Abstract
This article investigates women’s and men’s labor supply to the firm within a semistructural approach based on a dynamic model of new monopsony. Using methods of survival analysis and a large linked employer‐employee data set for Germany, we find that labor supply elasticities are small (1.9–3.7) and that women’s labor supply to the firm is less elastic than men’s (which is the reverse of gender differences in labor supply usually found at the level of the market). Our results imply that at least one‐third of the gender pay gap might be wage discrimination by profit‐maximizing monopsonistic employers.

Human Capital and Fertility in Germany after 1990: Evidence from a Multi-Spell Model
Marco Sunder
IWH Discussion Papers,
No. 22,
2009
Abstract
We analyze the timing of birth of the first three children based on German panel
data (GSOEP) within a hazard rate framework. A random effects estimator is
used to accommodate correlation across spells. We consider the role of human
capital – approximated by a Mincer-type regression – and its gender-specific
effects on postponement of parenthood and possible recuperation at higherorder
births. An advantage of the use of panel data in this context consists in
its prospective nature, so that determinants of fertility can be measured when
at risk rather than ex-post, thus helping to reduce the risk of reverse causality.
The analysis finds evidence for strong recuperation effects, i.e., women with
greater human capital endowments follow, on average, a different birth history
trajectory, but with negligible curtailment of completed fertility.

Firm Density in East Germany: Findings from the Business Register

Wirtschaft im Wandel,
No. 10,
2008
Abstract
The contribution focuses on the business density in East Germany in comparison with West Germany. For the purpose of the investigation, a new information source was used – the so-called Business Register. Business density in East Germany is of relevance for two reasons: First, when the wall came down in 1989, the East German economy suffered from the lack of private firms. Second, after 2000, a gap in terms of work places is still existent. The empirical data on business density in East Germany do not reveal an unequivocal picture. Measuring business density by comparing the number of firms with the respective number of population reveals a gap in terms of the number of businesses per 10 000 inhabitants in East Germany. The gap is above average with respect to firms in the manufacturing sector, and it is particularly high regarding larger manufacturing firms. Measuring the business density as a quota of the number of firms and the volume of Gross Domestic Product (GDP) reveals a reverse picture: The business density in relation to GDP is on average higher in comparison with the respective value in West Germany. Maybe, the size of the East German market sets limits regarding the number of firms which may act there. However, the size of the domestic market is not so relevant for the firms belonging to the manufacturing sector and to the business-related services since they are expanding to a large extent due to their export activities. Though from the manufacturing sector, relativly positive development perspectives can be expected, the number of large firms per 10 000 inhabitants is relatively low in comparison with West Germany. Public support for strengthening the business landscape in the East German manufacturing sector remains on the agenda of economic policy in Germany.

Comparing the training activities of unemployed and full-time employed people
Birgit Schultz, Joachim Wilde
Zeitschrift für Arbeitsmarktforschung,
No. 1,
2008
Abstract
Many empirical studies for Germany consider either the training activities of the unemployed or those of employees. However, a comprehensive comparison of both groups had not been conducted until now. The paper closes this gap. Using data from the latest time-use survey (Zeitbudgeterhebung) of the Federal Statistical Office, the amount of training undertaken by the two groups is compared. Furthermore, the types of activities that are made use of in particular are described. Heterogeneity due to different relevant socioeconomic characteristics in the two groups is eliminated by applying a matching procedure. The findings demonstrate that only 49% of unemployed people participate in any kind of training activity off the job. In the case of full-time employment 59 % would take part. Concerning the average expenditure of time per week the difference is reversed, i.e. the expenditure of time is greater during unemployment. However, a large proportion of the training activities undertaken by the unemployed comprises general training, e.g. by reading books or watching television. Furthermore, the result is driven by a different potential of time that can be used for training activities off the job. In relation to this potential of time, the amount of training activity is still smaller during unemployment.

Forecasting the CO2 certificate price risk
Henry Dannenberg, Wilfried Ehrenfeld
IWH Discussion Papers,
No. 5,
2008
Abstract
Modeling the price risk of CO2 certificates is one important aspect of integral corporate risk management related to emissions trading. The paper presents a risk model which may be the basis for evaluating the risk of emission certificate prices. We assume that the certificate price is determined by the expected marginal CO2 abatement costs prevailing at the current trade period and stochastically fluctuates around the respective level as returned from the mean reversion process. Due to uncertainties about future environmental states we suppose that within one trade period, erratic changes in the expected marginal abatement costs may occur leading to shifts in the price level. The aim of the work is to model the erratic changes of the expected reversion level and to estimate the parameters of the mean reversion process.

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.

Aggressive Orders and the Resiliency of a Limit Order Market
Hans Degryse, Frank de Jong, Maarten Van Ravenswaaij, Gunther Wuyts
Review of Finance,
No. 2,
2005
Abstract
We analyze the resiliency of a pure limit order market by investigating the limit order book (bid and ask prices, spreads, depth and duration), order flow and transaction prices in a window of best limit updates and transactions around aggressive orders (orders that move prices). We find strong persistence in the submission of aggressive orders. Aggressive orders take place when spreads and depths are relatively low, and they induce bid and ask prices to be persistently different after the shock. Depth and spread remain also higher than just before the order, but do return to their initial level within 20 best limit updates after the shock. Relative to the sample average, depths stay around their mean before and after aggressive orders, whereas spreads return to their mean after about twenty best limit updates. The initial price impact of the aggressive order is partly reversed in the subsequent transactions. However, the aggressive order produces a long-term effect as prices show a tendency to return slowly to the price of the aggressive order.

Prospects for 2002: Waiting for the cyclical change
Wirtschaft im Wandel,
No. 1,
2002
Abstract
This article updates the complete analysis and forecast of the economic developments in the World and Germany in particular for 2002, as published in Summer. After six quarters of downturn, the beginning of 2002 does not show signs of a revival in economic activity. Neither internal nor external forces are currently strong enough to reverse the underlying downward trend. It is assumed that by spring time the recession in the USA will have faded. Resulting is a stimulus for the World Economy. This initiating impulse will revive production in Germany and the Euro Area, which by the second half of 2002 will gain pace. The increase in exports, as induced by the upturn in the US-Economy will positively affect domestic demand. With the usual time lag this development will also strengthen the job market. Monetary Policy will remain expansive and begins to show its full effect. Fiscal Policy, on the other hand, due to the need for consolidation, will remain restrictive.

Public Research Institutions in East Germany: a Promising Base for Economic Upturn?
Gerhard Heimpold, Martin T. W. Rosenfeld
Wirtschaft im Wandel,
No. 15,
2001
Abstract
In the 1990s a lot was done to strengthen public research efforts in East Germany. The main indicators relating to public research reflect an ambivalent picture. Investment by universities and public research institutions outside the universities reached a higher level than in West Germany. However, there remains an East-West gap with respect to the capital stock. The per capita stock of R&D staff in the university sector reached almost the level in the old Länder. With respect to the university R&D in engineering sciences, among those fields of university research which are particularly business-related, per capita stock of staff as well as per capita investment in the Eastern German Länder are above the West German level. In university natural science the East-West pattern of the R&D input factors mentioned is reversed. The receipts of the universities acquired from research contracts, which may be used as an indicator to assess the quality of public research, reveal shortcomings. These shortcomings, though these have been partly caused by the transitional situation in East Germany`s universities, where new institutions were built up only gradually. The R&D institutions outside the universities are obviously better equipped than such institutions in West Germany.
The visible advantages offered by public sector research institutions in East Germany might be used much more intensively to foster the economic reconstruction in East Germany. In parallel with this, the remaining shortcomings of public R&D in East Germany should be eliminated. If reductions in universities´ capacities (due, for instance, to a declining number of persons who have a university entrance qualification) seem to be inevitable, the consequences of such restrictions should be carefully reconsidered.
