This paper investigates substitution among such alternate fuels as coal, natural gas, and electricity during the actual oil price increases of 1970s. These substitution adjustments are assumed to be dynamic and modelled by a partial adjustment structure. This dynamic structure is incorporated into a translog cost technology. Short- and long-run price elasticities are estimated by identifying inter- and intra-industry variations. The models are estimated with a sample of 88 pooled observations, including distillate and residual oils purchased by eleven 2-digit manufacturing groups (1974-81). Models are estimates are strictly negative. These own price elasticities range from (long-to short-run) –2.93 to –2.55 for distillate oil, –0.698 to – 1.53 for residual oil, –0.533 to 0.011 for coal, –0.235 to –0.213 for natural gas, to –0.888 to –0.845 for electricity. Estimastes of both short-run and long-run cross-price elasticities suggest that coal and electric energy are the prominent substitutes for fuel oils. While the relationship between the latter and natural gas remains largely complementary.  相似文献

We examine the stock market reaction to 1227 inter-corporate ordinary business contract announcements reported by Dow Jones between January 1, 1990 and December 31, 2001. Around contract announcement dates, we find statistically significant positive average abnormal returns and abnormal trading volume for contractors, but insignificant positive abnormal returns and negative abnormal volume for contractees. Cross-sectionally, contract announcement period returns are higher for contractors who are small relative to the contract size, have higher return volatility, larger market-to-book ratios and higher profitability. The announcement period returns of contract-awarding firms are not significant and are only marginally related to cross-sectional explanatory factors. The results are consistent with two explanatory stories: contractor quasi-rents induced by the winner's curse and information signalling about contractor production costs. The results are not consistent with perfect competition, with contracts having positive net present values for both parties, and with a version of incomplete contracting theory.  相似文献

It is not enough in today's environment to just meet customers' expectations--we must exceed them. Therefore, one must learn what constitutes expectations. These needs have expanded during the past few years from just manufacturing the product and looking at the outcome from a provincial standpoint. Now we must understand and satisfy the entire supply chain. To manage this process and satisfy the customer, the process now involves the supplier, the manufacturer, and the entire distribution system.  相似文献

We develop a bid‐ask spread estimator from daily high and low prices. Daily high (low) prices are almost always buy (sell) trades. Hence, the high–low ratio reflects both the stock's variance and its bid‐ask spread. Although the variance component of the high–low ratio is proportional to the return interval, the spread component is not. This allows us to derive a spread estimator as a function of high–low ratios over 1‐day and 2‐day intervals. The estimator is easy to calculate, can be applied in a variety of research areas, and generally outperforms other low‐frequency estimators.  相似文献

Models of firm microstructure are becoming now a standard building block in macroeconomics, trade, and development. This literature builds on the recognition that firm heterogeneity and the allocation of resources across firms plays a key role in determining aggregate productivity and the gains from trade. Barriers to the efficient allocation of resources across firms have been recently recognized to play a key role in economic development. This paper focuses on this methodological contribution, the link between firm microstructure and economic aggregates.  相似文献

The author dissects, with great acuteness, the issues of convergence in financial performance dynamics in the African continent through the lenses of stock market capitalization, value traded, turnover, and number of listed companies. The empirical evidence is premised on 11 homogeneous panels based on regions (Sub-Saharan and North Africa), income levels (low, middle, lower-middle, and upper-middle), legal origins (English common law and French civil law), and religious dominations (Christianity and Islam). Findings provide partial support for the existence of absolute convergence in some dynamics. Only Sub-Saharan Africa reveals conditional convergence in relation to per capita number of listed companies. The speed of convergence for the most part is between 12% and 28% per annum. As a policy implication, countries should work toward adopting common institutional and structural characteristics that favor stock market development.  相似文献

State regulation of rates is sometimes used as a means to make automobile insurance more affordable to consumers by restricting insurer profits and pricing practices. Incentive distortions arising from this type of rate regulation might lead to higher accident rates and higher insurance loss costs. Annual state‐level panel data for the time period 1980–1998 are used to investigate these effects, using empirical methods that recognize the endogenous determination of states’ regulatory choices. Results suggest that rate regulation that systematically suppresses (some or all) drivers’ insurance premiums is associated with significantly higher average loss costs and higher insurance claim frequency.  相似文献

It is widely believed that international financial reporting standards (IFRS) have been adopted in many countries, at least for the consolidated reporting of listed companies. However, in nearly all cases, what the rules require is some national or supranational version of IFRS. This might create problems for investor confidence and comparability. We examine what companies and auditors report concerning compliance with IFRS, focusing on the first full year of IFRS reporting by companies in the stock market indices of four major European countries and Australia. We find that, even when companies were complying with IFRS, they were generally not saying so, which seems to miss part of the point of the 35‐year project on international harmonization. In a small number of cases, auditors provided dual reports: on full IFRS in addition to the mandated reference to national GAAP where the latter corresponds with full IFRS. These cases were found only in Germany and the United Kingdom, and mainly related to companies that filed with the Securities and Exchange Commission as foreign private issuers. We propose explanations for the general lack of dual reports and for the exceptions. We call for widespread adoption of dual reporting where a plain report on IFRS is not yet possible.  相似文献
