Social norms,coordination and collaboration in heterogeneous teams

This paper considers the coordinating role of social norms in a heterogeneous team of workers. We define an optimal unit of production as a form of organisation involving several teams and members, with the following properties: (i) a social norm operating to coordinate individual efforts; (ii) a team with heterogeneous skills, enabling generation of synergies. Our model suggests that competences of the best worker are transferred to his or her peers. This collaborative process enhances team efficiency but only if there is an implicit ex ante coordinating device based on social norms that discourage free riding.

Informal barriers and agricultural trade: does monetary integration matter?

EU enlargement and the recent sovereign‐debt crisis of Euro zone countries have revived the debate around the (European Monetary Union) EMU. In this article we ask how informal barriers to agricultural and food trade have changed since the introduction of the common European currency, and whether this evolution can be attributed to monetary integration. We focus on the foreign trade of the 11 EMU founder countries over a nine‐year period covering the creation of the EMU and find a diminishing marginal trade impact of both information and institutional barriers. We find a lower level of trade barriers, but cannot attribute this outcome to the introduction to the Euro.     

Employee recognition,meaningfulness and behavioural involvement: test of a moderated mediation model

Abstract

This study examines how and under what conditions recognition practices are related to employee behavioural involvement at work. Combining social cognitive theory, social information processing theory and self-concordance theory, we develop and test a moderated mediation model in which (a) manager recognition promotes behavioural involvement both directly and indirectly through the intervening role of meaningfulness and (b) coworker recognition strengthens the benefits of manager recognition to meaningfulness and subsequent behavioural involvement. The results of a study of 130 employees provided empirical support for our model. These findings help clarify how different sources of recognition can shape the effective behavioural involvement in the workplace; they also emphasize the role of meaningfulness as an important psychological mechanism that explains the recognition–behaviour relation. The implications for theory and practice are discussed.     

Revisiting the core-periphery view of EMU

This study extends Bayoumi and Eichengreen's (1993) empirical methodology in order to give a reappraisal of the core-periphery view of the enlarged euro area. We show how to derive two useful indices from the “correlation box” formed by aggregate demand and supply shocks. One measures the Euclidean distance to the core, while the other reveals whether shock asymmetry comes mostly from the production or the demand side. Using data over 1996–2008 on 21 countries and iterative VAR estimates, we find evidence of a gradual move to the symmetric core while new EMU Member States still remain at the very periphery.     

Aid for Trade in Developing Countries: Complex Linkages for Real Effectiveness*

Abstract: Aid for trade is intended to support the integration of developing countries into the world trading system. Although this form of aid is being hailed as a promising new development tool, it lacks the strategic dimension that it needs if it is to be truly effective and fulfill donors' policy commitments. From a theoretical perspective, this paper presents the various aid‐for‐trade categories and analyzes the linkages between foreign direct investment, aid for trade and development. It also presents a typology of trade‐related needs for a panel of countries, to serve as a guide for donors in formulating their aid supply strategies. This typology reveals a number of disparities between countries and regions, as well as a low level of regional integration. Trade‐related needs are particularly significant in West Africa and East Africa, and substantial in the infrastructure sector. This paper also stresses the importance of refining the formulation of actual demand by beneficiaries, structuring the aid supply in accordance with donors' specific areas of expertise and enhancing coordination among the various stakeholders, both public and private. Lastly, further trade liberalization will not by itself suffice to generate strong growth and improve the geographical and sectoral distribution of foreign direct investment. Factors such as political stability, the business climate, physical infrastructure, institutions and human capital also play a fundamental role. Of particular importance is the coherence of trade, sectoral, macroeconomic and tax policies, not only within each country and region but also between industrialized and developing countries.     

Armington Elasticities and Tariff Regime: An Application to European Union Rice Imports

The European Union’s (EU) import sources for rice include developing countries and least developed countries (LDCs). The EU has made a commitment to allow duty‐free and quota‐free access to rice imports originating in the LDCs from September 2009 onward. The purpose of this article is to answer two questions: (1) does the inclusion of import tariffs lead to different estimated Armington elasticities? (2) when a discriminating tariff is introduced, what happens to the market share of large rice exporters to the EU, especially of poor countries? We present the Armington model, derived from a constant elasticity of substitution (CES) utility function, and a non‐homothetic CES utility functional form, which is more flexible. We then estimate the Armington model, with and without the inclusion of a tariff, and we compare the elasticities. Lastly, we model five scenarios with different discriminated import tariff rates to calculate the changes in the market access of large rice exporters to the EU. Our empirical results show the importance of non‐homothetic preferences and import tariffs. Ignoring import tariffs and the non‐homothetic parameter may produce results which are biased and of uncertain validity. Furthermore, the simulation findings demonstrate that, in spite of a large difference between import tariff rate of Suriname and other countries (scenario V), its market access would not change greatly. This may be caused by supply side problems like poor infrastructures, weak technology and small capacity production in LDCs.
