Analysis of congress destinations' competitiveness using importance performance competitor analysis

To be competitive and successful in congress tourism, destinations must learn which congress tourism-related attributes are important and how they perform against their main competitors. This study identifies the importance and performance of destination attributes in Antalya, Turkey, and compares the position of these attributes to those of its main rival in congress tourism, ?stanbul. Importance performance competitor analysis results show that, according to domestic participants, Antalya has to focus on “sight-seeing and cultural attractions” and “outside entertainment.” For international participants, “climate,” “choice of meeting and housing properties,” and “suitability of conference facilities” exhibit higher performance in Antalya than ?stanbul.     

Operating Strategies for Battery Storage Systems in Low-Voltage Grids to Limit the Feed-In Power of Solar Power Systems Using Fuzzy Control

Germany’s energy turnaround is leading to an increasing integration of photovoltaics (PVs) throughout its distribution grid. To ensure safe grid operation in times of high solar radiation, PV plants must either be throttled back to comply with the feed-in limitation or store a portion of their excess electricity in batteries. This paper presents a grid-optimized operating strategy for PV storage systems based on a Fuzzy Logic Controller that reduces peak feed-in and thus also PV curtailment losses. The Fuzzy Logic Controller uses data on PV power surplus and battery charge level as input variables. To obtain good results, the set of numerical parameters of the membership functions is enhanced by evolutionary programming.The energetic assessment shows that even small electrical storage capacities (<<5?kWh) reduce curtailment losses considerably when using the grid-optimized operating strategy. The economic assessment shows that, in 2016, investments in PV storage systems with large PV plants and small batteries have small (positive) Internal Rates of Return. The system efficiency of the battery storage has a small impact on the profitability of PV storage systems, whereas the cycle stability and the electricity purchase price have a large impact. Moreover, there is an economic benefit for plant operators to switch from the simple to the grid-optimized operating strategy. Solar forecast inaccuracies and variations in load and generation profiles have a negligible impact on the performance of the control algorithm.     

Matching food security and malnutrition indicators: evidence from Southeast Asia

This article aims to understand the relation between household food security and individual undernutrition. The multitude of indicators available raises the question which aspects of food security are captured by the respective indicator. In our analysis, we first assess the relation between the dimensions of food security and households’ socioeconomic characteristics. Second, we examine whether household indicators detect undernutrition in children. Finally, we investigate the role of individual‐specific characteristics for child undernutrition. The analysis is based on a novel data set of 1,200 rural households from Cambodia and Lao PDR, which combines household‐ and individual‐level data. We capture household food security by three indicators including a dietary diversity score, a consumption behavior measure, and an experiential measure. Individual nutrition status is measured via anthropometric indicators. Our results show that different household‐level indicators capture fundamentally different aspects of food security. Moreover, household food security fails to explain stunting for children under five. Dietary diversity indicators, however, explain underweight in children to a small extent. We call for more research on intrahousehold allocation of food and stress the implications of our research for the design and targeting of food and nutrition support programs.     

Disentangling location-based advertising: the effects of location congruency and medium type on consumers' ad attention and brand choice

Research on location-based advertising (LBA) suggests that the merits of LBA lie in the fact that consumers can be targeted with location-congruent ads on their personal mobile devices. However, LBA consists of two underlying constructs: a mobile (vs. point-of-sales) advertising medium and location congruency (vs. location incongruency). This study aims to disentangle these underlying constructs by showing that they differentially affect the efficacy of an ad. Using a virtual reality lab experiment, this study shows that location-congruent ads result in increased choice for the target brand as compared to location-incongruent ads, independent of medium type. However, in location-incongruent situations, mobile ads attracted more attention than point-of-sales display ads. The advantages of LBA thus do not seem to emanate from medium type, but rather from the congruency between the ad and product location. When the ad is received at a different location than the product, the mobile medium is able to enhance consumers' ad attention.     

Nach der Wahl: Was sind die wichtigsten wirtschaftspolitischen Herausforderungen?

Even though Germany’s economy is currently going strong, the country still faces enormous challenges if it wants to maintain and increase this prosperity. The new government should take this opportunity to set the course for the future by encouraging the digitalisation of the economy and the society as well as by ensuring that the ongoing energy transition is sustainable and efficient. Other challenges include the adverse effects of globalisation on parts of society and the uneven distribution of income and wealth. But the actual magnitude of the government’s room to manoeuver is up for debate. The new government’s fiscal space might be more limited than it seems, since an automatic adjustment of the income tax to inflation and growth is required to end the bracket creep. Given that transfer programmes are being phased out, the federal income tax surcharge to finance German unification also needs to be abolished. Further budget pressure stems from the pension system and from demands by state and local as well as European governments. The new German government should use the next governing period to initiate fundamental reforms of economic and fiscal policy that will provide adequate answers to long-run challenges.     

Bitcoins,Blockchain und Distributed Ledgers

Cryptocurrencies such as bitcoin were invented to facilitate instant payment services without the need for a central bank or financial intermediaries executing payments. Using cryptographic functions, any user of the bitcoin system can transfer units of the virtual currency globally on an anonymous basis. However, financial supervisory authorities are about to increase regulation of virtual currencies due to concerns that the anonymous character of the system facilitates money laundering and the financing of illegal transactions. Nevertheless, the underlying blockchain technology, or in broader terms the distributed ledger technology, may revolutionise several industries. This paper illustrates the functioning and recent market developments in the bitcoin industry as well as the disruptive potential of the underlying technologies.     

Versuche,die Robustheit der deutschen Volkswirtschaft zu verstehen

GDP and employment in Germany have been improving since the economic and financial crisis. This paper investigates where this stability comes from. Michael Hüther does not believe that the cheap euro alone accounts for the high level of German competitiveness. He stresses unique German features such as the advantages of collaboration through social partnership and interconnected networks, as well as the flexibility of the economic sectors. In addition, German social stability plays an important role. He warns about the risks that would accompany a reversal of supply side political reforms, a lack of development of the country’s digital infrastructure and a failure to take coming demographic changes into account.     

Foreign direct investment via M&amp;A and domestic entrepreneurship: blessing or curse?

There are conflicting predictions in the literature about the relationship between FDI and entrepreneurship. This paper explores how foreign direct investment (FDI) inflows, measured by lagged cross-border mergers and acquisitions (M&A), affect entrepreneurial entry in the host economy. We have constructed a micro-panel of more than two thousand individuals in each of seventy countries, 2000–2009, linked to FDI by matching sectors. We find the relationship between FDI inflows and domestic entrepreneurship to be negative across all economies. This negative effect is much more pronounced in developed than developing economies and is also identified within industries, notably in manufacturing. Policies to encourage FDI via M&A need to consider how to counteract the prevailing adverse effect on domestic entrepreneurship.
