Exchange rate pass-through to domestic producer prices: Evidence from Korean firm-level pricing survey

This note studies exchange rate pass-through to the prices of domestically produced goods, exploring the firm-level pricing survey conducted by the Bank of Korea. The data reveal the imported inputs channel of, as well as nonlinear and asymmetric, exchange rate-pass-through.     

原产国和消费者民族中心主义对组织购买者产品评价的影响

原产国和消费者民族中心主义是全球化营销研究领域的热点问题，但是二者对组织购买者产品评价的影响研究相对较少。本研究以中国组织购买者为被访者，采用结构化问卷对其进行调查。通过多元方差分析和T检验发现，无论是基本生产设备还是辅助生产设备，组织购买者对其评价显著地受到原产国效应影响，尤其是受设计国信息的影响；无论是对本国产品还是文化相似国产品的评价，组织购买者并未受到消费者民族中心主义的影响。另外，本研究还发现，原产国效应不受组织特征的干扰。     

The framework for factors affecting technology transfer for suppliers and buyers of technology in Korea

To gain an ongoing competitive advantage over other firms, a firm must acquire new technology to differentiate itself from others. This paper explores the technology transfer of technology for information technology equipment and establishes a comprehensive framework for the factors which affect on-time completion of technology transfer for suppliers and buyers according to technology transfer agreements. The technology transfer process is divided into the categorical stages that take place. Then, experts’ opinions are analysed through analytic hierarchy process to determine the influential factors affecting on-time completion of technology transfer. The results of this study should provide a basis for firms to evaluate on-time completion of technology transfer and a reference for the technology transfer process for both suppliers and buyers.     

The role of observed and unobserved heterogeneity in the duration of unemployment

This paper studies the degree to which observable and unobservable worker characteristics account for the variation in the aggregate duration of unemployment. I model the distribution of unobserved worker heterogeneity as time varying to capture the interaction of latent attributes with changes in labor-market conditions. Unobserved heterogeneity is the main explanation for the duration dependence of unemployment hazards. Both cyclical and low-frequency variations in the mean duration of unemployment are mainly driven by one subgroup: workers who, for unobserved reasons, stay unemployed for a long time. In contrast, changes in the composition of observable characteristics of workers have negligible effects.     

Attitudes toward risk and self-employment of young workers

A high degree of risk tolerance is often regarded as one of the fundamental characteristics of entrepreneurs. Using multiple responses on risky income gambles in the 1979 National Longitudinal Survey of Youth (NLSY79), I investigate the effect of individual risk tolerance on the probability of entry into self-employment. I construct a measure of individual level of risk tolerance that is corrected for reporting error and that varies with age and other covariates that potentially affect self-employment decision. I find that risk tolerance is an important determinant of the decision to enter self-employment. However, I find that the estimated effect of risk tolerance on the probability of entering self-employment is dramatically understated if measurement error is not taken into account. In addition, I find that that accounting for the correlation between risk tolerance and other covariates is important to correctly assess the effects of the other determinants of self-employment while it has a trivial effect on the estimated marginal effect of risk tolerance.     

The employment dynamics of less‐educated men in the United States: The role of self‐employment

Using data from the 1979 National Longitudinal Survey of Youth, I construct a sample of working‐age males and examine the employment dynamics with a particular focus on the role of self‐employment for less‐educated men in the US. I find that men responding they had at some point been self‐employed tend to spend less time in non‐employment than other less‐educated men. The results from the dynamic multinomial logit model reveal positive aspects of self‐employment by indicating that less‐educated men who were self‐employed in the previous year were less likely to be non‐employed in the future as compared to those who were paid workers in the previous year.     

The choice of a monetary instrument in a small open economy: The case of Korea

Using a small macroeconometric model of Korea, this paper evaluates the correct choice of a monetary instrument (either the money stock or the interest rate), the optimal multiperiod policy, and the value of current information on some monetary varialbles.     

Efficiency characterizations in different DEA models

Relations of efficiency and non-efficiency for the same sets of DMUs (Decision Making Units) are developed for the Charnes, Cooper and Rhodes (CCR) and Barker, Charnes, Cooper (BCC) ratio models, as well as DEA Additive and Multiplicative Models. Surprisingly, additively efficient DMUs are not necessarily multiplicatively efficient. A geometric “stretching” phenomenon is identified for the latter case.     

Some statistical and DEA evaluations of relative efficiencies of public and private institutions of higher learning

This paper uses the Charnes, Cooper and Rhodes (CCR) ratio form of Data Envelopment Analysis (DEA) (1) to examine how DEA can be utilized in analyzing different aspects of production behavior of institutions of higher learning (IHLs) as an alternative to more traditional approaches such as econometric-regression models, and (2) to compare “specifically” relative efficiencies of public and private doctoral-granting universities in the U.S. and to analyze technical and scale efficiencies of those universities. The separation of doctoral-granting universities into universities with and without medical colleges represents a departure from preceding studies. This division proved very important in uncovering substantial differences in behavior between the two groups even when using the “statistical averaging” approaches that were customary in previous studies. For both groups, public universities proved more efficient than private universities when managerial and program inefficiencies are present in the data. When managerial inefficiencies are disentangled from the data and medical schools are not present, private universities have more efficient programs. However, their managers are less efficient users of program opportunities than are managers in public universities. Another portion of the current study dealt with returns-to-scale possibilities. These differed markedly (even on average) between IHLs with and without medical schools. Moreover, analyses by DEA showed marked ranges of variation for returns-to-scale possibilities for individual IHLs within each group. These possibilities have generally been concealed by the statistical averaging utilized in previous econometric studies. Further, their identification is beyond the ability of the usual types of one-at-a-time ratio and trend analyses.
