Firms' participation in exporting or foreign direct investment is an extremely rare behavior: only 4 percent of over 5.5 million U.S. firms were exporters in 2000. Exporters are generally larger (e.g. output and employment) and more productive than firms serving only domestic markets. Such heterogeneity within a narrowly defined industry...
This dissertation’s three essays investigate trade and productivity effects on firm behavior based on new heterogeneous-firms trade models in the case of Korea. In the first essay, firms’ decision to export in the case of Korean manufacturing industries is examined, where the change in firms’ productivity before and after exports...
A firm's productivity is composed of two parts: pure technical change and location-specific (agglomeration) externalities. Regional productivity is thus an aggregation of productivity of firms producing similar goods and located in a given region. International trade can affect both components of regional productivity. First, trade openness in a closed economy...
The objective of this dissertation is to theoretically and empirically examine the role of firm heterogeneity in terms of productivity and skill-intensity in the agglomeration process and the effect of agglomeration on regional economic development.
In the first essay, I analyze the effect of trade liberalization on agglomeration of high-...
Productivity Interfirm Comparison (PIC) is a simple
method used to improve productivity at the firm level,
where a number of firms operate in the same product line so
that performance information on the firms can be compiled
and compared. This results in identifying potential areas
for improvement or exploitation. The...
A unique team productivity raining program was developed and
implemented for Electro-Scientific Industries, Inc. (ESI). This program
was designed to train shop floor workers in teamwork skills and traditional
industrial engineering techniques. In this way, problem-solving
tools are available to the hourly manufacturing worker for use
in improving communications, quality,...
Based on the premise that interfirm comparison can be an effective
productivity improvement tool, productivity interfirm comparison (PIC)
methods are examined in this research. The first part is an extensive
literature review regarding the conventional interfirm comparison (IFC)
scheme accepted widely in many countries outside the United States.
Then, the...
The intent of this study was to survey opinions of
producine managers and industrial engineers concerning
several aspects of productivity. The survey was conducted
by means of a questionnaire. The number of questionnaires
administered was 540. Useful responses were 145 (27%).
In addition to English, there were versions of the...
This study focuses on the development of new, non-parametric efficiency measures based on the idea of aggregation via merging functions. We use Shephard's (1970) axiomatic approach of distance functions as the basis for theoretical methodology. In particular, this approach is a background for non-parametric efficiency measures defined on a linearly...
The objective of this dissertation is to examine multi-product firms' productivity and export behavior. More specifically, this dissertation estimates productivity of firms that produce and sell multiple products, and the role of productivity in such firms' export behavior. In doing so, this dissertation develops a firm-level gravity approach to test...
