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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

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. 相似文献

The objective of this research is to examine the role of sector-specific information technology (IT) developments and their significance in terms of the revenue and earnings before tax of Logistics Service Providers (LSPs), as well as the impact of these developments on the flexibility and integration of LSPs. A survey questionnaire was conducted with 284 LSPs participants. The data provided by the 51 responding enterprises provided a representative sample for the analysis of the sample population and the drawing of general and relevant conclusions related to basic population. It can be concluded that their revenue, earnings before tax and degree of integration into the supply chain depend on the sector-specific IT developments carried out by the given enterprise. IT investments will remain important in the future and the introduction and leveraging the best technologies may yield competitive advantages and higher financial rewards for LSPs. 相似文献
