This article investigates economic factors and non‐economic factors of individual attitudes toward free‐trade agreements with different countries. Based on the Stolper–Samuelson theorem, highly skilled workers in Taiwan should be more supportive of free trade with China and less supportive of free trade with the United States than should unskilled workers in Taiwan. Using survey data from Taiwan, we find that highly educated people in Taiwan are more supportive of free trade with both the United States and China, and the effects of education are much stronger with respect to free trade with China. We also find that individual risk attitudes, national identity, and ethnicity play important roles in explaining trade preferences. 相似文献

This study has developed a translog cost function for the Kaohsiung City Bus (KCB) to analyse its cost structure and economic characteristics, based on monthly data over the time period from January 1996 to December 2000. The empirical results reveal that economies of density in the provision of bus services in Kaohsiung do prevail. The estimated marginal cost, which is less than the average cost but greater than the current bus fare, indicates that the subsidy is necessary. Due to the existence of returns to density (RTD), the KCB could obtain cost-saving benefits by extending its output scale. The KCB production technology is also not neutral. The effects of technological change on the KCB costs suggest that over the period 1996–2000 technological progress did lead to cost saving; the pure productivity growth rate increased from 0.45% in 1998 to 3% in 2000. 相似文献

Evidence of Stock Returns and Abnormal Trading Volume: A Threshold Quantile Regression Approach 下载免费PDF全文
This paper presents a capital asset pricing model‐based threshold quantile regression model with a generalized autoregressive conditional heteroscedastic specification to examine relations between excess stock returns and “abnormal trading volume”. We employ an adaptive Bayesian Markov chain Monte Carlo method with asymmetric Laplace distribution to study six daily Dow Jones Industrial stocks. The proposed model captures asymmetric risk through market beta and volume coefficients, which change discretely between regimes. Moreover, they are driven by market information and various quantile levels. This study finds that abnormal volume has significantly negative effects on excess stock returns under low quantile levels; however, there are significantly positive effects under high quantile levels. The evidence indicates that each market beta varies with different quantile levels, capturing different states of market conditions. 相似文献

This paper uses a reduced‐form approach to derive a closed‐form pricing formula for defaultable bonds. The authors specify the default hazard rate as an affine function of multiple variables which follow the Lévy jump‐diffusion processes. Because such specification allows greater flexibility in the generation of a valid probability of default, their pricing model should be more accurate than the valuation models in traditional studies, which ignore the jump effects. This paper also proposes a new method for estimating the parameters in a Lévy Jump‐diffusion process. The real data from the Taiwanese bond market are used to illustrate how their model can be applied in practical situations. The authors compare the pricing results for the influential variables with no jump effects, with jump magnitudes following the normal distribution, and with jump magnitudes following the gamma distribution. The results reveal that the predictive ability is the best for the model with the jump components. The valuation model shown in this paper should help portfolio managers more accurately price defaultable bonds and more effectively hedge their portfolio holdings. 相似文献

In this paper, we try to investigate how the debt and real GDP per capita relationship varies with indebtedness levels and other country characteristics in a balanced panel of 21 developing Latin American and Caribbean countries over the period 1992–2006. The empirical results indicate that there exist two threshold values of 32.88% and 55.89%. The latter is lower than the Maastricht criterion and Stability and Growth Pact of a total external Debt per GDP ratio at 60% in the OECD countries. Both thresholds divide our panel into three regimes. In the middle (stimulus) regime, the Debt per GDP ratio has a positive impact on real GDP per capita, which is consistent with the stimulus view (Eisner, 1984). However, the impact becomes negative and consistent with the crowding-out view (Friedman, 1977, 1985) in the left and right (crowding-out) regimes. Based on our findings, we find no supportive evidence for Ricardian view (Barro, 1989). Therefore, our empirical results have important implications for fiscal policymakers in these Latin American and Caribbean countries. 相似文献

This article proposes a new approach to evaluate volatility contagion in financial markets. A time-varying logarithmic conditional autoregressive range model with the lognormal distribution (TVLCARR) is proposed to capture the possible smooth transition in the range process. Additionally, a smooth transition copula function is employed to detect the volatility contagion between financial markets. The approach proposed is applied to the stock markets of the G7 countries to investigate the volatility contagion due to the subprime mortgage crisis. Empirical evidence shows that volatility is contagious from the US market to several markets examined. 相似文献

This paper addresses the multiobjective flexible job shop scheduling problem (MOFJSP) regarding minimizing the makespan, total workload, and maximum workload. The problem is solved in a Pareto manner, whose goal is to seek for the set of Pareto optimal solutions. We propose a multiobjective evolutionary algorithm, which utilizes effective genetic operators and maintains population diversity carefully. A main feature of the proposed algorithm is its simplicity—it needs only two parameters. Performance of our algorithm is compared with seven state-of-the-art algorithms on fifteen popular benchmark instances. Only our algorithm can find 70% or more non-dominated solutions for every instance. 相似文献

This study analyzes the effect of premium rates on banks’ incentives to join a deposit insurance scheme and their incentives
to invest in risky projects under a voluntary deposit insurance scheme. We find that in order to maximize social welfare,
the insurance agency must either set the premium rate to be low so as to attract all banks to join the insurance scheme, or
not to have the deposit insurance at all. However, the low premium rate in the voluntary scheme does not balance the budget
of the deposit insurance. We also show that in the compulsory deposit insurance scheme, however, it is possible to impose
an optimal premium rate that can balance the insurance agency’s budget and achieve the highest social welfare. The results
also present the dominance of the compulsory scheme over the voluntary scheme in terms of maximizing social welfare and balancing
the budget.

The recent advent of the interest rate futures markets has greatly enriched the hedging opportunities of market participants faced with undesired interest rate risk. The variety of futures contracts presently spans a number of instruments with different risk, maturity, and coupon characteristics. This paper modifies the concept of duration and extends the duration hedging approach to cases where futures contracts are used as the hedging instrument. The derived hedge ratios take into account differences in coupon, maturity, and risk for three different regimes. Usage of these hedge ratios should lead to more efficient hedging of interest rate risk. 相似文献
