Higher productivity in importing German manufacturing firms: self-selection, learning from importing, or both?

This paper uses a newly available comprehensive panel data set for manufacturing enterprises from 2001 to 2005 to document the first empirical results on the relationship between imports and productivity for Germany, a leading actor on the world market for goods. Furthermore, for the first time the direction of causality in this relationship is investigated systematically by testing for self-selection of more productive firms into importing, and for productivity-enhancing effects of imports ('learning-by-importing'). We find a positive link between importing and productivity. From an empirical model with fixed enterprise effects that controls for firm size, industry, and unobservable firm heterogeneity we see that the premia for trading internationally are about the same in West and East Germany. Compared to firms that do not trade at all two-way traders do have the highest premia, followed by firms that only export, while firms that only import have the smallest estimated premia. We find evidence for a positive impact of productivity on importing, pointing to self-selection of more productive enterprises into imports, but no clear evidence for the effect of importing on productivity due to learning-by-importing

Bidirectional Needs Assessment of Otolaryngology-Head and Neck Surgery Short-term Surgical Trips in Zimbabwe

OBJECTIVES: To describe findings from an otolaryngology-specific needs assessment tool in Zimbabwe. METHODS: Surveys were developed and shared with Low-Middle Income Country (LMIC) hosting institutions in Zimbabwe and to High-Income Country surgical trip participants (HIC). Respondents were otolaryngologists identified online and through professional networks who had participated in a surgical trip. RESULTS: The most common procedures Zimbabwe otolaryngologists reported treating were adenotonsillectomy (85.7%), chronic rhinosinusitis (71.4%), chronic otitis (57.1%), and head and neck tumor intervention (57.1%). The most common untreatable conditions that host physicians wanted to treat were skull base surgery (71.4%), flap reconstructions (57.1%), and laryngotracheal reconstruction (57.1%). The largest discrepancy between host desires and visiting team offerings were flap reconstruction (57.1%), nasal bone deformities (37.1%), and laryngotracheal reconstruction (17.1%). Perceptions of short-term surgical trips (STST) were recorded for host and visiting teams, and important differences between the public and private sectors of care in Zimbabwe were also identified. CONCLUSION: The surveys utilized in this study served as a bidirectional needs assessment of the requirements and care goals of host institutions and visiting teams in Zimbabwe. Differences between public and private sectors of care, particularly regarding infrastructure, resources, and surgical goals, were revealed, and the results can be utilized as part of efforts to maximize efforts within global surgical partnerships.

Trade openness, real exchange rates and job reallocation

This paper investigates the impact of real exchange rate movements on job reallocation at the industry level. The analysis focuses on the manufacturing sector of Belgium, using data for 82 NACE 3-digit industries, over the time span 1996-2002. I find that real exchange rate changes do have a significant impact on job flows, and that this impact is magnified by increasing levels of trade exposure. In particular, a real appreciation is found to lower net employment growth through higher job destruction, while job creation is not significantly affected. These results are in line with previous empirical evidence on the United States, and differ from earlier findings for France and Germany, where the adjustment to real exchange rate shocks has been found to occur mainly through the job creation margin. I suggest that these differences may be explained by the fact that Belgium is a small open economy
