Innovation,productivity and exports: the case of Hungary

This paper estimates the relationship between innovation and firm performance by using Community Innovation Survey data for Hungary. It exploits the possibility of linking the innovation data to ownership and disaggregated trade data. Innovative firms are more productive, more likely to trade and export more products to more countries. We also test for differences in innovative behaviour in high- and low-tech industries, and study whether domestic and foreign firms differ in this respect.

Innovation,exports, productivity and investment climate; a study based on Indian manufacturing firm-level data

In this paper, we use univariate instrumental estimations to study the interactions between firm-level innovation, exports and productivity in the Indian manufacturing sector. To differentiate incentives to innovate from the ability to innovate, we distinguish the inputs of innovation (R&D and training) from the outputs. Our findings highlight a virtuous circle between the three components of innovation, as well as between firms’ R&D, innovation and exports. The productivity of Indian manufacturing firms is benefiting from this dynamics, as exports and innovation improve firms’ TFP. With respect to the investment climate, our results suggest that differences in the environment of Indian companies contribute to their performance gaps. These results are all the more important in the context of the Make in India campaign and the weaknesses of India’s business environment.     

The distributional effects of selection and capital accumulation on firm productivity under imperfect capital markets

In this evolutionary model, random shocks create differences in the rate of return on capital, while individual saving and investment behavior can reduce these differences over time. Firms with either low total factor productivity (TFP) or a low average return on capital are selected for exit, and new firms enter to take their place. As would be expected, a higher turnover rate improves TFP and reduces its variation. While we show that a higher turnover rate would result in a more positively skewed TFP distribution if exit selection is based directly upon TFP, we find that when we select firms for exit based on their average product of capital, the marginal impact of a higher turnover rate is to more negatively skew the TFP distribution. Overall, our simulations highlight the importance of considering the role selection may play in shaping the distribution of productivity when econometricians seek estimates of firm inefficiency.

Decomposing the contribution of firm innovation to aggregate productivity growth: the case of Chinese manufacturing industry

This article proposes a generalized productivity decomposition approach to evaluate the contribution of firm innovation to aggregate productivity growth (APG) of China’s manufacturing industry. Results indicate that APG is mainly driven by firm-level productivity improvements, while across-firm resource misallocations lead to sizable productivity losses. The weak contribution of firm innovation to APG is found to be mainly caused by resource misallocations within innovating firms. The results suggest that firm innovation has not yet taken a dominant driving force for APG.     

Entry,growth, and survival: The new learning on firm selection and industry evolution

This paper tries to shed some light on the seeming paradox posed by the findings in the industrial organization literature that (1) the bulk of firms in an industry are not only very small, but also sufficiently small so that they are operating at a sub-optimal scale of output, and (2) entrepreneurs are apparently not deterred from starting new firms even in industries where scale economies play an important role. A dynamic view of the process of firm selection and industry evolution is that new firms typically start at a very smal scale of output. Because this level of output may be sub-optimal, the firm must grow in order to survive. The empirical evidence supports such a dynamic view of the evolutionary nature of industries. Viewed through a dynamic lens, the often-observed asymmetric size distribution of firms becomes more understandable. The persistence of an asymmetric firm-size distribution skewed towards small enterprises presumably reflects a continuing process of entry into industries and not necessarily the survival of such small and suboptimal enterprises over a long period of time.     

Technological progress and market growth: An empirical study based on the quality-ladder approach

This paper develops an extended version of the quality-adder model by allowing for heterogeneous markets. Based on this model, it presents an empirical analysis of innovation-based growth at the market level using a technometric measurement concept. It can be shown that a growth-promoting effect due to technological progress in a particular single year is observed after between 2 and up to 7 years. This is true not only for highly innovative markets but also for those in which fewer R&D resources are invested.     

The effect of strategic alliances on firm productivity in South Korea

Using a rich firm-level data set from South Korea, this article analyses the impact of strategic alliances on firm performance, focusing on how firm productivity is affected by alliance types such as joint venture, joint technical development, technical alliance, joint marketing and coproduction as well as alliance structures such as intra- and inter-industry alliances. Total factor productivity (TFP) is estimated through the semi-parametric method suggested by Levinsohn and Petrin (2003). In addition, a two-stage least-squares (2SLS) method is applied to reduce the potential endogenous problem between productivity and strategic alliance choices. The empirical results found in this article indicate that the engagement in joint ventures positively affects firm productivity and that the formation of international intra-industry alliances has a positive impact on firm productivity.     

Sources of productivity growth using the Färe-Primont decomposition. An empirical application to the Irish beef sector

Several competing methodologies for TFP estimation have been developed in the past decades. A popular approach in the literature is index number computation. The most widely implemented TFP indices face however several important limitations. For example, Fisher, Tornqvist or Malmquist TFP indices do not satisfy the transitivity test, precluding reliable direct inter-temporal comparisons. The recently developed Färe-Primont TFP index satisfies this property, and therefore it is applied to analyse the evolution of TFP in the Irish beef sector between 2010 and 2016. Moreover, this index is multiplicatively complete, allowing a consistent decomposition of TFP growth in different sources. The sample of Irish beef farms used in the analysis is clustered to account for differences in production technology in the sector. The cluster-specific TFP changes computed were found to present important differences across the seven clusters identified. Significant TFP growth was identified in five of the classes, while TFP declined for the other two. Dispersion and mobility of the TFP levels indicate a lack of structural changes in the sector regardless of the cluster considered.     

The impact of trade costs on exports: An empirical modeling

Studies, which have discussed some of the important issues concerning the measurement of trade costs, have conceded that the literature is still in the early stages of understanding and measuring what the real costs are. It is in this context, decomposing trade costs into ‘natural’ costs, ‘behind the border’ costs, ‘explicit beyond the border’ costs, and ‘implicit beyond the border’ costs, this paper suggests a method to measure the impacts of these components on changes in exports between countries in the absence of complete information on all the components of trade costs in home and partner countries. Empirical measurement has been demonstrated using 1999 and 2004 trade data from Pakistan. The results show that Pakistan's export growth between 1999 and 2004 came mainly from the reduction in both ‘explicit and implicit beyond the border’ trade costs in partner countries.     

A grey dynamic model for the evaluation of regional sustainable development and its empirical study

Currently, traditional development issues, such as economic stagnation, as well as new challenges like environmental degradation and globalization, need attention. Sustainable development, including economic, environmental, and social elements, is a main goal of decision-makers. The key to sustainable decision-making is to evaluate and forecast the status quo of sustainable development. Policy makers need a tool based on scientific information to forecast the effects of future actions on sustainability and make policies for sustainable development. This paper analyzes the relation of the economy, environment and social welfare by the grey dynamic model. The proposed method uses time series and basic indicators of ecological system, including economic, environmental and social sub-systems. It is applied to Heilongjiang Province and Jiangsu Province. The results have proved different status quo of sustainable development in these two regions, and suggestions are proposed, such as optimization of industrial structure and eco-industrial development. The conclusion is that there is no unique sustainable path, and accordingly, policy makers should choose different criteria and strategies to make efficient sustainable decisions for each region.     

Assessing the impact of domestic outsourcing and offshoring on productivity at the firm level

The purpose of this article is to investigate the effects of domestic and foreign sourcing on firm-level productivity. We develop a simple framework that permits the introduction of both domestic outsourcing and offshoring in a conventional production function. We find that the decision to outsource has a positive impact on the level of productivity as it permits the relocation of parts of the production process to external suppliers. Furthermore, there is a positive impact on output resulting from domestic outsourcing and offshoring like any other input.     

出口强度、资本密集度对中国出口企业自选择效应和学习效应的影响

现有研究关于出口企业自选择效应和学习效应的检验常常忽视企业的微观特征。本文通过对中国大样本微观面板数据进行统计分析和计量检验表明：国内出口企业存在生产率的静态优势,不存在“生产率悖论”。总体层面上,出口企业存在自选择效应,并且这种自选择效应对各种所有制企业和不同资本密集度企业均存在。在考虑国内外市场进入成本的情况下,高生产率的企业选择同时进入国内外两个市场,表现出自选择效应;而低生产率、高出口强度的企业选择进入国外市场,不存在自选择现象。,此外,短期内持续出口企业的学习效应为负,并且各种所有制企业的学习效应稳健为负,怛高资本密集度企业的出口学习负效应能快速扭转为正,出口强度低于50％的企业学习效应显著为正。     

Effects of temporal heterogeniety in the Baumol-Wolff productivity growth model

Summary. In their utilization of R&D (information) output, different sectors of a heterogeneous industry display different reaction times. This paper analyzes the effects of this temporal heterogeniety on output and productivity for an extended version of the Baumol-Wolff model. Results include conditions implying persistent, non-decaying oscillations in the output and hence also in the productivity rate. Received: January 26, 1998; revised version: January 8, 1999     

Revisiting the threshold effect of remittances on total factor productivity growth in South Asia: a study of Bangladesh and India

Both Bangladesh and India are among the top recipient of remittances in absolute terms. However, in relative terms – remittances as a per cent of GDP – the two countries stand at 6.1% and 2.8%, respectively, well below the levels of the top 10 recipients. In this article, we explore the effect of remittances on the total factor productivity (TFP) growth considering Bangladesh and India, as reference countries over the periods 1980–2012 and 1977–2012, respectively. We examine the presence of a long-run association between remittances and TFP using a number of tests. The results indicate that remittances have threshold effects on TFP growth in both countries. Despite the two countries receiving substantial amount of remittances, we note that Bangladesh has a U-shaped relationship whereas India has an inverted U-shaped relationship with TFP growth. For Bangladesh, a minimum threshold of remittances (% GDP) is 5.3% and for India, a tipping point of remittances (% GDP) is at 1.8%. The causality tests confirm a bidirectional effect, which implies that remittances and TFP growth are mutually reinforcing. Interestingly, while the two economies have similar remittances impact in regards to causality, the study highlights two different tipping points of remittances.     

Road to productivity: Effects of roads on total factor productivity in Indian manufacturing

A denser road network lowers transport costs and stimulates manufacturing total factor productivity (TFP). The placement of roads, however, is likely to be non-random. For identification, we exploit cross-state variation in the strength of centre-state partisan alignment that asymmetrically affects road building in aligned states. Using panel data on manufacturing establishments in India from 1998 to 2012, we find that, a 1% increase in road density raises value-added TFP by about 0.25%, on average. A closer examination reveals that the effect varies by plant characteristics and road type. Younger establishments are more likely to gain from a denser road network with highways playing a prominent role. The results are robust to imperfections in the instrument and to other sensitivity checks.     

Understanding TFP growth in inland regions of China: an empirical study of the effects of three factors

In this paper, we empirically examine the potential effects of international openness, domestic coastal-inland market integration, and human capital accumulation on TFP growth in inland provinces in China. By using a nonlinear technique as our main regression approach as well as an extended GMM method as robustness checks, we show that human capital accumulation plays an important role in promoting TFP growth in the inland provinces. Our results support the argument that the most important contribution of human capital to income growth lies not in its static, direct effect as an accumulable factor in the production function, but in its dynamic role in promoting TFP growth. Our regression results also provide evidence for the positive roles international openness and domestic coastal-inland market integration play in promoting TFP growth in inland provinces in China.     

The stability of the production function and the marginal productivity of inputs: An empirical study

This paper tests for the stability of the aggregate production function of the United States from 1929 to 67 with two inputs (labor and capital) and with three inputs (labor, capital, and real balances). The results show parametric instability regardless of the inclusion of real balances. Using the varying parameters estimation method allowing for permanent and transitory shifts in the parameters, time-series estimates of the marginal productivity of capital, labor, and real balances are derived for the period 1929–1967. The temporal behavior of the marginal productivity of real balances is briefly analyzed.     

'Total factor productivity vs. realism' revisited: the case of the South Korean steel industry

This paper presents key features of the development of the SouthKorean steel industry through the critical examination of anarticle by Truett and Truett. Despite their claim to exhibit‘realism’ by use of a translog cost function, theirmethodology has strong affinities with the methods of measuringtotal factor productivity growth, which have long been knownas invalid but continue to be applied not least to the experienceof East Asian countries. It will be argued that the theoreticaland empirical flaws involved with these methods invalidate theirresults and corresponding policy implications. Above all, byshowing that the assumptions for their calculation do not holdin terms of the economic conditions of the industry, the paperpoints to a different understanding of ‘realism’than that conceived by and for their study.
