Production planning and inventories optimization: A backward approach in the convex storage cost case

We study the deterministic optimization problem of a profit-maximizing firm which plans its sales/production schedule. The firm controls both its production and sales rates and knows the revenue associated to a given level of sales, as well as its production and storage costs. The revenue and the production cost are assumed to be respectively concave and convex. In Chazal et al. [Chazal, M., Jouini, E., Tahraoui, R., 2003. Production planning and inventories optimization with a general storage cost function. Nonlinear Analysis 54, 1365–1395], we provide an existence result and derive some necessary conditions of optimality. Here, we further assume that the storage cost is convex. This allows us to relate the optimal planning problem to the study of a backward integro-differential equation, from which we obtain an explicit construction of the optimal plan.     

Technology gaps in European banking: Put the blame on inputs or outputs?

This paper investigates the production efficiency of 12 European banking systems over the period 1997–2004, taking into account possible technology heterogeneity. Using a non-parametric metafrontier framework, efficiency and metatechnology ratio measures are computed and decomposed into input- and output-invariant components. Empirical findings indicate the existence of significant and rather increasing technology heterogeneity within European banking. A typology of the national banking systems is also developed, based on the overall productive performance with respect to the European technological edge, the absorptive capacity and the role of knowledge spillover effects. Decomposition results draw attention to catching up policies focusing on input and/or output scale adjustments.

我国资本、劳动力与经济增长关系的分析——基于ARMA理论下的生产函数研究

柯布-道格拉斯生产函数用于反映经济领域中产出和各个要素投入之间的关系.本文在1978-2008年我国劳动力、资本存量和经济总产出的数据基础上,运用时间序列ARMA和回归相结合的计量模型,分析测量了柯布-道格拉斯生产函数中各个参数的数值,并对模型的拟合优良程度和其参数的数理意义进行了相关的统计检验.最后根据计量分析和经济意义分析所得出的结论为,劳动力的投入在我国的经济增长过程中起着主要的作用,当期劳动力增加1％,平均来说经济增长为0.47％.     

The effects of real exchange rate depreciation on stochastic producer prices in low-income agriculture

This paper considers the effects of real exchange rate depreciation on stochastic agricultural producer prices in low-income agriculture. Conventional wisdom, that real depreciation achieved through nominal currency devaluation stimulates tradables production, does not universally hold in the presence of stochastic prices. In fact, real depreciation is only stimulative in two cases–importables that remain importable and nontradables that become exportable. GARCH estimation of time-series price data on several commodities from Madagascar support the hypotheses generated by the analytical model.

Policies for the development of knowledge-intensive local production systems

Starting from the empirical literature concerning the analysisof industrial districts, this paper focuses on the importanceof industrial policies in supporting the development and consolidationof local production systems. Here, institutions and marketsare envisaged as equally important for long-term performance.The objective is to propose a conceptual framework for the formulationof public policies that places organisational learning at thecentre of interest.
