IDENTIFYING AND ESTIMATING SOURCES OF TECHNICAL INEFFICIENCY IN KOREAN MANUFACTURING INDUSTRIES

This study estimated translog stochastic frontier production functions using an unbalanced panel of Korean manufacturing firms in the food, textile, paper, chemical, basic-metal, and fabrication sectors. The sectors were estimated individually to investigate whether technical efficiency is systematically related to firm size, dependency on external funds, research and development investments, and exports. The empirical results suggest that firm size has a positive and significant effect in every sector. The effects of the other factors are less systematic and vary across sectors.     

HIGH‐TECH AND HIGH CAPABILITY IN A GROWTH MODEL*

A growth model is developed to substantiate the conventional wisdom that regards high‐tech high‐capability firms as an engine of sustained technological progress. High‐tech industries are characterized by abounding technological opportunities, which promote endogenous high capability firms due to a competitive escalation mechanism. While high‐tech high‐capability firms capitalize on and discharge the existing innovation potentials, they also contribute to recharge (due to knowledge spillovers). They are a source of growth and high wage rate. An inquiry into the reasons why the high‐tech/high‐capability growth mechanism is not widely adoptable across countries points to the role of the underlying corporate governance systems.     

THE SOURCES OF AGGREGATE PRODUCTIVITY GROWTH: US MANUFACTURING INDUSTRIES, 1958–1996

The sources of aggregate productivity growth are explored using detailed data for four‐digit US manufacturing industries during 1958–96 and a decomposition formula that allows us to quantify the contribution of structural change. Labour productivity as well as total factor productivity are considered with either value‐added or employment shares serving as aggregation weights. It is shown that structural change generally works in favour of industries with increasing productivity. This effect is particularly strong in the years since 1990, in high‐tech industries and in durable goods producing industries. The impact of the computer revolution can be clearly identified.     

TEMPORARY EMIGRATION AND WELFARE: THE CASE OF LOW‐SKILLED LABOR

This article studies the implications of temporary emigration for the welfare of a source country. The framework is one of general equilibrium, where the economy's stocks of both capital and labor are endogenously determined by the saving and migration decisions of optimizing agents. Simulations of the model suggest that for realistic values of the parameters, welfare of nonmigrants of the source country is maximized when the migrants are employed abroad for a period in the range of roughly 8–12 years. The ideal duration is found to be an increasing function of the international wage differential, migration costs, and the degree to which the rights of migrants are protected in the host country.     

FINANCIAL DEVELOPMENT AND THE SOURCES OF GROWTH AND CONVERGENCE*

We extend the deterministic, nonparametric production frontier framework by incorporating financial development. Our analysis convincingly shows that (1) failure to account for financial development overstates the role of physical capital accumulation in labor productivity growth, (2) most of this overstated contribution stems from the efficiency‐enhancing role of well‐functioning financial institutions, (3) international polarization is solely driven by efficiency changes, and (4) increased distributional dispersion of productivity is primarily driven by technological change. Model’s extensions to account for the growth effect of changes in the institutional environment only add to the argument about the overstated role of physical capital.     

MINIMUM WAGE HIKES AND THE WAGE GROWTH OF LOW‐WAGE WORKERS

This paper presents difference‐in‐differences estimates of the impact of the British minimum wage on the wage growth of low‐wage employees. Estimates of the probability of low‐wage employees receiving positive wage growth have been significantly increased by the minimum wage upratings or hikes. However, whether the actual wage growth of these workers has been significantly raised or not depends crucially on the magnitude of the minimum wage hike considered. Findings are consistent with employers complying with the legally binding minimum wage but holding down or offsetting the wage growth that they might have awarded in periods of relatively low minimum wage hikes.     

EFFECTS OF PATENTS ON PRODUCTIVITY GROWTH IN KOREAN MANUFACTURING: A PANEL DATA ANALYSIS*

Abstract.  We analyse the contributions of patents to total factor productivity (TFP) performance in Korean manufacturing industries during the period 1981–1999. This paper treats potential autocorrelation problems seriously and uses recent panel cointegration approaches to investigate the robustness of the patent-TFP relationship. The results show that both domestic and foreign-resident patent applications have significant positive effects on productivity and that foreign-resident patent applications have a larger effect than domestic patents in improving TFP in Korean manufacturing. We also find evidence of knowledge spillovers among industries, in that the patent applications of other industries increase TFP in any single industry.     

CREDIT CRUNCH AND HOUSEHOLD WELFARE,THE CASE OF THE KOREAN FINANCIAL CRISIS*

We examine how the credit crunch in Korea in the late 1990s affected household behaviour and welfare. Using 1996–1998 household panel data, we estimate a consumption Euler equation, augmented by endogenous credit constraints. Korean households coped with the negative shocks of the 1997 credit crunch by reducing consumption of luxury items while maintaining food, education and health related expenditures. Our results show that, in 1997–1998, during the crisis, the probability of facing credit constraints and the resulting expected welfare loss from the binding constraints increased significantly, suggesting the gravity of the credit crunch at the household level.     

GROWTH AND FAILURE OF MANUFACTURING ESTABLISHMENTS IN AUSTRALIA*

This study examines the determinants of failure and employment growth for manufacturing establishments in Australia between 1984 and 1985. For the sample of all establishments which operated in 1984, initial size of establishment is found to be inversely related to the probability of establishment failure and positively related to the establishment-level rate of employment growth. However, excluding establishments which ceased operation between 1984 and 1985, no relation exists between size of establishment and employment growth. These findings indicate the importance of sample selection for studies of the determinants of establishment-level employment growth. Industry sector does not appear to have a strong effect on failure or on employment growth of establishments.     

INDUSTRIAL PERFORMANCE AND COMPETITION: THE CASE OF JAPANESE MANUFACTURING

Abstract.  The paper analyses the competitive process and performance behaviour of Japanese manufacturing between 1985 and 1997. Technological changes, international competition and reducing barriers in domestic and international markets are playing a significant role to speed up the performance behaviour in Japanese manufacturing. Scale economies, product differentiation and openness of the economy are used in explaining profit behaviour of manufacturing firms. Findings are compared with existing studies from Japan as well as from other developed countries such as Australia and the USA.     

SOURCES OF PRODUCTIVITY GROWTH IN AUSTRALIAN TEXTILE AND CLOTHING FIRMS*

This paper estimates the sources of productivity growth in Australian textile and clothing firms based on the Business Longitudinal Survey (BLS) from 1995 to 1998. Productivity growth estimates have been obtained for each sub‐category of textile and clothing firms. Sources of growth in multifactor productivity (MFP) are examined with growth in technical efficiency and scale effects based on estimates of stochastic frontier production functions. Separate estimates of output growth have been compared with the productivity growth estimates for each of the product categories. MFP improved in all clothing firms and declined in textile firms over 1997–1998 by four‐digit level of Australia New Zealand Standard Industrial classification Scheme (ANZSIC). MFP declined in most major categories of both textile and clothing firms in 1995–1997. Changes in technical efficiency mostly dominated scale effects in the overall direction of MFPG in both textile and clothing firms. The findings of the study provide evidence for policies for improving the firms’ operative performance in the ongoing liberalised regime.

OVERSEAS NETWORK OF EXPORT PROMOTION AGENCY AND EXPORT PERFORMANCE: THE KOREAN CASE

Governments have established export promotion agencies (EPAs) in an effort to boost exports. Despite criticism regarding the effectiveness of EPAs, the policy has not been abandoned and there has been an increasing recognition of the benefits on the basis of economic justification, including market failures. Such policies must be based strictly on evidence. Are EPAs truly crucial for export success? Some have argued that export success in Korea has been due largely to government policies targeted at the promotion of exports. This paper demonstrates that the network of EPA offices abroad has been a critical factor in the success of Korea's exports. An increase of 10% in the budget of EPA's overseas offices has been shown to increase exports by 2.45%–6.34%. The findings of this paper present a clear rationale for government intervention.

TRADE LIBERALIZATION AND THE MANUFACTURING SECTOR: THE CASE OF THE SMALL DEVELOPING COUNTRY

Historically, the lack of competition in developing countries has resulted in highly concentrated domestic industries that suffer from diseconomies of scale but prosper behind high walls of protection. Liberalization is expected to reverse this trend but at what cost? This article utilizes an import demand framework to examine the potential impact of trade liberalization on the manufacturing sector in the Caribbean using the case of Barbados. The results indicate that the manufacturing industry could encounter tremendous price competition, which could compromise the future survival of these industries. The study recommends that industries reorganize production processes to increase efficiency, which will allow them to compete effectively in the new global trading environment. These results may also be applicable to the wider Caribbean.     

INFRASTRUCTURE AND PRODUCTION EFFICIENCY: AN ANALYSIS ON THE KOREAN MANUFACTURING INDUSTRY

This study estimates an aggregate production function of manufacturing industry using panel data of 11 Korean regions covering 1977–1992. While the previous studies regard infrastructure as a direct input for production, the present study proposes that infrastructure has an effect on actual output by enhancing technical efficiency thereby, reducing the gap between maximum potential output and actual output. To investigate the relationship between infrastructure and technical efficiency, a stochastic frontier approach is applied to Korean manufacturing industry. Confirming the presence of substantial technical inefficiency in production, this study shows that an increase in infrastructure reduces the technical inefficiency level. The study also finds that, contrary to expectation, the industrialized regions are less efficient than the less industrialized ones. (JEL O20, H54, C23)     

REPEATED MORAL HAZARD AND CONTRACTS WITH MEMORY: THE CASE OF RISK‐NEUTRALITY*

We consider a repeated moral hazard problem where both the principal and the wealth‐constrained agent are risk‐neutral. In each of two periods, the agent can exert unobservable effort, leading to success or failure. Incentives provided in the second period act as carrot and stick for the first period, so that the effort level induced in the second period is higher after a first‐period success than after a failure. If renegotiation cannot be prevented, the principal may prefer a project with lower returns; i.e., a project may be “too good” to be financed or, similarly, an agent can be “overqualified.”
