Impact of R&D expenditures,rainfall and temperature variations in agricultural productivity: empirical evidence from Bangladesh

ABSTRACT

This study aims to investigate dynamic relationships between research and development (R&D) expenditure, climate change (measured by annual rainfall and temperature variations), human capital (proxied by literacy) and total factor productivity (TFP) growth in Bangladesh agriculture. Pesaran’s Pooled Mean Group (PMG) estimator is used to a unique panel data of 17 regions of Bangladesh covering a 61-year period (1948–2008). In addition, the panel vector autoregression (PVAR) model is also applied to trace the responsiveness of TFP from a shock to R&D, extension services, and literacy rate. Results reveal that R&D has an insignificant impact on TFP in the short-run, while it has a significant positive impact in the long-run. The contributions of climate variables (i.e., rainfall and temperature variations) are highly significant and negative in the long run. The literacy rate is found to have a significant positive impact on TFP as expected. These results suggest that agricultural R&D investment and human capital could play an important role to ameliorate the adverse effects of climate change in the agricultural sector of Bangladesh.     

R&D and productivity in Danish firms: some empirical evidence

The aim of the paper is to examine the relationship between R&D capital and productivity using microdata for Danish manufacturing firms. The influence of factors such as ownership, innovative characteristics and source of funding accounted for. The return to accumulated R&D capital is estimated to be in the neighbourhood of 9–12%, whereas the short-run effect of R&D is insignificant. Furthermore, the direct influence from foreign ownership, source of funding accounted for, innovative characteristics and ownership dispersion on productivity are analysed. However, none of the factors seem to have an impact on firm productivity. The same is the case for the indirect influence coming from interaction with accumulated R&D capital.     

A new perspective on the exporter productivity premium: online trade

We use a unique firm-level data set including 9000 companies from 26 European Union countries covering four different sectors to take a close look at the relationship between online exports and productivity. The online exporter productivity premium is estimated using different techniques (ordinary least squares, quantile regressions and robust estimation). Results consistently indicate that the estimated online exporter productivity premium is statistically different from zero, positive and significant from an economic point of view. European online exporters, according to these results, are approximately 2% more productive than non-online exporters. Productivity differences between firms could be related to variables that are not included in the empirical model. More research would be needed to address this issue in the future.     

The establishment-size wage premium: evidence from European countries

This study examines the magnitude and determinants of the establishment-size wage premium in five European countries using a unique harmonised matched employer–employee data set (the 1995 European Structure of Earnings Survey). This data set enables to test the validity of various traditional explanations of the size wage gap (i.e. the labour quality hypothesis, the theory of compensating wage differentials, the role of monitoring and institutions) and of more recent hypotheses (i.e. size differences in job stability and in the concentration of skilled workers). We find some support for traditional explanations, but there remains a significant wage premium for workers employed in large establishments. Further results indicate that the magnitude of this premium fluctuates substantially across countries and appears to be negatively correlated with the degree of corporatism.     

Informational mobility and productivity: Finnish evidence

The labor productivity effects of portability and connectivity of information and communication technology (ICT) are studied with Finnish firm-level data. It is found that a computer with only processing and storage capabilities boosts labor productivity by 9% (corresponding to 5% output elasticity), portability by 32%, wireline connectivity by 14%, and wireless connectivity by 6%. The findings are in line with previous literature and comparisons to ICT costs suggest that firms equate marginal costs and returns. Although increasing ICT penetration can no longer be a major source of productivity growth in developed economies, the relatively new characteristics studied can.     

E-commerce,R&D,and productivity: Firm-level evidence from Taiwan

This study investigates the impact of e-commerce and R&D on productivity, using a unique panel dataset obtained from Taiwanese manufacturing firms for the period from 1999 to 2002. We specifically consider the network externalities of e-commerce and employ the system generalized method of moment (GMM) technique to deal with the endogenous problem of e-commerce adoption. The empirical results show that both e-commerce and R&D capital have a positive influence on productivity, while R&D exhibits a larger productivity-enhancing effect. We also find a complementary relationship between e-commerce and R&D on enhancing productivity. Crucially, the inter-industry network externality of e-commerce significantly contributes to productivity.     

R&D,productivity, and exports: Plant-level evidence from Indonesia

This study examines the relation between productivity and exports in Indonesian manufacturing firms by taking account the endogenous choice of R&D. We first examine the determinants of R&D activity and find that exporting activity contributes positively to plants' R&D activity, while multinational corporate do not have a higher R&D propensity. The simultaneous estimates on the interrelation of R&D, productivity, and export show that R&D has a positive impact on both productivity and exports, suggesting the importance of R&D to Indonesian economic growth. It suggests also a two-way causality between productivity and exports, implying the coexistence of self-selection and learning-by-exporting effects in Indonesian manufacturing sector.     

Trade liberalization and productivity dynamics: evidence from Canada

Abstract.  The paper investigates the productivity effects of the Canada-U.S. Free Trade Agreement on Canadian manufacturing. It finds that Canadian tariff cuts increased exit rates among moderately productive non-exporting plants. This led to the reallocation of market share towards highly productive plants, which explains the aggregate productivity gains observed when Canadian tariffs were reduced. The U.S. tariff cuts led to the within-plant productivity gains in exporters and, especially, new entrants into the export market. Any lack of output responses and labour-shedding as a consequence of the FTA was experienced by non-exporting plants, while exporters captured the gains from the FTA.     

Infra-industry spillovers and R&D cooperation: Theory and evidence

We analyse both the theoretical and the empirical side of the issue of R&D spillovers. Each firm's R&D costs are increasing in the amount of information transmitted to other firms, and we account for the possibility that firms control spillovers. We consider both Cournot-Nash and Cournot-Stackelberg behavior. The empirical analysis suggests that (i) firms' control on spillovers is relatively low; (ii) the cost-saving effect associated to joint ventures or R&D cartels is confirmed for industries where firms rely mainly upon own R&D as a source of innovation; (iii) R&D cooperation may increase information sharing, thereby enhancing spillovers.     

Ageing, productivity and wages in Austria: sector level evidence

In this paper we analyse the link between the age structure of the labour force and average labour productivity as well as average wage across industrial sectors. While this intermediate economic level has been under-explored up to now, we will argue that it provides valuable insights in several respects. Our analysis is based on a panel data set ranging over 6 years (2002–2007). It covers the sectors of mining, manufacturing and market oriented services in the Austrian economy. Our results exhibit a positive correlation of the share of older employees and productivity, whereas we cannot find any evidence for a significant relationship of the share of younger employees and productivity. Moreover, the estimated age-wage pattern does not hint at an over-payment of older employees.     

R&D and productivity: evidence from large UK establishments with substantial R&D activities

ABSTRACT

We use Office for National Statistics' micro data for large UK establishments in the production industries in the period 1997–2008 to study the relationship between their productivity and the presence of substantial R&D activities, either at the production unit itself, or at other UK reporting units owned by the same enterprise group. We estimate that total factor (revenue) productivity is on average about 14% higher at the establishments which have substantial R&D themselves, compared to those with no R&D. Among the establishments with no R&D themselves, we estimate that productivity is on average about 9% higher at those which belong to enterprise groups which do have substantial R&D elsewhere in the UK in the same sub-sector. For the establishments with substantial R&D themselves, we also estimate a significant positive relationship between current productivity and past R&D expenditure using dynamic specifications which allow for both establishment-specific ‘fixed effects’ and a serially correlated error component.     

Nonlinear adjustment in the forward premium: evidence from a threshold unit root test

This paper considers testing the mean reversion of the forward premium in a nonlinear framework. In contrast to previous studies, we consider a novel approach that allows for testing for a unit root in the forward premium while explicitly allowing for nonlinearity in the data. Within this approach, we employ bootstrap methods based on threshold autoregressive (TAR) models to investigate whether the 1- and 3-month forward premia for six industrialized countries are mean-reverting. Overall, we are able to reject the null hypotheses of linearity and nonstationarity indicating nonlinear mean reversion. Furthermore, large deviations of the forward premium from its equilibrium band are found to have faster speed of mean reversion than small deviations, which are strongly persistent. In all, the results support the view that the forward premium exhibits mean reversion, but in a special manner not captured by the usual linear tests. Finally, the results have important implications for foreign exchange market efficiency under risk aversion.     

NAIRU and productivity shocks: evidence from three gigantic economies

This article investigates NAIRU which stands for Non Accelerating Inflation Rate of Unemployment and its trend in three of the world gigantic economies to mention orderly USA, Japan and China. A Vector Autoregressive Regression model estimated to study the reaction of NAIRU to shocks imposed by labour productivity. Results indicate both productivity shocks and NAIRU fluctuations have counter effects.     

Firm productivity and agglomeration economies: evidence from Egyptian data

This paper attempts to shed the light on the nexus between firms’ productivity and economies of agglomeration in Egypt. Using a large dataset of firms in 342 firms’ four-digit activities in 27 regions (62,108 firms), we introduce three measures of agglomeration which are urbanization or firm diversification measured by the number of firms by governorate, localization and specialization measured by the average productivity by governorate and sector (generating externalities and knowledge spillovers) and finally competition measured by the number of firm operating in the same governorate and the same sector. We find strong evidence for the existence of agglomeration in Egypt after controlling for firm age, location, economic activity and legal status. In the Egyptian context, productivity spillovers gained from agglomeration measures outweighed the negative effects of competition implied by congestion. The latter is chiefly due to the lack of good infrastructure. When regressions are run by firm size, location and activity, our main findings show first that micro and small firms are more likely to benefit from localization and diversification compared to medium and large firms. Service firms benefit more from high level of diversification while manufacturing firms gain more benefits from knowledge spillovers and specialization in Egypt.     

Employment protection and productivity: evidence from firm-level panel data in Japan

Recent developments in the literature on Employment Protection Legislation (EPL) have revealed that changing the stringency of employment protection can lead to extensive consequences outside the labour market, by affecting firms’ production decisions or workers’ commitment levels. This article provides the first empirical evaluation of the comprehensive effect of restrictions on firing employees in Japan, by exploiting the variations in court decisions. We find that judgements lenient to workers significantly reduce firms’ total-factor productivity growth rate. The effect on capital is mixed and inconclusive, although we obtain modest evidence that an increase in firing costs induces a negative scale effect on capital inputs.     

Basic, applied and experimental knowledge and productivity: Further evidence

Analyzing a novel dataset we find significantly positive effects of basic, and applied and experimental knowledge stocks on domestic output and productivity for a panel of 10 OECD countries. This letter updates the work of, among others, Mansfield (1980), Griliches (1986) and Adams (1990), at an international setting.     

Wage premium in the state sector and state‐owned enterprises: Econometric evidence from a transition country in times of austerity

This paper investigates the differences in the wage premium and compliance with the wage cut introduced in Serbia at the end of 2014, between two subsectors of the public sector: the state sector and state‐owned enterprises. Results show that before the austerity measures were introduced, the conditional wage premium was, on average, higher in state‐owned enterprises than in the state sector, with significant differences from the median to the top of the wage distribution. After the austerity measures were introduced, the wage differences between the subsectors deepened, due to lower compliance of state‐owned enterprises with the wage cut.     

Fighting inflation in Mexico: Theory and evidence

Mexico adopted the inflation targeting strategy in 2002, and this came together with declining inflation. According to the economic authorities, this also brought about lower pass-through of exchange rate changes into inflation. The objective of this article is to test the main hypotheses of Mexico’s prize-stabilization strategy. As a preliminary step, we show evidence whereby the interest rate has not the impact on demand assumed in the conventional view. We then estimate econometric models, which show first of all that inflation depends essentially on the evolution of labor and input costs. Then we demonstrate that higher employment and higher wages associated with higher output do not necessarily entail higher labor costs because productivity also increases when output rises. In the final section, we set forth our main conclusions, which cast doubts on some crucial aspects of the inflation targeting strategy, and propose a different interpretation about why inflation declined in this country.
