Towards A New Approach to Development Management1

Abstract: Since attaining political independence African countries have achieved significant improvements in a number of social welfare indicators. However, the record of socio-economic development in Africa is generally poor both in absolute terms and in comparison with other regions of the world. Various reasons have been given for Africa's poor development record. This paper suggests that approaches to development management so far adopted in Africa are inadequete, and it propose the conceptual elements for a new approach to development management. Résumé: Depuis leur accès à I'indépendance, un certain nombre d'indicateurs de bien-être social des pays africains se sont très nettement améliorés. Toutefois, les résultats concernant le développement socio-économique de l'Afrique est, en règle générale, médiocre en chiffres absolus et si on le compare avec d'autres régions du monde. Pour expliquer ces résultats, divers raisons ont été avancées. Ce document donne à penser que les approches adoptées jusqu'ici en Afrique, touchant la gestion du développement, sont inadaptées à la situation. L'auteur propose donc des éléments conceptuels pour une nouvelle approche de la gestion du développement     

流通股股东在股权分置改革中是否获得了财富增值？

本文的主要的日是从事后的角度分析流通股股东的股票财富在股权分置改革前后的变化.股权分置改革方案的提出和表决是流通股股东和非流通股股东之间的一个讨价还价过程,利益分配取决于双方的谈判力量.统计结果显示,从总体上看,流通股股东的财富在股改前后获得了7%的增值.非流通股比例、股改批次、控股股东性质、市净率是影响流通股股东获得财富增值的主要因素.虽然非流通股比例越大,非流通股股东支付的对价股票也越多,但是,流通股股东享受的财富增值却越低.非流通股比例与对价水平之间正的相关性掩盖了非流通股股东少付对价的事实.总的来说,对价方案是在维持流通股股东股改前后的财富不受损的基础上制定的,而不是补偿流通股股东历史上对上市公司的投入.     

中小企业应对反倾销集群化战略的博弈分析

本文建立了博弈模型,对我国遭受了国外反倾销比重很大的中小企业如何应对反倾销提出了集群化发展战略,从理论上分析中小企业在选择单独进入和集群进入时不同的博弈结果,得出中小企业选择集群进入时,无论东道国企业选择起诉,或者不起诉均会选择留在市场,而且一旦东道国企业起诉对其造成的损失,会比容忍对方进入的损失大,这便对东道国企业构成了一个可置信的威胁,使得东道国企业只能选择容忍中小企业进入其市场的策略,达到在不完全信息下的子博弈精炼纳什均衡,这一结论对我国中小企业应对反倾销的集群化发展战略提供了理论依据。     

Is Uniform Money Always Better than Separate Monies?

Previous studies that compare a uniform money with separate monies used models in which money is the only asset and in which individuals hold either zero or one unit of money. Here, the comparison is made using a model in which money coexists with a higher-return asset and in which individuals are permitted to hold richer portfolios of assets. The results show that a general conclusion is not possible. A uniform money has a higher expected utility than do separate monies in many examples. However, when the discount on bonds and uncertainty about the nationality of the trading partner are sufficiently high, then there are examples in which separate monies are better.

Exchange Rate Regime and Demand for Reserves: Evidence from Kenya,Mexico and Philippines

This paper empirically investigates the demand for international reserves (and foreign exchange reserves) during fixed and floating exchange rates periods in three developing countries: Kenya, Mexico and Philippines. Based on theoretical models, three factors are identified as important for the demand of international reserves and foreign reserves: average propensity to import, volume of imports and variability of reserves. The paper employs the cointegration methodology and error correction method to investigate the relationships. Cointegration tests results indicate a reliable long-run stationary relationship between the international reserves (and foreign exchange reserves) and the stated explanatory variables across countries and sub-periods of fixed and clean float. The error correction results indicate causality from the explanatory variables to the reserves during both the short and long run. This is true during both the fixed and the floating periods.

Migration and its Determinants: A Study of Two Communities in Colombia

Using data gathered by the author in two communities in Southwestern Colombia, this paper tests a model of migration which incorporates relative deprivation as one of many possible reasons to migrate. The study finds that the product of relative deprivation and family income not only has a sensible interpretation; it is a better predictor of migration than its two component variables alone. Results also show that families with the highest propensities to migrate are those with the most to gain in terms of being better able to reduce relative deprivation through successful migration. These families, however, are neither at the bottom nor at the top of the income distribution in their communities. The study also finds that those most likely to migrate to the USA conform most closely to the immigration policies of the USA.

Trade Costs,Trade Balances and Current Accounts: An Application of Gravity to Multilateral Trade

In this paper we test the well-known hypothesis of Obstfeld and Rogoff (NBER Macroeconomics Annual 7777:339–390, 2000) that trade costs are the key to explaining the so-called Feldstein–Horioka puzzle. Our approach has a number of novel features. First, we focus on the interrelationship between trade costs, the trade account and the Feldstein–Horioka puzzle. Second, we use the gravity model to estimate the effect of trade costs on bilateral trade and, third, we show how bilateral trade can be used to draw inferences about desired trade balances and desired intertemporal trade. Our econometric results provide strong support for the Obstfeld and Rogoff hypothesis and we are also able to reconcile our results with the so-called home bias puzzle.

Output Expectations and Forecasting of UK Manufacturing

This paper analyses both quarterly data from the Confederation of British Industry (CBI) Survey on respondents’ expectations of recent and forthcoming manufacturing output and monthly Office of National Statistics (ONS) figures on actual manufacturing output within the UK. Quarterly output expectations of the CBI manufacturers are explained from the monthly ONS observations using a bounded rationality approach. The logistic formulation models the diffusion process across respondents. There is a backward-looking CBI Survey perspective, explained by past ONS observations, and a forward-looking perspective, explained from future ONS statistics. Also, the forecasting of monthly manufacturing output from earlier values, along with the quarterly CBI Survey information, is examined and tested against the alternative Pesaran/Thomas method. The study provides econometric evidence for the validity of the logistic model and shows that bounded rationality can explain the formation of predictions among business managers in the UK manufacturing sector. The emerging consensus from the literature, supported by this paper, is that the logistic format is a superior approximation to the true data generating process compared with the earlier standard Anderson/Pesaran/Thomas approach. An adjustment to the Survey is used, which achieves perfect symmetry with up and down versions of the data. The benefits of this adjustment are tested in the forecasting section.

Relative Responsiveness of Bargaining Solutions to Changes in Status-quo Payoffs

It is a well-known fact that several prominent bargaining solutions are responsive to changes in status-quo (i.e., disagreement or fallback) payoffs. When an agent’s status-quo payoff increases, his solution payoff either stays the same or increases. A fully general result for these solutions’ status-quo point ranking is impossible to establish. In this paper, using an important class of bargaining problems, a ranking of the relative status-quo point responsiveness of prominent bargaining solutions is obtained. Using the Constant Elasticity of Substitution class of bargaining problems, regardless of the concavity of the Pareto frontier and the level of increase in one’s status-quo payoff, we find the equal gains solution is the most responsive with respect to changes in status-quo payoffs, followed by the Nash solution. The equal sacrifice solutions is the least responsive, followed by the Kalai/Smorodinsky solution.
