduce costs of production through economies of scale, economies of scope and network-economies. Goods and processes that are standardized signal quality, the inclusion of high technological standards and permanent presence in the markets, which again accelerates market dissemination. Firms face a dilemma: On the one hand, the penetration of a markets with industry standards offers potentials for high profits; on the other hand, this has to be balanced against the risk of failure, especially if clients are hesitant because they do not know which standard will be successful in the end. Formal standards create and stabilize trust markets. This is especially true in the area of globalisation. Europe, which has to face an enormous competition in the international knowledge economy, needs an institutionally efficient approach to formal standardisation. This contribution addresses future problems of the European standardisation that have been developed within the framework of a working group of the European Standardisation Organisation called Future Landscape of European Standardisation (FLES).

Business Cycle Update Summer 2007: German Upswing Still Healthy
Wirtschaft im Wandel,
No. 8,
2007
Abstract
In the summer of 2007, the economies of the European Union and Japan continue their upswing, while the USA is still suffering from economic weakness. The expansion of the East Asian economies remains highly dynamic. Compared to the beginning of the year, conditions at the global financial markets have deteriorated slightly: Long-term interest rates have risen considerably; with notably more than half of a percentage point the increase was especially pronounced in the Euro Area. Furthermore, markets have become increasingly volatile. The less favourable conditions at the global financial markets, among other reasons, will cause the upswing in the Euro Area and Japan to slightly slow down. While the USA will not enter a phase of stagnation, the economy will continue to expand at rates below its potential until 2008. In Germany, the economic recovery took a temporary break in the first half of 2007. While special circumstances (first, brought forward purchases in anticipation of the increase in the value added tax and second, the high construction activity because of the end of home owners subsidies) raised considerably economic activity towards the end of 2006, they caused a downturn in demand in the beginning of 2007. After this short dip, the upswing will recommence. Private consumption will be the main driving force, as incomes have increased considerably in the wake of the improved labour markets conditions. The upswing will continue next year, albeit at a slower pace. Higher interest rates, the appreciation of the Euro and the expected rise in labour costs will have some impact. Overall domestic demand will slow down, but only a little, as household consumption increases. GDP will expand by 2.6% and 2.5% in this and next year, respectively. The number of unemployed persons will decline below 3.5 million in 2008.

Banking Regulation: Minimum Capital Requirements of Basel II Intensify Transmission from Currency Crises to Banking Crises
Tobias Knedlik, Johannes Ströbel
Wirtschaft im Wandel,
No. 8,
2007
Abstract
Emerging market currency crises are often followed by banking crises. One reason for the transmission is the increased value of foreign debt measured in local currency. Equity capital is often insufficient to ensure liquidity. This problem is addressed by Basel II, in particular by its minimum capital requirements. In difference to the current regulation (Basel I), Basel II employs a differentiated risk weighing on base of credit ratings. This contribution calculates the hypothetic effects of the new regulation on minimum capital requirements for the example of the South Korea currency and banking crises of 1997. The results are compared to current regulation. It can be shown that minimum capital requirements in the case of Basel II would have been lower than in the case of Basel I. Additionally, minimum capital requirements would have increased dramatically. The transmission from currency to banking crises would not have been prevented, but would have been accelerated. Thereby, minimum capital requirements under Basel I have been relatively low because of South Korea’s OECD membership. It can therefore be concluded that in other emerging market economies, which are not OECD members, the ratio of minimum capital requirements of Basel II to the minimum capital requirements of Basel I prior the crises would have been even lower. Therefore, the new instrument of banking regulation would have intensified the transmission from currency to banking crises.

Institutionelle Defizite und wachsende Spannungen in der Euro-Zone
Hubert Gabrisch
Wirtschaft im Wandel,
No. 7,
2007
Abstract
The introduction of the Euro was certainly a success. Nevertheless, behind this success one may find some increasing asymmetries and imbalances across member countries, which may undermine the stability of the common currency in the long run. Tensions include the paralysis of fiscal policy, increasing divergence in per capita income, a high volatility of real state prices, and diverging unit labour cost developments. The given forms of macroeconomic coordination seem not to be appropriate to mitigate the problems. Obviously, countries can compete with wage policy only after currencies and their exchange rates were abolished, and the use of fiscal policy has been restricted. In particular, Germany and Austria were successful in competitive wage policy, while countries like Spain, Greece, Portugal, Italy, and also France did not yet use the competitiveness channel. Germany was able to reduce its unit labour costs more than other countries by labour market reforms and higher indirect taxes in replacing social taxes. However, the advantage may proof to be temporary only, for other countries will be forced to follow the German example. Given an ECB inflation target of 2 %, more competitive wage policy in the Euro area might jeopardize the stability of the currency through deflation and higher unemployment. It does not wonder that the discussion on other and new forms of macroeconomic coordination revived recently. This debate does not only include the introduction of a central EU budget with anti-cyclical effects, but also forms of direct and indirect coordination of national wage policies. In any case, it would be useful to oblige national wage policies to obey the common interest of the Union.

Systematic Mispricing in European Equity Prices?
Marian Berneburg
IWH Discussion Papers,
No. 6,
2007
Abstract
One empirical argument that has been around for some time and that clearly contra- dicts equity market efficiency is that market prices seem too volatile to be optimal estimates of the present value of future discounted cash flows. Based on this, it is deduced that systematic pricing errors occur in equity markets which hence can not be efficient in the Effcient Market Hypothesis sense. The paper tries to show that this so-called excess volatility is to a large extend the result of the underlying assumptions, which are being employed to estimate the present value of cash flows. Using monthly data for three investment style indices from an integrated European Equity market, all usual assumptions are dropped. This is achieved by employing the Gordon Growth Model and using an estimation process for the dividend growth rate that was suggested by Barsky and De Long. In extension to Barsky and De Long, the discount rate is not assumed at some arbitrary level, but it is estimated from the data. In this manner, the empirical results do not rely on the prerequisites of sta- tionary dividends, constant dividend growth rates as well as non-variable discount rates. It is shown that indeed volatility declines considerably, but is not eliminated. Furthermore, it can be seen that the resulting discount factors for the three in- vestment style indices can not be considered equal, which, on a risk-adjusted basis, indicates performance differences in the investment strategies and hence stands in contradiction to an efficient market. Finally, the estimated discount rates under- went a plausibility check, by comparing their general movement to a market based interest rate. Besides the most recent data, the estimated discount rates match the movements of market interest rates fairly well.

Die Lage der Weltwirtschaft und der deutschen Wirtschaft im Frühjahr 2007
Wirtschaft im Wandel,
1. Sonderausgabe
2007
Abstract
In spring 2007, the global economy remains robust. While growth rates have declined slightly from last year, as business activity in the US has slowed, they continue to reflect an upswing, which by now has held on for a notably long time. Especially the developing and emerging countries have been raising output very fast, due in part to their increasing role in the international division of labour. In the industrialised economies, on the other hand, the current recovery has not been remarkably strong. So far the slowdown in the US economy has not spilled over to other regions and the Euro Area as well as Japan continue to expand at a high pace. Here expansive monetary policy provided a notable support. Buoyant financial markets stimulated the world economy additionally, even though market volatility has increased since the end of February. The US central bank’s current concern with inflationary risks keeps it from loosening its slightly restrictive monetary policy. It will be the second half of the year – when price pressures have eased – until the Fed makes its first rate cut. The ECB, on the other hand, has been preparing financial markets for a further increase in interest rates by summer. In 2007 and 2008 the growth disparities in the industrialised countries will diminish. On one hand, the upswing in the Euro Area will start to moderate, as fiscal policy hampers business activity and monetary policy will not stimulate anymore. On the other hand, the US economy will slowly gain pace from summer onwards; the emerging markets will continue to develop in a highly dynamic fashion. World-GDP in this and next year will likely rise by about 3 ¼ % in 2007, which is still faster than in the average of the last ten years. World trade will rise by 7 ½ % in the coming two years. An oil price of 65 US-Dollar and an exchange rate between the Euro and the US-Dollar of 1.32 were assumed for both years 2007 and 2008. The real estate market in the USA continues to be a risk for...
