Offshore Outsourcing and Non‐production Workers: Firm‐level Relationships Disaggregated by Skills and Suppliers

In analysing the impact of offshoring on the skill composition, previous empirical studies have established that offshoring firms employ more non‐production workers. However, not all non‐production workers are highly skilled. This paper disaggregates non‐production workers into the following three categories: (i) skilled non‐production workers, (ii) unskilled non‐production workers and (iii) non‐production workers with special skills for offshoring and other overseas business management. By linking our offshoring survey data with firm‐level data for Japanese manufacturing firms, this paper finds that the share of skilled non‐production workers tends to be significantly high in offshoring firms but that of unskilled non‐production workers is not. As offshoring has expanded from production to non‐production tasks, this result implies that the distinction between skilled versus unskilled workers becomes critical among non‐production workers. Using our unique data on supplier types in offshoring, this paper finds that the share of non‐production workers for the management of overseas activities tends to be high in foreign direct investment firms and in firms outsourcing to foreign independent suppliers, but not in Japanese firms outsourcing to offshore suppliers located abroad but owned by other Japanese firms. This difference indicates that coordination burdens are likely to be at least partly mitigated by common languages or shared business practices. These findings suggest that offshoring has different impacts on employment depending on suppliers and the worker’s skill. The principal results are confirmed robust even after various firm characteristics are controlled for in panel regressions, though we should not give any causal interpretations.     

ANALYSIS OF HOUSEHOLD LEISURE AND SHOPPING BEHAVIOR IN IBARAKI PREFECTURE, JAPAN

Understanding household leisure and shopping behavior is an important component of market research, shop location decisions, travel behavior, and consumer behavior studies. This paper estimates a gravity model of travel behaviors related to leisure and shopping trips in the Ibaraki Prefecture, Japan, based on a 1998 survey data set by Poisson regression. The overall results indicate that GDP per capita of cities of origin and of destination, population, train stations, and store area of the destination city affect trip flow positively. Intercity distance, store areas in the city of origin, and higher density in the city of origin negatively affect trip flow. Different variables distinctly affect the shopping behavior for different commodities.     

NATIONAL AND REGIONAL WAGE CURVES IN JAPAN 1981–2001

There is evidence in many countries of an inverse relationship between the real wages paid to workers and the unemployment rate in their local labor market, a so-called wage curve. However, the evidence to date for Japan has been rather limited. In this paper, we estimate wage curves for Japan using pooled cross-section time-series data from 1981 until 2001. The presence of a wage curve is confirmed. The wage curve has become slightly more elastic after the bubble economy of the 1980s than it was in the pre-bubble and mid-bubble period. The unemployment elasticity of pay is greater for males than for females. We also estimate regional wage curves using time-series data. The male wage curve elasticity is larger in the northern regions of Hokkaido and Tohoku and the western region of Shikoku, while it is smaller in the central regions of Hokuriku, Tokai and Kinki.     

A Theoretical Analysis of Liner Shipping Conferences and Strategic Alliances

We analyze the economic impacts of industrial organizational struggles on the international liner shipping market. Operating ratios of different markets are discussed by incorporating rate, service level, and other variables into a standard microeconomic model. If two different carriers agree on a shipping conference price and/or share a strategic alliance service level, and maximize consolidated profit, a member carrier finds it easier to make its operation profitable than the individual profit optimization case; other carriers are worse off in becoming profitable. If the carriers face inelastic demand, the price continues rising until demand becomes elastic enough for the equilibrium to be relevant. The conference is expected to play a coordination role so that the market does not become unsustainable in the adjustment process to reach equilibrium.     

Cost heterogeneity and the destination of Japanese foreign direct investment: A theoretical and empirical analysis

This paper first of all develops a Cournot oligopolistic model with heterogeneous firms to examine each firm's choice between export-oriented foreign direct investments (FDI) and FDI to serve the host-country market. It is shown that there exist a critical level of efficiency such that all firms below that level choose the former and those above it the latter. The hypothesis is tested using firm-level data on 118,300 Japanese firms covering the entire manufacturing sector. Multinomial logit estimates strongly support our theoretical findings.     

Sequential point estimation of the powers of a normal scale parameter

We consider the sequential point estimation problem of the powers of a normal scale parameter σ^r with r≠ 0 when the loss function is squared error plus linear cost. It is shown that the regret due to using our fully sequential procedure in ignorance of σ is asymptotically minimized for estimating σ⁻². We also propose a bias-corrected procedure to reduce the risk and show that the larger the distance between r and −2 is, the more effective our bias-corrected procedure is. Received August 2000     

Bi-objective decision support system for routing and scheduling of hazardous materials

This paper presents a Pareto-based bi-objective optimization of hazardous materials vehicle routing and scheduling problem with time windows and shows its application to a realistic hazardous material logistics instance. A meta-heuristic solution algorithm is also proposed, which returns a set of routing solutions that approximate the frontier of the Pareto optimal solutions based on total scheduled travel time and total risk of whole transportation process. It works in a single-step fashion simultaneously constructing the vehicle route and selecting the optimal paths connecting the routed locations from a set of non-dominated paths obtained in terms of travel time and risk value.     

Three-stage confidence intervals for a linear combination of locations of two negative exponential distributions

Mukhopadhyay and Padmanabhan (Metrika 40:121–128, 1993) considered the construction of fixed-width confidence intervals for the difference of location parameters of two negative exponential distributions via triple sampling when the scale parameters are unknown and unequal. Under the same setting, this paper deals with the problem of fixed-width confidence interval estimation for a linear combination of location parameters, using the above mentioned three-stage procedure.     

The Turnover of Market Leaders in Growing and Declining Industries: Evidence from Japan

This article explores the turnover of market leaders in the manufacturing and information and communications industries in Japan. We propose indices for market mobility by focusing on the turnover of market leaders and examine how the likelihood of the turnover of market leaders differs across industries. We provide evidence that market leaders are more likely to be replaced by competitors in growing and declining industries, relative to industries where the growth is more stable. Moreover, the results reveal that the turnover of market leaders is more likely to occur in research and development-intensive industries. Furthermore, the interaction effects of industry growth and concentration indicate that the turnover of market leaders is more likely to occur in declining industries with high concentration.     

Industrial development in Malaysia and Singapore: Empirical analysis with multiple‐cone Heckscher–Ohlin Model

This paper employs the multiple‐cone Heckscher–Ohlin model to analyze industrial development in Malaysia and Singapore. In particular, we focus on industrial upgrading along with capital accumulation as a key determinant for the cross‐country difference in production technology and income. By pooling two countries’ data on factor endowment and sectoral output in manufacturing from 1990 to 2008, we estimate the common industrial development paths of the two‐cone Heckscher–Ohlin model, the Rybczynski linear relationship between capital–labor ratio and sectoral output per capita. Our results demonstrate that, after controlling for quality of workers (by educational attainment), the two countries resided in different cones during our sample period, implying that Singapore succeeded in accumulating capital steadily with the support of foreign investment and upgrading its industry mix to make it more capital‐intensive. The separation of cones is also consistent with the observed gap in gross domestic product per capita between the two countries. Furthermore, we implement a factor‐augmenting productivity test to see the gaps in efficiency of capital and human‐capital‐augmented labor and confirm no significant difference between the two countries.
