Firms with a reputation as socially responsible may have an important cost advantage: If workers prefer their employer to be socially responsible, equilibrium wages may be lower in such firms. We explore this hypothesis, combining Norwegian register data with data on firm reputation collected by...

Consider a setting where a treatment that starts at some point during a spell (e.g. in unemployment) may impact on the hazard rate of the spell duration, and where the impact may be heterogeneous across subjects. We provide Monte Carlo evidence on the feasibility of estimating the distribution...

An extended single-index model is considered when responses are missing at random. A three-step estimation procedure is developed to define an estimator for the single index parameter vector by a joint estimating equation. The proposed estimator is shown to be asymptotically normal. An iterative...

As cities play important roles in economic growth, the competitive power of foreign trade of cities has gained more and more attentions. Exporting hazard rate, as one dimension of foreign competitive power, shall be specifically measured. And its spatial distribution across cities shall be...

The paper proposes a model to investigate the influences of agglomeration on heterogeneous firms' exporting behaviors. In the model, firms are heterogeneous in productivity. Selection effect and agglomeration economies caused by agglomeration increase firms' productivity and decreases industrial...
