Evaluation von Maßnahmen der aktiven Arbeitsmarktpolitik mit Hilfe eines iterativen Matching-Algorithmus - Eine Fallstudie über langzeitarbeitslose Maßnahmeteilnehmer in Sachsen

IWH Discussion Papers,
No. 173,
2003
Abstract
The paper evaluates the effects of two labor market programs in Germany, namely the Job Creation- /Structural Adjustment Scheme and Vocational Training, on the unemployment duration of long term unemployed persons. The study uses data from the Mikrozensus Sachsen. A two step Nearest-Neighbor-Matching is employed to solve the sample selection problem. The first step is the estimation of the participation tendency to obtain potential pairs and to compute their Mahalanobis distances. For the assignment of pairs in the second step two different procedures are used: a standard technique and a new one - the iterative improvement of an initial assignment. This process is superior to the standard matching algorithms in the sense that it allows for a closer match between participants and non-participants. Including additional information about a person’s employment history enables us to eliminate the bias due to unobservables. The impact of participation in a labor market program is evaluated by comparing the unemployment duration between both groups using the Cox Proportional Hazard Model. Overall we find empirical evidence that both participation in Job Creation- /Structural Adjustment Scheme and Vocational Training result in even longer unemployment.

Effects of accelerated extension of the East German traffic infrastructure - The example of the A 72 Chemnitz-Leipzig

No. 12,

Abstract
Growth and the productivity can be positively affected by the accelerated development of the infrastructure by regions. That was empirically proven by a study of the IWH. The example of the planned motorway BAB 72 Chemnitz-Leipzig shows that a prema-ture realization of the entire route will have important impulses for investments, em-ployment and turnover of firms.

The flood disaster and GDP in Germany
Udo Ludwig, Hans-Ulrich Brautzsch
Wirtschaft im Wandel,
No. 12,
2002
Abstract
The flood at Elbe, Danube and their tributary streams destroyed billion Euros worth of Capital Stock. GDP, though, does not include Capital Stock, but production. On the basis of plausible assumptions the production interruptions caused by the flood are estimated for Germany and the most severely affected areas of Saxony and Saxony-Anhalt. Considering the “set-aside” funds for restoration and with the help of the Input-Output-Model the direct effects on production and employment within the different economic sectors are being calculated. The results are compared with the foregone consumption due to the delayed next step of the tax reform. On balance clear effects can be observed in construction.

Municipal labor market policy - Marshalling yard or escape from public assistance dependency?
Hilmar Schneider
Wirtschaft im Wandel,
No. 11,
2001
Abstract
Due to an increasing fiscal burden by welfare payments, municipalities tend
more and more to initiate employment and training programs under their own
responsibility besides the Federal Labor Agency. However, critics object
that this might predominantly be viewed as an attempt to shift fiscal
burdens to the Federal Labor Agency rather than a policy option towards
labor market integration of low-wage workers. In order to investigate this
issue, the IWH carried out a country-wide survey within twelve
municipalities and rural districts. The sample comprises 200 employable
welfare recipients, among them participants of labor market programs as well
as a reference group of non-participants. The results of the IWH welfare
survey are at best suggesting a moderate success of program participation
with regard to labor market integration. Nevertheless, the programs appear
to be profitable for municipalities, since they succeed in bringing
participants out of welfare dependency. In many cases, however, welfare is
replaced by unemployment support, which means that only the fiscal
responsibility changes. A shortcoming of the results has to be seen in the
fact that municipalities tend to assign especially those people for program
participation, who are already better fitting into requirements of the labor
market. This seriously impairs the comparability of participants and
non-participants. In view of the remarkable amount of expenditures it seems
therefore advisable to put more attention on the effectiveness of the
programs than has been done in the past. This could be achieved by a
stronger orientation towards an experimental design of assignment for
program participation.

Methodical limits of calculating productivity in the new Länder
Gerald Müller
IWH Discussion Papers,
No. 129,
2000
Abstract
The „Arbeitskreis Volkswirtschaftliche Gesamtrechnung der Länder“ now publishes figures concerning the value added in Germany. Formerly the Statistische Bundesamt had this assignment. Some corporations have plant locations in the new Länder as well as in the old Länder. The employed method for splitting-up the value added produce by these corporations might lead to an underestimation of the overall value added produced in the new Länder. However, an estimation using the firm panel of the IAB shows that the East German productivity gap for manufacturing is overestimated by maximally two percentage points. Still in sectors that are dominated by multi plant corporations this effect is stronger. All in all the East German productivity gab is overestimated by maximally three percentage points.

Moderate production and employment effects through rising crude oil prices – A simulation with the macroeconomic IWH model –
Christian Dreger
Wirtschaft im Wandel,
No. 15,
2000
Abstract
In the article the impacts of a rise in oil prices on production and employment are examined. The impacts are carried out by simulation on the grounds of a macroeconometric model. Given various price developments, the effects on production and employment are less pronounced than those in previous crisis. In the worst case scenario, output losses are 0.4 percentage points of the overall growth rate of the economy.

Efficiency of qualification and job creating measures in East Germany
Annette Bergemann, Birgit Schultz
Wirtschaft im Wandel,
No. 9,
2000
Abstract
This paper evaluates job creation schemes and further training in East Germany for the period 1990-1998. We identify the causal effect of the treatment-on-the-treated by a two-step procedure: First, we apply the matching technique based on estimated propensity scores. Secondly, we use the Difference-in-Differences estimator. Hereby, we take especially consideration on Ashenfelter s Dip, which characterize a significant decrease in the participants employment shortly before the start of a program. This can be assumed to be related to the anticipation of the participation.

Reduction of transfer payments to East Germany: Contractive effects only in the short term
Joachim Ragnitz, Christian Dreger
Wirtschaft im Wandel,
No. 7,
2000
Abstract
By applying a macroeconometric model, the effects of a substantial reduction of transfers for the New Laender are studied. It is argued that in the short run convergence will be hampered severely if transfers are reduced abruptly; however, in the long the negative effects on the East German economy can be ignored.

The Total Cost of Trading Belgian Shares: Brussels versus London
Hans Degryse
Journal of Banking and Finance,
No. 9,
1999
Abstract
Since 1990, London’s SEAQ International (SEAQ-I) has attracted considerable trading volume in Belgian equities. This paper investigates competition between the Brussels CATS market and London’s SEAQ-I. Toward this end, we gathered extensive limit order book data as well as transactions and quotation information. With regard to liquidity (indirect costs), measured by the quoted and effective bid–ask spread, the paper concludes that CATS outperforms SEAQ International for both measures. The effective spread is of course substantially smaller than the quoted spread, with the CATS effective spread showing a U-shaped form. This paper, unique in employing an extensive data set that includes all hidden orders and the whole limit order book, produces results in line with the different market microstructure models. Total trading costs on CATS are lower (higher) for small (large) trade sizes.
