    Computer Usage and Demand for Paper/Paperboard Products
    (Georgia Institute of Technology, 2007-04-09) Lei, Lei
    The purpose of this paper is to analyze the effect of computer usage on the demand for paper and paperboard products. A log-linear model is developed to analyze the effect of computer usage on the demand for four categories of paper, newsprint, printing/writing paper, packaging paper and household/sanitary paper. The analysis is divided into two parts. The first part is US monthly analysis. We create computer number index as a measurement for computer usage. Monthly data (from Jan 1992 to Jun 2005) are collected to estimate the effect for four categories of paper. The monthly estimation results support the hypothesis that the increasing usage of computer has a significantly negative effect on the demand for printing/writing paper, and a significantly positive effect on the demand for packaging paper. But it doesn't provide enough evidence for the effect on the demand for newsprint. The second part is the yearly analysis on 16 main countries, which constitute the major demand for paper/paperboard products and are countries with widespread usage of computer. Using the yearly data from 1961 to 2002 and applying fixone model, we find that computer usage has a significantly positive effect on demand for packaging paper. The small difference in US monthly analysis and 16 countries yearly analysis may arise from the different measures in computer usage, prices of paper/paperboard products, and income.

    Does market concentration motivate pulp and paper mills to vertically integrate?
    (Georgia Institute of Technology, 2005-09-02) Wang, Gewei
    Following sound economic theory, paper mills vertically integrate into pulp production, partly because internalizing the production of their inputs allows them to avoid transaction costs. Higher market concentration, a proxy of higher asset specificity and transaction costs, should encourage vertical integration in the pulp and paper industry. However, this relationship has not been robust in previous studies or in our replication with updated FPL-UW data. Upon a deeper analysis of the data, this study should clarify the mechanism by which transaction cost can induce vertical integration in this particular industry, which does not have well-defined intermediate goods markets. In order to specify the pulp markets where paper mills are likely to trade, we construct a mill-specific concentration measure as a substitute to traditional regional concentration measures. We also narrow our sample to mills producing free sheet paper, the most profitable paper grade in this industry. With such model refinement, this research exhibits a significantly positive correlation between transaction cost and vertical integration.

    Price Behavior of Paper and Paperboard Industry
    (Georgia Institute of Technology, 2004-07-13) Zhang, Feng
    This paper presents a model of the probability of price response to the previous periods inventory absolute and relative level for U.S. paper and paperboard industry. The initial part of the paper contains a theoretical analysis of the phenomenon. The proposed framework indicates that the inventory level plays an important leading role in the price adjustment. The model is then estimated with monthly data extending from 1980 to 1999. The LPM and Probit models are used to estimate the effect of absolute and relative inventory level on the probability of price variations. The estimated results are in agreement with the oligopolistic market condition of U.S. paper and paperboard industry, showing the price upward adjustment is sticker and rigid than the price downward adjustment while the output level is indifferent to the previous months inventory fluctuation.
