We suggest a theory of quality dualism, defined in terms of the gap between the highest quality good produced in the informal sector and the lowest quality produced in the formal sector. We develop a model of vertically differentiated products, in which firms producing in the formal and informal sectors face different factor prices, and have a relative advantage in the manufacture of different qualities. We then use the model to examine the cyclical behavior of the respective sizes of the two sectors. Finally, we point out that factor price changes, which reduce or increase the size of the informal sector, may have the same or opposite effect on the degree of dualism in the economy. 相似文献

3G,是英文3rd Generation的缩写,指第三代移动通信技术,相对第一代模拟制式移动通信(1G)和第二代GSM、CDMA等数字移动通信(2G) ,第三代移动通信一般地讲,是指将无线通信与国际互联网等多媒体通信结合的新一代移动通信系统。在中国本土通信市场上, 3G作为下一代商用的移动通信技术越来越近。3G对原有的固网运营商和移动运营商的未来发展的重要性以及对现实业务的冲击,都让运营商不得不高度重视3G市场,并投入大量的精力研究自身的3G发展策略。本文从目前的固网运营商及移动运营商各自的优势,对3G业务、用户市场的粗浅分析中,力求得出固网运营商可能的3G发展策略。 相似文献

This paper investigates the relationships between stock returns, changes in production, and changes in interest rates in three European countries: France, Germany, and the United Kingdom. The results obtained using annual data are much more conclusive than those obtained using quarterly data. Stock returns are affected by current changes in interest rates and by future changes in production. The dependence on changes in interest rates seems to be higher than on changes in production. Furthermore, the influence of future changes in production on stock returns diminishes substantially when contemporaneous changes in interest rates are taken into account. With reference to these points, the European markets behave in a similar fashion, but are in sharp contrast with the U.S. market.I am very grateful to Kay Davidson, Patric Hendershott and two anonymous referees for useful comments and suggestions. I am solely responsible for all remaining errors. 相似文献

Incorporating Collateral Value Uncertainty in Loss Given Default Estimates and Loan-to-value Ratios 总被引:11,自引:0,他引:11
We present a model of risky debt in which collateral value is correlated with the possibility of default. The model is then used to study the expected loss given default, primarily as a function of collateral. The results obtained could prove useful for estimating losses given default in many popular models of credit risk which assume them constant. We also examine the problem of determining sufficient collateral to secure a loan to a desired extent. In addition to bank practitioners, regulators might find our analysis useful in reviewing banks’ lending standards relative to current collateral values. In particular, the current proposals for The New (Basel) Capital Accord involve options for the use of banks’ own loss given default estimates which might benefit from the analysis in this paper. 相似文献

Competition For Order Flow, Market Quality, And Price Discovery In The Nasdaq 100 Index Tracking Stock 总被引:1,自引:0,他引:1
We investigate competition for order flow, market quality, and price discovery in the Nasdaq 100 Index Tracking Stock (QQQ). The QQQ, an AMEX‐listed, exchange‐traded fund, is the most actively traded security in the U.S. equities market. On July 31, 2001, the NYSE began trading the QQQ, marking the first time it traded securities of companies it does not list. The greatest volume of trading takes place on electronic communication networks (ECNs), following by trading on the AMEX and the NYSE. Most of the block trades are executed on the AMEX, where the bid‐ask spreads are narrower. We find that ECNs contribute the most to the price‐discovery process. The spreads on all trading platforms have decreased and market quality and price discovery have improved since QQQ shares have traded on the NYSE. 相似文献

This paper uses a probabilistic change-of-numeraire technique to compute closed-form prices of European options to exchange
one asset against another when the relative price of the underlying assets follows a diffusion process with natural boundaries
and a quadratic diffusion coefficient. The paper shows in particular how to interpret the option price formula in terms of
exercise probabilities which are calculated under the martingale measures associated with two specific numeraire portfolios.
An application to the pricing of bond options and certain interest rate derivatives illustrates the main results. 相似文献

We show, using the modified rescaled range statistic, that none of the return series of indices of five European countries, the United States and Japan exhibits long term dependence. This statistic — introduced by Lo (1991) — correct Hurst's (1951) ‘classical’ rescaled range statistic for short term dependence. We also report the classical rescaled range statistic after adjusting the series for short term dependence. This procedure shows, for cases where the results of the modified rescaled range statistic are mixed, that no long term dependence can be found. Simulations indicate reasonable power of this adjustment procedure. Furthermore, we find that estimates of the Hurst exponent, a related measure of long term dependence, are also biased by short term dependence. Simulations show that this measure — that has recently attracted growing interest — cannot distinguish between models with or without long term dependence. 相似文献

In this keynote speech, I ask the question: Does the cost of capital differ for firms located in different countries? I argue that there are two ways to look at the cost of capital. First, there is the neoclassical perspective, which assumes that there are no agency problems. In integrated markets, the neoclassical cost of capital is the same in every country. Second, there is the agency perspective. Agency costs increase the cost of capital understood as the expected rate of return necessary for an investment to leave the value of the firm unaffected. Adjusting the cost of capital for agency costs, I argue that it differs across countries because of differences in corporate governance. I then provide a comparison of the agency-adjusted cost of capital between Japan and the US. 相似文献

Contingent claims separate revenue and cost into two different time periods. Revenue comes in the initial origination process, while the cost comes upon completion of the contract in the event of default. With banks increasing contingent claims in recent years, a higher taxable income leads to a shift in a bank's balance sheet toward tax-free income and tax-shielding liabilities. This provides a valuable case-study of corporate finance theories of tax management. This paper builds a model to illustrate the income features of contingent claims. Call Reports from 1990-1996 are examined, and show significant evidence of increases in leverage associated with contingent claims. 相似文献

We survey 309 sample firms exhibiting behavior consistent with a residual dividend policy and their matched counterparts to learn how they set their dividend policies. The findings reveal that the sample firms are more likely than their counterparts to maintain a long-term dividend payout ratio, use long-run earnings forecasts in setting the dividend, and be unconcerned about the cost of raising external funds. Yet, firms behaving as though they follow a residual dividend policy generally do not profess to follow the policy. At best, the sample firms follow a “modified” residual policy in which they carefully manage their payout ratio and dividend trend. Although it may not be an explicit goal of such a dividend policy, consistently low free cash flow typically results. 相似文献
