Labour productivity, economies of scale and opening time in large retail establishments

Differences in labour productivity are dealt with for large French retail establishments. Influences of scale, weekly opening time, assortment composition, wage rate and share of counter service are considered. The relationship used is a result of analyses in the field of small retail establishments

Productivity in Small Business: an analysis using African data

Labor and floorspace cost functions are derived for small business trade. Relationships are proposed between average volume of labor or average floorspace per establishment on the one hand, and average size per establishment, average rental paid, percentage selling space, and indicators of business type and location on the other. Promising estimation results are reported using South African data of 1979/1980. The method however is not restricted to the South African case. A productivity business support system can be developed providing productivity standards for any area in the small (service) business. An analysis similar to the one presented here, but relating to the area in question, should precede the development of such a system

Entrepreneurship, Economic Growth and Policy in Emerging Economies

Entrepreneurship has emerged as an important element in the organization of economies. This emergence did not occur simultaneously in all developed countries. Differences in growth rates are often attributed to differences in the speed with which countries embrace entrepreneurial energy. This led to the political mandate to promote entrepreneurship. Hence, a clear and organized view is needed of what the determinants and consequences of entrepreneurship are. The present contribution tries to provide this view with a particular view on emerging economies. Entrepreneurship, its drivers and its consequences can be best understood using the model of the Entrepreneurial Economy which explains the functioning of the modern economy. This model differs from that of the earlier Managed Economy. Policies in emerging economies should aim at combining the two models

Parallel semiconductor device simulation: from power to 'atomistic' devices

This paper discusses various aspects of the parallel simulation of semiconductor devices on mesh connected MIMD platforms with distributed memory and a message passing programming paradigm. We describe the spatial domain decomposition approach adopted in the simulation of various devices, the generation of structured topologically rectangular 2D and 3D finite element grids and the optimisation of their partitioning using simulated annealing techniques. The development of efficient and scalable parallel solvers is a central issue of parallel simulations and the design of parallel SOR, conjugate gradient and multigrid solvers is discussed. The domain decomposition approach is illustrated in examples ranging from `atomistic' simulation of decanano MOSFETs to simulation of power IGBTs rated for 1000 V

Impact of random dopant induced fluctuations on sub-15nm UTB SOI 6T SRAM cells

The CMOS scaling increases the impact of intrinsic parameter fluctuation on the yield and functionality of SRAM. A statistical circuit simulation framework which can fully capture intrinsic parameter fluctuation information into the compact model has been developed. The impact of discrete random dopants in the source and drain regions on 6T SRAM cells has been investigated for well scaled ultra thin body (UTB) SOI MOSFETs with physical channel length in the range of 10nm to 5nm

UTB SOI SRAM cell stability under the influence of intrinsic parameter fluctuation

Intrinsic parameter fluctuations steadily increases with CMOS technology scaling. Around the 90nm technology node, such fluctuations will eliminate much of the available noise margin in SRAM based on conventional MOSFETs. Ultra thin body (UTB) SOI MOSFETs are expected to replace conventional MOSFETs for integrated memory applications due to superior electrostatic integrity and better resistant to some of the sources of intrinsic parameter fluctuations. To fully realise the performance benefits of UTB SOI based SRAM cells a statistical circuit simulation methodology which can fully capture intrinsic parameter fluctuation information into the compact model is developed. The impact on 6T SRAM static noise margin characteristics of discrete random dopants in the source/drain regions and body-thickness variations has been investigated for well scaled devices with physical channel length in the range of 10nm to 5nm. A comparison with the behaviour of a 6T SRAM based on a conventional 35nm MOSFET is also presented

Introduction: economic performance and small business

This paper introduces the special issue of Small business Economics on Performance. The concept of economic performance refers to the degree to which society's resources are being used as efficiently as possible. Where the field of industrial organization has emphasized the influence of market concentration on economic performance, the papers of this special issue zoom in on the link between firm size and economic performance

De Ondernemerschapseconomie

De overgang van de managed naar de entrepreneurial economie wordt aangetoond met behulp van de relatie tussen de TEA-index (Total Entrepreneurial Activity) en het ontwikkelingsniveau van een economie. Vervolgens wordt met behulp van veertien dimensies het onderscheid tussen de twee economieën besproken

What's New About the New Economy? Sources of growth in the managed and entrepreneurial economies

The purpose of this paper is to document the fundamental shift that is taking place in OECD countries. This shift is from the managed economy to the entrepreneurial economy. While politicians and policy makers have made a plea for guidance in the era of entrepreneurship, scholars have been slow to respond. This paper attempts to make a first step identifying and articulating these differences. We do this by contrasting the most fundamental elements of the newly emerging entrepreneurial economy with those of the managed economy. We identify fourteen trade-offs confronting these two polar worlds. The common thread throughout these trade-offs is the increased role of new and small enterprises in the entrepreneurial economy. A particular emphasis is placed on changes in economic policy demanded by the entrepreneurial economy vis-?-vis the managed economy

A Note on Entrepreneurship, Small Business and Economic Growth

The aim of the present short paper is to show that since the 1970s the world has changed considerably, and that this change has had consequences for the current policy debate on the determinants of economic growth. Our paper deals with some aspects of the recent scientific literature on the relation between entrepreneurship and small business, on the one hand, and economic growth, on the other. In particular, it gives a summary of some work of the EIM/CASBEC research group in the Netherlands. It refers to scientific analyses showing that countries that are lagging behind in the process of restructuring will pay a penalty in terms of forgone growth. It also pays attention to the Global Entrepreneurship Monitor (GEM), a new and large multinational project focusing on the collection and analysis of internationally comparable data on the rate of entrepreneurial activity
