Do we really care about Biodiversity?

This paper addresses from an economic perspective the issue of global biodiversity conservation. It challenges the perception that the world really cares a great deal about biodiversity and is prepared to pay the full cost of maintaining this stock of natural capital. Despite the existence of a plethora of international agreements there still seems to be a global ‘deficit of care’ surrounding efforts to combat challenges such as those posed by global warming and biodiversity conservation. More light can be thrown on the degree of care by measuring both the actual expenditures and the stated willingness to pay for biodiversity conservation. However, actual expenditures are much lower than willingness to pay estimates recorded in the published literature. Using the criteria that the ‘right’ amount of conservation effort is one where the marginal economic benefits from conservation just equal the marginal costs of conservation, the paper explores the biodiversity conservation conundrum and concluded that, on the available evidence, the world does not care too much about this natural capital stock and bequests to future generations.

Is Meta-Analysis a Noah's Ark for Non-Market Valuation?

This paper describes meta-analytical methods as they have been appliedto non-market valuation research. These studies have been used to reviewand synthesize literature and, more recently, in benefit transfer. Thissecond use imposes a higher standard on the consistency in economicconcepts being summarized and in the resources included in ameta-analysis. To meet this need, the paper proposes and illustrates astructural framework using a generalized method of moments estimator toestimate the parameters of a preference function with the benefitsestimates usually encountered in meta-analytic summaries.

Trade and Renewable Resources in a Second Best World: An Overview

We provide an overview and introduction to the emerging field of trade and renewable resources, and discuss the potential impact of trade liberalization on welfare and resource conservation. A key factor determining the effect of trade reform is the institutional context or property rights regime, and our survey is organized such that it loosely follows the development of new insights with respect to institutions in this literature. This implies a transition from the benevolent planners model to the polar opposite benchmark of open access in the 1990s. Currently the pendulum is swinging back towards management and regulation, but institutions are treated as endogenous. We discuss and compare various key models in some detail and search for common ground between protagonists and antagonists of free trade. Paper based on Keynote address by Erwin Bulte, 12th Annual Conference of the European Association of Environmental and Resource Economists, Bilbao (Spain), June 28–30, 2003.

我国收入贸易条件变动分析:1995～2004

收入贸易条件衡量的是一国在国际分工中获得的总体贸易利益的多少,在对我国贸易条件的变化进行分析时应当合理考虑收入贸易条件指数的变动。近年来我国的收入贸易条件指数呈现出持续改善的趋势,这表明外贸规模的扩大对国民经济发展做出了积极的贡献,仅仅根据商品贸易条件指数下降而得出我国贸易条件出现严重恶化的结论缺乏充分的根据。从国际经济竞争的现实背景来考虑,我国应当在保持收入贸易条件指数不恶化的情况下,继续大力推动出口贸易量较快地增长。     

我国绿色食品出口贸易中存在的问题及对策探析

20世纪90年代以来,绿色食品贸易在全球兴起并已成为人类社会可持续发展的必然选择。然而,尽管在国内绿色食品生产日益社会化、市场化、国际化的背景下,我国绿色食品已经呈现出蓬勃发展的良好态势,但出口数量和出口规模还是偏低。本文在分析我国绿色食品出口中存在的问题及原因的基础上,探索相应的对策,以期为我国绿色食品竞争优势的提升提供有益的思路。     

我国外贸技术溢出效应的国别差异分析

技术溢出是发展中国家追赶发达国家的重要路径,溢出的渠道包括国际贸易、FDI、R＆D合作、国外R＆D投资等。我们运用经拓展后的Coe＆Helpman的贸易溢出计量模型,试图将我国从商品贸易以及FDI中所获得的技术溢出纳入同一模型中加以综合分析,并对贸易带来的技术溢出效应进行国别差异分析,以判断不同类型国家对我国吸收技术溢出效应的影响。并在此基础上,提出了相应的政策建议。     

Output decline and the demise of the CMEA and the USSR: The case of Hungary

The direct effect of market losses in CMEA on Hungarian output was 4%, out of the 18% decline registered in gross output in 1988–1992. Total (direct and indirect) effects amounted to 8%. In the same period Hungary's export expansion in western markets led to direct and total effects equivalent to 2.9% and 5.6% of the 1988 output, respectively. The share of reorientation within this switch from east to west was not negligible, it amounted to 19% of respective trade volumes. The 1991 price explosion of imported inputs inhibited the activity of Hungarian firms only moderately, due to earlier realistic domestic prices. In 1991 Hungary suffered a 26% terms of trade loss, and could have experienced an income terms of trade loss of USD 1400 to 1600 million, had the trade volume of 1990 been repeated. Since adjustments in 1991, much smaller income losses accrued. Due to earlier special tax arrangements, much of the burden of terms of trade losses had to be born by the budget.
