Rural Development and Agricultural Growth in Indonesia, the Philippines and Thailand
No full textUnderstanding economic growth is central
to the study of development. Rural economic growth is an
important aspect of economic growth. Historically, rural
agriculture has employed most people in most countries, and
continues to do so today. Nevertheless, the casual
relationship between economic growth and growth in
agriculture remain poorly understood. This volume focuses on
economic growth in the agriculture sectors of Indonesia, the
Philippines and Thailand. Starting from similar positions,
the agriculture sectors of these economies have diverged
considerably over the last 40 years. This volume
investigates the ways in which policy, institutions,
investments, resource constraints and the reallocation of
agricultural labor have driven this divergence. It volume
documents the interplay of endowments, technology, the
accumulation of productive factors, policy, and advocacy in
the rural sectors of these three countries. It contributes
in its own ways to an explanation of the past. Good policy
rests on an understanding of successes and failures in the
past. This book is a critical contribution to such an understanding
The performance of Bulgarian food markets during reform
Full text linkFood policy often depends on markets and markets depend on institutions. But how good do institutions have to be before reforms can be launched? Relying on well timed surveys of agricultural prices and a joint study by the Government of Bulgaria and the World Bank on agricultural market institutions, this paper presents evidence that performance in food markets improved following significant policy reforms in Bulgaria, although public institutions remained weak. This suggests that even though strong institutions are preferred to weak ones, it can be costly and impractical to delay policy reforms until work on strengthening institutions is finished. Still, measured performance varied by place and by commodity, suggesting that markets developed at different tempos and that the distribution of benefits from improved markets was uneven. This points to the need to address the costs of adjustment as policies change. The paper introduces a new approach to measure market performance based on composite-error techniques.Markets and Market Access,Transport Economics Policy&Planning,Economic Theory&Research,Access to Markets,Agribusiness
Uncertainty and the price for crude oil reserves
Full text linkInnovations in futures, options, and derivative instruments permit active trading, speculating and hedging - linking markets for physical petroleum products with financial markets. These derivative markets continuously value petroleum delivered today and for future dates, providing a market price for inventories. Underground petroleum reserves are also an inventory defined by exploration surveys and development drilling. Thus, observable market information can be used to value these reserves. Option - valuation models can be used to price reserves using observable markets, but are dependent on unexplained convenience yields revealed by the term structure of futures prices. The authors apply a general inventory pricing model to petroleum inventories and generate an empirical model of the returns to storage for petroleum markets. They examine the determinants of the crude oil convenience yield using a stochastic control model. They specify optimal production and inventory conditions using a third-order cost function and estimate them using monthly observations. Their inventory arbitrage condition embodies the Hotelling principle and Kaldor's convenience yield, and includes a premium on the dispersion in crude oil prices. The empirical results suggest that returns to storage contain both a cost-reducing component and often sizable premiums associated with the dispersion of petroleum prices. Their findings suggest that crude oil markets differentiated by quality and location provide similar premiums. The premiums associated with the dispersion of petroleum prices may account for persistent backwardation in crude oil prices. This finding may also explain the wide discrepancies between Hotelling values and transaction prices found in previous studies.Economic Theory&Research,Environmental Economics&Policies,Markets and Market Access,Labor Policies,Payment Systems&Infrastructure,Oil Refining&Gas Industry,Environmental Economics&Policies,Access to Markets,Markets and Market Access,Economic Theory&Research
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
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
Indonesia's palm oil subsector
Full text linkDebate on Indonesia's palm oil policy was stimulated by a sharp increase in cooking oil prices in 1994-95 and a resulting increase in the export tax rate on crude palm oil. Palm oil has been one of the fastest growing subsectors in Indonesia. Using a quantitative model, the author analyzes the effect of government policies, including the export tax, buffer stock operations by the BULOG (the national logistics agency), and directed sales from public estates. The author acknowledges the export tax's effectiveness in lowering domestic prices, but observes that its impact on inflation and consumer welfare is minimal. The tax has also had the unintended effect of transferring income from oil palm growers located primarily off Java. The structure of the tax discourages local processing by squeezing processing margins. And determining tax rates on palm oil products independent from the underlying crude palm oil price creates uncertainty about marketing margins for processors. The author recommends repealing the tax and discontinuing buffer stock operations and directed sales from public estates. The author concludes with recommendations on investment policy. Direct incentives to private investors have been used to overcome investment risks and uncertainties, but investors should no longer need those incentives. Instead, Indonesia's government should focus more on alleviating obstacles to private investment. The Bank might be of assistance in this area.Markets and Market Access,Environmental Economics&Policies,Economic Theory&Research,Payment Systems&Infrastructure,Consumption,Economic Theory&Research,Consumption,Environmental Economics&Policies,Markets and Market Access,Access to Markets
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
