The role of psychological and socio-demographical factors for electric bike use in Norway

The electric bike (e-bike) is emerging as a new sustainable transport mode in Norway and has the potential to lead to increased cycling among the population. However, little is known about psychosocial determinants of e-bike use. The aim of the study was to examine the role of normative and environmental beliefs, the perceived attributes of e-bikes, and innovativeness and demographical factors related to e-bike use in a Norwegian sample. An online survey was used to collect data from 910 respondents, including both e-bike users (252) and non-users (658). The respondents were recruited via a commercial panel (response rate 42.04%) and a Facebook post. A structural equation modeling analysis was used to analyze the data. The structural model had a good fit to the data. The results showed that attitudes towards e-bike use followed by innovativeness were the most important predictors of e-bike use. The normative processes measured within the Norm Activation Model activated positive attitudes towards e-bike use, which in turn predicted e-bike use. There was a negative relationship between e-bike and conventional bike use, while a positive relationship was found between car and e-bike use. The results are discussed with regard to their implications for interventions aiming to promote e-bike use.     

Economic diversification of a single-asset tourism city: evidence from Antalya†

It is often argued that the growth of single-asset tourism places is fragile because it is vulnerable to economic fluctuations and is based on specialization and localization economies that lead to an ever stronger lock-in process of path-dependent urban economic development and, in the end, slow growth. In this paper, it is doubted whether a high urban tourism growth implies an ever stronger specialization and an ever stronger lock-in. This paper shows that the growth of tourism stimulates the growth of related and unrelated industries and generates a diversification of the economy, even though some other sectors are crowded out. Antalya (Turkey) is selected as a case-study area not only because its economy is dominated by tourism (it is a good example of a single-asset tourism city), but also because its economy shows a tendency to economic diversification at the sectoral level. This diversification tendency is shown by means of a shift-share analysis and Herfindahl indexes.     

Price Rigidity in Turkey: Evidence from Micro Data

In this study we investigate the duration of consumer price spells and price change patterns for Turkey by employing a comprehensive micro price data covering around 6,000 items over four years. In detail, we analyze how long typical price spell lasts and we investigate the size, frequency, distribution and synchronization of price changes. Compared to advanced economies, a higher frequency of price changes is estimated. Findings suggest substantial heterogeneity among sub-groups in terms of frequency and synchronization indicators. The mixed evidence of both state and time-dependent pricing is also relevant for Turkey, an emerging market economy.     

扁平证券市场线和融资限制——中国股票市场的实证检验

资本资产定价模型（CAPM)在国际金融市场的实证检验结果往往呈现扁平证券市场线现象。一些学者认为融资限制是该现象的产生原因。本文旨在研究扁平证券市场线现象是否存在于中国股市,同时分析融资限制对中国股市证券市场线的影响。本文采用投资组合分析法对A股主板市场进行实证检验。本文研究发现：（1)扁平的证券市场线现象同样存在于中国股票市场中;（2)在中国股票市场中,融资限制与证券市场线的斜率呈负相关,与截距呈正相关,这符合融资限制理论;（3)以上两点发现同样存在于多因子定价模型中,这表明本文研究结果具有稳健性。       

The New Game in Town: Competitive Effects of IPOs

We analyze the effect of initial public offerings (IPOs) on industry competitors and provide evidence that companies experience negative stock price reactions to completed IPOs in their industry and positive stock price reactions to their withdrawal. Following a successful IPO in their industry, they show significant deterioration in their operating performance. These results are consistent with the existence of IPO‐related competitive advantages through the loosening of financial constraints, financial intermediary certification, and the presence of knowledge capital. These aspects of competitiveness are significant in explaining the cross‐section of underperformance as well as survival probabilities for competing firms.

The impacts of bank-specific and macroeconomic variables on the capital adequacy ratio: evidence from Islamic banks

The study investigates the relationship between the capital adequacy ratio (CAR) and different bank-specific and macroeconomic variables for 28 Islamic banks. We document that there is a statistically significant positive relationship between the CAR and the bank-specific and macroeconomic variables. In particular, bank-specific variables such as ROA, ROE, leverage, credit risk and size show a strong association with the CAR, while on the macroeconomic side, inflation, market capitalization and exchange rate have an impact on the average Islamic bank in our sample study. Furthermore, we run another model (equity to assets ratio) as dependent, with similar control variables, and the results reveal that, except for inflation, all the variables that have a significant effect on the CAR also influence the equity to assets ratio.     

Why (not) cooperate? A cognitive model of farmers’ intention to join producer groups in Romania

After the breakdown of the communist regime in Romania, collective farms were replaced by a large number of small-scale private farms. Although cooperation seems to be a favourable choice for these smallholders, it did not develop as perhaps expected. This article explores the factors that determine the formation of the intention of Romanian vegetable farmers to join marketing cooperatives in the form of so called producer groups. Our theoretical framework refers to Ajzen’s Theory of Planned Behaviour, which we model with a structural equation model. We identified as main intention drivers the expectation for better prices and easier access to capital. Perceived family support is another significant factor. The level of distrust is high. Although our trust variable is not significant as a predictor of the intention to cooperate in the model, we find qualitative indications that trust plays a role when the intention is translated into actual behaviour.     

Handelsblatt Ranking and Journal Quality: A Cautionary Note

I provide a brief discussion of the Handelsblatt ranking by focusing on its journal quality weights. I summarize the methodology underlying journals’ prestige measure, which is derived from their citation networks, and discuss its strengths and shortcomings. Although I agree that Handelsblatt ranking provides a great service to the profession, that same profession needs to be rather careful not to overemphasize the journal quality weights.
