The introduction of the flex-fuel cars in the Brazilian market in 2003 changed considerably the consumer decision-making process. Prior to this date, it was necessary to choose the automobile type only by gasoline or by ethanol fuel; today it is possible to choose a car type with both fuel options. This flexibility generates economic advantages for his owner, but what are the financial benefits of a flex-fuel car in comparison with a car using only gasoline? Geographically, where is the owner of the benefits from this flexibility located? This article presents an empirical application of the Real Options Theory in the analysis of the flex-fuel car option for five geographic Brazilian regions: Northern, Northeastern, Central-Western, Southeastern and Southern. The regional price differences as well as the consumer preferences of these regions were met. For this purpose, historical fuel prices were considered stochastic and following a Mean Reverting Stochastic process. The prediction and option values were generated by a Monte Carlo simulation. The results indicated that the option embedded on the Brazilian flex-fuel car adds considerable value to the owner in all regions and car models considered, with the Southeastern Region receiving most benefits by the flex option.  相似文献

This paper is concerned with the ownership structure of corporate debt from an institutional perspective. An attempt is made to identify the factors affecting bank debt use from an international sample of companies from Austria, Germany, Japan, Belgium, France, Italy, Holland, Spain, Portugal, Finland, Sweden and the USA. The results show that bank debt depends both on factors specific to each company and on institutional features of each country. More exactly, it is found that bank loans are related to firm size, to the quality and risk of the projects, and to the collateral. It is also found that a number of legal-institutional factors are impacting on the source of firms’ debt, such as creditor protection, firm disclosure requirements and law enforcement.  相似文献

This article presents three different unit root tests for panel data, the main objective is to find the level of internal integration market through the purchasing power parity (PPP) evidence, based in the Balassa–Samuelson approach. Thus, eight kinds of markets, as tradable and nontradable goods for 16 main Mexican cities during a 21 year period have been contrasted. While two tests showed the PPP validity for seven markets, the other rejected it. The results obtained moreover feed the present controversy about which test is most appropriate to test the PPP, as soon as it is highlighted new elements emerge to explain the half-life analysis.  相似文献

Norway has among the most generous family policies in the world. The most recent is the cash-for-care reform, which was implemented in 1998. We answer two main questions in this article: What is the level of the family gap in such a generous regime and how has it developed as a consequence of the latest reform? Results suggest that the family gap is rather modest in Norway compared to many other countries and we find no evidence of a worsening of the gap in recent years. A positive interpretation of these results is that the Norwegian labour market is fairly flexible, in the sense that it seems to be able to absorb even more generous family policies.  相似文献

This article proposes and estimates an inflation indicator for the European Monetary Union (EMU). This indicator is set up so that it is contemporarily not affected by the changes in price differentials among EMU countries. The results show that the Monetary Union Index of Consumer Prices (MUICP), which is the inflation measure that the European Central Bank (ECB) takes as a reference for monetary policy purposes, could be understating the value of the inflation in the euro zone. It is also concluded that regional peculiarities are fundamental in the evolution of prices in the different EMU countries.  相似文献

This study empirically examines the business cycle behaviour of public consumption and its main components, the public wage bill (including its breakdown into compensation per employee and public employment) and intermediate consumption, in the euro area aggregate, euro area countries and a group of selected non-euro area Organization for Economic Co-operation and Development (OECD) countries (Denmark, Sweden, the UK, Japan and the US). It looks across a large number of variables and methods, using annual data from 1960 to 2005. It finds robust evidence supporting that public consumption, wages and employment co-move with the business cycle in a pro-cyclical manner with 1–2 year lags, notably for the euro area aggregate and euro area countries. The findings reflect mainly the correlation between cyclical developments, but also point to an important role of pro-cyclical discretionary fiscal policies.  相似文献

In this article, we examine the convenience of dollarization for Ecuador today. As Ecuador is strongly integrated financially and commercially with the United States, the exchange rate pass-through should be zero. However, we sustain that rising rates of imports from trade partners other than the United States and subsequent real effective exchange rate depreciations are causing the pass-through to move away from zero. Here, in the framework of the Vector Error Correction Model, we analyse the impulse response function and variance decomposition of the inflation variable. We show that the developing economy of Ecuador is importing inflation from its main trading partners, most of them emerging countries with appreciated currencies. We argue that if Ecuador recovered both its monetary and exchange rate instruments, it would be able to fight against inflation. We believe such an analysis could be extended to other countries with pegged exchange rate regimes.  相似文献

There is conflicting evidence concerning the impact of macroeconomic conditions on suicide rates. To help resolve this pertinent question, we present evidence using Canadian data. We estimate feasible generalized least squares models of annual gender-specific suicide rates in the working age population (aged 25–64) using data from each of the 10 Canadian provinces over the period 1982 to 2007. We allow for heteroscedasticity across provinces and first-order autocorrelation common to all provinces. We posit that suicide rates in this population are a function of macroeconomic conditions (current and lagged unemployment rates and real per capita GDP) and other determinants that might be correlated with macro conditions, such as physician supply. We find that different factors affect suicide rates across genders and that some of the results are sensitive to the specification of the model we use and the regressors included. Generally, economic conditions affect men more than women; suicide rates are counter-cyclical and a higher supply of psychiatrists in a province is correlated with lower suicide rates.  相似文献

The World Bank has suggested the need to enhance Information and Communication Technology skills in all sectors because a 10% increase in internet connectivity was found to boost GDP growth by 1.38%. Simultaneously, the OECD argued that high internet access rates generate a 2% increase in GDP. Because the internet positively affects economic growth, we investigated the relationship between an economically active population, human capital and technology to evaluate these effects in Mexico. A data series from 1991 to 2010 was analysed in three stages according to the least-squares method. A Cobb–Douglas function under the Solow model was considered. Technology and internet access were found to positively affect top-level students and graduate students and thus contribute to the global innovation index.  相似文献

This note acknowledges and corrects a programming error in our paper “Inequality of Opportunity in Brazil” (Review of Income and Wealth, 53(4), 585–618, 2007). Once the error is corrected, our bounds approach to the identification of individual model parameters in the presence of omitted variable biases is much less useful than indicated in the original paper. In the specific context of the measurement of inequality of opportunity, this implies that the decomposition of overall inequality of opportunity into direct and indirect effects is not reliable. However, the parametric approach introduced in our paper remains useful for obtaining a lower‐bound estimate of overall ex‐ante inequality of opportunity, as proposed by Ferreira and Gignoux (2011).  相似文献
