In this note we incorporate the effect of inflation variability on the demand for money in Pakistan. It is found that this variable has a significant impact on money demand function. Our results are similar to those of Klein while they differ with Blejer. 相似文献

A blood-bank inventory system has been analysed viewing it as an inventory-hank system where the demand forecasting forms a part of the inventory model. A simulation model incorporating the “desired-beginning-inventory-level” policy has been used for the analysis of system-performance. Optimal inventory policy-guidelines have been suggested for a hospital blood-bank using blood shortage and blood out-dating as the two important components of the measure of effectiveness. Numerical results have been given. 相似文献

After her independence in 1971, the economic relations between Bangladesh and the European socialist countries developed to a greater extent than before. But the socialist countries still remain relatively small trading partners of Bangladesh. Their share in the total aid received by the heavily aid-dependent Bangladesh has also not been very great. It is not possible to arrive at any precise estimate of the terms of trade and aid between Bangladesh and the socialist countries, but some rudimentary measurements show that they are unlikely to have been very different from those between Bangladesh and the rest of the world. 相似文献

We report a generalization of Aumann's (1966) existence theorem to economies without ordered preferences and with externalities in consumption. Our work can alternatively be viewed as a generalization of the Shafer–Sonnenschein (1975) theorem to economies with a continuum of agents. 相似文献

A comprehensive macroeconomic adjustment program is expectedto have the following objectives: a sustainable current accountposition, a stable and high rate of economic growth that wouldallow for a steady rise in per capita consumption, a reducedrate of inflation, and a manageable level of foreign debt. Thepackage designed to meet these objectives would typically includepolicy measures that simultatenously restrain aggregate demandand increase the availability of resources. These policies maybe grouped as follows: demand-management policies, structuralpolicies, exchange rate policies, and external financing policies.This article describes how these policies can be expected toachieve the goal of macroeconomic adjustment. The focus is primarilyon the theoretical and empirical links between policy instrumentsand ultimate objectives. An examination of these links is necessarybefore issues of the appropriate mix of demand-management, structural,exchange rate, and external policies, and the sequencing ofthese policies in a program, can be properly addressed. 相似文献

The problem of allocating the sample numbers to the strata in multivariate stratified surveys, where, apart from the cost involved in enumerating the selected individuals in the sample, there is an overhead cost associated with each stratum, has been formulated as a non-linear programming problem. The variances of the posterior distributions of the means of various characters are put to restraints and the total cost is minimized. The main problem is broken into subproblems for each of which the objective function turns out to be convex. When the number of subproblems happens to be large an approach has been indicated for obtaining an approximate solution by solving only a small number of subproblems. 相似文献

This paper investigates the mediating effect of learning intent in transforming local suppliers’ potential absorptive capacity into realized absorptive capacity and its impact on exploitative and exploratory innovation. Using survey data from 155 auto parts manufacturers in Pakistan, we find that local firms’ realized absorptive capacity enables them to develop both exploitative and exploratory innovations. The findings further suggest that local suppliers’ learning intent mediates the relationship between potential and realized absorptive capacity which in turn lead to both types of innovation. In the context of the emerging economy of Pakistan, local suppliers’ absorptive capacity is found to be critically important in spurring exploitative and exploratory innovation, but learning intent enables realized absorptive capacity and thus in conjunction with realized absorptive capacity supports innovation. Consequently, there would be a strong case for policy intervention to assist emerging economy firms in building their absorptive capacity and strengthening their learning intent as a route for promoting innovation and improving their value added position in the global value chains of multinational enterprises. 相似文献

The rise of the digital economy provides firms across the globe with unique business opportunities. Companies such as Facebook, Alibaba, and Uber are competing in a new multi-sided platform world; the primary focus of these firms, from their inception, is to provide digital infrastructure, information and technology—intangible assets that enable direct interaction or value creation across platforms by linking different user group and complementors, often at the international level. Building on data drawn from multinational multisided Platform corporations (MMPCs) operating in China, we combine insights from internalization theory and network effects in understanding the value creation of such firms. We explore the boundaries of these new “breed” of MNEs in exploiting firm-specific advantages (FSAs) and in creating new knowledge between headquarters and subsidiaries. The findings suggest that internalization theory needs to shift its focus from the ‘boundaries of the firm’ to the ‘boundaries of the local network’. By integrating their internal and external networks of knowledge in adapting their business models in host markets, this new breed of MNEs is more likely than the traditional one to gain a sustainable competitive advantage in the new information age. 相似文献
