The Role of Indexing in Subject Retrieval

On first reading the list of speakers proposed for this institute, I became aware of being rather the "odd man out" for two reasons. Firstly, I was asked to present a paper on PRECIS which is very much a verbal indexing system-at a conference dominated by contributions on classification schemes with a natural bias, as the centenary year approaches, toward the Dewey Decimal Classification (DDC). Secondly, I feared (quite wrongly, as it happens) that I might be at variance with one or two of my fellow speakers, who would possibly like to assure us, in an age when we can no longer ignore the computer, that traditional library schemes such as DDC and Library of Congress Classification (LCC) are capable of maintaining their original function of organizing collections of documents, and at the same time are also well suited to the retrieval of relevant citations from machine-held files. In this context, I am reminded of a review of a general collection of essays on classification schemes which appeared in the Journal of Documentation in 1972. Norman Roberts, reviewing the papers which dealt specifically with the well established schemes, deduced that "all the writers project their particular schemes into the future with an optimism that springs, perhaps, as much from a sense of emotional involvement as from concrete evidence." Since I do not believe that these general schemes can play any significant part in the retrieval of items from mechanized files, it appeared that I had been cast in the role of devil's advocate.published or submitted for publicatio

What Fundamentals Drive World Migration?

OECD governments note rising immigration with alarm and grapple with policies aimed at selecting certain migrants and keeping out others. Economists appear to be well armed to advise governments since they are responsible for an impressive literature that examines the characteristics of individual immigrants, their absorption and the consequences of their migration on both sending and receiving regions. Economists are, however, much less well armed to speak to the determinants of the world migrations that give rise to public alarm. This paper offers a quantitative assessment of the economic and demographic fundamentals that have driven and are driving world migration, across different historical epochs and around the world. The paper is organized around three questions: How do the standard theories of migration perform when confronted with evidence drawn from more than a century of world migration experience? How do inequality and poverty influence world migration? Is it useful to distinguish between migration pressure and migration ex-post, or between the potential demand for visas and the actual use of them?

Fiscal and Monetary Policies and the Cost of Sudden Stops

This article investigates the effects of macroeconomic policy (monetary and fiscal) on output growth during financial crises characterized by a “sudden stop” in net capital inflows in developing and emerging market economies. We investigate 83 sudden stop crises in 77 countries over 1982-2003 using a baseline empirical model to control for the various determinants of output losses during sudden stop crises. Extending the baseline model to account for policies-- contractionary as well as expansionary-- we measure the marginal effects of policy on output losses. Simple descriptive statistics indicate no apparent correlation between the costs of financial crises and the economic policies pursed at the time. Once controlling for various pre-conditions and other factors, however, we find that monetary and fiscal tightening at the time of a sudden stop crisis significantly worsens output losses.Output losses, financial crises, sudden stops, fiscal policy, financial policy

NASA/DOD Aerospace Knowledge Diffusion Research Project. Paper 13: The information-seeking habits and practices of engineers

It is argued that only by maximizing the research and development process can the United States maintain and possibly capture its international competitive edge. Key to this goal is the provision of information services and products which meet the information needs of engineers. Evidence exists which indicates that traditional information services and products may, in fact, not be meeting the information needs of engineers. The primary reason for this deficiency is three fold. First, the specific information needs of engineers are neither well known nor well understood. Second, what is known about the information seeking habits and practices of engineers has not been applied to existing engineering information services. Third, the information professionals continue to over-emphasize technology instead of concentrating on the quality of the information itself and the ability of the information to meet the needs of the user

What explains the evolution of productivity and competitiveness? The innovation link

This paper addresses the recent evolution of productivity and competitiveness in Catalonia and their links with the innovation activity of firms. Firstly, it summarizes the evolution of productivity, competitiveness, firms' strategies and the state of innovation. A slowdown in productivity growth and increasing revealed difficulties in some world markets are real, and the weakness of innovation may be a reason. The paper then quantifies some of the links between innovation, productivity and competitiveness. Innovation has a positive impact on productivity and competitiveness. First of all, innovation expenditures induce cost advantages and these cost advantages are a significant explanation for firms' exports. Furthermore, product innovation helps exports, too. Moreover, R&D activities in Catalonia benefit from high spillovers, and productivity impact is even higher when firms develop R&D activities outside as well. Despite all this, the current level of innovation expenditure is comparatively low and shows signs of lack of dynamism. Firms need to switch from the current equilibrium to the requirements of the coming years.Labor productivity; Competitiveness; innovation; cost;

What Drives Long-term Capital Flows? A Theoretical and Empirical Investigation

What drives capital inflows in the long run? Do they follow the predictions of neoclassical theory, or are other forces at work? The purpose of this paper is to illustrate how long-term capital movements conform surprisingly well to the predictions of a simple neoclassical model with credit constraints. The most surprising prediction of this class of models is that, contrary to a pure neoclassical model, domestic savings should act as a complement rather than a substitute to capital inflows. Nevertheless, this class of models keeps the neoclassical prediction that, ceteris paribus, capital should flow to the countries where it is most scarce. Using data on net foreign liabilities over the 1970 to 1997 period, I find evidence that supports these predictions.credit constraints, net external debt, capital flows, savings, convergence

What Makes Small Firms Grow? Finance, Human Capital, Technical Assistance, and the Business Environment in Romania

Although the development of a new private sector is generally considered crucial to economic transition and development, there has been little empirical research on the determinants of startup firm growth. This paper uses panel data techniques to analyze a survey of 297 new s small enterprises in Romania containing detailed information from the startup date through 2001. We find strong evidence that access to external finance (loans) increases the growth of both employment and sales. Taxes appear to constrain growth. There is some evidence that entrepreneurial skills increase growth, but only weak evidence for the effectiveness of technical assistance, and only when it is provided by foreign partners or international agencies. A wide variety of alternative measures of the business environment (contract enforcement, property rights, and corruption) are tested, but are found to have little or no association with firm growth.Earle, Romania, small, firms, growth, Upjohn
