Conventional wisdom in economic history suggests that conflict between countries can be enormously disruptive of economic activity, especially international trade. Yet nothing is known empirically about these effects in large samples. We study the effects of war on bilateral trade for almost all...

While innovation is argued to create value, private incentives of firms to innovate are driven by what part of the value created firms can appropriate. In this paper we explore the relation between innovation and the markups a firm is able to extract after innovating. We estimate firm-specific...

We disentangle the contribution of unobserved heterogeneity in idiosyncratic demand and productivity to firm growth. We use a model of monopolistic competition with Cobb-Douglas production and a dataset of Italian manufacturing firms containing unique information on firm-level prices to reach...

In the large literature on firm performance, economists have given little attention to entrepreneurs. We use deaths of more than 500 entrepreneurs as a source of exogenous variation, and ask whether this variation can explain shifts in firm performance. Using longitudinal data, we find large and...

This paper estimates the effects of the 1991 breakups of Czechoslovak state-owned enterprises (SOEs) on subsequent performance of the master enterprises and the spin-off units. The analysis is based on quarterly and annual data of Czechoslovak industrial enterprises. We estimate the performance...

Using two matched plant level skills and productivity datasets for UK manufacturing we document that (i) more productive firms hire more skilled workers: in 2000, plants at the top decile of the TFP distribution (controlling for their four-digit industry) hired workers with, on average, around...

This paper analyzes the effect of having a large gap in firing costs between permanent and temporary workers in a dual labour market on TFP development at the firm level. We propose a simple model showing that, under plausible conditions, both temporary workers' effort and firms' temp-to-perm...

Using the Spanish micro data from the Programme for the International Assessment of Adult Competencies (PIAAC), we first document how the excessive gap in employment protection between indefinite and temporary workers leads to large differentials in on-the-job training (OTJ) against the latter....

We study the relation between workers' skill dispersion and firm productivity using a unique dataset of Italian manufacturing firms from the early eighties to the late nineties with individual records on all their workers. Our measure of skill is the individual worker's effect obtained as a...

This paper evaluates the impact of the widespread use of fixed-term contracts in Spain on firms' TFP, via its effect on workers' effort. We propose a simple analytical framework showing that, under plausible conditions, workers' effort depends positively on their perception (for given level of...
