Emissions Taxation in Durable Goods Oligopoly

This paper examines the use of taxation to control external damage due to pollution when product durability is endogenously determined. A special form of the emissions function is also examined which is equivalent to an excise tax on output. The model indicates that many conventional results in the durability and taxation literature need not hold when durability is endogenously determined. The analysis shows durability may not be independent of industry structure nor will firms minimize their manufacturing costs of providing service. In addition, the second-best tax on imperfectly competitive firms is not necessarily less than the tax on a competitive firm with endogenous durability.     

Negotiators' Communication, Perception of Their Counterparts, and Performance in Dyadic E-negotiations

The aim of this study was to improve our understanding of negotiation strategies, behaviors, and outcomes, and the relationships between these factors based on data collected from questionnaires, actual behavior during the negotiation process implemented using e-negotiation system, and the negotiation outcomes. This study clustered the negotiators based on either the negotiators' own strategies or their thoughts about those of their partners. This resulted in a division into cooperative and noncooperative clusters. We found that the negotiators whose own strategies are less cooperative tend to submit more offers but fewer messages. However, these people consIDer that they have less control over the negotiation process compared with those who adopt a more cooperative strategy, who make fewer offers but send more messages. Those in the cooperative cluster consistently feel friendlier about the negotiation and more satisfied with the outcome and their performance. Further, there is a correlation not only between self-strategies and the thoughts about partners' strategies, but also between strategies and final agreements. Finally, the proportion of negotiations reaching agreement is larger for the cooperative cluster than for the noncooperative cluster.     

Negotiation via the World Wide Web: A Cross-cultural Study of Decision Making

INSPIRE is a Web-based system for the support and conduct of negotiations. The primary uses of the system are training and research. Between July 1996 and April 1997, 281 bilateral negotiations were conducted through the system by managers, engineers and students from over 50 countries. INSPIRE has been used at eight universities and training centers. In research it is being used to study cross-cultural differences in decision making and the use of computer support in negotiation. This paper outlines the system, the negotiation methodology embedded in it, and reports the initial results of the experimental study of the impact of culture on Web-based bilateral negotiation.     

The Effect of Labor Market Demand on U.S. CEO Pay Since 1980

This paper shows that the rise in U.S. chief executive officer (CEO) pay from 1980 to 2003 is only partially explained by competition for profit‐producing talent in the labor market. This conclusion is obtained by removing unintended data biases from tests of the only theoretical model in the literature that relates labor market competition (measured by large firm size) to CEO pay level. When the biases are removed or minimized, no more than 33% of the 600+ percentage rise in large‐firm CEO pay since 1980 is explained by a corresponding increase in large firm size.     

Understanding the Backus–Smith puzzle: It's the (nominal) exchange rate,stupid

Backus, Kehoe and Kydland (BKK 1992) demonstrated that if international capital markets are complete, consumption growth correlations across countries should be higher than their corresponding output growth correlations. In stark contrast to the theory, however, in actual data the consumption growth correlation is lower than the output growth correlation. By assuming trade imperfections due to non-traded goods, Backus, D.K., Smith, G.W. [1993 Consumption and real exchange rates in dynamic economies with non-traded goods. Journal of International Economics 35(3–4), 297–316] showed that there is an additional impediment at work that can lower the consumption growth correlation. While their argument was successful in partially explaining the puzzlingly low cross country correlation of consumption growth rates, it contributed to generating another puzzle because the data forcefully show that consumption growth is negatively correlated with the real exchange rate, which is also a violation of the theory. Using data for OECD countries, we decompose real exchange rate growth into its nominal exchange rate growth and inflation differential components, and find that nominal exchange rate movements are the main source for the Backus-Smith puzzle. We demonstrate the robustness of this finding by examining sub-samples of the data, by allowing for imperfect risk sharing due to ‘rule of thumb’ consumers, and by examining intranational data across the U.S. states where the nominal exchange rate is fixed.     

Experiments on Damage-Based Ambient Taxes for Nonpoint Source Polluters

This article presents experimental tests of a linear and a nonlinear ambient tax mechanism that involve modest information requirements for the regulator. When agents are not allowed to communicate, both tax mechanisms result in emission levels that approximate the social optimum. When agents can communicate, emissions are considerably below the optimum, but we show that the tax function can be scaled to achieve social efficiency. Finally, by disaggregating the overall efficiency measure, we show that changing the pollution threshold that triggers the tax increases the inefficiency resulting from variation in agent-level decisions, but does not affect average emissions.     

Self‐protection from weather risk using improved maize varieties or off‐farm income and the propensity for insurance

We investigate how self‐protection from the adoption of Improved Maize Varieties (IMV) and off‐farm income affects risk premiums for smallholder maize producers in Uganda. To unbundle these effects, we specify the cost of risk to explicitly capture four risk components—mean, variance, skewness, and kurtosis. Using unique plot‐level panel data for Uganda, we estimate and test moments of a flexible production function based on an expanded form of the Johnson S_U family distribution and proceed to simulate the degree of responsiveness of risk premiums and welfare estimates to marginal changes in the share of land under IMV and off‐farm income. Scenarios of joint adoption of IMV accompanied with low and high application of inorganic fertilizer, and the effect of off‐farm income when there is high and low supply of farm labor are examined. Results show that the use of IMV and off‐farm income substantially reduces risk premiums and the individual effect is much higher under low fertilizer application and high supply of farm labor, respectively. Thus implying that self‐protection is likely to reduce the propensity for index insurance especially if its design fails to consider the reduction in downside risk.     

International Evidence on Financial Derivatives Usage

Theory predicts that nonfinancial corporations might use derivatives to lower financial distress costs, coordinate cash flows with investment, or resolve agency conflicts between managers and owners. Using a new database, we find that traditional tests of these theories have little power to explain the determinants of corporate derivatives usage. Instead, we show that derivative usage is determined endogenously with other financial and operating decisions in ways that are intuitive but not related to specific theories for why firms hedge. For example, derivative usage helps determine the level and maturity of debt, dividend policy, holdings of liquid assets, and international operating hedging.     

Evaluating the bases of supplier segmentation: A review and taxonomy

A taxonomy of segmentation bases is presented which builds a multi-disciplinary approach to the categorization of suppliers. Supplier segmentation, from a purchasing perspective, still appears to be in the early stages of providing a coherent strategic intent behind supplier assessment. Whilst fragmentary in nature, current portfolio models are grouped into two principal taxonomic constructs of power and dependence and relational factors. In particular, the prevalent use of transaction cost economics (TCE) in portfolio modelling provides a foundation for purchasers to appraise risks from supplier opportunism. We augment existing approaches with reference to inter-organisational theory and the resource-based view to show different modes of inter-firm value creation that act as constituents of a strategic intent for segmentation. Our resulting taxonomy draws together a holistic view of supplier segmentation covering supply market conditions, product/service characteristics, supplier characteristics, buyer characteristics, and buyer-supplier relational factors.
