We present field evidence concerning experienced bidders that supports the linkage principle—specifically, the prediction that in affiliated‐values auction environments the expected revenues generated at open‐outcry, ascending‐bid auctions are higher than those under auction formats that reveal less information to participants. Using field data from a large seller of automobiles who experimented with different selling formats, we have found that average revenues were significantly higher under an English auction than under a dynamic Internet auction format that revealed less information to bidders.  相似文献

Small-scale fisheries in developing countries are often perceived as being a low-productivity and backward informal sector. As a result they are rarely considered in poverty reduction programmes and rural development planning. In this paper, we investigate the dual role of fish as a food and cash crop through data collected in river fisheries in Democratic Republic of Congo (DRC). Fishing in this very remote rural region of DRC is operated both by men and women, as part of a household multiple activity livelihood strategy. The data shows that poor households rely heavily on fishing for their supply of protein-rich food, in particular through women’s subsistence catches. Fishing also appears to be the main source of cash-income for the majority of households, including local farmers. Based on these findings and a review of the literature, the paper argues that small-scale fisheries can play a fundamental role in local economies, especially in remote rural areas where they strengthen significantly the livelihoods of people through their role in both food security and cash-income generation.  相似文献

We discuss the importance of patenting to the venture capital investor in high‐technology firms. While literature suggests that patenting will have an impact on the nature and level of investment, the investors themselves are keen to suggest otherwise. We investigate this issue by the use of new primary‐source empirical data, gathered by fieldwork methods. Our results help explain a link between the existence of patenting and the level of investment made. We further support our analysis with illuminating quotes from investors currently active in the field.  相似文献

With the increasing complexity of supply chains in aerospace manufacturing, simulation has become a powerful tool to assess performance. Conventional simulation models are constructed by experts, limiting their usefulness for non-experts. Here, the concept of data-driven simulation is used, where the simulation model is constructed automatically using input data from company IT systems. The paper describes the concept and operation of a supply-chain model builder that has been developed. An example model is provided from the civil aerospace sector. The study shows that data-driven simulation can be useful to support the design and improvement of supply chains. The nature of the conceptual model, model verification and validation in data-driven simulations are discussed. Data-driven simulation is not a replacement for general-purpose simulation tools, but an adjunct valuable in certain circumstances. It can allow a variety of scenarios to be explored relatively quickly without a high level of simulation expertise.  相似文献

Why are some firms more effective than others at addressing stakeholder concerns? Conventional stakeholder theories focus on variables in the external environment and cannot adequately explain variance across firms operating in the same context. Our matched‐pair study of eight global corporations goes inside the firm and investigates the role of managerial cognition on corporate attention to stakeholders. We find that top management's conceptualization of the firm's relationship with society—which we name enterprise logic—prompts distinct foci of attention and potentially constrains how well a single firm can simultaneously attend to multiple stakeholders. These findings highlight the value of an ‘inside‐out’ perspective, centered on managerial cognition, in explaining why some firms address stakeholder concerns more effectively than their peers.

Based on the examination of 239 “best products” (all those on Business Week's annual lists from the past decade), this article tests and validates a conceptual framework identifying six ways in which new products open new markets and/or encroach on original products. Three of these six scenarios involve high‐end encroachment (the new product first opens a new high‐end market, or enters at the high end of an existing market, and then diffuses down‐market), and three scenarios involve low‐end encroachment (encroachment starts at the low end, followed by diffusion up‐market). As illustrated in a 2 × 3 matrix, high‐end encroachment ensues when the new product enhances performance with regard to the market's core attribute (low‐end encroachment ensues when this performance is diminished). The three high‐end sub‐types and three low‐end sub‐types are determined by the strength of performance along an ancillary attribute dimension. If the ancillary attribute performance is week, then the encroachment of the new product on the old market is immediate (corresponding to immediate high‐end encroachment and immediate low‐end encroachment, respectively). If the ancillary performance is moderate, then the new product expands the market at the high or low end (corresponding to new‐attribute high‐end encroachment and fringe‐market low‐end encroachment, respectively). If the ancillary performance is strong, then the new product first opens an entirely new market at the high or low end (corresponding to new‐market high‐end encroachment and detached‐market low‐end encroachment, respectively). The reliability and comprehensiveness of the encroachment framework is tested by asking a panel of eight judges to categorize each of the 239 products. Results show inter‐judge reliability of 98%, with all products falling within one of the six encroachment categories. Each of the encroachment types has unique implications on product positioning and pricing, as further discussed in the paper. Thus the model helps firms identify and analyze the various possible strategies that they might choose from when introducing new products.  相似文献

In this paper, examination of the possibility of a ‘double marginalization’ problem existing in the Korean telecommunication industry is conducted and suggestions are made for the provision of a new scheme to eliminate this possibility by changing the pricing system for fixed-to-mobile calls. Based on five key economic characteristics in the Korean mobile market, a simple model for double marginalization in the telecommunication market is introduced. Evidence was found to suggest that a double marginalization problem is likely to exist within Korea's telecommunication industry as it is presently structured, and that this problem is further likely to have an adverse effect on the industry by inflating the price of fixed-to-mobile calls. Two alternatives are proposed to effectively remedy this double marginalization issue. It is also shown that prices of fixed-to-mobile calls could be lowered by changing the caller pays principle into a receiver pays principle.  相似文献

While much research indicates that organizational processes are learned from experiences, surprisingly little is known about what is actually learned. Using a novel method to measure explicit learning, we track the learned content of six technology‐based ventures from three diverse countries as they internationalize. The emergent theoretical framework indicates that firms learn heuristics. These heuristics have a common structure centered on opportunity capture and are learned in a specific developmental order. This results in a deliberately small, yet increasingly strategic, portfolio of heuristics. Broadly, we contribute to the psychological foundations of strategy by highlighting the rationality of heuristics as strategy, capability creation as the cognitive transition from novice to expert heuristics, and simplification cycling as a critical dynamic capability for sustaining competitive advantage.

The Canadian example suggests that recent shifts in communication policy frameworks should be understood as a transformation in how technology is organized politically, and not simply as a policy reaction to technological innovation. The process is tracked chronologically in three sections: institutional renewal (1993–1994); accelerated vertical slippage between national, regional and global policy levels (1995–1996); and horizontal dispersal of communication policy into new other sectors (1997). Across these stages, a series of convergences characterized by increased fluidity between territorial as well as sectoral jurisdictions are discussed; implications for the understanding of communication policy frameworks within the context of the “information society” project are identified.  相似文献

It is widely believed that work‐related training increases a worker's probability of moving up the job‐quality ladder. This is usually couched in terms of effects on wages, but it has also been argued that training increases the probability of moving from non‐permanent forms of employment to more permanent employment. This hypothesis is tested using nationally representative panel data for Australia, a country where the incidence of non‐permanent employment, and especially casual employment, is high by international standards. While a positive association between participation in work‐related training and the subsequent probability of moving from either casual or fixed‐term contract employment to permanent employment is observed among men, this is shown to be driven not by a causal impact of training on transitions but by differences between those who do and do not receive training, that is selection bias.  相似文献

Contestability in local banking markets is tested using a structure-performance (S-P) model. OLS and TSLS tests using a 38 state sample of 5,396 banks in 1,474 markets reveal a positive concentration-profitability relationship. This implies that local banking markets are not contestable. However, tests for each state separately show that the S-P relationship exists only in approximately one-fifth of states. F-tests indicate that using a national pooled sample is inappropriate. The results suggest that market structure, including entry conditions, affect performance, consequently the theory of potential competition is more relevant than contestability theory. However, generalizations may be inaccurate.  相似文献

The recent privatization of state‐owned enterprises in the Czech Republic forms a natural experiment to test and compare the predictive ability of the resource‐based view (RBV) against the market‐based view (MBV) under conditions of great change. It has been recognized in the literature that, under normal stable circumstances, a firm's internal resources and its external market power are fundamentally intertwined. Consequently, it is difficult to identify the relative roles of these two theories in explaining expected firm performance and firm value. However, when market conditions are in a state of flux, as in the case of the Czech Republic in 1992, we expect the firm's resources to be the primary determinants of firm value. In order to test this notion, an RBV model was developed, based on a set of firm features reflecting the rare and valuable ability to compete in the emerging capitalistic economy (as opposed to the currently prevailing bureaucratically planned economy). A contrasting MBV model was also developed, highlighting the role of market power in this regard. These models were assessed in a cross‐sectional sample of 988 Czech firms undergoing privatization. The empirical findings show that the RBV‐driven variables are remarkably better at explaining share values of Czech firms in the period of privatization than MBV‐driven variables. These results underscore the role of firm resources as a primary determinant of firm value in rapidly changing environments. Copyright © 2003 John Wiley & Sons, Ltd.  相似文献

This paper reports residential real estate price indexes computed from the Standard Metropolitan Statistical Area (SMSA) Annual Housing Survey (AHS) for the 1974 through 1983 period. During this ten-year period, the U.S. Bureau of the Census conducted detailed surveys of the housing stock in sixty metropolitan areas in a three to four year cycle. This information is used to compute tenure specific hedonic housing price indexes for: (1) the entire metropolitan housing market; (2) separately for properties located in the central city and in the suburbs (whenever central city locations are identified); and (3) for three points in the dwelling quality distribution-for substandard housing (using the definition employed by the U.S. Department of Housing and Urban Development), for new housing (housing less than three years old and not substandard), and for existing standard quality housing (everything else). In addition, the hedonic prices reported here are adjusted for the finite sample bias introduced when taking the exponential of a lognormally distributed random variable.  相似文献

The paper reports the actions taken by a large Swedish information technology business to repair defects in the production of system software. Typical problems were late delivery, poor maintainability, lack of documentation. The approach taken to remove the defects consisted in introducing into software production the time- and specification-oriented culture of the factory.
Software writing had usually been delegated to more or less autonomous individuals inside R&D, with the result that expertize was often unrecorded, residing in those individuals' brains, procedures were poorly documented, cross-fertilization with other projects was minimal and lead times were long. The authors identify three reasons for this situation: management ignorance of how the design process operates; professional exclusiveness of design staff; reluctance of managers to exercise supervision over a design engineer's daily tasks.
The solution was to differentiate and rationally define jobs within the design function, set up a flat managerial structure overseeing a group of integrated teams each consisting of a senior system designer plus a junior designer leading four semi-skilled technicians, introduce a well-defined work-flow organization, make use of quality circles, install review procedures, undertake leadership and interpersonal skill training, and take measures to ensure effective communication in all directions.
The new approach has partly been successfully operated for several years. The paper concludes with a discussion of some of the positive and negative lessons which have been learnt during the implementation.  相似文献

This study sought to measure the economic consequences of reduced expenditure on specific sections of the UK National Measurement System (NMS), part of the state-funded technological infrastructure. A method was developed which can be adapted to any publicly or privately financed R&D of which the benefits and cost-effectiveness are unclear or contested.
The recent interactions between the NMS and industry were investigated empirically. Five mechanisms were found to account for the majority of instances of successful value creation. Several case studies of each mechanism were collected, illustrating their existence beyond reasonable doubt.
Each of the cut projects would have been expected to have encouraged growth and profitability in identified sectors of the economy through one or more of these five mechanisms. The effects of the cuts were modelled over 30 years. Compared to the costs of the cut projects projected over the same period, the benefits to the economy were predicted to exceed the costs.  相似文献

This paper features a number of enablers and barriers for the successful introduction of mobile work initiatives. Information and communication technology-enabled mobile work environments are an emerging phenomenon in Europe. On the basis of current theory and the empirical analysis of five selected case studies from a large European research project both facilitating factors and possible obstructions are illustrated and discussed.  相似文献

We use US county‐level data on employment and earnings in the restaurant‐and‐bar sector to evaluate the impact of minimum‐wage changes in low‐wage labour markets. Our estimated models are consistent with a simple competitive model in which supply‐and‐demand factors affect both the equilibrium outcome and the probability of the minimum wage being binding. Our evidence does not suggest that minimum wages reduce employment once controls for trends in county‐level sectoral employment are incorporated. Rather, employment appears to exhibit an independent downward trend in states that have increased their minimum wages relative to states that have not, thereby predisposing estimates towards reporting negative outcomes.  相似文献

Previous literature has studied telework practices predominantly from the employees' perspective rather than exploring its use at the firm level. With the objective of contributing to reducing this research gap, the relationship between firms' adoption of telework and the firms' technological, organisational and environmental contexts is explored. Data were obtained from a survey conducted between 2005 and 2009 on a sample of 1,134 Italian firms in the Piedmont region. The results show an overall increase in the diffusion of telework primarily attributable to a rise in the adoption of ‘mobile’ work rather than home‐based forms of telework. The results also show that firms that had previously adopted information systems supporting core business processes and knowledge management were more inclined to adopt telework. Telework arrangements were more widely diffused among firms facing a growing and geographically dispersed market demand, and also in the contexts of higher levels of human capital and lower capital intensity.  相似文献

Research on the topic of liquidity has greatly benefited from the improved availability of data. Researchers have addressed questions regarding the factors that influence bid–ask spreads and the relationship between spreads and risk, return and liquidity. Intraday data have been used to measure the effective spread, and researchers have been able to refine the concepts of liquidity to include the price impact of transactions on a trade-by-trade analysis. The growth in the creation of tax-transparent securities has greatly enhanced the visibility of securitized real estate, and has naturally led to the question of whether the increased visibility of real estate has caused market liquidity to change. Although the growth in the public market for securitized real estate has occurred in international markets, it has not been accompanied by universal publication of transaction data. Therefore, this article develops an aggregate daily data-based test for liquidity and applies the test to U.S. data in order to check for consistency with the results of prior intraday analysis. If the two approaches produce similar results, we can apply the same technique to markets in which less detailed data are available and offer conclusions on the liquidity of a wider set of markets.  相似文献
