Has Austria’s Accession to the EU Triggered an Increase in Competition? A Sectoral Markup Study

We estimate the pro-competitive effects of Austrias participation in the Single Market after its European Union (EU) accession in 1995 in terms of firms market power as measured by the Lerner index, using a sample of 46 industries and 7 industry groups, covering the period 1978–2001. In the framework of the markup estimation method suggested by Roeger (1995), we test for both an instantaneous structural break between 1993 and 1998 and also estimate logistic smooth transition models to take up the proposition that the regime shift is likely to have occurred gradually rather than as a big bang. In sum, the results provide no reason for being euphoric: Pronounced markup reductions were only found in three industry groups (mining and quarrying, wholesale and retail trade; financial services and real estate). At the more disaggregate level, the picture is mixed: Both increases and reductions in market power have been found.

Network externalities and long-run market shares

We study a dynamic duopoly model with network externalities. The value of the product depends on the current and past network size. We compare the market outcome to a planner. With equal quality products, the market outcome may result in too little standardization (i.e. too many products active in the long run) but never too much. The potential inefficiency is non-monotonic in the strength of the network effect, being most likely for intermediate levels. When products differ in quality, an inferior product may dominate even when the planner would choose otherwise, but only if the discount factor is sufficiently large     

融资成本、寻租行为和企业内部资本配置

本文构造了一个两层次委托代理模型,强调了外部资本市场和内部资本市场之间的相互作用,分析表明,资本配置扭曲和资本使用效率低下的关键是外部资本市场运作不完善对企业内部管理者的寻租行为的影响。本文的分析表明,融资成本偏低的外部资本市场不仅会促使企业CEO过分扩大融资规模,而且会加剧企业内部管理者的寻租行为,导致资本配置不当、投资缺乏效率的不良后果。本文的政策含义是,必须改变融资成本偏低的现状,并加强公司治理结构建设,才能解决我国企业融资过热、资本使用效率低下等一系列问题。

Traders’ choice between limit and market orders: evidence from NYSE stocks

In this paper, we examine a trader's order choice between market and limit orders using a sample of orders submitted through NYSE SuperDot. We find that traders place more limit orders relative to market orders when: (1) the spread is large, (2) the order size is large, and (3) they expect high transitory price volatility. A rise in informational volatility appears neither to increase nor decrease the placement of limit orders. We also find that a rise in lagged price volatility decreases the size of spread, which is driven by the increase in the placement of limit orders.
