We use a dynamic model to measure the impact of the entry of large stores on incumbents’ productivity separate from demand while accounting for local markets and the endogeneity of entry. Using data on all retail food stores in Sweden, we find that incumbents’ productivity increases after the entry of large stores and that the magnitude of the increase declines toward the upper part of the productivity distribution. Our findings highlight that large entrants drive productivity.  相似文献

We analyze the cost of quality improvement in hospitals, dealing with two challenges. Hospital quality is multidimensional and hard to measure, while unobserved productivity may influence quality supply. We infer the quality of hospitals in Los Angeles from patient choices. We then incorporate ‘revealed quality’ into a cost function, instrumenting with hospital demand. We find that revealed quality differentiates hospitals, but is not strongly correlated with clinical quality. Revealed quality is quite costly, and tends to increase with hospital productivity. Thus, non-clinical aspects of the hospital experience (perhaps including patient amenities) play important roles in hospital demand, competition, and costs.  相似文献

We study the impact of process and product innovations introduced by firms on employment growth with random samples of manufacturing and services from France, Germany, Spain and the UK for 1998–2000, totaling about 20,000 companies. We develop and estimate a model relating firms' and industry's employment to innovation, that leads us to the conclusions that follow. Trend increases in productivity reinforced by process innovation are an important source of reduction of employment requirements for a given output, but the growth of demand for the old products tends to overcompensate these displacement effects. The switch of production towards new products does not reduce employment requirements, and the growth of the demand for the new products is the strongest force behind employment creation. Reallocation due to business stealing is estimated at a maximum of one third of the net employment created by product innovators. The growth of employment originated from the market expansion induced by the new products can be as important as another third.  相似文献

We examine the effect of unionization on police productivity in large U.S. metropolitan areas. We define police output in the context of a production function model that draws also on the crime literature. We estimate the resulting model using a data set that includes published and unpublished government statistics as well as our own survey of police departments. Results suggest that the effect of unions on police productivity varies according to categories of police performance. In particular, if performance is stratified according to the severity of crimes, unions seem to have an insignificant effect on police productivity with respect to serious crimes. For minor crimes, unionization alters the parameters of police production function, leading to diminished productivity.  相似文献

Central Asia has experienced massive economic and social shocks during the past decade following the dissolution of the former Soviet Union. Demand for cereals, particularly for staple cereals and meats, has fallen significantly even as production and productivity have plummeted. Although agricultural reforms were launched in 1991, the performance of the agricultural sector has been weak across the region. Prospects for food security in Central Asia appear mixed. Projections indicate that a growing and urbanizing population in Central Asia with rising incomes will increase demand for cereals by 32% between 1995 and 2020 to reach 24 million tons, and for meat by 47% to reach 2.9 million tons. Improvements in crop productivity will be essential to meet the increases in demand projected for the region. Cereal production is forecast to keep pace with demand such that Central Asia will be virtually self-sufficient in cereals. However, national food self-sufficiency or food security does not necessarily translate into household or individual food security. Moreover, self-sufficiency comes with a high price-tag of opportunities foregone and inappropriate use made of resources. Given the growing enthusiasm for food self-sufficiency in Central Asia, it is imperative that research be undertaken to assess the full costs and benefits of such a policy.  相似文献

We use a macro‐econometric forecasting model to simulate the impact on the Canadian economy of a hypothetical increase in immigration. Our simulations generally yield positive impacts on such factors as real gross domestic product (GDP) and GDP per capita, aggregate demand, investment, productivity, and government expenditures, taxes and especially net government balances, with essentially no impact on unemployment. This is generally buttressed by conclusions reached in the existing literature. Our analysis suggests that concern should be with respect to immigrants themselves, as they are having an increasingly difficult time assimilating into the Canadian labour market, and new immigrants are increasingly falling into poverty.  相似文献

This article reviews the legal standards and theeconomics of pass-through to indirect purchasers andillustrates these principles with a case involving ADMin the market for high fructose corn syrup (HFCS).With three assumptions about production technologies,buyers of HFCS experience a 100 percent pass throughof the direct overcharge. The extent of pass throughof the increase by buyers is shown to dependcritically upon the market structure of the purchasingindustry and the shape of the retail demand curve. Flexible demand functional forms are needed to avoidconstraining estimated pass through rates.  相似文献

We study the impact of ultra-fast broadband (UFB) infrastructures on the total factor productivity (TFP) and labor productivity of firms. We use unique balanced panel data for the 2013–2019 period on incorporated firms in Italy. Using the geographical location of the firms, we merge firm-level data with municipality-level information on the diffusion of UFB, which started in 2015. We derive consistent firm-level TFP estimates by adopting a version of the Ackerberg et al.’s (2015) method, which also accounts for firm fixed effects. We then assess the impact of UFB on productivity and deal with the endogeneity of UFB by exploiting the physical distance between each municipality and the closest optical packet backbone node. Our results show an overall positive impact of UFB on productivity. Services companies benefit the most from advanced broadband technologies, as do firms located in the North-West and South of Italy. We further decompose the impact of full-fiber networks from mixed copper-fiber connections and find that the former significantly contribute to enhancing firm productivity. Finally, by exploiting Labor Force Survey data, we provide suggestive evidence that productivity increases from UFB might be related to structural changes at the workforce level.  相似文献

This paper presents a model of investment in which heterogeneous firms choose between new investment and acquisitions. New investment involves purchasing a new plant for an existing variety. Acquisitions involve purchasing a plant and a variety from a selling firm. Using a variable‐elasticity demand system, I show that if varieties within a differentiated industry are imperfect substitutes, mid‐productivity firms invest. As varieties approach perfect substitutability, high‐productivity firms invest. For both cases, within the region of investing firms, the most productive choose acquisitions over new investment. In analyzing firm‐level data from Compustat, I find evidence that supports these predictions.  相似文献

This study investigates the contribution of modern communication infrastructure characterized by high speed broadband access network on the productivity growth, production structure and factor demands for US industries and for the aggregate economy. To evaluate such contribution, we modify the traditional cost function by incorporating communication infrastructure as input in production process in conjunction with other public infrastructures. The network externality and spillover effect of broadband access technology are captured by introducing broadband penetration rate as a shift factor in industry level production function. Empirical results show that the increased use of modern communications infrastructure increases the productivity of all industries with wide variations across industries. Estimated impacts on input demands show that increase in use of communications infrastructure service saves labor and materials and increase the demand for private capital. Finally, aggregate social rate of return on such investment has been estimated for policy implications.  相似文献

The purpose of this paper is to examine the productivity performance of the Canadian life insurance industry. We construct a measure of total factor productivity for life insurance companies and then attempt to determine the main sources of improved productivity during the period 1961–1977 by pooling time-series and cross-section data from 31 firms. We conclude that for the industry as a whole technical progress was by far the most important source of productivity growth, while scale economies, on balance, had a marginally negative impact.  相似文献

Using a unique new cross‐national survey of Japanese and Korean workers, we report the first systematic evidence on the effects on employee voice of High Performance Work Practices (HPWPs) from the two economies that are noted for the wide use of HPWPs. We find for both nations that: (i) workers in firms with HPWPs aimed at creating opportunities for employees to get involved (such as shopfloor committees and small group activities) are indeed more likely to have stronger senses of influence and voice on shopfloor decision making than other workers; (ii) workers whose pay is tied to firm performance are more likely to have a stake in firm performance and hence demand such influence and voice; and (iii) consequently workers in firms with HPWPs are more likely to make frequent suggestions for productivity increase and quality improvement. As such, this paper contributes to a small yet growing new empirical literature that tries to understand the actual process and mechanism through which HPWPs lead to better enterprise performance.  相似文献

Beyond concerns about agricultural productivity growth, issues of land governance have attracted global interest as demand for land acquisition by outsiders has increased rapidly but most of the transfers failed to live up to expectations and instead disrupted local livelihoods. We use the land governance assessment framework to identify key conceptual issues and identify how land governance in 10 African countries compares to global good practice. Results point towards weak protection of rights in practice, large gaps in female land access, and limited outreach and effectiveness of institutions to record rights and adjudicate disputes. We note that programs to improve performance along these lines had significant impact in other contexts, suggesting that efforts to improve land governance will be warranted and should be closely monitored and evaluated in an effort to identify models suited to African conditions and assess their impact and interaction with other factor markets.  相似文献

Adoption of modern technologies in agriculture is crucial for improving productivity and welfare of poor farmers in developing countries. Not much is known about how value chains do (not) affect technology transfer and/or adoption in food chains in developing countries. We analyze farm-level technology adoption in the dairy chain in India, using unique survey data. The dairy chain in India is an important case because the Indian government has promoted development of the dairy sector for its potential for ‘pro-poor’ growth, and because value chain initiatives had strong effects on dairy farm technology in other countries with imperfect markets and growth in demand. We find that despite rapid growth in milk consumption and production, technology adoption in the form of better hygienic practices, better feed and improved livestock was mixed, and low for certain regions and technologies. So far, the role of value chains in the adoption of new technologies seems to be minor.  相似文献

This paper focuses on the operational drivers of labour productivity changes. We consider two sets of drivers: (a) current working practices and (b) changes in working practices through management programs. The relationship between these two sets of drivers and productivity changes are analysed. We also investigate the importance of productivity growth by looking at the impact of labour productivity changes on business performance changes. Finally, the moderating effects of industry and country on the use of drivers of productivity changes are examined. Data from an international survey, IMSS-IV, are used for the analysis.  相似文献

Research Summary: We study how internal agglomeration—geographic clustering of business establishments owned by the same parent company—influences establishment productivity. Using Census microdata on the population of U.S. hotels from 1987-2007, we find that doubling the intensity of internal agglomeration is associated with a productivity increase of about 2% in pre-existing establishments. We consider several mechanisms that may be driving the productivity effect and find evidence consistent with the idea that an economically meaningful component of the productivity effect is due to knowledge transfer between internally agglomerated establishments. We replicate our main findings with Census microdata on the full population of U.S. restaurants from 1987-2007, suggesting that the internal agglomeration effects we document may generalize broadly to other industries with multi-unit firms. Managerial Summary: Internal agglomeration is the geographic clustering of business establishments owned by the same parent company. This paper uses detailed Census data on hotels and restaurants to show how internal agglomeration influences performance. Interestingly, knowledge sharing between owned establishments in the same metropolitan area appears to be a key driver of the internal agglomeration effect.  相似文献

We investigate whether the adoption by workplaces of human resources management (HRM) practices that enhance face‐to‐face communication (FTFC) among employees is associated with productivity gains. The analysis is based on a nationally representative sample of over 500 British trading establishments drawn from the linked 2004 Workplace Employment Relations Survey and Annual Business Inquiry, for which objective measures of labour productivity (value added per employee) are available. We find a positive association between productivity and FTFC in problem‐solving groups, teams and meetings of senior or line managers and employees, provided that FTFC is adopted on a continuous basis. Our finding suggests that British workplaces in the trading sector could increase their productivity by implementing HRM practices in such a way as to enhance knowledge sharing through employees' personal interactions.  相似文献

We introduce asymmetric product differentiation in a model characterized by a linear demand system, endogenous markups and heterogeneous firms (as in Melitz‐Ottaviano [2008]). In particular, a single industry is divided into a number of market segments, each characterized by a different degree of horizontal product differentiation. Such a setup allows us to explain, within a single theoretical framework, the non‐linear relations between firm productivity, size and exporting behavior that have been documented by the empirical literature. The theoretical results are tested empirically by examining the performance of French wine producers operating in market segments characterized by different levels of horizontal product differentiation. Such segments are identified using the official classification of French wines based upon the controlled denomination of origin, i.e., the Appellation d'Origine Contrôlée (AOC) system.  相似文献

Advancements in productivity in the digital economy constitute an important engine for economic growth. What drives productivity dynamics in the information and communication technology (ICT) sector? This study examines the productivity dynamics of ICT firms across countries from the perspective of corporate balance sheets. We study the effects of intangible assets and leverage on productivity growth using firm-level panel data from five industrialized countries. We find that intangible assets positively affect the total factor productivity in the ICT sector. The positive effect of intangible assets on total factor productivity growth is larger for ICT manufacturing firms than for ICT service firms. We also find that leverage has a positive relationship with total factor productivity development in the ICT sector. In addition, our empirical results substantiated that productivity is catching up to the technological frontier. Furthermore, larger firms and/or younger firms generally show higher total factor productivity growth than their peers. Economies of scale are more prominent in the ICT service sector than in the ICT manufacturing sector. Our findings contribute to the understanding of cross-country productivity dynamics in the ICT sector at the firm level in the digital economy.  相似文献
