Productivity growth and the structure of production

In this study, interactions between potential hierarchical value chains existing in the production structure and industry-wise productivity growths are sought. We applied generalized Chenery-Watanabe heuristics for matrix linearity maximization to triangulate the input-output incidence matrix for both Japan and the Republic of Korea, finding the potential directed flow of values spanning the industrial sectors of the basic (disaggregated) industry classifications for both countries. Sector specific productivity growths were measured by way of the Trönquvist index, using the 2000-2005 linked input-output tables for both Japan and Korea.

Expansion of Asparagus Production and Exports in Peru

Peru is the one of the most important exporters of asparagus in the world. Its export volume of fresh asparagus is ranked number one, and its export volume of preserved asparagus number two, globally. The objective of this paper is to provide an overview of the recent trends in asparagus production and exports around the world and to analyze factors in the development of the Peruvian asparagus industry. The production of asparagus has spread geographically. The center of its production used to be in the principal consuming countries, such as France, Germany and the United States. Afterward, it spread to neighboring countries such as Spain and Mexico where production factors such as climate and labor costs are favorable. After the rise and fall of Taiwan as a major preserved white asparagus exporter, China and Peru replaced its position. Finally, in recent years, Peru expanded its fresh green asparagus exports to the U.S. market by taking advantage of the increasing demand for fresh vegetables and supplying produce in seasons when neither U.S. nor Mexican producers can harvest. In addition to the changing factors in the international market, there are several factors in the development of the industry: high yields of produce due to favorable climatic and soil conditions; the introduction of the drip irrigation system, which enabled desert cultivation; the integration of production and exports, which is indispensable for fresh produce exports; and the collective efforts of the industry with help from the public sector.

A New Measurement for International Fragmentation of the Production Process: An International Input-Output Approach

The paper investigates the possibility of constructing a new measurement for analysing international fragmentation of the production process. It asserts that the current usage of relevant data, whether the trade shares of parts and components or the index of Vertical Specialisation, is quite unsatisfactory for measuring the phenomenon, since they critically lack the overall perspective of the entire structure of production chains. 　The new measurement is formulated such that it captures every aspect of the vertical sequence of production linkages. It is based on the input-output model of Average Propagation Lengths, recently developed by Eric Dietzenbacher and others, which show the average number of production stages that are passed through for an exogenous change in one industry to affect another. By applying this model to the data of the Asian International Input-Output Tables, the index is able to measure the international dimension of production sharing and division of labour in East Asia.

Production Networks and Spatial Economic Interdependence: An International Input-Output Analysis of the Asia-Pacific Region

The Asia-Pacific Region has enjoyed remarkable economic growth in the last three decades. This rapid economic growth can be partially attributed to the global spread of production networks, which has brought about major changes in spatial interdependence among economies within the region. By applying an Input-Output based spatial decomposition technique to the Asian International Input-Output Tables for 1985 and 2000, this paper not only analyzes the intrinsic mechanism of spatial economic interdependence, but also shows how value added, employment and CO2 emissions induced are distributed within the international production networks.
