Outsourcing of non-core activities is nowadays a common business strategy. Declining transaction and transportation costs caused by the advent of Information and Communication Technology are a potentially important driving force behind this development. This paper provides a theoretical framework for analysing a firm's incentive to follow such a strategy of outsourcing and its consequences for macroeconomic variables like growth and product variety. We divide production activities into core and non-core activities. Non-core activities can be performed within the firm or can be mediated by the market. We derive conditions under which outsourcing occurs, and under which outsourcing is socially desirable. These conditions do not necessarily coincide. Outsourcing may hence be a profitable strategy for firms, while it is socially suboptimal. Crucial parameters in the model are the relative scale of core versus non-core activities, management costs, transaction costs and love for variety of consumers.  相似文献

We estimate a target zone model for three ERM exchange rates for 1983–6 and 1987–91 by the method of simulated moments, taking account of the continuous time specification by using daily data with the interruptions of holidays and weekends. Specification tests are unable to reject the model. The estimates imply, however, an essentially linear relationship between the exchange rate and the fundamentals, with a very limited 'honeymoon effect'. Using Monte Carlo simulations, calibrated on the estimates, we find that standard tests for mean reversion of the exchange rate would largely reject the target zone model when, in fact, it held.  相似文献

This paper presents further evidence on the empirical regularity known as the "45-degree rule." Income and price elasticities of trade are estimated for 21 countries in a cointegration framework. More specifically, the autoregressive distributed lag (ARDL) modeling approach and the DOLS procedure are adopted to estimate the long-run structure. The empirical results confirm the existence of a systematic relationship between growth rates and income elasticity estimates: faster growing economies have high income elasticities of demand for their exports but lower import elasticities, which implies that faster growth can be observed without any marked secular trend in real exchange rates.  相似文献

ABSTRACT: Insurance regulators operate in an environment in which resources are scarce and issues are most often complex and not salient to affected persons. Consequently, regulatory agencies, such as the Pension Benefit Guaranty Corporation (PBGC), need to use resources efficiently by making issues salient and not complex if regulatory goals are to be attained. To further its goal of full funding of defined benefit pension plans, the PBGC annually published a list of the Top Fifty Companies With the Largest Underfunded Pension Liability (LIST). This article investigates the issue of the economic effects of pension plan disclosure by measuring the share price response of the companies included on the LIST; then policy implications are drawn. The event study findings show that, on average, publication of the LIST did not have a negative effect on firm value. However, cross-sectional analysis provides some support for the contention that publication of the LIST had an economic cost on LISTed firms. The authors' results show that the value of large firms on the PBGC's list is less negatively affected at arrival (ARRIVAL) than smaller LISTed firms. Conversely, when firms leave the list (DEPARTURE), the value of large growth-oriented firms is more negatively affected than the value of other firms that reduce their unfunded pension liability. From a policy perspective, as hypothesized by Meier (1991), the PBGC used its scarce resources effectively by publishing the LIST. The issue of unfunded pension liability became less complex and more salient to interested parties. Consequently, consumer groups and political elites provided their support to further the regulatory agency's stated goal, which was the full funding of defined benefit pension plans. Furthermore, increased awareness of the underfunding problem contributed to the passage of the Retirement Protection Act of 1994.  相似文献
