This paper analyses the presence of financial constraint in the investment decisions of 367 Brazilian firms from 1997 to 2004, using a Bayesian econometric model with group-varying parameters. The motivation for this paper is the use of clustering techniques to group firms in a totally endogenous form. In order to classify the firms we used a hybrid clustering method, that is, hierarchical and non-hierarchical clustering techniques jointly. To estimate the parameters a Bayesian approach was considered. Prior distributions were assumed for the parameters, classifying the model in random or fixed effects. Ordinate predictive density criterion was used to select the model providing a better prediction. We tested thirty models and the better prediction considers the presence of 2 groups in the sample, assuming the fixed effect model with a Student t distribution with 20 degrees of freedom for the error. The results indicate robustness in the identification of financial constraint when the firms are classified by the clustering techniques.  相似文献

This article focuses on understanding rural life and how agrarian everyday life changes as a consequence of the radical socio‐economic transformations that, across the world, have accompanied rural communities in their transition from economies of subsistence to industrial production, and, in some areas, from there to providers of service to the tourism‐oriented leisure economy. In the last century in the Alt Urgell District (Spanish Pyrenees), many communities went from a production model based on subsistence farming and livestock breeding first to a specialization in milk production and later to tourism. The industrialization of milk production, the radical transformation of the scale of their operations, and the monetization of life transformed the identity and structure of these communities. The subsequent transformation of many of these farms to accommodate the leisure industry changed the shape of these households again. This paper reflects on how science, governance, commodification, and technology played a role on the transformation of the rural mountain areas, their people, and their everyday life.  相似文献

The consumer acceptability of a Philippine cultivar quick-cooking rice (QCR) as food for use in a disaster was studied. Test feeding in an evacuation centre involved random selection of 50 young adults and adult evacuees, rehydration of QCR and distribution of test rice samples for sensory evaluation test. The sensory evaluation results showed that more than 90% of the evacuee participants found the colour, texture, taste and overall qualities of the rehydrated QCR to be acceptable. Eighty per cent of the participants described the rehydrated rice to be adequately soft and neither undercooked nor overcooked. The test QCR samples were described by the community kitchen personnel of the evacuation centre as easy to prepare, requiring minimum cooking time and exhibiting homogeneity in doneness when cooked.  相似文献

The paper studies the operation of the mixed pension system established in Argentina in 1994. It points to the limitations that the new system has encountered to achieve some of the most important objectives of pension policy and pension reform. The analysis looks at the mechanisms affecting pension system performance, with particular attention to the way in which the new pension rules have interacted with the local macroeconomic, social, and political context. The empirical analysis of this experience is oriented to provide lessons for Argentina’s future reforms, as well as for many Latin American countries with similar pension arrangements.  相似文献

The measurement of social and psychological phenomena has been advanced by recent progress in the fields of behavioural economics and hedonic psychology. In addition, the increased interest in understanding how individuals perceive their own quality of life, has led to investigating the relations between various macro and individual level variables, generically subsumed as happiness. For many “happiness is considered to be an ultimate goal in life” and it plays an important role in the way people perceive the overall society they live in. Therefore, social scientists and behavioural economists are now stressing the importance of well-being measures, related to people’s evaluations of their quality of life in addition to economic indicators. In the transport sector, project evaluation is mainly based on cost–benefit analyses using economic indicators. However, any provided transportation project/service impacts the quality of the travel experience, the well-being of travellers and their travel behaviour. Competitiveness of modes may be also affected by the promotion of derived or experienced travellers’ well-being. Thus, existing behavioural travel choice models should be enhanced with regards to their behavioural validity incorporating the impacts of travelling happiness/ satisfaction. This study aims to understand and model the impact of stated (anticipated) happiness in the decision choice between a private transport mode—car, and a public transport mode—metro.  相似文献

Using firm‐level data from 2006 to 2013 for a set of developing countries, we examine the effects of financial development on innovation. Financial development boosts innovation by improving resource allocation and investment in strategic sectors as well as facilitating technology to promote growth. Using binary response models and instrumental variable techniques to correct for endogeneity, we find robust but puzzling results. Contrary to most of the existing literature, financial development has a negative effect on the probability of a firm to innovate in developing countries. This effect is conditional on firm size, and only larger firms benefit from financial development. These results are robust to different measures of financial development and econometric specifications. We argue that this is a result of the design of the financial system in regard to the lack of capital and institutional system. Consequently, developing countries should first generate appropriate institutional conditions if they want financial development to spur growth through innovation.  相似文献

This paper report results of an analysis of the demand for energy in the Mexican transport sectors, focusing on the railroad, air transport and motor vehicle modes. The approach is an econometric one with emphasis placed on the structure for each mode. For two of the modes a two-stage approach is employed where in the first stage demands for services from the particular mode are modeled, and in the second stage demand is treated as a derived demand from these transport services. For the motor vehicle mode, gasoline demand is considered as the product of gasoline consumption per vehicle times the total number of vehicles, and then these components are related to economic and structural variables. Diesel demand of motor vehicles is modeled in a more reduced from approach. The principal finding is that changes in income play a more important role in affecting energy demand than do changes in energy prices, especially in the railroad and air transport sectors. For the gasoline and diesel fuel demand in the monitor vehicle sector, however, price is of substantial importance.  相似文献

Non-governmental charities operate in a competitive market and survive with funding from membership fees and donations from supporters. Knowing and motivating potential donors has become increasingly important. Advertising is one of the key means of communication used by these organizations. This paper reports a pilot study to explore the influence of image valence in advertising on one’s attention and intention to donate. The study consists of an experiment wherein data processing is based on eye tracking and an electroencephalogram. The results show that negative images get more attention than text and logos. No differences were found with regard to gender and intention to donate in terms of attention paid to the advertising images. However, women do show greater willingness to make a donation. Finally, strategies adapted to charitable NGOs are discussed in the conclusions.  相似文献

Judicial Reform   总被引:1,自引:0,他引:1  
A review of the evidence on judicial reform across countriesshows that those seeking to improve economic performance shouldnot focus on judicial efficiency alone but on independence aswell. It also shows that the level of resources poured intothe judicial system and the accessibility of the system havelittle impact on judicial performance. Most of the problem ofjudicial stagnation stems from inadequate incentives and overlycomplicated procedures. Incentive-oriented reforms that seekto increase accountability, competition, and choice seem tobe the most effective in tackling the problem. But incentivesalone do not correct systematic judicial failure. Chronic judicialstagnation calls for simplifying procedures and increasing theirflexibility.   相似文献

The article analyzes the transmission mechanism of monetary policy in light of microeconomic theory. We address the influence of microeconomic factors on the transmission of monetary policy while taking into account the contributions of conventional price formation and competition theory and heterodox microeconomic theories, including work inspired by the post Keynesians. We found a multiplicity of results regarding changes in price levels and inflation derived from shifts in demand and costs. These results challenge the conventional view, which postulates a single behavior in the circuit from changes in interest rates to demand, prices, and inflation. We conclude that microeconomic and macroeconomic aspects should be integrated to properly explain monetary policy and analyze its effects and transmission mechanism.  相似文献
