In this work we discuss some ideas and opinions related with teaching Metaheuristics in Business Schools. The main purpose of the work is to initiate a discussion and collaboration about this topic,with the final objective to improve the teaching and publicity of the area. The main topics to be discussed are the environment and focus of this teaching. We also present a SWOT analysis which lead us to the conclusion that the area of Metaheuristics only can win with the presentation and discussion of metaheuristics and related topics in Business Schools, since it consists in a excellent Decision Support tools for future potential users.

Perfil dos Turistas que Visitam a Ilha de São Vicente

O presente trabalho tem por objectivo definir o perfil do turista que visitou a ilha de São Vicente e avaliar o grau de satisfação do turista enquanto consumidor de diferentes bens e serviços, nos meses de Maio e Junho do decorrente ano. Para se fazer uma abordagem qualitativa falou-se da problemática do mercado turístico - procura e oferta turística – e a importância da segmentação desse sistema turístico juntamente com algumas teorias do comportamento do consumidor. Por sua vez, para o estudo do perfil e satisfação dos turistas utilizou-se uma abordagem quantitativa, através da aplicação de questionários no Aeroporto Internacional Cesária Évora e entrevistas aos estabelecimentos hoteleiros, 150 e 7 respectivamente. Após a análise explicativa, com base na bibliografia seleccionada, nas entrevistas e questionários realizados, os resultados da pesquisa indicam que estudar o perfil e a satisfação dos turistas permite fazer um levantamento de diversas variáveis importantes como, por exemplo, a nacionalidade do turista, a principal razão e objectivo da viagem e o que gostaram, ou desejavam ver no destino. E assim, entender-se o perfil do visitante e propor-se estratégias, que contribuam para um planeamento sustentável do desenvolvimento turístico na região pretendida. A complexidade do processo de decisão do turista por um ou outro destino é que verdadeiramente motiva esta pesquisa. The objective of the following work is to define the profile of a tourist that visited São Vicente, and evaluate the levels of satisfaction of the tourist as a consumer of different items and services, on May and June of the current year. For a quality methodological approach, the problematic of the touristic industry (demand and touristic offer) – the essential of subdivision of these touristic systems alongside with the principles of the consumer behavior were discussed. In continuity, to define the profile and satisfaction of the tourists, a quantity approach was also used, through the application of questionnaires at the International Airport Cesária Évora and interviews throughout hotel establishments, 150 and 7 respectively. After an explanatory analyses, based on a selected bibliography, the applied interviews and questionnaires, the outcome of this research shows that by studying the profile and the satisfaction of the tourists allows to have variable important results, for example, the tourist´s nationality, the main reason and objective of the trip and what they enjoyed or would like to see on their destination. Thus, understanding the visitor´s profile and suggesting strategies, that contributes for a sustainable planning of a touristic development on the intended region. The process complexity of the decision making of the tourist for one destination is truly the main motivation for this research.

Business cycle measurement with some theory

A method to evaluate cyclical models not requiring knowledge of the DGP and the exact specificationof the aggregate decision rules is proposed. We derive robust restrictions in a class of models; use someto identify structural shocks in the data and others to evaluate the class or contrast sub-models. Theapproach has good properties, even in small samples, and when the class of models is misspecified. Themethod is used to sort out the relevance of a certain friction (the presence of rule-of-thumb consumers)in a standard class of models.

Relative price riddles in international business cycle theory: Are transport costs the explanation?

We study relative price behavior in an international business cyclemodel with specialization in production, in which a goods marketfriction is introduced through transport costs. The transporttechnology allows for flexible transport costs. We analyze whetherthis extension can account for the striking differences betweentheory and data as far as the moments of terms of trade and realexchange rates are concerned. We find that transport costs increaseboth the volatility of the terms of trade and the volatility of thereal exchange rate. However, unless the transport technology isspecified by a Leontief technology, transport costs do not resolvethe quantitative discrepancies between theory and data. Asurprising result is that transport costs may actually lower thepersistence of the real exchange rate, a finding that is in contrastto much of the emphasis of the empirical literature.

Demonstração dos fluxos de caixa como instrumento de planeamento financeiro e de tomada de decisão

O presente trabalho tem como objectivo evidenciar a importancia da demonstração dos fluxos de caixa como instrumento de planeamento financeiro e de tomada de decisão. As informações fornecida pela demonstração dos fluxos de caixa serão de grande utilidade para a Administração, pois permitem compreender a alocação dos meios financeiros da entidade o que ajudará no planeamento financeiro e na tomada de decisões económico-financeiras. A demonstração dos fluxos de caixa como peça contabilística permite a Administração verificar a consistência dos planos projectados e estimar as exigências financeiras da entidade. O trabalho inclui uma abordagem teórica seguido de um estudo de caso. Na abordagem teórica, fez-se a apresentação das principais teorias e conceitos sobre o tema. O estudo de caso incidiu sobre uma empresa nacional, a Enacol, em que analisou-se a demonstração do fluxo de caixa dos ultimos três anos, bem como os indicadores económicos e financeiros possibilitando a análise da situação financeira da empresa. Foi também utilizada a entrevista a pessoas ligadas a área de contabilidade numa empresa. Os resultados obtidos mostram que a demonstração dos fluxos de caixa é um importante instrumento no planeamento financeiro e na tomada de decisões para a continuidade dos negócios das empresas. This paper aims to highlight the importance of the statement of cash flows as a tool for financial planning and decision making. All the information provided by the statement of cash flows will be very useful for the Administration, because they allow them to understand the allocation of the financial resources of the entity which will be a support in financial planning and decisionmaking in economic and financial areas. Being part of accounting, the statement of cash flows allows the Administration to verify the consistency of the projected plans and estimate the organization financial requirements. The following work includes a theoretical approach followed by a case study. Within the theoretical approach was made a presentation of the main theories and concepts on the subject while the case study focused on a national company, Enacol, in which we analyzed the statement of cash flows for the last three years, as well as the economic and financial indicators enabling the analysis of the financial situation of the company. It was also used an interview used for people connected to a company in the accounting field. Therefore, the results show that the statement of cash flows is an important tool in financial planning and decision making for the continuity of companies businesses.

Strategies for an integrated distribution problem

The problems arising in the logistics of commercial distribution are complexand involve several players and decision levels. One important decision isrelated with the design of the routes to distribute the products, in anefficient and inexpensive way.This article explores three different distribution strategies: the firststrategy corresponds to the classical vehicle routing problem; the second isa master route strategy with daily adaptations and the third is a strategythat takes into account the cross-functional planning through amulti-objective model with two objectives. All strategies are analyzed ina multi-period scenario. A metaheuristic based on the Iteratetd Local Search,is used to solve the models related with each strategy. A computationalexperiment is performed to evaluate the three strategies with respect to thetwo objectives. The cross functional planning strategy leads to solutions thatput in practice the coordination between functional areas and better meetbusiness objectives.

Is lumpy investment really irrelevant for the business cycle?

New-Keynesian (NK) models can only account for the dynamic effects of monetary policy shocks if it is assumed that aggregate capital accumulation is much smoother than it would be the case under frictionless firm-level investment, as discussed in Woodford (2003, Ch. 5). We find that lumpy investment, when combined with price stickiness and market power of firms,can rationalize this assumption. Our main result is in stark contrast with the conclusions obtained by Thomas (2002) in the context of a real business cycle (RBC) model. We use our model to explain the economic mechanism behind this difference in the predictions of RBC and NK theory.

On the sources of business cycles in the G-7

This paper examines sources of cyclical movements in output, inflation and the term structure of interest rates. It employs a novel identification approach which uses the sign of the cross correlation function in response to shocks to catalog orthogonal disturbances. We find that demand shocks are the dominant source output, inflation and term structure fluctuations in six of the G-7 countries. Within the class of demand disturbances, nominal shocks are dominant, but their importance declined after 1982. Furthermore, there are no significant differences in the proportion of term structure variability explained by different structural sources at different horizons.

Disability, capacity for work and the business cycle: An international perspective

An important policy issue in recent years concerns the number of people claimingdisability benefits for reasons of incapacity for work. We distinguish between workdisability , which may have its roots in economic and social circumstances, and healthdisability which arises from clear diagnosed medical conditions. Although there is a linkbetween work and health disability, economic conditions, and in particular the businesscycle and variations in the risk of unemployment over time and across localities, mayplay an important part in explaining both the stock of disability benefit claimants andinflows to and outflow from that stock. We employ a variety of cross?country andcountry?specific household panel data sets, as well as administrative data, to testwhether disability benefit claims rise when unemployment is higher, and also toinvestigate the impact of unemployment rates on flows on and off the benefit rolls. Wefind strong evidence that local variations in unemployment have an importantexplanatory role for disability benefit receipt, with higher total enrolments, loweroutflows from rolls and, often, higher inflows into disability rolls in regions and periodsof above?average unemployment. Although general subjective measures of selfreporteddisability and longstanding illness are also positively associated withunemployment rates, inclusion of self?reported health measures does not eliminate thestatistical relationship between unemployment rates and disability benefit receipt;indeed including general measures of health often strengthens that underlyingrelationship. Intriguingly, we also find some evidence from the United Kingdom and theUnited States that the prevalence of self?reported objective specific indicators ofdisability are often pro?cyclical that is, the incidence of specific forms of disability arepro?cyclical whereas claims for disability benefits given specific health conditions arecounter?cyclical. Overall, the analysis suggests that, for a range of countries and datasets, levels of claims for disability benefits are not simply related to changes in theincidence of health disability in the population and are strongly influenced by prevailingeconomic conditions. We discuss the policy implications of these various findings.

Inequality over the business cycle: Estimating income risk using micro-data on consumption

We use CEX repeated cross-section data on consumption and income, to evaluate the nature of increased income inequality in the 1980s and 90s. We decompose unexpected changes in family income into transitory and permanent, and idiosyncratic and aggregate components, and estimate the contribution of each component to total inequality. The model we use is a linearized incomplete markets model, enriched to incorporate risk-sharing while maintaining tractability. Our estimates suggest that taking risk sharing into account is important for the model fit; that the increase in inequality in the 1980s was mainly permanent; and that inequality is driven almost entirely by idiosyncratic income risk. In addition we find no evidence for cyclical behavior of consumption risk, casting doubt on Constantinides and Duffie s (1995) explanation for the equity premium puzzle.
