Labour adjustment costs: Estimation of a dynamic discrete choice model using panel data for Greek manufacturing firms

In this paper we estimate a dynamic structural model of employment at firm level. Our dataset consists of a balanced panel of 2790 Greek manufacturing firms. The empirical evidence of this dataset stresses three important stylized facts: (a) there are periods in which firms decide not to change their labour input, (b) there are periods of large employment changes (lumpy nature of labour adjustment) and (c) the commonality is employment spikes to be followed by smooth and low employment growth periods. Following Cooper and Haltiwanger [Cooper, R.W. and Haltiwanger, J. “On the Nature of Capital Adjustment Costs”, Review of Economic Studies, 2006; 73(3); 611–633], we consider a dynamic discrete choice model of a general specification of adjustment costs including convex, non-convex and “disruption of production” components. We use a method of simulated moments procedure to estimate the structural parameters. Our results indicate considerable fixed costs in the Greek employment adjustment.     

The impact of the Internet on human activity–travel patterns: analysis of gender differences using multi-group structural equation models

The widespread use of the Internet for conducting various types of activities may be leading to considerable change in people’s activity–travel patterns. Past studies, however, have left many issues unaddressed. Using an Internet-activity diary dataset and multi-group structural equation modeling, this study examines the complex interactions between different types of Internet and physical activities, with a special focus on gender differences and Internet maintenance and leisure activities. The results indicate that the impacts of Internet activities on people’s activity–travel patterns are significantly different across gender. In general, Internet use for maintenance purposes has a greater impact on women’s activity–travel in the physical world, while Internet use for leisure purposes affects men’s physical activities and travel to a greater extent. Further, breaking Internet activities down into different categories reveals some hidden patterns that would not have been detected if these different types of Internet activities were lumped together as a single category.     

The Competitiveness of Mobile Telephony across the European Union

This paper analyses the competitiveness of the mobile telecommunications industry across the European Union. A structural model of demand and supply has been estimated for annual data on 15 EU countries from 1998 to 2002. Estimates of country‐specific conjectural variations allow us to compare the competitiveness of mobile telephony across the EU, and can offer an alternative to the evaluation of competition based on direct cross‐country price comparisons. Average industry conjectural variations decrease over time as a result of regulation. The liberalization of fixed telephone lines and the introduction of number portability for mobiles increase the competitiveness of the mobile industry.     

The Persistence of Profits in the Long Run: A New Approach

We present a trend‐based alternative to the standard first‐order autoregression model in persistence of profits studies. This is motivated by reservations over the interpretation of the standard model, and rests on a different concept of dynamic competition. A nine‐category taxonomy of long‐run persistence stereotypes is developed. Structural time series estimates are presented for a sample of UK companies. We find the null of long run competitive equilibrium not rejected in nearly a third of cases, but non‐eroding persistence to be present in around 60%.     

关于日本经济长期停滞理论与政策的思考

泡沫危机以后,日本试图通过凯恩斯经济政策和结构改革的交替运用来恢复经济增长。20世纪90年代前期,凯恩斯经济政策的运用取得了短期效果。由于供给结构的变化,这一政策并没有使日本经济真正摆脱危机的困境。90年代后期,日本开始改为实施结构改革来提高其潜在增长率。由于总需求的持续减少,日本经济开始由短期衰退转为长期停滞。本文认为,泡沫危机后日本资产价格的持续下跌,导致各经济主体出现大量的不良资产,抵消了以上两大政策的经济效应。其中,商业银行对不良债权处理的拖延造成供给结构效率下降、企业投资和个人消费持续减少,使日本经济的停滞趋于长期化。     

Can good marketing carry a bad product? Evidence from the motion picture industry

We examine the relative roles of marketing actions and product quality in determining commercial success. Using the motion picture context, in which product quality is difficult for consumers to anticipate and information on product success is available for different points in time, we model the effects of studio actions and movie quality on a movie’s sales during different phases of its theatrical run. For a sample of 331 recent motion pictures, structural equation modeling demonstrates that studio actions primarily influence early box office results, whereas movie quality influences both short- and long-term theatrical outcomes. The core results are robust across moderating conditions. We identify two data segments with follow-up latent class regressions and explore the degree of studio actions needed to “save” movies of varying quality. We finally offer some implications for research and management.     

中美双边工业品增加值贸易隐含碳福利核算与分配问题研究

现代贸易方式不仅导致贸易利益在全球价值链上进行分配,还带来了贸易隐含污染排放在全球贸易网络中的分布。两国之间的贸易利益分配除了表现为贸易经济福利的分配,还表现为贸易隐含碳福利的分配。本文将贸易增加值分解法结合MRIO模型对2000—2014年中美双边工业品贸易增加值所隐含的碳福利分配及影响机制展开深入分析。研究结果表明:(1)在中美双边工业品增加值贸易隐含碳福利分配中,碳福利逆差在中国,碳福利顺差在美国;(2)中美工业品贸易碳福利级差经历了“先扩大,后收窄”的过程,美国次贷危机之后双边碳福利不平衡状况重新呈现扩大趋势;(3)中国碳排放强度下降、价值链地位提升以及对美进口规模扩大都有助于改善碳福利逆差的局面,但美国对中国不断扩大的中间品和最终品需求以及双边复杂的技术关联结构仍是中国碳福利逆差的主导因素;(4)全球价值链的深化可能将导致对出口国加征关税会通过降低进口消费侧排放的方式恶化加征国的贸易隐含碳福利。本文研究的时间范围同时覆盖中国加入WTO以及美国次贷危机两个重要节点,这对于重新审视中美经贸关系新格局下双边贸易隐含碳福利分配构建了一个新的分析视角,为中美未来贸易谈判以及全球碳排放责任认定提供了一个新的解读方向。     

产业结构失衡与调整的市场机制研究——山西产业结构调整的再思考

在我国特别是在资源型地区,由于市场机制调节产业结构的机制存在要素自由流动不畅、利益机制传导受阻、核心技术缺乏等问题,使市场机制作用的发挥受到较大影响,导致这些地区往往存在严重的产业结构失衡与产业升级较慢等问题。当前,资源性经济景气下降,诸如山西这样资源型地区的"寒号鸟"们再次感受到了冬天的寒冷,又到了市场倒逼机制开始发挥作用的时期。在这个时期,需抓住我国深入市场化改革的机遇,破除阻碍市场调节产业结构调整机制的多重障碍,通过发展混合所有制经济、激活国企利益机制功能和创新科研机制确立核心技术研发主体等措施,完善市场调节机制,推进地区产业结构调整,走出"调整-反弹-再调整"的结构调整怪圈。     

Cross-ownership as a structural explanation for over- and underestimation of default probability

Based on the work of Suzuki, we consider a generalization of Merton’s asset valuation approach in which two firms are linked by cross-ownership of equity and liabilities. Suzuki’s results then provide no arbitrage prices of firm values, which are derivatives of exogenous asset values. In contrast to the Merton model, the assumption of lognormally distributed assets does not result in lognormally distributed firm values, which also affects the corresponding probabilities of default. In a simulation study we see that, depending on the type of cross-ownership, the lognormal model can lead to both over- and underestimation of the actual probability of default of a firm under cross-ownership. In the limit, i.e. if the levels of cross-ownership tend to their maximum possible value, these findings can be shown theoretically as well. Furthermore, we consider the default probability of a firm in general, i.e. without a distributional assumption, and show that the lognormal model is often able to yield only a limited range of probabilities of default, while the actual probabilities may take any value between 0 and 1.     

Quality,Satisfaction and Customers’ Future Intention: The Case of Hotels’ Fitness Centers in Cyprus

In an era of fierce competition, financial hardship, and volatile customer expectations the hospitality industry is seeking out new revenue centers that can both enrich the customer experience, and contribute to financial success. Capturing the attention of the industry, fitness centers have become a fundamental component of the contemporary hospitality experience with numerous strategic, operational and tactical implications. Responding to the need for further empirical investigation, the study, by adopting a quantitative methodology, holistically investigates quality, satisfaction, and behavioral intention in fitness centers currently operating in upscale hospitality establishments in Cyprus. Findings suggest that satisfaction with the provision of fitness services in hotels is primarily associated with the dimensions of employee behavior and workout facilities. Moreover, workout facilities was the only quality dimension which was significantly associated with the respondents’ intention to renew their membership, whereas a strong relationship between satisfaction and future intention was substantiated.
