Middle school is an important period of development for students. Middle schools in China are either separate schools after grade six or incorporated in the same school complex with the elementary school. Students who attend separate elementary and middle schools change schools more often than...

Motivated by the advantage of just-in-time philosophy, zero-inventory is common in many industries, especially the ones that need fast response with a short lifespan. Accordingly, this paper focuses on coordinated production scheduling and distribution operation problems considering DeJong’s...

This paper investigates how to improve prediction accuracy of stock realized volatility using a large set of predictors. Exploiting normalized positive adjusted R-square and significant t statistic of predictor obtained from the in-sample result as weight, we develop two simple and effective...

This paper investigates the production scheduling problems of allocating resources and sequencing jobs in the seru production system (SPS). As a new-type manufacturing mode arising from Japanese production practices, seru production can achieve efficiency, flexibility, and responsiveness...

This study investigates the predictability of a fixed uncertainty index (UI) for realized variances (volatility) in the international stock markets from a high-frequency perspective. We construct a composite UI based on the scaled principal component analysis (s-PCA) method and demonstrate that...

This paper was commissioned by the APEC Working Group on Fisheries to examine the economic impact of eliminating tariffs on fish and fish products in APEC economies. Chapter II provides a qualitative assessment of the impacts of liberalization of fisheries trade drawing on the available data and...

Futures margin setting is important for an exchange policy since it is the balance between the loss and benefit of an exchange. This paper develops a method for setting the margin level for two-commodity portfolios. The bivariate extreme value theory is applied in our estimation to compute the...

We show how non-parametric flexibility can be attained in a structural labour supply model that can be used to analyse all sorts of (non-linear) tax and benefits reforms. The direct utility function is approximated with a series expansion. For given length of the expansion, the model is...

The thesis covers three topics on the labour market and on consumer demand. Chapters two and three focus on the labour market mobility and wage differentials between the formal sector and the informal sector in urban Mexico. Dynamic random effects panel data models are used in the analysis....
