Does public capital crowd out private capital? : evidence from India
Full text linkA recent but rapidly growing empirical literature focuses on the relationship between public and private capital. But for the most part, it ignores the heterogeneity of public investment. In many countries, especially in the developing world, public investment includes not only basic infrastructure projects, but also commercial and industrial projects similar to those undertaken by the private sector. And those two types of public investment are likely to have quite different effects on the accumulation of private capital. Using data from India, the author examines this issue empirically by implementing a simple analytical model encompassing two types of public capital. The empirical results show that in the long run capital for public infrastructure projects crowds in private capital - other types of public capital have the opposite effect. But in the short run, both kinds of public investment may crowd out private investment.Decentralization,Economic Theory&Research,International Terrorism&Counterterrorism,Banks&Banking Reform,Capital Markets and Capital Flows,Inequality,Economic Stabilization,Economic Theory&Research,Environmental Economics&Policies,Banks&Banking Reform
Uncertainty, instability, and irreversible investment : theory, evidence, and lessons for Africa
Full text linkA recent (but rapidly growing) literature has focused on how uncertainty and instability affect the adoption of fixed investment projects. That literature shows that if fixed investment projects are costly or impossible to reverse, uncertainty can become a powerful deterrent to investment. The author reviews the literature on irreversible investment to identify the implications for macroeconomic policy and to gauge the practical importance, especially for sub-Saharan Africa, of the link between uncertainty and investment. He presents empirical evidence on the negative association between investment performance and measures of instability, using cross-section time-series data. That evidence suggests that instability and uncertainty are important factors in Africa's poor investment record over the last two decades.Economic Theory&Research,International Terrorism&Counterterrorism,Environmental Economics&Policies,Fiscal&Monetary Policy,Decentralization,Environmental Economics&Policies,ICT Policy and Strategies,Trade and Regional Integration,Economic Theory&Research,International Terrorism&Counterterrorism
Private investment and macroeconomic adjustment : an overview
Full text linkThis paper reviews current investment theories, recent models linking macroeconomic policies and private investment, and the effect of uncertainty and credibility on irreversible investment decisions. Empirical studies on the subject are also reviewed, and the general implications of this literature for the design of growth-oriented adjustment programs are discussed.Economic Theory&Research,Environmental Economics&Policies,International Terrorism&Counterterrorism,Financial Intermediation,Banks&Banking Reform
Capital goods imports, the real exchange rate, and the current account
Full text linkConventional aggregate models of open economies typically rule out trade in capital goods. But capital goods account for a major share of the world trade. In 1990, they represented more than 40 percent of U.S. merchandise exports and more than 30 percent of its imports. In the same year, capital goods imports represented an average of roughly 30 of total imports for 82 industrial and developing countries, and almost 9 percent of their GDP. This report shows that the presence of imported capital goods greatly changes the short- and long-run effects of macoreconomic policies and external shocks on key macroeconomic variables. Using a rational-expectations aggregate model with intertemporally optimizing agents and with trade in both consumption and capital goods, it finds that the long-run equilibrium of the economy displays a negative relationship between the real exchange rate and real output - that is, a real appreciation is associated with an increase in long-run output and the capital stock. With investment subject to adjustment costs, the response to unanticipated permanent disturbances involves a changing real exchange rate and a non-zero current account. The author analyzes the macroeconomic consequences of changes infiscal policy and of transfers of wealth from abroad. He show that both have well-defined long-run effects on the capital stock and real output. Fiscal expansion, in particular, may have a long-run crowding-in effect on investment. By constrast, the impact of disturbances on the current account is ambiguous. The author shows that it depends critically on the degree of intertemporal substitutability in both consumption and investment - with the latter measured by the magnitude of investment adjustment costs.Economic Theory&Research,Environmental Economics&Policies,Macroeconomic Management,International Terrorism&Counterterrorism,TF054105-DONOR FUNDED OPERATION ADMINISTRATION FEE INCOME AND EXPENSE ACCOUNT
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Macroeconomic uncertainty and private investment in developing countries - an empirical investigation
Full text linkThe impact of uncertainty on investment has attracted considerable attention in the analytical and empirical macroeconomic literature. In theory, however, uncertainty can affect investment through different channels, some of which operate in mutually opposing direction. So, the sigh of its overall effect is ambiguous and can be assessed only empirically. To thoroughly assess the impact of macroeconomic uncertainty on private investment, the author uses a large panel data set on developing countries. He draws a distinction between sample variability and uncertainty, constructs alternative measure of the volatility of innovations to five key macroeconomic variables (inflation, growth, the terms of trade, the real exchange rate, and the price of capital goods), and examines their association with aggregate private investment. He then adds these constructed measures to an empirical investment equation that is estimated using alternative panel data econometric methods, allowing for simultaneity, country-specific effects, and parameter heterogeneity across countries. The results underscore the robustness of the link between investment and uncertainty. Virtually all of the volatility measures in the paper show a strong negative association with investment ratios. In addition, the regression estimates indicate that uncertainty has an adverse direct impact on investment, over and above any indirect effect that might also be at work. This finding is particularly robust in the case of real exchange rate volatility, which invariably has a robust negative effect on investment, regardless of econometric specification.International Terrorism&Counterterrorism,Economic Theory&Research,Environmental Economics&Policies,Fiscal&Monetary Policy,Payment Systems&Infrastructure,ICT Policy and Strategies,International Terrorism&Counterterrorism,Macroeconomic Management,Economic Theory&Research,Environmental Economics&Policies
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
