Modelling innovation support systems for regional development – analysis of cluster structures in innovation in Portugal

The present article offers a concise theoretical conceptualization and operational analysis of the contribution of innovation to regional development. The latter concepts are closely related to geographical proximity, knowledge diffusion and filters and clustering. Institutional innovation profiles and regional patterns of innovation are two mutually linked, novel conceptual elements in this article. Next to a theoretical framing, the article employs the regional innovation systems concept as a vehicle to analyse institutional innovation profiles. Our case study addresses three Portuguese regions and their institutions, included in a web-based inventory of innovation agencies which offered the foundation for an extensive database. This data-set was analysed by means of a recently developed principal coordinates analysis followed by a Logistic Biplot approach (leading to a Voronoi mapping) to design a systemic typology of innovation structures where each institution is individually represented. There appears to be a significant difference in the regional innovation patterns resulting from the diverse institutional innovation profiles concerned. These profiles appear to be region specific. Our conclusion highlights the main advantages in the use of the method used for policy-makers and business companies.     

International capital flows under dispersed private information

It is well established that private information is critical to our understanding of asset prices. In this paper we argue that it also affects international capital flows and use a simple two-country DSGE model to illustrate its impact. We show that private information (i) increases the volatility of both net and gross capital flows, (ii) leads to a high correlation between capital inflows and outflows, (iii) leads to a disconnect of capital flows from observed macro fundamentals and (iv) implies that capital flows contain information about the future macro fundamentals. We also show that dispersed information affects capital flows both through asset prices and directly, so that the impact on flows is not just the mirror image of the impact on prices.     

Using Experimental and Neurological Data to Gain a Deeper Understanding of Realization Utility Theory

Starting with the premise that realization utility theory helps explain trading behavior, this study combines a carefully crafted experimental design with functional magnetic resonance imaging technology to offer a more inclusive examination of factors that affect REIT trading behavior beyond whether a REIT is simply trading up or down. We add to the nascent field of neurological real estate by finding that local gains/loss domains are more relevant than are global gain/loss considerations, financial skewness is a significant determinant of trading behavior, and that performance inside the REIT market influences how hard subjects think when performing tasks outside the market.

Cost-effectiveness analysis of rivaroxaban for treatment and secondary prevention of venous thromboembolism in the Netherlands

Background: Until recently, standard treatment of venous thromboembolism (VTE) concerned a combination of short-term low-molecular-weight heparin (LMWH) and long-term vitamin-K antagonist (VKA). Risk of bleeding and the requirement for regular anticoagulation monitoring are, however, limiting their use. Rivaroxaban is a novel oral anticoagulant associated with a significantly lower risk of major bleeds (hazard ratio?=?0.54, 95% confidence interval?=?0.37–0.79) compared to LMWH/VKA therapy, and does not require regular anticoagulation monitoring.

Aims: To evaluate the health economic consequences of treating acute VTE patients with rivaroxaban compared to treatment with LMWH/VKA, viewed from the Dutch societal perspective.

Methods: A life-time Markov model was populated with the findings of the EINSTEIN phase III clinical trial to analyze cost-effectiveness of rivaroxaban therapy in treatment and prevention of VTE from a Dutch societal perspective. Primary model outcomes were total and incremental quality-adjusted life years (QALYs), as well as life expectancy and costs.

Results: Over a patient’s lifetime, rivaroxaban was shown to be dominant, with health gains of 0.047 QALYs and cost savings of €304 compared to LMWH/VKA therapy. Dominance was robustly present in all sensitivity analyses. Major drivers of the differences between the two treatment arms were related to anticoagulation monitoring (medical costs, travel costs, and loss of productivity) and the occurrence of major bleeds.

Conclusion: Rivaroxaban treatment of patients with venous thromboembolism results in health gains and cost savings compared to LMWH/VKA therapy. This conclusion holds for the Dutch setting, both for the societal perspective, as well as the healthcare perspective.     

Modelling Inflation Volatility

This paper discusses estimation of US inflation volatility using time‐varying parameter models, in particular whether it should be modelled as a stationary or random walk stochastic process. Specifying inflation volatility as an unbounded process, as implied by the random walk, conflicts with priors beliefs, yet a stationary process cannot capture the low‐frequency behaviour commonly observed in estimates of volatility. We therefore propose an alternative model with a change‐point process in the volatility that allows for switches between stationary models to capture changes in the level and dynamics over the past 40 years. To accommodate the stationarity restriction, we develop a new representation that is equivalent to our model but is computationally more efficient. All models produce effectively identical estimates of volatility, but the change‐point model provides more information on the level and persistence of volatility and the probabilities of changes. For example, we find a few well‐defined switches in the volatility process and, interestingly, these switches line up well with economic slowdowns or changes of the Federal Reserve Chair. Moreover, a decomposition of inflation shocks into permanent and transitory components shows that a spike in volatility in the late 2000s was entirely on the transitory side and characterized by a rise above its long‐run mean level during a period of higher persistence.

Going Native: Effects of Disclosure Position and Language on the Recognition and Evaluation of Online Native Advertising

Despite recent industry attention, questions remain about how native advertising is perceived and processed by consumers. Two experiments examined effects of language and positioning in native advertising disclosures on recognition of the content as advertising, effects of recognition on brand and publisher evaluations, and whether disclosure position affects visual attention. Findings show that middle or bottom positioning and wording using “advertising” or “sponsored” increased advertising recognition compared to other conditions, and ad recognition generally led to more negative evaluations. Visual attention mediated the relationship between disclosure position and advertising recognition. Theoretical, practical, and regulatory implications for disclosures in native advertising are discussed.     

Are stricter investment rules contagious? Host country competition for foreign direct investment through international agreements

We argue that competitive diffusion is a driver of the trend toward international investment agreements with stricter investment rules, namely defensive moves of developing countries concerned about foreign direct investment (FDI) diversion in favor of competing host countries. Accounting for spatial dependence in the formation of bilateral investment treaties and preferential trade agreements that contain investment provisions, we find that the increase in agreements with stricter provisions on investor-to-state dispute settlement and pre-establishment national treatment is a contagious process. Specifically, a developing country is more likely to sign an agreement with weak investment provisions if other developing countries that compete for FDI from the same developed country have previously signed agreements with similarly weak provisions. Conversely, contagion in agreements with strong provisions exclusively derives from agreements with strong provisions that other FDI-competing developing countries have previously signed with a specific developed source country of FDI.     

From ‘just a swimmer’ to a ‘swimming mother’: women’s embodied experiences of recreational aquatic activity with pre-school children

Increased academic attention on the gendering of leisure pastimes in recent years has highlighted the centrality of the gendered body in influencing how leisure is accessed, experienced and transformed. To date, however, little attention has been paid to how women experience aquatic leisure activity, the second most popular form of leisure activity in the UK, and where female participation predominates. This paper presents results from research investigating the aquatic leisure experiences of 22 women, with children aged under 3, in the North-East of England. A number of key themes emerged from the data, which highlighted the centrality of the gendered, lived body as a key social construct contouring participant perceptions in the swimming pool environment. Women reflected upon their self-perceived physical deficiencies when wearing revealing swimming costumes, particularly under the critical gaze of ‘other’ bodies, whether present or imagined. The co-presence of other bodies was also central in shaping lived experiences, and the presence of ‘dependent’ children’s bodies shifted bodily intentionality away from the self towards perceived maternal responsibilities and the management of perceived risks, including ‘dirt’ and ‘germs’ and the negotiation of the tacit rules of the swimming pool. Results also suggest that the emphasis on maternal responsibility in aquatic leisure activity and timing of parent-toddler sessions could lead to reproduction of gender inequalities and the exclusion of some fathers from participation.
