Determinants of Entry in Turkish Manufacturing Industries

The entry of new firms into markets plays an important role in efficient resource allocation and evolution for long term economic growth. Employing dynamic panel data techniques, this paper investigates entry behavior in 66 four-digit Turkish manufacturing industries for the 1993–1999 period. The results of this paper suggest that potential entrants observe the market before the entry takes place; entry is, in general, a follow-up process; and incumbent firms seem to collude to prevent entry in Turkish manufacturing industries. In addition, the real interest rate appears to be a very important determinant of entry decision.     

Export Entry,Export Exit and Productivity in German Manufacturing Industries

This paper contributes to the flourishing literature on exports and productivity by using a unique newly available panel of exporting establishments from the manufacturing sector of Germany from 1995 to 2004 to test three hypotheses motivated by a theoretical model by Hopenhayn (Econometrica 1992): (H1) Firms that stop exporting in year t were in t?1 less productive than firms that continue to export in t. (H2) Firms that start to export in year t are less productive than firms that export both in year t?1 and in year t. (H3) Firms from a cohort of export starters that still export in the last year of the panel were more productive in the start year than firms from the same cohort that stopped exporting in between. While results for West Germany support all three hypotheses, this is only the case for (H1) and (H2) in East Germany.     

Does Size Matter in Firm Performance? Evidence from US Public Firms

This paper reexamines the determinants of firm performance and, in particular, the role that firm size plays in profitability. A fixed‐effects dynamic panel data model for over 7,000 US publicly‐held firms during the period 1987–2006 provides evidence that profit rates are positively correlated with firm size in a non‐linear manner, holding an array of firm‐ and industry‐specific characteristics constant. In addition, industry‐specific fixed effects play a negligible role in the presence of firm‐specific fixed effects.     

Firm exits as a determinant of new entry: Is there evidence of local creative destruction?

This study posits that a local process of creative destruction provides an impetus to regional industrial renewal. We argue that exits of older firms release resources that stimulate local entry. New entrants add value to these resources by redeploying them in more productive uses. We test our hypotheses with a unique longitudinal database encompassing the entry and exit of Canadian manufacturing enterprises. We find that exits of old firms increase entry and that on average new entrants are more productive. Persistent high local rates of exit, however, deter entry.     

中国对外反倾销措施的产业救济效应评估——基于动态面板数据模型的微观计量分析

本文选取1997年3月-2009年6月中国对外反倾销案例的涉案产品和国内相关进口竞争性产业数据,构建动态面板数据模型定量评估中国对外反倾销措施对进口竞争性产业的救济效果。结果表明,虽然反倾销措施对中国相关进口竞争性产业具有显著的救济作用,但是贸易转移效应和上下游产业继发性损害效应的存在会在一定程度上削弱上述产业救济效果。在此基础上,本文提出了中国对相关国外进口品实施反倾销的路径选择与政策建议。     

Corporate Demography and Empirical Industrial Organization: A Critical Appraisal

The emerging field of corporate demography views corporations and industries in a similar way to human or animal individuals and groups. In spite of a surprisingly large overlap of subject matter with economics, corporate demography is not well-known by, nor easily accessible to economists. An extremely useful recent book, The Demography of Corporations and Industries, by Glenn R. Carroll and Michael T. Hannan (2000) should change that. This review essay critically examines corporate demography from an economic viewpoint. The very different view of competition in corporate demography gets particular attention.     

Business Survival and the Decision to Exit

The decision to exit is examined for a cohort of over 12,000 plants established in 1976. Using a longitudinal data base, the performance of the establishments is analysed over the subsequent 10 years. The empirical evidence suggests that start-up size, ownership status, and the industry environment affect the likelihood of a start -up subsequently exiting. Plants with more employees during the start -up year are found to have a lower likelihood of exit than do smaller plants. Similarly, establishnwnts which are independent are found to have a lower likelihood of exit within the following years than do newly created establishments belonging to a multi-plant firm. However, the determinants of exit apparently vary along with the age of the establishment. Innovative activity is found to raise the likelihood of establishment exit in the short run but lower it in the longer run.     

地方公共物品供给对FDI影响的实证分析

以蒂布特模型的用脚投票理论为基础,利用中国30个省市1997～2005年的Panel Data建立Panel Data模型,实证分析各地区的地方公共物品供给对吸引FDI的影响,结果表明,地方公共物品的供给与FDI的吸引呈显著正相关,各地区公共物品供给差异是FDI区域分布差异的一个重要原因.     

消费信贷与经济增长关系的实证研究——基于我国省级面板数据分析

近几年来,消费信贷呈爆发式增长,明确消费信贷与经济增长之间的关系,对于如何提高经济的快速发展具有重大的意义。文中使用2007-2018年我国31个省级面板数据,构建短面板数据模型,研究消费信贷与经济增长之间的关系。研究结果表明:消费信贷与经济增长之间的线性关系并不显著,二者之间存在着非线性关系,且消费信贷对经济增长具有明显的拉动作用。

The impact of early imprinting on the evolution of new venture networks

Given the argued importance of networks to new ventures, this paper is intended to fill a noted gap in the literature pertaining to the factors that influence the evolution of new ventures' alliance networks. Drawing on the imprinting literature, we propose that one has to look beyond the first partner per se, and instead focus on the extant relationships the initial partner has with other firms. More specifically, we argue and find that the network size and centrality of a new venture's initial alliance partner influence the subsequent size of the new venture's network.     

未被观测经济与居民收入不平等——基于中国省级面板数据的实证研究

未被观测经济（NOE）对经济发展具有诸多影响,但对居民收入不平等的影响尚未引起足够重视。文章基于动态均衡解的劳动报酬模型得到,随着NOE规模扩大,收入不平等程度（即劳动者从事NOE部门的报酬与从事可观测部门的报酬之差）呈现单调递增的变化过程,但边际变化率先增后减。当考虑劳动者决策的随机动态调整因素时,NOE规模与收入不平等之间存在高低两个动态变化均衡点。在该模型基础上,基于2000-2010年中国省级面板数据,证实了NOE规模与居民收入不平等之间存在显著正向影响关系,人力资本水平、市场化程度和腐败水平也与居民收入不平等呈正向影响关系,而城市化水平则呈较显著的负向影响关系。基于实证结果,提出了相关的政策建议,并对未来研究方向进行展望。     

Hit and Run or Sit and Wait? Contestability Revisited in a Price-Comparison Site-Mediated Market

The price-comparison site, with its (near-)zero sunk costs of entry, would appear to approximate the “almost perfectly contestable market” envisaged by the contestability theorists where “hit-and-run” entry was conjectured to constrain sellers to zero-profit outcomes. We investigate hit and run using a unique unbalanced panel of 295 digital-camera markets mediated by NexTag.com. We find, however, in line with Farrell (1986a)’s prediction, a bifurcation of strategies with low reputation/smaller participants favouring a hit-and-run strategy involving lower entry prices and shorter forays into the market than their high reputation/larger rivals. Furthermore, the former entrants induce a much larger price response from low-reputation incumbents, reflecting the more intense rivalry for the price-sensitive consumers willing to eschew retailer reputations.     

探究第三产业占比对人力资本积累的影响--基于我国2005年-2011年省级面板数据的实证检验

我国正处于产业结构转型的关键时期,一二产业逐渐向第三产业转移。以往研究大多落脚于人力资本对产业结构的影响,而忽略了由于产业转型带来的对高技术人才的需求推动了人力资本的积累。作者认为,产业结构的优化将有助于人力资本的积累,同时,文化消费、教育投入等因素也会影响到人力资本。本文使用2005-2011年,我国31个省份的面板数据,建立了多元线性回归模型,运用工具变量的方法,以金融发展状况作为第三产业占比的工具变量,进行实证研究。在控制了年份和省份的固定效应后,我们发现第三产业占比对人均人力资本有显著的正向影响,产业结构向第三产业转移有利于人力资本积累。在此基础上,我们提出了若干建议来推动产业结构的优化。     

外国直接投资与我国技术创新研究
