This paper uses newly available data for German business services firms to test a hypothesis derived by Bustos (AER 2011) in a model that explains the decision of heterogeneous firms to export and to engage in R&D. Using a non-parametric test for first order stochastic dominance it is shown...

This paper presents the first empirical test with German firm level data of a hypothesis derived by Bustos (AER 2011) in a model that explains the decision of heterogeneous firms to export and to engage in R&D. Using a non-parametric test for first order stochastic dominance it is shown that, in...

Recent empirical studies suggest a need for a flexible patent regime responding to industry characteristics. In practice, sector-specific modifications of patent strength already exist but lack theoretical foundation. This paper intends to make up for this neglect by scrutinizing in what...

This paper develops an oligopolistic model of international trade with heterogeneous firms and endogenous R&D to examine how trade liberalization affects firm and industry productivity, as well as social welfare. We identify four effects of trade liberalization on productivity: (i) a direct...

The paper focuses on the impact of business related R&D spending on input factor productivity (IFP) using international patent applications as a technology diffusion channel. Considering the relationship between research and productivity, international patent pattern reflects the link between...

Our paper decomposes knowledge-diffusing trade flows and estimates their impacts separately. Overall, trade generates positive knowledge spillovers, but the effects of intra-industry trade are ambiguous. With regard to sectoral import penetration, we find that potential positive spillovers are...

This article examines to what extent recent empirical evidence can collectively and systematically substantiate the claim that entrepreneurship has important economic value. Hence, a systematic review is provided that answers the question: What is the contribution of entrepreneurs to the economy...

Many writers have claimed that R&D has two 'faces'. In addition to the conventional role of stimulating innovation, R&D enhances technology transfer by improving the ability of firms to learn about advances in the leading edge ('absorptive capacity'). In this paper we document that there has...

The modern manufacturing firm competes with product quality improvements rather than cost efficient production of simpler products. R&D spending, marketing, availability of spare parts and service facilities, customs designs, etc. embody the product quality enhancing process, requiring...

Radical innovations require risk-taking. However, it is hard to find an objective measure for innovation investments that would take riskiness into account. In this paper, we investigate how a simple measure of firms’ innovation investments, namely the employee share of managers and...
