In the literature on economic development and planning, much is made of the problem of ‘choice of technique'—choosing either capital or labour intensive techniques. In this paper the focus is on another aspect of this problem—the choice among capital inputs, the selection of new or second‐hand equipment. As much of the investment in the less developed countries depends on imported machinery, the problem becomes that of making the most efficient use of foreign exchange. The question is relevant as a number of developing countries have imposed prohibitions on the importation of used machinery.
First we examine the theoretical implications of the availability of both new and used machines for the production possibilities and the effects of various trade policies on the selection of production technique. Integrating this question of new versus used machines with investment criteria, we then examine situations in which used machinery might be preferable to new. 相似文献

In 1976, Lockheed Corporation was charged with making secret payments of at least $25 million to Japanese officials during the early 1970s. It was alleged that these payments were made in order to secure aircraft sales contracts with several Japanese airlines. At that time, Lockheed executives claimed that Japanese officials insisted that consideration of Lockheed as a contractor would require advance payments to several government officials. In spite of this claim, Congress passed the Foreign Corrupt Practices Act in 1977 which treats these payments as bribery, rather than extortion, and prohibits them with the threat of criminal penalties. During the last 10 years, Japan has tried and convicted 15 former government officials of bribery and other crimes in the Lockheed affair. This paper assesses the effects of the Foreign Corrupt Practices Act in regulating business conduct, and the validity of the claims by Lockheed and the Japanese officials 10 years later, now that the trials are over. 相似文献

The present article outlines the role of personal, social, and cultural identity in religiously and ethnically motivated terrorism. It is proposed that terrorism represents the confluence of a cultural identity strongly based in collectivism and in fundamentalist adherence to religious or cultural principles, a social identity based in sharp contrasts between one's own group and groups perceived as threats, and a foreclosed and authoritarian sense of personal identity or, less often, a diffused and aimless personal identity. Examples from religious-extremist and ethnic conflicts in which terrorism has been employed are used to illustrate the tenets advanced here. Recommendations for addressing and preventing the threat of terrorism are discussed. 相似文献

It is widely unclear as to whether start-up firms supported by publicly-initiated incubator initiatives have higher survival rates than comparable start-up firms that have not received support by such initiatives. This paper contributes to the underlying discussion by performing a large-scale matched-pairs analysis of the long-term survival of 371 incubator firms (after their graduation) from five German incubators and a control group of 371 comparable non-incubated firms. The analysis covers a 10-year time span. To account for the problem of selection bias, a non-parametric matching approach is applied to identify an appropriate control group. For neither of the five incubator locations, we find statistically significant higher survival probabilities for firms located in incubators compared to firms located outside those incubator organizations. For three incubator locations the analysis reveals statistically significant lower chances of survival for those start-ups receiving support by an incubator. The empirical results, therefore, raise some doubts regarding the impacts of incubation on long-term firm survival. 相似文献

This study was designed to determine the effects of various environmental factors on the deoxyribonucleic acid (DNA) obtained from dental pulp. Extracted teeth were subjected to the following conditions: varying pH (3,7,10); temperature (4 degrees C, 25 degrees C, 37 degrees C, incineration); humidity (20%, 66%, 98%); various types of soil (sand, potting soil, garden soil); seawater; burying the teeth outdoors, and aging (one week to six months). In addition, teeth that had been extracted and held at room temperature for 16 and 19 years were also examined. Following isolation of DNA, the samples were analyzed on yield gels to determine the concentration and integrity of the recovered DNA. Restriction digestion with Pst I was followed by electrophoresis of the generated fragments, Southern transfer to nylon membranes, and hybridization to both human and bacterial probes. It was determined that, aside from soil, the environmental conditions examined did not affect the ability to obtain high-molecular-weight human DNA from dental pulp. Restriction fragment length polymorphic (RFLP) analysis of selected samples was performed. Dental pulp patterns were compared with bloodstain exemplars, revealing matching patterns, although an increase in band-shifting was observed with extended exposure to elevated temperatures. 相似文献

This article will address the legal obligations of employers in non-union settings toward employees who request pregnancy leave, parental or medical leave, workers' compensation leave, and other forms of disability leave. Specifically, this article will address the legal standards set forth under the Pregnancy Discrimination Act, various state pregnancy and family leave acts, workers' compensation retaliatory discharge authority, and the Americans With Disabilities Act of 1990. In addition, this article will provide practical guidance for employers in formulating effective leave policies that provide the maximum amount of operational flexibility while at the same time minimizing the risk of costly and excessive litigation. 相似文献
