Assessing the relationship between the user-based market share and unit sales-based market share for pirated software brands in competitive markets

This article argues that in a competitive software market, in the presence of differential piracy and brand switching among the various brands within a software product category (e.g., spreadsheets), there may be no relationship between market estimates based on unit sales and the user base of a software brand (e.g., Lotus 1-2-3). Hence, marketing strategies developed for the software brand based on unit sales-based market share may be misleading. To support our argument and to quantify the relationship between unit sales-based market share and the user-based market share, we first extend a diffusion modeling approach for pirated software product categories to model the legal and illegal adoption dynamics of a software brand within a software product category. Second, to examine empirically the relationship between the user-based market share and the unit sales-based market share for a brand, we consider the diffusion of the major brands of two types of software product categories, spreadsheets and word processors, in the United Kingdom. Results indicate that in the product category of spreadsheets, for Lotus 1-2-3, the user-based market share was always less than the unit sales-based market share. On the other hand, in the product category of word processing software, the user-based market share for WordPerfect was always greater than the unit sales-based market share. Marketing implications of these results for Lotus spreadsheets, Novell WordPerfect, and the software industry are discussed.     

VC Fund Financial Performance: The Relative Importance of IPO and M&A Exits and Exercise of Abandonment Options

By combining data from two sources, we are able to examine how fund financial performance is related to fund outcomes (initial public offering [IPO] and merger & acquisition (M&A) percentages) and abandonment practices. We also are able to relate fund performance to the track record of the venture capital firm. Our primary findings include: 1) fund IPO and M&A outcomes are statistically significantly related to financial performance, 2) M&A success is around 60% to 80% as important as IPO success in explaining performance, 3) except among the top performers, funds with aggressive exercise of abandonment options outperform those that continue to support a large percentage of their initial investments, and 4) prior performance of the firm, in terms of success percentages and abandonment practices, is significantly related to fund performance. Results are robust to controlling for selection bias of the reporting entities, as well as biases related to looking back at the performance of earlier funds survivorship, and attrition. Quantile regression estimates establish that our results hold across the full range of realized performance levels.     

A critical review of methods for tourism climate change appraisal: life cycle assessment as a new approach

This paper reviews existing approaches to assessing tourism sustainability, especially its contribution to climate change. It assesses ecological footprint analysis, environmental impact assessment and input–output analysis but finds them inaccurate and unreliable. It goes on to argue that life cycle assessment (LCA) is a more promising tool for tourism climate change impact assessment, highlighting important areas where LCA application can contribute towards better understanding of tourism's role in global climatic changes. To demonstrate the applicability of the LCA methodology, a case study of a short weekend holiday trip is presented. Related greenhouse gas emissions are measured comparing LCA and alternative carbon footprint calculation methods. The comparison demonstrates markedly different results. The reasons for the discrepancy along with the potential of LCA to estimate the “indirect” carbon contribution of the holiday trip's components are discussed. A key feature of the LCA calculation is that for short-haul trips the proportional impact of accommodation-related emissions is shown to be larger than in earlier calculations, while transport impacts are reduced.     

Positioning of commodities using the Kraljic Portfolio Matrix

This article proposes a more objective methodology to classify and position commodities (works and services) in the Kraljic Portfolio Matrix (KPM) in a continuous scale around the two dimensions of supply risk and profit impact—the two dimensions which mainly influence the choice of a firm's purchasing strategy. Fuzzy multi-attribute scoring is used to assign performance scores to different commodities on supply risk as well as profit impact attributes. With a multidimensional scaling approach the commodities are placed in the KPM. An application of the proposed approach is attempted on commodities procured by the Rural Development Department of a state government in India.     

Multiple-Object Auctions with Budget Constrained Bidders

A seller with two objects faces a group of bidders who are subject to budget constraints. The objects have common values to all bidders but need not be identical, and may be either complements or substitutes. In a simple complete information setting we show: (1) if the objects are sold by means of a sequence of open ascending auctions, then it is always optimal to sell the more valuable object first; (2) the sequential auction yields more revenue than the simultaneous ascending auction used recently by the FCC if the discrepancy in the values is large, or if there are significant complementarities; (3) a hybrid simultaneous-sequential form is revenue superior to the sequential auction; and (4) budget constraints arise endogenously.     

Tax Policy When Countries Compete for Third Market Exports

We examine the welfare and other consequences of tax policy in a third market export model where duopolists located in two countries compete in prices. With tax competition between governments, we allow for welfare‐maximizing governments in the two countries to delegate tax setting responsibility to policy‐makers who have different objectives than the governments. The unique equilibrium in the tax competition environment involves both governments delegating tax setting responsibility to tax revenue‐maximizing policy‐makers. This equilibrium yields higher welfare for both countries than the outcome when the governments delegate to welfare‐maximizing policy‐makers. The paper also compares tax competition with tax harmonization and shows that when the entire export market is served, tax harmonization improves the welfare of the country that houses the low cost firm, while the other country may be immiserized.     

Implementing competitive strategies at the business unit level: Implications of matching managers to strategies

This paper argues that, for superior performance, it is necessary to attune the choice of the general manager to the strategy of the business unit (SBU). Data from 121 SBUs indicate that SBU competitive strategy interacts with several managerial orientations (functional background, locus of control, and problem-solving style) to influence SBU effectiveness. The theoretical and practical relevance of these findings are discussed, as are directions for future research.     

Location theory of the firm under price uncertainty

This paper presents a theory of location under price uncertainty employing a general utility and production function. The analysis is also conducted by incorporating a homogeneous production function. Risk preferences of the firm are treated as an integral part of the model.
