An evolutionary approach to the delimitation of labour market areas: an empirical application for Chile

An evolutionary approach to the delimitation of labour market areas: an empirical application for Chile. Spatial Economic Analysis. Labour market areas (LMAs) are argued to represent a more appropriate policy framework than administrative units for the analysis of spatial labour market activity. This article develops LMAs for Chile by applying an evolutionary computation approach. This innovative approach defines LMAs through an optimization process by maximization of internal cohesion, subject to restrictions of minimum levels of self-containment and population. To evaluate the appropriateness of the LMAs, comparative analyses are performed between alternative delimitations based on different parameter configurations of the proposed method versus administrative boundaries and the most widely used method for official LMA delimitation, the travel-to-work areas method.     

How to maximize golden opinions

In this article, we aim to model the level and structure of the dependence between the world's leading stock markets and those of the emerging market groups?–?Europe, Latin America and Far East. To this end we use a mixture model of Gaussian, Gumbel and Gumbel survival copulas. Our results indicate that none of the pairs of stock markets exhibit a right-tail dependence structure. All valid models exhibit a mixture of Gaussian and left-tail dependence structure. Our findings imply that Gaussian dependence structure is dominant in most of the models. The emerging equity markets in the European region exhibit the most significant dependence structure with the world leaders. Furthermore, most of the emerging equity markets have a significant dependence structure with the US stock market. We further compare our findings with the results of the conventional correlation coefficients and conclude the importance of using copula models in analysing the portfolio diversification opportunities. Our findings overall indicate two important remarks: First, the copula models reveal better indicators for global investors to establish a diversified portfolio; Second, international equity markets exhibit significant dependence, which leaves a smaller opportunity to benefit from international portfolio diversification.     

Women,men and organic food: differences in their attitudes and willingness to pay. A Spanish case study

The main purpose of this work consists of displaying the different attitudes of men and women towards organic food, and their willingness to pay for it, in three different consumer intensities: usual, occasional and potential consumers. Several surveys have been carried out to obtain a representative sample of regular food purchasers living in Castilla‐La Mancha (Spain). Statistic analysis previously detecting significant differences with regard to gender and type of consumer has been conducted by univariate analysis to describe attitudes, and multivariate analysis, through ‘logit’ models, to calculate maximum willingness to pay. Results show that women have a more favourable attitude (directly related to their lifestyle) to the purchase and consumption of organic food than men, whereas men are inclined to pay a higher price for organic food than women. In general, men are disposed to pay a higher increase in price than women.     

Mars or Mercury redux: The geopolitics of bilateral trade agreements

We analyse the role of economic and security considerations in bilateral trade agreements. We use the pre‐World War I period to test whether trade agreements are governed by standard gravity variables, or by instead—or in addition—geopolitical factors. While we like others find support for standard gravity variables, we also find that defence pacts boost the probability of trade agreements by as much as 20 percentage points. Our estimates imply that were the U.S. to alienate its geopolitical allies, the likelihood and benefits of successful bilateral agreements would fall significantly. Trade creation from an agreement between the U.S. and E.U. countries would decline by about 0.6 per cent of total U.S. exports.

意大利国债续发行制度对我国的启示

与国外发达的政府债券市场相比,我国在通过续发行制度提高国债流动性、提高关键期限国债的市场地位、促进国债定价效率方面,还存在明显的不足。本文以意大利国债市场为分析对象,对其相关的续发行制度设计、国债期限安排、理论依据进行分析,指出我国国债市场存在流通期次过多、单期国债流通量过低的问题,并从国库现金管理、交易机制和投资者结构等方面,尝试为未来我国国债续发行制度框架提供有价值的建议。     

Industrial marketing in Romania

This article by Dr. Lilian Cre?u facilitates an understanding of industrial marketing procedures in Romania. In the author's country industrial marketing has been, until recently, the least developed branch of marketing activity. However, as the Romanian economy develops (with a predicted 48% of industrial production in 1975 consisting of new or modernized products), classical central planning may become insufficient for accurately predicting and meeting Romania's need for industrial goods. Some autonomous decisionmaking by economic subunits may become necessary. It is possible, therefore, that industrial marketing activity at the microeconomic level will increase. Lilian Cre?u attempts to demonstrate this last point by indicating the changes in the concept and modus operandi of management which are taking place under the impetus of economic expansion.     

The optimal disposition decision for product returns

We provide an analytic model for the optimal disposition decision for product returns. The manager decides which product returns to accept for processing at the remanufacturing facility, and which ones to sell immediately as-is at a salvage value. High congestion levels in the remanufacturing facility delay the sale of the remanufactured product at the secondary market, decreasing the value at which it can be sold; this may imply a more attractive salvaging option. This is particularly important for high-tech products with short life cycles, such as computers and printers. We propose a two-step policy. In the first step, the returned product’s random processing time is observed. In the second step, a disposition decision is made: if the processing time is larger than a threshold k* the product is salvaged; otherwise the product is remanufactured. We provide an approximate procedure to compute k* in industrial settings. Our numerical study demonstrates the superiority of our policy over the current industrial practice ignoring the time value of money.     

A weighty issue revisited: the dynamic effect of body weight on earnings and satisfaction in Germany

We estimate the relationship between changes in the body mass index (bmi) and wages or satisfaction, respectively, in a panel of German employees. In contrast to previous findings, our dynamic models indicate an inverse u-shaped association between bmi and wages. As the implied maximum occurs in the ‘overweight’ category, the positive trend in weight may not yet constitute a major limitation to productivity. Further investigation points out a stronger association among young workers and workers with jobs that are less protected. Work satisfaction of young workers is associated with bmi beyond the effect of earnings.
