Efficiency of qualification and job creating measures in East Germany
Wirtschaft im Wandel,
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.

The Effect of Expected Effective Corporate Tax Rates on Incremental Financing Decisions
IMF Staff Papers,
This paper uses U.S. panel data to estimate the effect of expected effective corporate tax rates on the amount of debt issued by firms. The paper directly estimates expected corporate tax rates using rational expectations. The estimated measures of expected effective tax rates of firms are related to a continuous measure of incremental debt financing. The paper finds that expected effective tax rates are significantly and positively related to a higher level of debt financing. Simulations suggest that debt issues would double if firms were unable to shield profits and actually faced the statutory tax rate.
