Nou indicador per predir les empreses d'alt creixement
High-growth enterprises (HGEs) have a large economic impact but are notoriously hard to predict. Previous research has linked high-growth episodes to the configuration of lumpy indivisible resources inside firms, such that high capacity utilisation levels might stimulate future growth. We theorize that firms reaching critically high capacity utilisation levels reach a "trigger point" involving either broad-based investment in further growth or shrinking back to previous levels. We analyze EIBIS survey data (matched to ORBIS) which features a question on time-varying capacity utilisation. Overcapacity is a transitory state. Firms enter into overcapacity after a period of the rapid growth of sales and profits, and the years surrounding overcapacity have higher employment growth rates. Firms operating at overcapacity make incremental investments (e.g. capacity expansion, process improvements and modern machinery) rather than investing in R&D and new product development. We find support for the "fork in the road" hypothesis: for some firms, overcapacity is associated with launching into massive investments and subsequent sales growth, while for other firms, overcapacity is negatively related to both investments and sales growth.

No international tourists? How domestic destinations have competed for national tourists during COVID times.
The COVID-19 has caused a dramatic fall in international tourism demand. Destinations within countries have revised their promotion strategies, intensifying the competition for the domestic market, less affected by mobility restrictions. This paper proposes a contest theory model for characterizing this new context. Two types of destinations, coastal (sun and sand) and rural, compete for the existing demand in terms of promotion spending. The competition is driven by two main factors: the relative strategic advantage of each destination in the international and domestic markets and the strategic value given to each market. The pandemic has likely modified these factors, reducing the traditional advantage of coastal destinations and shifting the valuation towards the domestic market. According to the model, these changes may increase competition for the domestic market, with destinations rising promotion spending even in a context of reduced demand, which is consistent with the empirical evidence.

Les “ciutats intel·ligents” (smart cities) tenen de mitjana majors taxes de creació d'empreses
This paper investigates the relationship between the implementation of smart city initiatives and the number of new firms, paying special attention to the rates of green and digital entrepreneurship as smart cities tend to follow sustainable and/or digital orientations. We find evidence of a positive (causal) relation between smart city initiatives and entrepreneurship rates in a sample of Belgian municipalities, particularly when these initiatives follow a bottom-up approach and/or the level of implementation is high. In contrast, having sustainable and/or digital orientations in smart city initiatives does not generally make any difference in the rates of entrepreneurship, the exception being the digital rates in large municipalities. These results suggest that the smart city initiatives may be acting as a local entrepreneurship-supporting policy. They also support the view that smart cities are mainly (but not only) associated with technological developments (in large cities).

Gènere, diversitat professional d'equips d'R+D i generació de patents: una aplicació a empreses espanyoles
This paper studies the relationship between gender and occupational diversity in R&D teams and their capacity to generate patents. It is based on an extensive sample of 4,085 firms from the Spanish Community Innovation Survey over the 2004‒2014 period. Applying an exponential Poisson regression that controls for endogeneity through the generalised method of moments, the empirical results show that gender diversity has an ambiguous effect. Although it affects patents negatively, this impact is non-significant for patents with international protection. Patent generation is however positively affected by the diversity of categories in the R&D teams. Hence, the key question is not gender per se but rather the occupational status of the R&D teams.

Són efectives les zones de baixes emissions que s’estan aplicant massivament a les ciutats europees?
The great weight that the car has as a means of mobility in large cities generates significant negative externalities both in terms of pollution and congestion. The goal of this paper is to examine the effectiveness of low emission zones (LEZs) and to compare it with the existing results in literature on the effectiveness of urban tolls. First, we build up a theoretical model that departs from De Borger and Proost (2012), who study the effects of urban tolls on congestion, by incorporating pollution into the analysis and LEZs as an alternative (quantity-based) policy measure. Then we perform an econometric analysis taking advantage of a unique and extremely original panel of large European urban areas over the period 2008-2016, using data on congestion from TomTom and data on pollution (PM2.5) from environmental sciences. We conclude that LEZs can curb pollution. They are particularly effective in highly polluted cities, when they are applied to a wide area of the city, and/or when they are stringent in the type of restricted vehicles. Instead, LEZs are ineffective in mitigating congestion. This is a very relevant result, given the growing importance of LEZs in Europe.

Com potenciar el model del Tecnoparc
El Clúster TIC Catalunya Sud s’autodefineix “com una associació impulsada pel sector públic i liderada pel sector privat, amb el suport de la universitat Rovira i Virgili, que té com a objectiu promoure i contribuir a la competitivitat del sector de les Tecnologies de la Informació i Comunicació al Camp de tarragona i a les Terres de l’Ebre”. L’experiència del Tecnoparc és un bon exemple de l’enorme potencial, encara en part per explotar. “El model Tecnoparc funciona”, destaca Sergi Novo, al capdavant del Clúster.

3rd ECO-SOS Doctorials, 15 desembre 2021
L'ECO-SOS Doctorials és un workshop dissenyat per a millorar la formació dels estudiants de doctorat i difondre les seves activitats de recerca. En concret, aquests poden presentar treballs estàndard (presentació de 20 minuts) i idees de recerca (presentació de 5 minuts). A més a més, també hi ha una presentació d'un/una investigador/a sènior de l'ECO-SOS amb l'objectiu d'explicar la seva investigació. Aquest acte té lloc dos cops l'any: abans del PhD Workshop on Industrial and Public Economics (WIPE), al desembre, per tal que serveixi com a entrenament per als estudiants que hi participin, i abans de l'estiu, també com a entrenament abans del període en què es programen la majoria de congressos i workshops. El 3r ECO-SOS Doctorials se celebrarà el proper 15 de desembre a la Facultat d'Economia i Empresa de la Universitat Rovira i Virgili, a Reus. En aquesta edició comptarem amb 7 estudiants de doctorat que presentaran la seva recerca i tindrem una presentació final "European Radical Right Populist Parties in Government: Macroeconomic Impact" per part de Montserrat Ferré, membre sènior de ECO-SOS.
