Between 2006 and 2011, Nicaragua shipped an average of US$9.4 million per year of smallholder-produced fresh taro (Colocasia esculenta) to the USA; however, by 2016, the US market for Nicaraguan taro had effectively collapsed. The purpose of this paper is to analyze the short-lived taro boom from the perspective of complex adaptive systems, showing how shocks, interactions between value chain actors, and lack of adaptive capacity among chain actors together contributed to the collapse of the chain.

Primary data were collected from businesses and smallholders in 2010 and 2016 to understand the actors involved, their business relations, and the benefits and setbacks they experienced along the way.

The results show the capacity of better-off smallholders to engage in a demanding market, but also the struggles faced by more vulnerable smallholders to build new production systems and respond to internal and external shocks. Local businesses were generally unprepared for the uncertainties inherent in fresh horticultural trade or for engagement with distant buyers.

Existing guides and tools for designing value chain interventions will benefit from greater attention to the circumstances of local actors and the challenges of building productive inter-business relations under higher levels of risk and uncertainty.

This case serves as a wake-up call for practitioners, donors, researchers, and the private sector on how to identify market opportunities and the design of more robust strategies to respond to them.

Recently the route connecting the trans-Korean railway and the trans-Siberian railway has become of particular interest for many academics and policy-makers in East Asian countries. The extensive review of previous studies, however, reveals that literature on the subject is lacking solid analytical framework. Most studies are one-sided, focusing on the political aspects of the issue or paying little attention to the economic aspects of the problem.

This study intends to develop an analytical framework through which the most efficient route among four major alternative routes connecting the trans-Korean and trans-Siberian railways can be identified. It attempts to assign priorities to the four alternative routes according to their level of economic efficiency.

This study utilizes a simple cost-benefit analysis in evaluating the four routes. Cost side, transportation time, effectiveness of customs procedures, and gauge difference are selected as the main economic factors. The volume of cargo, industrial production in adjacent regions, access to natural resources, and market size and foreign investment climate are used to evaluate the benefits of the routes.

The study concludes that Route 3, which connects ‘Busan - Seoul (South Korea) –Pyongyang -Sinuiju (North Korea) –Shenyang –Beijing - Erenhot (China) –Ulaanbaatar (Mongolia) –Ulan-Ude - Moscow (Russia)’ is the most efficient route.

In a supply-constrained region like Asia, promoting exports has always been a challenge particularly at a time when Asia’s trade has been severely affected by lack of external demand. This paper argues that price barriers have taken a new shape during the global financial crisis period which may generate differential impacts on trade flows as we proceed toward recovery. The size and shape of price barriers would be higher if NTBs, applied by the countries during the crisis period, were counted. One of the conclusions of this paper is that ‘price’ barrier is still more important than ‘non-price’ barrier in enhancing Asia’s trade and integration. The higher the price barrier between countries in a pair, the less they trade. In other words, a 10 percent increase in the ad-valorem price (transport and tariff) lowered trade by 6 percent. Tariff and transport costs, each considered separately, also influence the trade flow in the same direction, to more or less the same extent. There are indications of huge domestic infrastructure bottlenecks in countries in Asia. Based on direct and indirect evidence related to trade barriers, this paper concludes that complementary trade policies focusing on price and non-price barriers have immense importance in enhancing international trade and integration in the post-crisis period.

One of the important goals of trade facilitation is to lower the costs of trade that serve as a barrier to the developing countries from enjoying the benefits of increased trade and becoming integrated into global supply chains that account for nearly 60 percent of global trade today. The high trade costs that are plaguing most developing countries is mainly incurred from the lack of adequate trade-related infrastructure and low quality of institutions that hinder the efficient flow of goods across and within borders. Therefore, the trade facilitation rules that are contained in FTAs among bilateral trading partners are inevitably aimed at deepening their participation in the global value chain network. However, an observation of the FTAs concluded by Korea and the trade facilitation rules contained therein shows that the current trade facilitation rules in bilateral FTAs may be of little practical use for countries that lack the capacity to be involved in the international production activities in the first place. From the development perspective, the current WTO negotiations on trade facilitation which take full account of the special and differential treatment needs of the less developed country members appear more likely to contribute to providing the trading environment that is free from the barriers to trade that have inhibited the less developed countries from integration into the global supply chains and the benefits thereof.

To examine the perspective of third-level university students in the context of the value proposition of construction apprenticeships in Ireland.

The research uses a qualitative method, conducting semi-structured interviews with 20 third-level university students enrolled on a Bachelor of Science (Honours) degree program in Construction Management in Ireland.

The results highlight six themes. These include that society appears to be directly and/or indirectly steering students towards university. This is driven by what appears to be a prevailing stigma in that apprenticeships are not seen as an achievement by society. Also, apprenticeships are seen as a limited career choice, while also being one which appears to repel female entrants.

If the shortage of new skilled workers entering the construction industry continues, construction organisations will not have the necessary resources to tender for, and subsequently, complete new work.

The perception of what could have been seen as potential new apprenticeship entrants, but ultimately chose university, is worth examining further with a view to industry addressing the shortcomings identified. This therefore can provide an opportunity to stem the tide of reducing apprenticeship numbers, while also providing a viable alternative to university for those who wish to pursue alternative routes of entering the sector.

The paper uniquely focuses on the third-level university student's perspectives and what influenced their decision to pursue third-level university education over that of an apprenticeship within the built environment; an area which has yet to be investigated.

A core employment market based on modem information and communications technology (ICT) and human resources (HR) management can fundamentally overcome the shortcomings of a traditional employment market, in which the problems of an imbalance in the relationship between employers and employees are antagonistically alleviated by independent trade unions and other similar means. Core employment means the portion of total employment closely related to modem entrepreneurial innovation - the employment of directly or indirectly aiding in conducting, promoting, protecting and expanding innovation with entrepreneurship. The severe industrial conflicts existing currently in Korea and China can probably be resolved by economic and social measures other than confrontational trade unions, as long as the efforts are made in an expansion of core employment by the government, enterprises and individuals.

For policymakers and participants of financial markets, predictions of trading volumes of financial indices are important issues. This study aims to address such a prediction problem based on the CSI300 nearby futures by using high-frequency data recorded each minute from the launch date of the futures to roughly two years after constituent stocks of the futures all becoming shortable, a time period witnessing significantly increased trading activities.

In order to answer questions as follows, this study adopts the neural network for modeling the irregular trading volume series of the CSI300 nearby futures: are the research able to utilize the lags of the trading volume series to make predictions; if this is the case, how far can the predictions go and how accurate can the predictions be; can this research use predictive information from trading volumes of the CSI300 spot and first distant futures for improving prediction accuracy and what is the corresponding magnitude; how sophisticated is the model; and how robust are its predictions?

The results of this study show that a simple neural network model could be constructed with 10 hidden neurons to robustly predict the trading volume of the CSI300 nearby futures using 1–20 min ahead trading volume data. The model leads to the root mean square error of about 955 contracts. Utilizing additional predictive information from trading volumes of the CSI300 spot and first distant futures could further benefit prediction accuracy and the magnitude of improvements is about 1–2%. This benefit is particularly significant when the trading volume of the CSI300 nearby futures is close to be zero. Another benefit, at the cost of the model becoming slightly more sophisticated with more hidden neurons, is that predictions could be generated through 1–30 min ahead trading volume data.

The results of this study could be used for multiple purposes, including designing financial index trading systems and platforms, monitoring systematic financial risks and building financial index price forecasting.

The purpose of this paper is to explore the value that UK trade unions now place on the living wage.

The author is the TUC’s Pay Policy Officer and examines the issue from a practitioner’s perspective.

The living wage now has a well-established place within the hierarchy of pay demands adopted by UK trade unions. This continues a tradition of unions supporting norms and regulations as an adjunct to collective bargaining. However, support had to be achieved through a process of negotiation with the broader UK living wage campaign.

The paper concludes that there are good prospects for the living wage, and thus for the continued trade union support.

The living wage standard is seen as having a strong moral basis, which often helps to win agreement with good employers. This results in a steady stream of workers out of in-work poverty. The credit for such pay increases is often shared between employers and trade unions.

The paper is written by a practitioner with inside knowledge and experience of the entire course of the living wage campaign in the UK and how it has been adopted and integrated by trade unions.
