This paper uses a stochastic frontier production function approach to measure technical efficiency in firms in Northern Ireland. Firm level census of production panel data were used to examine how efficiency in firms changed over the period 1973–1985. Once estimates of efficiency were made, the causes of inefficiency based on characteristics of firms were examined. The results indicate that efficiency in Northern Ireland has improved significantly over-time. The largest increases in efficiency were in indigenously owned firms. The results suggest that many Northern Ireland owned firms were 'catching-up' in terms of efficiency with foreign owned firms over the period.  相似文献

This paper estimates technical efficiency of Australian textile and clothing firms based on the data obtained from the Business Longitudinal Survey (BLS) conducted by the Australian Bureau of Statistics (ABS). Using a Cobb Douglas stochastic production frontier the paper examines firm level technical efficiency in the time varying inefficiency effect model with technical inefficiency effects assumed as an independently distributed truncated normal variable. Estimates of the production frontier revealed significant but small elasticities of labour and capital for textile and clothing firms, respectively, and a negative (but insignificant) Hicks neutral technical change for both. Estimated coefficients of the explanatory variables for inefficiency effects indicated that technical efficiency varied significantly according to firms' age, size, capital intensity, proportion of non-production to total workers and type of legal status. Predicted firm specific efficiency varied from 16 per cent to 95 per cent and mean efficiency ranged between 30 to 70 per cent. In view of these results policies have been suggested to improve technical efficiency of the firms as well as productivity growth of the sub sectors.  相似文献

Using firm-level data from the 1986 Census of Manufactures of Taiwan, we examine the links between technical efficiency and firm investments in technology and exports. Stochastic production frontier techniques are used to estimate the technical efficiency of firms by investments in technology as well as by export orientation. Our results indicate that accounting for firm investments in technology is critical in explaining the strong export-productivity link in the extant literature. For the group of large, high technology firms, the differences in the mean efficiencies between exporters and non-exporters are not significantly different than zero in all nine industries under study. However, for the large number of small firms that make no formal investments in technology. exporters are significantly closer to the production frontier than their counterparts that sell in the domestic market.  相似文献

This research investigates how legal sanctions prevailing under bankruptcy may impact on debt contracting and on investing decision. We model firms having the opportunity to engage (or not) faulty management. In case of default, the firms may escape costly bankruptcy by reaching a private agreement with the bank. We show that such renegotiation process may depend on the level of severity of bankruptcy law.Our approach helps in answering the following key questions: can bankruptcy costs always be internalized? Who benefits from accrued severity? Should the creditors accept a certain level of moral hazard from their debtors? Should bankruptcy law be extremely severe in order to ensure ex-ante efficiency? Does such severity depend on the financial environment?The model focuses on three equilibriums. The first equilibrium describes honest firms that choose the best investment project (ex-ante efficiency). Here, we show that bankruptcy costs can be avoided through private renegotiation (ex-post efficiency). Yet, the legislator cannot directly implement this equilibrium as it does not depend on the level of legal sanctions. A second equilibrium describes tricky firms turning to the less profitable and riskiest project. Here, default is still privately resolved: the occurrence of such equilibrium can be avoided owing to a minimal amount of legal sanctions that depend on the level of interest rate. Last, we consider firms that adopt mixed strategies regarding their investment policy. Here, two post-default bargains prevail (pooling or separating) and costly bankruptcy may occur.Simulations illustrate how the bank finally chooses between these equilibriums while the legal environment becomes more severe. For moderate levels of legal sanctions, banks may accept a certain level of faulty management, expecting to take advantage of bankruptcy punishment. An increase in sanctions, however, has a compelling effect on the companies towards honoring their commitments. Once the optimal equilibrium prevails, any additional increase in sanctions is ineffective as the players' strategies no longer depend on the legal environment. As a result, extreme severity is not required to ensure both ex-ante and ex-post efficiencies. Last, we find that a more severe bankruptcy law increases the protection of banks and may result in reduction of the contractual interest rate, which on the other hand benefits the debtors.  相似文献

Using a survey of over 4,000 firms in 21 transition economies, this paper investigates how legal extensiveness (law on the books) and legal effectiveness (law in practice) affect availability of bank finance. Our findings suggest that both law on the books and law in practice are important, but that they impact firms of different sizes differently. Small firms appear to be the most credit constrained in countries with weak creditor rights and with weak contract enforcement, while large firms are the most credit constrained in countries with weak courts and unclear and inconsistent laws pertaining to firms’ business operations.  相似文献

Using data obtained from firm interviews, the paper attempts to relate, statistically, economic performance with technology. The firms interviewed belong to four industries: food and beverages (ISIC 31), textiles and clothing (ISIC 32), wood and furniture (ISIC 33), and metalworking (ISIC 34). An aggregate, synthetic, technology variable was built using data on three components: transfer of technology channels, manpower technical skills, and technological efforts. The transfer channels component comprised three sub-components: number of licensing contracts, number of technical assistance agreements, and number of expatriate technical personnel. The skills component also included three sub-components: number of engineers, number of scientists, and number of middle level technical personnel employed. The technical efforts component was formed by the addition of two normalized sub-components: R&D expenditures and number of uses made of technical support services. All these variables were measured at the individual firm level. The paper explores first the relationship between technology (as defined above) and two potential explanatory variables: size of firm and foreign ownership. In a second statistical exercise, the technology variable is incorporated, with traditional factors of production, in a production function. In the last statistical exercise, firm performance indicators were related to technology. Based on the availability of reliable data, the two performance indicators selected were: output per worker and whether the firm exported part of its output or not. The possible incidence of sectoral (industry) effects was also taken into account. It could be concluded that the sample data used shows a statistically significant, though not very strong, effect of the technology variable on both, output and output per worker, and a somewhat stronger association with whether Zimbabwe's manufacturing firms export or not.  相似文献

This paper assesses the impact of Research and Development (R&D) efforts on production in the North and Centre-South of Italy by using a panel of 1,203 manufacturing firms over the period 1998–2003. The estimations are based on a nonlinear translog production function augmented by a measure of R&D spillovers. This measure combines the geographical distance between firms, the technological similarity within each pair of firms and the technical efficiency of each firm. The estimation method takes into account the endogeneity of regressors and the potential sample selection issue regarding firms’ decisions to invest in R&D. The two main results are as follows. Internal and external R&D have a lower impact in the Centre-South of Italy than in the rest of the country and they are weak substitutes whatever the area.  相似文献

中国服务业分行业生产率变迁及异质性考察   总被引:11,自引:0,他引:11  
本文采用全国两次经济普查后的修订数据,引入"技术不会遗忘"假定,运用序列DEA-Malmquist生产率指数法测算了1990—2010年中国服务业细分行业的全要素生产率(TFP)、技术进步、纯技术效率与规模效率增长率。结果表明,中国服务业总体及细分行业的TFP均处于上升通道,在上世纪90年代,服务业TFP增长的主导因素是技术效率改进,进入21世纪后,则主要是技术进步提高,且技术效率改进已开始由以纯技术效率为主转向以规模效率为主,但服务业发展的粗放型特征仍然明显。同时,中国服务业TFP增长表现出了较大的行业异质性;与工业(制造业)行业对比,服务业TFP增长是滞后的。2010年与1991年相比,TFP及技术效率增长的行业间异质程度有所下降,而技术进步却有进一步拉大的迹象。可能的内在机制是现代信息技术对不同服务业企业资源配置的异质影响,以及中国服务业体制改革的渐进式道路。  相似文献

By using panel data analysis across 368 water utilities in Mexico over the period 2010–2014, we find that small firms are more efficient than medium and large providers and that increasing production is associated with less efficiency. Billing, income collection and profitability are relevant factors to improve efficiency. Medium and large firms require to measure consumption by service with meters in order to increase efficiency, while small firms do not require it.  相似文献

如何提高投资者法律保护的执法效率是近年来财务学研究的热点问题,也是资本市场能否健康有序发展的一个关键因素。本文以2000—2010年沪深两市因违规受到处罚的A股上市公司为样本,从处罚公告前监管部门的查处及时性、处罚公告前后高管被迫离职、处罚公告时的市场反应三个维度,深入考察政治关联是否影响中小投资者法律保护的执法有效性。研究发现:(1)监管部门对政治关联公司的违规查处存在时滞效应,其惩处周期显著长于无政治关联公司;(2)在处罚公告前一年和后一年,政治关联公司高管的被迫离职率均显著低于无政治关联公司;(3)违规处罚公告时,政治关联公司的负向市场反应大于非政治关联公司,且这种现象主要表现在国有样本里。这说明,政治关联会削弱中小投资者法律保护的执法效率,且"违规查处及时性"和"高管变更"是两种重要的影响路径。  相似文献

This study uses data envelopment analysis to examine the liquidity and sales efficiency of the Food and Beverage listed firms in Athens Exchange in the period 2006–2012. The liquidity efficiency of the firms is higher than the sales efficiency but the results indicate that there are not statistical significant differences in the rankings estimated by the two models in each period. The Malmquist Productivity Index reveals that over the period of the study, firms have experienced an annual average increase in productivity of 0.5% (a slight progress). On examining the components of this productivity change, it becomes evident that firms have experienced an annual average of 2% increase in technology combined with a decrease in technical efficiency of –1.5%. The results indicate that 52.4% of the firms experienced productivity gains in the examined period, and this was mainly the result of technological gain rather than efficiency improvement. More than 90% of the firms in the sample shift the efficiency frontier and only 33.3% of the firms are catching up, improving their productivity by reducing inefficiency. Moreover, the empirical study reveals that the overall technical inefficiencies of the firms are primarily caused by pure technical inefficiencies rather than scale inefficiencies.  相似文献

This article examines the effects of agglomeration economies and industrial structure upon firm-level technical efficiency in the Indonesian manufacturing industry over the period 2004–2009. A stochastic production frontier and three channels of agglomeration economies consisting of specialization, diversity and competition are used. The empirical results show that the effects of specialization and diversity upon firm-level technical efficiency are positive and negative, respectively, indicating that specialization is more favourable than diversity for stimulating firms’ technical efficiency. Competition has a positive sign, showing that region with high levels of competition tend to be more conducive in accelerating firm-level technical efficiency. In terms of firm location, both dummy for urban region and industrial complex turn out to be positive, indicating that firms located in both areas are experienced higher technical efficiency. Both firm size and age also have positive effect upon technical efficiency.  相似文献

ABSTRACT ** :  In this paper, we test the extent to which producers' cooperatives can experience an increase in technical efficiency following a tightening of financial constraints. This hypothesis is tested on a sample of Italian conventional and cooperative firms for the wine production and processing sector, using frontier analysis. The results support the hypothesis that increasing financial pressure can affect positively the cooperatives efficiency.  相似文献

This paper examines the determinants of the total factor productivity (TFP) growth of Chinese renewable energy firms from 2011 to 2016, using a Bayesian stochastic frontier approach. Employing the “Bauer–Kumbhakar” decomposition method, the TFP growth is decomposed into the technology part and the market part. The empirical results reveal that the TFP improvement of Chinese renewable energy firms is mainly due to technical progress, followed by technical efficiency change. With regard to the market part, the misallocation of production factors has hindered the TFP growth. Our findings also indicate that only for large firms, the TFP growth can benefit from the scale economy effect. Compared with non‐state‐owned firms, state‐owned firms suffer much lower allocative efficiency.  相似文献

This article analyzes the effects of intrafirm bargaining on the formation of firms in an economy with imperfect capital markets and contracting constraints. In equilibrium, wealth inequality induces a heterogeneous distribution of firm sizes, allowing for firms both too small and too large in terms of technical efficiency. The findings connect well to empirical facts such as the missing middle of firm‐size distributions in developing countries. The model can encompass a nonmonotonic relationship between aggregate output and inequality. It turns out that an inflow of capital may indeed decrease output in absolute terms.  相似文献

Using data for a large sample of manufacturing and service sectors in 14 EU countries, this paper shows that the value added and TFP growth rate differential between high and low human capital intensive industries is greater in countries with low than countries with high levels of employment protection legislation. We also find that such negative effect of EPL is slightly stronger for countries near the technology frontier, in the manufacturing sector and after the 1990s. We interpret these results suggesting that technology adoption depends on the skill level of the workforce and on the capacity of firms to adjust employment as technology changes: therefore, firing costs have a stronger impact in sectors where technical change is more skill-biased and technology adoption more important.  相似文献

A stochastic frontier production function is used to estimate the effect of partial and gradual reforms in the 1980’s in each of seven state-owned manufacturing industries. Reform-induced gains in technical efficiency were significant in all sample industries although not always substantial enough to motivate industry-wide productivity growth. The bonus system had speedy and impressive efficiency effects, but there is no consistent evidence on the effectiveness of other reform measures, including greater output autonomy, partial exposure to market influences, and the possibility of dismissals for malfeasance. Equalization of marginal factor returns across firms was observed in some industries, which may be considered as evidence of improved allocative efficiency in response to the reforms.  相似文献

This article examines the technical efficiency of museums based upon data derived from a questionnaire survey of South West England. A stochastic frontier production function is estimated with output measured in terms of visitor numbers. The Cobb-Douglas function is shown to be the best representation of the production function. Average levels of efficiency are estimated to be fairly low at 45.5% with wide variations across museums. The results indicate that high levels of public funding and voluntary activity have a significantly negative impact on technical efficiency. It is argued that further research is needed to develop more sophisticated measures of the output of cultural industries and understand the economic importance of volunteers.  相似文献
