Technology,productivity, and industry structure

This paper examines the controversy as to the particular firm size or industry structure that is most conducive to innovation. Four major conclusions emerge from the considerations advanced here. First, contrary to the focus of the controversy, the relevant issue is not one of the economic statics. Rather, it is one of technological dynamism. Second, variety is an essential ingredient of innovative activity, which can be sustained only through equivalent variety in firm size and industry structure. Thus, there is no one single optimum firm size or industry structure. Third, the origin of interindustry differences in innovation and productivity growth lies in certain processes of cumulative causation involving a multiplicity of variables rather than any one single factor at the exclusion of all others. In consequence, we find that productivity does not advance in a uniform manner across various industries. Rather, it is characterized by an inherently uneven pattern of growth. Fourth, it is pointless to strive for a balanced growth between various sectors of the economy. Rather, an effective policy is one of deliberately lopsided growth whereby fuller development of progressive industries makes it possible to generate the additional resources required for investment in the backward industries. Finally, while the policy to stimulate technical progress and productivity growth must be formulated in a broader socioeconomic context, its focus ought to be on the internal dynamics of technical change processes.     

Technology transfers,foreign investment and productivity spillovers

This paper explores the relationship between foreign direct investment (FDI) and the productivity of host country domestic firms. We rely on a specially designed survey of over 4000 manufacturing firms in Vietnam, and separate out productivity gains along the supply chain (obtained through direct transfers of knowledge/technology between linked firms) from productivity effects through indirect FDI spillovers. In addition to identifying indirect vertical productivity spillovers from FDI, our results show that there are productivity gains associated with direct linkages between foreign-owned and domestic firms along the supply chain not captured by commonly used measures of spillovers. This includes evidence of productivity gains through forward linkages for domestic firms which receive inputs from foreign-owned firms.     

Computerization,workplace organization,skilled labour and firm productivity: Evidence for the Swiss business sector

The present study explores empirically the hypothesis that information and communication technologies, new organizational practices and human capital are important determinants of firm efficiency and performance, further that the combined use of these three factors leads to a mutual strengthening of their impact on firm performance. The analytical framework is that of a production function at firm level. The new contribution of this study to the empirical literature is that it is the first empirical study of this type for the Swiss business sector, using a rich data set at firm level for the year 1999 which were collected by means of a postal survey, and giving particular attention to the complementarity issue (several approaches) and to the endogenization of the technology and organization variables.     

Technology diffusion,spatial effects and productivity growth in the Chinese provinces

This paper investigates spatial spillover effects of productivity in China. We set up a model in which a Chinese province achieves productivity growth by taking advantage of productivity spillovers from the world frontier and from other Chinese provinces. By using fixed effects and GMM panel data methods, we show that productivity growth in an inland province in China can be partly attributed to productivity spillover effects of other provinces. We also show that provincial human capital plays an important role in determining the magnitude of these spillover effects.     

Technology adoption and the impact on average productivity

In this paper, a framework is developed to analyze how the specifications of new technologies and the heterogeneity of micro-units of production affect the input use, the adoption pattern, and the productivity of inputs. It shows that asset-productivity-enhancing (APE) technologies tend to be adopted by micro-units with high-quality assets, while variable-input, efficiency-enhancing (VIEE) technologies tend to be adopted by micro-units with low-quality assets. In both cases, the variable input productivity increases, but the average productivity of the fixed asset may decline in the case of the VIEE technology. The distribution of asset quality and the new technology specifications will therefore determine the impacts of production technology innovations on aggregate behavior and consequently the change in average productivity of the fixed asset.     

Rent-seeking,R&D,and productivity

To investigate whether rent-seeking discourages productivity, we consider a third-market model, in which a domestic firm and a foreign firm engage in both Research and Development (R&D) and output competition. We show that the relationship between rent-seeking and productivity depends on two forces. On the one hand, rent-seeking increases the marginal benefit of R&D and encourages productivity. On the other hand, a lower production cost due to R&D enables the government to extract the rent from the firm to a greater extent and discourages the productivity. Which force is dominant depends on the level of corruption or, as an alternative interpretation, the weight the government attaches to political contributions. Unlike the monotonic relationship proposed by the literature, we find a non-monotonic relationship between rent-seeking and productivity.     

Transparency, entry, and productivity

This paper studies the relationship between transparency on the consumer side and productivity of firms. We show that more transparent markets are characterized by higher average productivity as firms with low productivity abstain from entering these markets.     

Exporting, productivity and agglomeration

Economic analysis of adjustment to globalisation has shifted from countries and industries to firms and plants. One particularly fruitful area for research has been aspects of entry to, participation in and exit from export markets. This paper contributes to that literature. Its focus is the exporting behaviour of manufacturing firms in the United Kingdom. To isolate the impact of participation in export markets we use nearest neighbour matching. For 1988-2002, we find evidence that spillovers associated with agglomeration can raise the probability of export market entry and once entry has occurred there may be additional productivity benefits. Survival is driven partly by size and total factor productivity and partly by industry characteristics.     

Innovation,competition and productivity

We investigate the drivers of firm‐level productivity in catching‐up economies by jointly estimating its relationship to innovation and competition using data from the EBRD‐WB Business Environment and Enterprise Performance Survey (BEEPS) in Eastern Europe and Central Asia. The findings confirm an inverted‐U shaped impact of competition on R&D. Both competition and innovation have a simultaneous positive effect on labour productivity in terms of either sales or value added per employee, as does a high share of university graduates and foreign ownership. Further positive impacts come from firm size, exports or population density. Innovation and foreign ownership appear to be the strongest drivers of multifactor productivity.     

Incentives,supervision, and sharecropper productivity

Though sharecropping remains widespread, its determinants are still poorly understood and the debate over the extent of moral hazard is far from settled. We address both issues by analyzing the role of landlord supervision. When landlords vary in their cost of supervision, otherwise identical share-tenants can have different productivity. Unique data on monitoring frequency collected from share-tenants in rural Pakistan confirms that, controlling for selection, ‘supervised’ tenants are significantly more productive than ‘unsupervised’ ones. Also, landlords' decisions regarding monitoring and incentives offered to tenants depend importantly on the cost of supervision.     

Information,capital, and organization

Summary This paper examines on of the roles that information plays in the production process by looking at the information that firms collect about their workers. This information, concerning the worker's abilities, is used to improve the quality of job matches within the firm and reduce future production costs. This paper models this information as a capital good and shows how the existence of this capital good can be used to explain some of the residual firm value observed in equity markets as well as the rigidities observed when firms expand their scale.I would like to acknowledge the assistance of Edward Prescott, Hugo Hopenhayn, Herbert Mohring and Jim Schmitz who provided many insights and comments concerning this work.

Export,FDI and firm productivity

Many empirical papers tested the theoretical predictions of Helpman, Melitz and Yeaple (HMY, 2004) which sorts firms at different internationalization states according to their productivity levels. While these papers ignore the fact, that the theoretical predictions of HMY only apply to firms that become engaged in market-driven Foreign Direct Investment (FDI), we apply a more precise methodology using a French firm sample with more than 110?000 observations. Our results show that firms with a broader investment strategy, reflecting a great importance of market-driven motives, show higher productivity levels than firms with less encompassing foreign investment strategies. We conclude that the methodology is well-suited to sort firms according to the importance of market-driven FDI.     

Firm productivity,wages, and agglomeration externalities

Using detailed census data from Morocco, this paper investigates the existence of local externalities in manufacturing. In contrast to many other studies that focus on aggregate employment growth, we examine the effect of externalities on firm-level productivity and wages. Our empirical results show that agglomeration externalities occur through both productivity and wage effects. Returns to specialization are strong and large in magnitude. In accordance with the views of Marshall, Arrow and Romer, the net effect of competition on productivity and wages tends to be negative. Large firms facing no local competition have higher revenues and pay lower wages. We also find some limited evidence in favor of the diversity argument put forth by Jacobs.     

Manufacturing consumption,relative prices,and productivity

I study the patterns of manufacturing consumption expenditures across a broad set of countries that differ in their level of development using disaggregated expenditure and price data. The relative price of manufacturing tends to decline with income and the real share rises with income, particularly for countries in the top half of the income distribution. I find that the nominal expenditure share of manufacturing displays a hump-shape pattern with respect to the level of income per capita. I document that the income elasticities of the relative price of individual manufacturing categories lie in a wide range. However, since most categories have a negative elasticity, the average elasticity for manufacturing is negative. In addition, most aggregations of individual categories, regardless of the criteria used, yield manufacturing sub-sectors that feature a negative income elasticity of its relative price and the variation across income in nominal expenditure shares tends to mask a larger variation across income in real shares. Using a standard development accounting framework, I report large differences in productivity across countries for manufacturing categories. I also find some differences in productivity across countries for manufacturing sub-sectors, but these differences are smaller than the differences between manufacturing and services and considerably smaller than the differences across individual manufacturing categories.     

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.     

The outsourcing productivity paradox: total outsourcing, organisational innovation, and long run productivity growth

A growing number of empirical studies find a relationship between the outsourcing of activities and a long term loss of firm productivity growth. The paper addresses this outsourcing productivity paradox by examining the connection between total outsourcing and organisational innovation. We present a model of organisational innovation in which managers raise productive efficiency by identifying organisational architectures that more effectively integrate value-adding activities and administrative routines. As part of this process, managers can internally or externally source an activity. Simulations of the model show that large scale outsourcing restricts the scope for future organisational innovation, leading to lower productivity growth. The findings accord with the empirical data and provide a salutary warning for managers and policy-makers about the long term implications of total outsourcing.

Community banks,money and labour productivity

Does money affect productivity? We examine whether bank deposits, a measure of the money supply that excludes currency in circulation, influence labour productivity. Banks deposits are special in that they facilitate transactions and, in aggregate, add liquidity and credit availability to a region. By exploiting the distribution of community bank deposits across the states, we test the hypothesis that money is an input to the production function under a variety of panel data methods. We find evidence that bank transaction deposits and total deposits along with other production function inputs such as wages, labour and gross state product are cointegrated across the states; however, the economic contribution of money to labour productivity appears limited.
