    • Children's Learning Gap in Cambodia during the COVID-19 Pandemic: The Effect of Targeted Cash Transfer
      Mingyeong Park, Hyelim Son


         This paper examines the impact of a cash transfer program to poor households during a COVID-19 outbreak on engagement in children¡¯s learning activities in Cambodia. The Cambodian government introduced the IDPoor program to better define target groups to alleviate poverty in 2006. During the COVID-19 pandemic, the government launched a cash relief program mainly benefiting the IDPoor households. Using the High Frequency Phone Survey, we find that receiving cash transfers mitigates the negative impact of poverty on the education opportunities of children in poor households during the pandemic. Receiving cash relief is positively associated with children in poor households engaging more in education activities, particularly using mobile apps and also with the likelihood that the children contact their teachers through the medium of telephone.

    • The Study on Korean Service Firm¡¯s Management Practices
      Hyelin Choi


         As firm¡¯s management and organizational practices are recognized as one of the important determinants of productivity and firm performance, the survey on the management practices are conducted in several countries. This study uses the survey on the innovation and organizational practices for Korean services firms and generates management score. The management scores are generally low in the service sector, in particular regarding targets among monitoring, targets, and incentives. In terms of characteristics of firms, the larger, older, and more innovative firms and foreign-owned and multinational firms show higher management scores. The simple regression analysis supports that higher management scores are positively associated with higher firm performance.

    • Forecasting Crude Oil Prices with Google Trends Data Based on Machine Learning Methods
      Seonmi Kim, Dooyeon Cho


         Forecasting crude oil prices is an important issue, especially for Korea which is the importer of crude oil, since fluctuations in crude oil prices may have a negative effect on the economy. This study investigates some factors that may cause fluctuations in crude oil prices with macro variables as well as Google Trends Data. By employing data on oil demand and supply mainly used in forecasting models for WTI crude oil prices and trends on keywords highly searched during a period of a decline in oil prices, it analyzes whether it can improve forecasting power. We find that including Google Trends Data, besides data on oil demand and supply, can improve predictive ability over the sample period January 2004 to December 2020. To compare predictability in various models, we employ Adaptive LASSO, Ridge Regression, Random Forest, and LSTM. The results suggest that the LSTM model outperforms other models when both structured data and Google Trends Data are jointly used.
