ETF Competition and Market Quality

This paper examines competition between exchange traded funds (ETFs) that hold nearly identical portfolios of securities. We provide evidence that incumbent‐fund liquidity is negatively affected when a new ETF is added to an asset class. The degradation in liquidity is even more severe whenever both funds follow the same benchmark. We also document a decline in primary‐market activity for the incumbent ETFs after the arrival of new competitors. Furthermore, increasing the number of funds in an asset class does not put downward pressure on fund management fees. Thus, the deterioration in market quality may not be offset by decreasing costs of fund ownership.     

The death of firms: exploring the effects of environment and birth cohort on firm survival in Sweden

This paper investigates the death of firms and seizes a long-term perspective. It investigates the life spans of nearly 2,200 firms in seven birth cohorts of Swedish joint-stock companies, founded during seven separate years between 1899 and 1950. Research has traditionally emphasized individual- and micro-oriented factors in explaining post-entry performance, or has often focused on the influence of firm-specific structural factors (firm age and size). A less attended field recognizes environmental forces. This paper focuses on the interaction between the micro and macro levels, and combines structural and environmental factors. Employing a cohort approach, it relates firm survival to firm age and size, as well as to the effect of cohort affiliation and environmental change over time (period effects). During macroeconomic expansion, the risk of death decreases. Cohort effects are also evident. Firms founded during times of economic crisis exhibit lower survival rates. Consequently, cohort affiliation and environmental forces, i.e. period effects, can explain differences in death rates in different firm populations.

Bring in the brewers: business entry in the Swedish brewing industry from 1830 to 2012

This article analyses long-term business entry in the Swedish brewing industry, presenting new data on its organisational historiography. Since 1830, the rate of entry has varied considerably; entries increased progressively from the 1850s, and fell at a decreasing rate from the early twentieth century. An increasing tendency to enter the trade can be observed from the mid-1980s – in particular, there has been a considerable resurgence since the turn of the millennium. The article elaborates on explanations that are both exogenous and endogenous. Above all, the results provide support for the role of endogenous conditions. The results should be viewed as complementary to previous analyses of the (Swedish) brewing industry, which either have employed shorter analytical time-frames or have mainly focused on the role of exogenous conditions, such as changes in the institutional framework.     

正确对待企业改革,管理和发展的关系

本文用新型管理哲学—耗散结构理论阐述了企业的改革、管理与发展的关系。文中指出,改革和管理是企业发展不可缺少的两个重要途径。企业的发展是永恒的,因此改革和管理也是永恒的。现实生活中不存在一劳永逸的改革和管理,也不存在万能的改革,两者必须相辅相成,共同促进企业的发展,而加强管理要以“人“为本,以企业文化为中心,重视人才资本工程、价值观工程和凝聚力工程的建设。     

Price Clustering Asymmetries in Limit Order Flows

We explore the relation between limit order price clustering and price efficiency. We find that executed sell limit orders cluster more frequently on round increments than buy limit orders and that this asymmetry in clustering is consistent with the well‐documented asymmetry in price response to marketable orders. In addition, we find that the degree of clustering is positively related to volatility and that asymmetry in clustering depends on whether stock prices are rising or falling—sell limit orders cluster more frequently as prices are rising, although buy limit orders cluster more as prices are declining. Our results indicate that predictable patterns in limit order pricing contribute to short‐run deviations from price efficiency.     

Conditions for the optimality of exponential smoothing forecast procedures

Exponential smoothing procedures, in particular those recommended byBrown [1962] are used extensively in many areas of economics, business and engineering. It is shown in this paper that:

1. Brown's forecasting procedures are optimal in terms of achieving minimum mean square error forecasts only if the underlying stochastic process is included in a limited subclass of ARIMA (p, d, q) processes. Hence, it is shown what assumptions are made when using these procedures.
2. The implication of point (i) is that the users ofBrown's procedures tacitly assume that the stochastic processes which occur in the real world are from the particular restricted subclass of ARIMA (p, d, q) processes. No reason can be found why these particular models should occur more frequently than others.
3. It is further shown that even if a stochastic process which would lead toBrown's model occurred, the actual methods used for making the forecasts are clumsy and much simpler procedures can be employed.
