How much are sellers willing to pay for the features offered by their e-commerce platform?

The success of an e-commerce platform is significantly dependent on the number of sellers and their quality. Thus, it is important to understand the factors that influence a seller's platform choice. This paper investigates features of an e-commerce platform on which sellers place high value when choosing a platform to sell their products, using a conjoint analysis. The data was collected by online survey from 1,796 sellers who are using Naver Smart Store (https://sell.smartstore.naver.com), which is one of the largest e-commerce platform in South Korea. After analyzing the willingness to pay for each combination of functions by separating six functions of Naver Smart Store, it was estimated that the MWTP ranged 3.05 to 4.48 for the main process related functions and 2.61–5.3 for the sub process related functions. MWTP can be considered as a benefits for the sellers since Naver does not require monetary commissions from sellers. This paper also shows that the higher technical understanding of the functions provides the more value to platform to sellers.

Transactional analysis training for the travel industry

This article describes the applications of Transactional Analysis (TA) — a technique developed originally by Eric Berne as a simplified approach to psychotherapy — to various activities within travel and tourism organizations such as: supervising personnel, developing better relations with customers, and improvement of interpersonal communication and feelings. The process of TA training in tourism/hospitality enterprises is analyzed and the uses of it are described.     

Moving toward the EU or the Middle East? An assessment of alternative Turkish foreign policies utilizing the GTAP framework

This paper assesses the new orientation in Turkish foreign policy towards the Arab world by analyzing the potential impact of Turkey’s membership in either the European Union (EU) or the Greater Arab Free Trade Area (GAFTA). We utilize the most recent version of the Global Trade Analysis Project (GTAP) database, its global Computable General Equilibrium (CGE) model, and the gravity border effect approach to estimate the ad-valorem tariff equivalents (AVEs) of non-tariff barriers (NTBs). In our overall analysis, we account for 24 various sectors. However, in our evaluation, we focus primarily on the food and agricultural sectors because this sector is characterized by high tariff and non-tariff protection. In the CGE simulation analysis, we consider the removal of tariffs and NTBs simultaneously. After projecting the GTAP framework to 2020, we conclude that Turkey would gain unambiguously from EU membership, whereas Turkey’s gains from GAFTA membership would be more limited. The paper also presents that the welfare gains from the removal of NTBs are of considerable importance and would generally be greater than the gains stemming from the elimination of import tariffs.

Consumers’ response to the EU Quality policy allowing for heterogeneous preferences

Using dry-cured ham as an anchor product, consumers’ preferences for EU Quality Certification schemes, region of origin and price have been investigated with conjoint analysis. In order to achieve this aim, a mixed rank-ordered logit which allows for the investigation of heterogeneous preferences and their sources has been estimated. In particular, we have analysed to what extent consumers’ socio-demographic traits affect their price-sensitiveness and whether consumers’ sensory (hedonic) valuations and attitudes towards ham with a Protected Designation of Origin (PDO) affect the preferences for specific attributes. Results show that consumers with a low-medium age and income are more price sensitive. Consumers more inclined sensorially towards the regional specialty (with or without PDO) are more likely to purchase this product, and consumers with a more favourable attitude towards PDO ham are also more prone to purchase cured ham with quality certification. Findings also suggest that although the PDO scheme attracts a segment of consumers, the origin by itself is still a more powerful signal of quality, and more specifically the region of origin.     

Assessing the efficiency of switchgrass different cultural practices for pellet production

Switchgrass is a perennial crop producing high amounts of biomass for good quality pellet production. The objective of this study is to examine the efficiency of different cultural practices of switchgrass for pellet production under field conditions for four different N-fertilization (0, 80, 160 and 240 kg ha⁻¹) and two different irrigation levels (0 and 250 mm), in two soils in central Greece with rather different moisture status over the period 2009–2012. Moreover, comparison between three harvest methods (two different types of bales and silage) was made. The results derived from this study revealed that the bale at 22 kg is the harvesting practice with the highest costs while there was reduction of efficiency scores when nitrogen levels increased. At both environments the efficiency scores followed the same trend, confirming that low levels of nitrogen fertilization enhance the economic competitiveness of switchgrass production. Palamas site is the area where switchgrass for pellet production had positive income ranging from 400 to 1600 € ha⁻¹, while Velestino site had always negative. Therefore, places like Velestino with non-aquic soil should be avoided for switchgrass. These data suggest that growing switchgrass for solid biofuel production as energy crop is a worthwhile decision only in areas with a moderately shallow groundwater table (aquic soil) or maybe in high precipitation regions.

劳动力成本上升对不同规模企业创新行为的影响

现有研究认为劳动力成本上升会倒逼企业创新,但该结论主要基于规模以上企业实证研究,难以考察劳动力成本上升对不同规模企业创新行为的异质性影响。基于严格随机分层抽样的“中国企业-员工匹配调查”数据（CEES）,对劳动力成本上升背景下不同规模企业创新行为的异质性影响进行了大样本实证研究。将新产品推出速度作为企业创新的代理变量,研究发现劳动力成本上升对企业创新行为的影响在不同规模企业之间存在明显差异。大型企业创新速度显著加快,而中小企业的创新行为并未发现明显变化。进一步分析认为,之所以存在劳动力成本上升对中小企业创新的“倒逼失灵”现象,技能劳动力缺乏、职业培训投入不足和创新资金基础薄弱或是重要原因。
