工程中的伦理问题及工程师的责任

工程中的伦理问题在工程活动的过程中表现为设计的伦理问题、实施的伦理问题和导致人工物（如工厂、民用工程建筑物及基础设施）和环境之间的关系问题。设计是工程的起始阶段并且是工程过程特性的重要体现。工程设计既限制又使得人类的活动被介入到世界和自然过程创造人工物的实施阶段。工程的结果拓展了人类的能力并调节了人类行动的许多方面。因此,工程被解释为引发在物理世界和人们活动世界中的具有因果关联和象征性属性的人工现实。工程人工物或者基础设施形塑社会和自然环境,它们因此也能够被评估。工程师的责任有设计责任、关照工程成果的责任及维护社会和自然环境的责任三种类型。     

Open access,common property and scarcity rent in fisheries

Open access resources are frequently not managed efficiently, resulting in falling stock levels and a declining income for fishermen. In the late 1970's, the policy response to this problem was the implementation of 200-mile fishing zones, which enabled the European Union to formulate and implement the Common Fisheries Policy, aimed at (among other things) conservation and distribution of available stocks. In Germany, this shift from an open access regime towards a common property regime had favourable outcomes. The trend of falling prices was reversed. The conclusion was that intertemporal efficiency had increased as a result of (inter)governmental policy. Apparently, a wedge was formed between price and marginal harvesting costs, implying that scarcity rent had returned as a component of prices.     

Regional and sectoral dynamics of the Dutch staffing labor cycle

This study analyzes the dynamic characteristics of staffing employment across different business sectors and across different geographical regions in The Netherlands. We analyze a micro data set of the market leader of the Dutch staffing employment market, i.e. Randstad. We apply the dynamic factor model to extract common information out of a large data set and to isolate business cycle frequencies with the aim of forecasting staffing and total employment. We identify regions and sectors whose cyclical developments lead the staffing labor cycle at the country level. The dynamic factor model exploits these leading characteristics at the disaggregate level to forecast the country aggregate. Finally, both dynamic and static factors turn out to be predictive summary statistics of the micro data set when employed to forecast total employment at the country level.     

Environment versus growth — A criticism of “degrowth” and a plea for “a-growth”

In recent debates on environmental problems and policies, the strategy of “degrowth” has appeared as an alternative to the paradigm of economic growth. This new notion is critically evaluated by considering five common interpretations of it. One conclusion is that these multiple interpretations make it an ambiguous and rather confusing concept. Another is that degrowth may not be an effective, let alone an efficient strategy to reduce environmental pressure. It is subsequently argued that “a-growth,” i.e. being indifferent about growth, is a more logical social aim to substitute for the current goal of economic growth, given that GDP (per capita) is a very imperfect indicator of social welfare. In addition, focusing ex ante on public policy is considered to be a strategy which ultimately is more likely to obtain the necessary democratic-political support than an ex ante, explicit degrowth strategy. In line with this, a policy package is proposed which consists of six elements, some of which relate to concerns raised by degrowth supporters.     

Fear of Floating and Pegging: A Simultaneous Choice Model of De Jure and De Facto Exchange Rate Regimes in Developing Countries

We present an analysis of the determinants of de jure and de facto exchange rate regimes based on a panel probit model with simultaneous equations. The model is estimated using simulation-based maximum likelihood methods. The empirical results suggest a triangular structure of the model such that the choice of de facto regimes depends on the choice of de jure regimes but not vice versa. This gives rise to a novel interpretation of regime discrepancies.

Does GDP Distort Mexico's Economic Performance?

Between 1961 and 1980, Mexico's gross domestic product (GDP) per capita grew nearly 3.50% annually. During the 1980s, however, it shrank about 0.50% per year. GDP figures suggest that there was sustained economic growth for the 1960s and 1970s, changing suddenly to contraction in the 1980s. This impression may be misleading. GDP does not account for housework or informal production outside households. Further, GDP also may be distorted by transactional activities, which are expenditures to support transactions, not actual output consumed. This study recalculates output for Mexico for the 1961-1990 sample period, controlling for transactional activities and nonmarket production. We find that GDP misstates Mexico's “actual” economic growth. In the 1960s, the economy expanded more quickly than GDP suggests. But in the 1970s, growth was less than half that of the 1960s. The economy indeed slumped in the 1980s, but not as terribly as the official figures indicate. Mexico's economy did not collapse suddenly in the early 1980s; actual economic growth had slowed dramatically during the 1970s.
