Teresa Beckham Gramm 《Review of International Economics》2005,13(4):822-839
Most models of international trade assume extremes of factor mobility between productive uses. From perfectly mobile factors in the Heckscher–Ohlin model, to fixed capital and mobile labor in the Ricardo–Viner–Jones model, factors are assumed to move costlessly or not at all. In reality, factors are neither perfectly mobile nor fixed. This paper considers costs of reallocating factors between industries, deriving a measure of adjustment costs due to factor specificity in a two‐period model of a firm's input allocation decision. The degrees of specificity for labor and capital are then estimated based on data for 15 industries in 16 countries covering eight years. Estimating a system of nonlinear first‐order conditions using a three‐stage least squares technique, I find that recently reallocated factors are indeed less productive. Labor is 14% less productive in the period after reallocation, while capital productivity falls by 43%. Thereafter, capital, unlike labor, moves quickly toward full productivity. 相似文献

Dynamic Seemingly Unrelated Cointegrating Regressions 总被引:4,自引:0,他引:4
We propose the parametric Dynamic Seemingly Unrelated Regression (DSUR) estimator for simultaneous estimation of multiple cointegrating regressions. DSUR is efficient when the equilibrium errors are correlated across equations and is applicable for panel cointegration estimation in environments where the cross section is small relative to the available time series. We study the asymptotic and small sample properties of the DSUR estimator for both heterogeneous and homogeneous cointegrating vectors. We then apply the method to analyse two long-standing problems in international economics. Our first application revisits the estimation of long-run correlations between national investment and national saving. Our second application revisits the question of whether the forward exchange rate is an unbiased predictor of the future spot rate. 相似文献

The purpose of this research was to examine empirically the effects of new product development outcomes on overall firm performance. To do so, first product development and finance literature were connected to develop three testable hypotheses. Next, an event study was conducted in order to explore whether the changes in the stock market valuation of firms are influenced by the outcomes of efforts to develop new products. The pharmaceutical industry was chosen as the empirical context for the present study's analysis largely because the gate‐keeping role played by the Food and Drug Administration (FDA) provides a specific event date on which to focus the event study methodology. As such, this study's events were dates of public announcements of the FDA decisions to approve or to reject the New Drug Applications submitted by the sponsoring firms. Consistent with the efficient market hypothesis, this study's results show that market valuations are responsive strongly and cleanly to the success or failure of new product development efforts. Hence, one of this study's key results suggests that financial markets may be attuned sharply to product development outcomes in publicly traded firms. This study also finds that financial market losses from product development failures were much larger in magnitude than financial market gains from product development successes—indicating an asymmetry in the response of financial markets to the success and failure of new product development efforts. Hence, another implication of this study's results is that managers should factor in a substantial risk premium when considering substantial new development projects. The present study's results also imply that managers should refrain from hyping new products and perhaps even should restrain the enthusiasm that the financial community may build before the product fully is developed. The effect on firm value is severe when expectations about an anticipated new product are not fulfilled. Managers in effect should take care to build reasonable and realistic expectations about potential new products. 相似文献

A comparison of ranking,rating and reservation price measurement in conjoint analysis 总被引:2,自引:1,他引:1
This paper empirically compares the traditional preference measures of ranking and rating in conjoint analysis with a direct monetary measure of product value — reservation prices. Experimental results are as expected. While reservation prices do very well in terms of fit, they are inferior in terms of predicting choice on a holdout sample. In addition, surprisingly little difference is found in the performance of ranks and ratings. 相似文献

This study examines the most valuable sources of new product ideas and the criteria used to screen potential new products in entrepreneurial, high-tech firms. Teresa Pavia explored the practices of 118 small, young, high-tech firms. Her findings complement a variety of existing studies of the new product process in large firms and the few existing studies of the process in entrepreneurial, high-tech firms. The firms participating in this study rely on informal techniques to generate new product ideas. They place heavy reliance on input from their customers and often develop new products in response to problems articulated by these customers. Although the annual strategic plan is not used by most firms as a new product identification tool, it is highly rated by the most successful firms. Successful firms also actively engage in environmental scanning. The majority of the respondents do not use financial measures as a screening criterion, preferring to evaluate new products by "gut feel." However, the firms that have experienced the fastest growth in sales employ financial hurdles for project selection. The educational background of the key GO/NO GO decision-makers was also evaluated. Two thirds of the firms reported having a key decision-maker with an educational background in business. The educational background of the key decision-makers had little impact on the aspects of the new product process studied here. 相似文献

I am honored to have been chosen as the Journal of Product Innovation Management's ( JPIM 's) new book review editor. First and foremost, I want to thank Preston Smith for making the transition an easy one. Preston's experience and insights have helped bring me up the learning curve. His patience was much appreciated.
Second, managing the book review process is certainly more complicated than I had imagined but is fascinating nonetheless. As in the development of any product or service there are many people involved in the creation process, and considerable planning takes place prior to actual publication.
Last but not least is my admiration for our JPIM book reviewers. The care and effort taken to create the quality book reviews that meet JPIM 's high standards requires critical thought and experience in new product development. We will continue to make our book reviews insightful, critical, and practical for you, our readers.

This article stresses the need for today's multinational firms to adopt their own political risk‐assessment and risk‐mitigation strategies. A comparative study of the energy, financial, and automobile sectors illustrates the need for all companies in these sectors to undertake comprehensive risk‐assessment strategies. Risk‐assessment models established by leading multinationals like British Petroleum, Bank of America, and General Motors are examined as examples that other companies in these sectors can build upon. The consistent micropolitical risk variables then lead to a proposed practical framework for examining sector‐specific micropolitical risk. © 2006 Wiley Periodicals, Inc. 相似文献

Off‐farm labour decisions of a sample of Kansas farmers are evaluated. The central question of our analysis pertains to whether 1996 US farm policy reforms may have altered the decisions to work off the farm. The effects of policy decoupling on off‐farm labour are complex: different aspects of policy changes can have opposing effects on off‐farm work decisions. Essentially, this makes this issue an empirical question. Results show that the introduction of fixed, decoupled payments in 1996 might have reduced the likelihood of off‐farm labour participation. However, the new policy environment may have increased farm households’ revealed aversion to risk, motivating a higher participation in non‐farm labour markets. The effects of 1996 policy reforms on farm income variability could have been attenuated by changes in US crop insurance programmes and by an increase in emergency assistance payments towards the end of the 1990s. The reduction in price supports may have increased the motivation for working off the farm. The net effect of the overall reforms on off‐farm work participation is not likely to have been large. 相似文献
