We propose an Instrumental Variable method for Generalised Accelerated Failure Time (GAFT) models that adjust for possible endogeneity of the intervention of interest, without suffering the problems of the intention-to-treat method. We develop an estimatiom procedure that collapses to the linear...

We investigate why we observe non-negative duration dependence among young unemployed men in urban Ethiopia. Assuming that genuine duration dependence is negative, there are five explanations for a non-decreasing hazard: the presence of unemployment benefits, the existence of Active Labour...

Extended unemployment benefits programs in the US are triggered by the state insured unemployment rate while intrastate demand conditions often vary dramatically. Some tight local labor markets may therefore exhibit a large adverse effect of extended unemployment benefits. Using a competing risk...

Based on administrative data from the federal employment office in Germany, we apply matching techniques to estimate the stepping-stone function of temporary agency work for the unemployed, i.e. its short-run and long-run effects on their future employment prospects. Our results show that...

The system of Unemployment Insurance (UI) financing in the US draws its funds from a payroll tax on employers and varies the tax rate according to the individual employer's layoff history. There exists extensive evidence on the effect of this so-called experience rated tax on layoff decisions....

We estimate a semiparametric single-risk discrete-time duration model to assess the effect of vocational training on the duration of unemployment spells. The data basis used in this study is the German Socio-Economic- Panel (GSOEP) for West Germany for the period from 1986 to 1994. To take into...

We present evidence on the duration of firm-bank relationships using a unique panel data set of connections between Oslo Stock Exchange-listed firms and their banks for the period 1979-1994. We focus on the determinants of the duration of a relationship and the causes for ending an existing bank...

This paper studies the relationship between NSF funding and the publications of US economists using data on 1473 applications to NSF during 1985-1990, 414 of which were awarded a research grant. We first outline a basic methodology for assessing the impact of the NSF support for basic research...

The diffusion of health care technology is influenced by both the total market share of managed care organizations as well as the level of competition among them. This paper differentiates between HMO penetration and competition and examines their relationship to the adoption of cardiac...

This paper investigates the time between transactions on financial markets. It is assumed that the interval between transactions is a random variable and the relationship between the probability to observe a transaction at each instant of time and the type of the previous trade is investigated....
