Purpose – The objective of the present research is to examine the relationship between consumers' satisfaction with a retailer and the equity they associate with the retail brand. Design/methodology/approach – Retail brand equity is conceptualized as a four-dimensional construct comprising: retailer awareness, retailer associations, retailer perceived quality, and retailer loyalty. Then the associative network memory model is applied from cognitive psychology to the specific context of the relationships between customer satisfaction and consumer-based retailer equity. A survey was undertaken using a convenience sample of shopping mall consumers in an Australian state capital city. The questionnaire used to collect data included an experimental design such that two categories of retailers were included in the study: department stores and specialty stores, with three retailers representing each category. The relationship between consumer-based retailer equity and customer satisfaction was examined using multivariate analysis of variance. Findings – Results indicate that retail brand equity varies with customer satisfaction. For department stores, each consumer-based retailer equity dimension varied according to customer satisfaction with the retailer. However, for specialty stores, only three of the consumer-based retailer equity dimensions, namely retailer awareness, retailer associations and retailer perceived quality, varied according to customer satisfaction level with the retailer. Originality/value – The principal contribution of the present research is that it demonstrates empirically a positive relationship between customer satisfaction and an intangible asset such as retailer equity.

'Social capital' refers to the relationships of trust, communication, and cooperation that facilitate collective action in a community. It is particularly relevant to soil conservation in developing countries, which requires collective efforts to raise awareness of soil degradation, provide effective training in soil conservation practices, and implement soil conservation measures on individual farms. The Landcare Program in the Southern Philippines promotes simple conservation practices in upland environments through establishing and supporting community landcare groups and municipal landcare associations, thus augmenting the social capital of farmers in these locations. An evaluation of the Landcare Program in Barangay Ned, South Cotabato, based on a survey of 313 farm households and case studies of nine landcare groups, shows that, despite extreme isolation and difficult working conditions, farmers responded by rapidly forming landcare groups and a landcare association, and adopting contour barriers on their maize farms. They utilized the bonding social capital inhering in their local communities to build stocks of bridging social capital, linking them to information, training and resources from outside their immediate locality. A logistic regression model of the factors affecting adoption of contour barriers shows that farmers who had undergone the practical, farmer-based training provided by the Landcare Program, and who were members of a landcare group, were significantly more likely to adopt conservation measures. These results confirm the value of investing in social capital to promote soil conservation. Copyright (c) 2005 John Wiley & Sons, Ltd.

This paper studies optinnal public debt in a dynastic model with human capital externalities that cause human capital investment (fertility) to be below (above) its socially optimal level. By reducing fertility and raising human capital investment, the optimal debt can exceed 10% of output for plausible parameterizations.

Em face da complexidade no ambiente de trabalho que exige maior dedicação por parte de seus ocupantes e com uma crescente exigência por desempenho destes indivíduos, o presente estudo teve por objetivo estudar a interdependência de algumas variáveis do comportamento organizacional, testando um modelo conceitual composto do capital psicológico, percepções de suporte e bem-estar no trabalho. Os participantes foram 152 trabalhadores que atuavam na Região Norte (Estado do Tocantins) e Região Sudeste (Estado de São Paulo) em organizações públicas e privadas. Como instrumento para coleta de dados foi utilizado um questionário de autopreenchimento composto de seis escalas que mediram as variáveis da pesquisa. A presente pesquisa se propôs a apresentar, interpretar e discutir as relações entre as variáveis, como também, testar as hipóteses referentes ao modelo conceitual proposto, por meio de uma pesquisa de natureza transversal com abordagem quantitativa, cujos dados coletados foram analisados por aplicação de técnicas estatísticas paramétricas (cálculos de estatísticas descritivas: médias, desvio padrão, teste t e correlações; cálculos de estatísticas multivariadas: análises de regressões lineares múltiplas hierárquicas e stepwise) por meio do software SPSS, versão 18.0. Os resultados obtidos demonstraram que os níveis das três dimensões de bem-estar no trabalho são impactados diretamente pelas percepções de suporte (social no trabalho e organizacional). Confirmou-se também, o capital psicológico como preditor direto das percepções de suporte (social no trabalho e organizacional). Por fim, este trabalho evidenciou que trabalhadores com um capital psicológico elevado tendem a perceber suporte, tanto social no trabalho como organizacional e, por conseguinte, trabalhadores que percebem suporte (social no trabalho e organizacional) tendem a manter vínculos com seu trabalho e com sua organização empregadora, os quais representam bem-estar no trabalho.

Os ativos intangíveis receberam atenção especial de estudiosos nos últimos anos, no contexto organizacional de gestão de pessoas, visto que foram desenvolvidas propostas teóricas para compreendê-los e mensurá-los. Ancorados nesta linha de investigação, encontram-se o capital humano e o capital psicológico. Enquanto o capital humano representa o que os trabalhadores sabem fazer, o capital psicológico compreende um estado mental positivo composto por autoeficácia, esperança, otimismo e resiliência. Este estudo teve, como objetivo geral, analisar as relações entre capital humano e capital psicológico. Tratou-se de um estudo quantitativo do qual participaram 60 trabalhadores, estudantes do último período do Curso de Administração, com idade média de 23,85 anos, sendo a maioria do sexo feminino, solteira e empregada. Os dados para o estudo foram coletados em salas de aula de uma universidade particular, situada na Região do Grande ABC, por meio de um instrumento auto aplicável, contendo uma medida intervalar de capital psicológico com 12 itens, validada para o Brasil, e uma de capital humano com seis questões, sendo duas para medir a dimensão experiência e quatro para aferir educação. Foi criado um banco eletrônico, o qual foi submetido a análises descritivas e de correlação (r de Pearson) por meio do SPSS, versão 19.0. Os resultados revelaram que os participantes detinham um capital humano representado por 4,38 anos médios de experiência de trabalho , e que a maioria (75%) havia revelado possuir no máximo cinco anos neste quesito. Quanto à dimensão educação do capital humano, a maioria (96,70%) não havia concluído nenhum curso de graduação, se dedicou entre 11 a 20 anos aos estudos (81,60%), não realizou intercâmbios de estudos (93%), enquanto 86,70% já incluíram, em seu currículo acadêmico, atividades complementares previstas no Plano Pedagógico do Curso de Administração que cursavam, bem como 73,30% realizaram entre um a três estágios curriculares. As análises indicaram um escore mediano de capital psicológico, acentuado pela dificuldade dos participantes para reconhecerem que estavam em uma fase de sucesso no trabalho e de conseguirem enxergar o lado brilhante das coisas relativas ao trabalho. Ao se investigar as relações entre o capital humano e capital psicológico não foram encontradas correlações significativas. Diante de tais resultados, pareceu provável que os participantes do estudo, por serem predominantemente jovens trabalhadores que ainda não concluíram um curso de graduação, embora tivessem em seu percurso de vida mais de 10 anos dedicados aos estudos e trabalhado por volta de cinco anos em média, ainda não reconheciam, em si, a presença de um consistente capital humano nem psicológico. A ausência de relação observada entre os dois ativos intangíveis preconizados por teóricos como importantes, para que o trabalhador pudesse contribuir com a empresa no alcance de suas metas, pareceu revelar que ainda eram necessários mais estudos e desenvolvimento de teorização, para sustentar não somente as hipóteses acerca de ativos intangíveis, como também permitir identificar a relação de dependência que pudesse existir entre as categorias de capital humano e psicológico.

A dinâmica acelerada dos negócios, as mudanças constantes nas políticas de gestão de pessoas aplicadas por organizações e as complexas interações empresariais em rede parecem ter mudado visivelmente as ênfases dadas por pesquisadores às facetas do comportamento de profissionais que atuam em organizações. Desse modo, dentre tantos outros temas, o planejamento que cada profissional faz acerca de sua saída da organização, denominado intenção de rotatividade, tornou-se novamente um fenômeno de interesse no campo do comportamento organizacional. Atualmente, a alternativa mais aplicada aos estudos do comportamento organizacional tem sido a elaboração de modelos para representar o escopo de uma investigação científica. O objetivo geral deste estudo foi testar um modelo teórico para intenção de rotatividade, analisando-se sua relação com três dimensões de bem-estar no trabalho (satisfação no trabalho, envolvimento com o trabalho e comprometimento organizacional afetivo), moderada por capital psicológico, conceito composto por quatro capacidades psicológicas (eficácia, otimismo, esperança e resiliência). Para análise do modelo foram testadas quatro hipóteses relativas às interações das variáveis nele contidas. Participaram do estudo 85 professores, escolhidos por conveniência, que atuavam em uma universidade na Região do ABCD Paulista. A idade média dos participantes era de 45 anos (DP=11,49), sendo a maioria do sexo masculino, casada, com mestrado concluído e tempo de trabalho variando de 1 a 5 anos. Foi utilizado um questionário de auto preenchimento contendo cinco medidas brasileiras validadas e precisas, as quais aferiram as variáveis do modelo teórico. Os resultados descritivos indicaram que os docentes detêm um quadro de bem-estar no trabalho composto por satisfações maiores com colegas, chefias e tarefas e menores com salários e promoções; desse quadro fazem parte também índices medianos de envolvimento com o trabalho e medianos de compromisso afetivo com a universidade em que atuavam. Entretanto, observou-se que, apesar dos índices medianos das dimensões de bem-estar no trabalho, foi revelada baixa intenção de rotatividade por parte dos docentes. O capital psicológico observado entre os docentes situa-se alto. Análises de correlação pelo r de Pearson informaram índices negativos e significativos entre as três dimensões de bem-estar no trabalho e intenção de rotatividade. Capital psicológico também se mostrou negativa e significativamente correlacionado à intenção de rotatividade. Tais resultados informam que o plano de deixar a universidade onde atuam é inversamente proporcional ao bem-estar vivenciado no trabalho e ao nível de capital psicológico retido pelos docentes. Parece que docentes com elevado capital psicológico e que se sentem bem no trabalho planejam menos deixar a universidade onde atuam, sendo possível interpretar como plausível o inverso. Análises de regressão linear múltipla hierárquica, executadas pelo método enter, informaram que capital psicológico atua como moderador na relação entre bem-estar no trabalho e intenção de rotatividade: foram observadas aumento na predição de intenção de rotatividade quando se adicionou capital psicológico a dois modelos compostos, respectivamente, por satisfação no trabalho e envolvimento com o trabalho. Portanto, o alto nível de capital psicológico poderia potencializar o impacto de satisfação no trabalho e envolvimento com o trabalho sobre a intenção de rotatividade. Por outro lado, no modelo integrado por comprometimento organizacional afetivo o qual revelou maior força de predição sobre intenção de rotatividade, capital psicológico conseguiu reduzir levemente o impacto. Parece que docentes com alto nível de capital psicológico agem sob menos influência do seu compromisso afetivo com a organização quando fazem planos de sair da universidade empregadora. Portanto, os resultados deste trabalho permitem reconhecer que o estado positivo e saudável representado por bem-estar no trabalho poderia ter seu impacto sobre intenção de rotatividade moderado levemente por capital psicológico. Além disso, os resultados descritivos foram discutidos, comparando-os com outros estudos empíricos com professores. Por fim, foi proposta uma pauta para investigações futuras e sugerido criar uma nova linha de pesquisa no Brasil na investigação do papel moderador do conceito integral de capital psicológico nas relações entre constructos do campo do comportamento organizacional, baseada nas lacunas da literatura nacional apontadas nesse estudo.

A necessidade de obter e manter níveis de excelência e de satisfação no trabalho cada vez mais altos leva as organizações a um crescente investimento em modelos de gestão orientados ao suporte dos seus colaboradores. Desse cenário emergem alguns questionamentos: o suporte organizacional impacta na satisfação dos colaboradores? Indivíduos com alto capital psicológico possuem um maior nível de satisfação no trabalho? Buscando responder a essas perguntas, o estudo teve como objetivo comparar e analisar o impacto individual e combinado dos construtos Percepção de Suporte Organizacional e Capital Psicológico na Satisfação no Trabalho. A pesquisa foi realizada com 304 profissionais de empresas públicas e privadas, com escolaridade mínima equivalente ao nível médio, de ambos os gêneros e idades variadas. O instrumento para coleta dos dados foi um questionário de autopreenchimento composto de três escalas: Satisfação no Trabalho EST, Percepção de Suporte Organizacional EPSO e Escala de Capital Psicológico ECP. Para atingir os objetivos propostos no modelo conceitual, foi utilizada a abordagem quantitativa. Os dados foram analisados por modelagem de equação estrutural pelo algoritmo dos mínimos quadrados parciais (PLS). Os resultados demonstraram que as variáveis Percepção de Suporte Organizacional e Capital Psicológico impactam positivamente a variável Satisfação no Trabalho, sendo que a Percepção de Suporte Organizacional exerce maior impacto na Satisfação do Trabalho do que Capital Psicológico.

Analysis of the production efficiency of industrialized countries, questioning whether certain countries perform better than others in producing more output with the same or less inputs, is an example of the importance of estimating production relationships. In order to estimate efficiency one needs an appropriate model for the two major inputs into production activity, namely labour and capital. A physical asset once installed is capable of contributing several years of output. This implies that investments made in previous years must be taken into account in order to produce a measure of the efficiency and productivity for any given year. The purpose of this article is to introduce a dynamic efficiency model and compare the results with previous work on the analysis of efficiency and productivity of OECD countries. The article proposes that dynamic models capture efficiency better than static models.

Recent discussion of the knowledge-based economy draws increasingly attention to the role that the creation and management of knowledge plays in economic development. Development of human capital, the principal mechanism for knowledge creation and management, becomes a central issue for policy-makers and practitioners at the regional, as well as national, level. Facing competition both within and across nations, regional policy-makers view human capital development as a key to strengthening the positions of their economies in the global market. Against this background, the aim of this study is to go some way towards answering the question of whether, and how, investment in education and vocational training at regional level provides these territorial units with comparative advantages. The study reviews literature in economics and economic geography on economic growth (Chapter 2). In growth model literature, human capital has gained increased recognition as a key production factor along with physical capital and labour. Although leaving technical progress as an exogenous factor, neoclassical Solow-Swan models have improved their estimates through the inclusion of human capital. In contrast, endogenous growth models place investment in research at centre stage in accounting for technical progress. As a result, they often focus upon research workers, who embody high-order human capital, as a key variable in their framework. An issue of discussion is how human capital facilitates economic growth: is it the level of its stock or its accumulation that influences the rate of growth? In addition, these economic models are criticised in economic geography literature for their failure to consider spatial aspects of economic development, and particularly for their lack of attention to tacit knowledge and urban environments that facilitate the exchange of such knowledge. Our empirical analysis of European regions (Chapter 3) shows that investment by individuals in human capital formation has distinct patterns. Those regions with a higher level of investment in tertiary education tend to have a larger concentration of information and communication technology (ICT) sectors (including provision of ICT services and manufacture of ICT devices and equipment) and research functions. Not surprisingly, regions with major metropolitan areas where higher education institutions are located show a high enrolment rate for tertiary education, suggesting a possible link to the demand from high-order corporate functions located there. Furthermore, the rate of human capital development (at the level of vocational type of upper secondary education) appears to have significant association with the level of entrepreneurship in emerging industries such as ICT-related services and ICT manufacturing, whereas such association is not found with traditional manufacturing industries. In general, a high level of investment by individuals in tertiary education is found in those regions that accommodate high-tech industries and high-order corporate functions such as research and development (R&D). These functions are supported through the urban infrastructure and public science base, facilitating exchange of tacit knowledge. They also enjoy a low unemployment rate. However, the existing stock of human and physical capital in those regions with a high level of urban infrastructure does not lead to a high rate of economic growth. Our empirical analysis demonstrates that the rate of economic growth is determined by the accumulation of human and physical capital, not by level of their existing stocks. We found no significant effects of scale that would favour those regions with a larger stock of human capital. The primary policy implication of our study is that, in order to facilitate economic growth, education and training need to supply human capital at a faster pace than simply replenishing it as it disappears from the labour market. Given the significant impact of high-order human capital (such as business R&D staff in our case study) as well as the increasingly fast pace of technological change that makes human capital obsolete, a concerted effort needs to be made to facilitate its continuous development.

In this paper we propose a data envelopment analysis (DEA) based method for assessing the comparative efficiencies of units operating production processes where input-output levels are inter-temporally dependent. One cause of inter-temporal dependence between input and output levels is capital stock which influences output levels over many production periods. Such units cannot be assessed by traditional or 'static' DEA which assumes input-output correspondences are contemporaneous in the sense that the output levels observed in a time period are the product solely of the input levels observed during that same period. The method developed in the paper overcomes the problem of inter-temporal input-output dependence by using input-output 'paths' mapped out by operating units over time as the basis of assessing them. As an application we compare the results of the dynamic and static model for a set of UK universities. The paper is suggested that dynamic model capture the efficiency better than static model. © 2003 Elsevier Inc. All rights reserved.

Contrary to the long-received theory of FDI, interest rates or rates of return can motivate foreign direct investment (FDI) in concert with the benefits of direct ownership. Thus, access to investor capital and capital markets is a vital component of the multinational’s competitive market structure. Moreover, multinationals can use their superior financial capacity as a competitive advantage in exploiting FDI opportunities in dynamic markets. They can also mitigate higher levels of foreign business risks under dynamic conditions by shifting more financial risk to creditors in the host economy. Furthermore, the investor’s expectation of foreign business risk necessarily commands a risk premium for exposing their equity to foreign market risk. Multinationals can modify the profit maximization strategy of their foreign subsidiaries to maximize growth or profits to generate this risk premium. In this context, we investigate how foreign subsidiaries manage their capital funding, business risk, and profit strategies with a diverse sample of 8,000 matched parents and foreign subsidiary accounts from multiple industries in 38 countries.We find that interest rates, asset prices, and expectations in capital markets have a significant effect on the capital movements of foreign subsidiaries. We also find that foreign subsidiaries mitigate their exposure to foreign business risk by modifying their capital structure and debt maturity. Further, we show how the operating strategy of foreign subsidiaries affects their preference for growth or profit maximization. We further show that superior shareholder value, which is a vital link for access to capital for funding foreign expansion in open market economies, is achieved through maintaining stability in the rate of growth and good asset utilization.

This paper investigates competition between chain-stores and independents in the UK opticians' industry, using the relationship between the number of outlets present in a local market and the market size. Chain-stores are shown to have a significant effect on local market competition. In addition, the empirical approach is extended to allow inferences on the nature and extent of product differentiation. The results are broadly consistent with a model of vertical product differentiation in which chain-stores adopt national pricing strategies. The evidence suggests that the nature of competition between independent retailers depends on whether a chain-store is present.

In this work the solution of a class of capital investment problems is considered within the framework of mathematical programming. Upon the basis of the net present value criterion, the problems in question are mainly characterized by the fact that the cost of capital is defined as a non-decreasing function of the investment requirements. Capital rationing and some cases of technological dependence are also included, this approach leading to zero-one non-linear programming problems, for which specifically designed solution procedures supported by a general branch and bound development are presented. In the context of both this development and the relevant mathematical properties of the previously mentioned zero-one programs, a generalized zero-one model is also discussed. Finally,a variant of the scheme, connected with the search sequencing of optimal solutions, is presented as an alternative in which reduced storage limitations are encountered.

How does a firm choose a proper model of foreign direct investment (FDI) for entering a foreign market? Which mode of entry performs better? What are the performance implications of joint venture (JV) ownership structure? These important questions face a multinational enterprise (MNE) that decides to enter a foreign market. However, few studies have been conducted on such issues, and no consistent or conclusive findings are generated, especially with respect to China. It’s composed of five chapters, providing corresponding answers to the questions given above. Specifically, Chapter One is an overall introductory chapter. Chapter Two is about the choice of entry mode of FDI in China. Chapter Three examines the relationship between four main entry modes and performance. Chapter Four explores the performance implications of JV ownership structure. Chapter Five is an overall concluding chapter. These empirical studies are based on the most recent and richest data that has never been explored in previous studies. It contains information on 11,765 foreign-invested enterprises in China in seven manufacturing industries in 2000, 10,757 in 1999, and 10,666 in 1998. The four FDI entry modes examined include wholly-owned enterprises (WOEs), equity joint ventures (EJVs), contractual joint ventures (CJVs), and joint stock companies (JSCs). In Chapter Two, a multinominal logit model is established, and techniques of multiple linear regression analysis are employed in Chapter Three and Four. It was found that MNEs, under the conditions of a good investment environment, large capital commitment and small cultural distance, prefer the WOE strategy. If these conditions are not met, the EJV mode would be of greater use. The relative propensity to pursue the CJV mode increases with a good investment environment, small capital commitment, and small cultural distance. JSCs are not favoured by MNEs when the investment environment improves and when affiliates are located in the coastal areas. MNEs have been found to have a greater preference for an EJV as a mode of entry into the Chinese market in all industries. It is also found that in terms of return on assets (ROA) and asset turnover, WOEs perform the best, followed by EJVs, CJVs, and JSCs. Finally, minority-owned EJVs or JSCs are found to outperform their majority-owned counterparts in terms of ROA and asset turnover.

This thesis investigates the pricing-to-market (PTM) behaviour of the UK export sector. Unlike previous studies, this study econometrically tests for seasonal unit roots in the export prices prior to estimating PTM behaviour. Prior studies have seasonally adjusted the data automatically. This study’s results show that monthly export prices contain very little seasonal unit roots implying that there is a loss of information in the data generating process of the series when estimating PTM using seasonally-adjusted data. Prior studies have also ignored the econometric properties of the data despite the existence of ARCH effects in such data. The standard approach has been to estimate PTM models using Ordinary Least Square (OLS). For this reason, both EGARCH and GJR-EGARCH (hereafter GJR) estimation methods are used to estimate both a standard and an Error Correction model (ECM) of PTM. The results indicate that PTM behaviour varies across UK sectors. The variables used in the PTM models are co-integrated and an ECM is a valid representation of pricing behaviour. The study also finds that the price adjustment is slower when the analysis is performed on real prices, i.e., data that are adjusted for inflation. There is strong evidence of auto-regressive condition heteroscedasticity (ARCH) effects – meaning that the PTM parameter estimates of prior studies have been ineffectively estimated. Surprisingly, there is very little evidence of asymmetry. This suggests that exporters appear to PTM at a relatively constant rate. This finding might also explain the failure of prior studies to find evidence of asymmetric exposure in foreign exchange (FX) rates. This study also provides a cross sectional analysis to explain the implications of the observed PTM of producers’ marginal cost, market share and product differentiation. The cross-sectional regressions are estimated using OLS, Generalised Method of Moment (GMM) and Logit estimations. Overall, the results suggest that market share affects PTM positively.Exporters with smaller market share are more likely to operate PTM. Alternatively, product differentiation is negatively associated with PTM. So industries with highly differentiated products are less likely to adjust their prices. However, marginal costs seem not to be significantly associated with PTM. Exporters perform PTM to limit the FX rate effect pass-through to their foreign customers, but they also avoided exploiting PTM to the full, since to do so can substantially reduce their profits.
