The paper aims to measure transaction costs and its effects on labor market participation and on wage earnings. The observed differences between buying and selling prices of rice across households are used to calculate transaction costs indices for villages which are incorporated into the standard labor market participation and Mincer wage equations. The estimates indicate that transaction cost...

Agricultural trade policies in Korea and Japan drew much attention during the negotiations leading to the Uruguay Round Agreements on Agriculture (URAA). Before the UR the countries and others had been using non-tariff barriers and many other intervention measures in agriculture. Korea and Japan argued vigorously for maintaining their farm import barriers and subsidies. Throughout the negotiati...

Appearance and milling quality are two crucial properties of rice grains affecting its market acceptability. Understanding the genetic base of rice grain quality could considerably improve the high quality breeding. Here, we carried out an association analysis to identify QTL affecting nine rice grain appearance and milling quality traits using a diverse panel of 258 accessions selected from 3K...

A high performance liquid chromatographic method was developed for determination of aflatoxin B1 (AFB1) in foods using a monolithic column with sample clean up on an immunoaffinity column. The method was validated for analysis of AFB1 in rice, bread, puffed corn snack, wheat flour and peanut samples. The average recoveries for AFB1 in different foods ranged from 94.4 to 102.5% with the coeffici...

A survey of the levels of some essential and non-essential trace elements in different types of rice available on the Swedish retail market was carried out in 2001-03. The types of rice included long and short grain, brown, white, and parboiled white. The mean levels found were: chromium (Cr) = 0.008 mg kg(-1), copper (Cu) = 1.9 mg kg(-1), iron (Fe) = 4.7 mg kg(-1), manganese (Mn) = 16 mg kg(-1...

Nutritional and dietary interventions and the introduction of novel food products and ingredients require a thorough understanding of the drivers of food choice, which are embedded in local context and culture. We developed a framework of "gastronomic systems research" (GSR) to understand culture-specific consumer food choice, and contextualise it to a target population of urban, middle- to hig...

Job Market Signaling and Employer Learning This paper extends the job market signaling model of Spence (1973) by allowing firms to learn the ability of their employees over time. Contrary to the model without employer learning, we find that the Intuitive Criterion does not always select a unique separating equilibrium. When the Intuitive Criterion bites and information is purely asymmetric, the...

This study extends from Liu and Mei (1992) by further investigation of assets, real estate related securities, which includes both equity and mortgage real estate investment trusts (REITs), the stocks of builderand owner-companies, and mortgagebacked securities (MBSs). There are five major findings. First, expected excess returns of real estate related securities are more predictable than the e...
