This paper studies the origins of Ricardian comparative advantage. I develop an endogenous growth model where productivity differences across firms and countries emerge from R&D investment by incumbent firms with heterogeneous R&D capabilities. Less productive firms have an advantage of backwardness and spillovers depend upon the productivity frontier in each country. The theory characterizes h...

Even though many employers believe that health insurance and health affect employees' productivity and firms' performance, health economists typically overlook and rarely measure firms' returns on health-related investments. Some research, however, suggests that firms may benefit economically by providing health insurance coverage for workers and their families. For example, health coverage may...

This paper examines how trade liberalization affects the innovation incentives of firms, and what this implies for industry productivity and social welfare. For this purpose we develop a reciprocal dumping model of international trade with heterogeneous firms and endogenous R&D. We identify two effects of trade liberalization on productivity: a direct effect through changes in R&D investment, a...

The causality from outsourcing, defined as the procurement of inputs from outside the boundaries of the firm, to productivity is tested for a large panel of Irish manufacturing firms. Theory suggests that as firms outsource more ‘non-core’ activities to specialized providers, productivity due to the firm benefiting from cheaper or higher-quality inputs and from reallocation of resources towards...

Input-output relationship, marginal productivity and marginal rate of technical substitution provide a useful insight about the potentiality of manufacturing firms. This study analyzes these important issues to describe the optimality in resource utilization of the manufacturing firms in the south-west region of Bangladesh. A translog production function has been estimated to describe the input...

This paper analyzes the impact of the decision to contract ICT consulting on firms’ innovative incentives. The paper develops a theoretical model and estimates some of its implications for a sample of German firms. In particular, the paper estimates the average treatment effect of the decision to contract ICT consulting on firms’ innovative incentives, considering the role of endogeneity and un...

While many theories about the relationship between information technology (IT) and organizational design have been proposed, there is little empirical evidence on the issue. We examine the influence of organizational design on the demand for IT and the productivity of IT investments, using data from approximately 380 US firms. We find greater demand for IT in firms with greater decentralization...

This paper empirically studies the impact of the adoption of open source software (OSS) on firms’ labor productivity and innovative behavior. Using a representative sample of German firms, the results show that the adoption of OSS operating systems for servers and general OSS applications has no impact on firm level labor productivity, while the adoption of OSS operating systems for PCs impacts...

WTO Accession and Performance of Chinese Manufacturing Firms* China’s policy-makers argued that WTO accession and the accompanying trade liberalization would have a beneficial impact on the domestic economy. China’s import tariffs differed tremendously across industry in the earlier years, but converged to an almost uniform low level after WTO entry. We exploit sectoral variation in the extent ...

In this paper, we construct a simple model based on heterogeneity in workers’ productivity and homogeneity in their working schedules. This simple model can generate unemployment, even if wages adjust instantaneously, firms are perfectly competitive, and firms can perfectly observe workers’ productivity and effort. In our model, it is optimal for low-skilled workers to be unemployed because, on...
