AS‐AD REVISITED: OVERSHOOTING ADJUSTMENT DYNAMICS UNDER NAÏVE EXPECTATIONS

We analyse the adjustment dynamics from a short‐term to a medium‐term equilibrium in a standard AS‐AD model à la Blanchard (2006, Macroeconomics, 4th edn, Prentice‐Hall, Upper Saddle River, NJ) for an open economy with fixed and flexible exchange rates. An explicit analysis suggests the local stability of the medium‐term equilibrium. However, an overshooting adjustment dynamics is possible for the exchange rate, a result that directly relates to the famous Dornbusch (1976, Journal of Political Economy, 84, pp. 1161–1176) analysis. In contrast to the latter, in the Blanchard framework it is obtained without assuming rational expectations and without relying upon saddle‐path stability.     

Trade policy and productivity

Previous studies on the determinants of productivity emphasized the role of trade and institutions but omitted trade policy due to endogeneity concerns. This paper considers the role of one important element of trade policy: free trade agreements (FTAs). Based on recent work on the determinants of FTAs, we suggest an instrument which is based on the propensity to enter an FTA due to (exogenous) geographical characteristics. We find that differences in institutional quality and trade, due to variations in geography and trade policy, have a sizeable effect on productivity and can explain the huge variation in per capita income across countries.     

The WTO Compatibility of the Economic Partnership Agreements between the EU and the ACP Countries

The economic partnership agreements (EPAs) to be negotiated between the European Union and six different ACP regions under the Cotonou Agreement are intended to be in conformity with WTO rules, i.e. satisfy GATT Article XXIV and GATS Article V. To what extent is this realistic? What would be the effects on the ACP countries?

The North American trade region

The North American Free Trade Agreement (NAFTA) that is to take effect at the beginning of 1994 will create a free trade area between three economies which differ substantially in terms of size and stage of development. What were the reasons that led the unequal partners, the USA, Canada and Mexico, to enter into closer trade integration? What will be the economic consequences for the countries involved and for world trade?     

Enhancing performance in small professional firms through vision communication and sharing

Despite evidence of a positive relationship, vision’s effects on performance are not fully understood, particularly in small professional service settings. This study advances prior research using a multi-stakeholder, multi-measure approach. It reports a positive relationship between vision-communication and -sharing on performance in Australian retail pharmacies using five measures—financial assessments, employee and customer satisfaction, productivity, and staff retention. Organizations whose managers communicate the vision to staff and whose employees share this vision outperform their peers across all business indicators and retain their employees longer. Financial performance and productivity were higher with long-term staff and managers.
