Using a large, longitudinal panel of US start-ups collected between 2004 and 2011, this article shows the extent to which intellectual property (IP) types, for example trademarks, patents, copyrights and outward licensing, enhance multidimensional performance. An ordered probit analysis corrected for sample selection bias, estimates performance to derive the following conclusions. First, trademarks and out-licensing IP types increase a firm’s chances of being a high performer, confirming the importance of certain forms of IP protection for start-ups. Second, patenting significantly reduces the chances of being a high performer, suggesting patenting has limited performance benefits for start-ups. Third, few performance synergies exist in the joint use of IP types, suggesting that strong complementarities among IP types are limited. While out-licensing patents and out-licensing copyrights increase performance, out-licensing patents and out-licensing trademarks diminish it. Furthermore, registering more trademarks and out-licensing more trademarks also diminishes performance, suggesting start-up firms should keep trademarks in-house.

This paper compares the merits of regional and firm based approaches for analysing the effect of agglomeration economies on firm deaths in Ireland. We aggregate a comprehensive data set on Irish firm deaths to Electoral Division (ED) level, the lowest geographical scale available. Estimates of the effect of agglomeration on firm deaths from a regional analysis at ED level using a cross-sectional spatial-autoregressive spatial error model are compared with firm-level estimates from a contemporary log-log model with spatially weighted agglomeration regressors. While estimates of the effects of agglomeration using these alternative methods is much discussed in existing literature rarely are the approaches or results compared. We show that contrasting results are found using the same data set dependent upon the unit of analysis used. Diversity lowers regional and firm deaths while specialisation raises regional deaths but lowers firm deaths. Greater urbanisation does not have a significant effect on firm hazard rates or equivalent regional estimates. While regional estimates provide evidence on the existence and nature of spatial dependence (negative in this case), firm estimates do not provide evidence that agglomeration in neighbouring regions is the source of this spatial dependence. No empirical analysis to our knowledge directly compares regional and firm based approaches for analysing the effect of spatial agglomeration economies on firm deaths.

Risk perception of SHS exposure has improved as has the gap in perception between smokers and nonsmokers. This research points to a lack of awareness among the general population of the risk perception of SHS exposure to children.

The hypothesis that flexibility enhances the long run prospects of the small firm is explored by examining precipitating causes of organizational change within it, and consequential adjustments. The study is fieldwork based and uses evidence gathered directly from entrepreneurs. New measures of flexibility and firm-specific turbulence are used to explain long-run performance, measured over 28 distinct attributes. Econometric estimates (using GLS and Heckman selectivity correction) are reported, on the relationship between flexibility, firm-specific turbulence and performance. Firm-specific turbulence is shown to have a negative effect on performance, but the latter is enhanced by increasing the flexibility of the small firm.
