THE DISTRIBUTION OF HOUSEHOLD INCOME AND EXPENDITURE IN PORTUGAL: 1980 AND 1990

From 1980 to 1990 Portugal experienced a generalized liberalization of economic activity, due in large part to its 1986 integration in the European Union. This paper studies the changes in the Portuguese distribution of household income and expenditure during this period, using micro-data on household budgets and applying recent developments in statistical inference for Lorenz curves. We find a significant increase in six measures of welfare and an unambiguous decrease in the inequality of the respective distributions. Different explanations for the findings of decreased inequality are discussed.     

An analysis of the construct “involvement” in consumer behaviour

The aim of this paper is to analyse the construct involvement. Specifically, the present work extends the sphere of study of the construct involvement at brand level, applying it to Denominations of Origin (D.O.s). Hence, after an overview of the concept, it suggests a cognitive approach to the measurement of involvement. It proposes as indicators the number of values associated with this designation, the centrality of these values and the intensity of the association. In this delimitation of the concept, a model is presented that is set within the framework of an analysis of the decision-making process adopted by consumers when purchasing wine. This postulates that temporary involvement with a D.O. has explanatory power, as does the direct effect of the regular outcomes of a permanent involvement with such a designation on the process in question. In addition, a correlation is proposed between the state of temporary involvement with a D.O. and the continuing consequences of a permanent involvement with this designation.     

On the unique features of post-disaster humanitarian logistics

Logistic activity can be thought of as a socio-technical process whereby a social network of individuals orchestrates a series of technical activities using supporting systems such as transportation and communications. To understand the functioning of the entire system requires proper consideration of all its components. We identify seven key components: the objectives being pursued, the origin of the commodity flows to be transported, knowledge of demand, the decision-making structure, periodicity and volume of logistic activities, and the state of the social networks and supporting systems. Based on our analysis of the differences between commercial and humanitarian logistics, we pinpoint research gaps that need to be filled to enhance both the efficiency of humanitarian logistics and the realism of the mathematical models designed to support it.We argue that humanitarian logistics is too broad a field to fit neatly into a single definition of operational conditions. At one end of the spectrum we find humanitarian logistic efforts of the kind conducted in long-term disaster recovery and humanitarian assistance, where operational efficiency – akin to commercial logistics – is a prime consideration. At the other, post-disaster humanitarian logistic operations involved in disaster response and short-term recovery activities represent a vastly different operational environment, often in chaotic settings where urgent needs, life-or-death decisions and scarce resources are the norm. The huge contrast between these operational environments requires that they be treated separately.     

The impact of public investment on private investment spending in Latin America: 1980–95

This paper investigates the theoretical and empirical links between key economic variables and private spending in Latin America during 1980 to 1995. The empirical findings of this paper directly address the complementarity hypothesis which suggests that increases in public investment spending raise the marginal productivity of private capital, thereby inducing higher rates of private investment spending. This paper also addresses the issue of whether changes in the real exchange rate (expenditure-switching policies) have a deflationary effect on the economics of Latin America. The findings in this paper make an important contribution to the ongoing debate about which policies need to be promoted to raise and sustain the rate of private capital formation in Latin America—the region's future source of employment and income creation.     

中国因素对近年来日本产业空洞化的影响分析

近年来，有关产业空洞化问题的讨论在日本再次形成高潮，并与“中国因素”联系在一起。而分析日本对外直接投资的增长与日本进出口和就业的关系得知，“中国因素”不仅不是日本产业空洞化的祸首，反而是新一轮景气回升的重要动力．中国因素加快了日本逆工业化进程，尽管使日本制造业失业人数增加，但导致日本产业空洞化的真正原因是服务业过多的规制和劳动力市场缺乏弹性，使逆工业化过程中制造业释放出的失业人员不能向服务业进行有效转移。     

A Model of Elitist Qualification

This paper deals with the collective qualification of members of society as belonging to a certain category or group based on a fixed attribute. Our model contains three main features: the existence of individual gradual opinions, the notion of elitism (only the opinions of certain individuals are taken into account to delineate the reference group), and the idea of sequentiality (elites are successively created by using the previous elites’ opinions on a social decision scheme). The main results of the paper characterize when this sequential procedure converges for some intuitive ways of aggregating individual opinions. Finally, we analyze the role of convergence for two extra basic properties (symmetry and contractiveness) that elitist rules should possess.     

POLICY PAPER: The Technical Process of Bank Privatization in Mexico

This paper describes the process of Mexican bank privatization that took place in 1991. We show that the Mexican government was very careful to ensure due process and transparency through the entire bank privatization process. However, the lack of a legal and regulatory framework and lax oversight shadowed the success of the technical process. Hence, the financial system in Mexico had to deal with a banking crisis shortly after their privatization, in 1994.     

Central bank haircut policy

We present a model of central bank collateralized lending to study the optimal choice of the haircut policy. We show that a lending facility provides a bundle of two types of insurance: insurance against liquidity risk as well as insurance against downside risk of the collateral. Setting a haircut therefore involves balancing the trade-off between relaxing the liquidity constraints of agents on one hand, and increasing potential inflation risk and distorting the portfolio choices of agents on the other. We argue that the optimal haircut is higher when the central bank is unable to lend exclusively to agents who actually need liquidity. Finally, for a temporary surprise drop in the haircut, the central bank can be more aggressive than when setting a permanent level of the haircut.
