The dynamics of risk-sensitive allocations

This paper describes Pareto optimal allocations when agents have risk-sensitive preferences as formulated by Hansen and Sargent (IEEE Trans. Automat. Control 40(5) (1995) 968-971). Necessary and sufficient conditions are given for the existence and stability of steady states at which Pareto weights are time-invariant. When all agents are risk-sensitive with the same power reward function there is a unique interior steady state which is stable when the power is positive and unstable when the power is negative. When there is at least one agent with time-additive preferences eventually all risk-sensitive agents have zero Pareto weights.     

The methodology of profit maximization: An Austrian alternative

Conclusion While the MR=MC profit-maximizing model that is used almost religiously by the economics profession has been challenged over the years, it still remains the dominant model to explain firm behavior. However, its popularity does not mean that the model accurately describes what actually occurs in firm decision making. Given that modern mainstream neoclassical economists have failed (through omission or commission) to examine their models through the lens of time, they have lost that component that presents accuracy and enrichment to their arguments. This paper has incorporated challenges to the dominant neoclassical model that were fashioned by Rothbard and, to a much lesser extent, Baumol. In examining the work of both economists, we conclude that the Rothbard model is more complete, as it factors time into the model, where Baumol’s does not, which renders it fatally incomplete. Both authors, however, make a solid point that if one is to analyze the workings of the firm in the real world, other models such as revenue maximization must be taken into account if we are to assume that firms attempt to maximize profits. To be sure, there is much work to be done in the creation of alternative theories of the firm. Klein and others have attempted to build upon the work of Mises and Rothbard to construct a theory of the firm that can stand up to intellectual scrutiny and explain the various aspects of the decision making process within the firm. We attempt through this paper to add to this alternative theoretical construct.     

Agricultural Trade Reform and the Doha Development Agenda

This paper examines the extent to which various regions, and the world as a whole, could gain from multilateral trade reform over the next decade. The World Bank's Linkage model of the global economy is employed to examine the impact first of current trade barriers and agricultural subsidies, and then of possible outcomes from the WTO's Doha Round. The results suggest moving to free global merchandise trade would boost real incomes in sub‐Saharan Africa and Southeast Asia (and in Cairns Group countries) proportionately more than in other developing countries or high‐income countries. Real returns to farmland and unskilled labour, and real net farm incomes, would rise substantially in those developing‐country regions, thereby helping to reduce poverty. A Doha partial liberalisation could take the world some way towards those desirable outcomes, but more so the more agricultural subsidies are disciplined and applied tariffs are cut, and the more not just high‐income but also developing countries choose to engage in the process of reform.     

From Wood Panels to Mobile Phones: Strategic Diversification at Sonae Group

This article tells the story of growth and diversification at Sonae, now Portugal's largest company. Publicly quoted but still majority-controlled by its long-standing Chairman and CEO, Belmiro de Azevedo, it was founded in 1959 in the wood products business. It expanded from the 1980s to become the largest retail group in Portugal and has recently taken on the two incumbents in Portugal's mobile telephony market. It won the third license auction in 1997 and achieved a 22% market share within three years. As the biggest part of Sonae's technology investments, the move into mobile telephony played a big part in launching the Sonae share price on a roller-coaster path that has only recently steadied. The Sonae story illustrates the potential importance of long-term charismatic leadership and strategic vision by one person. It also provides insights into the factors that can help diversification to work.     

Overcoming the Fear Factor: Workforce Involvement and Health and Safety Offshore

Despite recent campaigns to present the UK oil and gas industry as one with an ever-improving safety record, there is overwhelming evidence that there hasactually been little or no improvement. The data presented in this article show the degree to which victimization and intimidation of the workforce on offshoreplatforms acts to prevent an open and constructive approach to safety management. A number of particular problems in relation to workforce involvement and the safety representatives and committee system are identified. The article concludes by placing these empirical findings within a policy context.     

Taste Parameters as Model Residuals: Assessing the "Fit" of an Armington Trade Model

We note that calibration parameters in a multi‐country Armington trade model play a role similar to that of econometric residuals: they allow the model to fit the data exactly. We use this premise to evaluate the “fit” of a standard multi‐country computable general‐equilibrium model. We find that the model relies heavily on these parameters to explain the pattern of trade. In 33 of the 46 commodity groups we assess, modeled economic behavior explains less than 20% of the variation in bilateral trade. In a calibration‐ as‐estimation experiment, we estimate the commodity‐specific elasticities of substitution consistent with a well‐fitting model and find that they are substantially higher than widely accepted estimates.     

What is the relationship between investor protection legislation and target takeover returns? Evidence from Europe

We show that investor protection legislation is an important determinant of the returns of target companies that are subject to takeovers within Europe. Announcement and post-announcement returns are higher in strong investor protection countries, which indicates that bidders are forced to offer larger premiums when the original offer is made, and are more likely to have to revise their offer higher before a takeover is successful. This is consistent with targets having relatively greater bargaining power in strong investor protection environments. Our findings are robust to the inclusion of common determinants of takeover returns.
