Fiscal and monetary interactions when wage-setters are large: is there a role for corporatist policies?

This paper studies the macroeconomic consequences of alternative policy regimes in a closed economy where a central bank, a fiscal authority and a monopoly union interact via their effects on output and inflation. The analysis compares macroeconomic outcomes in a non-cooperative setting, where players may move sequentially or simultaneously, and in a regime of cooperation between the government and wage-setters. The cooperative regime captures a climate of accord among social parties that is finalised at common macroeconomic targets in the tradition of corporatism, as in the recent experience of “social pacts” in many European countries. The paper makes two main contributions. First, it shows that macroeconomic outcomes are suboptimal in the non-cooperative regime and may deliver extreme (undesirable) results even when all players share common ideal targets for output and inflation. All players would be better off with a less extreme value for output or inflation, yet they fail to reach a more advantageous allocation as long as there is an inherent conflict among their further objectives. Moreover, the result is robust to a change in the degree of central bank’s conservatism. Second, I find that cooperation between the government and the monopoly union towards common ideal targets for inflation, output and taxes enhances social welfare even in the absence of explicit coordination with the central bank.     

Interethnic relations,informal trading networks,and social integration: imitation,habits, and social evolution

The ethnically homogeneous middleman groups (EHMGs), which are informal trading networks, are ubiquitous in less-developed economies where the legal infrastructure for contract enforcement is not well developed. This paper develops a formal model of social interaction among members of the EHMG as well as in more general situations in a multi-ethnic or multi-cultural society consisting of identifiable ethnic or linguistic groups. Behavioral patterns are transmitted between generations and altered via imitation in social contacts. The model demonstrates how different discriminatory behavioral patterns can evolve and persist over time. One result is that the trust between such groups can increase due to a higher frequency of inter-group contacts. In concluding the paper, we speculate about how the model can be expanded to include changes in legal structures, especially contract law. This could lead to an increase in the trust between the different groups.     

The productive effect of transport infrastructures: does road transport liberalization matter?

In this paper we analyze the impact of motorway networks on production for a panel of twenty one manufacturing and service sectors of eleven EU countries observed over the period 1980–2003. In particular, we analyze if the degree of regulation of the road transport sector affects the link between productivity and motorway infrastructures. Overall results suggest that output elasticity with respect to motorway is found to be lower for countries characterised by a high degree of entry barriers in the road transport sector. This result is found to be more evident for industries which rely more heavily on transport services.     

Bilateral and regional trade elasticities of the EU

The traditional way of assessing the impact of currency depreciation and income on the trade balance has been to estimate the elasticity of trade volume to relative prices and income. The previous studies examine the problems associated with using aggregate data. The recent studies rely on bilateral data, yet another problem is that data for export and import prices are not available. Thus, this study proposes an alternative way of assessing the impact of currency depreciation by using the real exchange rate and the impact of income on bilateral trade. The models are applied between the EU and its major trading partners. Furthermore, the analysis includes the six major trading regions along side the eight major trading countries for 1980–2007, on the quarterly basis. This article uses the autoregressive distributive lag (ARDL) approach advocated by Pesaran and Pesaran (1997). Our results indicate a higher importance of income compared to the real exchange rate in defined bilateral export and import demand functions. In addition, the applied CUSUM and CUSUMSQ stability tests confirm the stability of estimated coefficients in most cases.     

Theoretical perspectives on strategic environmental management

Strategic Environmental Management (SEM) incorporates into firms' core strategies the transformation of products and processes that they believe an environmentally concerned society will increasingly demand. Significant threads have to do with the discovery of cost savings and market opportunities from reducing environmental impacts. SEM, like the environmental regulation hypothesis associated with Michael Porter, implies that society's efforts to reduce external environmental costs often lead to identification of hitherto-ignored or undeveloped profit possibilities. This would be surprising from the standpoint of neoclassical economic theory, to the extent that SEM utilizes available information about the potential costs and benefits of projects. Within the framework of evolutionary, capabilities-based theories of the firm, however, this discovery and its exploitation in SEM make perfect sense. Capabilities theory would imply that firms' intrinsic path dependence may previously have obscured such opportunities. This paper examines the theory of SEM, its implications for neoclassical and capabilities theories of the firm, and survey results drawn from the author's work with member companies in a regional pollution prevention roundtable.
