Renegotiations are often claimed to be the major pitfall in public–private partnership projects. In fact, the literature and empirical evidence suggest a bias toward favoring concessionaires, although there are well-known examples of harmful unilateral decisions by governments. This article establishes a distinction between structural renegotiations (with changes in the risk-sharing agreement) and nonstructural renegotiations (without shifting risk) and analyzes the implications of structural renegotiations in a road concession by comparing the ex ante and ex post financial implications for government, concessionaire, and users. The selected project is one that started as a shadow toll and was later changed to real toll. The analysis shows that the renegotiation essentially transferred costs to the users. The financial burden for the government decreased and the internal rate of return (IRR) of the concessionaire increased slightly although the overall risk profile of the concession decreased. The users supported a 40% higher cost, and the system gained an additional cost component (the electronic tolling system). Overall the global financial costs increased 40% when compared with the initial regime. The article also sets out some discussions and implications for policymakers.  相似文献

This study analyzes the effect of informational clues and Chef-Cuisine congruence, and their relation to advertisements for a Japanese restaurant. Two experiments were conducted with 171 consumers. Findings supported the following: Congruence between a Japanese restaurant and Japanese Chef results in higher approval ratings than the combination of Japanese restaurant with Brazilian Chef. However, if the advertisement states that the restaurant has won an award, then Chef-restaurant congruence is no longer an important factor in consumers’ evaluations.  相似文献

This article examines the relationship between the monetary policy implemented by the Central Bank of Brazil and the stock market. We implement event study analysis and analyze the effect of the anticipated and unanticipated components of monetary policy decisions on the returns of the IBOVESPA index and 53 stocks. We find that monetary policy has a significant effect on the stock market, but is only responsible for a small proportion of market variation. The analysis at the sector level with expected returns identifies that the financial sector is the most affected by this policy, whereas with excess returns only industrial goods are significantly affected. Moreover, individual assets respond in a rather heterogeneous fashion to monetary policy; however, when we look at excess returns, we identify a reduction in the intensity and in the number of companies impacted by monetary policy. Finally, the monetary shock is explained by unanticipated variations in the unemployment rate, in the Industrial Production Index, in the General Market Price Index, and in the Broad Consumer Price Index.  相似文献

Occurrences of financial distress (FD) are not readily obvious yet can span several periods. This paper examines episodes of FD using industry‐relative (IR) firm‐/ accounting‐, market‐ and macro‐level information. Mixed logit regressions reveal that firm‐ and market‐based measures, as well as macro‐level variables explain the likelihood of FD in 263 publicly listed non‐banking firms in the Philippines during the period 1995 to 2018. Rates of identification of firms in financial distressed states of close to 69 percent are obtained at a cutoff probability of 0.30 in the model with time‐varying intercept and slope. This study shows the importance of recognizing heterogeneous firm behavior. The ability to more accurately predict the probability of FD and to determine the financial health of firms can help financial institutions in allocating funds and policy makers in predicting crises episodes.  相似文献

This paper analyses the relationship between politics and performativity of economics in the emergence of markets for biodiversity offsets. While the role of economics in constructing markets has been demonstrated by sociology and social studies of science, it has also become apparent that politics plays an important role in the material outcome of economic experiments. Two case studies of the creation of markets for biodiversity offsets are analysed, in the United States and England. The findings suggest that the creation of both markets is rooted in the language, concepts and models of economics. Politics, on the other hand, functions as a mediator of the material expression of those models. Through this mediation effect, similar economic models are performed differently, resulting in a variety of markets. This suggests that the material outcomes of processes of market creation are not defined at the outset, but can be influenced by political processes.  相似文献

In this article, we focus on consumption in a context of economic hardship. From an empirical perspective, and using a qualitative methodology, we show how disadvantaged individuals and households maintain a level of consumption commensurate with the society in which they are integrated through a type of consumption conceived of here as “resilient”. Resilient consumption is characterized by being a type of expenditure oriented towards maintaining the role of consumer, that is, maintaining a minimum level of purchasing power, modifying to this end both the level and the structure of consumption, both of which are key elements in the resilience process. We identify five main strategies used by households that modify and restructure the consumption of basic goods and necessities in response to economic hardship. Key resilient consumption strategies include: reduction (cutting down on spending), substitution (replacement of one difficulty with another), compensation (pseudo‐consumption or reduced usage), transference (meta‐resilience) and integration (reinterpretation of difficulties as opportunities). We conclude that although consumption is a naturally resilient behaviour, in a crisis context, resilient practices focus on maintaining acquisition capacity in spite of reduced income.  相似文献

Globally, society has been facing several and growing health problems, which increased the importance of efforts towards social change. In this context, using social marketing to create and implement programs that foster behavioural change has increased in the public health community. One of the health problems that society has been facing is the unceasing need for blood products, so the subject of blood donation became an important research topic in the area of social marketing, as social marketing strategies can contribute to solving this problem. It is essential to understand the factors that motivate individuals to donate blood, to enhance the recruitment and retention of blood donors. Our study aims at evaluating the key personality factors that influence blood donation behaviour to reach a higher understanding of what concerns this global issue. The method used to analyse the data is ANOVA. We conclude that the Personality of potential donors is significantly different from the non-donors' regarding Openness to Experience and Agreeableness. These results suggest that potential donors might perceive blood donation, as well as the associated barriers, differently from non-donors. Based on our findings, we suggest some perspectives for future research in this area.  相似文献

The economic impacts of animal disease outbreaks have been widely discussed in the literature. Most authors have centred their attention on estimating the direct costs. Recent studies have shown that the indirect economic effects might lead to equal or even higher welfare losses. This study aims to contribute to this field of research by assessing the effect of an animal disease outbreak on food market price dynamics in Mexico, accounting for the potential effect of an antitrust intervention. We employ a regime‐dependent vector error correction model and a connected scatterplot analysis. The results show that both the outbreak and the antitrust intervention caused structural breaks in food market price dynamics between producers and consumers, reflected in an increase in the absolute component of the marketing margin, with serious food security implications.  相似文献

Successful development processes involve not only ‘sectorial structural change’, shifts of factors between different productive sectors, but also, ‘institutional structural change’, shifts of factors from unproductive activities (predation) to productive ones. This paper analyzes the feedback process between the sectorial and the institutional structural changes in a model in which the labor share in agriculture is lower than in other sectors. Along the transition sectorial structural change emerges: employment in agriculture declines. Consequently, total labor share increases, raising the reward for working (while discouraging predation) and so, fostering institutional structural change. This, in turn, encourages capital accumulation, promoting sectorial structural change. This feedback mechanism widens differences in productivity and institutions among countries. Whereas zero-cost policies aimed to build institutions have positive effects, costly policies have uncertain effects due to complex feedback mechanisms.  相似文献
