This paper develops and tests a new model for multiple-unit adoptions of durable goods based on the diffusion modeling tradition. Multiple-unit adoptions are a major component of sales for many consumer durable product categories. For instance, sales of multiple-unit adoptions for televisions have been higher than both first adoptions and replacement purchases since 1977, while for automobiles, they have represented more than 20% of sales since 1966 in Australia. The structural drivers of multiple-unit adoptions are quite different from either first purchase or replacement purchase. Hence, identifying and modeling the multiple-unit component of sales is important for aggregate sales forecasts. Moreover, consumer requirements for additional units of a product are likely to be considerably different than for the other components of sales (first purchases and replacement purchases). As such, the ratio of the first, multiple, and replacement sales components will strongly influence the product mix requirements of the market.

While forecasting and influencing multiple-unit sales are an important managerial issue, very little attention has been given to multiple-unit ownership in the diffusion modeling literature. The only model available was developed for the purpose of modeling relatively short-term behavior of multiple-unit adoptions, rather than the longer-term pattern of sales. We propose a model of multiple-unit adoptions as a diffusion process.

We apply the model to both color television and automobiles. Analysis of the model's long-term fit and forecasts in these applications provide support for the structure of the new model.  相似文献

This article examines the impact of statutory regulation on qualifications and skills in the social care sector in the UK. It draws on various sources and a set of case studies, first carried out in 2003 and replicated in 2008. The analysis shows that the advent of the statutory regime has had a positive effect on the volume of training and qualifications in the sector. However, few organizations have combined training with a broader set of human resource management practices of the kind required for the establishment of a high‐performance work system. This constitutes one of the continuing limits to further skill development. Changes in the regulatory regime risk losing benefits that have been gained.  相似文献

Do shareholders gain when managers disperse corporate resources through activities classified as corporate social responsibility (CSR)? Strategy scholars have recently developed a theoretical model that links such activities to shareholder value when a firm suffers a negative event; we test key portions of this theory of the ‘insurance‐like’ property of CSR activity. We posit that such activity leads to positive attributions from stakeholders, who then temper their negative judgments and sanctions toward firms because of this goodwill. We extend the risk management model by theorizing that some types of CSR activities will be more likely to create goodwill and offer insurance‐like protection than other types. We delineate several firm and event specific characteristics that we expect to influence the link between CSR activities and an insurance effect. We then test our model using an event study of 178 negative legal/regulatory actions against firms throughout the 11 years from 1993–2003. We find that participation in institutional CSR activities—those aimed at a firm's secondary stakeholders or society at large—provides an ‘insurance‐like’ benefit, while participation in technical CSRs—those activities targeting a firm's trading partners—yields no such benefits. We conclude by considering the implications of our findings for future theorizing and research into the economic value of CSR engagement. Copyright © 2008 John Wiley & Sons, Ltd.  相似文献

Establishment of the European Central Bank presents a rare opportunity to define the operations of a central bank without a prior track record. This paper asks what might be learnt from the recent experience of inflation targeting at the Bank of England before the ECB specifies an, as yet undefined, operational target. We consider whether there should be single or multiple targets and which inflation measure should be used, if at all. If inflation is targeted then a forecast of its value becomes the intermediate variable. This raises an issue of transparency and the compensating supply of information necessary to fill the gap, but too much 'openness' can also be problematic. The ECB must be accountable and the contracting approach may be useful although being seen to 'say' and 'do' the same thing is ultimately most important.  相似文献

We present a model of North–South trade with multinational firms and increasing product variety. Firms engage in innovative R&D to develop new product varieties in the North, and foreign affiliates of multinational firms engage in adaptive R&D to learn how to produce product varieties in the South. We find that a shift to stronger protection of intellectual property rights in the South induces foreign affiliates of multinational firms to increase their R&D expenditures, results in a faster rate of technology transfer within multinational firms, and increases long‐run consumer welfare in both regions.  相似文献

We use matched employee–employer data from Britain to assess the influence of disability-specific workplace policies and practices on the earnings of disabled workers. The presence of equal opportunities policies increases the relative wages of disabled workers, but this is partially offset by the negative influence of workplace accommodations.  相似文献

When entering a monetary union, member countries change the nature of their sovereign debt in a fundamental way; that is, they cease to have control over the currency in which their debt is issued. As a result, financial markets can force these countries’ sovereigns into defaulting. This makes the monetary union fragile and vulnerable to changing market sentiments. It also makes it possible that self‐fulfilling multiple equilibria arise. I analyse the implications of this fragility for the governance of the Eurozone. I argue that the role of the European Central Bank as a lender of last resort is crucial in reducing the fragility of the Eurozone. In addition, steps towards a budgetary union are key in structurally strengthening the union.  相似文献

There has been a substantial recent growth in government loan guarantees to ailing firms in the United States. This paper investigates the potential incentive effects of this practice. Using the simplest available two-period model, it is shown that when firms know that loan guarantees may be forthcoming, they may be induced to adopt riskier investments and take on more leverage. These perverse incentive effects imply that the actual loan-guarantees-related contingent liability of the government could be much larger than suspected. Our policy recommendation is that the government either abandon the practice altogether or set up a federal agency that sells loan guarantees to all firms at prices that depend on the riskiness of the firm's assets and its leverage.  相似文献
