Abstract. Meta-regression analysis (MRA) can provide objective and comprehensive summaries of economics research. Their use has grown rapidly over the last few decades. To improve transparency and to raise the quality of MRA, the meta-analysis of economics research-network (MAER-Net) has created the below reporting guidelines. Future meta-analyses in economics will be expected to follow these guidelines or give valid reasons why a meta-analysis must deviate from them.

Abstract:Melitz's dynamic model of export participation is the basis of our empirical specification that accounts for a wide range of internal and external factors affecting the export behaviour of SMEs in Transition Countries (TCs). Using firm-level data, our estimates highlight the particular importance of the human and technology-related factors to the export behaviour of SMEs in TCs. Other important factors for SME exporting activities are productivity-enhancing spillovers from industry -especially vertical -linkages, firm size, ownership type, type of activity, the availability of external finance, networking through business associations, and market share. In addition, significant period and country differences are identified. This paper contributes to the transition literature by filling an important gap in the understanding of the SME internationalisation process and by identifying a comprehensive set of variables to explain firms' export behaviour in TCs.

Drawing on a sample of small and medium-sized enterprises (SMEs) in traditional manufacturing industries from seven EU regions, this study investigates how cooperation with external organisations affects technological (product and process) innovations and non-technological (organisational and marketing) innovations as well as the commercial success of product and process innovations (i.e., innovative sales). Our empirical strategy takes into account that all four types of innovation are potentially complementary. Empirical results suggest that cooperation increases firms’ innovativeness and yields substantial commercial benefits. In particular, increasing the number of cooperation partnerships has a positive impact on all measures of innovation performance. We conclude that a portfolio approach to cooperation enhances innovation performance and that innovation support programs should be demand-led.
