Micro-foundation for a constant elasticity of substitution production function through mechanization

We consider an increase in the range of capital use as a form of mechanization. A constant elasticity of substitution (CES) production function is dynamically derived from Leontief production functions through the endogenous complementary relationship between capital accumulation and mechanization. This implies that a CES production function can be resolved into technological change that does not involve changes in total factor productivity. Furthermore, using the normalizing procedure of the CES production function developed by de La Grandville [de La Grandville, O., 1989. In quest of the Slutsky diamond. American Economic Review 79, 468–481], we investigate how mechanization is related to the elasticity of substitution in our endogenous growth model.     

The Impact of Public Policies on Innovation and Imitation: The Role of R&D Technology in Growth Models

It has been shown under the assumption of linear R&D technology that a government subsidy to imitative (innovative) R&D decreases (increases) imitative effort but increases (decreases) innovative effort, and that strengthening the enforcement of patent laws leads to a decrease in innovative R&D but to an increase in imitative R&D. By replacing the linear R&D technology with a sufficiently convex R&D technology, we have shown that the counter-intuitive results are reversed. In the case of linear R&D technology, the socially optimal R&D policies and activities are indeterminate, but with convex R&D technology, optimal innovation and imitation subsidies would induce the market to generate socially 'balanced' innovative and imitative activities.     

Environmental taxes in a differentiated mixed duopoly

Beladi and Chao (2006) and Bárcena-Ruiz and Garzón (2006) considered the role of environmental policy on the decision whether to privatize a public firm in different market structures. This paper re-examines whether privatization improves (or deteriorates) the environment in a mixed duopolistic framework with differentiated product and pollution abatement. It is shown that, due to privatization, less attention is paid to pollution abatement by all the firms coupled with less environment taxes levied by the government in a differentiated duopoly, and the environment is more (less) damaged when the product is less (more) substitutable. When the product is highly substitutable, industry profits increase because this softens the intensity of the product market, but social welfare deteriorates accompanied with the path of privatization because the loss of consumer surplus and tax revenue exceeds the increases in profits, even if the environment is less damaged.     

Competition and Competition Policy: Implications of Hong Kong's Reversion to China

The paper explores how Hong Kong's new status as China's Special Administrative Region (SAR) may affect the competitiveness of the industries and the relative position of companies owned by non-Hong Kong investors. The conclusion is that mainland Chinese firms will play an increasingly more important role in Hong Kong's economy and British firms will lose their dominance further. This does not, however, indicate a return to unequal competition in favor of firms from the sovereign country, but the beginning of a period of greater competition by all firms in Hong Kong, whether they be local or non-local. There is a risk that governmental and semi‐governmental corporations of the SAR and other Chinese governments may use their official and semi-official status to tilt the playing field in their favor, but appropriate competition law can address this concern.     

Moving from the lab to the field: Exploring scrutiny and duration effects in lab experiments

The most important issue facing experimental economists is the generalizability of lab results. This letter examines more than 1200 doctor/patient consultations, in which scrutiny and duration of treatment were varied. We show that scrutiny has an important but short-lived effect.     

A flexible dynamic model of multiproduct technology for the West German economy

This paper tests symmetry and negativity of the Slutsky matrix for a system of demand functions derived from an aggregate model of multi product technology within a flexible dynamic framework. The model considers three inputs and three outputs, including imports and exports of intermediate goods. We derive a static demand model from a trans log cost function and specify the data generation process by a stationary ARX (1, 1) model. Results based on West German quarterly data indicate that the integrability conditions are not rejected when imposed on the ARX (1, 1) model, whereas they are rejected for all the less general dynamic models considered.     

Who's in charge here? Co‐CEOs,power gaps,and firm performance

At the pinnacles of organizations, comparative tests of unity of command and shared command are nearly impossible because only one individual sits atop most organizations. In organizations led by co‐CEOs, however, such a test is possible because co‐CEOs can truly share power. But do they? Our research pits the unity‐of‐command principle against the shared‐command principle and finds overall support for the former, even within the co‐CEO context. Our sample of 71 co‐CEO pairs at publicly traded U.S. firms shows that increasing power gaps between co‐CEOs are positively associated with firm performance. This positive association wanes and turns negative, however, as power gaps become very large. We conclude that whatever benefits the co‐CEO structure might offer likely lie outside the shared command paradigm. Copyright © 2014 John Wiley & Sons, Ltd.     

Moderately thin advertising models are optimal,most of the time: Moderating the quadratic effect of model body size on ad attitude by fashion leadership

The authors hypothesize and find that an advertising model’s body size has an inverted U-shaped relationship with ad attitude in the apparel product category, in which moderately thin advertising models are optimal. They assess the moderating effect of consumers’ fashion leadership on this quadratic relationship, proposing that this moderation may shift the optimum and/or create a flatter inverted U-shape. In the empirical studies, the authors find both types of moderation may occur and that there may be conditions under which slightly larger, intermediate sized models are most effective for fashion followers and that under other conditions model body size seems to be irrelevant for fashion leaders. As expected, the authors find a positive effect of ad attitude on brand attitude and purchase intentions.     

The Practical Application of Discounted Cash Flow to Plant Purchase Using an Integrated Suite of Computer Programs

This paper describes the problems of using DCF techniques for machine tool evaluation. It is shown that many of the technical and financial assumptions traditionally made are erroneous. However, the use of specially devised computer programs allows these problems to be overcome, with the result that the output from the program reveals how previous authors, by using incorrect methodologies, have seriously understated the financial benefits of investing in advanced technology. The paper discusses the difficulties normally experienced when trying to apply DCF principles, and it is shown how these difficulties are alleviated by the use of a correctly structured program.
