Using International Institutions to Improve Public Procurement

The World Trade Organization's voluntary rules on governmentprocurement are a useful mechanism for ensuring that publicprocurement procedures are efficient. They also provide an opportunityto reduce the uncertainty of participants by increasing transparencyand accountability. Yet most developing countries have chosennot to subject their procurement policies to international disciiplinesand multilateral surveillance. Their reasons may include anunfamiliarity with the government procurement agreement (GPA);a perception that the potential payoffs are small; a desireto discriminate in favor of domestic firms; or the successfulopposition of groups that benefit from the current regimes.Although the economic rationales for abstaining from the GPAare not compelling, a quid pro quo for accession may be neededto overcome opposition by special interests. Developing countryprocurement markets are large enough that governments may beable to make accession to the GPA conditional on temporary exceptionsto multilateral disczplines or on better access to export markets.      

Credit Constraints in Manufacturing Enterprises in Africa

We investigate the question of whether firms in Africa's manufacturingsector are credit constrained. The fact that few firms obtaincredit is not sufficient to prove constraints, since certainfirms may not have a demand for credit while others may be refusedcredit as part of profit maximising behaviour by banks. To investigatethis question, we use direct evidence on whether firms had ademand of credit and whether their demand was satisfied in theformal credit market, based on panel data on firms in the manufacturingsector from six African countries. Of those firms with a demandfor credit, only a quarter obtained a formal sector loan. Ouranalysis suggests that while banks allocate credit on the basisof expected profits, micro or small firms are much less likelyto get a loan than large firms. We also find that outstandingdebt is positively related with obtaining further lending. Therole of outstanding debt is likely to be a reflection of inefficiencyin credit markets, while the fact that size matters is consistentwith a bias as well, although we cannot totally exclude thatthey reflect transactions costs on the part of banks. We presentan analysis showing how much more profitable small firms mustbe to obtain a loan than large firms.     

LA DÉLÉGATION DES SERVICES PUBLICS AUX ASSOCIATIONS PAR LES COLLECTIVITÉS LOCALES:

RÉSUMÉ ** : Dans le cadre communal français, des biens collectifs locaux sont offerts simultanement par les municipalités et par les associations. Toutefois, l'offre publique ne signifie pas toujours la production publique. Les municipalités peuvent ainsi déléguer la gestion de services collectifs locaux à des entreprises privées ou à des associations. La plupart du temps, les communes se contenteront de subventionner laproduction associative.
Aprés avoir précisé la distinction entre fourniture et production de biens, et le cadre légal et administratif particulier dans lequel s'inscrit la fourniture publique communale des biens et services collectifs locaux, nous soulignons les causes et les formes dupartenariat entre secteur public communal et associations, et les catégories d'actions associatives répondant aux attentes des municipalités.     

Setting people up for success: How the Portman Ritz‐Carlton hotel gets the best from its people

In China, where many multinational companies face a constant shortage of talent and high employee turnover, the Portman Ritz‐Carlton Hotel has been able to attract, develop, and retain high‐quality talent to deliver excellent customer service and ensure profitable growth. Under the leadership of Mark DeCocinis since 1998, the Portman Ritz‐Carlton has not only been named as the “Best Employer in Asia” by Hewitt Associates three consecutive times, but has also rated the highest in employee satisfaction among all of the Ritz‐Carlton's 59 hotels worldwide for five consecutive years. How can DeCocinis and his leadership team achieve such remarkable results? In his interview with Arthur Yeung, Mark DeCocinis, general manager of the Port‐man Ritz‐Carlton and regional vice president, Asia‐Pacific, of the Ritz‐Carlton Hotel Company, shares his philosophy and practices on talent management in China and elsewhere. © 2006 Wiley Periodicals, Inc.     

Expectations, the business cycle and the Mexican peso crisis

The 1994–95 ‘peso’ crisis did not displaycharacteristics which allow it to be easily captured by traditionalcrisis models. Models based on Minsky's financial fragilityhypothesis offer more persuasive accounts but have been supportedby relatively little direct empirical evidence. This paper providessuch evidence, with particular attention being paid to the roleof domestic financial liberalisation in the process. Minsky'shypotheses about the evolution of expectations over the businesscycle are tracked using business survey data. In addition, crisisindicators are constructed, reflecting the changing vulnerabilityof the economy to shocks. The findings support a Minskyian interpretationof the crisis.     

Two-stage flowshop earliness and tardiness machine scheduling involving a common due window

This paper studies a non-preemptive two-stage flowshop scheduling problem to minimize the earliness and tardiness under the environment of a common due window. The window size and the window location are considered to be given parameters. The just-in-time problem exists naturally and has many practical applications. The problem is shown to be NP-complete in the strong sense. We develop a branch and bound algorithm and a heuristic to solve the problem. We conduct the computational experiments to test the performances of the algorithms. A strong lower bound is derived for the branch and bound algorithm that can efficiently solve 15 jobs problem for about 5 minutes. The heuristic is shown to be efficient and effective, which can solve the problem of 150 jobs for about 20 seconds and provide near-optimal solution. We justify that the heuristic is an excellent solution approach for large problem instances. We also show that four special cases are either polynomial solvable or NP-complete in the ordinary sense.     

Protection and Trade in Services: A Survey

This paper surveys the literature on trade in services, focusing on the policies that are used to restrict such trade, the gains from liberalization, and the institutional mechanisms that have been adopted in the pursuit of liberalization. The paper argues that technological progress and international trade negotiations are likely to keep liberalization of trade in services a high profile policy issue. It also suggests that the research agenda should focus on developing better estimates of the welfare costs of protectionism in the service sector.
