We used the Kauffman Firm Survey of ventures founded in the year 2004 to identify overconfident (OC) entrepreneurs and found, contrary to the existing literature, that the hazard ratio for these entrepreneurs was lower than the corresponding value for their non-OC peers. We categorized an entrepreneur as OC if he or she believed that his or her firm enjoys a competitive advantage over its industry peers, while simultaneously underperforming relative to the industry in terms of average initial ROA. Specifically, we looked at the average ROA during the years 2004–2007 and compared it to the industry median. In addition to our hazard findings, we discovered that these OC entrepreneurs, while starting with lower initial ROA levels relative to their industry peers, may have enjoyed slightly better movement in ROA over the intervening years. Our results are explained in the context of the psychological literature on optimism.  相似文献

This paper provides new empirical evidence on the effects of mergers and acquisitions (M&As) on the shape of the firm size distribution, by using data of the population of manufacturing firms in the Netherlands. Our analysis shows that M&As do not affect the size distribution when we consider the entire population of firms. When we focus on the firms involved in an M&A event, we observe a shift of the firm size distribution towards larger sizes. Firm size distribution becomes more concentrated around the mean, less skewed to the right hand side, and thinner at the tails as a whole. The shift toward higher sizes due to M&A is not uniform but affects firms of different sizes in different ways. While the number of firms in the lower tail decreased, the number of firms in the central size classes increased substantially and outweighed the increase in the number (and mean size) of firms in the upper tail of the distribution (consequently the overall market concentration measured by the Herfindahl index declines). M&As lead to a departure from log-normality of the firm size distribution, suggesting that external growth does not follow Gibrat’s law. Our counterfactual analysis highlights that only internal growth does not affect the shape of the size distribution of firms. On the contrary, it suggests that the change in the size distribution is almost entirely due to the external growth of the firms.

The diffusion of agricultural innovations is rarely rapid. As a result, adoption decisions over time are very likely to be influenced by changes in generic factors such as the price of complementary inputs and environmental conditions. Despite this, the vast majority of studies aiming to explain innovation adoption are limited to cross-sectional data and analysis techniques that cannot accommodate time-dependent variables. This study departs from these attempts by using a duration analysis technique to investigate the significance of time-dependent economic and environmental variables, along with cross-sectional variables such as technology-specific perceptions, on the adoption of soil-conserving cropping practices by grain growers in southern Australia over the period 1983–2003. Of particular interest is the possible trade-off faced by farmers where adoption of no-tillage cropping technology can lead to greater herbicide reliance and subsequently unsustainable weed management due to high risks of herbicide resistance. Results show that factors affecting the cost-effectiveness of herbicides are important in the adoption of the erosion-reducing cropping systems. Several factors relating to the availability and use of technical information are also shown to be influential. The duration analysis approach allowed changes in time-dependent variables, including the fall in the price of the herbicide glyphosate, to be identified as determinants of the timing of no-till adoption.  相似文献

A unique data set is used to provide a detailed examination of the survival of newly established manufacturing firms in north-east England. Using data on 781 firms established between 1973 and 2001, log-logistic hazard models are estimated separately for (i) micro-enterprises and (ii) small and medium establishments (SMEs). Both micro-enterprises and SMEs show clear evidence of positive duration dependence, followed by negative duration dependence. We find the two firm types are differentially affected by firm-specific and macro-economic variables. Increases in initial plant size impact negatively on micro-enterprise survival and positively on SME survival.  相似文献

The paper empirically investigates the issue of financial constraintsto investment, focusing on its relationship with innovationactivities. The study is based on the analysis of a cross-industriespanel of 804 Italian companies, observed through the years 1995–2000.The main objective of the study is to highlight whether thereare financial determinants underlying the strong bias of patentingactivity towards larger companies in the Italian economy. Byapplying a dynamic panel analysis, we found that only the firmsshowing lower financial constraints are able to keep a sustainedpatenting profile through time. Our evidence suggests the existenceof an imperfect capital market in the Italian economy, particularlyin the case of medium-sized companies, which tend to delay inefficientlythe start of in-house R&D activities.  相似文献

Adjusting product line length is one major strategy that firms employ to sustain their market position in competitive environments. This study extends extant literature on product line length by adding empirical results on the relationship between competitive intensity and product line length, and by examining the performance of firms that follow the suggested product line strategies. The analysis of data on 1849 printer products introduced by 342 manufacturers from 1983 to 2002 shows an inverted U-shaped relationship between competitive intensity and product line length, and firms following this pattern have a significantly lower hazard ratio of exit. These results confirm those discussed in the previous literature and provide evidence of the positive impacts of following such product strategies on firm survival.  相似文献

One reason why firms exist, this paper argues, is because they are suitable organizations within which cooperative production systems based on human social predispositions can evolve. In addition, we show how an entrepreneur, given these predispositions, can shape human behavior within a firm. To illustrate these processes, we will present a model that depicts how the biased transmission of cultural contents via social learning processes within the firm influence employees’ behavior and the performance of the firm. These biases can be traced back to evolved social predispositions. Humans lived in tribal scale social systems based on significant amounts of intra- and even intergroup cooperation for tens if not a few hundred thousand years before the first complex societies arose. Firms rest upon the social psychology originally evolved for tribal life. We also relate our conclusions to empirical evidence on the performance and size of different kinds of organizations. Modern organizations have functions rather different from ancient tribes, leading to friction between our social predispositions and organization goals. Firms that manage to reduce this friction will tend to function better.  相似文献

ABSTRACT

This paper applies a linear Bayesian regression model to study the effects of economic policy uncertainty (EPU) and Chief Executive Officer (CEO) characteristics on firm Research and Development (R&D) expenditure. We specifically analysed data from 1,163 Chinese companies listed as A-shares from 2008–2016. EPU is believed to curtail firm investments as it causes unexpected market conditions. Yet, our findings obtained with Bayesian analysis show a positive relationship between EPU and firm R&D expenditure. Specifically, we found that some CEO attributes (e.g., age, tenure and marketing/sales experience) led to a negative relationship between EPU and firm R&D expenditure, whereas other attributes (e.g., education, overseas study/work experience, product R&D experience, and process engineering experience) lead to a positive relationship. Our findings provide nuanced insights into how different CEO characteristics influence firms’ R&D expenditure in a context of uncertainty.  相似文献

The paper analyzes the effects of the properties of firms' knowledge base on the survival likelihood of firms. Drawing upon the analysis of the patterns of co-occurrence of technological classes in patent applications, we derive the coherence, variety and cognitive distance indexes, accounting respectively for technological complementarity, differentiation and dissimilarity in the firms' patent portfolios. The results of our analysis are in line with the previous literature, showing that innovation enhances the survival likelihood of firms. In addition, we show that the search strategies at work in the development of firms' knowledge base matter in reducing the likelihood of a failure event. Knowledge coherence and variety appear to be positively related to firms' survival, while cognitive distance exerts a negative effect. We conclude that firms able to exploit the accumulated technological competences have more chances to be successful in competing durably in the market arena, and derive some policy implications concerning the role of public intervention in the orientation of search efforts in local contexts.  相似文献

This paper contributes to understanding the determinants of patent value. By drawing on a real options approach, we develop a theoretical model of patent value, which explicitly considers the uncertainty about future value. On this basis, we rely on Monte Carlo simulations with data from a case study in a large chemical firm to estimate patent value according to our model. In the simulation analyses, we compare an R&D project with patent protection and the same project without patent protection. The difference of the values of the two projects is the surplus in profit that may be expected from having a patent covering the project. This surplus is regarded as the value that is directly attributable to the patent. The results of the simulation analyses indicate that the development costs and expected net cash flows of a patent-protected project are higher than of an unpatented project. The higher net cash flows outgrow the increased development costs, and patent value is positive. However, this value is smaller than the overall project value of the patent-protected R&D project.  相似文献

Emerging technological fields are affected by developments in their broader context. This article proposes a differentiation of context structures as a crucial step in the analysis of technological innovation systems. A thorough context analysis, so the argument, is essential for understanding the pace and direction of technology development and the prospects of an emerging technological innovation system. Empirical insights are provided for Bio-SNG, a technology in an early stage of development. The article discusses the conditions under which actors from different sectors (forestry, wood industry, and energy supply) may play a role in the emerging field. It is shown that Bio-SNG is likely to become a victim of the recent boom in wood-to-energy technologies that has favored investments in more mature but technologically inferior alternatives. The case provides lessons for policy making as it highlights how effective support schemes might foster a lock-in into technologies that are readily available.  相似文献

This article tries to identify the determinants of housing price volatility and to examine the dynamic effects of these determinants on volatility using quarterly data for Canada. The Generalized Autoregressive Conditional Heteroskedastic (GARCH) and the Vector Autoregressive (VAR) models have been employed to analyse possible time variation of the housing price volatility and the interactions between the volatility and the key macroeconomic variables. We find the evidence of time varying housing price volatility for Canada. Our VAR, Granger causality and variance decomposition (VDC) analyses demonstrate that housing price volatility is affected significantly by gross domestic product (GDP) growth rate, housing price appreciation rate and inflation. On the other hand, volatility affects GDP growth rate, housing price appreciation and volatility itself. The impulse response analysis reveals the asymmetric of the positive and negative shocks. The findings of this article have important implications, particularly for those seeking to develop derivatives for housing market prices.  相似文献

Two important problems exist in cross-country growth studies: outliers and model uncertainty. Employing Sala-i-Martin’s (1997a,b) data set, we first use robust estimation and analyze to what extent outliers influence OLS regressions. We then use both OLS and robust estimation techniques in applying the Extreme Bounds Analysis (EBA) to deal with the problem of model uncertainty. We find that the use of robust estimation affects the list of variables that are significant determinants of economic growth. Also the magnitude of the impact of these variables differs sometimes under the various approaches.First version received: March 2003 / Final version received: June 2004We like to thank two referees for their very helpful comments on a previous version of this paper.

This paper studies the firm’s decisions on in-house R&D and its procurement from outside through commissioned R&D, joint R&D, and technology acquisitions (i.e., licensing-in). Using the data about 14,000 manufacturing firms in Japan, we estimate a modified double-hurdle model in which the first hurdle determines whether the firm should perform any R&D at all and the second hurdle determines whether (and how much) it should perform each mode of procured R&D. The results generally support the two major theories—the transaction cost theory and the capability theory. The estimated positive effects of firm size, in-house R&D intensity, diversification, and vertical integration support the hypothesis that capability is needed for procured R&D, while the estimated positive effect of the index of appropriability by patents supports the hypothesis that this appropriability reduces transaction costs. In addition, we found that information flow from scientific sources and that from transaction-based sources affect the three modes of procured R&D differently.  相似文献

This paper develops an inter-industry model of inward investment, using a fixed effects approach. This demonstrates that when inward investment is investigated in such a framework, previous findings, relating to the specification of measures of location advantage and ownership advantages no longer hold. This also shows that there are some industries that have attracted significant inward investment over time, and continue to do so, while others are noticeably less successful. Reasons for this, and potential policy measures are briefly discussed.  相似文献

This article examines the dynamic relationships among output, carbon emission and renewable energy generation of India and China during the period 1972 to 2011 using a multivariate vector error correction model (VECM). The results for India reveal unidirectional short-run causality from carbon emission to renewable energy generation and from renewable energy generation to output, whereas in the long run, the variables have bidirectional causality. Causalities in China give a rather different scenario, with a short-run unidirectional causality from output to renewable energy and from carbon emission to renewable energy generation. In the long run, for China, unidirectional causality is found from output to renewable energy generation, while bidirectional causality is found between carbon emission and renewable energy generation.  相似文献

Normally, privatisation is seen as beneficial. This paper considers the case of Serbia – a latecomer in the matter – where privatisation was partly a result of exogenous pressures and where the process has been deemed a failure. In Serbia, a sizeable number of privatised firms were bought by bureaucrats and politicians and all firms were subjected to a period of supervision. We argue that the design of this process allowed rent-seekers to conserve their privileges through asset-stripping, which explains the failure. In order to do so, we perform an empirical analysis of the determinants of liquidation, merger and bankruptcy of privatised firms from 2002 to 2015. We construct a novel data set from primary sources, free of the ‘survivorship bias’ and containing proxies for various types of owners, indirect signs of asset-stripping strategy and a broad range of controls. Our results indicate that firms owned by politicians faced significantly higher risks of bankruptcy, especially after the end of supervision.  相似文献

Summary. Iterated function systems make up an interesting class of stochastic processes which are useful for many types of stochastic modeling. In this paper we review and slightly generalize a contractivity condition guaranteeing uniqueness of invariant measures. Also, we examine how the invariant measure, and thus also the asymptotic behavior, of such a process is affected by perturbations of the defining functions and probabilities.Received: 15 September 2002, Revised: 29 October 2002, JEL Classification Numbers: C62, O41.I would like to thank Professor Göran Högnäs for his support. I am also greatly indebted to the Finnish Graduate School in Stochastics for my financial support and I would like to thank the anonymous referee for the helpful comments.  相似文献
