Measurement error in historical data distorts descriptive analyses based on binary classifications. Modern replications of deficiencies in retrospective CPI estimates for the 19th century show that measurement issues cause misclassification of inflationary and deflationary episodes. We therefore...

This paper models the long-run relationship between the Bureau De Change exchange rate and external reserves in Nigeria in a Threshold Vector Error Correction Model (TVECM) framework using daily data that spans from Jan 1, 2014 to Jul 31, 2015. Modeling BDC exchange rate and external reserves...

The paper proposes two estimation approaches for duration models that are subject to right censored observations and selection effects. Main focus is on accelerated duration models and the estimators that are of the limited information type, i.e. they are not based on a fully specified selection...

The IAB employment subsample is now available for researchers in a third, anonymised version. Following the so-called basic file and the regional file from the IAB employment subsample, which encompassed the years 1975 to 1990, the actualized version of the basic file covers now the years 1975...

This paper reviews approaches used for evaluating the performance of local or regional innovation systems. This evaluation is performed by a benchmarking approach in which a frontier production function can be determined, based on a knowledge production function relating innovation inputs and...

In this paper it is shown that it matters a lot for empirical research whether policy is taken to be exogenously set or to be endogenous. In the model investment depends on policy which depends on economically important fundamentals and is, thus, endogenous. Conditioning on factor accumu- lation...

In dieser Arbeit wird ein Überblick über einige Kernaussagen der ''Neuen Wachstumstheorie'' über den Zusammenhang von Wissen und wirtschaftlicher Entwicklung gegeben. Ausgehend von der ''neoklassischen'' Wachstumstheorie wird die Bedeutung von Wissen in Prototypen endogenen Wachstums der...

This papers describes an estimator for a standard state-space model with coefficients generated by a random walk that is statistically superior to the Kalman filter as applied to this particular class of models. Two closely related estimators for the variances are introduced: A maximum...

The diffusion of Temporary Work Agency (TWA) jobs originated a harsh policy debate and ambiguous empirical evidence. Results for the US, based on quasi-experimental evidence, suggest that a TWA assignment decreases the probability of finding a stable job, while results for Europe, based on the...

Instrumental variables estimates of the effect of military service on subsequent civilian earnings either omit schooling or treat it as exogenous. In a more general setting that also allows for the treatment of schooling as endogenous, we estimate the veteran effect for men who were born between...
