This paper presents the utilization rate of capital equipment in the S. Korean manufacturing industry during 1962–1971. The aggregate utilization rate is shown to have increased at an annual rate of about 8%. The level of utilization in S. Korea is found to be generally lower even in 1971 than in the U.S. in 1962, both at the aggregate and sectoral levels. The rise in the utilization rate is shown to have contributed nearly as much as investment has in the growth of manufacturing output. The influence of the residual component declines from 36% to 8% of the recorded growth of output when the increase in the utilization rate is properly allowed for. 相似文献

Customers' perceptions of price differ in the online environment due to the presence of price comparison sites. The purpose of this study is to examine how price comparison sites affect price and value perceptions of online shoppers across different product types and price consciousness levels of online shoppers. The results of the study indicate that the price information provided by an online price comparison site influences online shoppers' perceptions of internal reference prices. However, the influence of a price comparison site on value perception differs according to product type. As evidenced by the significant interaction effect between product type and price comparison site information, the presence of price comparison sites increases both transaction and acquisition value perceptions for the non-look-and-feel product category (e.g., notebook computers), but not for the look-and-feel product category (e.g., jeans). Contrary to the expectation, online shoppers' price consciousness influences their price and value perceptions independently of price comparison site information. 相似文献

Rice is the staple food of nearly half of the population of the world, most of whom live in developing countries. Ensuring a domestic supply of rice from outside sources is difficult for developing countries as less than 5% of the total world’s production is available for international trade. Hence, in order to ensure domestic food security, e.g., food availability and access, governments provide subsidies in agriculture. In many occasions, public money used for the subsidy goes toward promoting undesirable crops like tobacco. Although the strategic interaction between governments and manufacturers is critical, it has not been studied in the literature. This study fills this gap by considering a game between a government (of a developing country) and a tobacco manufacturer in which the government decides on a mix of subsidies and the tobacco manufacturer decides on declaring a purchasing price of tobacco. We provide a numerical study to show that controlling the output harvest price is more effective in reaching the desired end result for both the government and the tobacco manufacturer. A subsidy in fertilizer results in the measurable increase in the government spending but does not have significant effect in reaching the production target. The fertilizer subsidy should be provided only when the output price is too high to be affordable for the population. 相似文献

Financial and operational decisions in the electricity sector: Contract portfolio optimization with the conditional value-at-risk criterion 总被引:1,自引:0,他引:1

The restructuring of electricity markets around the world have caused increased volatility and uncertainty of the price power. As a result, providers of power now face increased uncertainty and risk in the operational and financial decisions related to procurement. Providers must seek optimal ways to deliver the required volume of power to retailers and end users while managing risk. We consider a mixed-integer programming model for a power providing agent that jointly considers the problem of selecting custom electricity contracts and finding the optimal procurement strategy of meeting contract obligations under spot price uncertainty. A two-stage stochastic integer programming (SIP) model with a conditional value-at-risk (CVaR) constraint to incorporate risk aversion is developed. Computational results are presented that demonstrates the CVaR approach and the results are compared with a corresponding expected cost minimization approach. The SIP model with CVaR will allow acceptance of contracts at lower prices compared to an approach based on a corresponding risk-neutral model as a hedge against uncertainty and mis-specified arbitrage. 相似文献

I study an incentive problem that has been largely ignored in the agency literature: incentives for repeated (human capital) investment. The optimal contract is very simple but still provides rich implications for incentive and wage structures in large organizations. The empirical evidence is presented using personnel records of health insurance claim processors in a large U.S. insurance company. These processors are white‐collar, nonmanagerial, female, service industry workers—a rapidly growing but rarely studied labor group. The empirical findings are consistent with the main features of the optimal contract. 相似文献

A sample of Iowa farm couples is used to evaluate whether off‐farm labor supply decisions respond to permanent and transitory components of farm income. Off‐farm labor supply of both spouses declines in response to increases in permanent farm income. Farm wives also reduce off‐farm labor supply in response to positive transitory farm income shocks. Consequently, one mechanism farm households use to smooth their goods consumption when facing fluctuating farm income is to modify their consumption of leisure. Ability to smooth goods consumption does not imply the absence of liquidity constraints among farm households unless leisure consumption is also smoothed. 相似文献

This paper investigates the impacts of oil price shocks and US economic uncertainty on emerging equity markets within a structural VAR model. I find that both precautionary oil demand and US economic uncertainty shocks have significant negative effects on emerging stock returns, whereas aggregate demand shocks cause a sustained rise of the returns. In particular, the direct effects of oil shocks on emerging stock returns are amplified by the endogenous response of US economic uncertainty. Variance decomposition analysis shows that oil market fundamentals and US economic uncertainty are an important determinant of emerging equity returns, accounting for 35% and 24% of their long-term variations, respectively. The heterogeneous impacts of structural shocks on individual emerging markets, however, suggest that a well-diversified portfolio can be obtainable. 相似文献

This paper empirically estimates antitrust damage based on the rich information on cost factors in the bid-rigged Texas school milk market. Empirical results demonstrate that damage estimate by antitrust agency is a significantly underestimated amount of the true damage. This understatement of true harm inevitably includes implementation biases in the antitrust system. [K21, L13, L40] 相似文献

Haltiwanger and Harrington (1991) reveal that, while the gain from deviating from a collusive agreement in an oligopolistic industry is greatest during booms, it is most difficult to collude during recessions since forgone profits inflicted on defection are relatively low in recessions. Their numerical simulations show that firms price more countercyclically during recessions than during booms to deter relatively greater incentive to defect in recession. This paper tests for a potential asymmetry in the response of margins to the level of demand across booms and slumps, using panel data covering 180 U.S. four-digit level SIC manufacturing industries over the 1963-1987 period. The principal findings accept this theoretical prediction. [L1, L6] 相似文献
