Structure of Public Support for National Agricultural Research Systems: A Political Economy Perspective

This paper initiates development of a set of stylized facts concerning the structure of public support for national agricultural research systems (NARS) within a neoclassical political economy framework. The aim is to place public funding of NARS in the broader context of the overall level of direct government assistance to agriculture. Using a newly constructed data set on NARS expenditures over the 1970-85 period, we observe a growing disparity in agricultural research intensity ratios, which measure the level of public support for NARS in relation to agricultural gross domestic production (Aggdp ) between low and high-income countries. This growing disparity appears to be driven by much larger increases in support for agricultural research by high-income countries, coupled with a significantly slower growth in the size of their agricultural sector, despite the propensity of low and middle-income countries to increase real support to agricultural research. As per-capita incomes rise the public agricultural expenditure ratio, which measures public expenditures on agriculture relative to the size of the agricultural sector, Aggdp , increases substantially. Public expenditures on agriculture were indexed on agricultural and non-agricultural populations to give a rough indication of the increasing incentives for rural 'distributional coalitions' to seek a redistribution of public expenditures in their favor. A relative research expenditure (rre ) ratio is developed, which measures the proportion of total public expenditure on agriculture spent on agricultural research. It provides an indication of the relative importance given to research on agriculture within the constraints imposed by overall public spending on agriculture. In contrast to the agricultural research intensity ratios, the rre ratios suggest that agricultural research appears to command as large a share of the public purse devoted to agriculture in low and middle-income countries as it does in high-income countries. Expectations derived from the neoclassical political economy literature that research may have fared relatively better in high compared with low-income countries were not supported by the data.     

Airline safety: Perceived and actual

This study investigated how the American traveler perceives U.S. and foreign airlines in terms of safety, and compared that perception to the actual safety records of the same airlines. In addition, the relation of the respondents' ethnic origin and safety perceptions was examined. Results indicate that 1) there is a substantial portion of the population that favors U.S. airlines regardless of individual ethnic origin, 2) of those individuals who do not favor U.S. airlines there is a significant relationship between ethnic origin and the carrier's country of origin, and 3) there exists a considerable misperception of airline safety.     

GMM estimators with improved finite sample properties using principal components of the weighting matrix,with an application to the dynamic panel data model

GMM estimators have poor finite sample properties in highly overidentified models. With many moment conditions the optimal weighting matrix is poorly estimated. We suggest using principal components of the weighting matrix. This effectively drops some of the moment conditions. Our simulations, done in the context of the dynamic panel data model, show that the resulting GMM estimator has better finite sample properties than the usual two-step GMM estimator, in the sense of smaller bias and more reliable standard errors.     

THEORIES OF THE FIRM: IMPLICATIONS FOR STRATEGY RESEARCH*

Theories of the firm provide a perspective for thinking about organizational objectives and a framework for analysing important research problems. Here, we demonstrate the usefulness of several economic theories of the firm for guiding strategy research. We evaluate the relevance of each theory with regard to how the underlying conceptualization of the firm permits us to investigate issues of substantive interest to strategy researchers, and how compatible the assumptions contained within the theory are with the traditional strategy framework. We also examine the relevance of the theories from the viewpoint of philosophical methodology. We argue that, because of the integrative nature of strategy research, it is imperative for researchers to adopt multiple frameworks represented by different theories for the advancement of the field.     

Bankruptcy as a deliberate strategy: Theoretical considerations and empirical evidence

Bankruptcy and bankruptcy reorganizations have been identified as remedies for financial distress, but there is little agreement on their value to firms, managers, and the general economy. This paper provides a brief review of proposed bankruptcy strategies and some alternative views about their costs and benefits followed by an empirical study of the outcomes of 73 bankruptcies and subsequent reorganization efforts. The evidence suggests that there are few successful reorganizations, bankruptcy is a costly response to financial distress, and managerial choice in bankrupt firms is highly constrained by forces external to the firm. The diversity of stakeholder interests limits the value of global judgements about success or failure of bankruptcy strategies. Firm size dominates all other factors in predicting success in completing the reorganization process. Delayed filings primarily reflect failed efforts to avoid bankruptcy, not deliberate strategies. Reasons for the use of bankruptcy in spite of its high costs are discussed.
