WHITHER GERMANY AND THE EMU IN A CHALLENGING ENVIRONMENT?*

While the German economy may currently be a bright spot in Europe, it has faced substantial challenges in recent years. Moreover, tensions are rising regarding Germany's responsibilities and opportunities as a member of the European Monetary Union. Other studies have documented the difficulties that Germany has encountered as a result of the unification and further integration of Europe. This paper adds to that literature by using an aggregate translog cost function approach to examine the relationships among inputs of domestic capital and labour and imports. Our findings indicate that the input pairs of capital‐labour and labour‐imports are substitutes. The substitutes relationship between labour and imports, which has become stronger over time, suggests that increasing globalisation will add to Germany's unemployment woes. Capital and imports appear to be weak complements, but that relationship is not statistically significant. The results also suggest that imports are playing an increasingly important role in Germany's aggregate production, accentuating the role of the international environment.     

Project Labor Agreements' Effect on School Construction Costs in Massachusetts

This paper investigates the impact of Project Labor Agreements (PLAs) on school construction cost in Massachusetts. Although simple models exhibit a large positive effect of PLAs on construction costs, such effects are absent from more completely specified models. Further investigation finds sufficient dissimilarity in schools built with and without PLAs that it is difficult to distinguish the cost effects of PLAs from the cost effects of factors that underlie the use of PLAs.     

MAQUILADORA RESPONSE TO U.S. AND ASIAN RELATIVE WAGE RATE CHANGES

ThiS paper investigates whether the output of the Mexican maquiladoras is an alternative to production in the Pacific Rim. The analysis involves estimating supply functions for Mexican maquiladora output using relative wage data for Mexico, Singapore, and the United States. It also involves estimating the impact of relative wage rates on maquiladora output in five industries as well as on more aggregated levels. Results indicate that production in Mexico and in the Pacific Rim are substitutes, although this relationship is stronger for some industries than for others.     

Changes in Union Wage Effects by Industry: A Fresh Look at the Evidence

Unions suffered a modest decline in their capacity to increase wages over nonunion levels between the late 1970s and the middle 1990s according to evidence presented here. The decline in relative wages was significant in only 13 (of 78) industries examined; in 11 industries the differential increased significantly. The industrially disaggregated econometric evidence is broadly consistent with institutional evidence about developments in particular industries; however, more industry-grounded research is clearly warranted.     

Public Wage Differentials and the Public Administration "Industry"

The public sector consists of two broad sub samples, administrators and no administrators. The two groups have very different occupational compositions and contrasting patterns of compensation. Inconsistent treatment of these sub samples has led to past government differentials, which are not comparable. While administrators remain overpaid relative to their private sector counterparts, no administrators are underpaid relative to their counterparts. Moreover, public wage differentials way substantially in sign and magnitude from industry to industry. Such results demonstrate that no simple, homogeneous government differential exists.     

A CRITICAL ANALYSIS OF CLIMATE CHANGE POLICY RESEARCH

After more than a decade of scientific warning, the policy community has begun to take up the challenge of global climate change. This paper considers recent efforts to analyze policymaking in this area. Shortcomings in present policy research include: (i) inconsistencies in data and methods, (ii) myopic vision of available options, (Hi) overly anthropocentric cost/benefit assessments, (iv) inadequate treatment of uncertainly and irreversibility, (v) lack of recognition of developing and developed countries' differential motives, (vi) unsatisfactory presentation and interpretation of results, and (vii) limited peer review.     

FIRM SIZE AND EFFICIENCY IN THE SOUTH AFRICAN MOTOR VEHICLE INDUSTRY*

The South African motor vehicle industry has historically been considered a critical industry in the South African economy and the target of numerous government policies designed to protect it and/or increase its international competitiveness. This study examines the cost performance of firms in this industry according to their size, using data categorised by output level. The results are consistent with statistically significant economies of scale at the lowest output levels and a cost inefficiency averaging from about seven to nine per cent for all firms. The findings also suggest that all else equal, the smallest firms and the largest firms have lower unit costs than mid‐sized firms. While this work suggests that policies that would give incentives for the smallest firms to increase their scale of operations might help to reduce their unit costs, further investigation needs to be done with respect to why firms in the mid‐level size categories appear to be less efficient.
