Informality,innovation, and aggregate productivity growth

This paper investigates how the costs of innovation in the formal sector temper or magnify the impacts of traditional policy levers such as taxation on sectoral choice. I embed a decision whether to operate formally or informally into a richer, general equilibrium model. Formal firms are subject to taxation, but they can improve their productivity through process innovation. Informal firms can potentially avoid taxation, and their productivity is determined by productivity growth in the formal sector. I find that changing tax rates from 50% to 60% decreases formal‐sector participation by 20.9%; however, this percentage falls by 10% when the cost of innovation is lower in the formal sector. The model also illustrates how changes in tax policy affect total factor productivity growth by limiting both the number of formal‐sector firms and the intensity of innovation. These results indicate a potential mechanism to induce firms to operate formally or mitigate harmful impacts of necessary tax changes.     

R&D,public innovation policy,and productivity: The case of danish manufacturing

The purpose of this paper is to investigate the relationship between private R&D, public innovation support transferred to the private sector, and productivity in Danish manufacturing. Two main conclusions are established. First, public innovation support has a positive and significant effect on private R&D expenditures with an estimated elasticity of 0.062. Second, the indirect effect on productivity from public innovation support is reflected in a positive point estimate which is found to be robust to different specifications of R&D capital.     

R&D and productivity: Internal vs. external R&D - evidence from west german manufacturing industries

The paper explores the productivity effects of investment in external (contract) vs. internal (in-house) R&D in a sample of West-German Manufacturing Industries. The results provide strong evidence of a positive relationship between productivity and the share of external R&D in total R&D. This result is robust to alternative econometric specifications. Thus, findings suggest that the decision between internal and external R&D does matter. Moreover, results imply a nonlinear relationship between productivity and the share of external R&D for higher-technology industries, hinting at decreasing productivity effects of an increasing share of external in total R&D.     

Impediments to innovation faced by Canadian manufacturing firms

Using the findings of the 1999 Survey of Innovation in the Canadian manufacturing sector, we analyse the impediments, i.e. the problems and obstacles, that firms in the sector face when they innovate. In particular, we assess the factors which inhibit innovation, especially with regard to by small and medium enterprises (SMEs). First we try to establish the relationship between the impediments to innovation and various firm characteristics. Then we assess whether these impediments actually prevent firms from innovating or whether firms are able to overcome them.

We find that the perception of impediments to innovation vary according to firm characteristics. For example, large firms are more likely to report the high cost of developing innovation and organizational rigidities as impediments than small firms. However, they seem to have less difficulty with regard to financing innovation projects compared to SMEs. Our results also show that firms seem to be able to overcome most of the obstacles to innovation. Therefore, the impediments featured in innovation survey(s) should not be interpreted as impenetrable barriers that prevent innovation. The sole exception is organizational rigidities. Firms facing organizational rigidities are less likely to become innovative, whether they are small, medium, or large. From our results, we conclude that small firms do not face particular impediments which prevent them from becoming innovative.     

Dynamic models of R & D,innovation and productivity: Panel data evidence for Dutch and French manufacturing

This paper introduces dynamics in the R&D-to-innovation and innovation-to-productivity relationships, which have mostly been estimated on cross-sectional data. It considers four nonlinear dynamic simultaneous equations models that include individual effects and idiosyncratic errors correlated across equations and that differ in the way innovation enters the conditional mean of labor productivity: through an observed binary indicator, an observed intensity variable or through the continuous latent variables that correspond to the observed occurrence or intensity. It estimates these models by full information maximum likelihood using two unbalanced panels of Dutch and French manufacturing firms from three waves of the Community Innovation Survey. The results provide evidence of robust unidirectional causality from innovation to productivity and of stronger persistence in productivity than in innovation.     

Advanced technology,innovation, wages and productivity in the Canadian manufacturing sector

In this article, we used a two-step estimation procedure, where in the first stage, the number of advanced manufacturing technologies used in the firm was estimated using a negative binomial regression, and the expenditure on process and product innovation was estimated using a type II Tobit procedure. In the second stage, we used the predicted values from the first stage in wage and labour productivity equations. The data were from the 2009 Survey of Innovation and Business Strategy which was linked to the General Index of Financial Information (2004–2009) and the Longitudinal Employment Analysis Program (2004–2009). The implications for policy are that we should not expect large aggregate effects of innovation on productivity and employment. We should expect wage increases and productivity increases, with process innovation. We should also expect moderate wage increases with product innovation, and contrary to process innovation, the effect on productivity of product innovation was negative.     

Infrastructure investment and Canadian manufacturing productivity

This paper examines the relationship between Canadian public infrastructure and private output using a Constant Elasticity and Substitution-Translog (CES-TL) cost model to describe the interaction of the public and private sectors.

We find public capital a substitute for private capital within the Canadian manufacturing sector. Additionally, the services of public capital enhance the productivity of private capital. Canadian manufacturing costs are characterized by economies of scale, indicating that less than optimal plant sizes dominated Canadian manufacturing sector during the study period. Advances in disembodied technical progress are also indicated.     

Micro-heterogeneity and aggregate productivity development in the German manufacturing sector

A decomposition of aggregate productivity growth of German manufacturing firms that pertain to 11 different industries at a roughly two-digit level observed over the period 1981–1998 is performed. Productivity is measured by a nonparametric frontier function approach. The decompositions of productivity allow for an explanation of the aggregate outcomes by the quantification of the effect of structural change and the contributions of entering and exiting firms. Our results show that these forces drive aggregate productivity to a considerable extent. Remarkably, the large productivity improvements after the German reunification are mainly driven by structural change.

Growth of factor productivity in Turkish manufacturing industries

This paper presents estimates of rates of total factor productivity (TFP) growth for two-digit manufacturing industries in Turkey over the period 1963 to 1976. Estimates are presented separately for the public and private enterprises in each industry. It is shown that periods of slower productivity growth coincided with periods of a more stringent traderegime. It is also shown that, despite the fact that the rate of growth of TFP was about the same in the public and private sectors, absolute levels of inputs in the public sector enterprises are much higher than in their private sector counterparts.     

Adjustment costs and factor demands in Canadian manufacturing industries

This paper examines whether there is a relationship between the commodity terms of trade (the price of primary commodities relative to the price of manufactures) and the net barter terms of trade of 42 Sub-Saharan African countries. For most countries, there is little evidence of a stable, long-run relationship between the two terms of trade series. Accordingly, the practice in the literature of proxying for movements in any given country's terms of trade by using an aggregate index of relative commodity prices is inappropriate, and is likely to engender misleading policy conclusions.     

Environmental regulations and innovation activity in UK manufacturing industries

We examine the relationship between environmental regulations and innovation, using data from UK manufacturing industry during 2000-2006. We estimate a dynamic model of innovation behaviour, and explicitly account for the likely endogeneity of our measure of the stringency of environmental regulations (pollution abatement costs). Our results indicate that while on the one hand environmental R&D and investment in environmental capital are stimulated by greater pollution abatement pressures, on the other hand there is not a positive impact of environmental regulation on total R&D or total capital accumulation. We find some evidence that this is because more stringent environmental regulations directly lower the optimal expenditure on non-environmental innovations. In addition, we find that environmental R&D may crowd out non-environmental R&D, although there is no evidence that environmental capital crowds out non-environmental capital.     

Environmental regulation and the productivity of Japanese manufacturing industries

This paper attempts to provide empirical evidence on issues concerning: (a) the effect of the stringency of environmental regulations (as measured by pollution control expenditures) on innovative activity (as measured by R&D expenditures) and on the average age of capital stock and (b) the productivity enhancement effect of environmental regulations in Japanese manufacturing industries. The empirical findings in the paper show that the pollution control expenditures have a positive relationship with the R&D expenditures and have a negative relationship with the average age of capital stock. It is also shown that increases in R&D investment stimulated by the regulatory stringency have a significant positive effect on the growth rate of total factor productivity.     

Exchange rate pass-through and its determinants in Canadian manufacturing industries

In this paper the pass-through of exchange rate changes into the real prices of domestically produced and imported goods in Canadian manufacturing industries is examined through industry estimates of the pass-through elasticities and a cross-section analysis of their determinants. We find that the domestic pass-through elasticity increases with the effect of the exchange rate on domestic costs of production, the export share, the elasticity of substitution between imports and domestic goods, and the domestic advertising intensity. The import elasticity increases with the elasticity of substitution and the rate of price protection and decreases with advertising intensity. JEL Classification: L60, F14
Les effets de changements dans le taux de change sur les prix réels dans les industries manufacturières canadiennes. Ce mémoire examine les effets des changements dans le taux de change sur les prix réels des biens produits au Canada ou importés pour les industries manufacturières canadiennes en construisant des estimés par secteur des élasticités de transfert et en examinant leurs déterminants dans une analyse trasnversale. On montre que l'élasticité de transfert domestique s'accroît à proportion que l'effet du taux de change sur les coûts internes de production, la part des exportations, l'élasticité de substitution entre importations et biens domestiques, et l'intensité de publicité au plan interne sont importants. L'élasticité des importations s'accroît avec l'élasticité de substitution et le taux de protection des prix, et décroît avec le niveau d'intensité de la publicité.     

Determinants of domestic and import prices in Canadian manufacturing industries

This paper examines the determinants of the prices of domestic and imported goods in the domestic market using time-series data for a broad sample of Canadian manufacturing industries. It is found that the costs of both goods are the fundamental determinants of their prices, that the pass-through of costs into prices depends on the levels of domestic and import costs, real income per capita and concentration, and that factors which increase the sensitivity of both prices to domestic costs also reduce their sensitivity to import costs. In addition, it appears that the way in which prices are determined differs between industries with low versus high advertising-sales ratios.     

Determinants of investment and innovation expenditure in Polish manufacturing industries

This article analyses determinants of sectoral R&D and innovation expenditure as well as investment in Polish manufacturing industries in 1994–2004. The estimated coefficients for user cost of capital are generally in line with the neoclassical model of investment, except for R&D intensity. The latter are primarily discouraged by systemic uncertainty. The rate of growth of sales is not a prominent determinant of investment and innovation expenditure. Market concentration coupled with uncertainty has a damaging effect on physical capital investment but it promotes R&D expenditure and leaves innovation intensity unaltered.     

Exchange rate fluctuations and labour market adjustments in Canadian manufacturing industries

We estimate the link between exchange rate fluctuations and the labour input of Canadian manufacturing industries. The analysis is based on a dynamic model of labour demand and the econometric strategy employs a panel two‐step approach for cointegrating regressions. Our data are drawn from a panel of 20 manufacturing industries from the KLEMS database and cover a long sample period that includes all cycles of appreciation and depreciation of the Canadian dollar over the last 50 years. Our results indicate that exchange rate fluctuations have significant long‐term effects on the labour input of Canada's manufacturing industries, especially for trade‐oriented industries, but that these long‐term impacts materialize very gradually following shocks.     

Generation and distribution of the total factor productivity gains in US industries

This study estimates productivity gains and their distribution among inputs and outputs for 63 American industries over the period 1987–2012. Using the traditional surplus accounting method, the Total Factor Productivity (TFP) growth rates are divided into their price change components in order to determine the stakeholders who do or do not receive price advantages.

An initial analysis showed that TFP of US industries increased at an average trend of 0.8% and established that remunerations to employees and firms’ profitability constituted 49% and 39%, respectively, of the accumulated economic surplus from the productivity gains. Suppliers of intermediate inputs retained 12.1% of the surplus. Finally, customers, equipment and structure providers were the losers in the distribution of economic surplus via, respectively, a significant growth of relative final demand prices and a substantial price decrease of these assets.

A second step analysis underlined that industries with high TFP growth rates mainly benefited customers and firms via output price decreases and profitability improvements while industries with low or negative TFP changes hurt customers through significant output price increases. The sectoral level analysis also showed that employees’ remunerations depend only slightly on productivity gains produced within their industrial sectors.     

Entry,exit and productivity growth: Spanish manufacturing during the eighties

This paper analyses the role played by both competitive pressure (increasing imports) and the restructuring of industries through entry and exit in productivity growth of Spanish manufacturing during the eighties, the key period of its accession to the EEC economy. A GMM panel estimation of the determinants of corrected Solow residual for 75 manufacturing during 1979-1990, shows that these forces accounted for 80% of productivity growth, playing an important role the displacement of inefficient firms by competitive entry.JEL Classification: D24, C33We are grateful to S.

R&D and productivity growth: Evidence from the UK

Although the econometric evaluation of R&D has attracted wide interest in many countries, it has not attracted much in the UK. The main objective of this paper is to fill this void, i.e., to estimate the impact of R&D on productivity growth of the UK manufacturing sector. However, there are some additional objectives. Firstly, we estimate the impact of R&D on productivity growth of large and small firms and we discuss a number of theoretical arguments regarding the role of firm size. Secondly, given that the technological infrastructure influences the innovative capacity of a firm, we compare the impact of R&D on productivity growth of high-tech firms with the corresponding impact on productivity growth of low-tech firms. Thirdly, we investigate whether the contribution of R&D to productivity growth has changed over time.

Based on firm-level data (78 firms, 1989–2002), we find that the contribution of R&D is approximately 0.04. Although the R&D-elasticity of large firms (0.044) is higher than the corresponding elasticity of small firms (0.035), the difference is small. In contrast, the R&D-elasticity is considerably high for high-tech sectors (0.11), but statistically insignificant for low-tech sectors. Finally, the investigation of the elasticity of R&D over time revealed an interesting discontinuity showing that although until 1995 the R&D-elasticity was approximately zero, after 1995 it increased dramatically to 0.09. We investigate the potential causes of such non-linearity and we suggest a number of possible explanations.
