The classical Heckman (1976, 1979) selection correction estimator (heckit) is misspecified and inconsistent if an interaction of the outcome variable and an explanatory variable matters for selection. To address this specification problem, a full information maximum likelihood estimator and a...

This paper uses several macroeconomic and financial indicators within a Markov Switching (MS) framework to predict the turning points of the business cycle. The presented model is applied to monthly German real-time data covering the recession and the recovery after the financial crisis. We show...

The overestimation of willingness-to-pay (WTP) in hypothetical responses is a well-known finding in the literature. Various techniques have been proposed to remove or, at least, reduce this bias. Using about 30,000 responses on WTP for a variety of power mixes from a panel of 6,500 German...

Stylized facts show that migrants more often face overqualified employment than natives. As shown by previous research, one third of the employed foreign born with tertiary education in the EU-15 are overqualified, with levels reaching up to 57.6%, compared to 20.9% among natives. Among the...

In a competitive market situation, a symmetric price transmission is expected, and the speed of adjustment of the market should be equal, no matter in which direction input prices are going (up or down). When inputs' prices increase, firms need to pass on costs to avoid negative profit...

In federal countries, such as the U.S., the fiscal authority consists not of one, but many governments, with state governments accounting for a sizable share of expenditures. We analyze how state partisanship of politicians affects state fiscal policy and quantify the possible macroeconomic...

This paper develops a sample selection model for fractional response variables, i.e., variables taking values between zero and one. It is shown that the proposed model is consistent with the nature of the fractional response variable, i.e., it generates predictions between zero and one. A...

We identify the causal effect of lump-sum severance payments on non-employment duration in Norway by exploiting a discontinuity in eligibility at age 50. We find that a severance payment worth 1.2 months' earnings at the median lowers the fraction re-employed after a year by six percentage...

We introduce a dynamic treatment to the mixed proportional hazard competing risks model and allow for selection on unobservables. Our model can e.g. be used to evaluate the effect of benefit sanctions on the transition rate out of unemployment when more than one exit risk is of interest....

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...
