On the shape of the single-country and world commodity-substitution and factor-substitution surfaces under conditions of joint production

In recent years trade theorists have completed the task of specifying necessary and sufficient conditions for the single-country and world transformation surfaces to be locally of any assigned degree of flatness. However those conditions are relevant only if the technology is of the no-joint-products type. In the present note we derive necessary and sufficient conditions for the single-country and world transformation surfaces to be of any assigned degree of flatness under conditions of joint production; and we also obtain, as a by-product, necessary and sufficient conditions for the single-country and world equal-product surfaces to be of any assigned degree of flatness.     

提升我国服务贸易竞争力的路径分析

改革开放以来,我国服务贸易发展迅速。但是我国服务贸易总额占世界服务贸易总额比重很小,且服务贸易逆差逐年加大,因此提高我国服务贸易竞争力就显得尤为迫切。本文从对我国服务贸易现状的分析入手,通过对服务贸易竞争力在高级生产要素缺乏,服务水平不高,发展缓慢等问题的分析的基础上,揭示了我国服务贸易竞争力在国内外方面的不足,并在此基础上提出应对策。     

Financing municipal BOOTs in South Africa: The lenders' perspective

South Africa's first build‐own‐operate‐transfer (BOOT) project for municipal services was signed in late December 1998 by the city of Durban and a private project company associated with French conglomerate Vivendi. The project will treat waste water for sale to industrial customers who would otherwise use more expensive potable water in their manufacturing processes. The project structure, with its multiple contracts and supporting agreements, guarantees and complex shareholding relationships, represents a sophisticated analytical challenge for lenders, whose financing will ultimately be at risk in the deal. Development finance institutions, such as the Development Bank of Southern Africa (DBSA), must review such projects in even greater detail because of their mandate to promote sustainable infrastructure development in the region. This article presents the DBSA ‘s analytical perspective on the Durban BOOT project in an effort to capture the complex, innovative and strongly developmental character of what, for South Africa, is a ground‐breaking public‐private partnership project.     

You can't always get what you want: The impact of the UK Jobseeker's Allowance

In 1996 the UK made major changes to its welfare system for the support of the unemployed with the introduction of the Jobseeker's Allowance. This tightened the work search requirements needed for eligibility for benefit. It resulted in large flows out of claimant status, but, this paper concludes, not primarily into employment. The movement out of claimant status was largest for those with low levels of search activity. But, this paper finds no evidence of increased job search activity as a result of this change.     

The power of asymmetric unit root tests under threshold and consistent-threshold estimation

The asymmetric unit root tests of Enders and Granger (Journal of Business and Economic Statistics, 16, 304–11, 1998) are examined using consistent threshold estimation and the original two-step procedure. In contrast to earlier studies, the ability of the tests to jointly reject the unit root and symmetry hypotheses is examined, thus permitting a fuller analysis of the tests' properties. Whilst the threshold autoregressive test is found to have little power in either its consistent or original forms, the consistent momentum-threshold autoregressive test is found to exhibit high power against a range of plausible alternatives when using newly derived critical values.     

Labour Market Trends and Structures in ASEAN and the East Asian NIEs

The paper reviews the literature on labour markets in the region with special emphasis on the impact of economic growth and structural change on employment and wages. It deals with labour supply trends, employment creation outside agriculture (especially export orientated industrialization and new high-tech industries), labour absorption in agriculture, wage differentials and the functioning of rural and urban labour markets.
The creation of efficient and equitable labour market institutions and labour market flexibility have emerged as dominant issues in the NIEs. In the ASEAN-4, because of concentration of employment in low productivity and low wage jobs and underutilization of labour, the rate of modern sector labour absorption remains the major policy concern.
