This study examines the effect of transaction costs on the time series behavior of stock returns over a period surrounding the April 1989 changes in tax rates on securities transactions and capital gains in Japan. We find significant decreases in estimates of the first-order autocorrelation in returns for Japanese stocks listed in Japan, but no changes for Japanese stocks dually listed in the United States as American Depository Receipts (ADRs), which were not subject to the tax law change. We also find lower price basis between the ADRs and their underlying Japanese stocks. These results are consistent with the hypothesis that a reduction in transaction costs improves the efficiency of the price discovery process.

Since demand for hospital services is subject to substantial variability, the relationship between uncertain demand, excess capacity, hospital costs and performance should be investigated thoroughly. In this paper a waiting time indicator to proxy hospital standby capacity is incorporated into a multi-product translog cost function for Belgian general care hospitals. The indicator is derived from queuing theory and improves on the conventionally used (inverse of the) occupancy rate. The multi-product stochastic frontier specification allows calculation of cost elasticities and marginal cost of seven hospital departments, as well as the degree of economies of scale and scope and enables identification of differences in efficiency.

We examine the consequences when the public is unsure about the ability of governments to foresee the effects of decisions. Governments with much information should invest either immediately or never. Governments that are not well informed should wait for better information. But since governments want to signal their abilities to solve problems, we observe rash decisions and problems are portrayed as crises. We also show that excessive delay can occur. Delay or rush occur even if there is very little uncertainty about abilities of governments. We discuss three institutional rules to alleviate the rush and delay bias: Limiting expenditures before elections, experimental clauses or money burning.  相似文献

Concerns have arisen over employers' collection and sharing of information about employees, especially employment references. As a result of the dramatic growth in the number of lawsuits brought by employees, many employers have seriously curtailed the information they release concerning current and former employees. However, even the refusal to release information carries a legal risk. Employers who do not obtain information concerning applicants can be liable for negligent hiring, and those who knowingly withhold negative information regarding their former employees may be liable for negligent referral. This paper explores these expanding liabilities and suggests strategies to allow employers to manage the risk of communicating employee references.  相似文献

This paper examines the price discovery process of the nascent gold futures contracts in the Multi Commodity Exchange of India (MCX) over the period 2003 to 2007. The study employs vector error correction models (VECMs) to show that futures prices of both standard and mini contracts lead spot price. We find that mini contracts contribute to over 30% of price discovery in gold futures trade even though they account for only 2% of trading value on the MCX. Our finding reveals that trades initiated in mini contracts are much more informative than what the size of their market share of volume suggests.  相似文献

This study provides recent empirical evidence on the impact of the federal budget deficit on the ex ante real interest rate yield on Moody’s Baa-rated corporate bonds. The study is couched within an open loanable funds model that includes the ex ante real short term real interest rate, the M1 money supply, net international capital inflows, and the unemployment rate. Using quarterly data for the period 1973.1–2007.4, two-stage least squares estimation reveals that the federal budget deficit, expressed as a percent of GDP, exercised a positive and statistically significant impact on the ex ante real interest rate yield on these corporate issues.  相似文献

In an effort to fight inflation or recession, central banks manipulate the money supply. The speed with which a change in money supply could affect price level and the level of production differs from one country to another, depending on rigidities. The main purpose of this paper is to show that the adjustment speed among the mentioned macro variables is higher in countries that are more open. Using the bounds-testing approach, a relatively new approach to cointegration and error-correction modeling, we estimate the speed of adjustment in the money market in 28 developing countries. A simple cross-sectional model is utilized in which the measure of adjustment speed is related to three different measures of openness. Regardless of the measure used, a significant and positive relationship exists between adjustment speed and the measure of openness.  相似文献

This paper examines the relationships amongst volatility, total trading volume (TVOL) and total open interest (TOI) for three Taiwan stock index futures markets as well as the role of the latter two variables in the dynamics of GARCH modeling and forecasting. From both ex-post and ex-ante perspectives, we study this issue by using the VAR model and augmented GARCH-type models, respectively. For the GARCH-type models, we employ both symmetric and asymmetric models augmented with lagged logs in TOI and/or TVOL. We find that whether addition of these two variables helps the basic GARCH models predict future volatility depends upon the sample period examined for all three sets of futures. Nonetheless, the best three models for out-of-sample volatility forecasting in the MSE sense are generally the augmented models for all sub-intervals and all three futures contracts.  相似文献

In the current global corporate climate that surrounds us, firms would do well to encourage the talent and creativity of their employees in order to achieve success. This is achieved, not by giving priority to individual talent, but by optimizing the collective as a whole and the firm’s activity based on team work and joint effort. Heads of organizations might benefit from creating a favorable context for the birth and growth of collective internal cooperation, which is understood to be the collective ability to create and innovate on the part of the team, the firm or the organization. Having contrasted our hypotheses through research on Spanish firms, we have concluded that job satisfaction and commitment to the team are factors that have a direct and positive effect on collective entrepreneurship.  相似文献
