Broadband Demand Analysis for Network Building

An increase of broadband demand is forecasted by transitional methods that consider the effect of this increase through many factors, such as customer requirement diversification, and new service introduction and deployment under competition. Broadband demand forecasting has become important for closing the digital divide, promoting regional developments, and constructing networks economically; therefore, a demand forecast model that considers the mechanisms of market structure is necessary. In this paper, a demand analysis method for broadband access combining macro- and micro-data mining is proposed, and the service choice behaviour of customers is introduced as a customer model not only to express the macro trend of market structure, but also to consider area marketing. The proposed method can estimate the potential demand, determine the point at which broadband demand growth peaks in a specified area, and support a decision for ultra high-speed broadband access facility installation.     

Selecting optimal intermediary channels in emerging markets: The case of Vietnamese toiletries

Abstract

Domestic distribution in Vietnam is characteristic of an emerging market in the beginning stages of modernization, with frequent changes in retail format, a fragmented distribution structure, and ambiguous regulations. This study uses field surveys and comparative analyses of individual enterprises in Vietnam’s toiletry products industry to identify suitable channel strategies for emerging markets in the early stages of distribution modernization. The results indicate that partnership channels are more suitable than hierarchy and market governance channels. Moreover, among the various types of intermediaries, distributors provide a key role in emerging markets where transportation functions are undeveloped. Finally, the study investigates the various methods of partner selection, finding that effectiveness-oriented networks are superior to large-scale efficiency-oriented networks because they have greater channel coverage in modernizing emerging markets. The findings demonstrate the optimal channel structures and partner selection criteria for distributors in emerging markets.     

Impact of hypermarkets on consumption and distribution in rural areas: case study of Ubon Ratchathani in northeastern Thailand

Hypermarkets in East Asian countries have reached a turning point in their life cycle, where local expansion has become essential for further development. Unfortunately, existing studies on retail internationalisation have paid little attention to rural development. To address this gap, this study evaluates the impacts of hypermarkets on local consumption and distribution in Ubon Ratchathani, a regional city in northeast of Thailand. Results of the study showed that hypermarkets have succeeded in converting high-income level consumers in Ubon into customers. However, because Ubon does not have a sizeable middle-class population, hypermarkets have reached out to tourists and the local low-income groups. Second, although hypermarkets are direct and strong competitors to small domestic retailers, the domestic retailers in Ubon managed to survive better than expected. This could be due to the fact that hypermarkets are largely inaccessible to the poor, despite their low price policies, comfortable store layout and engaging entertainment options. Third, hypermarkets have not greatly influenced the distribution of agricultural products in Ubon. They continue to depend on traditional middlemen, who also act as educators to farmers and collect farming products efficiently. The findings of this study suggest that if hypermarkets want to expand further in rural areas, they need to attract new customers and introduce changes in the existing distribution network to capture the traditional advantage enjoyed by local domestic retailers, especially with regard to agricultural produce.     

Determinants of Public Service Broadcasting Size

We investigate the issue of whose interest is reflected in selecting the size of public service broadcasting (PSB). We examine two different approaches: (1) the public interest theory, where PSB size is selected to maximise citizens’ welfare and (2) the public choice theory, where PSB size is determined by self-interested politicians. Based on the foundations of these two views, we derive theoretical predictions about how PSB size changes with an increase in political competition. Then, we test these predictions using panel data from OECD countries over the period 1993–2010, and we find that the degree of electoral competition is negatively associated with PSB size. We conclude that PSB size does not reflect the public interest theory, but rather upholds the public choice theory, especially the politicians’ rent-seeking motive.     

The right place to grow rice for the Japanese market: comparative analysis of greenhouse gas emissions of rice cultivation in Japan and the United States

One consequence of increasing agricultural trade is a shift of geographic location of agricultural activity to more economically productive countries. Whether or not the economic efficiency translates to environmental efficiency for agricultural goods is an open question. To examine environmental implications of shifting agricultural location, we analysed the life-cycle greenhouse gas (GHG) emissions of rice production in Japan and the US for the Japanese market in a comparative manner. This paper presents the life-cycle assessment of brown japonica rice. Our computation of GHG emissions of rice production in Japan and the US were 3.54 and 2.99?kgCO₂-eq kg-rice^?1, respectively. With respect to harvested area, the emissions were 18.4 in Japan and 27.8?tCO₂-eq ha^?1 in the US. For Japan to be environmentally competitive with the US production, fundamental restructuration of field size is necessary to increase yield. In conclusion, economic efficiency does not translate to environmental efficiency with the case of rice production. Importing rice is both economically and environmentally viable option for the Japanese market.     

Asset Accumulation in Rural Households during the Post‐Showa Depression Reconstruction: A Panel Data Analysis*

This paper investigates asset accumulation in Japanese farm households during reconstruction following the Showa Depression. After the Showa Depression, farm households emphasized accumulation of cash and quasi‐money rather than productive assets. The accumulation of cash and quasi‐money is consistent with the buffer stock hypothesis. Evidence regarding accumulation of livestock, which is sometimes used as the buffer stock in modern developing countries, is not conclusive. The presence of well‐developed financial institutions in prewar Japan may have allowed farm households to smooth consumption via cash and quasi‐money.
