We hypothesize that North-South trade is associated with knowledge spillovers that create labor productivity gains depending on various determinants of Southern absorptive capacity. We use the novel World Input-Output Database (WIOD) that provides bilateral and bisectoral panel data for 39...

Firms invest huge amounts into intangible assets. This paper explores to which extent different kinds of intangible assets are conducive to firm-level productivity. Our study contributes to the literature by simultaneously comparing productivity effects of innovative capital, human capital,...

Motivated by Manski and Tamer (2002) and especially their partial identification analysis of the regression model where one covariate is only interval-measured, we offer several contributions. Manski and Tamer (2002) propose two estimation approaches in this context, focusing on general results....

We investigate how competition in product niches affects the ultimate timing of product release for experience goods using data on motion pictures in the United States. We identify product niches that movies occupy along three different product dimensions: common actor, common director, and...

Peer influence through word-of-mouth (WOM) plays an important role in many information systems but identification of causal effects is challenging. We identify causal WOM effects in the empirical setting of game adoption in a social network for gamers by exploiting differences in individuals'...

The Bologna Process was introduced in the member states of the European Union in 1999 with the aim of creating a European Higher Education Area. The main component of the reform was the replacement of the existing national systems of higher education degrees with a homogeneous Bachelor-Master...

This paper analyses the impact of business process outsourcing (BPO) on firm productivity based on a comprehensive German firm-level panel data set covering manufacturing and service industries. The growing importance of service inputs into the production process is undisputed. Firms...

This paper shows that earnings losses after unemployment increase with age. First, older employees start out with relatively high earnings in comparison to employees without employment interruptions several years before the non-employment spell. This earnings advantage turns into a strong...

The fixed effects (FE) panel model is one of the main econometric tools in empirical economic research. A major practical limitation is that the parameters on time-constant covariates are not identifiable. This paper presents a new approach to grouping FE in the linear panel model to reduce...

We discuss important properties and pitfalls of panel-data event study designs. We derive three main results. First, binning of effect window endpoints is a practical necessity and key for identification of dynamic treatment effects. Second, event study designs with binned endpoints and...
