This paper studies the effect of station density on prices in the retail gasoline market in the Czech Republic. We estimate the impact of the number of competing stations in various driving-distance ranges around each station on prices. We find that station density has a negative effect on prices; the effect decreases with distance and is statistically significant up to six kilometers. This suggests that the retail gasoline market is local rather than national. 相似文献

The general consensus in the volatility forecasting literature is that high-frequency volatility models outperform low-frequency volatility models. However, such a conclusion is reached when low-frequency volatility models are estimated from daily returns. Instead, we study this question considering daily, low-frequency volatility estimators based on open, high, low, and close daily prices. Our data sample consists of 18 stock market indices. We find that high-frequency volatility models tend to outperform low-frequency volatility models only for short-term forecasts. As the forecast horizon increases (up to one month), the difference in forecast accuracy becomes statistically indistinguishable for most market indices. To evaluate the practical implications of our results, we study a simple asset allocation problem. The results reveal that asset allocation based on high-frequency volatility model forecasts does not outperform asset allocation based on low-frequency volatility model forecasts. 相似文献

We show that business education/occupations have expanded and that technical education/occupations have contracted in the Czech Republic and Poland since 1990. We interpret these changes as an adjustment necessary for their transition to a market economy. We do not find the same pattern in Hungary, which we attribute to the earlier timing of its transition. We construct an aggregate model in which labour reallocates in response to changing demand structure. When calibrated with the Czech and Polish data, the model generates a large movement of workers with technical education and experience into business occupations in the early 1990s. The discounted sum of output loss due to the gap between the demand structure and the composition of existing human capital amounts to between 8 and 40 percent of 1990 GDP. 相似文献

This paper uses data from the 1991 sweep of the National Child Development Study (NCDS) and the 1998 Labour Force Survey (LFS) to provide a comprehensive analysis of the labour market returns to academic and vocational qualifications. The results show that the wage premia from academic qualifications are typically higher than from vocational qualifications. However, this gap is reduced somewhat, when we control for the amount of time taken to acquire different qualifications. This is particularly important for vocational courses, which generally take shorter time periods to complete. In the paper we also investigate how returns vary by gender, subsequent qualifications, and the natural ability of individuals. Finally, by comparing the NCDS results with those from the LFS, we estimate the bias that can result from not controlling for factors such as ability, family background and measurement error. The results reveal that the estimated returns in the NCDS equations controlling for ability, family background and measurement error are similar to the simple OLS estimates obtained with the LFS, which do not control for these factors. This suggests that the biases generally offset one another. 相似文献

ABSTRACT The paper makes three contributions to the understanding of the post-crisis European banking governance. First, it offers a more comprehensive approach to banking governance, beyond the Banking Union, through its concept of ‘New European Banking Governance’ (NEBG) that incorporates EU state aid rules and fiscal regulations. Second, it considers the impact of NEBG on democratic institutions and processes in EU member states, an under-researched topic in the literature on European banking governance. Finally, through its in-depth case study of Slovenia it considers the NEBG in relation to peripheral Eurozone states. It argues that the post-crisis banking governance framework of the EU not only severely constrained the Slovenian state in its policy choices but rearranged its policy-making institutions in a way that restricted and continues to restrict democratic banking policy formation. 相似文献

We develop a new option-based method for the valuation of mortgage insurance contracts in closed form in an economy where
agents are risk neutral. While the proposed valuation method is general and can be used in any market, it may be particularly
useful in emerging market economies where other existing methods may be either inappropriate or are too difficult to implement
because of the lack of relevant data. As an application, we price a typical Serbian government-backed mortgage insurance contract. 相似文献
