In Search of the Transmission Mechanism of Fiscal Policy in the Euro Area

This paper applies the DSGE‐VAR methodology to assess the size of fiscal multipliers in the data and the relative contributions of two transmission mechanisms of government spending shocks, namely hand‐to‐mouth consumers and Edgeworth complementarity. Econometric experiments show that a DSGE model with Edgeworth complementarity is a better representation of the transmission mechanism of fiscal policy as it yields dynamic responses close to those obtained with the flexible DSGE‐VAR model (i.e. an impact output multiplier larger than one and a crowding‐in of private consumption). The estimated share of hand‐to‐mouth consumers is too small to replicate the positive response of private consumption. Copyright © 2016 John Wiley & Sons, Ltd.     

‘Stop Being a Tourist!’ New Dynamics of Urban Tourism in Berlin‐Kreuzberg

Berlin is witnessing a massive tourism boom, and parts of it can be described as ‘new urban tourism’, which shows a preference for off the beaten track areas and ‘authentic’ experiences of the city. This form of tourism seems especially salient in Kreuzberg. It is here that an openly articulated critique of tourism attracted national attention in 2011 and has not ceased to do so since. This article aims to better understand the conflictive potential of (new urban) tourism in Kreuzberg. We argue that the readily expressed negative attitudes against tourists and the easily accepted link between tourism and gentrification have to be explained against the backdrop of certain housing‐market dynamics. Rising rents and a diminution in the number of flats available for rent are fuelling fears of gentrification in Kreuzberg, while the interest shown in new urban tourism and the comparatively low‐priced real‐estate market in Berlin result in a growing number of holiday flats. Although adding only slightly to the tightening of the housing market, holiday flats render complex processes of neighborhood change visible and further sustain an already prevalent tourism critique.     

Integrating the Social Structure of Accumulation and Social Accounting Matrix with the Social Fabric Matrix

The purpose here is to elaborate on the social fabric matrix approach (SFM‐A), and to assess the possibility of integrating it with the social structure of accumulation and the social accounting matrix.The SFM‐A to analysis and policy evaluation allows for cultural values, social beliefs, institutions, attitudes, technology, and the ecological system to be modeled into a system. The guiding goal is to work toward a more complete model of the provisioning process.     

Migration,Friendship Ties,and Cultural Assimilation

We study immigrant assimilation by analyzing whether friendship with natives is a measure of cultural assimilation, and by investigating the formation of social ties. Using the German Socio‐Economic Panel, we find that immigrants with a German friend are more similar to natives than those without German friends, along several important dimensions, including concerns about the economy, an interest in politics, and a host of policy issues. Turning to friendship acquisition, we find that becoming employed, time spent in the host country, the birth of a child, residential mobility, and additional education acquired in the host country are significant drivers of social network variation.     

WHICH AGGLOMERATION EXTERNALITIES MATTER MOST AND WHY?

This paper revisits the ongoing discussion on the importance of agglomeration externalities – specifically specialization, diversity and competition effects – that may contribute to innovation, productivity and urban employment growth. Previous meta‐analyses suggested that the evidence on agglomeration externalities is strongly context‐specific. Expanding an earlier analysis of 31 articles, we seek to draw in this paper more robust conclusions by means of the statistical evidence for agglomeration externalities presented in 73 scientific articles, all building on the seminal work of Glaeser et al. (1992). Our results confirm that the heterogeneity among studies is huge and can only be partially accounted for by means of an ordered probit analysis. Additionally, some evidence of publication bias is found. We conclude that the conventional lines of inquiry in this literature may now have reached strongly diminishing returns. New lines of inquiry, using rich micro‐level data on firms and workers, dynamic general equilibrium models at the macro level, more attention for spatial and temporal variation in the impacts of agglomeration, and further investigations into the spatial scope of externalities are promising avenues for further research that can enhance our understanding of how agglomeration externalities continue to fuel our increasingly urbanized world.     

Hospital costs associated with thyroidectomy performed with a Harmonic device compared to conventional techniques: a systematic review and meta-analysis

Objectives: Harmonic devices have become a world-wide standard for dissection and hemostasis in thyroidectomy. Numerous systematic reviews have reported superior operating times, blood loss, post-operative pain, length of stay, and overall safety outcomes. What has not been extensively evaluated in a robust manner is their economic impact. The purpose of this study is to evaluate the hospital costs associated with open thyroidectomy using Harmonic devices compared with conventional techniques for hemostasis. Methods: A systematic review of Medline, Scopus, and CENTRAL was performed from January 1, 2000 to May 23, 2014 without language restrictions for randomized clinical trials comparing Harmonic surgical devices to conventional methods in thyroidectomy. The main outcome measure was total reported costs. Costs were pooled using the ratio of means and a random effects model. Sensitivity analyses assessed whether differences in patient and trial characteristics, healthcare setting, or choice of statistical model affected outcomes. Results: Seven studies met the inclusion criteria. A total of 476 participants had procedures performed with Harmonic devices and 478 with conventional monopolar electrosurgery and clamp, cut and tie techniques. Compared with conventional techniques, Harmonic devices reduced total reported costs by 10% (p?=?0.007), resulting in a $229?US dollars (USD) absolute reduction from mean baseline costs. Results remained relatively robust to additional sensitivity analyses. Conclusions: This systematic review and meta-analysis demonstrates that the Harmonic family of surgical devices is associated with a reduction in total reported costs in thyroidectomy compared with conventional techniques. A large portion of the overall savings derives from a reduction in operative costs.     

What drives the effectiveness of industrial clusters? Exploring the impact of contextual,structural and functioning determinants

This study examines how contextual, structural and functioning characteristics of industrial clusters influence their effectiveness. We develop a conceptual framework that identifies potential influencing factors, validate the factors statistically, and estimate the factors’ impact on cluster effectiveness. Our results show that among the important determinants of cluster effectiveness are long-term planning security and procedural trust among the cooperating firms (contextual conditions), formalized rules and sustainable structures (structural elements), and clear goals and tasks (functioning characteristics). However, the results also reveal that some determinants assessed as important in the literature do not seem to have a positive impact on effectiveness. Our results not only modify general assumptions in cluster research concerning the drivers of cluster effectiveness, but also assist firms and policy-makers in conceptualizing successful new clusters.     

Nothing Tastes as Local: Jordanians’ Perceptions of Buying Domestic Olive Oil

To date, little is known about how consumers perceive local and foreign olive oil. This study was conducted with the intention of exploring key trends in Jordanian consumers’ perceptions toward local olive oil and to examine whether they are ethnocentric toward purchasing their local olive oil in the era of the Arab Spring. The research design is a combination of quantitative with a qualitative technique to support and expand on the research findings. Data were collected from a total number of 196 Jordanians who live in Amman city. The results revealed that Jordanians are loyal to their country’s olive oil; they expressed strong ethnocentric tendencies toward purchasing it, and their purchasing tendencies are influenced by nationalism. Jordanians ranked their local olive oil as the best worldwide. This article provides original insights into the development and marketing strategies for local and global olive oil producers in the Jordan market and other Arab country markets.
