We examine asymmetry in the loss functions of South Korean consumers' and the Bank of Korea's (BOK) inflation forecasts, and test the rationality of these forecasts under the assumption of a possible asymmetric loss function. Under an asymmetric loss function, we find evidence of asymmetry and support for rationality. We also examine whether the BOK's forecasts incorporate respective forecasts and consensus forecasts efficiently. They broadly use available information efficiently, and their results are robust to inflation‐targeting measures and the recent global financial crisis. However, our results suggest that the information efficiency of the BOK's forecasts for consumers was affected during the period 2007–2008. 相似文献

This article investigates the effects of corruption on the performance of the manufacturing sector at the state level in India. We employ conviction rates of corruption-related cases as an instrument for the extent of corruption, address the underreporting problem, and examine the impact of corruption on the gross value added per worker, total factor productivity, and capital-labor ratio of three-digit manufacturing industries in each state. Our estimation results show that corruption reduces gross value added per worker and total factor productivity. Furthermore, we show that the adverse effects of corruption are more salient in industries with smaller average firm size. 相似文献

We consider the multistage hybrid flowshop scheduling problem, in which each stage consists of parallel identical machines. The problem is to determine a schedule that minimizes the makespan for a given set of jobs over a finite planning horizon. Since this problem class is NP-hard in the strong sense, there seems to be no escape from appealing to heuristic procedures to achieve near-optimal solutions to real life problems. First, a series of new global lower bounds to be used to estimate the minimum makespan are derived. Then, two new metaheuristic algorithms first sequence and then allocate jobs to machines based on a particular partition of the shop. The optimization procedure is based on simulated annealing and the variable-depth search. Computational experiments show the efficiency of the proposed procedures. 相似文献

This paper tries to develop a probabilistic model of location choice by many types of individuals who interact among themselves in the presence of neighborhood effects. Equilibrium is defined as an allocation of individuals among locations such that for every type of individuals the selection probability for each location is equal to the proportion of individuals actually choosing the location in question. The existence of equilibrium is proved under usual continuity assumptions. The equilibrium is shown to be unique and stable in the presence of neighborhood effects, if the degree of externality is sufficiently small. 相似文献

In this paper we examine interregional income inequalities in Indonesia from 1975 to 1992, Williamson's weighted coefficient of variation is used to measure interregional income inequality. We also perform a sectoral decomposition analysis to investigate the extent to which industrial sectors contribute to the overall weighted coefficient of variation. One major finding is that, although interregional income inequality remained fairly stable in non-mining GDP during the study period, it has undergone a significant change in structure. The contribution of the tertiary sector to inequality, though still dominant, has gradually declined. The secondary sector, meanwhile, is playing an increasingly important role, reflecting its growing share of GDP. Inequality is much smaller in consumption expenditure than in non-mining GDP. Its consistently high levels in fixed capital formation reflect the uneven distribution of investments over space in Indonesia. 相似文献

This paper considers a two-dimensional rectangular city with a grid road system, including a square city as a special case, and then derives a simple equilibrium traffic pattern in the case of constant road width. We maintain that while land-use decisions using market rents would lead to overallocation of land to transportation in our square city as in the Solow Vickrey long narrow city, the tendency towards excessive road-building is stronger near the city boundaries than at the city center in our two-dimensional case, contrary to the conclusion drawn from the Solow Vickrey model. 相似文献

Assuming that two‐step monotone missing data is drawn from a multivariate normal population, this paper derives the Bartlett‐type correction to the likelihood ratio test for missing completely at random (MCAR), which plays an important role in the statistical analysis of incomplete datasets. The advantages of our approach are confirmed in Monte Carlo simulations. Our correction drastically improved the accuracy of the type I error in Little's (1988, Journal of the American Statistical Association, 83 , 1198–1202) test for MCAR and performed well even on moderate sample sizes. 相似文献

In this paper, we consider the problems associated with the development and management of an educational program for manufacturing managers in leadership roles who are making contributions towards the creation of customer delight as well as customer satisfaction using manufacturing technology. The basic concept combines an intelligent knowledge-based approach with the kaizen activity program within the framework of value creation and comparative advantage models based on a network referred to as Academia, Business, Consultancy, and Government (ABC-G). This educational program, which reflects the characteristics of manufacturing technologies and practices in the Hokuriku District of Japan, was developed in 2005–2006 and the trial education was developed in 2005 and 2006, and a trial run of this program was conducted in 2006 and 2007 in close collaboration with local manufacturing companies and their employees. The results are informative of the effects of educating manufacturing managers in Japan and the problems that will have to be overcome for the continuous improvement of the program. 相似文献
