The paper extends Manning's model on education and balanced growth to include labour immigration. Each immigration unit is assumed to consist of one skilled worker and some unskilled members. The optimal immigration policy which maximizes the per capita steady-state consumption of the host country is derived. We show that optimal immigration policy can reduce the steady-state skilled labour ratio. More interesting still, contrary to the widespread belief that immigration of skilled workers hurts local skilled workers, it is the unskilled local workers whose interests are threatened by optimal immigration policy.  相似文献

This article investigates the change in operating performance of firms as they make the transition from private to public ownership. A significant decline in operating performance subsequent to the initial public offering (IPO) is found. Additionally, there is a significant positive relation between post-IPO operating performance and equity retention by the original entrepreneurs, but no relation between post-IPO operating performance and the level of initial underpricing. Post-issue declines in the market-to-book ratio, price/earnings ratio, and earnings per share are also documented.  相似文献

This paper compares the approximation capabilities of the minflex-Laurents translog and minflex generalized Leontief cost functions with their translog and generalized Leontief counterparts in Monte Carlo experiments. The minflex Laurent specifications generally provided closer approximations to underlying technical and economic parameters. Imposition of nonlinear restrictions on some of the parameters of the minflex Laurent models yielded measurable improvement in estimated elasticities of substitutions, returns to scale, and rates of technical change.The refereeing process of this paper was handled through E. Appelbaum.  相似文献

Offshoring in the New Global Political Economy   总被引:5,自引:1,他引:4  
abstract    This essay challenges claims by economists and management scholars that 'offshoring' is simply another form of trade with mutual benefits. I argue that reducing wages through offshoring leads to wealth creation for shareholders but not necessarily for countries and employees, and that many displaced workers have difficulty 'trading up' to higher skilled jobs. Offshoring is a new phenomenon that entails the organizational and technological ability to relocate specific tasks and coordinate a geographically dispersed network of activities. It decouples the linkages between economic value creation and geographic location. The result is the creation of global commodity markets for particular skills and a shift in the balance of market power among firms, workers, and countries.  相似文献

The 1992–93 recession in the western states of Germany has been attributed, in substantial measure, to the macroeconomic consequences of policies to finance unification. Studies of the costs of unification have not attempted to measure the burden of the recession. We estimate a dynamic, panel model of household incomes using data from the German Socio-Economic Panel (GSOEP) and use it to forecast what these incomes would have been in 1992–94 without a recession. Using a ratio of actual to forecast incomes, we compare the relative burden of the recession across households. Our findings suggest that western households below the median income bore the brunt of the combined impact of unification and the recession of 1992–93.

For many if not most publicly traded companies, acquisition capabilities remain a critical component of sustainable longterm growth and profitability. And even as investors press companies to return excess capital through dividends and stock buybacks, the market continues to assign premium valuations to companies that earn above-average returns through a combination of internal investment and judicious acquisition spending.
This article begins by describing major challenges facing acquirers in the current business and regulatory environment. Then, after showing how M&A can be used to address strategic goals, the authors identify key elements in the M&A strategies of three highly successful companies: General Electric, Danaher, and Illinois Tool Works.  相似文献

The number of firms using alliances as part of their corporate venturing or market entry strategies has surged over the past decade. Three common reasons cited for pursuing alliances are technology convergence, market access and alliance partners' complementary resources. This paper contrasts the alliance strategies of HP and IBM, two major competitors in electronic services (i.e. Internet-based 'e- service') businesses, using the Familiarity Matrix as a display tool to portray the strategies. Whereas the HP strategy is to attempt to establish its technology infrastructure as the standard e-services infrastructure on the Internet, IBM aims to position its IBM Global Services, rather than its technology, at the center of this ecosystem.  相似文献

Managers and scholars emphasize the importance of inter‐departmental integration to successful product development and emphasize the importance of product development capabilities to firm performance. Interdepartmental integration can increase shared knowledge; this in turn can reduce the severity and incidence of seemingly unnecessary and costly mistakes leading to more efficient and effective product development. This paper examines the sources of shared knowledge problems across functional and product‐based groups. Using interviews, product development plans, and time‐sheet data, we look at the underlying factors behind two sources of knowledge sharing problems: (1) a serial product development process (i.e. little or no face‐to‐face communications) and (2) ineffective use of integrating mechanisms because of sticky knowledge. For each problem source, we find two key causal factors. We discuss the problems, their factors, and the implications for management and theory.  相似文献
