Entry and barriers to entry in emerging markets

This note briefly introduces the symposium on entry and entry barriers in emerging markets edited by Nauro Campos and Saul Estrin. The symposium contains four inter-related case studies focusing in depth on the relationship between entry of new firms and institutional arrangements in four major emerging markets: Brazil, China, India and Russia. We find that entry rates are not necessarily low in emerging markets, and that institutional quality is a complex and “fuzzy” notion so that its impact on the entry process is not straightforward.

New Firms' Survival and Market Turbulence: New Evidence from Spain

The availability of longitudinal data for individual firms has allowed the improvementof the existing knowledge on market structure dynamics. We present additional evidence through the analysis of a cohort of Spanish manufacturing firms. Our results confirm some basic empirical findings obtained in studies for other countries. According to the behavior of the cohort we study, Gibrat's Law does not hold for new entrants. Patterns of market turbulence vary considerably according to the type of industry. The behavior of new firms seems to fit the learning model. The estimation of a hazard function demonstrates that the main regularities affecting the likelihood of survival of young firms are quite similar in different types of countries.     

Multinational Companies and Entrant Start-up Size: Evidence from Quantile Regressions

This paper analyses the impact of foreign multinationals on the start-up size ofdomestic entrants in Irish manufacturing industries. We use the regression quantileestimator, which allows us to take account of the heterogeneity of entrants' start-upsize. Estimation results show that the presence of foreign multinationals in a sectorimpacts negatively on the start-up size of domestic entrants of all sizes in modernsectors and on the start-up size of large domestic entrants in traditional sectors. Thisnegative effect may be attributed to competition of domestic plants with foreignmultinationals and other domestic plants in the final goods and/or the intermediategoods market.     

跳频通信中一种结合干扰预处理的平方定时同步算法

为了提高跳频通信中定时同步算法的准确性,设计了一种结合干扰预处理的跳频信号定时同步算法。首先对解跳后信号在时域完成基于能量的自适应门限的干扰检测,并根据检测结果将受干扰信号进行置零预处理;其次对预处理后的信号采用平方法进行定时误差估计;最后根据估计结果内插完成定时恢复。结果表明,提出的改进算法选取长度为200跳的符号,在干扰相对带宽为30%、干信比为10 dB、信噪比为5 dB、时钟稳定度为1×10^-6的条件下,进行干扰预处理后定时,归一化定时误差的方差为0.000 75,满足跳频系统解调性能损失小于0.5 dB的要求。设计方法提高了干扰条件下平方法定时的准确性,在跳频通信抗干扰应用中有一定的参考价值。     

基金绩效评估模型及其在我国的应用

由于国外较为流行的整体绩效评估指标目前在我国开放式基金业绩评估中处于失效状况，而传统的收益率指标又由于未考虑风险因素而存在缺陷，选择何种适合我国特点的评估模型尚有大量的问题急待解决，对国外广泛应用的证券投资基金绩效评估模型进行分析，发现综合利用这些模型对我国开放式基金绩效进行评估尚须时日。

The role of firm resources and organizational attributes in determining entry timing: a cross-industry study

We investigate the factors that influence the timing of entry of firms into new industries based on new technology. Consistent with previous research, it is hypothesized that firm resources and organizational attributes influence entry timing. Unlike previous research, there is specific consideration of how industry setting—specifically, the extent to which it offers first mover advantages—influences the ability to predict timing of entry. The ability to explain entry timing differed across industries, with success occurring in the industry with strong first mover advantages. Two categories of resources, technological and marketing, were found to be associated with early entry. The organizational attributes that influenced early entry were commitment to a threatened market and (surprisingly) greater size. © 1998 John Wiley & Sons, Ltd.     

高大平房仓仓顶定时自动喷淋实仓试验

在高大平房仓仓顶安装了定时自动喷淋系统,进行夏季喷淋试验,利用水的蒸腾作用带走仓顶积热,减弱热传导,从而降低仓温、控制粮温.结果表明：实施仓顶定时自动喷淋在夏季高温季节能降低仓房夹层温度3～7℃,降低仓温2～3℃,有效控制表层粮温的升高,从而延缓粮食品质劣变速度.与传统的喷淋系统相比,节省人工和资源成本,达到降本增效的目的.
