Instrumental variable estimation requires untestable exclusion restrictions. With policy effects on individual outcomes, there is typically a time interval between the moment the agent realizes that he may be exposed to the policy and the actual exposure or the announcement of the actual...

In this paper we study doubly robust estimators of various average treatment effects under unconfoundedness. We unify and extend much of the recent literature by providing a very general identification result which covers binary and multi-valued treatments; unnormalized and normalized weighting;...

We study semiparametric two-step estimators which have the same structure as parametric doubly robust estimators in their second step, but retain a fully nonparametric specification in the first step. Such estimators exist in many economic applications, including a wide range of missing data and...

This paper analyzes the patent propensity as an outcome of innovative activities of regional SMEs. To achieve the aims, we apply robust regression analysis to estimate the models to test 5 research hypotheses using 263 firm level data located at Gwangju region in Korea. Our empirical results...

In many countries, caseworkers in a public employment office have the dual roles ofcounselling and monitoring unemployed persons. These roles often conflict with each otherleading to important caseworker heterogeneity: Some consider providing services to theirclients and satisfying their demands...

This paper extends the widely used ordered choice model by introducing stochasticthresholds and interval-specific outcomes...

In an evaluation of a job-training program, the influence of the program on the individualearnings capacity is important, because it reflects the program effect on human capital.Estimating these effects is complicated because earnings are observed for employedindividuals only, and employment is...

India is a country characterized by a huge informal sector. At the same time, it is a country where the extent of corruption in every sector is remarkably high. Stifling bureaucratic interference and corruption at every stage of economic activities is one of the main reasons behind high...

In this paper, we use a recent policy change in the Netherlands to study how changes in search requirements for the older unemployed affect their transition rates to employment, early retirement and sickness/disability benefits. The reform, becoming effective on January 1st 2004, required the...

Leaders are critical to a country's success. They can influence domestic policy via specific measures that they enforce, and they can also influence international public opinion towards their country. Foreign Direct Investments are also essential for a country's economic growth. Our hypothesis...
