이 논문은 노조기업의 노동수요탄력성이 비노조기업의 그것보다 작을 것이라는 이론적 예측을 실증적으로 검증한다. 이를 위해 기업정보 TS2000의 1990~2009년 기간의 기업체패널 자료를 이용하여 노동수요함수의 정태모형과 동태모형 그리고 노동비용 비증방정식을 추정한다. 추정결과는 첫째, 노조기업의 노동수요의 임금탄력성은 0.34~0.49로 비노조기업의 절반 수준이하로 나타났다. 둘째, 노조기업은 임금 및 산출 변화에 대한 고용조정에서 비노조기업보다 더 경직적인 것으로 나타났다. 셋째, 노동과 자본간 대체탄력성에 있어서는 노조기업과 비노조기업 간에 차이가 없는 것으로 나타났다.

본 연구는 국제무역에 참여하고 있는 우리나라의 기업들을 대상으로 수출입이 기업의 노동수요에 미치는 영향을 살펴보았다. 통계청의 기업활동조사 데이터를 이용하여 2006년부터 2014년까지 제조업 24개 업종에 속해 있는 기업들의 수출입이 노동수요에 미치는 영향을 시스템 GMM 방법을 사용하여 분석하였다. 분석 결과, 생산성이 높은 기업에서는 수출이 늘어나면서 생산 확대를 위한 노동수요가 창출되는 효과가 나타난 반면 생산성이 낮은 기업에서는 이러한 효과가 유의하게 나타나지 않았다. 그러나 기업이 오프쇼어링을 이용하여 국내업무를 해외로 재배치한 경우, 수출이 유발하는 노동수요 증가 효과가 축소되는 것으로 분석되었다. 한편, 수입증대는 기업의 노동수요를 감소시키는 것으로 나타나는 데, 이는 수입제품이 노동을 대체하는 효과 때문인 것으로 보인다. 반면 기업이 오프쇼어링을 이용하는 경우, 생산 효율성 증대로 수입의 노동수요 감소효과가 완화되는 것으로 나타났다. 본 연구의 결과는 수출입이 기업의 고용에 미치는 영향은 기업의 생산성 및 글로벌 아웃소싱 참여 여부에 따라 달라질 수 있음을 시사한다.

As the uncertainty of demand in B2B electronics market has increased, firms need a strong method to estimate the market demand. An accurate prediction on the market demand is crucial for a firm not to overproduce or underproduce its goods, which would influence the performance of the firm. However, it is complicated to estimate the demand in a B2B market, particularly for the private sector, because firms are very diverse in terms of size, industry, and types of business. This study proposes both qualitative and quantitative demand forecasting approaches for B2B PC products. Four different measures for predicting PC products in B2B market with consideration of the different PC uses-personal work, common work, promotion, and welfare-are developed as the qualitative model's input variables. These measures are verified by survey data collected from experts in 139 firms, and can be applied when individual firms estimate the demand of PC goods in a B2B market. As the quantitative approach, the multiple regression model is proposed and it includes variables of region, type of industry, and size of the firm. The regression model can be applied when the aggregated demand for overall domestic PC market needs to be estimated.

This paper aims to investigate how and to what extent FDI impacts the relative demand for skilled labor within firms in the case of developing countries. The analysis uses a sizeable micro-level dataset for Malaysian manufacturing industries using the System-GMM estimators to control the estimations' endogeneity problems. For this purpose, the study uses foreign equity share at the firm level to investigate foreign ownership effects at the firm level and the Horizontal FDI index by Smarzynska Javorcik (2004) to analyze FDI intra-industry linkages influence on the structure of labor demand for Malaysian domestic firms. Our findings indicate that foreign ownership increases the skilled demand within Malaysian manufacturing through the learning process, exclusively for small- and medium-sized firms (SMEs). Conversely for foreign-owned firms, changes in their skilled-labor share do not associate with changes in firm-level foreign equity share. We conclude that foreign ownership per se is not the major contributing factor for skill upgrading in Malaysian manufacturing firms. Furthermore, the competitive pressures caused by foreign firms' presence within the same industry - namely horizontal FDI - has a significant negative spillover effect on the level of skilled-labor share for domestic firms in the Malaysian manufacturing sector within periods of the understudies.

In the past, a strategic management of work demands has been increasingly challenged to design-build (DB) firms. Such a management is capable of providing sufficient profitable impact of a project on them. Total project profit is mainly related to actual resources, work completion time, amount of rework, and costs. The degree of recycling work packages in the DB project delivery system is used as a measure of the quality of the performed work. However, there are few models available to evaluate the impact of a demand management strategy on the DB firms and to predict its behavior. We propose a decision-making support model as an aid for assessing the amount of rework and for predicting project profit resulting in a convincible demand management strategy. This model is constructed by using a dynamic feedback approach that can analyze the problems arising in complex managerial systems. For the purpose of illustration, widely acceptable strategies were applied into the model to explore their impacts on the DB firms. The results indicate that the model is helpful for the managers in selecting the most appropriate demand management strategy for successfully achieving their objectives.

Purpose - We study whether the bullwhip effect is prevalent among Korean firms and how the characteristics of it differ from the ones in other countries. Design/methodology/approach - We obtained quarterly financial and operational information on KOSPI-listed firms in manufacturing, wholesale, and retail industries from 2013 to 2019. We explore the variation of the bullwhip effect across firms and validate hypotheses. Findings - First, we find that for the KOSPI-listed firms, the bullwhip effect is more prevalent compared with the production smoothing. We provide additional findings by using sub-samples of manufacturing firms, wholesaling and retailing firms, big-sized firms, small- and medium-sized firms, domestic-sales intensive firms, and export intensive firms. Second, we show that in general, the bullwhip effect of Korean firms increases with the days in inventory or the demand seasonality ratio. However, the persistence of demand shock does not affect the bullwhip effect of Korean firms. Research implications or Originality - We compare our results with those in other studies that use information on the U.S. and Chinese firms. Our findings show that factors explaining the bullwhip effect across Korean firms have similarities and differences compared with firms in the U.S. and Chinese firms.

본 논문은 기업패널 자료(1997~2004)를 사용하여 노동조합 유무에 따른 기업유형별로 고용량 변동에 대한 제품수요충격의 효과가 어떻게 다른지를 분석하였다. 분석 결과에 따르면, 근로자특성별로 정도의 차이는 있지만 대체로 제품수요 감퇴 및 확대의 상황에서 유노조기업의 경우 무노조기업에 비해 고용탄력성이 작용 것으로 나타나 '제품수요 위축 시기에는 상대적으로 소폭의 고용감축으로, 제품수요 확장 시기에는 상대적으로 소폭의 고용확대로 대응하는,' 즉 제품수요 충격에 따른 고용변동성이 낮은 고용조정 패턴을 보여준다. 이러한 결과는 노동조합이 고용감축 시기에는 구성원의 고용안정성을 보장하는 데 유의미한 역할을 하는 반면, 고용확대 시기에는 고용수준 결정에서 그 역할이 매우 제한적임을 시사한다.

We analyze and study competition in differentiated product market using public data source. Understanding competitive market structure is critical for firms to assess how their products compete against other firms in a given market. In this paper, we estimate consumer demand, extend clout and vulnerability framework, and study competition among multi-product manufacturers in differentiated product market. For our empirical analysis, we adopt choice-based aggregate demand model and estimate consumer demand while accounting for unobserved product characteristics. Once we estimate consumer demand, we compute full price elasticity matrix and investigate intra- and inter- manufacturer substitutions among consumers. This research offers a framework for marketers to analyze and understand market structures, leading them to informed decisions.

This study aims to build a model dealing with the location decision of new manufacturing firms and their land demand. The model is composed with 1) the binary logit model structure identifying a future probability of manufacturing firms to locate in a city and their land demand; and 2) the land use suitability of the land demand. The model was empirically tested in the case of Anseong City. We used establishment-level data for the manufacturing industry from the Report on Mining and Manufacturing Survey. 48 industry groups were scrutinized to find the location probability in the city and their land demand via logit model with the dependent variables: number of employment, land capital, building capital, total products, and value-added for a new industry since 2001. It is forecasted that the future land areas (to 2025) for the manufacturing industries in the city are $5.94km^2$ and additional land demand for clustering the existing industries scattered over the city is $2.lkm^2$. Five industrial complex locations were identified through the land use suitability analysis.
