Trade liberalization and technical efficiency in the Indonesian chemicals industry

This article examines the impact of trade reform on technical efficiency on the Indonesian chemicals industry using firm-level panel data. The effects of trade reform on technical efficiency are analysed using a stochastic frontier approach. Two variables represent trade reform in this model: effective rate of protection (ERP) and import ratio (IMP). The findings of the present study suggest that both trade reform variables have significant effects on technical efficiency. The coefficient of ERP has a positive sign and is statistically significant, which means that an increase in ERP increases the inefficiency (or decreases the technical efficiency) of firms in the chemicals industry. The coefficient of IMP is negative and statistically significant, which represents the negative impact of IMP on technical inefficiency (or positive on technical efficiency). Thus, trade reform, a reduction in ERP or an increase in IMP, has an unambiguously positive effect on technical efficiency in the Indonesian chemicals industry.     

Elasticity of substitution and technical efficiency: evidence from the US electricity generation

ABSTRACT

The implications of national or regional energy policies for technical efficiency and environmental outcomes in electricity generation depend on fossil fuel input substitution. This study uses state level data to examine fossil fuel (coal and natural gas) substitution in electricity generation under increased availability of natural gas in the United States. We observe that changes in elasticities of substitution from pre-2009 to post-2009 differ across states suggesting that the effects of increased availability of inexpensive natural gas on electricity generation have been spatially heterogeneous. We rely on the observed heterogeneity to assess the effects of fossil fuel input substitution on technical efficiency and CO₂ emissions. The results reveal that state level elasticity of substitution between natural gas and coal has a positive effect on technical efficiency and a negative effect on CO₂ emissions. Therefore, future policy design and analyses should reflect the implications for regional elasticities of fossil fuel substitution and associated environmental outcomes.     

Economic openness and technical efficiency: A case study of Chinese manufacturing industries

This paper presents a study of the technical efficiency of industries in a transitional economy: China. Using data for 28 manufacturing industries across 29 provinces and the Data Envelopment Analysis approach, the technical efficiency of each industry is measured and compared across regions and provinces. The determinants of differential technical efficiency performance are analysed, with a particular focus on the impact of trade orientation and foreign investment. Trade openness is found generally to have a positive effect on technical efficiency.     

Effect of public subsidies on farm technical efficiency: a meta-analysis of empirical results

Investigating the impact of public subsidies on farm technical efficiency is becoming a critical issue in applied agricultural policy analysis. This article presents a meta-analysis of empirical results on this issue, based on data gathered from a systematic literature review. We find that, in the empirical literature, subsidies are commonly negatively associated with farm technical efficiency. Meta-regression estimation results show that the direction (significantly negative, significantly positive or non-significant) of the observed effects is sensitive to the way subsidies are modelled in the empirical studies.     

Analyses of technical efficiency using SDF and DEA models: evidence from Nepalese agriculture

Alleviation of poverty is a central issue in Nepal. Given the limited stock of land and the infant/unorganized manufacturing sector, increased demand for food has to be satisfied by improving production efficiency. This article examines how this could be achieved. Stochastic distance function and data envelopment analysis models identify the existence of a high degree of technical inefficiency in Nepalese agriculture, suggesting that there is a substantial prospect of increasing agricultural productivity using the existing level of inputs and resources more efficiently. Among the three farm sizes in the data set, medium size farmers achieve a higher technical efficiency than large and small farm sizes, suggesting that productive efficiency can be increased with the encouragement of creating medium size holdings. The observed decreasing returns to scale also implies that productivity gains could be achieved by breaking up of large farms into small family farms. The technical inefficiency model suggests the potential for shifting the production frontier upwards by providing ownership of land, increasing farmers’ education and knowledge, and increasing land quality, including irrigation facilities.     

The impact of trade openness on technical efficiency in the agricultural sector of the European Union

The aim of this study is to analyse the impact of trade openness on technical efficiency of the European Union’s (EU) agricultural sector. There are no systematic theories linking trade policy to technical efficiency; hence, the relation between trade liberalization and technical efficiency is fundamentally ambiguous. Stochastic frontier analysis is used to model the relationship between EU’s production resources and agricultural output, as well as the importance of trade openness on technical efficiency of a country. The data for 16 of the 28 EU members were available for the period 1980–2007 including land, capital, fertilizer, labour, agricultural GDP, foreign direct investments (FDI), exports and import data. Results indicate that trade openness has an immediate, negative impact on efficiency in the EU agricultural sector. Over time, however, trade openness does increase efficiency. The FDI outflows increase efficiency. This suggests that an initial reduction in capital supply forces EU nations to utilize other factor inputs more efficiently. However, there is the unexamined potential that over time the depletion of capital results in a decrease in efficiency. Finally, formerly communist member-countries of the EU are found to have the lowest technical efficiency scores whereas Southern European nations have the highest efficiency.

The effects of agglomeration economies on technical efficiency of manufacturing firms: evidence from Indonesia

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.     

The effect of land tenure governance on technical efficiency: evidence from three provinces in eastern China

This study aims to identify the mechanisms through which land tenure governance affects the technical efficiency of grain production in an integrated framework and to examine the impacts of the public governance, village self-governance, and relational governance of land tenure on the technical efficiency of contracted land and rented-in land. Farm-level survey data collected from Liaoning, Jiangxi, and Jiangsu provinces covering the years of 2014 and 2015 is used for the empirical analysis. The findings indicate that (i) public governance associated with land certification significantly increases the technical efficiency of grain production; (ii) village self-governance and administrative land reallocations can serve as substitutes for the land rental market in optimizing the distribution of land resources and improving technical efficiency; and (iii) compared to multi-year transfer contracts, both annual and open-ended transfer contracts have negative impacts on technical efficiency.     

环境约束下中国与世界主要国家技术效率和生产率的测度与比较

运用含非期望产出的超效率SBM(slack based measure)模型和GML(global Malmquist-Luenberger)指数,对中国与世界主要国家1991—2016年的分别在考虑和不考虑环境约束下的技术效率和全要素生产率进行测度与比较。研究发现,不考虑环境约束的测度结果忽略了一国发展所造成的污染损失,导致技术效率与生产率被高估;中国的技术效率在考虑环境因素后显著下降,总效率排名从样本中的第16位下降至第40位。时间趋势上,中国的环境效率与技术效率的差距呈现先扩大后缩小,且近年来有逐渐趋同的态势;动态视角上,不考虑环境约束时中国的全要素生产率变化总体呈现增长趋势,但在考虑环境因素后中国的环境全要素生产率转变为下降趋势,这其中,技术进步的下降是影响环境全要素生产率变化的主要因素。     

Regional technical efficiency and technology gaps in rural China: evidence from CHIP surveys

This paper uses household-level datasets called Chinese Household Income Project (CHIP) surveys to investigate the regional technical efficiency, technology gap, and their determinants in rural China. A metafrontier production function approach is employed to fit the values of the technical efficiency and the technology gap ratio of rural households in six regions of China. The findings indicate that the technical efficiency improved remarkably from 1988 to 2002, but the technology gap ratio among regions changed slightly in the same period. The findings also show a negative relationship between the technology gap ratio and the regional technical efficiency for all regions except the northwest that has the lowest value of both the technical efficiency and the technology gap ratio. Next, the Tobit model is employed to discern the sources of efficiency and technology gaps. The results show that quality of agricultural labor, agricultural infrastructure, natural conditions, and farmer's political status have significant effects on farms' technical efficiency and technology gap ratio.     

Technical efficiency and returns to scale in Austrian commercial banking: 1987–1991

In a pooled time-series cross-section study covering the period 1987–1991, the technical efficiency of Austrian all-purpose banks is analysed. The sample covers banks of all size classes, among them the largest 18 banks as well as some of the very small banks. The empirical results show that local banks and nationwide operating banks are technically most efficient while regional banks are least efficient. Moreover, it can be shown that the technical efficiency of nationwide operating banks improved substantially in the period analysed relative to that of local and regional banks.I wish to thank an anonymous referee for his helpful comments.

Predictability of sustainable investments and the role of uncertainty: evidence from a non-parametric causality-in-quantiles test

In this article, we examine sustainable investments returns predictability based on the U.S. Dow Jones Sustainability Index (DJSI) and a wide set of uncertainty and financial distress indicators for the period 2002:01–2014:12. To this end, we employ a novel non-parametric causality-in-quantile approach that captures non-linearities in returns distribution. Based on our findings we conclude that the aggregate economic policy uncertainty (EPU) indicator and some components have predictive ability for real returns of the U.S. sustainable investments index. Moreover, if we split our sample to before and after the global financial crisis our results suggest that predictors carry causal information for real returns only in the after-crisis period. Finally, some marginal evidence of predictability from sovereign debt is also observed at the lower and upper ends of the conditional distribution of the real returns of sustainable investments. Our results might entail policy implications for investors and market authorities.     

农村信用社利率定价模型实证分析

利率市场化改革的核心是建立科学合理的利率定价制度。目前,多数中小金融机构特别是农村信用社,贷款定价模式比较简单粗糙,在实际执行过程中广泛存在＂一刀切＂的现象。科学合理的利率定价模型不仅要涵盖银行资金成本、风险、目标利润等,还需要考虑贷款人的对利率的承受能力并有较强的可操作性。

A flexible time-varying specification of the technical inefficiency effects model

The temporal pattern of technical efficiency in the technical inefficiency effects model, as modeled by Battese and Coelli (Empir Econ 20:325–332, 1995), is rather restrictive. Specifically, it a priori imposes a common pattern upon all firms in the sample, which in addition is monotonic over time. Obviously this is an undesirable implication of the model especially when there is evidence of strong firm heterogeneity and/or a long time span. To overcome this shortcoming, the present paper incorporates the Cornwell et al. (J Econom 46:185–200, 1990) flexible specification of the temporal pattern of technical efficiency into technical inefficiency effects model. The proposed formulation is then applied to the agricultural sector of the EU and US, during the period 1973–1993. The empirical result support the proposed formulation as quite different temporal patterns of technical efficiency have been found for the ten countries included in the analysis. We would like to thank an anonymous referee and an associate editor for valuable suggestions in an earlier version of the paper.

Beyond technical skills training: The impact of credit counseling on the entrepreneurial behavior of Ugandan youth

There is low take‐up of financial credit among youth in Uganda because potential beneficiaries perceive associated risks as high. This study assesses the determinants of entrepreneurial risk tolerance among Ugandan youth using experimental data from a randomized control trial and a real‐life investment‐risk experiment. Credit counseling was provided to young men and women aged 18–35 who owned a business to educate them about the obligations and commitments associated with financial credit. The intervention had a significant impact on demand for credit and related intermediate outcomes such as ownership of a bank account and investment in assets. The study finds that youth exhibited lower demand for credit after business training because of increased awareness regarding the actual risks associated with receiving credit. Our findings reinforce national strategies to promote soft skills for business entrepreneurship that extend beyond standard business training.
